What is an Axial Piston Pump?

Piston pumps are long-lasting and easy-to-use equipment. A piston, a chamber, and valves make up the main piston pump. The pump compresses the media within the chamber by forcing the piston down into the room.

Positive displacement pumps with several cylinders clustered around a central axis are axial piston pumps. A cylinder block is a collection of cylinders with an odd number.

A Swashplate has pistons in each cylinder. The swashplate is also famous as a cam or wobble plate and connects to a revolving shaft in different conditions. The angle of the swashplate varies as the shaft rotates. It does, however, move the pistons in and out of their cylinders.

The emphasis of this paper is on the Rexroth hydraulic Pump. The original producer of the Rexroth hydraulic pump is Zuosen hydraulic. We can provide you with authentic Rexroth axial piston pump spare parts in this area.

Benefits of Rexroth Axial Piston Pump  

The Rexroth axial piston pump is well-known for its two distinct structures. They usually do not need external energy oil's edge to supply them with the required energy; on the other hand, the Rexroth axial piston pump has just two motion components, making it exceedingly simple to operate.

This pump uses a relatively large amount of momentum in the oil movement to pump a relatively small amount of oil upward in elevation. However, there are several additional advantages to using a Rexroth hydraulic pump:

  • The pressure range is rather broad.
  • It is capable of controlling the force without affecting the flow rate.
  • Changes in flow rate and pressure have a negligible impact on the act.
  • With excellent control device design, skilled in moving heavy fluids, slurries, and abrasives.

Application of Axial Piston Pump

Axial piston pumps may incorporate most essential circuit controls by regulating the swashplate angle to manage flow and pressure. They're pretty dependable, and the remainder of the hydraulic system to which they're connected may be kept simple and low-cost.

Rexroth hydraulic pumps power the hydraulic systems of jet aircraft. You will often find them in-car air conditioner compressors for cabin cooling. Our pumps' design decreases vibrations while meeting the vehicle's engine bay's minimal weight and space requirements.

Axial piston pumps are prevalent in pressure washers, and axial reciprocating motors power many machines. Small earthmoving devices like skid loaders often use axial reciprocating engines to power.

Quick Installation and Startup of Rexroth A10VSO Hydraulic Axial Piston Pump

You must fill the axial piston unit with hydraulic fluid and airborne during commissioning and operation. Additionally, since the axial piston unit is empty through the hydraulic lines, you should see it after a more prolonged standstill.

Due to the potential of dry running, pay particular attention to the installation position "drive shaft upwards" or "drive shaft downward," as well as a thorough filling and air bleeding.

Use the highest case drain opening in the motor housing to discharge the case drain fluid into the reservoir (L1, L2, L3).

If you're using numerous units together, ensure sure the case pressure in each one isn't too high. If pressure discrepancies exist between the teams' case drain ports, you must alter the typical case drain line so that all linked units' minimum permitted case pressure doesn't exceed.

Decouple all connected lines using elastic components to obtain favourable noise levels and prevent above-reservoir installation.

The suction line and case drain line must flow into the reservoir below the minimum fluid level in all working circumstances. The complete pressure loss determines the suction height hS, which must not exceed hS max = 800 mm. The minimum suction pressure shall not fall below 0.8 bar absolute during operating at port S.

Rexroth hydraulic pump Troubleshooting

by increased noise, increased heat, inconsistent cylinder action, difficulty or inability to generate complete output, reduced speed of cylinders or hydraulic motors, or failure of the system to perform at all characterize pump issue.

In the following, we have outlined the most typical issues you may encounter while utilizing the Rexroth hydraulic pump.

Pump Cavitation

Cavitation occurs when a pump cannot pull in a complete charge of oil. When a pump begins to cavitate, the noise rises, and the shaft and front bearing get very heated.

Pump cavitation may also cause erratic cylinder movement, trouble building up to full pressure, and a milky look in the oil.

Air Leaking Into the System

The air in a newly built system will soon purify itself. The system should be cycled for 15 to 30 minutes without generating any pressure other than external pressure.

Entrapped air will gradually dissolve in the oil, and the system will transport it into the reservoir, where it will escape. Of course, leaking air from high places in the piping, particularly cylinder ports, may speed up the process.

Water Leaking Into the System

While the system is operating, water entering into the system can cause the oil to seem milky, but the oil will generally clear up once you turn it off as the water settles to the bottom of the reservoir.

Oil Leakage Around the Pump

Leaking around the shaft, leakage around a pump port and leakage around the body casting are all possible sources of oil leakage.

Rexroth Hydraulic Pump Maintenance Instructions

  • The A10VSO pump was explicitly built for an open circuit by Zuosen Hydraulic.
  • The axial piston unit requires trained staff for project design, installation, and commissioning.
  • Before using the axial piston unit, please read the corresponding instruction manual entirely and thoroughly.
  • Shortly after the operation, there is a possibility of burns on the axial piston unit, particularly on solenoids.
  • Take the necessary precautions (e.g. by wearing protective clothing).
  • The properties may change depending on the axial piston unit (operating pressure, fluid temperature).
