Guatemala hydraulic cylinder,stroke adjustable cylinder manufacturer,stroke adjustable cylinder(Guatemala stroke adjustable cylinder,produced by Hengyu Group)
stroke adjustable cylinder are widely used in Guatemala,because of excellent temperature resistance,no transmission clearance,powerful torque.So our company has designed stroke adjustable cylinder for customers from Guatemala.
The viscosity of the working oil used in the stroke adjustable cylinder is 29~74mm2/S, and ISO VG46 anti-wear hydraulic oil is recommended. Working oil temperature within the range of -20~80. C. When the ambient temperature and service temperature are low, the oil with lower viscosity can be selected.
The stroke adjustable cylinder should be used correctly and maintained regularly. The stroke adjustable cylinder should be deflated before use, the buffer regulating valve should be adjusted to a reasonable position, the cleanliness of the oil should be checked regularly, the dust on the stroke adjustable cylinder should be cleaned regularly, and attention should be paid to waterproof and fireproof.
When producing oil stroke adjustable 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 stroke adjustable cylinder is mainly composed of body, piston, piston rod, stroke adjustable cylinder head, stroke adjustable cylinder bottom, piston rod head and related auxiliary devices. The piston divides the stroke adjustable cylinder into two chambers, and moves reciprocally in the stroke adjustable 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 stroke adjustable cylinder head, due to the existence of the gap, it is easy to produce external leakage phenomenon, and the dust can enter the stroke adjustable 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 stroke adjustable 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 stroke adjustable cylinder bottom and the stroke adjustable cylinder head is serious, so the buffer deceleration should be set at both ends of the stroke adjustable cylinder The working medium of the stroke adjustable cylinder: because it works at room temperature, the ordinary oil-type hydraulic oil can be selected; stroke adjustable 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 stroke adjustable cylinder: The buffer structure of the stroke adjustable cylinder is to prevent the piston from colliding with the stroke adjustable cylinder head at the end of the stroke.
Cylinder la-50-70st What does that mean?
Full model should be CX-LA-50-70ST, thin block cylinder, radial mounting, bore 50, stroke 70.
PLC+ inverter + motor + pump + solenoid valve + cylinder combination, can control the accuracy of cylinder position?
In the case of extremely high accuracy requirements, you can not, please consider a few problems: 1, hydraulic oil can be compressed, it is elastic like a spring. Therefore, in the general hydraulic servo system, the valve control is far more accurate than the pump control. Because the valve can be installed very close to the hydraulic cylinder, or even installed on the hydraulic cylinder, but the pump must go through the tubing and then into the hydraulic cylinder, there is a long distance, which greatly reduces the rigidity of the system and increases the difficulty of control. 2, the quantitative pump is first of all leaking, and there is 10%-20% flow pulsation. Secondly, and more unfortunately, the leakage of the pump is related to the pressure and is non-linear.
