Bahrain hydraulic cylinder,synchronous hydraulic cylinder manufacturer,synchronous hydraulic cylinder(Bahrain synchronous hydraulic cylinder,produced by Hengyu Hydraulic Cylinder Factory)
synchronous hydraulic cylinder are widely used in Bahrain,because of high work efficiency,long service life,smooth movement.So our company has designed synchronous hydraulic cylinder for customers from Bahrain.
When the initial action of the synchronous hydraulic cylinder is slow, please check the temperature of the hydraulic system, because in the case of low temperature, the viscosity of the hydraulic oil is large and the fluidity is poor, resulting in slow action of the synchronous hydraulic cylinder. The improvement method is to replace the hydraulic oil with good viscosity temperature performance, and the oil temperature at low temperature can be increased by heater or heating by the machine itself, and the normal working oil temperature of the system should be maintained at about 40 ° C.
synchronous hydraulic cylinder installation precautions: Before installing the synchronous hydraulic cylinder into the system, the parameters on the synchronous hydraulic cylinder label should be compared with the parameters when ordering. The base of the synchronous hydraulic cylinder must have sufficient stiffness, otherwise the synchronous hydraulic cylinder will bend upward into a bow when pressurized, so that the piston rod will bend.
When the synchronous hydraulic cylinder is installed on the main engine, the oil port piping part and the guide sleeve should be checked for oil leakage in the running test, and the earring and the middle hinge shaft bearing should be refueled.
Before the synchronous hydraulic cylinder is removed, the relief valve should be loosened to reduce the pressure of the hydraulic circuit to zero, and then the power supply should be cut off to stop the hydraulic device. After loosening the oil port piping, the oil plug should be applied to plug the oil port.
How long can a hydraulic cylinder work continuously?
If the maintenance is good, the service life can be extended a lot. The life of the cylinder is related to the structure of the cylinder, working pressure, stress state, hydraulic oil cleanliness, oil temperature control, maintenance and preventive measures. For example, the cylinder structure, the inner wall of the cylinder has quilting, rolling, chrome plating and other methods, the sealing parts have polyurethane rings, glay rings, metal sealing rings, etc., different combinations, the life difference is dozens of times. Metallurgical system is a typical cylinder application, in 24 hours of work, a year or more can not be shut down, in the middle of continuous work.
What are the causes of hydraulic cylinder oil leakage?
First, between the piston rod and the guide sleeve: 1, the cylinder force is not good, there is a radial force between the piston rod and the guide sleeve there is a partial load, so that the oil seal is worn early, causing oil leakage. 2. The ambient temperature of the piston rod is high, especially radiant heat, and the oil seal aging is fast. 3. Whether the oil seal is selected correctly; Check whether the oil seal is damaged during installation. 4, guide sleeve and piston rod matching tolerance is correct. Second, between guide sleeve and cylinder: 1. Whether the O-ring on the guide sleeve is installed correctly, pay special attention to the O-ring can not "roll", especially some O-rings are die-pressed with a die-closing line. Third, common problems: 1, guide sleeve, cylinder, piston rod concentricity is poor. Fit tolerance is correct.
