Product Description

A hydraulic pump station, also revered as a hydraulic station, intricately operates by harnessing the power of its motor to set the oil pump into motion. This ingenious mechanism
draws oil from the reservoir and expertly propels it outward, transforming mechanical energy into the impressive pressure energy of hydraulic oil. The direction of this energy
is elegantly orchestrated by a hydraulic valve through an integrated block (or a sophisticated valve combination), allowing seamless control over pressure and flow. These parameters are
then adeptly conveyed to the hydraulic cylinder or oil motor, becoming the essential force that governs the hydraulic machinery's motion. Through external piping, the system
regulates the direction, force, and speed of the hydraulic motor, empowering various hydraulic machineries to perform with precision. Initiating the oil pump motor in this
hydraulic station, akin to the choreography of other machinery, begins with a no-load (unloading) start, followed by a brief pause, before gracefully transitioning to a load-bearing
operation. Frequent start-stop cycles are discouraged, particularly in low-temperature conditions. The overflow valve is adjusted to half, and the motor is jogged repeatedly to heat
the hydraulic oil, allowing the temperature to rise to a welcoming 20 ºC before resuming normal operations. The hydraulic pump station's wiring and external control lines converge
at the electrical box, requiring meticulous attention to the motor's rotation direction, ensuring it aligns with the pump's directional arrow. The solenoid valve's control voltage
is crucial, with AC solenoids typically operating at 220 V and DC solenoids at 24 V, mirroring the solenoid nameplate. For those with memory elements, brief energization is advised,
mirroring the intricacies of a miniature hydraulic station. Optimal performance is achieved with 32# and 46# anti-wear hydraulic oil, maintaining the oil temperature between
30-55 ºC. Extreme temperatures, below 15 ºC or above 60 ºC, deter operation, necessitating proactive heating or cooling. Routine oil changes, every 1 to 6 months, coupled with
thorough cleaning of the oil tank, ensure purity and prolonged service. In hydraulic transmission, uncontaminated oil is paramount, as impurities can adhere to the filter, escalate
noise, and shorten pump life. Consequently, regular oil maintenance is imperative. Changsha Lizheng Engineering Machinery Co., Ltd. excels as a hydraulic system artisan, dedicating
