SQB-type Diaphragm Automatic Air Pressure Water Supply Equipment
Overview:
Diaphragm-type air pressure water supply equipment is a new type of water supply equipment that has emerged in recent years in China. It consists of a diaphragm-type air pressure expansion tank, water pump, automatic control cabinet, pipelines, valves, instruments, etc. The product has reasonable structure, sophisticated technology, reliable quality, excellent performance, and low price, making it an indispensable equipment in water supply and drainage engineering.
Performance Features:
Energy-saving, prolonging the service life of water pumps. The diaphragm-type airbag can store energy. During low water consumption periods, the water pump does not need to start for a long time, saving electrical energy and extending the service life of the water pump.
The water supply pressure can be arbitrarily set to ensure the water supply pressure for users.
Simple installation and construction, shortening the construction period.
One-time inflation ensures long-term use without gas leakage.
Can replace elevated water tanks and water towers, reducing investment.
Water is not easily contaminated in a closed container.
Long service life of rubber diaphragm.
Fully automatic control, reliable operation, and convenient.
Working Principle:
According to Boyle's Law, the product of pressure and volume of a certain mass of gas at a certain temperature is constant. When the water pump is working, excess water enters the air pressure water tank while water is delivered to the water supply pipeline. The water chamber expands and compresses the gas in the tank. As the air chamber contracts, the pressure inside the tank increases. When the pressure rises to the high working pressure P2, the power to the water pump is cut off by the control cabinet, and the water pump stops. At this point, the water stored in the tank is sent to the water supply pipeline using the pressure of the compressed gas in the tank. As the water chamber contracts and the air chamber expands, the pressure inside the tank decreases. When the pressure drops to the low working pressure P1, the control cabinet turns on the power to the water pump, and the water pump starts again. This cycle repeats continuously.
Instructions for Use:
The equipment should be installed horizontally.
Before leaving the factory, the product has undergone pressure tests and air chamber inflation work. Users do not need to conduct pressure tests again, and the tank body should not be disassembled at will during on-site installation to prevent injury from gas leakage or affect the sealing performance of the equipment.
The equipment room should have good ventilation conditions, and the room temperature (in winter) should not be lower than 2°C. Consider anti-freezing measures for outdoor installation.
If the debugging personnel find that the tank needs to be inflated during debugging, they should strictly follow the following operation procedures:
① The debugging procedure of the air pressure water tank should be carried out on the principle of filling water first and then filling nitrogen. During water filling, city water supply system can be used to fill water. Open the exhaust valve during water filling. When the air in the water chamber is exhausted, stop filling water and close the exhaust valve. Start inflating.
② During inflation, first press the upper and lower pointers of the electric contact pressure gauge to the required high pressure and low-pressure positions, then open the inflation valve for inflation. When the inflation pressure reaches the high-pressure P2 value, the inflation is completed, and the inflation valve is closed.
