No negative pressure frequency conversion pump is a new type of water supply equipment, the pump unit, control equipment, booster regulator three major components, water supply capacity by the pump unit decision. Now to say no negative pressure pump the main function and application range. Negative pressure variable frequency pump First, the main function of vacuum pump without negative pressure 1, automatic completion of multiple pump units soft start, frequency to power frequency operation and stop all the operation. 2, according to changes in water consumption, into more than one pump group start and stop. 3, pressure setting and the actual pressure value of the LED display. 4, LED frequency indication, frequency error indication, motor fault condition display. 5, protection: with undervoltage protection, overvoltage protection, overload protection, short circuit protection, stall prevention, burn prevention and other functions. Second, no negative pressure pump applications 1, no negative pressure pump is widely used in high-rise buildings, residential areas, villas and other residents living water. 2, no negative pressure pump is widely used in enterprises, public institutions, hotels, office buildings, department stores, large saunas, hospitals, schools, stadiums, golf courses, airports and other places of daily water. 3, no negative pressure pump is widely used in manufacturing, washing equipment, food industry, factories, industrial and mining production water. 4, Other: no negative pressure pump is widely used in the transformation of the old pool water and other forms of water Further Reading: pump valve pipe fittings Exhibition 2016 Exhibition of Information Industry, Internet (Xiamen) Technology Co., Ltd.
