Overview:

SNH three screw pump is designed and manufactured according to the national standard GB10887-89. Three screw pump is a rotor type positive displacement pump, it is the use of screw meshing principle, relying on the rotating screw in the pump sleeve to engage each other, the conveyed medium is closed in the meshing cavity, along the screw axis to continuously push to the discharge outlet at a constant speed, to provide stable pressure for the system. The three screw pump is suitable for conveying all kinds of non-corrosive oils and similar oils and lubricating liquids. The viscosity range of the transported liquid is generally 3.0 ~ 760mm2/S(1.2 ~ 100°E), and the high-viscosity medium can be transported by heating and reducing the viscosity. Its temperature generally does not exceed 350 ° C.

Insulated screw pump (insulated drain pump) is mainly used to transport high viscosity and high temperature lubricating liquid. Often used in asphalt, heavy fuel, heavy gear oil and other media transport. The hot carrier can be steam, hot oil and hot water, and the cold carrier can be a gas or liquid. This product is widely used in petroleum, chemical industry, metallurgy, machinery, electrical, chemical fiber, glass, highway and other industries.

Advantages:

(1) Wide range of pressure and flow, flow range 0.2 ~ 600m3/h maximum working pressure up to 6.3MPa;

(2) A wide range of types and viscosity of liquids transported;

(3) Because the inertia force of the rotating parts in the pump is low, a high speed can be used;

(4) Good aspiration, with self-imbibition ability;

(5) Uniform and continuous flow, small vibration, low noise;

(6) Compared with other rotary pumps, it is less sensitive to incoming gas and dirt;

(7) Solid structure, easy installation and maintenance;

(8) SN three screw pump, self-priming;

(9) Due to the general combination of parts series have a variety of structures, can be used for horizontal, flanged and vertical installation;

(10) Heating or cooling structures can also be provided according to the needs of the conveying medium;

Usage and Scope of use:

It is used on ships as transport, pressurization, fuel injection and lubrication pump and Marine hydraulic device pump.

Used in heating equipment as fuel injection, fuel supply and delivery pump.

Used in the mechanical industry as hydraulic, lubricating and remote control motor pumps.

It is used as a loading, conveying and liquid supply pump in the chemical, petrochemical and food industries.

Three screw pump is widely used in petroleum, chemical fiber, metallurgy, machinery, electric power, machine tools, ships, glass, highway and other industries.

Three screw pump is suitable for conveying fuel oil, lubricating oil, hydraulic oil, crude oil, asphalt and other lubricating liquids similar to oil.

The three-screw pump is used as a lubrication pump in the industrial field, a hydraulic pump in the hydraulic system, and a conveying and booster pump in the fuel system. It is used as conveying and filling pump in oil transmission system.
