Kuwait hydraulic cylinder,heat press hydraulic cylinder manufacturer,heat press hydraulic cylinder(Kuwait heat press hydraulic cylinder,produced by Hebei Hengyu company)
heat press hydraulic cylinder are widely used in Kuwait,because of powerful torque,clever hydraulic energy conversion,simple structure and reliable operation.So our company has designed heat press hydraulic cylinder for customers from Kuwait.
Causes and countermeasures of oil heat press hydraulic cylinder leakage: Cast iron ring seal allows a certain degree of internal leakage. The impurities in the heat press hydraulic cylinder will lead to premature wear of the piston seal, replace the piston seal; If the heat press hydraulic cylinder is visibly scarred, the heat press hydraulic cylinder must be replaced. It can be pressurized at one end of the heat press hydraulic cylinder and opened at the other end of the oil port to observe whether there is obvious internal leakage at the end of the oil port. Most heat press hydraulic cylinder piston drift may not come from the heat press hydraulic cylinder, the above method to determine the heat press hydraulic cylinder without internal leakage is helpful to determine the problem of the hydraulic system related components.
Regular maintenance of the heat press hydraulic cylinder includes: regular tightening, heat press hydraulic cylinder fastening screws and gland screws, heat press hydraulic cylinder piston rod stop adjustment screws, should be tightened once a month, tighten each screw evenly, and achieve the corresponding tightening torque. Replace the seal regularly, it is recommended to replace the seal of the heat press hydraulic cylinder once a year. Clean regularly, the heat press hydraulic cylinder is cleaned every other year, and the seals are replaced while cleaning.
The pressure, temperature, medium and speed of different types of seals are not the same, water-ethylene glycol medium (HFC) can not be sealed with polyurethane, it can only use rubber seal; When the heat press hydraulic cylinder is running fast, it must be sealed with slip ring, such as Sterseal, Glairing, GD1000K, TDI, etc., when the running speed is slow, Yx, U, V combination seals can be used; Fluorine rubber seal is used in high temperature and high pressure environment; When the running speed is fast, the buffer sleeve and buffer valve must be considered.
When the heat press hydraulic cylinder needs to be stored for a period of time, please follow the recommended methods: The heat press hydraulic cylinder should be stored in a dry, clean, non-corrosive gas indoor environment, pay attention to protect the heat press hydraulic cylinder from internal corrosion and external damage. If the indoor requirements cannot be met, the hardened and well-drained ground should be cushioned at least 30cm, and the upper part should be covered with waterproof storage. The oil heat press hydraulic cylinder should not be in direct contact with water vapor for a long time. The heat press hydraulic cylinder should be placed as vertically as possible with the piston rod facing up, which minimizes corrosion due to possible condensation in the heat press hydraulic cylinder and permanent deformation of the seal due to the piston and rod weight. (When the shield is stored in the shield machine, the support shoe is placed upward). Keep the oil port protective cover until the pipe is connected. For long-term storage, the protection should be added on both sides of the piston of the heat press hydraulic cylinder Before working, the heat press hydraulic cylinder must be run repeatedly with low pressure (greater than the starting pressure) to discharge the air in the heat press hydraulic cylinder before normal work. The oil inlet and outlet and the joint must be tightly fastened with a combination pad to prevent oil leakage.
Why can't the hydraulic cylinder be pulled back after pushing to the limit?
May be long-term use to the limit position, resulting in serious wear caused! The solution is to add the stroke switch or disassemble and add gaskets before and after the piston.
Can the hydraulic oil in the cylinder return to the tank?
Yes, there is a way, for example, first remove the cylinder from the machine, and then connect the two pipes on the cylinder, so that the cylinder piston rod is completely retracted into the cylinder, at this time, the piston is with the bottom, and the rear chamber is almost no oil, and then screw off the joint at the end of the front chamber by the hydraulic station, and put it in an empty bucket. Finally, insert the gas pipe into the oil port of the rear chamber. Open the air source, and then the rod will run out, and you'll drain the hydraulic oil from the end of the rod, which requires a source of air on site.
