variable displacement axial piston pumps

China Highland hydraulic pump

Applications:

Concrete mixers, mining machinery, vehicles , industrial , rollers , pavers , stabilized soil mixing machine,

concrete pumps pharmaceutical machinery.

Product description :

The product from the U.S. Department of HIGHLAND  company introduced the 20 series hydraulic

transmission technology and manufacturing, 20 Series variable piston pump swash plate

structure has changed traffic. For closed -loop hydrostatic drive system . The pump is a

charge pump with variable displacement pump , the motor is a quantitative variable motor with integrated

motor or valve block. Variable control manual (MDC) hydraulic (HDC) and electric (EDC) controls, effectively

control the flow of oil output , direction and power . Pump output flow is proportional to the spindle speed

and displacement .

Displacement of variable , depending on the inclination of the swash plate , and can regulate between zero

to maximum . The output flow of the pump swash plate angle by changing the sign ( i.e., both sides of the

median ) and changed, but must transition through the swash plate position . This series of pumps - wide

speed range of hydraulic gear motors composed ,reliable, easy to operate , in supporting the production of

concrete delivery tanker , has been widely used .

PV20 Series variable piston pump features:

1,20 series axial variable piston pump manufacturing quality , simple operation

2 , the spindle bearings are tapered Gunzi bearings can withstand greater external axial force

3 , additional pumps can be connected in series

4, mechanical manipulation, to control the hydraulic servo can keep the displacement angle of the swash

plate and the corresponding displacement

5 , the control lever is released , the swash plate is automatically returned to the neutral position, the flow

becomes zero

6 , good spindle seal, even at high temperature environment of the housing pressure does not leak

7 , can be connected to the servo valve function regulator and remote control systems

 8 , the formation of the plunger for easy maintenance , the use of standard tools can be removable, so the

parts and components are pass
