Classification and advantages of Rexroth hydraulic pumps

Friends of Rexroth hydraulic pumps know that Rexroth gear pumps can also be called Rexroth hydraulic pumps. Rexroth hydraulic pumps are the power components of the hydraulic system. They are driven by engines or motors and suck oil from the hydraulic tank to form pressure oil and discharge it. , a component sent to the actuator, so what are the specific classifications of Rexroth hydraulic pumps? What are the advantages of each of these products? The company's technical staff will introduce to you the classification and advantages of Rexroth hydraulic pumps as follows:

1. Classification of Rexroth hydraulic pumps:

According to whether the flow rate is adjustable, it can be divided into: variable pump and fixed pump. The output flow can be adjusted according to needs is called a variable pump, and the flow cannot be adjusted is called a fixed pump. According to the commonly used pump structures in hydraulic systems, they are divided into three types: gear pump, vane pump and plunger pump.

1. Rexroth gear pump: smaller in size, simpler in structure, less demanding on oil cleanliness, and cheaper in price; however, the pump shaft is subject to unbalanced force, severe wear and tear, and large leakage.

2. Rexroth vane pump: divided into double-acting vane pump and single-acting vane pump. This kind of pump has uniform flow, smooth operation, low noise, higher operating pressure and volumetric efficiency than the gear pump, and the structure is more complex than the gear pump.

3. Rexroth plunger pump: It has high volumetric efficiency, small leakage, can work under high pressure, and is mostly used in high-power hydraulic systems; but it has a complex structure, high requirements for materials and processing accuracy, expensive price, and high requirements for oil cleanliness.

2. Advantages of Rexroth hydraulic pumps:

1. Coaxial structure can form a combination pump;

2. The control response time is short;

3. Low noise;

4. Long life;

5. Excellent power/weight ratio;

6. Modular design;
