Abstract

The invention discloses a simple photoelectric early warning device for water tank liquid level, comprising an alarm, a magnetic control plate, a positioning sleeve, a stabilizer, an installation sleeve and a float. The installation sleeve is installed at the center position of the float axis line by fastening with screws. The magnetic control plate and the positioning sleeve are positioned and installed. The magnetic control plate body is installed with a strong magnetic block. The buoy rod body is positioned with a positioning sleeve. Four stabilizers are evenly installed at the four corners of the float. The alarm is installed at the top of the buoy rod. A simple photoelectric early warning device for water tank liquid level is designed for water level alarm design. When the sealing water level decreases, the float drops. When it drops below the critical line, the magnet triggers the magnetic control switch, the circuit is closed, and the red light of the early warning indicator lights up to provide early warning. The bottom arc-shaped float ensures the overall stability when the water flow floats up and down. The side floats reduce the water flow impact when the water flow moves. The stabilizers are evenly installed at the four corners of the float to ensure the floating stability of the float.

Mechanical seals are vulnerable parts of pumps, and the price of mechanical seals is relatively high. There are three main reasons for the damage of mechanical seals: opening of the sealing surface, overheating, and out-of-tolerance. Among them, overheating is the main cause of mechanical seal damage and the main cause of other types of damage. At present, slurry pumps using mechanical seals are equipped with sealing water tanks to cool the mechanical seals and ensure that the temperature of the mechanical seals is within the normal range. Insufficient sealing water in the mechanical seal water tank will cause the mechanical seal to overheat, thereby damaging the mechanical seal. Summary of the invention
