Features double variable vane pump VHID
Double variable vane pump VHID variable vane pump consists of two sets of links into one. Double variable vane pump VHID to an electric motor directly drives. From 2 variable vane oil pump discharge can supply each individual circuit. Double variable vane pump VHID can drive actuators. Double variable vane pump VHID can drive the same actuator, its biggest strengths for the same axis can drive two variable vane pump to save space, and within the same circuit can easily get high and low pressure.

Assembly precautions of double variable vane pump VHID
1 General VHID double variable vane pump the oil to a closed subject .
2 . Motor shaft with double variable vane pump VHID axis using the coupling assembly, errors need to balance within 0.05.mm, angle error to be less than 1C °.
3 When installation double variable vane pump suction filter screen VHID recommend using 100 to 150 mesh , depending on caliber double variable vane pump VHID actual discharge volume may be, shall be higher than the bottom of the tank assembly 5 to 10 cm.
4 Recommended hydraulic oil are:
a, double variable vane pump VHID working pressure lower than 70KG/cm2, hydraulic oil viscosity 30 ~ 50cts (ISO VG32) is more suitable working conditions.
b, double variable vane pump VHID working pressure is higher than 70KG/cm2, hydraulic oil viscosity 50 ~ 70cts (ISO VG32) is more suitable working conditions.
5 double variable vane pump VHID continuous operation of the hydraulic oil temperatures should be maintained at 30 ~ 60C °, below 15C ° Please use the heater more than 60C °, please use the cooler.
6 . Reduce inhalation resistance, double variable vane pump suction VHID Do one meter high oil too .
When 7 start double variable vane pump VHID, the first note of the electric motor and twin variable vane pump VHID should turn in the same direction , so that the motor rotates slowly segmented pressure until the pressure required . 8 External drain double variable vane pump VHID , the drain line must be directly connected to the bottom of the oil , and the back pressure must not exceed 0.3kg/cm2.
