ZN Damping Cylinder

1. the cylinder bore is the same as the SC and SU series cylinder bore standard.

2. ZN damping cylinder, also known as gas-hydraulic speed stabilization cylinder, damping cylinder and hydraulic brake cylinder, is injected with hydraulic oil in the internal structure of the cylinder, using internal oil damping adjustable structure, piston rod extension and return speed is adjustable respectively, movement balance, reasonable structure, reliable performance, so as to achieve the uniform speed movement of the cylinder, no large impact of the cylinder.

3. The piston rod extends out to adjust the speed, and the piston rod returns to the adjustable speed.

4. This series of damping cylinders has an oil cylinder, which needs to be used together with the cylinder to form an air-liquid damping cylinder to obtain smooth movement using the cylinder, which is more widely used in the feed drive device.

5. The hydraulic brake cylinder has two different control methods: 1. The piston rod with adjustable speed extends and returns quickly; 2. The piston rod quickly extends and returns at adjustable speed. The brake cylinders are equipped with a small compensating fuel tank to ensure that the oil volume is automatically balanced.

1. The flow control valve on the hydraulic brake cylinder can adjust the speed of the piston rod. Brake cylinders with built-in jump valves and brake valves can be supplied according to customer requirements to realize their jump and stop functions.

When the oil in the tank reaches a small scale, it is necessary to replenish it, please use No. 40 oil and the corresponding pump.

2. It is suitable for occasions that require the cylinder to move slowly and evenly.

3. The cylinder uses compressible air as the working medium, the action is fast, but the speed stability is poor, and when the load changes greatly, it is easy to produce crawling or "self-propelled phenomenon." In addition, the pressure of the compressed air is low, so the output force of the cylinder is small. To this end, a combination of cylinder and oil cylinder is often used to form a variety of gas-hydraulic combined actuators to achieve the purpose of controlling the speed or increasing the output force.

The gas-hydraulic damping cylinder uses the cylinder to drive the cylinder, in addition to the damping effect, it can also increase the rigidity of the cylinder (because the oil is incompressible), and play the advantages of stable hydraulic transmission and uniform transmission speed

4. Commonly used in the feed drive device of machine tools and cutting devices. Common are SC type, SU type, SC type new, SU type new meter resistance with series, parallel gas-liquid damping cylinder. Taking the tandem type as an example, it uses a piston rod to string the two pistons together, and the cylinder and the cylinder are separated by a partition to prevent gas from being strung into the cylinder. When the left end of the cylinder is intake, the cylinder will overcome the load resistance, drive the cylinder to the right, and adjust the throttle valve opening to change the movement speed of the damping cylinder piston.
