The spiral slice single stage oil circulation vacuum pump and the spiral slice double stage oil circulation vacuum pump are the necessary equipment for extracting gas from the closed container to obtain vacuum. spiral slice double-stage vacuum pumps are vacuum pumped and regenerated on the basis of single-stage pumps. It can make the system reach the highest point of vacuum.
(1) Design to prevent oil return
The intake passage is specially designed to prevent pumping oil from returning to the pumped containers and pipes after the pump stops running.
(2) Environmental protection design
The design of the built-in defogging device and the installation of an oil-gas separator at the exhaust port can effectively deal with the oil pollution in the process of oil discharge.
(3) Aluminum alloy shell of motor
The motor adopts aluminium alloy shell, which has high heat dissipation efficiency, ensures long-term normal operation and better appearance quality.
(4) Integrated Design
The integrated design of motor and pump makes the product more rigorous and reasonable.
(5) Big Start Time
Our products are specially designed for low temperature and voltage environments. Ensure that the machine starts normally when the ambient temperature is lower (> - 5 C) and the voltage is lower (> 180V) in winter.
