Roots oil pump mainly has two rotors with opposite rotation directions located in the pump body and driven by a pair of synchronous gears. The rotor, like the cam pump, is available in double-leaf, three-leaf and multi-leaf types. There are many types of shapes. The working principle of Roots oil pump I know that in the pump chamber, there are two glyph-shaped rotors installed vertically on a pair of parallel axles, driven by a pair of gears with a transmission ratio of 3, to drive synchronous rotation in opposite directions to each other. There is a certain gap between the rotors and the inner wall of the pump casing, which allows high-speed operation. Since the insulated Roots oil pump is a vacuum pump without internal compression and usually has a very low compression ratio, high and medium vacuum pumps require a backing pump. The ultimate vacuum of the insulated Roots oil pump not only depends on the structure and manufacturing accuracy of the pump itself, but also depends on the ultimate vacuum of the backing pump. In order to improve the ultimate vacuum degree of the pump, insulated Roots oil pumps can be used in series.
Thermal insulation Roots oil pump has the following characteristics
Large pumping speed within a wide pressure range
Quick start and can work immediately
Tolerance to dust contained in the pumped gas Insensitive to water vapor
The rotor does not need to be lubricated, there is no oil in the pump chamber
The vibration is small, the rotor dynamic balance condition is good, there is no exhaust valve
The driving power is small, and the mechanical friction loss is small
/> Compact structure, small footprint
Low operation and maintenance costs.
Therefore, insulated Roots oil pumps are widely used in metallurgy, petrochemical, papermaking, food, and electronics industry sectors. Roots oil pump consists of pump body, pump cover, shaft, gear, rotor, packing, gland and other components. The pump has two forms of belt drive and gear reducer drive, and can be reversed. Skeletons are installed at both ends of the shaft. Oil-resistant seal, with an oil return device installed in the middle to prevent air intake or oil leakage.
The high viscosity insulated Roots oil pump produced by our company is divided into two forms: belt drive and gear reducer drive. This pump has low rotation speed, high efficiency, small volume, large flow, low power consumption and strong self-priming ability. , no need to draw oil, easy to use and other features. It can be widely used to transport petroleum and petroleum products (copper pump blades can be replaced for gasoline) and to transport various oils and liquids in factories. The high viscosity insulated Roots oil pump is based on the original pump and is modified to transport asphalt and condensate oil. An insulation layer is added to the surface or end cover of the pump casing, and the working chamber of the pump is insulated by steam or thermal oil circulation. , thus providing convenient and good conditions for the continuous and intermittent operation of the pump.
