Self-power supply and wireless data transmission-based mechanical seal face friction torque measurement device

Abstract

The invention provides a self-power supply and wireless data transmission-based mechanical seal face friction torque measurement device which can be used for realizing accurate measurement of torques of mechanical seals to be measured in mechanical seal performance test devices. The self-power supply and wireless data transmission-based mechanical seal face friction torque measurement device comprises a shaft sleeve, a transmission pin, a force sensor, a signal processor, a wireless transmission module, a wireless reception module and a self-power supply module, wherein a main shaft passes through the shaft sleeve; the sleeve shaft is sleeved by a mechanical seal of the face friction torque to be measured; a movable ring is connected with the shaft sleeve; a fixed ring is fixed on a seal cavity; the torque generated by face friction between the movable ring and the fixed ring of the mechanical seal is balanced with the torque transmitted to the shaft sleeve by the transmission pin through the main shaft; the torque is decided by the product of a peripheral force measured by the force sensor adhered on the transmission shaft and a force arm at a force measurement point; the measured peripheral force is processed by the signal processor and transmitted to the wireless reception module by the wireless transmission module; by utilizing the electric energy generated by rotation of the main shaft or the shaft sleeve, power can be supplied to the signal processor and the wireless transmission module through the self-power supply device.

Description

technical field

[0001] The technology belongs to the technical field of testing, and in particular relates to a test device for measuring the frictional torque of a mechanical seal end face. Background technique

[0002] The increasing shortage of resources and the continuous deterioration of the environment have put forward the production requirements of zero leakage and zero discharge for enterprises. Mechanical seal, as the main shaft seal of the moving equipment in industrial production, on the one hand provides protection for the leakage prevention of the equipment, on the other hand, due to the friction and wear of the end face, it also consumes the shaft power. For this reason, people continue to work hard to find suitable end face specific pressure and materials to reduce end face friction power consumption, prolong service life, and at the same time ensure the sealing performance of mechanical seals. However, the quality of the material matching of the sealing pair...
