NYP SERIES INTERNAL GEAR PUMP

¡ñ BRIEF INTRODUCTION
¡¡¡¡NYP series internal gear pump is a kind of new positive displacement pump, and is designed according to the different fields' requirements of petroleum ,chemical industry ,paint ,medicine ,foodstuff and so on. It widely applies to a variety of mediums with different property and viscosity because of special structure and selected different pump's matenrials.
¡¡Proper medium temperature:-10¡æ¡«200¡æ(about NYP0.78& NYP2.3:-10¡æ¡«80¡æ)
¡¡Proper medium viscosity:1.0cSt¡«300,000cSt(about NYP0.78 & NYP2.3,1.0cSt¡«10000cSt)¡£

¡ñ Type of structure(As gigure)
¡¡¡¡£¨1£©Work principle
¡¡driving gear £¨outside rotor£©with internal tooth drives the internal rotor and turns in same direction in the full closed pump body. The inlet from the outlet. When it turns, negative pressure formed at the suction port, the liquid inhaled and being take to the outlet by rotor, then the liquid is expelled from the discharge port as the gears mesh. The transpor-tation of liquid finished.
¡¡£¨2£©Structure Feature
¡¡As figure I The pumps are mainly composed of internal rotor, outside rotor, shaft, pump casing, front cover, seal, bearing etc.
¡¡The pump 'seal adopts packing seal or mechanical seal. When the delivered medium is high temperatur ,high visc or strong corrosion, packing seal should be adopted.
¡¡When the delivered medium is easy crystallinic ,we can design the heat preservation jacket in pump casing and front cover in order to melt the medium with steam when working. The pump can be also fitted with the safety valve.
¡¡The pump set is composed of the pump, motor and baseplate.
¡¡The driving way is belt wheel driving or coupling driving.
ADVANTAGES
¡¡1)Steady delivery without pulsation ,little vibration and noise.
¡¡2)Outstanding self-priming abitity.
¡¡3)The pump can deliver the varied corrosion mediums if the proper material of parts selected. In addition ,the working temperature can reach 200¡æ.
¡¡4)The same rotary direction of internal rotor and outside rotor results in little wear and long operation life .
¡¡5)The pump's flow capacity can be changed through adjusting the speed.
¡¡6)It's specilly suited to deliver high visc medium.
