The role of water replenishing pump in circulating system
There are three ways of constant pressure in water system. 1, the expansion tank constant pressure, this method applies to small and medium water systems, low cost. 2 water pump constant pressure, the role is when the system because the water shortage during the operation, resulting in insufficient pressure, the water supply system can play the role of water pressure. 3 pressure tank fixed pressure, pressure tank fixed pressure at the same time, also need replenishment pump water, the individual feel that the first two kinds of economic reality

The water loss, if the level is too much loss, circulation system will not have a negative effect, the other, needs to pay for water pump system, are generally set up a level, when the automatic water level below this post.
In the circulatory system, the replenishment pump acts as a means of circulating water to the heating system and to supplement the water lost by the circulatory system. Most heating systems use a constant pressure pump to ensure that users of any degree of the system can normally cycle hot water.The fire unit is normally there are many, including the general use of the unit: water supply pump, fire pump, filling, pressure relief valve, pressure sensor, one-way valve, fire tank must maintain the required pressure, when the pressure drop or leak, the pressure sensor will fire a signal to the irrigation control cabinet, and control the cabinet module will give a water pump signal, such as a water pump after receiving the signal will immediately start running, to the fire in the irrigation water, irrigation water until the fire to the set pressure, the fire control cabinet will give irrigation pressure sensor signal, let the water pump will automatically stop running. Water pump and pressure regulating pump the same principle, are used for replenishment pressure.
