The main business agent sells the whole machine parts, engines and
chassis parts of large-scale famous construction machinery at home
and abroad. Komatsu, Japan, Caterpillar, USA; Domestic products: bulldozer and excavator series products such as
Shantui, Yellow River, Shanghai Peng Pu, etc., which are used in 25
provinces (cities) and autonomous regions in China. Among them, some bulldozer oil pump products are matched with
domestic bulldozer factories and exported with the whole vehicle. Products are exported to Middle East, Far East, Southeast Asia,
Africa, Europe, America and other countries and regions.
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 thr outlet by
rotor,then the liquid is wxpelled from th discharge port sa 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 designthe
heat preservation jacket in pump casing and front cover in order to
melt the medium with steam wen working.The pump can be also fitted
with the safty valve. The pump set is composed of the pump,motor
and baseplate.
The driving way is belt wheel driving or coupling driwing.
3. ADVANTAGES:
1) Steady edlivery without pulsation ,little vibration and noise.
2) Outstanding self-priming abitity.
3) The same rotary direction of internal rotor and outside rotor
results in little wear and long loperation life .
4) The pump's flow capacity can be changed through adjusting the
speed.
5) It's specilly suited to deliver high viscosity medium.
