  Piston rod sealIt is widely used, because it has various advantages and characteristics, it is recognized by everyone, and it is easier to operate. Only in strict accordance with the operating regulations to use, in order to achieve good results, let's understand the use of piston rod seal matters needing attention.

The piston rod seal needs to be completely cleaned of various impurities in the cylinder and pipeline during use. When removing the seal from the warehouse, do not use the seal with sand, dust, etc., otherwise it will cause leakage. Of course, what you need to know when using is to coat a little hydraulic oil (the same as the oil of the machine itself) on the sealing gland, surface and cylinder surface, and then assemble it. Cylindrical. Add a cap to the sealing lip to prevent it from directly contacting the threads and steps. Or if necessary, put the lip directly through the oil pressure hole, and gently push the lip with a plastic round rod to prevent the chamfer of the hole from damaging the lip, and the cylinder must reverse the horn when drilling on it. Do not open the package unless it is necessary, otherwise dirt will adhere or scratch the seal. Store in a cool place away from direct sunlight. Ultraviolet rays and moisture accelerate the deterioration and dimensional changes of rubber and plastics. Or when storing the unpackaged piston rod seal, be careful not to adhere or wrap foreign matter, and store it in the original state. Nylon shall be tightly sealed to prevent dimensional changes due to moisture.

The piston rod seal must also ensure that the cylinder has a chamfer in use. If the cylinder does not have a chamfer, use a mounting sleeve. Deburring and chamfering or rounding the sharp edges and covering the threaded end of the screw. When the piston rod is sealed in use, of course, it is necessary to clean up debris, impurities... and other processing residues, and clean all parts. Or when the product is installed, you can apply oil or grease to the seal, which will make it easier to install. When installing rubber piston rod seals, attention must be paid to the compatibility of the sealing material with these lubricants. In order to obtain a good sealing effect during use, it is generally necessary to use a dust ring. If the oil film on the piston rod seal is thicker, the oil film ring remaining on the piston rod will be scraped off during movement, resulting in similar leakage, so this phenomenon must be prevented.
