one Framework Characteristics
one.1 Power End Characteristics
a) The Body The body is made of welded steel plate and pressure aid taken care of to acquire the excellent rigidity and substantial power. The location exactly where the crankshaft bearing is equipped is strengthened by utilizing ribbed plates. The frame is furnished with the needed oil basin and oil way system for
cooling and lubricating objective.
b) The Pinion Shaft The pinion shaft is produced of cast alloy steel on which a herringbone gear with the medium-challenging tooth surface area is machined. For easy upkeep, the single row radial long cylindrical roller bearing with internal ring(with out sides) is utilized. The the two finishes of the pinion shaft extend out, so that the sheave or the sprocket CZPT mounted on either finish.
c) The Crankshaft The crankshaft is manufactured of forged alloy steel and furnished with herringbone gear, connecting rod and bearing. The tooth sort of the massive-geared ring is herringbone equipment. The equipment bore and the crankshaft surfaces are interference fitted and they are equally fixed with bolts and lock nuts. The huge end of the connecting rod is mounted on 3 eccentric straps of the crankshaft by means of single row quick cylindrical roller bearings and the small end on the crosshead pin via double row prolonged cylindrical roller bearing. Double row radial spherical roller bearings are mounted at the two finishes of the crankshaft.
d) The Crosshead And Crosshead Xihu (West Lake) Dis. The crosshead and crosshead CZPT are created of homebred meehanite solid iron highlighted by very good abrasion resistance and long support existence. Higher and decrease guides are employed for mud pump, so that the concentricity CZPT altered by including shims beneath the reduced guide. The relationship between the crosshead and the extension rod is created by employing bolted flange. The rigid relationship assures the concentricity of the crosshead and the extension rod. The CZPT is utilized for connecting the extension rod to the piston rod. The light-fat CZPT permits the extension rod and the piston rod to connect to every single other very easily and reliably.
e) The Extension Rod Packing The extension rod packing is duplex seal construction to provide the great seal consequence.
f) The Electrical power End The electricity finish uses the blended lubricating system of compelled lubrication and splash lubrication.
one.2 Fluid End Attributes
a) Cylinders Cylinders are created of solid alloy steel, 3 cylinders of every single pump are interchangeable. Valve-more than-valve (through kind cylinder) design and style lowers the cylinder volume and encourages the volumetric performance. At clients request, the cylinder area may possibly be nickel plated to improve the abrasion resistance.
b) Discharge pulsation dampener, shear reduction valve and discharge strainer are furnished at the outlet. F-1300 and F-1600 pump suction inlet is furnished with Φ305 flange.
c) Valve Assembly The suction valve and the discharge valve for F-1300 and F-1600 mud pumps are interchangeable.
F-1300 and F-1600 mud pump makes use of API 7#valve pots.
d) Liners Bi-metallic liners are utilised. The sleeve is manufactured of use-resistant solid iron, the surface area hardness is HRC60~sixty five. For that reason, liners feature dress in resistance, corrosion resistance and large surface finish. Liners are set in from the liner chamber in the entrance of the frame and mounted with liner thread ring , liner lock ,bolt and put on plate when putting in.
e) Pistons And Piston Rods They are slide equipped, sealed with rubber seal ring and lastly mounted with lock nuts to stop the piston from looseness and to play a role in sealing. Cylinders, liners, pistons, valves, valve seats, valve springs, seal rings, valve pot covers, thread rings and cylinder heads at the fluid stop of F-1300 and F-1600 mud pumps are all interchangeable.
f) Spraying Program The spraying technique is made up mainly of spray pump, CZPT water box, and spray pipe, the operate is to great and rinse liners and pistons to encourage their support life. The centrifugal spray pump CZPT driven by a sheave mounted on the input shaft extension conclude or a separate motor and cooled and lubricated by drinking water. The resilient set spray CZPT is utilized. The spray CZPT is mounted on the liner end cover and the body. Nozzle is confront to the piston conclude so that the lubricatingcooling fluid can rinse the get in touch with surface amongst the piston and liner all the time.
g) Lubricating Technique The power stop employs the mixed lubricating program of Charles Rig Supplies, Inc. pressured lubrication and splash lubrication. The strain oil is conveyed through lubricating pipeline, crosshead, extension rod, crosshead CZPT and all bearings by a gear oil pump inside the oil box to recognize the compelled lubrication. The operating situation of the equipment oil pump might be recognized from the strain gauge behind the frame.
h) Charging System To avoid the air lock transpiring for reduced pump inlet stress, each mud pump ought to be furnished with a complete charging method. It is made up of charging pump,pump foundation, butterfly valve and corresponding manifold. Mounted on the suction manifold of the mud pump, the charging pump is pushed by the particular function motor or the enter shaft of the mud pump through V-belts to reduce the energy consumption.
Hebel Xihu (West Lake) Dis.fa Petroleum CZPT Co. LTD was recognized in 2006,with 5000m2 plant.The company focuses on R&D of mud pump fittings and many R&D final results were horned with awards as nicely as patented for creation. The firm is engaged in product design and style, manufacturing and services on all the quality oilfield replacement elements, which includes mud pump fluid end elements like Fluid end modules, liners, pistons, valves,&seats, extension rods, piston rods, valve covers etc.
The organization holds a professional technological team and is outfitted with superior machineries,bettering the technological skills and updating merchandise good quality,
Our products are accredited by ISO9001 good quality handle. We source merchandise not only our oilfields company of domestic, but also dozens of nations all more than the entire world, this sort of as Usa, Canada, Indonesia and Iran. With many years’ persistence, we are broadly recognized as a professional supplier of high high quality mud pump cylinder liners and other parts in fluid stop modules
The effectiveness of a worm equipment transmission depends to a big extent on the helix angle of the worm. Multi-threaded worms and gears with greater helix angles have proven to be 25% to fifty% more efficient than one-threaded worms. The sliding action of the worm meshing with or meshing with the worm gear outcomes in substantial friction and reduction of efficiency when compared to other sorts of gears. Boost performance with hardened and floor worm swap bronze worm gears.
