Description

Technical Field

[0001] This utility model relates to the field of water pump connecting rod technology, and in particular to a high-strength water pump connecting rod. Background Technology

[0002] The connecting rod is a key component in a piston water pump, used to convert the reciprocating motion of the piston into the rotational motion of the crankshaft. It needs to withstand alternating loads from fluid forces, inertial forces, and rotational inertial forces, therefore it must have sufficient strength and rigidity while minimizing its mass.

[0003] However, the existing technology still has shortcomings. In the existing technology, the swing arm and the base are only fixed by bolts. Since the connecting rod needs to withstand high strength and frequent stress changes during the operation of the water pump, the connection of the connecting rod is prone to deformation, which reduces the stability of the connecting rod in long-term use.

[0004] Therefore, we propose a high-strength water pump connecting rod to solve this problem. Utility Model Content
