What is Rexroth Pump

 

 

Rexroth pump is a well - known brand of hydraulic pumps. It's widely used in industrial and mobile machinery applications.These pumps are designed to provide reliable and efficient fluid power transfer. They work based on the principles of positive displacement. The pumps can handle high - pressure hydraulic fluids and offer precise control over the flow rate. Rexroth pumps are integral components in machinery like construction equipment, factory automation systems, and many other hydraulic - driven devices, helping to ensure smooth and powerful operation.

Rexroth pump parts
 
01/

Pump Housing
The outer shell of the pump, protecting the internal components and providing structural support.

02/

Rotor/gear
In a gear pump, the rotor is the main component that generates hydraulic energy. For gear pumps, this usually includes gears, while for axial piston pumps, it is the axial piston.

03/

Plunger
In an axial piston pump, the plunger moves along the axis of the pump to compress and transport the liquid.

04/

Oil Distribution Plate/oil Distribution Groove
Helps distribute the liquid and control the flow direction to ensure that the liquid flows correctly inside the pump.

05/

Seals
Used to prevent liquid leakage and protect the internal environment of the pump.

06/

Rolling Bearings
Reduce friction between internal moving parts and extend the service life of the pump.

07/

Inlet And Outlet Ports
The liquid inlet and outlet of the pump, used to connect to the hydraulic system,

08/

Regulators
Some pumps are equipped with flow or pressure regulators to ensure that the output meets the system requirements.

09/

Filters
In some designs, the pump will include filters to prevent impurities from entering the pump.

10/

Hydraulic Booster
Used to increase the pressure of the system and further enhance the performance of the pump.

 

Application of Rexroth Pumps

Hydraulic System
Rexroth pumps are widely used in hydraulic systems, providing powerful oil delivery and pressure, improving the working efficiency and performance of mechanical equipment.

 

Engineering Machinery
Such as excavators, loaders, etc., Rexroth pumps provide the necessary power to support the operation of hydraulic arms, buckets and other components.

Working Principle Of Rexroth Pump

Oil Suction Process
When the closed volume of the pump (such as the space formed by the plunger and the cylinder hole) changes from small to large, negative pressure is generated, thereby sucking in liquid. For example, in a Rexroth plunger pump, oil suction occurs when the plunger is pulled out of the cylinder hole.

 

Oil Compression Process
When the closed volume changes from large to small, the liquid is compressed and generates high pressure, thereby being pressed out. In a Rexroth plunger pump, oil compression occurs when the plunger is pressed in..

 

Common types of Rexroth pumps
 
 

Plunger pump

Rexroth plunger pump is one of its main products. According to the different tilting elements, it can be divided into two types: inclined plate type and inclined axis type.

 
 
 

Vane pump

Vane pump is also an important type of Rexroth pump, which is widely used in various hydraulic systems.

 
 
 

Gear pump

Rexroth gear pump is suitable for conveying various liquids, with simple structure and reliable operation.

Frequently Asked Questions

 

Q: ‌What should I do if the plunger pump leaks internally?

A: Internal leakage may be caused by damaged seals, worn accessories or loose connections. You need to check and replace seals, repair or replace worn accessories, tighten connections, etc. ‌

Q: ‌What should I do if the plunger pump leaks externally?

A: External leakage also requires checking seals, accessories or connections and repairing or replacing them. ‌‌

Q: ‌What should I do if the plunger pump vibrates too much?

A: Excessive vibration may be caused by misalignment, unbalanced load, worn bearings or damaged pump components. You need to check and adjust the alignment, balance the load, replace worn bearings or repair damaged components. ‌

Q: ‌What should I do if the plunger pump is severely worn?

A: Wear is caused by the continuous movement of the plunger and other internal parts. Wear parts need to be checked and replaced, and lubrication conditions need to be improved to extend the service life of the pump. ‌

Q: ‌What should I do if the plunger pump seals and gaskets fail?

A: Failure of seals and gaskets may cause internal and external leakage. Damaged seals and gaskets need to be checked and replaced. ‌

Q: ‌What should I do if the plunger pump hydraulic oil is contaminated?

A: Contaminants such as dirt and debris in the hydraulic oil will affect the performance and life of the pump. The hydraulic oil needs to be replaced regularly and the hydraulic system needs to be kept clean. ‌

Q: ‌How to clean the plunger pump?

A: When cleaning, avoid collisions between the components, use a verified cleaning fluid such as WFI for cleaning, and pay attention to the cleaning temperature. ‌

Q: ‌How to sterilize the plunger pump?

A: The sterilization method needs to be selected according to the specific use environment and requirements to ensure the sterility of the pump. ‌

Q: ‌What should I do if the plunger pump suction line is blocked?

A: The suction line is usually blocked because the filter is blocked by contaminants, and the filter needs to be checked and cleaned. ‌

Q: What should I do if the oil level in the hydraulic oil tank of the plunger pump is too low‌?

A: If the oil level in the hydraulic oil tank is too low, the pump may inhale air or fail to inhale enough hydraulic oil. You need to add enough hydraulic oil and keep the oil level within the normal range.‌
