Description

Technical Field

[0001] The utility model relates to the technical field of pump body mechanical seals, in particular to a seawater desalination pump with a mechanical seal. Background Art

[0002] The mechanical seal of a seawater desalination pump is a key component to ensure its efficient and stable operation. It is mainly used to prevent seawater from invading the pump body, thereby protecting the internal parts of the pump from corrosion and wear.

[0003] Mechanical seals typically consist of a rotating ring, a stationary ring, a spring, a gland, a sleeve, and other components. The rotating and stationary rings are the core components of the seal, forming a sealing surface through mutual friction to prevent seawater leakage. However, if impurities enter the end face between the stationary and rotating rings, the friction between the two will damage the end face, causing the seal to fail. Utility Model Content

[0010] Preferably, the depth of the mounting groove is greater than the length of the connecting piece, and the movable hole is configured as an arc notch.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] The utility model inserts the connecting piece on one side of the filter into the installation groove, and inserts the other end of the filter into the embedding groove of the static ring, thereby protecting the contact surface ports of the dynamic ring and the static ring, preventing impurities from entering between the two and causing wear at the ports, thereby affecting the sealing effect;

[0013] The utility model is implemented by threading a threaded rod on one side of the mounting plate into a threaded hole. When the dynamic ring drives the filter screen to rotate, impurities on the outside of the filter screen are scraped off by a scraper at the lower part of the mounting plate, thereby preventing impurities from accumulating on the outside of the filter screen and affecting the normal rotation of the dynamic ring.
