SN series screw spindle pump can handle sending lubricating oil, low lubricity liquid, non-corrosive mineral oil, viscous liquid and other lubricating liquid media, including lubricating oil, fuel oil, heavy diesel oil and various synthetic rubber liquids. The equipment has a small size, light weight, low vibration, low noise, self-priming ability, stable output, compact structure and other characteristics, so it is used as an ideal choice for transporting lubricating oil, fuel oil, heavy diesel oil and a variety of synthetic rubber liquids and other media.
Product Details:
SN series three screw pump is mainly composed of pump body, three screws, shaft seal, safety valve and other components. The three screws mesh with each other and are installed in the pump cylinder to form several levels of dynamic sealing chamber. When the motor or motor drives the active screw to rotate, the active screw engages with the driven screws on both sides, forming continuous and mutually isolated airtight chambers in the pump body. With the rotation of the screw, these sealed chambers gradually form a vacuum, and the liquid is sucked in by the suction port under atmospheric pressure. The absorbed liquid is enclosed in the sealed chamber, and with the rotation of the screw along the axial continuous, pulsation-free transportation to the discharge port.
Advantage:
1. Petrochemical industry: It is utilized for conveying all kinds of lubricating oils, hydraulic oils, fuel oils, etc. It plays an important role in the process of petroleum refining, chemical production, and so on.
2. Mechanical manufacturing: as the power source of hydraulic system, it provides stable hydraulic power for various mechanical devices, and it can also be used for conveying lubricating oil and cooling oil.
3. Food and Pharmaceutical: It can be used to convey food, medicine and other fluids with certain viscosity to meet the health and safety requirements of the food and pharmaceutical industries.
4. Electric power industry: It is widely used for conveying lubricating oil, insulating oil, etc. in the fields of thermal power generation and hydroelectric power generation.
5. Shipbuilding industry: It is used as fuel delivery pump and lubricating oil pump for ships, providing guarantee for the normal operation of ships.
Feature:
1. The rotor of this series of pumps adopts hydraulic balancing design, with low vibration, low noise, stable and pulsation-free output, and can be operated stably for a long time at higher speeds.
2. With strong self-priming ability, the pump can quickly self-priming and transport fluid without external auxiliary devices, applicable to a variety of complex working conditions.
3. SN series screw pumps have high volumetric and mechanical efficiencies, which can realize efficient fluid transfer with low energy consumption.
4. The compact structure of the pump body, small volume, light weight, easy to install and maintain, can effectively save space.
Precautionary:
1. During installation and commissioning, the pump should be operated in strict accordance with the installation instructions provided by the manufacturer to ensure that the pump is installed in the correct position, the inlet and outlet are firmly connected, and the seal is good.
2. SN series screw pumps are suitable for conveying non-abrasive oil-based fluids with a certain degree of lubricity. For media containing solid particles or highly corrosive, special configuration or selection may be required.
3. Regular maintenance of the pump, including replacement of lubricating oil, inspection of seals, cleaning of filters, etc., in order to ensure the normal operation and prolong the service life of the pump.
