Embodiment Construction

[0018] Such as figure 1 As shown, a mechanical seal pressure maintaining device includes a water tank 6. Soft water without precipitation and impurities is used in the water tank 6. The temperature is normal temperature, and the water needs to be replaced regularly. The water inlet and outlet of the mechanical seal 1 pass through the water inlet pipe 11 and The return pipe 12 is connected to both ends of the water tank 6, and a cooler 7 is installed in the water tank 6 close to the end of the return pipe 12. The cooler 7 can use circulating water as the cooling medium to cool the heat generated during the operation of the mechanical seal 1. A first one-way valve 21 , a water pump 5 and a filter are installed, and a second one-way valve 22 is installed on the return pipe 12 .

[0019] The use method of the present invention: start the water pump 5, the pressure of the water pump 5 will automatically open the first one-way valve 21, the demineralized water will fill the sealing ...

Abstract

The invention relates to a pressurizer for a mechanical seal. The pressurizer for the mechanical seal comprises a water tank, wherein a water inlet and a water outlet of the mechanical seal communicate with the two ends of the water tank through a water inlet pipe and a water return pipe respectively, and a cooler is arranged at the end, close to the water return pipe, in the water tank; a first one-way valve and a water pump are installed on the water inlet pipe, and a second one-way valve is installed on the water return pipe. The pressurizer for the mechanical seal is used for solving the problem that when an existing mechanical seal leaks, sealing oil enters a polymerization kettle and contaminates materials in the polymerization kettle.

Description

technical field [0001] The invention relates to a mechanical seal pressure maintaining device. Background technique [0002] The pressure-holding device of the mechanical seal of the polymerization kettle generally adopts an oil station, which provides pressure and lubrication to the mechanical seal through an oil pump. However, in long-term use, it is found that once the mechanical seal leaks, the sealing oil will directly enter the polymerization kettle, causing pollution to the materials in the kettle. Reduce product quality. At the same time, the sealing oil of the gas station system will experience natural loss and deterioration after a cycle, and it needs to be added and replaced regularly, which increases maintenance costs. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a mechanical seal pressure maintaining device, which is used to solve the problem that when the existing mechanical seal leaks, the seali...
