Oilfield Parts/Energy Stop Parts/connecting rod
1 Construction Characteristics
1.1 Electrical power Stop Characteristics
a) The Frame The body is made of welded metal plate and pressure reduction taken care of to receive the great rigidity and large power. The location exactly where the crankshaft bearing is fitted is strengthened by making use of ribbed plates. The body is furnished with the necessary oil basin and oil way technique for
cooling and lubricating objective.
b) The Pinion Shaft The pinion shaft is produced of forged alloy steel on which a herringbone gear with the medium-hard tooth floor is machined. For easy servicing, the solitary row radial long cylindrical roller bearing with interior ring(without sides) is utilised. The each finishes of the pinion shaft prolong out, so that the sheave or the sprocket CZPT mounted on possibly end.
c) The Crankshaft The crankshaft is produced of forged alloy steel and furnished with herringbone gear, connecting rod and bearing. The tooth kind of the massive-geared ring is herringbone equipment. The gear bore and the crankshaft surfaces are interference equipped and they are each fixed with bolts and lock nuts. The big stop of the connecting rod is mounted on 3 eccentric straps of the crankshaft by means of solitary row brief cylindrical roller bearings and the tiny conclude on the crosshead pin through double row extended cylindrical roller bearing. Double row radial spherical roller bearings are mounted at each ends of the crankshaft.
d) The Crosshead And Crosshead Xihu (West Lake) Dis. The crosshead and crosshead CZPT are created of homebred meehanite cast iron showcased by great abrasion resistance and prolonged provider daily life. Higher and reduce guides are used for mud pump, so that the concentricity CZPT adjusted by introducing shims beneath the reduce manual. The link amongst the crosshead and the extension rod is created by employing bolted flange. The rigid connection ensures the concentricity of the crosshead and the extension rod. The CZPT is used for connecting the extension rod to the piston rod. The mild-fat CZPT allows the extension rod and the piston rod to hook up to each other easily and reliably.
e) The Extension Rod Packing The extension rod packing is duplex seal construction to offer the great seal result.
f) The Power Stop The electricity conclude utilizes the blended lubricating program of pressured lubrication and splash lubrication.
1.2 Fluid Finish Functions
a) Cylinders Cylinders are manufactured of forged alloy metal, 3 cylinders of each and every pump are interchangeable. Valve-more than-valve (through kind cylinder) style decreases the cylinder volume and promotes the volumetric effectiveness. At buyers request, the cylinder surface may be nickel plated to improve the abrasion resistance.
b) Discharge pulsation dampener, shear aid 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-steel liners are used. The sleeve is created of dress in-resistant solid iron, the area hardness is HRC60~sixty five. Consequently, liners attribute wear resistance, corrosion resistance and substantial surface end. Liners are set in from the liner chamber in the entrance of the frame and fastened with liner thread ring , liner lock ,bolt and dress in plate when installing.
e) Pistons And Piston Rods They are slide equipped, sealed with rubber seal ring and last but not least fixed with lock nuts to stop the piston from looseness and to enjoy a role in sealing. Cylinders, liners, pistons, valves, valve seats, valve springs, seal rings, valve pot addresses, thread rings and cylinder heads at the fluid stop of F-1300 and F-1600 mud pumps are all interchangeable.
f) Spraying Technique The spraying technique is made up mostly of spray pump, CZPT water box, and spray pipe, the function is to amazing and rinse liners and pistons to market their support existence. The centrifugal spray pump CZPT pushed by a sheave mounted on the input shaft extension conclude or a separate motor and cooled and lubricated by h2o. The resilient set spray CZPT is utilised. The spray CZPT is mounted on the liner conclude include and the body. Nozzle is face to the piston end so that the lubricatingcooling fluid can rinse the contact surface amongst the piston and liner all the time.
g) Lubricating Program The electrical power finish makes use of the blended lubricating system of Charles Rig Supplies, Inc. forced lubrication and splash lubrication. The stress oil is conveyed via lubricating pipeline, crosshead, extension rod, crosshead CZPT and all bearings by a gear oil pump within the oil box to comprehend the compelled lubrication. The working problem of the gear oil pump may be recognized from the stress gauge driving the frame.
h) Charging Technique To stop the air lock transpiring for minimal pump inlet pressure, every mud pump must be furnished with a complete charging program. It consists of charging pump,pump base, butterfly valve and corresponding manifold. Mounted on the suction manifold of the mud pump, the charging pump is driven by the special purpose motor or the enter shaft of the mud pump by way of V-belts to reduce the electrical power usage.
