How Does a Hydraulic Pump Work

The advantage of using a hydraulic machine is that more force and torque can be generated with relatively smaller sized machines without requiring a gear system. An important component of a hydraulic machine is the hydraulic pump. The supply of fluids like oil and water to the various components of the machine is accomplished by using hydraulic pumps. Their mechanism is based on the displacement of the fluid volume against a resistant load or pressure.

Hydraulic Machinery

The machines that make use of fluid power to carry out the necessary function or to do work in general are called hydraulic machinery. In these machines, a fluid having high velocity is distributed to the hydraulic motors and hydraulic cylinders through tubes of small diameters. This fluid is known as the hydraulic fluid, and it can be oil, water, gas, etc. Control on the fluid is exercised with the help of control valves that are controlled automatically. A hydraulic pump is an important component of the working process of a hydraulic motor.

Basic Concept of Hydraulic Pumps

Basically, pumps are meant to impart energy to anything flowing through them. They transfer the fluid from a low potential to a high potential as in heat pumps. When a fluid enters a hydraulic pump, it has some velocity of its own. Now, with the help of an external energy source the pump boosts the velocity of the fluid. The rotating parts inside the pump carry out processes like confining the fluid in a certain volume and displacing it to increase its energy. It should be noted that hydraulic pumps do not generate any pressure, and they simply render the fluid with more velocity.

Positive Displacement Pump Principle

In general, pumps can be classified as positive displacement pumps and non-positive displacement pumps. Hydraulic systems mostly make use of positive displacement pumps. As the article is on the processing of hydraulic pumps, working of the positive displacement pumps will be discussed further. Positive displacement implies displacing a fixed quantity of something. In the case of hydraulic pumps fluids, a positive displacement pump has an increasing opening on the suction side of the pump and a decreasing outlet on the discharge side. When liquid flows in to the pump, it is forced out with greater velocity as the discharge side outlet is decreasing in size. Positive displacement pumps can further be classified under subcategories according to the motion pattern of the enclosed volume forming parts. Operating a positive displacement pump against a closed valve on the discharge side should be avoided, and a safety valve on the discharge side of this pump is mandatory.

Types of Positive Displacement Pumps

Reciprocating Pumps
This is the most basic type of positive displacement pump. In a reciprocating positive displacement pump, the moving part that is the piston, has a reciprocating motion. The discharge in this pump is pulsating and varies only when the speed of the pump is changed. The reason being that the intake is in constant volumes. Reciprocating pumps are often implemented for sludge and slurry. The two types of reciprocating pumps are plunger pumps and diaphragm pumps.

Metering Pumps
These pumps are used for precisely controlling very low flow rates. Flow rates are generally less than ½ gallon per minute. They are usually used to control additives to the main flow stream. These pumps are also called controlled volume pumps. Metering pumps have types such as diaphragm and packed plunger. Unlike the reciprocating positive displacement pumps, the metering pumps are meant to be used for clean fluids and impurities that can clog the valves of the pump.

Rotary Pumps
The rotary positive displacement hydraulic pumps come in the following types - the gear pumps, lobe pumps, vane pumps, progressive cavity pumps, peripheral pumps, and screw pumps. In these pumps, rotary motion carries the liquid from the pump inlet to the pump outlet. The fluid gets trapped in the closed casing of the rotary pump and is discharged in a smooth flow.

The basic information on the mechanism of hydraulic pumps, and their various types, has been provided above to give you an introduction to the subject. Hydraulics in itself, is a vast field and various books are available that will provide you more in depth information on the it.

Rebuild a Hydraulic Cylinder

Hydraulic systems are widely used in agriculture, construction and manufacturing industry. Bulldozers, cranes, tractors, elevators and all such heavy machines use hydraulics. Hydraulic hybrid vehicles are some of the newest developments in this field of technology. Hydraulics is an applied science, which exploits the mechanical properties of fluids to build hydraulic systems that can perform heavy duty mechanical jobs with precision. Hydraulic systems offer power with precise control and versatility. At the core of every hydraulic system is the hydraulic cylinder. It is the central component on which all hydraulic systems are dependent. Therefore, one must learn rebuilding these cylinders, as it saves money and valuable time.

Construction and Working

Any hydraulic system is made of two parts; the hydraulic pump that generates the pressure and the hydraulic cylinder that delivers the mechanical action in response to pressure. The cylinder is a barrel fitted with a piston, which fluidly moves back and forth. The cylinder barrel is of course sealed from both ends.

