Egypt hydraulic cylinder,roller press hydraulic cylinder manufacturer,roller press hydraulic cylinder(Egypt roller press hydraulic cylinder,produced by Hengyu Hydraulic Cylinder Factory)
roller press hydraulic cylinder are widely used in Egypt,because of long service life,smooth movement,high work efficiency.So our company has designed roller press hydraulic cylinder for customers from Egypt.
If it is found that the roller press hydraulic cylinder lubrication is poor or the roller press hydraulic cylinder bore processing is abnormal, it is necessary to feedback the situation to the manufacturer, because the piston and the roller press hydraulic cylinder, the guide rail and the piston rod have relative movement, if the lubrication is poor or the roller press hydraulic cylinder bore is abnormal, it will aggravate the wear and reduce the straightness of the roller press hydraulic cylinder center line. In this way, when the piston works in the roller press hydraulic cylinder, the friction resistance will be large and small, resulting in slip or crawling. The solution is to repair and grind the roller press hydraulic cylinder first, and then prepare the piston according to the matching requirements, repair and grind the piston rod, and configure the guide sleeve.
When the piston speed of the roller press hydraulic cylinder is high, the steel ball of the check valve flows with the oil flow, so that the valve hole is blocked, and the roller press hydraulic cylinder moves irregularly. Elimination method: Replace the steel ball with a cone valve or spool with a guide shoulder.
When the hydraulic oil is not pumped into the roller press hydraulic cylinder, it is necessary to check whether the tubing, oil circuit, especially the hose joint has been blocked, and the relevant oil circuit from the roller press hydraulic cylinder to the pump should be checked in turn and blocked; Check whether the seal between the taper valve and the seat of the relief valve is good; Check whether the solenoid valve spring is damaged or whether the solenoid coil is burned out; Whether the oil circuit is switched is insensitive.
The roller press hydraulic cylinder is not the same as the roller press hydraulic cylinder, because the pressure of the pneumatic system is generally within the range of 0.2-1.0Mpa, the roller press hydraulic cylinder can not be used as a high-power power component, but the roller press hydraulic cylinder can be used as a relatively large power component, or the roller press hydraulic cylinder system can be used.
How to judge the leakage in the cylinder?
Common judgment method: In the production site, people make full use of watching, listening, smelling, touching and other sensory ways, by observing that the cylinder can not move or delay the action or feel the oil temperature change, vibration and noise, etc., and then judge whether the cylinder has internal leakage according to experience. Another method commonly used in the field is to extend the cylinder in place to ensure that the cylinder does not have any load and will not retract (to prevent the cylinder from internal leakage accidents), turn off the machine, and then remove the tubing with the rod cavity, and then press the switch that pulls out the cylinder (do not press the wrong switch). If the oil nozzle with the rod cavity drains the cylinder internally, If there's no oil coming out, you have to think about something else going wrong.
Why are the hydraulic cylinders out of sync? The reasons for the unsynchronous operation are as follows: 1, the deviation of the external load of the two cylinders, such as the different resistance and friction of the two cylinders will lead to imbalance. The displacement of the cylinder with low resistance will be larger. 2, the difference in internal friction, such as the difference between the piston and the cylinder of each cylinder, the friction between the piston rod and the seal causes the cylinder to be out of sync. 3. The different resistance of hydraulic oil along the pipeline of the two cylinders causes the cylinder to be out of sync. 4, the deviation of the control original adjustment causes the deviation of the flow to be out of sync, such as the use of an independent throttle valve for each cylinder will appear the difference in the flow of oil in and out of the oil affecting the synchronization of the two cylinders. 5. The cylinder support point of the supported part is initially different.
