Product name : CHINA FACTORY SNH TRIPLE THREE SCREW PUMP FOR HEAVY OIL,IT IS USED AS FUEL INJECTION PUMPS, FUEL SUPPLY AND TRANSPORTATION, HYDRAULIC, LUBRICATING AND REMOTE CONTROLLED MOTOR PUMPS, PUMPS FOR LIQUID DELIVERY
Product No. : 202212210405
Details:
●Overview:
The SNH type three-screw pump produced by our company is designed, manufactured and produced according to the standard GB10887-89. The three-screw pump is a rotor-type positive displacement pump. It uses the principle of screw meshing and relies on rotating screws to mesh with each other in the pump sleeve to enclose the transported medium in the meshing chamber and push it continuously and evenly along the axial direction of the screw to the discharge port to provide stable pressure for the system. The three-screw pump is suitable for conveying various non-corrosive oils and similar oils and lubricating liquids. The viscosity range of the conveying liquid is generally 3.0~760mm2/S (1.2~100°E), and the high-viscosity medium can be transported after heating and viscosity reduction. Its temperature generally does not exceed 350℃.
●Advantages:
(1) Wide pressure and flow range, flow range 0.2~600m3/h, high working pressure up to 6.3MPa;
(2) Wide range of types and viscosities of liquids to be transported;
(3) Because the inertial force of the rotating parts in the pump is low, a high speed can be used.;
(4) Good suction performance and self-priming ability;
(5) Uniform and continuous flow, low vibration and 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) Three-screw pump, self-priming;
(9) Due to the universal combination of components, there are a variety of structures in the serialization, which can be used for horizontal, flange and vertical installation.;
(10) Heating or cooling structure can also be provided according to the needs of the conveying medium;
●Purpose and scope of use:
It is used as fuel injection, fuel supply and delivery pump in heating equipment.
It is used as hydraulic, lubricating and remote control motor pumps in the machinery industry.
It is used as a loading, conveying and liquid supply pump in the chemical, petrochemical and food industries.
It is used on ships as conveying, pressurizing, fuel injection and lubricating oil pumps, as well as marine hydraulic device pumps.
Three-screw pumps are widely used in petroleum, chemical fiber, metallurgy, machinery, electric power, machine tools, ships, glass, roads and other industries.
The three-screw pump is suitable for conveying fuel oil, lubricating oil, hydraulic oil, crude oil, asphalt and other lubricating liquids similar to oils.
The three-screw pump is used as a lubrication pump in industry, a hydraulic pump in a hydraulic system, a conveying and booster pump in a fuel system, and a conveying and refueling pump in an oil delivery system.
