What kind of seal do you think would be best for the piston rod and cylinder gap?


Many people know that piston rods are used in the cylinder motion executive components, they are a connecting component used to support the piston work. However, during its use, there is a gap between the cylinders, so we must seal the gap.

I believe many people knowPiston rodIt is used in the cylinder movement executive components, and it is a connecting component used to support the piston work. However, there are gaps between the cylinders during its use, so we need to seal the gaps. So what is the best way to seal the gap between it and the cylinder? Let's find out together!
Generally speaking, the seal between it and the cylinder gap is mainly filled with packing. Packing seal is a dynamic seal, mainly used in mechanical industry for processing machinery and equipment moving parts, such as compressor pistons orPiston rod,and the seal between the valve stem and the fixed body of valves with linear and spiral motion. Its packing seal mainly relies on the pressure difference before and after sealing to obtain self-tightening seal. The gaps in the packing ring generally include the following gaps:
1. Cut gap: Mainly used to compensate for the wear of the packing ring
2. Axial gap: Mainly used to ensure that the packing ring can float freely, otherwise it cannot work normally.
3. Radial gap: Avoid the packing ring from being compressed due to sinking, so as to avoid deformation or damage.
From the above content, we can seePiston rodPacking seal can be used for the gap between the cylinder and the cylinder. However, when using packing seal, different packing seal structures should be selected according to the pressure difference of gas before and after sealing, the nature of gas, and the requirements for sealing.
This is a brief introduction to the piston rod. I hope you can learn more through the above introduction.

Summary of Experience with Failed Colin Column Balance Adjustment

Analyzing the causes of errors and summarizing lessons learned during work is an important way to improve work efficiency. Fault case: A Hetian injection molding machine's Collin column broke. The Collin column was replaced and the balance was adjusted, without needing any special tools.


Injection Molding Machine Accessories: Detailed Analysis of Common Temperature Problems!

Injection molding machine accessories. In co-ordinated control, the direction of the temperature sensor in the mold is critical. When placing the temperature sensor, the user must consider its shape, structure, and the direction of the cooling channels. In addition, the temperature sensor cannot be placed arbitrarily; it should be placed in an area that has a critical effect on the quality of the injection molded product. There are many ways to connect one or more high-temperature mold temperature controllers to the controller.


Injection Molding Machine Accessories: Standard Maintenance for Injection Molding Machines

Injection molding machine accessories. Everyone should formulate appropriate daily, monthly, and annual maintenance plans based on the condition of the equipment itself, and carefully implement them for each machine according to the plan. Before using the equipment every day, we should check whether each part of the equipment is normal, such as whether the machinery is working normally, whether the heating conditions of each part are normal, whether the circulating water pipes are leaking, whether the emergency stop button can cut off the motor power supply, etc.


What should be noted when repairing a faulty piston rod?

Piston rod failure is normal. The key is to pay attention to the precautions during specific maintenance. If non-professionals perform maintenance, many problems may arise. If possible, choose professional personnel. Maintenance efficiency and its own use value will be higher. We recommend that everyone should understand the following precautions when understanding piston rod maintenance.


What are some applications of piston rods?

In fact, even if we don't mention it, everyone should know quite a bit about piston rods. Of course, to ensure the efficiency of the piston rod, we must guarantee its performance and quality. If more friends are interested in this field, you can also Tel us to discuss your views, I believe this will be helpful to our work.


Connecting structure of piston rod and piston and how to choose piston rod

Piston rods offer significant advantages in practical applications, and the connecting rod structure of the piston is also unique. When used in combination, it is essential to carefully select hydraulic cylinders that demonstrate good operating and production performance. Such products will be highly reliable. The connection structure between the piston rod and piston, and the manufacturing method of the hydraulic cylinder with this piston rod, are essentially the same.


What does the mold pull rod spacing mean in the injection molding machine parameters?

The actual usable area of the template: the greater the distance between the ejector rods, the greater the actual width and height of the grinding tools that can be accommodated. Because injection molding machines need to install plastic injection molds between the moving template and the fixed template, plastic products can be processed. If the mold is to be installed between the two templates, it must pass through two adjacent ejector rods, so the shape of the mold must be smaller than the spacing between the ejector rods.
