Method for detecting grouping location degree of multistage segmented gear pump shells

Abstract

The invention belongs to the technical field of mechanical processing, and particularly relates to a method for detecting the grouping location degree of multistage segmented gear pump shells. The method comprises the steps of respectively inserting a driving process core shaft and a driven process core shaft into a driving shaft hole and a driven shaft hole from top to bottom, detecting the grouping location degree of the driving shaft hole and the driven shaft hole in each stage of pump shell at the lower segment, wherein the location degree of each stage of pump shell of the lower segment is detected to be qualified when the driving process core shaft and the driven process core shaft can be inserted to the bottom parts of the driving shaft hole and the driven shaft hole respectively; enabling a lower-stage pump shell at an upper segment to sleeve the driving process core shaft and the driven process core shaft, wherein the location degree of the lower-stage pump shell at the upper segment is qualified if the lower-stage pump shell at the upper segment can sleeve the driving process core shaft and the driven process core shaft; and enabling an upper-stage pump shell at the upper segment to sleeve the driving process core shaft and the driven process core shaft, and fixedly installing the upper-stage pump shell at the upper segment and the lower-stage pump shell at the upper segment on a pump set shell, wherein if the upper-stage pump shell at the upper segment and the lower-stage pump shell at the upper segment can be installed in place, the location degree of the upper-stage pump shell at the upper segment is qualified. The detection method provided by the invention does not increase original processing procedures and the manufacturing difficulty of each stage of pump shell and has wide application values in the technical field of multistage pump set processing and manufacturing.

Description

[0001] 【Technical field】 [0002] The invention belongs to the field of mechanical processing technology, and in particular relates to a method for detecting group position degrees of multistage segmented gear pump casings. [0003] 【Background technique】 [0004] According to the use and maintenance of the multi-stage segmental gear pump, it was found that the wear state of the gears and casings of the various pumps after use is quite different, and some pumps even have abnormal damage that affects normal work during use. Analyzing the cause of this severe wear or abnormal damage, it is considered that the relative position of the casings of the multi-stage pump group has a great influence on the working state of the pump, and it is necessary to improve the group position of all the pump casings of the entire pump group. It is difficult to improve the processing technology and precision of pump casings at all levels, and it is necessary to find effective solutions. [0005] A...
