Slurry pump mechanical sealing and cooling device

Abstract

The invention relates to the mechanical field, in particular to a mechanical seal cooling device for a slurry pump. It includes the upper cover of the water tank, the cooling water inlet pipe, the water tank body, the cooling water outlet pipe, the pump fixing frame, the slurry pump and the mechanical sealing device. The upper end of the water tank body is provided with the water tank upper cover, and the lower end is connected with the cooling water outlet pipe One end, the side wall of the water tank is connected with one end of the cooling water inlet pipe; the slurry pump is connected with the mechanical seal device, and the water tank is fixedly connected to the slurry pump through the pump fixing frame, so The other end of the cooling water outlet pipe and the other end of the cooling water inlet pipe are both fixedly connected to the mechanical seal device. The beneficial effects of the invention are: no need to prepare external water sources, no need to arrange pipelines, limited to the place of use, the problem that clean water sources are not easy to find, and greatly save water resources.

Description

technical field [0001] The invention relates to the mechanical field, in particular to a mechanical seal cooling device for a slurry pump. Background technique [0002] Slurry pump is a kind of liquid conveying equipment, mainly used in coal, electric power, metallurgy, non-ferrous metals, power plant ash removal, mining, municipal engineering, pipeline transportation, petrochemical, salt mining engineering and construction industries. transport of fluids. The shaft seal of the slurry pump is divided into packing seal, mechanical seal and dry seal. In the case of transporting strong acid and strong alkali corrosion slurry, mechanical seals are generally used. According to the mechanical seal structure, the moving ring and the static ring will rub for a long time to generate heat, and it is necessary to add clean cooling water to cool down. In common cases, customers need to prepare external water sources by themselves. , pipelines are arranged, and each pump is controlled ...

AI Technical Summary

Problems solved by technology

In the case of transporting strong acid and strong alkali corrosion slurry, mechanical seals are generally used. According to the mechanical seal structure, the moving ring and the static ring will rub for a long time to generate heat, and clean cooling water is required to cool down. In common cases, customers need to prepare external water sources by themselves. , pipelines are arranged, each pump is controlled by valves, but due to the limited use of slurry pumps, it is not easy to find clean water sources, and the waste of cooling water is also quite alarming

Therefore, the use of mechanical seals for slurry pumps is limited
