    During the use of the swing hydraulic cylinder, many factors will affect the piston and affect the work of the cylinder. So, how can we not affect the piston operation of the swing hydraulic cylinder?
    In order to prevent the piston from colliding with the cylinder head at both ends of the stroke, generating noise, affecting the accuracy of the workpiece and even damaging the machine parts, buffer devices are often provided at both ends of the hydraulic cylinder in the hydraulic pump station system. Its role is to use the throttling principle of oil to achieve the braking of moving parts. Commonly used buffer devices include ring gap type, 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 piston speed. Because the mating clearance is unchanged, the cushioning effect is not adjustable, and its cushioning effect gradually weakens as the piston speed decreases.
    2. Adjustable throttle: When the buffer plunger enters the inner hole on the cylinder head, the hydraulic oil must be discharged through the throttle. Because the throttle 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 cross-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 that the cushioning effect is too weak in the later stage of the stroke.
    Buffer device: gap buffer, throttling buffer, axial triangular groove buffer.
    Exhaust of hydraulic cylinders in a hydraulic pumping station system. For hydraulic cylinders that have not been used for a long time or newly purchased hydraulic cylinders, air is often accumulated in high parts of the cylinder. The presence of air will cause the hydraulic pump station system to move erratically, causing vibration or crawling. To this end, an exhaust device is required on the hydraulic cylinder.
    There are usually two types of exhaust devices: one is to open the exhaust hole at the high part of the hydraulic cylinder and use a long pipe to exhaust the exhaust valve at a distance; Exhaust valve, for the double-acting hydraulic pumping station system hydraulic cylinder should be provided with 2 exhaust valves.
    The above is the method to ensure the normal operation of the swing cylinder piston, I hope to help you.
