Do not forget to check the pressure hand pump unloading. When you uninstall, slowly rotating high pressure hand pump unloading valves, hydraulic pumps, watching the pressure gauge pointer to zero is bit, the system uninstalled. Uninstall impact caused excessive damage is easy to gauge. Convinced that the system pressure is zero bits, then party detachable connection between the hydraulic lines (EHV quick connector). High pressure hand pump the pressure is high, the leak check must be carried out prior to use; the main inspection system each connector is connected and reliable, with or without leakage. That is close high pressure hand pump unloader valve, operating handle, stop the line when pressure hand pump to provide a pressure during operation, the hydraulic pump station, and then observe whether the connecting parts of pipe leakage, hand pump, watching the pressure gauge is stable. No leakage, pressure is stable, smooth operation is working properly. Hydraulic pump station _ _ Lu Lu of hydraulic force provided by the hydraulic machinery plant in Texas.
