The invention relates to the field of liquid level alarming, in particular to a simple photoelectric early warning device for the liquid level of a water tank.

Background

Various slurry pumps are involved in the production process of a coal preparation plant, and most of the seals of the slurry pumps are mainly mechanical seals. The mechanical seal is a vulnerable part of the pump and is expensive. The mechanical seal is damaged for three main reasons: seal face opening, overheating, out of tolerance, where overheating is the primary cause of mechanical seal failure and other types of failure. At present, a slurry pump using mechanical seal is provided with a sealing water tank for cooling the mechanical seal, so that the temperature of the mechanical seal is ensured to be within a normal range. Insufficient sealing water in the mechanical sealing water tank can cause overheating of the mechanical seal, and further damage to the mechanical seal.
