GEHO and method for mounting inlet valve chamber thereof

Abstract

The invention discloses a method for mounting an inlet valve chamber of a GEHO. The method is characterized in that: a valve chamber outlet (4) of the inlet valve chamber (1) is connected to a diaphragm chamber (8) of the GEHO through a 90-degree bent pipe (7), so that the diaphragm chamber (8) and the inlet valve chamber (1) are not arranged in a vertical line but in horizontal connection; and an end cap (5) is arranged on an upper part of the inlet valve chamber (1) in a vertical direction, and screws (6) for fixing the end cap are also arranged on the end cap (5) in the vertical direction.Compared with the conventional mounting mode of the end cap of the inlet valve chamber, the mounting mode makes the four threaded rods for fixing the end cap of the inlet valve chamber vertically arranged, and the threaded rods are not stressed in the different directions, namely the threaded rods are stressed in the same direction, so that the problem that the threaded rods are broken can be solved, and the huge potential safety hazard of jetting slurry caused by the broken threaded rods is removed.

Description

Technical field [0001] The invention belongs to the field of propeller pipeline transportation, and particularly relates to a Qihao pump and an installation method for its inlet valve chamber. Background technique [0002] In the current slurry pipeline transportation, the pressurizing equipment used is the Qihao TZPM 1600 main pump. The inlet valve chamber cover of the main pump is installed horizontally on the side of the inlet valve chamber along the horizontal movement direction. ,Such as figure 1 As shown, the end cap 5 and the screw 6 of the fixed end cap are installed on the front of the valve chamber 1, and they are also installed horizontally. This installation method directly causes the screw 6 to bear two different forces in the horizontal and vertical directions, namely the main During the operation of the pump, the screw bears a pressure higher than 200KG in the horizontal direction from the slurry in the valve chamber 3 to the end cover 5 when the piston is pushed f...

AI Technical Summary

Problems solved by technology

Since the two different pressures are not in the same direction, but form an included angle of 90°, under the action of these two forces, the final result is that the service life of the four screw rods 6 is greatly reduced, and fractures often occur. When the screw 6 breaks, the slurry in the chamber 3 of the valve chamber will be sprayed out, forming a huge safety hazard
