W-44O/446 TRIPLEX MUD PUMP

W-440/446 Mud Pumps can be widely used in all types of operation in oil & gas drilling field. The liner sizes range from 3 1/2”to6”, which are suitable to adopt piston structure for well maintenance and shallow well drilling. The pumps with liner size of2”to 3 1/4”adopts plunger structure for high pressure. This pump is compact in structure, small volume, light weight, integral herringbone gear struture, large transmission torque and smooth running.

The design of the pump W-440/446 has the following advantages:

Frame-

The machine frames are welded with steel plates and processed to eliminate stress after welding. Therefore, there ae reinforced plates at the seats of crankshaft and the main bearing, so that they have good stiffness and strength.

Crankshaft-

The crankshaft is in a balanced structure with welded forged parts. It is light and can be operated smoothly without vibration. The both sides of the crankshaft are equipped with double aligning sperical roller bearings so as to ensure the stability in operation and to improve its bearing capacity.

Pinion shaft-

It is made of forged alloy steel, herringbone gears(integral) is machined on the shaft and it adopts medium hard tooth surface. There is shaft extension at both ends,  where bell pulleys or chain wheels may be installed.

Crosshead-

The crosshead is made by one-piece cast with nodular cast iron, so the crosshead has good resistance abrasion. The structure of upper and lower guide is adopted for crossheads in order to regulate the concentricity by adding space at the lower guide. The extension rods are connected to the crossheads by the flange bolts with pin holes, so as to ensure the concentricity of the crosshead and the extension rods. The packing adopts double layer sealing structure, which realizes a good seal performance.

Fluid Cylinder-

The cylinder is made of forged alloy steel and adopts a straight-way structure. The hydraulic cyliner has a small size and higher volume efficiency. The cylinder surface is processed by chemical plating in order to increase the resistance corrosion. The three hydraulic cylinder are interchangeable.

Liner-

W440/446 pumps have the same liner OD. The liner are mounted tightly on the end face of hydraulic cylinder by using squareness capping and bolts. Sealing between the liner and the hydraulic cylinder is realized by rectangular rubber gaskets.

Lubrication system-

The pump adopts forced lubrication. In the oil tank, there is a gear oil pump, which transmits pressure oil to the crosshead guide as well as the bearings, so as to realize forced lubricating and cooling.
