The crosshead is an essential component of a high-pressure plunger pump, serving as a connection point between the connecting rod and the plunger.

Products Description

The crosshead is typically a sturdy metal assembly consisting of a crosshead body and attachment points for the connecting rod and plunger. It is designed to withstand high loads and repeated stresses encountered during pump operation. The crosshead may incorporate features such as bearings or bushings to facilitate smooth movement and minimize friction.

Feature

Guides Reciprocating Motion: The primary function of the crosshead is to guide the reciprocating motion of the connecting rod and ensure smooth operation of the pump. It allows the connecting rod to move back and forth in a straight line, transmitting motion from the crankshaft to the plunger without lateral deflection.

Supports Loads: The crosshead supports the loads imposed by the reciprocating motion of the connecting rod and plunger, distributing them evenly to prevent excessive wear and stress on individual components. It helps to maintain proper alignment and stability, ensuring reliable pump operation.

Minimizes Friction: The crosshead may incorporate bearings or bushings to reduce friction between moving parts, facilitating smooth movement and reducing wear. This helps to extend the service life of the pump and improve overall efficiency.

Facilitates Maintenance: The design of the crosshead may include features such as lubrication points or access ports to facilitate maintenance and inspection of the pump assembly. This allows for easy lubrication of moving parts and periodic inspection to ensure proper functioning.
