Hungary hydraulic cylinder,stacker cylinder manufacturer,stacker cylinder(Hungary stacker cylinder,produced by Hengyu Hydraulic Cylinder Factory)
stacker cylinder are widely used in Hungary,because of excellent fatigue and impact resistance,excellent temperature resistance,simple structure and reliable operation.So our company has designed stacker cylinder for customers from Hungary.
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.
The stacker cylinder should be avoided for a long time without use, if it is indeed idle for a long time for some reason, it should also be regularly turned on for empty operation, so that its parts can be fully lubricated, so as to avoid rust on the working surface and affect the normal work in the future. (If it cannot be turned on and run, a small amount of lubricating oil can be applied on its outer surface for protection) ' The use of the stacker cylinder should pay attention to: the operation should be as far away from the stacker cylinder as possible, to avoid falling objects, knocking, rubbing the stacker cylinder coating. When cleaning the stacker cylinder, only use soft materials (such as cotton) to wipe, and do not scratch high-hardness materials. Do not use the stacker cylinder when the oil temperature exceeds 70 ° C.
The meaning of the stacker cylinder model marked by the stacker cylinder manufacturer: for example, 160/100-1150, its meaning: from a professional point of view, 160 refers to the stacker cylinder diameter, which is 160mm, and the 100 behind refers to the rod diameter, which is 100mm. The 1150 refers to the stacker cylinder stroke, which is 1150mm. Therefore, on this point, we should have a correct understanding and can not make mistakes.
When the stacker cylinder thrust is insufficient, check the hydraulic circuit for leaks. Including leakage of valves and hydraulic lines. The inspection method is to check and eliminate the leakage of the hydraulic connection line by manipulating the reversing valve. Also consider the relief valve. If the relief valve enters the dirt and jams the spool, so that the relief valve is normally open, the hydraulic oil will flow directly back to the tank through the relief valve bypass, resulting in no oil in the stacker cylinder. If the load is too large, although the regulating pressure of the relief valve has reached the maximum rating, the stacker cylinder still cannot get the thrust required for continuous action without action. If the regulating pressure is low, the pressure is insufficient to achieve the required vertebra force, which is manifested as insufficient thrust. Check and adjust the relief valve at this time.
How to deal with the surface degreasing process before spraying paint after cylinder assembly, and what degreasing agent is used?
Cylinder painting, generally using the following process (note: the cylinder is best painted, do not spray powder coating, because the powder coating curing temperature is high, will lead to sealing defects and oil leakage) : Pre-degreasing - degreasing - washing - washing - pickling - washing - washing - table adjustment - phosphating - washing - washing - drying - polishing - spray primer - spray paint degreasing agent generally use neutral or weak alkaline degreasing agent, phosphating liquid generally use zinc phosphating liquid.
How big is the 100t cylinder pump and how big is the motor?
Load is calculated at 15 tons, stroke is calculated at 100 (both take the maximum) 15 tons = 15,000 kg, 15,000/210 bar (21 mpa) =71.42 square centimeters (cylinder area) 71.42/3,14 In the root *2=90,5 the inner diameter of the cylinder can be taken 100 mm. Travel 100 cm, that is, one meter, assuming 10, seconds a back and forth, then it is six times a minute, six meters per minute, then the required flow is,71,42*600 cm (6 meters) =42840 mm =42.84 liters/minute 42.84*21/60=14.9 kilowatts can choose 1450 RPM 4-stage motor 15KW.
