Merchandise Application

1 Framework Functions
one.1 Energy End Functions
a) The Frame The body is manufactured of welded steel plate and tension aid treated to receive the great rigidity and substantial power. The area in which the crankshaft bearing is equipped is strengthened by using ribbed plates. The body is furnished with the necessary oil basin and oil way technique for 

cooling and lubricating purpose.
b) The Pinion Shaft The pinion shaft is created of cast alloy steel on which a herringbone gear with the medium-hard tooth surface is machined. For easy routine maintenance, the solitary row radial extended cylindrical roller bearing with internal ring(without sides) is used. The both ends of the pinion shaft increase out, so that the sheave or the sprocket can be mounted on both conclude.
c) The Crankshaft The crankshaft is created of ca EPT alloy metal and furnished with herringbone gear, connecting rod and bearing. The tooth type of the huge-geared ring is herringbone equipment. The gear bore and the crankshaft surfaces are interference equipped and they are the two fastened with bolts and lock nuts. The huge conclude of the connecting rod is mounted on 3 eccentric straps of the crankshaft by means of solitary row brief cylindrical roller bearings and the small stop on the crosshead pin via double row extended cylindrical roller bearing. Double row radial spherical roller bearings are mounted at equally finishes of the crankshaft.
d) The Crosshead And Crosshead Xihu (We EPT Lake) Dis. The crosshead and crosshead guide are made of homebred meehanite ca EPT iron showcased by very good abrasion resistance and prolonged service lifestyle. Upper and lower guides are used for mud pump, so that the concentricity can be altered by incorporating shims beneath the reduce guidebook. The relationship between the crosshead and the extension rod is produced by utilizing bolted flange. The rigid connection makes certain the concentricity of the crosshead and the extension rod. The coupling is used for connecting the extension rod to the piston rod. The gentle-fat coupling permits the extension rod and the piston rod to hook up to each EPT simply and reliably.
e) The Extension Rod Packing The extension rod packing is duplex seal construction to provide the good seal outcome.
f) The Electrical power Finish The electrical power finish utilizes the mixed lubricating method of forced lubrication and splash lubrication.
one.2 Fluid Conclude Features
a) Cylinders Cylinders are created of solid alloy steel, 3 cylinders of each pump are interchangeable. Valve-above-valve (by means of type cylinder) layout decreases the cylinder volume and promotes the volumetric effectiveness. At buyers request, the cylinder area could be nickel plated to boost 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 employs API 7#valve pots.
d) Liners Bi-metal liners are utilised. The sleeve is created of dress in-resistant ca EPT iron, the area hardness is HRC60~sixty five. For that reason, liners function put on resistance, corrosion resistance and substantial area complete. Liners are place in from the liner chamber in the EPT of the frame and set 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 ultimately fixed with lock nuts to avert 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 finish of F-1300 and F-1600 mud pumps are all interchangeable.
f) Spraying Technique The spraying program consists primarily of spray pump, cooling water box, and spray pipe, the function is to amazing and rinse liners and pistons to encourage their service daily life. The centrifugal spray pump can be pushed by a sheave mounted on the input shaft extension conclude or a separate motor and cooled and lubricated by h2o. The durable fixed spray pipe is utilised. The spray pipe is mounted on the liner end cover and the frame. Nozzle is experience to the piston stop so that the lubricatingcooling fluid can rinse the get in touch with surface area among the piston and liner all the time.
g) Lubricating Program The electricity end makes use of the merged lubricating program of Charles Rig Provides, Inc. pressured lubrication and splash lubrication. The strain oil is conveyed by way of lubricating pipeline, crosshead, extension rod, crosshead guidebook and all bearings by a gear oil pump in the oil box to recognize the compelled lubrication. The working problem of the gear oil pump may possibly be understood from the stress gauge driving the frame.
h) Charging Program To avert the air lock happening for low pump inlet force, every mud pump must be furnished with a complete charging program. 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 driven by the particular goal motor or the enter shaft of the mud pump by way of V-belts to minimize the power usage.

Organization profile

Hebel Xihu (We EPT Lake) Dis.fa Petroleum EPT Co. L EPT was proven in 2006,with 5000m2 plant.The business focuses on R&D of mud pump fittings and many R&D outcomes were horned with awards as nicely as patented for invention. The company is engaged in item style, producing and services on all the top quality oilfield alternative areas, like mud pump fluid finish parts such as Fluid stop modules, liners, pistons, valves,&seats, extension rods, piston rods, valve covers and so forth. 
The firm retains a professional complex group and is geared up with innovative machineries,improving the specialized skil EPT and updating item quality,
