WZG non-negative pressure frequency conversion water supply equipment

WZG non-negative pressure frequency conversion water supply equipment

Features and Benefits
The frequency conversion start is used to avoid pressure fluctuations caused by the power frequency start to the pipe network, and each pump is started with a reduced pressure or a soft start, which eliminates the inrush current at the start and prolongs the service life of the equipment. The pumps are started cyclically, so that the pumps will not rust due to long-term use or wear out due to frequent use.
Four features：
1.No need to set up reservoirs and high-level water tanks.
The non-negative pressure water supply equipment is directly connected to the municipal pipe network, and there is no need to build reservoirs and high-level water tanks, which saves engineering investment and reduces the occupation of construction area. When the water supply of the municipal pipe network is sufficient, the volume of the non-negative pressure steady flow tank is small, and the entire equipment occupies a small area. The equipment installation only needs to be connected to the water inlet and outlet pipes, which is extremely convenient.

2.No secondary pollution of water sources
The non-negative pressure steady flow tank and the entire set of equipment pipelines are all closed, from the municipal pipe network to the user tap, there is no secondary pollution by the sundries and dirt in the air, and there is no negative pressure steady flow source flowing through the tank. The flow part adopts the anticorrosive treatment of the inner wall paint of the food container, and the paint and the whole machine of the non-negative pressure water supply equipment meet the relevant food hygiene standards.

3.Significant energy savings
The traditional secondary pressurized water supply method uses reservoirs and high-level water tanks. When the municipal pipe network water supply pressure is put into the reservoir, energy loss is exhausted, and energy waste is serious.
After adopting the non-negative pressure steady flow tank, the municipal pipe network water supply pressure is directly superimposed on the feed water pump inlet, and the pump only needs to supplement the insufficient pressure of the municipal pipe network, and the energy saving effect of the whole machine is significant.

4.No need to set up a stabilized pump and a large-volume pneumatic pump
Generally, the water supply equipment is equipped with a pressure-stabilizing pump with a small flow rate and a large-volume WXQ diaphragm pressure tank in order to ensure that the user avoids frequent start-up of the water supply pump at night when the user uses a small flow of water or when the flow enters the pipe network. A one-time investment has also increased the operating costs of the equipment (the operating power consumption of the stabilized pump at night).
