Nowadays, ships have become a popular means of transportation, and overseas trade is popular, which promotes the exchange and trade between seafarers and promotes the development of economy. In recent years, ships develop rapidly, and related supporting facilities have also been developed, such as pressure water tank is an important one, and pressure water tank is of great help to the water supply on the ship.
The production and application of pressure water tank make the water supply system on board no longer a problem. The pressure tank supplies the ship's water supply system for drinking, washing, flushing and outboard water.
A pressure water tank is a closed container. When the water supply for the pump exceeds the water consumption, the excess water enters the water tank. As the water level rises, it compresses the air in the upper space, and the water pressure increases throughout the supply line. When the pressure reaches (30~40) x104Pa, the pressure relay is acted on through the pressure transfer tube to make the motor power off and the water pump stop working. With the consumption of water, the water level in the pressure water tank drops. When the pressure drops to (15-20) x104Pa, the pressure relay is switched on again, the motor works, and the pump starts to supply water again.
The application of pressure water tank not only solves the water problem on board, but also saves electricity. Pressure water tank water supply equipment is heavy, light, small area, can be set in any lower part, can automatically control, energy saving and emission reduction, has become an important equipment used by modern medium and small passenger ships and cargo ships.
