LCW high viscosity Roots pump is based on the LC pump, in order to solve the delivery of asphalt and condensate made of modified, in the pump shell or cover the end of the insulation layer, the use of steam or heat transfer oil circulating pump chamber Insulation, which pump the continuous work and intermittent work, to provide convenient and good conditions. LC Roots pump works: In the pump chamber, there are two "8" -shaped rotor perpendicular to each other mounted on a pair of parallel shaft, the gear ratio of 1 pairs of gear with a reverse rotation of the synchronous rotation of each other movement. Between the rotors, between the rotor and the pump housing to maintain a certain gap, you can achieve high-speed operation. As Roots pump is a type of vacuum pump without internal compression, the compression ratio is usually low, so the high and medium vacuum pumps require a foreline pump. Roots pump ultimate vacuum in addition to depend on the pump structure and manufacturing accuracy, but also depends on the foreline pump ultimate vacuum. In order to increase the pump ultimate vacuum, Roots pumps can be used in series. The Roots pump works like a Roots blower. Due to the constant rotation of the rotor, the drawn gas is sucked into the space v0 between the rotor and the pump housing through the air inlet and then discharged through the air outlet. Since inhaled v0 space is completely closed state, so the gas in the pump chamber is not compressed and expanded. However, when the top of the rotor turns over the edge of the exhaust port, when the v0 space communicates with the exhaust side, since the pressure of the exhaust side gas is higher, a part of the gas bounces back into the space v0 to make the gas pressure suddenly increase. When the rotor continues to rotate, the gas is discharged outside the pump. LC Roots oil pump for conveying temperature not higher than 140 ℃ of crude oil, sugar, starch, yeast light alkaline liquid. Uses: petroleum, food and other industries. Structural features: LC Roots oil pump consists of pump body, pump cover, shaft, gear, rotor, packing, gland and other components, the pump with belt drive and gear reducer drive two forms, can reverse the role of the shaft two Oil-resistant seal with a skeleton at the end, equipped with a return device in the middle to prevent gas or oil spills.
