Libya hydraulic cylinder,vehicle hydraulic cylinder manufacturer,vehicle hydraulic cylinder(Libya vehicle hydraulic cylinder,produced by Hengyu Hydraulic Cylinder Factory)
vehicle hydraulic cylinder are widely used in Libya,because of long service life,no need for deceleration device,smooth movement.So our company has designed vehicle hydraulic cylinder for customers from Libya.
The vehicle hydraulic cylinder should not be mixed with foreign objects during assembly, which will cause scars. Before the total assembly of the vehicle hydraulic cylinder, all parts must be fully removed and cleaned. When the parts are installed with burrs or dirt, foreign objects are easily embedded into the surface of the vehicle hydraulic cylinder wall due to the stiffness and the weight of the parts, causing scars.
The vehicle hydraulic cylinder is mainly composed of body, piston, piston rod, vehicle hydraulic cylinder head, vehicle hydraulic cylinder bottom, piston rod head and related auxiliary devices. The piston divides the vehicle hydraulic cylinder into two chambers, and moves reciprocally in the vehicle hydraulic cylinder with the help of pressure oil. In order to improve its working effect, there is no sealing ring on the piston to eliminate internal leakage, where the piston rod passes through the vehicle hydraulic cylinder head, due to the existence of the gap, it is easy to produce external leakage phenomenon, and the dust can enter the vehicle hydraulic cylinder through the gap, so the sealing device and dust prevention reason are set. At the same time, in order to eliminate the influence of eccentric load on the work of the piston, all the vehicle hydraulic cylinders must be provided with a considerable length of guide sleeve at the extended end of the piston rod. In addition, in the case of faster piston movement, the phenomenon of mechanical collision between the piston and the vehicle hydraulic cylinder bottom and the vehicle hydraulic cylinder head is serious, so the buffer deceleration should be set at both ends of the vehicle hydraulic cylinder The working medium of the vehicle hydraulic cylinder: because it works at room temperature, the ordinary oil-type hydraulic oil can be selected; vehicle hydraulic cylinder sealing device: The use of Yx sealing ring, polyurethane (PU) and polytetrafluoroethylene (PTFE) materials combined to achieve a good sealing effect; Buffer mechanism of the vehicle hydraulic cylinder: The buffer structure of the vehicle hydraulic cylinder is to prevent the piston from colliding with the vehicle hydraulic cylinder head at the end of the stroke.
When the piston speed of the vehicle hydraulic cylinder is high, the steel ball of the check valve flows with the oil flow, so that the valve hole is blocked, and the vehicle hydraulic cylinder moves irregularly. Elimination method: Replace the steel ball with a cone valve or spool with a guide shoulder.
The internal leakage of the vehicle hydraulic cylinder is an important indicator to measure the quality of the vehicle hydraulic cylinder: the internal leakage of the vehicle hydraulic cylinder will reduce the volumetric efficiency, increase the temperature rise of the oil, affect the positioning accuracy of the vehicle hydraulic cylinder, so that the vehicle hydraulic cylinder can not accurately and stably stop in a certain position of the vehicle hydraulic cylinder, so it is one of the main indicators of the vehicle hydraulic cylinder.
How to control the speed of the cylinder?
High demand control, it is necessary to use servo closed-loop control, you can adjust the speed at will. Reference: Hydrodynamic Motion Control Practical Design Guide.
What is the principle of electric cylinder?
Principle: The electric cylinder converts the rotating motion of the motor into the linear motion of the push rod through the mechanical movement of the lead screw and the lead screw pair. With the closed-loop control characteristic of servo motor, the precise control of thrust, speed and position can be realized easily. Using modern motion control technology, numerical control technology and bus (network) technology, the program and bus (network) control is realized. Because of its easy control and use, it will realize the precision motion control that the cylinder and hydraulic cylinder drive can not achieve. Electric cylinder application field: 1, coordinate manipulator: logistics transmission, automated production line. 2. Wave making machine. 3, parallel mechanism: experimental platform, simulation platform, antenna. 4. Parallel machine tools. 5. Medical equipment: CT, Kamar
