Oman hydraulic cylinder,hydraulic punch cylinder manufacturer,hydraulic punch cylinder(Oman hydraulic punch cylinder,produced by Hengyu Group)
hydraulic punch cylinder are widely used in Oman,because of clever hydraulic energy conversion,simple structure and reliable operation,excellent temperature resistance.So our company has designed hydraulic punch cylinder for customers from Oman.
The wear of the hard chromium plating layer of the hydraulic punch cylinder is mostly caused by the grinding of the friction iron powder of the piston, and the wear is faster when there is water in the middle. Corrosion caused by the contact potential difference of the metal only occurs in the part of the piston contact, and the corrosion occurs in a point pattern. As mentioned above, when there is moisture in the middle, it will promote the development of corrosion. Compared with castings, the contact potential difference of copper alloy is higher, so the corrosion degree of copper alloy is more serious.
Regular maintenance of the hydraulic punch cylinder includes: regular tightening, hydraulic punch cylinder fastening screws and gland screws, hydraulic punch cylinder piston rod stop adjustment screws, should be tightened once a month, tighten each screw evenly, and achieve the corresponding tightening torque. Replace the seal regularly, it is recommended to replace the seal of the hydraulic punch cylinder once a year. Clean regularly, the hydraulic punch cylinder is cleaned every other year, and the seals are replaced while cleaning.
hydraulic punch cylinder seal leakage causes and countermeasures: a. Loose tie rod nut will cause leakage, tighten the tie rod nut according to the torque requirements of tie rod nut, test no leakage can continue to use. b. Pressure exceeding the limit will also cause leakage. Replace the hydraulic punch cylinder seal and re-tighten the tie rod nut to reduce the pressure to the nominal pressure range of the hydraulic punch cylinder. c. The hydraulic punch cylinder seal is extruded, if the O-ring is obviously extruded at the hydraulic punch cylinder seal, replace the hydraulic punch cylinder seal.
hydraulic punch cylinder can not drive the load troubleshooting: oil pressure is too low. hydraulic punch cylinder selection specifications are too small. Leakage in hydraulic punch cylinder or associated hydraulic system element.
What is the bearing capacity of the HOB cylinder?
The normal specification of HOB is 140 kg pressure, which is more commonly used in the market, and there are clear marks on the cylinder, 210 kg is a strengthened version of HOB, generally customized cylinders are also clearly marked on the above, when the specific use of the cylinder, the maximum use pressure is marked on the cylinder.
Why does the cylinder pop out of itself when it stops?
This situation has two possibilities, 1. There is more air in the system, so exhaust the gas. 2. The back pressure of the oil return is relatively large, check the oil return filter, check whether the cylinder has a rod cavity buffer is too tight, and choose a 3-position 4-way M-type valve for the reversing valve. In addition, after the shutdown, manually change the reversing valve back and forth several times, it should not rise out.
