Uganda hydraulic cylinder,stroke adjustable cylinder manufacturer,stroke adjustable cylinder(Uganda stroke adjustable cylinder,produced by Hengyu Hydraulic Cylinder Factory)
stroke adjustable cylinder are widely used in Uganda,because of clever hydraulic energy conversion,excellent temperature resistance,simple structure and reliable operation.So our company has designed stroke adjustable cylinder for customers from Uganda.
When the stroke adjustable cylinder is in use, once the seal and guide support ring are found to be defective, the seal with the same structural form and appropriate material should be replaced according to the structural form of the stroke adjustable cylinder seal to be repaired, so as to minimize the thickness of the oil film between the seal and the sealing surface and reduce the leakage of the seal.
stroke adjustable cylinder diameter, rod diameter, stroke determination: Choose national standards or other standards stroke adjustable cylinder, avoid the selection of non-standard size, otherwise the difficulty of processing and manufacturing costs will be increased. The length of the stroke adjustable cylinder guide is determined by the length of the stroke. Check the strength of stroke adjustable 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.
When the stroke adjustable cylinder is kept, do not pay attention to keeping the oil port open, which will produce the condition of accepting foreign bodies at all times, which is absolutely not allowed. Storage must be filled with anti-rust oil or working oil, and plug.
Causes and countermeasures of oil stroke adjustable cylinder leakage: Cast iron ring seal allows a certain degree of internal leakage. The impurities in the stroke adjustable cylinder will lead to premature wear of the piston seal, replace the piston seal; If the stroke adjustable cylinder is visibly scarred, the stroke adjustable cylinder must be replaced. It can be pressurized at one end of the stroke adjustable cylinder and opened at the other end of the oil port to observe whether there is obvious internal leakage at the end of the oil port. Most stroke adjustable cylinder piston drift may not come from the stroke adjustable cylinder, the above method to determine the stroke adjustable cylinder without internal leakage is helpful to determine the problem of the hydraulic system related components.
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.
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.
