Roots vacuum pump (Roots pump) is a rotary varactor vacuum pump. Roots vacuum pump according to the different scope of work, is divided into straight row of atmospheric vacuum Roots pump, vacuum Roots pump (also known as mechanical booster pump) and high vacuum multistage Roots pump. Now to talk about the Roots pump features and uses.

First, the Roots pump features

In the wider pressure range has a larger pumping speed;

Insensitive to the dust and water vapor contained in the evacuated gas;

Rotor does not have to be lubricated, no oil in the pump chamber;

Small vibration, rotor balancing conditions are good, there is no exhaust valve;

Low speed, high efficiency, small size, large flow, low power consumption, self-absorption ability, no oil, easy to use and so on.

Second, Roots pump use

Can be widely used in transportation of petroleum and petroleum products (gasoline pump for copper leaf) and the factory to convey a variety of oils and liquids. Such as crude oil, paint, lubricants, glass plastic, oleic acid, toothpaste and light alkaline (soap processing) liquid; food processing can transport a variety of liquids such as bean paste, soy milk, syrup and so on. Loading and unloading all kinds of tankers and tanker speed, high efficiency, easy to use, can be positive and negative work.

Prepainted Steel Coil

Color coated Steel Coil is mainly divided into three parts: construction, household appliances and transportation. Building is generally used to build the roof, wall and door of industrial and commercial buildings such as steel structure workshop, airport,warehouse and freezer. Household appliances are used in the production of refrigerators and large air conditioning systems, freezers, toasters, furniture, etc. Transportation industry is mainly used for oil pan, automobile interior parts, etc.

PPGI is a product made of cold-rolled steel coil and (aluminum) Galvanized Steel Coil after surface chemical treatment, coating (roll coating) or composite organic film (PVC film, etc.), and then baking and curing. This product is produced by the manufacturer in coils on the continuous production line, so it is also called prepainted steel coil. It not only has the properties of high mechanical strength and easy forming of steel materials, but also has good decoration and corrosion resistance of coating materials.
