Everyone is familiar with hydraulic and electric pumps. It is a common hydraulic equipment. It has a pressure sensor. So many people wonder, what role does the hydraulic electric pump pressure sensor play for the pump? Follow the editor to find out!
The hydraulic electric pump pressure sensor provides protection for the normal operation of the pump. The pressure sensor is designed to be installed at the outlet of the pump. Contrary to other traditional'appear/disappear' detectors, stator temperature probes and other interfering devices, it is considered It is the most effective way to prevent the pump from interfering with the operation. The device is composed of three basic components: sensor, pressure switch and control box. This sensor is installed between two standard ANSI flanges to make the fluid passage unobstructed. The pressure detection of the entire piping system ensures that the housing, fixtures or jumpers do not affect the pressure readings. Another feature is that there is a liquid-filled pressure gauge that can visually detect the pressure in the entire pump system.
The hydraulic electric pump is composed of an electric motor, a gear pump, a valve plate seat, a buffer valve, etc. The valve plate seat is set between the oil tank and the motor, and a plug-in oil return valve, one-way valve, and safety valve are provided in the valve plate seat. , Buffer valve, the input shaft of the gear pump penetrates into the valve plate seat, and the hydraulic electric pump is connected with the output shaft of the motor through the gear shaft sleeve. A buffer valve is arranged in the vertical hole of the valve plate seat, a safety valve, a one-way valve and an oil return valve are respectively arranged in its two side holes, and a control rod is arranged on the oil return valve. When the buffer valve makes the motor start with load, the hydraulic electric oil pump plays the role of load pressure delay, so as to prevent the hydraulic electric pump motor from burning due to excessive starting current, and relieve the hydraulic shock to protect the normal operation of the motor.
