The two sets of constant pressure water supply equipments which purchased by “The Memorial Hall of Nanjing Massacre” have been installed and debugged successfully.The customer satisfied with the using effect very much.The two sets constant pressure water supply equipments are water softener with atmospheric constant pressure water supply equipment and vacuum deaerator.This type of constant pressure water supply equipment is a new equipment.It adopts expansion tank which can constant pressure.This constant pressure water supply equipment use the principle of vacuum sputtering,to removal free gas in the system,dissolve gas,reduce water resistance,slow down the corrosion of system and equipment,reduce energy consumption,so that the system in a high efficiency,pro-environment and energy-saving state.
Jiangsu and Shanghai are very important market for our company.A lot of customers purchased the UV sterilizers,chemical dosing system,constant pressure water supply equipments which produced by PEIDE.Welcome to our factory to investigate.

The installation precautions of constant pressure water supply equipment as below:
(1)The constant pressure water supply equipment can be placed in the basement heat or basic sandwich.It must avoid open-air setting,because the small-diameter pipe easily damaged by frost.
(2)Safe and reliable power supply requirements, or should take technical measures.
(3)Exhaust pipe and the expansion pipe should be connected to the suction side of the circulation pump return main pipeline.According to the flow direction to connect the exhaust pipe apart two meters,then to connect expansion pipe.Return water flow through the exhaust pipe contacts and then flow through the expansion pipe contacts(constant pressure point).
(4)Water supply pipe connection requires only 0.05MPa pressure,if the water pressure not meet this requirement, it should be supplemented by other technical measures.
(5)In order to avoid a lot of sewage directly into the constant pressure water supply equipment,the connecting pipeline should connect from the top.The details as below:
