Shandong Qingneng power Co.,Ltd. Produces mud pumps and its main spare parts conform to API standard. Power End Features: One-piece alloy steel crankshaft.Renewable crosshead guide. The frame is made of welded steel plate to providethe frame with high strength, good rigidity and lightweight. The extension rodpacking is of duplex seal structure to provide the good seal result. Double rowradial spherical roller bearings are mounted at both ends of the crankshaft.The Cylinder is made of molten alloy steel. Valve-over-valve (through typecylinder) design reduces the cylinder volume and promotes the volumetricefficiency. We have got two patents in petroleum machinery. The patents No. areZL200720027843.6 and ZL200720027939.2.
Features
1)Power end features
Continuous tooth herringbone gear. One-piece alloy steelcrank. Renewable crosshead guide. The frame is made of welded steel plate toprovide the frame with high strength, good rigidity and lightweight. Theextension rod packing is of duplex seal structure to provide the good seal result.The power end uses the combined lubrication system of forced lubrication andsplash lubrication.
2)Crankshaft
The crankshaft is made of cast alloy steel and is furnishedwith big geared ring, connecting rod and bearing. The tooth form of the big-gearedring is herringbone gear. The gear bore and the crankshaft surface isinterference fitted and they are both fastened with bolts and lock nuts. Thebig end of the connecting rod is mounted on three eccentric straps of thecrankshaft through single row short cylindrical roller bearings and the smallend on the crosshead pin through double row long cylindrical roller bearing.Double row radial spherical roller bearings are mounted at both ends of thecrankshaft.
3)Cylinders
Cylinders are made of forged alloy steel. Three cylinders ofeach pump are interchangeable. Valve-over-valve (through type cylinder) designreduces the cylinder volume and promotes the volumetric efficiency. Atcustomers request, the cylinder surface may be nickel plated to improve theabrasion resistance.
