Cautions when installing the piston rod
The piston rod is a connection often applied to almost all mechanical equipment, so we must pay attention to its installation. Otherwise, if the installation is not correct, it may cause the device to fail to operate normally. So, let's share today what specific issues should be paid attention to when installing the piston rod of the equipment.
In order to facilitate everyone's understanding, the following aspects of the equipment installation piston rod to pay attention to are summarized as follows:
1. In order to effectively improve the assembly quality of the equipment so as to work better. Before installing the piston rod, ensure that the clearance between the piston and the cylinder meets the requirements. And check whether the tolerances of the cylinder liner are qualified.
2. After the inspection is completed, if an abnormality is found, a new sealing rubber ring needs to be installed next. At this time, the piston rod manufacturer must ensure that the sealing rubber ring is flat and not twisted. And in this process, do not stick to oil, so as to prevent the rubber from softening, weakening the elasticity and losing the sealing effect. At the same time, an appropriate amount of sealant can be applied around the piston rod sealing ring, and the application should be continuous, uniform and uninterrupted.
3. The next thing to note is that when installing the piston rod of the equipment, especially during the process of installing the cylinder liner, make sure to press the cylinder liner into place evenly with both hands. And check that the height of each cylinder is higher than the upper plane of the cylinder block, so as not to deform the cylinder head or seal tightly when tightening the cylinder bolts. If conditions permit, the cylinder gasket and cylinder head should be installed without leakage.
4. When installing, you need to pay attention to the connection and fixing of the installation site. Under normal circumstances, the piston rod is connected to the piston, so the connection must be carefully determined. There are also many problems caused by abrasion at the connection site and improper connection.
The four items listed above are some issues that need to be paid attention to when installing the piston rod of the equipment. In addition, pay attention to its sealing problem during the installation process, because there are some differences between the piston seal and the piston rod seal, and the gap size is a problem that needs attention in the sealing process.
