AH1301010401 Mud Pump Crosshead

What is Bomco Mud Pump Crosshead?

Crosshead is a system which creates linear reciprocating motion derived from the crankshaft’s rotary motion through the connecting rod. The reciprocating motion of the crosshead is applied to the piston via the extension rod.

A crosshead is a mechanism used in large reciprocating engines to eliminate sideways pressure on the piston. The crosshead of mud pump produced by our company is made of high quality wear resistant with special techniques. It features little deformation, higher precision and very little tolerance.

The crosshead is the critical part on the power end of the mud pump. It slides in the upper and lower guide plates, motivating the intermediate draw bar to deliver driving force to the hydraulic end. One of its ends fixes the intermediate draw bar. The cavity connects the small end of the connecting rod through cross head pin.

What is the material of the crosshead?

The material of the crosshead is nodular cast iron with the strength of extension of more than 600MPa, which ensures high intensity and abrasive resistance.

The difference between crossheads in metric system and British system is the screw hole.

To guarantee close contact, the contact area of bore-hole of the crosshead and the conical surface of the crosshead pin shall be greater than 75%.

What are the features of Bomco Mud Pump Crosshead?

Crosshead has high accuracy and precious dimension and no deformation. Besides F-500 mud pump that is cylindrical structure, upper and lower guide structures are used for other mud pumps, so that the concentricity can be adjusted by adding space under the lower guide. Flange-bolts with pinhole fit are used for connecting crosshead to extension rod.

The mode of mud pump from BOMCO, Rongsheng, HongHua, F500 mud pump, F1000 mud pump, F1300 mud pump, F1600 mud pump.