The piston divides the barrel body into two parts; the rod end, which is the side from where piston enters the barrel body and the other side, which is capped, called the cap end. The piston is driven back and forth, by the hydraulic fluid, which is mostly oil, introduced by the hydraulic pump. The piston has sliding rings and seals, which prevent the leakage of fluid from one part of the piston compartment, to the other part. The piston is connected with appropriate mounting arrangement. It conveys piston motion to appropriate moving part of the machine, which carries the load.

The idea behind every hydraulic system working is simple. The pressure applied at one point is conveyed to other point by the use of an incompressible fluid which is usually oil. So when the pump pushes oil into the piston chamber, from the cap side, the piston is lifted up. When oil is sucked back by the hydraulic pump from the chamber, the piston gets pushed down. This is how a hydraulic system works by conveying force through an incompressible fluid. By using pistons of different surface areas, force multiplication can be achieved. A heavier load can be lifted up by relatively lesser force, using this principle!

Repair Tips

Here are some common problems that can break a cylinder or cause its malfunctioning. I will outline the possible solutions that can help you rebuild or repair your cylinder. Read instruction manuals for the machine supplied by the manufacturers carefully, before going ahead.

Problem 1: The cylinder is cracked or piston rod is bent

Solution: If on observation, you see the cylinder rod is bent or the cylinder barrel is cracked, there is pretty much nothing you can do. It's time to replace the cylinder. Forging a new barrel or straightening the piston rod is beyond your capacity. So if this is the case, repairing the cylinder is not possible. In such a case, only a specialized repair shop can rebuild the cylinder for you, as a customized new shaft may need to be forged and the cylinder bore may need to be honed.

Problem 2: The seal is broken

Solution: If the shaft seal is broken, the pressurizing fluid leaks and loses pressure, impairing working of the cylinder. It can be replaced. However, an opening of the entire cylinder assembly is necessary. Let us see how we can go about it. Obtain a diagram of the cylinder if possible, as it will help you in reassembly. These diagrams can be had from the equipment manufacturers and you can also carry a printout. You can order a standard repair kit for your cylinder which is supplied by the manufacturing company. It includes spare cylinders, spare seals, O-rings and other spare parts according to the number and type of cylinders in your machine.

The assembly of the cylinder varies with machine type. Locate the seal position first. Mostly, you will find it around the shaft on one end. The shaft entry end can be accessed by unscrewing the lid from that side. You may need to unscrew the bolts, to remove the cover. Then loosen the pipes or valves that transmit the hydraulic fluid into the chambers which will release pressure. This will enable you to remove the shaft which otherwise cannot be removed due to hydraulic pressure. Handle the shaft carefully and take care that you do not scratch it. Detach the piston from the shaft and replace the seal with the spare one from the repair kit. Make sure that the seal is aligned rightly. Oil all parts after fitting and reassemble everything in exactly reverse order.

Problem 3: Piston Rings are damaged

Solution:If the piston rings are damaged, then they can be replaced too, by the same disassembling procedure, as for the above problem. The piston rings need to be removed and replaced very carefully. Oil the rings and cylinder assembly, before putting back everything together.

If you have a multiple cylinder arrangement, things are more complicated. It is better to consult a qualified technician before going ahead. Always remember one rule, while you are solving mechanical problems, do not proceed without a reason to take a particular action. Also, study the assembly and causative framework of the machine before going for repair. This repair can be a good learning experience for anyone who loves machine design.

Komatsu Introduces the World's First Hydraulic Excavator: Hybrid Evolution Plan for Construction Equipment

Komatsu Ltd. (President & CEO: Kunio Noji) announced today that the Company is going to launch sales of the PC200-8 Hybrid excavator, the world's first hybrid construction equipment. (*1)
The PC200-8 Hybrid is powered by the Komatsu Hybrid System which uses a newly developed electric motor which turns the upper structure, power generation motor, capacitor and diesel engine. Compared with the standard PC200-8 hydraulic excavator, the hybrid model achieves about 25% reduction of fuel consumption. (*2)
Earlier in May 2007, Komatsu launched the world's first hybrid electric forklift trucks on the market. We are introducing this hybrid excavator as it is our flagship construction equipment.
As a leading company of the construction equipment manufacturing industry, we are determined to meet the needs of the time by practically proposing innovative equipment designed to reduce environmental impact, including CO2 reduction.

1. Fuel Economy

Compared to the standard PC200-8, we have achieved an average of 25% reduction in fuel consumption. (*3) Furthermore, in the operation tests by customers, we have confirmed the maximum reduction of 41% at a jobsite where the machine's upper structure turns more frequently.

