Roots vacuum pump is a vacuum pump without internal compression Roots vacuum wholesale telephone, the compression ratio is usually very low, so the high vacuum pump required before the pump. By a pair of leaf cavity pump rotor synchronous, urging action to move the reverse rotation of the vacuum pump exhaust gas is achieved. Roots mechanical vacuum pump means having a pair of soles synchronous high-speed rotation of the rotor, and this alone can not exhaust Roots vacuum pump production and supply, the first stage to be equipped with seals, water ring may be straight rows atmosphere. Roots vacuum pumps are widely used in the metallurgical smelting, degassing, rolling Roots vacuum outlets, as well as chemical, food, pharmaceutical industry, vacuum distillation, vacuum concentration and vacuum drying and so on. Vacuum accessories for use in vacuum noise control, vacuum muffler. Roots vacuum pump periodic inspection: Daily checks: a) the oil level: too much oil, the temperature was increased, the amount of oil is too small, resulting in poor lubrication. b) Temperature check: Check the temperature with a thermometer various parts of the pump. c) motor load tests: the power meter or current, voltage meter to measure the motor load.
