NYP high viscosity rotary pump

NYP high viscosity rotary pump

The NYP high viscosity rotary pump belongs to the internal meshing rotary pump. The working principle of the NYP internal meshing rotary pump is that the driving gear (outer rotor) with internal teeth drives the inner rotor to rotate in the same direction inside the fully enclosed pump body. The crescent plate on the front cover of the pump body separates the suction and discharge ports. When the rotor rotates, negative pressure is formed at the suction port, and the liquid is sucked in. The inner and outer rotors carry the liquid to the discharge port, and the liquid is discharged from the pump body under pressure, completing the transportation of the liquid. The high viscosity rotary pump is a new type of positive displacement pump developed by Botou Gear Pump Factory based on the needs of industries such as petroleum, chemical, coatings, oils, pharmaceuticals, dyes, and food. As the NYP high viscosity rotary pump belongs to the internal meshing rotary pump, it works on the same principle as the gear pump and can be made of different materials and has a unique structure. Therefore, it is widely used for conveying media with different properties and viscosities.
● Scope of application
NYP internal meshing rotor pump is suitable for transporting pure and viscous fluids, and can be used for transporting oil products such as lubricating oil, crude oil, etc; It can also be used to transport high viscosity materials such as rubber, asphalt, paint, adhesives, dyes, coatings, lubricants, polyols, food, pharmaceuticals, etc. that do not contain particulate impurities; It can also be used to transport high-temperature, high viscosity polymer melt materials, and even semi-solid liquids. Widely used in industries such as petroleum, chemical, oil and fat, pharmaceuticals, dyes, coatings, etc.
The applicable medium temperature for NYP high viscosity rotary pump is -10 ℃ -200 ℃ (the applicable temperature for NYPO.78 and NYP2.3 is -10 ℃ -80 ℃).
The NYP high viscosity pump is suitable for medium viscosity ranging from 1.0cSt to 300000cSt (NYPO.78 and NYP2.3 are suitable for viscosity ranging from 1.0cSt to 10000cSt).
● Structural characteristics
NYP internal meshing rotor pump is a type of positive displacement internal rotor pump. The rotor structure is a low tooth difference cycloid rotor structure, and the rotor tooth shape is a short amplitude epitrochoid, which is less prone to biting compared to the traditional one tooth difference cycloid rotor structure. The advantages of this structure are small tooth slip, balanced force distribution, and smooth operation. The NYP internal meshing rotor pump is mainly composed of inner and outer rotors, shafts, pump bodies, front covers, seals, bearings, etc. The seals have two forms: mechanical seals and packing seals. When conveying materials that are prone to crystallization, insulation sleeves can be designed on the front cover and pump body for insulation during operation. The pump head, pump housing, and sealing chamber can all be equipped with insulation jackets. Choose the location that requires insulation according to actual needs. The pump can be equipped with a safety valve, which ensures system safety when the pipeline system is overpressure. The pump device consists of a pump, a motor, and a base.
Advantages of NYP rotary pump:
(1) Smooth liquid transportation, no pulsation, low vibration, and low noise.
(2) Has strong self-priming performance.
(3) Proper selection of component materials can transport various corrosive media and can be used at temperatures up to 200 ℃.
(4) The inner and outer rotors have the same direction of rotation, with minimal wear and a long service life.
(5) The speed of the pump is linearly related to the flow rate, and the pump flow rate can be adjusted by changing the speed appropriately.
(6) NYP high viscosity pump can meet the process requirements of the pump at different viscosities by adjusting the gear clearance according to the viscosity needs.
