connecting rod/Petro CZPT Mud Pump Spare Areas
one Structure Features
1.1 Electrical power Finish Characteristics
a) The Frame The body is manufactured of welded metal plate and anxiety aid handled to receive the very good rigidity and high strength. The location in which the crankshaft bearing is fitted is strengthened by utilizing ribbed plates. The frame is furnished with the necessary oil basin and oil way system for
cooling and lubricating function.
b) The Pinion Shaft The pinion shaft is produced of forged alloy steel on which a herringbone equipment with the medium-challenging tooth area is machined. For straightforward maintenance, the single row radial prolonged cylindrical roller bearing with interior ring(without sides) is employed. The both ends of the pinion shaft increase out, so that the sheave or the sprocket CZPT mounted on either finish.
c) The Crankshaft The crankshaft is made of forged alloy steel and furnished with herringbone equipment, connecting rod and bearing. The tooth kind of the huge-geared ring is herringbone equipment. The gear 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 through one row short cylindrical roller bearings and the tiny stop on the crosshead pin via double row lengthy 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 manufactured of homebred meehanite forged iron showcased by excellent abrasion resistance and long provider lifestyle. Upper and reduce guides are employed for mud pump, so that the concentricity CZPT altered by including shims beneath the reduce information. The relationship amongst the crosshead and the extension rod is manufactured by using bolted flange. The rigid link ensures the concentricity of the crosshead and the extension rod. The CZPT is utilized for connecting the extension rod to the piston rod. The light-weight-weight CZPT enables the extension rod and the piston rod to join to every other very easily and reliably.
e) The Extension Rod Packing The extension rod packing is duplex seal composition to give the excellent seal consequence.
f) The Electrical power Finish The power stop employs the merged lubricating system of pressured lubrication and splash lubrication.
one.2 Fluid End Attributes
a) Cylinders Cylinders are created of solid alloy metal, 3 cylinders of each and every pump are interchangeable. Valve-more than-valve (through variety cylinder) design and style lowers the cylinder volume and encourages the volumetric efficiency. At clients ask for, the cylinder surface area might 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 uses API 7#valve pots.
d) Liners Bi-metallic liners are utilised. The sleeve is produced of dress in-resistant forged iron, the area hardness is HRC60~65. Therefore, liners characteristic dress in resistance, corrosion resistance and substantial floor complete. Liners are place in from the liner chamber in the entrance of the body and mounted with liner thread ring , liner lock ,bolt and dress in plate when putting in.
e) Pistons And Piston Rods They are slide equipped, sealed with rubber seal ring and last but not least fastened 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 addresses, thread rings and cylinder heads at the fluid stop of F-1300 and F-1600 mud pumps are all interchangeable.
f) Spraying Method The spraying system is composed mainly of spray pump, CZPT drinking water box, and spray pipe, the operate is to cool and rinse liners and pistons to market their services existence. 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 durable fastened spray CZPT is utilised. The spray CZPT is mounted on the liner finish include and the frame. Nozzle is confront to the piston conclude so that the lubricatingcooling fluid can rinse the make contact with floor in between the piston and liner all the time.
g) Lubricating Program The electricity conclude makes use of the merged lubricating system of Charles Rig Provides, Inc. forced lubrication and splash lubrication. The pressure oil is conveyed by means of lubricating pipeline, crosshead, extension rod, crosshead CZPT and all bearings by a gear oil pump inside the oil box to realize the pressured lubrication. The operating situation of the equipment oil pump may possibly be recognized from the stress gauge guiding the body.
h) Charging Method To prevent the air lock happening for minimal pump inlet pressure, every single mud pump should 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 via V-belts to decrease the electrical power intake.
Hebel Xihu (West Lake) Dis.fa Petroleum CZPT Co. LTD was set up in 2006,with 5000m2 plant.The organization focuses on R&D of mud pump fittings and a number of R&D final results ended up horned with awards as well as patented for creation. The firm is engaged in product design, production and services on all the top quality oilfield replacement components, including mud pump fluid conclude parts such as Fluid end modules, liners, pistons, valves,&seats, extension rods, piston rods, valve addresses and so forth.
The company holds a professional technical staff and is geared up with sophisticated machineries,enhancing the technological capabilities and updating merchandise good quality,
Our goods are licensed by ISO9001 good quality handle.

The main gain of worm gears is their capability to provide high reduction ratios and correspondingly higher torque multipliers. They can also be utilized as reducers for lower to medium pace purposes. Also, simply because their reduction ratio is primarily based on the quantity of enamel on the gear, they are more compact than other varieties of gears. Like good pitch leadscrews, worm gears are generally self-locking, generating them ideal for hoisting and hoisting apps.
