El Salvador hydraulic cylinder,punch machine hydraulic cylinder manufacturer,punch machine hydraulic cylinder(El Salvador punch machine hydraulic cylinder,produced by Hengyu Hydraulic Co., Ltd)
punch machine hydraulic cylinder are widely used in El Salvador,because of high work efficiency,excellent fatigue and impact resistance,no need for deceleration device.So our company has designed punch machine hydraulic cylinder for customers from El Salvador.
The punch machine hydraulic cylinder is mainly composed of body, piston, piston rod, punch machine hydraulic cylinder head, punch machine hydraulic cylinder bottom, piston rod head and related auxiliary devices. The piston divides the punch machine hydraulic cylinder into two chambers, and moves reciprocally in the punch machine 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 punch machine hydraulic cylinder head, due to the existence of the gap, it is easy to produce external leakage phenomenon, and the dust can enter the punch machine 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 punch machine 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 punch machine hydraulic cylinder bottom and the punch machine hydraulic cylinder head is serious, so the buffer deceleration should be set at both ends of the punch machine hydraulic cylinder The working medium of the punch machine hydraulic cylinder: because it works at room temperature, the ordinary oil-type hydraulic oil can be selected; punch machine 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 punch machine hydraulic cylinder: The buffer structure of the punch machine hydraulic cylinder is to prevent the piston from colliding with the punch machine hydraulic cylinder head at the end of the stroke.
punch machine hydraulic cylinder to reasonable use of hydraulic oil: strict hydraulic oil selection off. Hydraulic oil is selected in strict accordance with oil standards. The selection of good quality hydraulic oil can effectively prevent bubbles in the working process of the hydraulic system. When choosing the oil, it should be selected according to the lowest temperature in different regions, and fill the hydraulic oil according to the dipstick standard, and at the same time, it should also keep the hydraulic system clean (when filling the hydraulic oil, it should prevent the water and other impurities into it), and often check the oil quality, oil level and oil color of the hydraulic oil. If blisters and bubbles are found in the hydraulic oil. When the oil becomes milky white, the source of the air in the oil should be carefully found and eliminated in time.
When installing the punch machine hydraulic cylinder pipe, the pipe should be cleaned after installation, and should not pass through the punch machine hydraulic cylinder block, and the by-pass pipe must be installed in front of the oil port of the punch machine hydraulic cylinder block. This is important. Otherwise, the foreign body in the pipeline will enter the punch machine hydraulic cylinder, and once it enters, it is difficult to exclude it, but it becomes a foreign body transported to the punch machine hydraulic cylinder. Moreover, when cleaning, the removal method of foreign bodies entered in the installation pipeline operation should be considered. In addition, the corrosion in the pipe should be pickling and other procedures before the pipe installation, and the rust must be completely removed.
The body of the punch machine hydraulic cylinder on the processing process requirements: the body of the punch machine hydraulic cylinder is an important and essential part of the punch machine hydraulic cylinder, because it has an irreplaceable role. The processing requirements for this part are very high, requiring that the surface roughness of the punch machine hydraulic cylinder after processing should reach 0.4-0.8um, and the coaxiality and wear resistance requirements are also very high.
How to judge the failure of forklift hydraulic cylinder?
The common faults of the hydraulic cylinder of forklift truck are mainly crawling, insufficient thrust, working speed decline or even stop. Generally, crawling occurs at low speed. The main reason is that the air stored in the cylinder is not cleared. In addition, excessive or uneven mechanical friction can also cause crawling. Such as the piston and the piston rod different heart, the piston rod full length or local bending, the cylinder hole straightness is poor, the cylinder is drum shaped or has a large taper, the cylinder thin finish decline or produce hair, the cylinder installation accuracy is out of whack, the piston rod nuts at both ends of the screw too tight to make its concentricity is poor, the oil seal screw too tight friction is too large, will cause crawling.
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.
