Poland hydraulic cylinder,shearing machine cylinder manufacturer,shearing machine cylinder(Poland shearing machine cylinder,produced by Hengyu Hydraulic Cylinder Factory)
shearing machine cylinder are widely used in Poland,because of no need for deceleration device,long service life,smooth movement.So our company has designed shearing machine cylinder for customers from Poland.
When the control pressure of the hydraulic system is too low, the shearing machine cylinder will appear wrong or no action, because the throttle resistance in the control pipeline may be too large, the flow valve is improperly adjusted, the control pressure is inappropriate, and the pressure source is interfered with. At this time, check the control pressure source to ensure that the pressure is adjusted to the specified value of the system.
shearing machine cylinder installation precautions: Before installing the shearing machine cylinder into the system, the parameters on the shearing machine cylinder label should be compared with the parameters when ordering. The base of the shearing machine cylinder must have sufficient stiffness, otherwise the shearing machine cylinder will bend upward into a bow when pressurized, so that the piston rod will bend.
shearing machine cylinder buffer valve inspection and maintenance: For the valve buffer shearing machine cylinder, the focus should be on checking the wear of the buffer valve spool and seat. Once it is found that the amount of wear increases and the seal fails, it should be replaced. It can also be repaired by using abrasive spool and seat matching grinding method.
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 shearing machine 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.
Is there a national standard for the testing of hydraulic cylinders?
Generally speaking, the cylinder test is carried out according to JB/JQ20302 Allowable leakage of cylinder in pre-factory leakage test. GB2879 hydraulic cylinder piston and piston rod dynamic seal groove type, size and tolerance. GB6578 hydraulic cylinder piston rod dust ring groove type, size and tolerance. GB7938 hydraulic cylinder and cylinder nominal pressure series, etc.
What is hydraulic cylinder? How to use hydraulic cylinder? what is the application of hydraulic cylinder?
Hydraulic cylinder is the hydraulic actuator that converts hydraulic energy into mechanical energy and does linear reciprocating movement (or swing movement). 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 hydraulic cylinder is proportional to the effective area of the piston and the pressure difference between the two sides. The hydraulic cylinder is basically composed of cylinder body, cylinder head, piston, piston rod, sealing device, buffer device and exhaust device. Buffer device and exhaust device depending on the specific application, other devices are essential. Hydraulic cylinders are mainly used in machinery.
