Sealing piece provided with hidden type lateral fastening device and used for pump

Abstract

The invention relates to the technical field of pump seals, in particular to a pump seal with a hidden lateral fastening device, which includes an annular main seal block, a left seal connector is arranged on the left side of the main seal block, and the main seal A right sealing joint is arranged on the right side of the block. A pump seal with a hidden lateral fastening device of the present invention sets an adjustment bracket controlled by an adjustment gear rod inside the main seal block, controls the telescopic rod inside the telescopic hole through the adjustment bracket, and inserts the locking hole into the locking hole. To control the loading and unloading of the main sealing block and the sealing joints on both sides, so that there is no need to set up additional fixing brackets outside the entire seal, reducing the external volume, and using the sealing slope on the sealing strip to improve the sealing and safety. At the same time, through the split type Setting can greatly facilitate the pre-production and post-maintenance.

Description

technical field [0001] The invention relates to the technical field of pump seals, in particular to a pump seal with a hidden lateral fastening device. Background technique [0002] Water pumps used in many fields. Among them, submersible pumps and semi-submersible pumps are widely used. If the pump has a submersible function, it needs to have good sealing characteristics. The sealing characteristics of the water pump play an extremely important role in good working performance. In traditional submersible pumps, Waterproof seals need to be installed, but the current waterproof seals on the market are simple in structure, and the external assembly mechanism is mainly used to connect and fix the seals and connectors, resulting in a large external volume, and the external assembly mechanism has been exposed for a long time. and limited firmness. Contents of the invention [0003] The technical problem to be solved by the present invention is: in order to solve the problems ...
