ปั๊มโคลน Emsco F Series (HBMP)

Triplex Single Acting Mud pump
The Triplex Single Acting Mud pump is machined with all fluid end parts interchangeable to that being machined by OEM plants.
HBF-500, HBF-800 and HBF-1000/1300/1600 Mud Pumps

I. Power End (frame, pinion shaft, crankshaft, crosshead and extension rod)
1. 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 light weight. The extension rod packing is duplex seal structure to provide the good seal result. The power end uses the combined lubricating system of forced lubrication and splash lubrication.

2. The frame:
The frame is made of welded steel plate and stress relief treated to obtain the good rigidity and high strength. The place where the crankshaft bearing is fitted is strengthened by using ribbed plates. The frame is furnished with the necessary oil basin and oil way system for cooling and lubricating purpose.

3. Crankshaft
The crankshaft is made of cast alloy steel and furnished with herringbone gear, connecting rod and bearing. The tooth form of the big geared ring is herringbone gear. The gear bore and the crankshaft surface are interference fitted and they are both fastened with bolts and lock nuts. The big end of the connecting rod is mounted on three eccentric straps of the crankshaft through single row short cylindrical roller bearings and the small end on the crosshead pin through double row long cylindrical roller bearing. Double row radial spherical roller bearings are mounted at both ends of the crankshaft.

4. Pinion shaft

II. Fluid End (module, valve assembly, liners and pistons)

1. Module
Module is made of forged alloy steel and three modules of each pump are interchangeable. Valve-over-valve (through type cylinder) design reduces the cylinder volume and promote the volumetric efficiency. At customers' request, the cylinder surface may be nickel plated to improve the abrasion resistance.
Discharge pulsation dampener, shear relief valve and discharge strainer are furnished at the outlet. HBF-500 pump suction inlet is fitted with 8"flange, HBF-500 pump suction inlet with 10"flange and HBF-1000 pump suction inlet with 12"flange.

2. Valve Assembly
The suction valve and the discharge valve for above three mud pumps are interchangeable. HBF-500 mud pump uses API#5 valve pot, HBF-800 and HBF-1000 mud pumps use API#6 valve pots.

3. Liners
Bi-metal liners are used. The sleeve is made of wear-resistant cast iron and the surface hardness is HRC60-65. Therefore, liners feature wear resistance, corrosion resistance and high surface finish. Liners are put in from the cylinder cover bore in the front of the Module and fixed with liner cage, cylinder cover plug and cylinder cover when installing.

4. Pistons and Piston Rods
They are slide fitted, sealed with rubber seal ring and finally fastened with lock nuts to prevent the piston from looseness and to play a role in sealing.
Modules, liners, pistons, valves, valve seats, valve springs, seal rings, valve covers and cylinder covers at the fluid end of HBF-800 and HBF-1000 mud pumps are all interchangeable.
