The double acting hydraulic power unit works as follows: The motor drives the oil pump to rotate. The pump sucks oil from the reservoir and then discharges it, converting mechanical energy into the pressure energy of the hydraulic oil. The hydraulic oil flows through the integrated block (or valve combination) and the hydraulic valve, which adjust the direction, pressure, and flow rate. Through external pipelines, the hydraulic oil transmits to hydraulic machinery cylinders or oil motors. This controls the direction, magnitude, and speed of the liquid’s motive force, thereby driving various types of hydraulic machinery to perform work.
Double acting hydraulic power unit oil pump motor start and other machinery, the requirements of no-load (unloading) start, to be a short period of operation, and then loaded work, in general, the work process should not be frequent start, close the motor. In low-temperature startup, first, adjust the relief valve to 1/2 of the rated pressure. Next, repeatedly start the motor to allow the relief valve to overflow fully. This process will heat the hydraulic oil until the temperature rises to about 20 ℃. Once the temperature reaches this level, proceed to normal operation. (If there is a heater, it can be heated directly to raise the temperature).
Hydraulic station wiring
The hydraulic station’s external electrical control line is introduced through the electrical box. Please pay special attention to ensure that the motor’s steering matches the direction indicated by the arrow on the oil pump. For solenoid valves with memory elements should be energised for a short period of time. Such as double acting hydraulic power unit.
Hydraulic pump station oil matters
hydraulic pump station recommended 32 # and 46 # anti-wear hydraulic oil. Hydraulic station oil matters
Hydraulic station recommended 32 # and 46 # anti-wear hydraulic oil. The suitable oil temperature ranges from 30 to 55 ℃. When the oil temperature drops below 15 ℃ or exceeds 60 ℃, you should avoid operation. To adjust the oil temperature, you can heat or cool the oil beforehand. Generally, you should replace hydraulic oil every 1 to 6 months and clean the oil tank, removing dirt and dust. Hydraulic transmission must avoid using dirty and deteriorated oil. Otherwise, dust can accumulate in the suction filter, leading to increased noise. This can reduce the pump’s lifespan. Therefore, it is essential to keep the oil clean regularly.
