Abstract

The invention discloses a comprehensive test stand for water-lubricated bearings for pumps. The comprehensive test stand comprises a driving transmission system, a main box, a bearing, a lubricating system, a loading system, a measuring system, a signal analyzing and processing system and the like, the driving transmission system consists of a variable-frequency motor, an elastic coupler, a step-up box and the like, the main box is a cube with a transparent top cover plate, and a spindle horizontally enters the box from a side wall, which is close to the end of the elastic coupler, of the main box. A pressure sensor, an eddy current sensor, a vibration acceleration sensor, a temperature sensor and the like are sequentially arranged and mounted on the spindle or around the spindle and used for acquiring displacement signals, rotation speed signals, phase signals, temperature signals, pressure signals, vibration signals and the like, and the sensed signals which are acquired by the various sensors in an online manner are transmitted to an upper computer to be processed, displayed and stored. The comprehensive test stand has the unique advantages of fine performance, high precision, low cost, environmental protection, zero pollution, friction reduction, energy conservation, noise and vibration reduction, fine fire resistance, easiness in maintenance and the like.

Description

technical field

[0001] The invention belongs to the technical field of water-lubricated bearing test benches, and particularly relates to an intelligent pump water-lubricated bearing test device, which is mainly used for comprehensive performance test of pump water-lubricated bearings. Background technique

[0002] Using water as the lubricating medium for bearings has the unique advantages of low cost, environmental protection and no pollution, wear reduction and energy saving, noise reduction and vibration reduction, good flame retardancy, and easy maintenance. The use of water-lubricated bearings in mechanical equipment can not only simplify the bearing-rotor system and the structure of the whole machine, but also improve the reliability and stability of the whole machine. Widely used, water lubricated bearings have been increasingly used in fuel pumps, well pumps, canned pumps, desalination pumps, nuclear pumps and many other pump products.
