Features:

1) Piston pump is widely used in hydraulic transmission system of machine tools, metallurgy, forging, mining and hoisting machinery, especially widely used in high-power hydraulic transmission system.

2) REXROTH vane pump is mainly used in mining, coal, metallurgy, chemical industry, environmental protection and other industries. The general meaning of sand more is used in environmental protection, dredging, dredging and other industries more. This series of sand mainly ES or G more. In addition, there are a lot of sand called type oil field SB pump, mining PS pump series and so on. This paper introduces the main pump in the usual sense of the ES or G series of dredging, the environmental protection industry in the sand.

3) REXROTH gear pump is suitable for transporting Newton liquids or non Newton liquids in petroleum, chemical industry, paint, dyestuff, food, grease, medicine and other industries, and the kinds of delivery liquids can be made from light, volatile liquids until heavy, viscous or even semi-solid liquids.

The characteristics of Rexroth piston pump:

- the axial piston of the inclined disk structure used in the hydraulic open circuit is the pump

- The flow rate is proportional to the driving speed and displacement, and the switch can realize the stepless variable by adjusting the inclination angle of the inclined disk.

-ISO standard installation flange

- flange connection conforms to SAE meter system

- two shell spillway holes

- excellent performance of inhalation

- allow continuous running pressure to reach 280Bar

- Low noise

- drive shaft can bear axial and radial load

- High power / weight ratio

- wide range of control forms

- control response time is short

- by using the through - axis structure, it can be used in multi loop system

Description:

Rexroth piston pump according to the inclination of the different elements, a swash plate and inclined shaft type two.

The inclined disk type is the inclined angle of the cylinder body with relative rotation of the inclined disc, and the plunger is reciprocating in the pump cylinder. The axis of the drive shaft is the same as the axis of the cylinder. This structure is simple, the speed is high, but the working condition is high, the contact part between the end of the plunger and the inclined plate is often the weak link.

The oblique axis of the oblique axis is the same as the axis of the drive shaft. It is the reciprocating movement of the plunger because of the angle of the cylinder block relative to the transmission shaft. The flow regulation depends on the angle of the swinging cylinder block, so some are also called the pendulum cylinder. Compared with the inclined plate, it is reliable in work, large in flow, but complex in structure.

Compared with radial piston pump, the axial piston pump has high discharge pressure. It can work in the range of 20 ~ 50MPa, and the efficiency is high. The radial size is small, compact, small and light. But the structure is more complex than the radial piston pump, and the manufacturing requirements are high and the price is more expensive.
