Chile hydraulic cylinder,stacker cylinder manufacturer,stacker cylinder
(Chile stacker cylinder,produced by Hebei Hengyu company）
stacker cylinder are widely used in Chile，because of powerful torque，clever hydraulic energy conversion，simple structure and reliable operation.So our company has designed stacker cylinder for customers from Chile.
stacker cylinder spool stuck or valve hole blocked How to solve: When the flow valve or direction valve spool stuck or valve hole blocked, the stacker cylinder prone to misoperation or action failure. At this time, the contamination of the oil should be checked; Check whether dirt or colloidal deposits are stuck in the spool or blocking the valve hole; Check the wear of the valve body, clean and replace the system filter, clean the fuel tank, and replace the hydraulic medium.
stacker cylinder diameter, rod diameter, stroke determination: Choose national standards or other standards stacker cylinder, avoid the selection of non-standard size, otherwise the difficulty of processing and manufacturing costs will be increased. The length of the stacker cylinder guide is determined by the length of the stroke. Check the strength of stacker cylinder, piston rod, screw, etc. according to the working pressure or load. At the same time, working pressure, ambient temperature, working medium and running speed are also the key to selecting seals.
If it is found that the stacker cylinder lubrication is poor or the stacker cylinder bore processing is abnormal, it is necessary to feedback the situation to the manufacturer, because the piston and the stacker cylinder, the guide rail and the piston rod have relative movement, if the lubrication is poor or the stacker cylinder bore is abnormal, it will aggravate the wear and reduce the straightness of the stacker cylinder center line. In this way, when the piston works in the stacker cylinder, the friction resistance will be large and small, resulting in slip or crawling. The solution is to repair and grind the stacker cylinder first, and then prepare the piston according to the matching requirements, repair and grind the piston rod, and configure the guide sleeve.
The quality of the stacker cylinder can not be ignored in the purchase of the stacker cylinder. The stacker cylinder is the main component of the stacker cylinder, the single pillar for mining, the hydraulic support, the gun tube and other products, and its processing quality directly affects the life and reliability of the entire product. stacker cylinder processing requirements are high, its internal surface roughness requirements are Ra0.4 ~ 0.8μm, the coaxiality, wear resistance requirements are strict. The basic feature of stacker cylinder is deep hole processing, which has always troubled the processing personnel.
What is hydraulic cylinder internal leakage and external leakage?
The internal leakage of the hydraulic cylinder refers to the leakage of the piston head seal of the double-acting cylinder, and the leakage occurs inside the cylinder; The external leakage refers to the leakage phenomenon between the cylinder head (or cylinder guide sleeve) and the plunger rod (or piston rod) and the seal between the guide sleeve and the cylinder block, and the oil in the hydraulic cylinder leaks to the outside.
Why the cylinder cannot operate normally after the explosion-proof valve is installed?
The pipeline explosion-proof valve is specially designed to prevent pipeline damage and free fall of the cylinder, so there must be back pressure to open. If there is no oil return pressure, or the oil return pressure is too small, and can not adjust the oil return pressure, such a system with explosion-proof valves is more troublesome, it is recommended to add a one-way throttle valve between the cylinder and the tank to establish back pressure. If you understand the explosion-proof valve, you can also try to adjust the opening of the valve (that is, the flow of the regulating valve), and adjust the opening to help the valve to open.
