NYP high viscosity pump is a new type of volumetric pump developed according to the requirements of petroleum, chemical, paint, grease, medicine, dye food and other industries. It is suitable for medium temperature within 300 ° C and the viscosity of conveying material can reach 600000 cSt. NYP high-viscosity pump applications are widely used. The main components are pump body, inner and outer rotors, brackets, bearings, etc., which can be carefully selected according to different working conditions. I think the following points can be considered.

 

 1, need to consider the characteristics of the media

(1) Lubricity, cleanliness and corrosiveness of the medium

 If the medium has lubricity and cleanliness is good, then the core part of the pump is better and not easy to wear; the corrosiveness of the medium determines the material of the pump, and whether the pH is acidic or alkaline is important for the choice of the material of the pump; If it is corrosive and toxic, consider whether it is zero leakage (when the viscosity of the medium is allowed, it is generally considered when the viscosity is not very high).

(2) Viscosity and temperature of the medium

 For NYP gear oil pump, the medium viscosity factor is very important. Knowing the viscosity of the medium (and the following outlet pressure) can choose the number of revolutions of the pump and the motor power, shaft power, etc.; Select the overcurrent part material. Also ask the customer carefully, the viscosity of the medium at room temperature and operating temperature, materials that are easy to crystallize at room temperature, you need to consider whether the pump insulation or pipeline heating belt installation is required.

 2, need to consider the pump inlet pressure and outlet pressure

 This is an indispensable factor in the selection process of NYP high viscosity pump. For high viscous medium, if the inlet has positive pressure or normal pressure, it is beneficial to the transportation of medium. When negative pressure is needed, additional consideration is required. The outlet pressure is derived from the resistance of the pipeline, and the high-viscosity medium can provide the height and level setting of the pipeline, whether there are valves or filters, etc., to calculate the pipe resistance and calculate the pump. Design pressure.

 3, the choice of seal

 The choice of NYP high viscosity pump seals depends on the corrosive nature of the media, viscosity and other factors. Generally, the viscosity is large, the packing is sealed, and the low viscosity can be considered mechanical seal.

 4, the pump transmission mode

 NYP high-viscosity pump transmissions are available in bridge and direct connection, depending on the customer's own needs.

 5. Explosion-proof requirements for applicable occasions

 Whether the medium is suitable for explosion-proof occasions. If it is dangerous, it needs to be explosion-proof. Then it is necessary to recommend explosion-proof electrical equipment, and the explosion-proof grade is taken into consideration.
