Triplex single action piston mud pump
Continuous tooth herringbone gear
One-piece alloy steel crank
Renewable crosshead guide
F-2200 mud pump:
1. Power End (frame, pinion shaft, crankshaft, crosshead and extension rod)
Power end features:
Continuous tooth herringbone gear.
One-piece alloy steel crank.
Renewable crosshead guide.
The frame is made of welded steel plate to provide the frame with high strength, good rigidity and lightweight. The extension rod packing is of duplex seal structure to provide the good seal result. The power end uses the combined lubrication system of forced lubrication and splash lubrication.
2.Frame
The frame is made of welded steel plate and by stress relief treatment to obtain good rigidity and high strength. Ribbed plates are used to strengthen the place where the crankshaft bearing is fitted. The frame is furnished with the necessary oil basin and oil way system for cooling and lubricating purpose.
3.Lubrication System
The power end uses the combined lubrication system of forced lubrication and splash lubrication. The pressure oil is conveyed through lubricating pipeline, crosshead, extension rod, crosshead guide and all bearings by a gear oil pump within the oil box to realize the forced lubrication. The working condition of the gear oil pump may be understood from the pressure gauge behind the frame.