* Notes
1. Based on our research on seven major products (crawler-type hydraulic excavator, wheel-type hydraulic excavator, wheel loader, bulldozer, rigid-type dump truck, articulated dump truck and motor grader as of May 13, 2008.
2. This figure varies depending on the nature of work.
3. Computed according to our internal-use standard concerning average ways of using construction equipment.

2. Outline of the Komatsu Hybrid System

Our proprietary Komatsu Hybrid System converts energy generated when the upper structure reduces its speed while turning, stores the energy in the capacitor, and uses it to assist the power of the engine via the power generation motor when the engine accelerates.

All components of the Komatsu Hybrid System are made in-house , ensuring high reliability and durability.(*4)

* Note 4.Excluding capacitor cells.

3. Major Characteristics of the PC200-8 Hybrid when Compared to Standard Construction Equipment and Hybrid Cars

1) Comparison with Standard Construction Equipment
While standard equipment normally uses a hydraulic motor to turn the upper structure, for this movement, Komatsu has newly developed an electric motor for the Hybrid. By using this electric motor which collects energy generated when the upper structure's turns slow down, we have achieved a hybrid excavator.
While standard construction equipment uses only diesel engines for power, our new hybrid excavator utilizes regenerated energy to assist the engine when it is accelerating, enabling the use of the engine in a low revolution zone with high-efficiency combustion. In addition, while the engine runs idle, our hybrid excavator keeps the revolution at a super low level, achieving impressive reductions in fuel consumption.

2) Comparison with Hybrid Cars
Hybrid cars require a large amount of electric energy when they start moving and accelerating, then they can run with relatively stable engine revolution. By comparison, construction equipment has to accommodate dynamic and frequent fluctuations of the engine revolution, for example, for excavation work. To assist the engine for such fluctuations, the PC200-8 Hybrid is mounted with a capacitor.
Automotive batteries work on the principle of chemical reactions, thus it takes time for them to discharge electricity, lacking sufficient support when applied to construction equipment. Meanwhile, capacitors can instantaneously and efficiently collect, store and discharge electricity.

