One, JZJP Roots water spray application and characteristics of vacuum unit: JZJP Roots water jet vacuum unit is also called LSJ Roots-type water jet pump unit with pumping capacity, high vacuum characteristics, can be separately, the rough vacuum when water injection pumps, high vacuum, the longer the series on the Roots pump, ultimate vacuum up to 150Pa, water jet pump vacuum degree limit temperature limit by only up to a certain limit vacuum series on Roots vacuum pump can achieve a higher after vacuum, and mechanical ventilation than normal jet vacuum pump or a series of soft drinks should be large, suitable for light industry, food, pharmaceutical, oil, pesticides and other industries. Two, JZJP Roots water jet vacuum unit works: JZJP Roots water jet vacuum unit works is the use of two energy transfer fluid to create a vacuum, Roots pump works by using a constant rotation of the rotor generating compressing a vacuum. According to the actual needs of customers can design more complete unit level in order to improve the capacity and vacuum pumping unit. See: 2LSJ Roots-type two water jet vacuum unit, F3LSJ Roots water jet vacuum unit.
