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.
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%.