Komatsu America Corp. Launches New WA470-7 Wheel Loader

Komatsu America Corp. introduces the WA470-7 wheel loader. With a net horsepower of 272 hp (203 kW), the WA470-7 is powered by a Komatsu SAA6D125E-6 engine and is EPA Tier 4 Interim and EU Stage 3B emission certified. Built upon a proven Tier 3 engine platform, Komatsu has leveraged its leadership in technology and innovation to design a more environmentally-friendly engine that increases power while decreasing fuel consumption by approximately 8 percent, compared to the WA470-6.
Weighing in at 52,007 pounds (23,590 kg), the WA470-7 features improved efficiency, lower fuel consumption, improved operator comfort, and enhanced serviceability to maximize productivity while lowering operating costs.
The WA470-7 is equipped with the latest KOMTRAX® technology, which is fully integrated with Komatsu’s Tier 4 technology. Machine operating information such as operating hours, fuel consumption, location, cautions and maintenance alerts are wirelessly relayed to a secure website for analysis.  The KOMTRAX fleet monitoring system results in increased machine availability and, reduced risk of machine theft when compared to machines not equipped with KOMTRAX. The technology also allows for remote diagnosis by the distributor and provides a wealth of other information to drive business efficiency and productivity.
New features of the WA470-7 include:
• EPA Tier 4 Interim and EU Stage 3B Emission Certified Engine
Built upon proven Tier 3 technology, the SAA6D125E-6 engine provides lower emissions while also lowering fuel consumption. The Komatsu Tier 4 Interim engine uses an advanced electronic control system to manage air flow rate, fuel injection, combustion parameters and aftertreatment functions to optimize performance, reduce emissions, reduce fuel consumption and provide advanced diagnostic capability.
As a leader in hydraulic technology, Komatsu has also developed a hydraulically actuated Komatsu Variable Geometry Turbocharger (KVGT) and an Exhaust Gas Recirculation (EGR) valve, resulting in better precision and air management as well as longer component life. The Komatsu Diesel Particulate Filter (KDPF) has an integrated design that will not interfere with daily operation but will keep the operator aware of its status.
The WA470-7 also features Komatsu Smart Loader Logic (KSLL), which provides optimal engine torque for the job required. KSLL allows for fuel reduction by decreasing engine torque when the loader isn’t working hard, such as when it is driving with an empty bucket. KSLL functions automatically with machine operation and results in saving fuel without decreasing production.
• Large Capacity Torque Converter with Lock-Up
The WA470-7 has a newly designed Komatsu Large Capacity Torque Converter with Lock-Up as a standard feature. This provides improved acceleration, faster hill climb ability, a higher top speed and lower fuel consumption. The Lock-Up function activates in 2nd, 3rd and 4th gears giving the machine a maximum ground speed of 23.8 mph (38.3 kph).
The wheel loader has greater productivity in V-cycle applications because of the increased tractive effort. The faster hill climbing ability allows the WA470-7 to up-shift gears faster because of improved acceleration. The wheel loader can also achieve higher gear ranges and maintain higher ground speeds when working in load-and-carry applications. In most applications, production is increased and fuel consumption reduced, resulting in improved fuel efficiency.
• Enhanced Operator Environment
The new cab provides a more comfortable and quieter work environment so the operator can maximize productivity. The front glass has been lowered and the dashboard has been redesigned to improve visibility. Electronic Pilot Control (EPC) levers and an F-N-R switch are part of a redesigned seat-mounted right hand console. An auxiliary input has also been added to connect an MP3 player or other device along with two 12-volt ports that have been incorporated into the cab.
A new high resolution 7” LCD monitor features enhanced capabilities and displays information in 25 languages for global support. Using the monitor, the operator can easily modify settings for items such as the Auto Idle Shutdown or the auto-reversing fan. The operator can also check operational records, such as working hours or fuel consumption; monitor the KDPF soot load; or check how much time is required before the next maintenance interval. In addition, the monitor offers the operator the option of using the ECO Guidance (economy) function, which will provide operational tips to reduce fuel consumption. A separate high-resolution back-up camera is standard with every machine and is mounted on the right hand side of the console for operator convenience.
• Customer peace of mind is standard because of Komatsu CARE®
Komatsu remains focused on lowering the customer’s ownership costs by engineering machines with increased fuel efficiency and productivity. Komatsu CARE® complimentary scheduled maintenance is standard on all WA470-7 wheel loaders for three years or 2000 hours (whichever occurs first). Services are performed by factory certified technicians using only Komatsu genuine parts and fluids. Also included are two complimentary KDPF exchanges at 4,500 hours and 9,000 hours within the first five years.
• Convenient Maintenance and Serviceability
The WA470-7 provides easy service access in order to reduce downtime. The new model has increased cooling capacity, wider cooling fin spacing and a standard auto-reversing fan to help keep the radiator clean. The machine is equipped with the exclusive Komatsu Equipment Management Monitoring System (EMMS), which provides enhanced diagnostic features that give the operator and technicians greater monitoring and troubleshooting capabilities. EMMS continuously monitors all critical systems, as well as the planned preventative maintenance schedule, and provides troubleshooting assistance to minimize diagnosis and repair time.
Note: All comparisons and claims of improved performance made herein are made with respect to the prior model, WA470-6, unless otherwise stated.

Komatsu Introduces its Parallel Link Undercarriage System on Mid-Size Dozers

Rolling Meadows, IL, May 19, 2009 — Komatsu America Corp. introduced the new Parallel Link Undercarriage System (PLUS) on its D51EX/PX-22, D61EX/PX-15 and D65EX/PX/WX-15 crawler dozers. Komatsu’s revolutionary PLUS undercarriage can significantly increase wear life, reduce machine downtime and lower repair and maintenance costs.
With PLUS, undercarriage wear is more balanced across all components. Bushings will no longer wear faster than the rails. The system is designed to wear evenly so that the machine provides close to 100% usage of undercarriage components, lowering undercarriage maintenance costs by up to 40%.
Other advantages of PLUS include no maintenance between track changes other than track tension adjustments and no more bushing turns. The PLUS undercarriage is suitable for all applications including high impact applications and applications where the AR (abrasion resistant bushing) track assembly was previously required. Should service be required, the master links allows quick access to undercarriage components. PLUS also reduces noise heard by the operator, improving operator comfort.

PLUS’s strutted link provides a solid base for the box section type track and a taller, hardened link height provides longer wear. Because individual links can be replaced in the field, down time is minimized. Segmented sprockets are designed to shed material which minimizes packing. Carrier rollers have a larger diameter to increase their wear life, while track rollers with larger flanges and track roller guards that contact the link instead of the pins help maintain track alignment.
Building on Komatsu’s already robust track frame design, PLUS can be interchanged with a conventional undercarriage which makes retrofitting an existing machine simple and fast. Machines equipped with PLUS have undercarriage replacement options which include using the conventional undercarriage or using PLUS.
