ZJQ series of air-cooled Roots vacuum pumps, vacuum pump is the basis of ZJ series Roots adds bypass gas cooling system derived from the new products. Due to its special design, it can be the difference between the high pressure and high compression ratio of long-term reliable operation. Cooling gas enters from the suction side of the pump within the pump chamber, the pump and the compressed gas will not be overheated, but has no effect on the pumping performance of the pump. Each pump motor is cooler and the necessary accessories, coolers and motor specifications are based on different operating conditions may be. Roots vacuum pump can be used alone production and supply, or with liquid ring vacuum pumps and vacuum pumps Roots series into common units, to achieve a higher degree of vacuum to meet various process requirements. BZJ series two-stage Roots pump main structure and principles: 1, the rotor: Roots vacuum pump rotor is the core component of the design process requires high Roots vacuum pumps, made by precision CNC machining, each a total of four, mounted on a pair of parallel shafts, each shaft assembly of different sizes, two rotors; 2, case: according to a certain proportion of Roots vacuum pumping speed of price, housing the Central sizes of two chambers, namely the level of vacuum cavity; 3, synchronous gear: Gear is one of the core components of Roots vacuum pump, which is used to ensure synchronous rotation of the two rotors and keep the gap between the rotor Roots vacuum pump uses a gear surface by high-frequency quenching, and then by a special high-precision grinding together; 4, has been pumping gas from the suction port to enter the high-vacuum chamber, and then pass into the low wall of the vacuum chamber through the air, and finally through the discharge port to the next pump. Roots vacuum use, Zhucheng East Han Machinery Co., Roots vacuum provided by Zhucheng East Han Machinery Co. Zhucheng East Han Machinery Co., Ltd.
