Bearing box of slime pump

Abstract

The invention provides a bearing box of a slime pump. By the adoption of the bearing box of the slime pump, the problem that a sealing device of a bearing box of an existing 3PN slime pump is poor in sealing effect is solved. The bearing box of the slime pump comprises a cylindrical left shell and a cylindrical right shell. A first sealing structure which makes the right shell be connected with a main shaft in a sealed mode is arranged in the right shell. An annular groove is formed in the end face, close to the left shell, of the right shell. The inner end of the left shell is cylindrical and is connected into the annular groove in an inserted mode. A second sealing structure which makes the left shell and the right shell be connected in a sealed mode is arranged between the left shell and the right shell. The outer end of the left shell stretches out of the annular groove, and an annular shoulder is arranged on the outer side wall of the outer end of the left shell. The annular shoulder is fixedly connected with the right shell through a plurality of screws. A bearing is fixed in the left shell. The bearing, the left shell and the right shell share the same center line. The bearing box of the slime pump has the advantages of being good in sealing effect and stable in work.

Description

technical field [0001] The invention relates to a mud pump, in particular to a mud pump bearing box. Background technique [0002] The mud pump is a commonly used machine in the foundation construction process. It transports mud or circulates mud during the pile foundation hole forming process, and plays the role of wall protection, cooling, and slag removal. 3PN mud pump is a kind of mud pump that is widely used in construction. It sucks the mud from the mud pool into the volute through the high-speed rotation of the turbine, and throws the sucked mud out through the mud pipe through the centrifugal force of the turbine. into the hole. Therefore, it has the advantages of high efficacy, easy operation and large flow. [0003] The type mud pump is generally installed vertically, supported by a tripod, and suspended on the mud pool by a chain hoist. During the construction process, the liquid level of the mud tank changes with the depth of the hole. Therefore, the operator ...

AI Technical Summary

Problems solved by technology

When the mud pump is moving, it is manually controlled, which may cause the connection between the bearing box and the packing sealing device to be located below the mud surface, so that the mud quickly invades the bearing box through the joint between the two, causing the bearing damage, making the mud pump unable to operate normally
