Description

Full-automatic marine pressure water tank system

Technical Field

The utility model relates to a water supply technical field specifically indicates a full-automatic marine pressure water tank system.

Background

The pressure water tank is a closed container. When the water supply amount for the water pump is larger than the water consumption amount, the redundant water enters the water tank. In modern ships, a pressure water tank is one of important water supply devices to provide pressure water for pipelines of domestic water, technical water and the like required by the ships. When in use, the pressure water tank extracts the stored water or seawater or river water, and supplies the water to each water consumption position after pressurization. With the popularity of the use of pressurized water tanks, some problems and disadvantages are gradually discovered:

1. when the pressure water tank works normally, a proper amount of gas needs to be stored in the water tank for stabilizing water pressure, so that the pressure water tank has an inflation process in the use process, but the inflation process of the traditional pressure water tank is manually operated. Meanwhile, in the working process of the pressure water tank, the air in the water tank is gradually reduced due to the fact that the air is partially dissolved in water or leaks and the like, the water level gradually rises, and then the water pump needs to be started frequently. Not only easily damage important parts such as a motor, a control contactor, a pressure controller and the like, but also greatly increase the energy loss. During the aeration process, the operator is also required to frequently check the water line within the pressure water tank. The pressure water tank needs to be manually supplemented with water and air no matter put into use for the first time or after the pressure water tank is overhauled and cleaned every time, so that the workload of operators is increased, and higher requirements on the technical and experience aspects of the operators are provided. Meanwhile, the inflation process completely depends on manual operation, and both the liquid level and the air volume cannot be effectively controlled.

2. The pressure water tank is a pressure container and must be provided with a safety pressure relief device so as to relieve redundant pressure when the pressure in the pressure water tank is too high to ensure water safety. A spring safety valve is mostly adopted in a traditional pressure water tank, and due to the instability of the liquid level and the gas amount in the step 1, the discharged medium is not unique and the discharge state is variable during pressure relief, so that the actual benefit of the safety valve is greatly reduced, and the tripping and the closing are unstable. At present, spring safety valves on the market are mainly controlled to be opened and closed by springs, are not high in sensitivity and not very stable, cannot well adapt to the variable states, and lead to high damage rate or high failure rate of the safety valves. Even the relief valve in time lets out pressure, also can not in time prevent the unusual rising of pressure in the pressure water tank effectively, make the relief valve appear frequently taking off in the short time, this makes originally unstable mechanical safety valve burden heavier for the water becomes no longer safe.

3. The pressure water tank is provided with an access door so as to clean or overhaul the interior of the water tank regularly. But traditional pressure water tank forms the negative pressure in the water tank under the condition of bottom blowoff valve pressure release to zero pressure, leads to the unable discharge of water, need disassemble the top accessory and just can make the drainage resume normal. This not only violates safe operating regulations, but also easily causes damage to the tightness of the fittings or interfaces, thereby accelerating the loss of air inside the cabinet.

4. Pressure water tank all is furnished with two water pumps, one with one and be equipped with, under a water pump overload's the condition, changeable another water pump continues to supply water, nevertheless this operation tradition pressure water tank relies on artifical manual completion completely, can't in time switch over to another water pump under one of them water pump overload's the condition and continue to supply water, has not only reduced water supply efficiency but also increased crewman's work load.

5. The pressure water tank has various faults, the existing pressure water tank has incomplete alarm points, fuzzy alarm and weak prompting property, so that a crew cannot find the fault in time and accurately judge the fault point, and the control circuit cannot be quickly and effectively closed when the fault occurs, thereby easily causing secondary damage.

6. The inside epoxy anticorrosive coating that scribbles of current water tank for reinforcing water tank body corrosion resistance, nevertheless lead to paint and domestic water or drinking water direct contact even, harmful substance such as formaldehyde in the paint can cause the pollution to being used for drinking water or domestic water, and long-term use can influence the crew healthy.
