A mounting base for preventing heat expansion and contraction of pump valves and its use method

Abstract

The invention discloses a mounting base for preventing thermal expansion and contraction of a pump valve, comprising a mounting base, an adjustment support base, a pump base, a longitudinal fixing base, a transverse fixing base, a first adjusting shell and a second adjusting shell, the mounting base The first connecting ears are installed at the four corners of the top, and the adjustment support seat is installed above the installation seat; the present invention can cooperate with the telescopic and rotation of the hydraulic cylinder to complete the adjustment of the levelness of the adjustment support seat. When the adjustment is completed, the pointing piece on the turning nail Vertical to the adjustment support seat, the pump valve can be installed regardless of the horizontality of the installation base, and the pump valve is guaranteed to work in a horizontal state. The first tension sensor senses the change of the tensile force between the pump seat and the longitudinal fixed seat. Sensing the change of the tensile force between the pump seat and the lateral fixed seat through the second tensile force sensor, the shrinkage of the tensile force is the thermal expansion of the pump valve, and the increase of the tensile force is the cold contraction of the pump valve, and the thermal expansion of the pump valve Cold shrinkage for precise judgment.

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
