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
