How to not affect the piston of the hydraulic boom cylinder

  

In order to prevent the piston from colliding with the cylinder head at both ends of the stroke, which will produce noise, affect the accuracy of the workpiece and even damage the parts, buffer devices are often set at the two ends of the hydraulic boom cylinder in the hydraulic pump station system. Its role is to use the throttling principle of the oil to achieve the braking of moving parts. Commonly used buffer devices include ring gap, adjustable orifice, and variable orifice.

 

1. Ring gap type: When the buffer plunger enters the inner hole of the matching cylinder head, the hydraulic oil must be discharged through the gap to reduce the speed of the piston. Because the mating clearance remains the same, the cushioning effect is not adjustable, and as the piston speed decreases, its cushioning effect gradually decreases.

 

2. Adjustable throttle: When the buffer plunger enters the inner hole on the cylinder head, the hydraulic oil must pass through the throttle to be discharged. Because the throttle valve is adjustable, the buffering effect is also adjustable, but this adjustment is the adjustment before the buffering is performed. During the buffering, the buffering effect is still fixed.

  

3. Throttle variable type: There is a triangular groove in the axial direction of the piston, and its over-flow section is getting smaller and smaller, and the buffering effect is enhanced as the speed decreases. The cushioning effect is uniform, the cushioning pressure is low, and the braking position accuracy is high, which solves the problem of too weak cushioning effect in the final stage of the stroke.

  

Buffer device: gap buffer, throttling buffer, axial triangular groove buffer.

  

Exhaust of hydraulic boom cylinder in hydraulic pumping station system. For long-term unused hydraulic boom cylinders or newly purchased hydraulic boom cylinders, air is often accumulated in the highest part of the cylinder. The presence of air will cause the pump system to move erratically, causing vibration or crawling. To this end, an exhaust device is required on the hydraulic boom cylinder.
