This article mainly introduces:
The Philippines hydraulic cylinder,rolling mill cylinder manufacturer,rolling mill cylinder(The Philippines rolling mill cylinder,produced by Hengyu Hydraulic Cylinder Factory)
rolling mill cylinder are widely used in The Philippines,because of excellent fatigue and impact resistance,no need for deceleration device,long service life.So our company has designed rolling mill cylinder for customers from The Philippines.
When the rolling mill cylinder is disassembled due to oil leakage and other faults, the position of the piston should be moved to any end position of the rolling mill cylinder by applying liquid pressure. Improper tapping and sudden drop should be avoided during disassembly.
rolling mill cylinder buffer valve inspection and maintenance: For the valve buffer rolling mill cylinder, the focus should be on checking the wear of the buffer valve spool and seat. Once it is found that the amount of wear increases and the seal fails, it should be replaced. It can also be repaired by using abrasive spool and seat matching grinding method.
rolling mill 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 rolling mill cylinder seal and re-tighten the tie rod nut to reduce the pressure to the nominal pressure range of the rolling mill cylinder. c. The rolling mill cylinder seal is extruded, if the O-ring is obviously extruded at the rolling mill cylinder seal, replace the rolling mill cylinder seal.
When installing the rolling mill cylinder pipe, the pipe should be cleaned after installation, and should not pass through the rolling mill cylinder block, and the by-pass pipe must be installed in front of the oil port of the rolling mill cylinder block. This is important. Otherwise, the foreign body in the pipeline will enter the rolling mill cylinder, and once it enters, it is difficult to exclude it, but it becomes a foreign body transported to the rolling mill cylinder. Moreover, when cleaning, the removal method of foreign bodies entered in the installation pipeline operation should be considered. In addition, the corrosion in the pipe should be pickling and other procedures before the pipe installation, and the rust must be completely removed.
What adhesive should be used when the cylinder is cracked?
There is a kind of cast iron glue, industrial products market can buy, A, B formula, that is, a tube is A, a tube is B, when used proportionally prepared, check the instructions. Polish the glue after it dries, and then grind it again.
Why should the piston rod of the hydraulic cylinder be so precise? If you hope the cylinder has a long service cycle, then all parts need to be high-precision, not only the piston rod, but also the cylinder, the sealing groove, the surface roughness, the cylinder looks very simple. Any hydraulic factory can produce the cylinder, but the good cylinder is difficult to produce.
