summary
The asphalt heavy oil rotary pump is mainly composed of pump body, pump cover, shaft, gear, rotor, packing, pressure cover and other components. It is an improved high viscosity material delivery pump based on the LC pump. It can be connected to the motor through two forms of belt transmission and gear reducer drive through the base, and can work in any direction. The two ends of the shaft are equipped with skeleton oil resistant seals, and a return oil device is installed in the middle to prevent air intake or oil leakage. An insulation layer is added to the outer surface or end cover of the pump casing, allowing steam or thermal oil to circulate within the insulation layer to achieve insulation for the pump chamber. Therefore, it is more suitable for transporting high viscosity and easily solidified media such as asphalt and crude oil.
principle
In the pump chamber of asphalt heavy oil rotary pump, there are two "8" shaped rotors installed perpendicular to each other on a pair of parallel shafts, and they rotate synchronously in opposite directions by a pair of gear belts with a transmission ratio of 1. Maintaining a certain gap between the rotors and the inner wall of the pump casing can achieve high-speed operation. Due to the fact that Roots pump is a vacuum pump without internal compression, the compression ratio is usually very low, so high and medium vacuum pumps require a front stage pump. The vacuum of a Roots pump depends not only on the structure and manufacturing accuracy of the pump itself, but also on the vacuum of the preceding pump. In order to improve the vacuum degree of the pump, the rotor pump can be used in series.
purpose
Asphalt heavy oil rotary pump has the characteristics of low speed, high efficiency, small volume, large flow rate, low power consumption, strong self suction ability, no need for oil injection, and convenient use. It can be widely used for transporting petroleum and petroleum products (gasoline replaceable copper pump blades) and for transporting various oils and liquids in factories. Such as crude oil, paint, lubricating oil, glass glue, oleic acid, toothpaste, and light alkaline (soap processing) liquids; Food processing can transport various liquids, such as soy sauce, yeast, syrup, etc. And various working conditions such as loading and unloading of oil tankers and oil tankers.
