Nowadays, ships have become a more popular means of transportation, and overseas trade is prevalent, which promotes exchanges and trade between sailings and promotes economic development. In recent years, ships have developed rapidly, and related supporting facilities have also been developed. For example, pressure water tanks are an important one, and pressure water tanks are of great help to the water supply on board.
The production and application of pressure water tanks make the water supply system on board no longer a problem. The pressurized water tank supplies the water supply system for potable water, wash water, clean water for flushing and overboard water on board.
A pressure water tank is a closed container. When the water supply to the pump is greater than the water consumption, the excess water enters the tank. The rise of the water level compresses the air in the upper space, and the water pressure of the entire water supply pipeline also gradually increases. When the pressure reaches (30~40)x104Pa, the pressure relay acts on the pressure relay through the pressure transmission tube, so that the motor is powered off and the water pump stops 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 connected to the circuit again, the motor works, and the water pump starts to supply water again.
The application of pressure water tank not only solves the problem of water use on board, but also saves electricity. The pressure water tank water supply equipment is heavy and light, occupies a small area, and can be installed in any lower part. It can be automatically controlled, save energy and reduce emissions. It has become an important equipment used by modern medium and small passenger ships and cargo ships.
