Abstract

The invention discloses a mud pump air case scanning and detecting device based on a magnetic memory effect. The air case scanning and detecting device comprises a stretchable stand column, a transverse movable detecting arm, a detecting probe mechanism, a rotary chassis mechanism for bearing an air case, and a data collection and control system, wherein the transverse movable detecting arm is arranged at the upper end of the stretchable stand column; the detecting probe mechanism is arc-bent-shaped; one end of the detecting probe mechanism is connected with a movable platform arranged on the transverse movable detecting arm; the detecting probe mechanism is used for carrying out magnetic memory detection on the air case; the rotary chassis mechanism is arranged below the detecting probe mechanism; and the data collection and control system is arranged on the stretchable stand column, and is used for collecting air case magnetic memory signals detected by the detecting probe mechanism and controlling the transverse movable detecting arm and the rotary chassis mechanism to move. The air case scanning and detecting device provided by the invention can be used for detecting the air case of a mud pump, identifying the stress concentration position and degree, judging whether a delivery condition exists or not, and prolonging the service life of the air case of the mud pump.

Description

technical field [0001] The invention relates to a non-destructive detection device, in particular to a mud pump air bag scanning detection device based on magnetic memory effect, which belongs to the technical field of non-destructive detection and is mainly used for damage detection of mud pump air bag casing castings before leaving the factory. Background technique [0002] In the field of petroleum industry, the air bag is an important part of the mud pump pressure system. It uses the compressibility and expansion of the air in the air bag to store (or release) the part of the liquid that is more (or less) than the average flow rate, thereby eliminating And weaken the pressure pulsation generated in the system, improve the performance and life of the mud pump. The suction and discharge process of the liquid medium in the mud pump is carried out alternately, so that alternating loads are generated in the air bag, and the alternating load under high pressure is likely to ca...
