Embodiment Construction
[0043] The present invention will be further described by means of embodiments below in conjunction with the accompanying drawings, but the present invention is not limited to the scope of the following embodiments.
[0044] Such as figure 1 As shown, a pressure water tank device of the present invention includes a pressure water tank body 1, and the pressure water tank device also includes an air replenishment device. When the water level inside the pressure water tank body 1 reaches a set high level, the air replenishment device Air is added into the pressure water tank body 1; the air supply device stops adding air into the pressure water tank when the water level inside the pressure water tank body 1 reaches a set low level.
[0045]When the water level in the pressure water tank body 1 reaches the set high water level, air is continuously introduced into the pressure water tank body 1, and the feed water pump 3 is closed when the internal pressure exceeds the closing pres...

The invention discloses a pressure water tank device which comprises a pressure water tank body and further comprises an air supplementing device, and the air supplementing device supplements air intothe pressure water tank body when the water level in the pressure water tank body reaches a set high position. When the water level in the pressure water tank body reaches a set low level, the air supplementing device stops supplementing the air into the pressure water tank. According to the pressure water tank device disclosed by the invention, when the water level in the pressure water tank body reaches the set high water level, air is continuously introduced into the pressure water tank body; when the internal pressure exceeds the closing pressure of a water feeding pump, the water feedingpump is closed; the internal pressure is prevented from being lower than the starting pressure of the water feeding pump because air in the pressure water tank body is continuously dissolved in water; the water supply pump is prevented from being frequently started to continuously supply water into the pressure water tank body, the water level in the pressure water tank body is far higher than the set high water level, the pressure water tank body loses the energy storage function, and meanwhile the service life of the water supply pump can be prolonged.
Description
technical field [0001] The invention relates to the field of supporting equipment for ships, in particular to a pressure water tank device. Background technique [0002] In order to facilitate water use on ships, a pressure water tank system will be installed in the engine room. The existing pressure water tank generally adopts a pressure relay to control the operation of the feed water pump. When the water is supplied to the outside, the pressure in the water tank will gradually decrease. When the pressure drops below the set low pressure value, the pressure relay will start the feed water pump to The pressure water tank replenishes water. As the water level in the water tank rises, the air in the water tank is compressed to cause the pressure to rise. When the pressure rises beyond the high pressure value set by the pressure relay, the pressure relay will cut off the power supply of the water pump, and the water replenishment is over. . However, since the air in the pres...
