Product Description

A hydraulic pump station, often esteemed as the heart of hydraulic operations, functions with seamless precision: the motor sets the oil pump in motion, igniting a transformative process.
It expertly draws oil into the pump, where it's skillfully converted from mechanical energy into potent hydraulic pressure energy. The course of flow is ingeniously
orchestrated by a hydraulic valve through a sophisticated integrated block (or valve combination), allowing for meticulous adjustments of pressure and flow. This controlled
dynamic is then transferred with elegance to the hydraulic cylinder or oil motor within the machinery via an external pipeline, thereby intricately regulating
the direction, exertion, and swift movement of the hydraulic motor, empowering a diverse range of hydraulic machinery to perform with finesse. Starting the oil pump motor
in a hydraulic pump station mirrors other machinery's operation, necessitating an initial no-load start-up (unloading), followed by a brief stabilization, before the motor takes on full load.
Avoid frequent starting and stopping to ensure operational integrity. In chilling conditions, set the overflow valve to 1/2, then jog the motor to let the overflow valve work,
thereby warming up the hydraulic oil. Once the warmth reaches a cozy 20 ºC, it's ready for regular operation. The hydraulic pump station's wiring and external
control lines are carefully housed in the electrical box. Special attention is vital to ensure the motor's rotational direction aligns with the oil pump's arrow marking.
The solenoid valve's control voltage: Typically, the AC solenoid operates at~220 V, and the DC solenoid at 24 V, both requiring strict adherence to the solenoid's nameplate.
Electromagnetic valves with memory should only be briefly energized, similar to miniature hydraulic stations. The recommended hydraulic oil types include 32 # and 46 # anti-wear oils.
Optimal oil temperature ranges between 30-55 ºC. It's crucial to avoid operation if the oil temperature dips below 15 ºC or exceeds 60 ºC. Pre-heating or cooling adjusts temperature.
Hydraulic oil should undergo a rejuvenating replacement every 1 to 6 months, accompanied by a thorough cleaning of the oil tank to banish dirt and dust.
The hallmark of hydraulic transmission is pristine oil; contaminated oil invites trouble, clogs filters, elevates noise, and shortens the pump's lifespan. Consistent cleanliness is key.
