Note for use in hydraulic systems:

1 hydraulic system oil and working conditions

Recommended the use of 32, 46 hydraulic oil. The most suitable temperature is 30-60 DEG C when no boot temperature lower than 15 DEG C or greater than 65 degrees, to adjust the temperature in advance by heater or cooler. Hydraulic oil is generally 1~6 months should be replaced once, and clean the tank, remove dirt and dust. Hydraulic transmission most avoid oil dirty, or dust paste viscosity on the oil filter, the noise is increased, the pump life is reduced, so we should always keep the oil clean, should be three months to clean the oil net once.

2 external control line and valve and valve to introduce the control voltage

The external electrical control line is introduced by the electric box, please pay special attention to the motor to be consistent with the direction of the pump.

Solenoid valve control voltage: AC solenoid is generally 220V, DC electromagnet for the 24V, must use the control voltage to be consistent with the electromagnet signs. For the solenoid valve with memory components to short power.

3 start of oil pump motor

Hydraulic station of the pump motor start and other machinery, requires no load (unloading) start, and other short moving line, and then load the work, under normal circumstances, the work process is not frequent, closed motor.

When starting at low temperature, to adjust the relief valve to the rated pressure of 1/2, and then repeated the motor, so that the overflow valve overflow, in order to give hydraulic heating, the temperature increased to 20. C or so, and then put into motion. (direct heating of the heater)
