(Colombia hydraulic shear cylinder,produced by Hebei Hengyu company）

hydraulic shear cylinder are widely used in Colombia，because of excellent temperature resistance，no transmission clearance，powerful torque.So our company has designed hydraulic shear cylinder for customers from Colombia.

Introduction to hydraulic shear cylinder:

The hydraulic shear cylinder should be vented: when the hydraulic shear cylinder is installed or parked for a long time to work again, the air will penetrate into the hydraulic shear cylinder and the pipeline system. In order to prevent the abnormal phenomenon of crawling, noise and heating of the actuator, the air in the hydraulic shear cylinder and the system should be discharged. In order to facilitate the removal of air deposited in the hydraulic shear cylinder, the oil is best entered and discharged from the highest point of the hydraulic shear cylinder. hydraulic shear cylinders that require higher motion stability are often equipped with exhaust plugs at both ends. Before working, unscrew the exhaust plug to make the piston go back and forth several times without load in the whole stroke, and the air can be discharged through the exhaust plug. After the air is drained, tighten the exhaust plug before working.

When producing oil hydraulic shear cylinders, there are two processing processes, grinding and rolling, the latter is better than the former. Rolling machining is a kind of non-cutting machining, using the plastic deformation of the metal at room temperature, so that the micro roughness of the workpiece surface is flattened to achieve the purpose of changing the surface structure, mechanical characteristics, shape and size. Therefore, this method can achieve the two purposes of finishing and strengthening at the same time, which can not be done by grinding.

The oil hydraulic shear cylinder is a part of the hydraulic system, in the hydraulic system, to reasonably design the heat dissipation system, to prevent the oil temperature is too high is the key to keep the hydraulic oil temperature normal. The temperature of the system should be kept in a suitable range to reduce the energy released when the bubble bursts. While not affecting the normal circulation of the coolant, a certain amount of anti-corrosion additives can be appropriately added to inhibit rust. When operating the hydraulic system, we should strive to be stable, not too fast, too strong, and try to reduce the impact of hydraulic oil on hydraulic components.

The definition of the minimum starting pressure of the hydraulic shear cylinder refers to the minimum working pressure of the hydraulic shear cylinder in the no-load state, which is a comprehensive index reflecting the manufacturing and assembly accuracy of the hydraulic shear cylinder parts and the size of the sealing friction.

Answers to some questions about hydraulic shear cylinder:

Why is a light cylinder less productive than a heavy cylinder at the same oil pressure?
f=ps Under the same pressure, the larger the area, the greater the output, but the maximum pressure can not exceed the system engineering pressure of the cylinder!

Why is the cylinder not in place when the concrete pump truck changes the piston?
When the concrete pump truck changes the piston, the cylinder is not in place mainly because the transfer oil connecting the two cylinders is not completely drained. Sany and Zhonglian have a piston return switch, which can be used to back the piston to the cleaning tank. The elephant is equipped with a stop valve at the bottom of the oil cylinder, usually in the closed state, when opened, the piston can be returned to the cleaning tank, remember to close the valve after the piston is updated.
