The main parts of a three-cylinder single-acting power end include a crankshaft, power end case, cross-head, connecting rod, and joint rod as well as bearing
The power end adopts two support structures, it is the frame that carries the crankshaft and cross-head for normal operation, and the piston cylinder is also fixed on the power end case. The piston thrust on the diaphragm and the crankshaft by the reaction force of the connecting rod are absorbed by the power end unit. This requires the power end box to have high strength and impact resistance,
Structure Introduction: The power end housing is a one-piece casting structure. The crankshaft and the box body adopt two support structures, which greatly simplifies the maintenance work of the power end. The bearing cover and seat are connected with dynamic load pre-stressing studs. The thread of the stud is milled, and the mechanical property reaches 10.9 grade with reliable strength.
Power End Case Box
①Compared with the structural part box, the cast box is suitable for mass production, and the production quality and production cycle can be easily guaranteed.
②The ductile iron of the same grade as the wind power booster box body is chosen as the material of the power end box body.
③The casting box body of ductile iron material has sufficient rigidity, shock, and impact resistance, which can prevent deformation and ensure transmission quality.
④Cast box body of ductile iron material has almost no internal stress during the casting process, and simple aging treatment can eliminate the internal stress.
⑤ Compared with the welded box, the casting box does not have any welding work, which fundamentally avoids the contradiction between quality control and production cycle and manufacturing cost caused by a large amount of welding work.
In short, the cast power end box is better than the welded box in several aspects, such as seismic resistance, impact resistance, the concentration of internal stress, quality control, production cycle, and cost contradiction.
Crankshaft Structure Introduction:
The crankshaft adopts the three-inflection and two-support structure, which consists of the input end, three crankshafts, and two orthocentric shafts, i.e. the three-inflection and two-support structure with one forging and molding.
①The advantage of two supports at both ends.
Heavy Pump has reasonably allocated the clearance of the crankshaft bearings, constituting a supported layout with both sides supported mainly and the middle support supplemented, which solves the problem of static instability brought about by four supports. At the same time, the crankshaft deflection will work within the range allowed by the design, thus obtaining a stable and reliable transmission system with strong and weak supports complementing each other.

Heavy Pump has reasonably allocated the clearance of the crankshaft bearings, constituting a supported layout with both sides supported mainly and the middle support supplemented, which solves the problem of static instability brought about by four supports. At the same time, the crankshaft deflection will work within the range allowed by the design, so as to get a stable and reliable transmission system with strong and weak supports complementing each other.
②The crankshaft material is high-strength electro-slag remelting alloy steel. Electroslag remelting alloy steel generally has no defects such as shrinkage, loosening, inclusions gathering, macroscopic segregation, etc. It has high tissue denseness, uniform composition, low impurity content, and stable quality. These characteristics are particularly important in process industries such as tailing workers, which have high requirements for the continuous operation rate of the equipment.
③The connecting rod bearing adopts reasonable bearing clearance control technology, which can reduce the impact on the bearing when working.
