• 295-9433 2959433 Barrel Excavator Hydraulic Pump Fitting For 374D L 374F L 390F L

• Specification

• Function

1.Forming a Sealed Chamber: The barrel is a seamless cylindrical part that, together with the piston and cylinder head, forms a sealed chamber. This chamber is used to hold hydraulic fluid. When hydraulic fluid is pumped into the chamber through the inlet port under pressure, it creates a pressure environment that acts on the piston.

2.Converting Fluid Power into Linear Motion: The pressure of the hydraulic fluid in the barrel pushes against the piston, causing the rod attached to the piston to extend or retract. This converts the hydraulic energy of the fluid into linear mechanical motion, which is used to power various components in construction equipment, such as lifting heavy objects, pushing or pulling loads, and performing digging operations.

3.Withstanding Load and Shock: During the operation of the hydraulic cylinder, the barrel needs to withstand cyclic loading and repeated shocks. It is made of high - strength materials to minimize the risk of fatigue failure, ensuring the reliability and durability of the hydraulic cylinder under harsh working conditions.
