Sri Lanka hydraulic cylinder,baling press cylinder manufacturer,baling press cylinder(Sri Lanka baling press cylinder,produced by Hengyu Group)
baling press cylinder are widely used in Sri Lanka,because of no transmission clearance,powerful torque,clever hydraulic energy conversion.So our company has designed baling press cylinder for customers from Sri Lanka.
If it is found that the baling press cylinder lubrication is poor or the baling press cylinder bore processing is abnormal, it is necessary to feedback the situation to the manufacturer, because the piston and the baling press cylinder, the guide rail and the piston rod have relative movement, if the lubrication is poor or the baling press cylinder bore is abnormal, it will aggravate the wear and reduce the straightness of the baling press cylinder center line. In this way, when the piston works in the baling press cylinder, the friction resistance will be large and small, resulting in slip or crawling. The solution is to repair and grind the baling press cylinder first, and then prepare the piston according to the matching requirements, repair and grind the piston rod, and configure the guide sleeve.
When producing oil baling press cylinders, there are two processing processes, grinding and rolling, the latter is better than the former. Rolling machining is a kind of non-cutting machining, using the plastic deformation of the metal at room temperature, so that the micro roughness of the workpiece surface is flattened to achieve the purpose of changing the surface structure, mechanical characteristics, shape and size. Therefore, this method can achieve the two purposes of finishing and strengthening at the same time, which can not be done by grinding.
The daily inspection of the baling press cylinder includes: checking the connection of the baling press cylinder and the pipe joint for leaks. Check the baling press cylinder rod for leaks. Check the baling press cylinder connection for leaks. When the baling press cylinder moves, the work is normal and smooth. Whether the baling press cylinder has internal leakage.
The coordination of the sliding parts of the baling press cylinder itself should not be too tight, the sealing friction force should not be too large, and H8 / f8 coordination should be selected between the piston rod and the guide sleeve; Check whether the size of the sealing ring is processed strictly according to the standard; If the V-shaped sealing ring is used, the sealing friction should be adjusted to a moderate degree.
What is the problem that the cylinder stroke is not in place?
1. Mechanical cause: the piston rod bends; If there is a synchronous cylinder, the stroke of the two cylinders may be different. 2. Hydraulic reason: the system back pressure is too large; The actuator load increases while the system pressure decreases. The electric is not sent, the reversing valve is not reset or stuck, the oil is too dirty, there is gas in the system, the external inertia load is too large, and the cylinder stroke is not in place.
What is the rated pressure of the general cylinder?
This depends on the model of the cylinder, 1. The rated pressure of the light tie rod cylinder is 7 series 7MPa and 14 series 14MPa. 2. Rated pressure of engineering cylinder 16MPa. 3. Rexroth type metallurgical cylinder rated pressure 250MPa.
