Saudi Arabia hydraulic cylinder,steel mill cylinder manufacturer,steel mill cylinder(Saudi Arabia steel mill cylinder,produced by Hebei Hengyu company)
steel mill cylinder are widely used in Saudi Arabia,because of excellent temperature resistance,no transmission clearance,powerful torque.So our company has designed steel mill cylinder for customers from Saudi Arabia.
When the control pressure of the hydraulic system is too low, the steel mill 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.
When the steel mill cylinder is in use, measures should be added to prevent the intrusion of pollutants. Effective measures should be taken to control the intrusion of pollutants, such as installing high-efficiency air filters in the tank breathing holes, new oil must be filtered, etc., but also must improve the anti-pollution ability of the steel mill cylinder itself. In the seriously polluted environment, it is more important to pay attention to, such as the underground oil steel mill cylinder should use fluorine rubber (FRM) and nitrile rubber (NBR) dust ring, and the ground mechanical steel mill cylinder should use nitrile rubber dust ring; The filter device is added to the oil inlet of the steel mill cylinder of the dump truck, construction machinery, work platform and other equipment, and in order to reduce the oil inlet resistance, the flow area should be increased as much as possible, which can effectively reduce the particle pollution from the system.
If the seal of the steel mill cylinder is abnormal wear, you can check whether the speed control valve is improperly adjusted, resulting in too high back pressure and improper installation of the seal or hydraulic oil contamination. The second is whether there is a foreign body entering the assembly and the quality of the sealing material is not good. The result is that the action is slow and weak, and in serious cases, it will cause damage to the piston and steel mill cylinder, and the phenomenon of "pulling the steel mill cylinder" appears. The treatment method is to adjust the speed control valve, and the necessary operation and improvement should be done according to the installation instructions.
Classification of steel mill cylinder: according to the mode of movement it can be divided into linear reciprocating movement type and rotary swing type; According to the effect of liquid pressure, it can be divided into single acting type and double acting type. According to the structure, it can be divided into piston type, plunger type, multistage telescopic sleeve type, pinion and rack type, etc. According to the installation form can be divided into rod, earring, foot, hinge shaft and so on; According to the pressure grade can be divided into 16Mpa, 25Mpa, 31.5Mpa and so on.
How does the hydraulic solenoid valve realize that the cylinder stops at any position?
Use an O-type medium function solenoid directional valve, or use a Y-type solenoid directional valve and a hydraulically controlled check valve.
Why does the hydraulic cylinder not return?
For a spring return cylinder, it is possible that 1, the spring is damaged. You can check it for processing. 2, the oil in the oil path is not unloaded, causing it to be unable to reset. 3, the cylinder piston is dead, resulting in no position. For double-acting cylinders, it is possible to: 1, the spool is not reversed, or is not changed to the correct position, check whether the reversing valve is normal (and whether there is electricity). 2, the cylinder piston is dead, resulting in no position, check and treatment can be. 3, the return oil pressure is insufficient, the inlet oil is not unloaded, the operation is not smooth.
