Shandong life variable frequency complete water supply equipment manufacturer provides

Description :

　　The household variable frequency water supply equipment device consists of a pressure tank, water pump, electric control cabinet, pressure controller, safety valve, pressure gauge, check valve, gate valve, and pipeline, forming a complete automatic variable frequency water supply equipment.

　　After the water pump is started, air and water are simultaneously supplied to the tank through the air supply tank and intake valve. As the water level continues to rise, the volume of gas in the tank continues to concentrate; The pressure keeps increasing, and when the pressure reaches the set pressure, the water pump is controlled to shut down through pressure sensing. During the time when the water pump stops running, due to the expansion force of the compressed air, the water in the squeezing tank has a certain pressure and is continuously delivered to the user for use.

　　As water flows out, the volume of water in the tank decreases and the volume of air increases. As a result, the pressure inside the tank gradually decreases. When the pressure inside the tank drops to a predetermined level, the water pump is activated through pressure sensing to continuously stop and start until the ideal water supply effect is achieved in the pipe.

　　Precautions for household variable frequency water supply equipment

　　1. The working environment of the pneumatic water supply equipment should be well ventilated, with a temperature range of 1-50 degrees Celsius.

　　2. The power supply voltage shall not be lower than 350V and not higher than 410V.

　　3. Equipment that has been debugged and qualified shall not be adjusted arbitrarily.

　　4. Under normal operating conditions, the pump should undergo system inspection and maintenance every six months to one year.

　　Selection of household variable frequency water supply equipment

　　1. Choose an automatic systemVariable frequency water supply equipment for daily useThe basic basis is the designed water supply flow rate and water supply pressure (water head), and also needs to consider the type of flow variation for the purpose.

　　Continuous type: There are rarely times in a day when the flow is zero, or when the normal leakage of the pipeline network maintains a certain flow, such as in the pressurization system of large hotels, restaurants, industrial and mining enterprises.

　　Intermittent type: Long periods of low water usage and low or zero flow, for example: small office buildings, office buildings, commercial and residential buildings, various residential buildings, and production water, etc

　　At the same time, various factors such as changes in flow rate during a certain period of water supply, changes in flow rate in different seasons, and differences in water use in different regions should also be considered.

　　5. Fire water supply equipment and sprinkler water supply equipment should generally choose pneumatic water supply equipment, as it is in a long-term system pressure holding state with no flow rate changes. Pneumatic water supply equipment can cope with general pipe leaks and add a small flow auxiliary pump, so there is no need to start the main pump normally, saving energy.

　　Both variable frequency water supply equipment and pneumatic water supply equipment can be selected for domestic water supply, each with its own advantages.

　　Advantages of variable frequency water supply equipment: It can supply water at a constant pressure and the constant pressure value can be adjusted within a certain range. The constant pressure accuracy is generally less than 0.02MPa. Variable frequency speed regulation is an efficient and energy-saving method, with an average energy saving of 20% compared to typical pneumatic water supply equipment. In addition, the impact current of variable frequency starting is small, and the pump's impact is also small, resulting in low noise during low-speed operation. The advantages of pneumatic water supply equipment include relatively low cost, simple control system technology, convenient service, and easy maintenance.
