Problems solved by technology

In addition, although most of the data acquisition modules of the existing oil-lubricated bearing characteristic comprehensive test benches can meet the performance requirements, neither the upper computer nor the portable data processing software can fully meet the requirements of the water-lubricated bearing system. Therefore, there is an urgent need to develop an intelligent compre

Example Embodiment

[0025] Attached figure 1 This is a specific embodiment of the present invention, and the present invention will be described in detail below in conjunction with this specific embodiment. The water-lubricated bearing comprehensive test bench of the present invention includes a drive transmission system, a mainframe housing, a bearing and its lubrication system, a loading system, a measurement system, a signal processing and analysis system, and the like. The drive transmission system includes variable frequency motor 1, elastic coupling A2, speed increasing box 3 and elastic coupling B4, etc. The main function is to provide uniform and adjustable torque for the test bench. After the frequency conversion motor of the test bench is started, the speed can be stably run at a fixed speed value through the inverter, or a speed increase gradient (or a given start time period) can be given to study the transient characteristics of the test bench.

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, in particular to an intelligent pump water-lubricated bearing test device, which is mainly used for comprehensive performance tests of pump water-lubricated bearings. Background technique [0002] Using water as the lubricating medium of the bearing has unique advantages such as 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. Therefore, it is not only used in machine tools, ships, water turbines, steam turbines, aerospace and other fields Widely used, water-lubricated bearings have been increasingly used in fuel pumps, well pumps, ...
