During use, sometimes due to certain reasons, the piston rod may experience problems such as oil leakage, oil seepage, scratches, misalignment, seal leakage, and insufficient clearance between it and the guide bushing. Below are some solutions.Locking Piston RodLet's look at how to solve oil leakage during the return stroke.
I. Inspection
First, remove the worktable plate underneath, loosen the hose connector, and release the hydraulic oil from the hydraulic cylinder. Then loosen the upper connector to allow the oil to return to the tank, then loosen the cylinder cover below, and use a puller to pull the guide bushing out of the hydraulic cylinder. The guide bushing has two threaded holes.
II. Solutions
Usually, when oil leakage occurs during the return stroke, it is mostly caused by damage to the seal. We can solve this problem by replacing the seal. In addition,Locking Piston RodLet's cover some precautions.
1. The lip of the seal should handle the pressure oil; be careful not to install it backward.
2. When rotating the bushing, pay attention to the chamfer of the piston rod head so that it can be chamfered at the end of the bushing.
3. When inserting the chamfer of the bushing into the guide bushing, the bushing also needs to be pressed onto the lip of the sealing ring. Then insert the guide bushing and bushing into the piston rod together. When it enters the guide bushing, the bushing comes out.
In summary, this isLocking Piston Rodan introduction to some problems of piston rod return oil leakage. I hope that through the above introduction, you can learn more.

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.
