Greece hydraulic cylinder,swager cylinder manufacturer,swager cylinder
(Greece swager cylinder,produced by Hengyu Hydraulic Cylinder Factory）
swager cylinder are widely used in Greece，because of high work efficiency，excellent fatigue and impact resistance，no need for deceleration device.So our company has designed swager cylinder for customers from Greece.
The piston rod and guide sleeve function of the swager cylinder is crucial: the relative motion pair between the piston rod and the guide sleeve is the main factor causing external leakage, if the chrome layer on the surface of the piston rod is spalling or producing longitudinal tensile marks due to wear, it will directly lead to the failure of the seal.
When the swager cylinder is installed, the piston and the swager cylinder head and other parts have large mass, large size and large inertia, even if there is a lifting equipment auxiliary installation, because the specified clearance is small, no matter how hard it will be put into, therefore, the end of the piston or the swager cylinder head boss is easy to cause scars when it hits the inner surface of the swager cylinder wall. The solution to this problem: for a large number of small products, the use of autocratic assembly oriented tools during installation; For heavy, thick and large large and medium-sized swager cylinders, only careful and careful operation can be avoided.
If it is found that the swager cylinder lubrication is poor or the swager cylinder bore processing is abnormal, it is necessary to feedback the situation to the manufacturer, because the piston and the swager cylinder, the guide rail and the piston rod have relative movement, if the lubrication is poor or the swager cylinder bore is abnormal, it will aggravate the wear and reduce the straightness of the swager cylinder center line. In this way, when the piston works in the swager cylinder, the friction resistance will be large and small, resulting in slip or crawling. The solution is to repair and grind the swager 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 swager cylinder is in use, ensure that the swager cylinder and the surrounding environment should be clean. The tank should be sealed to prevent contamination. Pipelines and fuel tanks should be cleaned to prevent falling off the oxide sheet and other debris. Clean with lint-free cloth or special paper. Twine and binder should not be used as sealing materials. Hydraulic oil according to the design requirements, pay attention to the change of oil temperature and oil pressure. When there is no load, unscrew the exhaust bolt for exhaust.
What are the cylinder manufacturing processes?
Hydraulic cylinder processing process: 1, cylinder: a, material preparation (seamless steel pipe) → inspection (material certificate, etc.) → tempering (outsourcing: Some parts) → car (car round, shelf mouth, boring, flange stop, etc.) → tempered hardness test → welding (welded pipe joint base, flange and other accessories) → boring or honing (rough boring, fine boring, rolling) → car (hole slot or internal and external thread) → fitter (drilling) → inspection → rust prevention storage b, material preparation (forgings) → inspection (material certificate, inspection, etc.) → welding (blank butt welding) → welding inspection → car (rough car) → quality control (outsourcing: some parts) → car (car round, shelf mouth, boring stop, flange stop, etc.)
What is the function of the Reza mounted master cylinder?
The role of the Resa-mounted master cylinder is to pump the concrete from the hopper to the delivery pipe and to provide sufficient concrete outlet pressure so that the concrete can reach the specified location.
