Problems solved by technology
In some fields, diagnostic technologies with their own characteristics have been preliminarily formed, and many condition monitoring and fault diagnosis products have also been formed. The research and development of fault diagnosis systems for mechanical equipment are mainly concentrated in college tests, and less in engineering applications.

Embodiment Construction
[0040] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0041] Such as figure 1 A method for detecting a failure of a pump set is shown, which is characterized in that it includes the following steps:
[0042] 1. Collect the inlet flow F of the pump group, the pressure P1 at the pump group inlet, the pressure P2 at the pump group outlet, collect the vibration V1 of the pump group inlet flange 10, the vibration V2 of the pump group outlet flange 9, and the vibration of the pump body 1 V3, the vibration V4 of the coupling 2, the vibration V5 of the motor lower bearing 3, the vibration V6 of the motor casing, the vibration V7, V8 and V9 of the pump unit foot 8, the temperature T1 of the motor lower bearing 3, the motor upper bearing The temperature T2 of 6, the temperature T3 of the coupling 2, and the speed S of the motor spindle 5 are collected;
[0043] 2. Judging whether the collected flow, press...

The invention discloses a pump set fault detecting method. A well mouth flow F of a pump set, an inlet pressure P1 of the pump set and an outlet pressure P2 of the pump set are acquired; vibration V1of a pump set inlet flange, vibration V2 of a pump set outlet flange, vibration of a pump body, vibration V4 of a coupling, vibration V5 of a motor bearing, vibration V6 of a motor shell and vibrations V7, V8 and V9 of pump set machine feet are acquired; a temperature T1 of a motor lower bearing, a temperature T2 of a motor upper bearing and a temperature T3 of the coupling are acquired; and a rotating speed S of a motor main shaft is acquired. The method is not dependent on the design experiences, so that the method is more convenient; the method is simple in arrangement and accurate in faultdiagnosis; and a special pump set design system is built, and the pump set design is optimized, so that designed parameters are more accurate.
Description
technical field [0001] The invention belongs to the technical field of pump group fault detection, and in particular relates to a detection method for pump group faults. Background technique [0002] Compared with developed countries, the research on fault diagnosis in my country started relatively late, starting in the late 1970s. In some fields, diagnostic technologies with their own characteristics have been preliminarily formed. At the same time, many condition monitoring and fault diagnosis products have been formed. The development of fault diagnosis systems for mechanical equipment is mainly concentrated in university tests, and less in engineering applications. Contents of the invention [0003] In order to overcome the shortcomings of the above-mentioned prior art, the present invention provides a pump set failure detection method, which has simple layout and accurate fault diagnosis; it can establish a dedicated system and optimize the design of the pump set, so ...
