Luxembourg hydraulic cylinder,stern plate hydraulic cylinder manufacturer,stern plate hydraulic cylinder(Luxembourg stern plate hydraulic cylinder,produced by Hebei Hengyu company)
stern plate hydraulic cylinder are widely used in Luxembourg,because of clever hydraulic energy conversion,simple structure and reliable operation,excellent temperature resistance.So our company has designed stern plate hydraulic cylinder for customers from Luxembourg.
The piston seal of the stern plate hydraulic cylinder is the main element to prevent leakage in the stern plate hydraulic cylinder. For the lip seal, it should focus on checking whether the lip edge is bruised and worn, and for the combination seal, it should focus on checking the wear of the sealing surface, and then determine whether the seal can be used. In addition, it is necessary to check whether the static seal between the piston and the piston rod is crushed. The piston rod seal should focus on checking the wear of the seals and supporting rings.
When the stern plate hydraulic cylinder wear is serious, you can try to use an alloy scraper to shave grooves with a depth of more than 1mm on the surface of the slip injury, then clean the grooves with acetone, apply the adjusted TS311 anti-wear repair agent on the polished surface with the stern plate hydraulic cylinder inner diameter copying plate, and scrape it flat vigorously to ensure compaction and higher than the inner surface of the stern plate hydraulic cylinder. After curing, polish to leave a finishing margin. Finally, the overall size, shape tolerance and roughness of the stern plate hydraulic cylinder can meet the requirements by grinding. However, the life and reliability of this repair stern plate hydraulic cylinder are not high.
How to determine the working pressure of the stern plate hydraulic cylinder: The pressure depends on the load size (i.e., F) and the type of equipment. The limitations of assembly space, economic conditions and component availability of the actuator should also be considered. In the case of a certain load, it is necessary to increase the structural size of the actuator if the working pressure is low, for some equipment, the size may be limited, and it is not economical from the point of view of material consumption; On the contrary, if the pressure selection is too high, the material, sealing and manufacturing accuracy of the pump, stern plate hydraulic cylinder, valve and other components are also required to be high, which will inevitably increase the cost of equipment. In general, for equipment with a fixed size that is not too limited, the pressure can be selected lower, and the walking machinery should be selected higher.
The stern plate hydraulic cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and does linear reciprocating motion (or swinging motion). It is simple in structure and reliable in operation. When it is used to achieve reciprocating movement, the deceleration device can be eliminated, and there is no transmission gap, and the movement is smooth, so it is widely used in various mechanical hydraulic systems. The output force of the stern plate hydraulic cylinder is proportional to the effective area of the piston and the pressure difference between the two sides; The stern plate hydraulic cylinder is basically composed of stern plate hydraulic cylinder and stern plate hydraulic cylinder head, piston and piston rod, sealing device, buffer device and exhaust device. Buffer device and exhaust device depending on the specific application, other devices are essential.
How to disassemble injection molding machine injection cylinder?
If it is not repaired for a long time, it is recommended to open both ends, comprehensively check the oil seal and piston ring inside, this is not much difficulty, pay attention to not install reverse when changing the oil seal, some piston rings are steel rings are rubber rings, and several interfaces of steel rings are not in the same position; Rubber ring pay attention not to install reverse; Be careful not to damage the oil seal when installing, otherwise it will soon leak oil.
Hydraulic cylinder cost calculation method
1, Price cost accounting. Hydraulic cylinder price is composed of cost, profit and tax rate. Among them, the cost includes material cost, processing cost, assembly test fee, factory management fee (including the cost of designing drawings, etc., and the salary of management personnel is shared equally), brand promotion fee, utility and electricity equipment depreciation fee and other expenses. Cost of materials, including cylinder composition cylinder, piston rod, front and rear cover, guide, piston, seal, other accessories, etc. 2, Roughly estimate cylinder price = cylinder weight * parameters, parameters comprehensive consideration of various material costs and processing fees. The general market parameter is 20, the smaller and lighter the cylinder, the larger and heavier the cylinder, the smaller the parameter.
