Working Principle and Structure of NYP High Viscosity Internal Gear Pump
NYP high viscosity internal gear pump is a new type of positive displacement pump developed according to the needs of petroleum, chemical and paint industries. Due to the different materials and unique structure, NYP high viscosity internal gear pump is widely applicable to different kinds of viscous Medium temperature: Medium temperature: 10 ℃ ~ 200 ℃ (NYP0.78 and NYP2.3 applicable temperature -10 ℃ ~ 80 ℃) Medium viscosity: 1.0cSt ~ 300000cSt (NYP0.78 and NYP2.3 suitable medium viscosity 1.0cSt ~ 10000cSt) 1, Working principle: The drive gear (outer rotor) with internal teeth drives the inner rotor to rotate in the same direction in the fully enclosed pump body. The crescent plate of the pump body and the front cover separate the suction inlet and the discharge outlet . Rotation, the negative pressure in the suction inlet, the liquid is sucked in, the rotor will bring the liquid to the discharge port, the pressure discharged from the pump body to complete the liquid transport. 2. Structure: The pump is mainly internal and external rotor, shaft, Front cover, bracket, seal, bearing, etc. There are two forms of seal, mechanical seal and packing seal, which are sealed with packing for high temperature, high viscous density and strong corrosive medium. Cover and pump body can be designed with a thermal jacket J J steam valve can be equipped with safety valve J When the pump or pipe system overpressure J safety valve open J form an internal reflow J to ensure system safety Pump device by the pump motor and base composition of the transmission bridge And direct two. From the spindle extension to the pump, clockwise rotation. NYP high viscosity internal tooth pump advantages: 1, the delivery of liquid smooth, no pulsation, vibration, low noise. 2, there is a strong Of the self-priming performance 3, the correct selection of parts materials, can transport a variety of corrosive media, the use of temperature up to 200 ° C 4, the same internal and external rotor rotation, wear small, long life 5, the pump speed and flow was Linear function, can change the speed to change the pump flow 6, Especially suitable for high viscosity medium transport.
