Product Description

A hydraulic pump station, elegantly known as a hydraulic station, functions by the motor initiating the pump's rotation, creating a mechanical marvel.
The system expertly absorbs and pumps oil, transforming mechanical energy into the powerful pressure energy of hydraulic oil, orchestrating an impressive symphony of technology.
With masterful precision, the direction is artfully controlled by a hydraulic valve through an integrated block (or valve combination), with pressure and flow finely tuned to perfection.
This precision-engineered pressure and flow travel directly to the hydraulic cylinder or oil motor, ensuring the machinery performs with impeccable control and exactitude.
The hydraulic motor's direction, force, and speed are orchestrated to drive a variety of hydraulic machines, demonstrating the peak of operational excellence.
In starting the oil pump motor, akin to other advanced machinery, an initiation with no load (unloading) is essential, followed by a brief waiting period before the load is applied for optimal performance.
It's advisable to avoid frequent motor start-stops during operation. At low temperatures, adjust the overflow valve to 1/2 and perform repeated jogs to heat the system effectively.
By carefully adjusting, the system heats until reaching an optimal temperature of 20 ºC, ensuring the smooth transition to regular operations.
Intricate wiring connects the hydraulic pump station to an external electrical control line, all culminating in a well-organized electrical box.
A keen focus on the motor's rotation direction is paramount, aligning perfectly with the arrow on the oil pump for seamless functionality.
Regarding solenoid valve control voltage, typically the AC solenoid is~220 V and the DC solenoid is 24 V. Match the control voltage with the solenoid's nameplate for flawless operation.
Electromagnetic valves with memory components should be briefly powered. For hydraulic pump stations, 32 # and 46 # anti-wear hydraulic oil is ideal, ensuring enduring performance.
The optimal oil temperature range is 30-55 ºC. Operation is prohibited below 15 ºC or above 60 ºC, demanding pre-heating or cooling for temperature regulation.
Regular hydraulic oil replacement is crucial, ideally every 1 to 6 months, alongside comprehensive tank cleaning to maintain peak condition.
Clean oil is paramount to hydraulic transmission efficiency. Deteriorated oil can result in noise and reduced pump life, necessitating consistent oil cleanliness.
