Installation structure of vertical self-priming pump on chemical tank

Abstract

The invention relates to an installation structure of a vertical self-priming pump on a chemical tank. The installation structure is characterized in that a base is installed on the vertical self-priming pump through a bolt B, an inlet special-shaped pipe penetrates through the base and is fixed on the inlet flange of the vertical self-priming pump through a bolt C and a nut B, an inlet rubber gasket is adopted for sealing between the inlet special-shaped pipe and the inlet flange of the vertical self-priming pump, the vertical self-priming pump is lifted up and installed on a tank body flange through the base, the base and the tank body flange are fixedly connected through a bolt A and a nut A, a tank body flange opening is arranged on the tank body flange and one end of the inlet special-shaped pipe stretches into liquid in a tank body. The installation structure of the vertical self-priming pump on the chemical tank has the advantages that: 1) the cost is saved, the tank body and the tank body flange are not required to be modified at all, the vertical self-priming pump is not required to be modified at all, and two simple parts, i.e. the base and the inlet special-shaped pipe are only required to be added; and 2) the installation method is simple and reliable, the entire installation can be completed as long as the base and the tank body flange are connected through the bolt and the nut, and the entire process is simple and easy to operate.

Description

technical field [0001] The invention is a vertical self-priming pump installation structure on a chemical tank. It belongs to the technical field of vertical self-priming pumps. [0002] It is a simple, effective and reliable installation method applied to the vertical self-priming pump on the tank body, especially an installation method of the vertical self-priming pump. Background technique [0003] In petroleum and chemical companies, tanks are often used to hold liquid solutions, and the pumps are used for turnover transportation. Usually, an open flange is set on the tank body. The pump uses a long-axis submerged pump, and the long-axis submerged pump is directly Installed on the open flange of the tank, the pump can work normally. However, because the pump type used is a long-axis submerged pump, the long-axis submerged pump has a short service life and is prone to metal friction. It is not explosion-proof in the solution. Now it is gradually eliminated, and a new re...

However, because the pump type used is a long-axis submerged pump, the long-axis submerged pump has a short service life and is prone to metal friction. It is not explosion-proof in the solution. Now it is gradually eliminated, and a new reliable pump type is used to replace the long-axis Submerged pump, the commonly used type of new pump type is vertical self-priming pump
