Now Xiaobian to share with you the high pressure piston pump pump sequence, as follows: High pressure piston pump pump to follow what order? 1, check the pump to start, water (gas) tank and the...
Abstract: The fault diagnosis method of hydraulic pump bearing based on integrated BP network is studied. Using the frequency domain and the inverse frequency domain for feature extraction, an integrated BP network is adopted to diagnose and identify the fault, which solves the problems of the fault feature of the hydraulic pump bearing and the difficulty of multi-fault identification. The experimental results show that the integrated BP network can effectively diagnose and identify...
In the hydraulic system, high-pressure gear pumps and hydraulic motors are energy conversion devices. It uses high-strength aluminum alloy shell, high bearing capacity DU bearing and floating side panels and other structures, with high pressure, wide speed range, simple structure, light weight, reliable, long service life and so on. The high-pressure gear pump converts the mechanical energy input by the prime mover into the hydraulic energy of the fluid oil. It belongs to the hydraulic energy...
