Mounting base for preventing heat expansion and cold contraction of pump valve and using method thereof

Abstract

The invention discloses a mounting base for preventing heat expansion and cold contraction of a pump valve. The mounting base comprises a mounting base, an adjusting support base, a pump base, a longitudinal fixing base, a transverse fixing base, a first regulating shell and a second regulating shell; and the four corners of the top of the mounting base are provided with first connecting lugs, andthe adjusting support base is installed above the mounting base. The mounting base can telescopically cooperate with a hydraulic cylinder to rotate to adjust the levelness of the adjusting support base, after adjustment is completed, a pointing piece on a rotating nail is perpendicular to the adjusting support base, the pump valve can be installed regardless of the levelness of an installation base surface, and it is ensured that the pump valve works in a horizontal state. A first tensile force sensor senses the change of the tensile force between the pump base and the longitudinal fixing base, a second tensile force sensor senses the change in the tensile force between the pump base and the transverse fixing base, the decrease of the tensile force refers to heat expansion of the pump valve, the increase of the tensile force refers to cold contraction of the pump valve, and accurate judgment is made for heat expansion and cold contraction of the pump valve.

Description

technical field [0001] The invention relates to the field of installation equipment for pump valves, in particular to a mounting base for preventing heat expansion and contraction of pump valves and a method for using the same. Background technique [0002] A pump valve is a machine that transfers or pressurizes a fluid. It transmits the mechanical energy of the prime mover or other external energy to the liquid to increase the energy of the liquid. The pump is mainly used to transport liquids such as water, oil, acid and alkali, emulsion, suspoemulsion and liquid metal, and can also transport liquid and gas mixtures. and liquids containing suspended solids; the installation base is a device for installing and fixing the pump valve. [0003] During the installation process of the existing pump valve, the installation of the pump valve needs to be ensured in a horizontal state, otherwise it will greatly affect the normal use of the pump valve, and the use of the non-horizont...

Problems solved by technology

[0004] The purpose of the present invention is to provide a mounting base for preventing thermal expansion and contraction of pump valves and its use method. In order to overcome the above-mentioned existing pump valves in the installation process, the installation of pump valves needs to be ensured in a horizontal state, otherwise it will greatly affect the The normal use of the pump valve and the use in a non-horizontal state will greatly reduce the service life of the pump valve; at the same time, when the pump valve is in use, it will cause thermal expansion and contraction of the pump body due to the temperature of the outside world and the temperature of the transmission fluid, and the heat and cold The pump is deformed due to contraction, resulting in the displacement of the transmission shaft and the displacement of the connection with the pipeline; and the change of the thermal expansion and contraction of the pump valve is small, which needs to be detected and adjusted in a special way, otherwise the adjustment of the thermal expansion and cold contraction of the pump valve cannot be realized. technical issues
