The power end is mainly composed of frame, crank shaft, pinion shaft, crosshead and extension rod.
Features of power end:
1. The crankshafts are driven by herringbone gear without tooling withdrawal groove.
2. Crankshafts are made of alloy steel.
3. Crosshead guiding plates are changeable.
4. ·Frames are of high strength, supreme rigidity and light weight for the adoption of welded steel plate parts .
5. The extention rod adopts double dealing structure with excellent sealing effect.
6. The combination of the forced lubrication and splash lubrication applied for the power end.
Hydraulic cylinders, valve assembly , liners and pistons are the major components of the fluid end .
Features of hydraulic end:
1. Sealing parts are impacted in rigid with good sealing.
2. Upright hydraulic cylinder obtains excellent suction performance..
3. L-shaped hydraulic cylinder has the advantage of supreme compression resistance and convenience of replacing valve assembly.
Hydraulic cylinder
Hydraulic cylinder is forged of alloy steel. Three cylinders of one pump are interchangeable with each other. According to customers’ special requirements, to enhance the anti-corrosion performance, the surface of the hydraulic cylinder is supposed to be processed with chemical plating nickel. Pulsation dampener, shear relief valve and discharge strainer are separately mounted on the outlet.
Valve assembly
The suction valves and discharge valves of RLF mud pump are interchangeable with each other.
Liner
The suction valves and discharge valves of RLF mud pump are interchangeable with each other.
Spray pump
This system is consisted of spray pump, cooling water tank and spray pipelines with the function of the necessary cooling and splashing to liners and pistons to prolong their lifetime.
The splashing pump is the centrifugal pump which can be driven by the belt mounted on the end of input shaft, or can be individually driven by a motor with water as the cooling and lubrication media.
To wash the interface between the pistons and liners back and forth , the fixed spray pipelines are employed which are secured inside the shell.
Lubrication system
The combination of forced lubrication and splashing lubrication is used for the power end. For the purpose of forced lubrication, the gear oil pump located at the oil tank feeds compressed oil to crossheads, extension rods and bearings respectively via the lubrication pipe lines. More ever, the operation situation of the gear oil pump can be observed by the manometer embedded in the after body of mud pumps.
Charging system
Each mud pump can be equipped with one charging pump to avoid air blocking caused by low pressure at the suction inlet. The spray system is driven by a special motor which is installed on the suction pipe assembly. To reduce the total power supply of drilling rigs, driving shaft is employed to drive the spray pump as well.
