Germany hydraulic cylinder,stern plate hydraulic cylinder manufacturer,stern plate hydraulic cylinder(Germany stern plate hydraulic cylinder,produced by Hebei Hengyu company)
stern plate hydraulic cylinder are widely used in Germany,because of simple structure and reliable operation,excellent temperature resistance,no transmission clearance.So our company has designed stern plate hydraulic cylinder for customers from Germany.
stern plate hydraulic cylinder use should try to avoid sealing belt into the stern plate hydraulic cylinder. As a simple sealing material, polytetrafluoroethylene plastic sealing tape is often used in installation and inspection, and if the winding method of the linear and ribbon-shaped sealing material is wrong, the sealing tape will be cut off and enter the stern plate hydraulic cylinder. The wire belt seal will not have any effect on the winding of the sliding part, but it will cause the check valve of the stern plate hydraulic cylinder to fail to operate or the buffer regulating valve can not be adjusted to the end. For the circuit, it may cause the action of the reversing valve, the relief valve and the reducing valve to fail.
In order to ensure the service life of the stern plate hydraulic cylinder, the hydraulic system must be set up effective filtration to prevent pollution, the cleanliness of the oil should meet the ISO4406 standard, and the quality of the filtration should also meet the corresponding standards in ISO. The grade requirements of the filter are performed according to the actual working conditions of the system, but the minimum requirements are not less than 19/15 in ISO4406, that is, 24μ (β10≥75) in ISO4572.
The stern plate hydraulic cylinder requires that the filtration accuracy of the system is not less than the 80um, and the oil pollution should be strictly controlled, the oil should be kept clean, the performance of the oil should be checked regularly, and the necessary fine filtration and replacement of new working oil should be carried out.
The coordination of the sliding parts of the stern plate hydraulic cylinder itself should not be too tight, the sealing friction force should not be too large, and H8 / f8 coordination should be selected between the piston rod and the guide sleeve; Check whether the size of the sealing ring is processed strictly according to the standard; If the V-shaped sealing ring is used, the sealing friction should be adjusted to a moderate degree.
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
When the cylinder is tested, why can't the pressure be maintained with the balance valve?
Because the oil into the oil chamber through the hydraulic lock on the control oil circuit through the other side of the spool, the original valve is designed in this way. It locks the circuit after the oil supply circuit loses pressure, on the contrary, if you keep supplying pressure, it is always in the state of opening the other side of the one-way spool. So this valve can't be used in the test.
