摘要： The present invention discloses a Fluid End and its manufacturing method. The conventional fluid end manufacturing methods involve machining of all surfaces. This demands more input stock for manufacturing process and a lot of material wastage during machining process. In the conventional processes involving open die forging followed by machining result into only about 34% utilization of material. In the present invention, fluid end component geometry is optimized. Assembly surfaces are machined whereas other or non-assembly surfaces are as-forged condition. The method of invention also results in significant reduction in machining time and chip removal. The present invention also discloses a process of manufacturing using a combination of open die and closed die forging, and machining. It involves the steps of cogging an ingot to form billet for closed die forging using open die forging, forging the billet in closed die using forging equipment, semi-finish/rough/partial machining, heat treatment, drilling and finish machining the component. Most of the non-assembly areas of the fluid end are left in as-forged condition.

摘要： A reciprocating pump capable of reducing its overall size by suppressing the size of an entire drive unit. A plurality of piston parts move in the same direction and draw fluid into a plurality of pump chambers and discharge the fluid. The pump chambers are adjacent to each other. A motor has a drive shaft between the centers of piston parts located at both ends in the installation direction of the pump chambers and oriented in a direction substantially orthogonal to the installation direction of the pump chambers and substantially orthogonal to the moving direction of the piston parts. A plurality of cams are aligned adjacent each other in the axial direction on the motor drive shaft. The cams are linked to the piston parts so that the cams cause the reciprocal movement of the piston parts.

摘要： A reciprocating compressor or pump features a manifold arranged not only to define a hollow interior for receiving fluid discharged from a plurality of cylinders but also to define a base or frame on which the cylinders are carried. Unique valves formed in part by flexible material reduces the likelihood of fatigue and increases efficiency by retaining less heat relative to conventional reed valves. A compressor or pump mounted at an end of a handle extending parallel to a motor housing likewise extending from the compressor or pump provides an easy to carry portable assembly. A fan mounted between a motor and a compressor pulls air through the compressor inlet to both cool the motor and feed the compressor. A portable tool system powers both pneumatic and electric tools. Connecting rod structures for radial compressors or pumps provide improved strength and easier assembly.

摘要： The Compressor comprises three stages of compression, having three cylinders, each of the latter having a piston reciprocable therein. Two of the pistons are in-line along a common axis, and the cylinders therefor are in confronting relationship. The third cylinder lies along an axis which traverses the two-piston axis. All three pistons are reciprocated by two connecting rods, in that the in-line pistons are joined by tie rods. Both connecting rods are coupled to the single crank of a crankshaft which is journalled in a crankcase, and all three cylinders are removably bolted to the crankcase.
