Check the cause of pneumatic cylinder malfunction:
1. Insufficient lubricating oil leads to increased friction: perform appropriate lubrication. Check the consumption of the lubricator. If it is lower than the standard consumption, please readjust the lubricator.
2. Insufficient air press
Lubrication solution for pneumatic cylinders and pistons
The piston is a compressed component in a pneumatic cylinder (made of 6063-T5 aluminum tube). To prevent gas leakage from the two chambers of the piston, a piston sealing ring is provided. The wear-resistant ring on the piston can improve the guidance of the cylinder, reduce the wear of the piston sealing ring, and lower the frictional resistance. Wear resistant rings are generally made of materials such as polyurethane, polytetrafluoroethylene, and synthetic resin cloth. The width of the piston is determined by the size of the sealing ring and the length of the required sliding component
Pneumatic cylinder type
The pressure energy of compressed gas can be converted into pneumatic transmission in machinery, and pneumatic actuator components can perform it.
Pneumatic cylinders have two types of reciprocating linear motion and reciprocating oscillation. Cylinders that perform reciprocating linear motion can be divided into four types: single acting cylinders, double acting cylinders, diaphragm cylinders, and impact cylinders.
Material selection of pneumatic cylinder piston rod
When processing the piston rod of a pneumatic cylinder, if 45 steel is used. Under normal circumstances, the load on the piston rod is not large, which means it will be made of 45 steel. Due to the fact that 45 # steel is more commonly used for medium carbon quenched structural steel, it is because it will have higher strength and better machinability.
When producing piston rods from 45 # steel, especially after appropriate heat treatment, it is more practical to obtain a certain degree of toughness, ductility, and related wear resistance. Therefore, for 45 #
How to ensure that pneumatic cylinders are not damaged during use

Solution to faults in compact pneumatic cylinders
1. The pneumatic cylinder has compressed air entering, but no output.
Given this situation, the possible reasons are as follows: the upper and lower membrane chambers are connected due to membrane leakage, the upper and lower pressures are the same, and the actuator is not outputting. Due to the aging of the diaphragm during frequent operation of the aluminum profile tube in the cylinder, or when the gas source pressure exceeds the maximum working pressure of the diaphragm, it is a direct factor leading to diaphragm damage. The output rod of the actuator is se
Inspection and repair methods for pneumatic air cylinder block cracks
In order to timely understand the condition of the cylinder block, hydraulic testing is usually required to detect whether there are cracks. The actual method is to first connect the cylinder head (cylinder kit) to the cylinder block, install the gasket, and then connect the inlet pipe at the front end of the cylinder block to the outlet pipe joint of the hydraulic press. Then inject the required pressure into the cylinder water jacket and maintain it for five minutes after injection is complete.

The piston is installed in the guide rail, and the external load is connected to the piston, which is driven by compressed air.
The patent for rodless cylinders is a sealing structure design that ensures the perfect integration of the cylinder and pneumatic system. It is an efficient, high-quality, long-lasting, low-cost, and reliable design. The rodless cylinder i
What is the structure of a pneumatic cylinder?
From an internal structural analysis, the key components typically included in pneumatic cylinders are cylinder kits (cylinder barrel, pneumatic end cap, pneumatic piston, piston rod, and seals). The inner diameter of the cylinder barrel represents the specific output force of the cylinder. Under normal circumstances, the piston needs to roll smoothly back and forth inside the pneumatic cylinder, and the surface roughness of the cylinder should reach Ra0.8 μ m.
Meanwhile, the end cap is also an important component. Under normal circumstances, the correspond
What is the reason for insufficient pressure in pneumatic cylinders?
1. Cause of malfunction
1) The side clearance and opening clearance of the piston ring are too large, or the labyrinth path of the air ring opening is shortened, or the sealing of the piston ring is poor; After surface wear, its sealing performance deteriorates.
2) Excessive wear between the piston and cylinder will increase the gap between the matching cylinders, causing the piston to swing in the cylinder and affecting the good sealing between the piston ring and the cylinder.
3) Due to glue and carbon buildup, the piston ring is stuck in the piston ring
