Algeria self-locking hydraulic cylinder

(Algeria self-locking hydraulic cylinder,produced by Hebei Hengyu company)

self-locking hydraulic cylinder are widely used in Algeria,because of no transmission clearance,powerful torque,clever hydraulic energy conversion.So our company has designed self-locking hydraulic cylinder for customers from Algeria.

Introduction to self-locking hydraulic cylinder:

The self-locking hydraulic cylinder should be vented: when the self-locking hydraulic cylinder is installed or parked for a long time to work again, the air will penetrate into the self-locking hydraulic cylinder and the pipeline system. In order to prevent the abnormal phenomenon of crawling, noise and heating of the actuator, the air in the self-locking hydraulic cylinder and the system should be discharged. In order to facilitate the removal of air deposited in the self-locking hydraulic cylinder, the oil is best entered and discharged from the highest point of the self-locking hydraulic cylinder. self-locking hydraulic 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 self-locking hydraulic 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.

self-locking hydraulic cylinder and hydraulic station selection: Select the type and structure of the self-locking hydraulic cylinder according to the operation requirements of the main engine. According to the external load force borne by the self-locking hydraulic cylinder, such as gravity, friction force of the external mechanism, inertia force and working load, determine the load change law of the self-locking hydraulic cylinder in each stage of the stroke and the power value that must be provided. Determine the diameter of the piston and piston rod according to the working load of the self-locking hydraulic cylinder and the selected oil working pressure. the flow rate of the hydraulic pump is determined according to the movement speed of the self-locking hydraulic cylinder, the diameter of the piston and the piston rod.

The internal leakage of the self-locking hydraulic cylinder is an important indicator to measure the quality of the self-locking hydraulic cylinder: the internal leakage of the self-locking hydraulic cylinder will reduce the volumetric efficiency, increase the temperature rise of the oil, affect the positioning accuracy of the self-locking hydraulic cylinder, so that the self-locking hydraulic cylinder can not accurately and stably stop in a certain position of the self-locking hydraulic cylinder, so it is one of the main indicators of the self-locking hydraulic cylinder.

Answers to some questions about self-locking hydraulic cylinder:

Can pneumatic cylinder be used as hydraulic cylinder?
The pneumatic cylinder can only be used for pressure below 1MPA, and if it is used for hydraulic, the pressure should be under 1MPA, which may not meet the strength requirements. And the seals should use fluorine rubber to avoid corrosion. But pneumatic cylinder used as hydraulic cylinder is not whimsical, in fact, there is such a use. The pneumatic system has a natural defect, that is, the speed is unstable, especially in the case of low speed. The hydraulic pressure is very stable, if you do not want to buy a set of hydraulic system, while the strength of the cylinder is not large, you can use compressed air to push the hydraulic oil, with hydraulic oil to drive the cylinder, The force is the same as compressed air, but very smooth.

By what means can the hydraulic system control the arbitrary stroke position of the rotary cylinder piston rod?
The following ways can be considered: 1, through the limit device, such as limit switch, position sensor, etc. 2, by feedback the pressure of the hydraulic oil in the cylinder. The load determines the pressure, the pressure in the cylinder is determined by the load, and the pressure is very small when the cylinder is unloaded. 2.1 When clamping the workpiece, the pressure of the cylinder increases, by calculating the relationship between the clamping force and the pressure of the cylinder, take a pressure value of the cylinder, set the pressure switch, and drive the valve to work when the pressure reaches the preset value, so that the oil circuit stops supplying oil. 2.2 or set the pressure value of the relief valve to overflow after a certain set pressure.
