A new test device for mechanical seal

A new test device for mechanical seal is developed. In the device, the pressure of the spring can be controlled and the vibration can be measured. The device is composed of mechanical system and computer data collection system. The mechanical system is composed of testing mechanical assembly, hydraulic loading pump station, pressure increasing and holding device for tested media, and sensors. The computer data collection system is composed of collection circuits of temperature, rotation speed of the motor, vibrating ranges, pressure of the media, leakage, torque and spring force, serial communication controlling circuit and combined power supply. The device can be used to measure the spring pressure under dynamic conditions and analyze the influence of vibration on the mechanical seal, and can be used to provide static test and working test for mechanical seals.
