What is Frequency conversion for water supply machinery?
Frequency conversion water supply equipment’s has become widely used in multi-story residential community living and high-rise building water supply as a result of the development of frequency converter speed control technology and continuous improvement of the quality requirements of drinking water.
The frequency-conversion constant-pressure water supply system includes a control processor PLC, a water storage system, and a water pump set, as well as a frequency converter, with the water storage system and water pump set being connected to the control processor PLC, and the water pump set being further connected to the frequency converter.
Advantages of the Frequency conversion for water supply
1. Low-cost equipment and dependable system operation;
2. Small footprint, which saves energy and water;
3. High degree of automation, ease of use and control;
Pressure tank in frequency conversion water supply machinery
1: By knowing the volume of the pressure tank we can determine the sleep time of the pump.The size of the pressure tank affects the pressure range in which the water supply network operates; in the case of leakage flow (L / s), the size of the pressure tank determines the pump's restart time. The greater the gap time, the larger the volume.As a result, selecting a larger pressure tank can extend the pump's sleep duration.
2: Recognize the volume of the pressure vessel.A pressure tank with a large volume will require more capital investment, inconvenient maintenance, and a long time to inflate.
What is the role of pressure tank in frequency conversion?
How to configure air pressure tanks with very little water for life frequency conversion water supply equipment is an essential component in extending the pump's sleep period, minimizing pump loss, and extending the pump's life.
The pressure of the pipe network itself maintains the system pressure in water supply equipment or systems without air pressure tanks. Because the compression ratio of water is significantly lower than that of gas, it is required to equip the air pressure tank to reduce the start of water pump replacement when the pipe network is as tiny as a power frequency pump to directly provide to the user. The water pump is controlled by frequency conversion to provide according to demand (when the flow rate is zero, the low speed of the frequency conversion control water pump assures the pipe network's "continuous pressure").
The amount of water that can be added to the pipe network within a certain pressure range is determined by the volume of the air pressure tank; when the pipe network has a certain connection flow rate (L/S), the length of the pump restart interval is determined by the volume of the air pressure tank. The higher the volume, the longer the rest period; hence, choosing a larger air pressure tank can extend the pump's sleep time.
