How to judge the pressure deficiency of the cylinder？

The problem of insufficient cylinder pressure is very important in the process of using the cylinder. What about diagnosing the insufficient cylinder pressure? Today, air cylinder actuator manufacture will give you a brief explanation.

The reason for insufficient cylinder pressure is analyzed.

When the engine works, the air cylinder actuator is in a closed state. If the pressure of the cylinder is insufficient, the sealing performance of the cylinder decreases. We should find out the reason and repair it in time. The causes of insufficient cylinder pressure are:

1. Piston ring side I gap, opening end gap is too large, or the labyrinth route of gas ring opening is shorter, or the seal of piston ring is worse after surface wear.
2. The excessive wear of piston and cylinder makes the clearance of cylinder larger. "The piston moves and sways in the cylinder, which affects the good sealing of piston ring and cylinder.
3. Because of the cementing and coking of the piston ring, it is stuck in the groove of the piston ring, so that the elasticity of the ring cannot be exerted and the sealing surface between the air ring and the cylinder wall is lost.

Insufficient cylinder pressure is often accompanied by various abnormal phenomena, which can be judged in the diagnosis.

1. The cold car is difficult to start. Without decompression, the car can overcome the top stop point of the piston compression stroke.
2. Increase oil consumption, exhaust from the oil inlet, and spray oil on the outside when it is serious. The spark plugs too much carbon and the surface of the electrode has wetting oil.
3. The engine runs unstable, the exhaust pipe has noice, or carburetor tempering phenomenon.
4. Water leaks into the crankcase, water droplets are discharged from the exhaust pipe, carburetor tempers, and the engine runs unsteadily. If the cylinder is measured by the jade force meter, the cylinder pressure will be obviously reduced.

What is the structure and running speed of the pneumatic device of the air cylinder actuator? I believe that people who are not in this industry should not be very familiar with it. Here's a summary from air cylinder actuator manufacture.

1. The pneumatic device structure of cylinder is very simple and portable, and the equipment is very simple in the process of installation and maintenance. During the operation of the equipment, the main medium is air, which is not easy to burn and safe to use.
2. Cylinders work mainly through the expansion of gas and the force produced by pressure in the process of using. Cylinders effectively convert the elasticity of compressed air into kinetic energy in the process of operation. The power element in the equipment is a power transmission form.
3. Cylinder's running speed is generally less than 1M/S, which is faster than that of electric and hydraulic modes. The equipment from air cylinder actuator manufacture has very reliable usability in the use process, and its service life is longer in the use process.
When the cylinder runs, its working medium is inexhaustible air, the air itself is not expensive, the equipment in the process of exhaust treatment is very simple and does not pollute the environment, the cost is relatively low, the output force and working speed of the equipment can be adjusted.
4. The number of effective actions of the air cylinder actuator can reach one million times. The life of the solenoid valve is more than 30 million times. Some valves with better quality are more than 200 million times. In the process of using the equipment, the air compression and energy storage can be effectively utilized to realize the centralized gas supply.
5. The cylinder can release energy in a short time in the process of using, so that the equipment can effectively obtain the high-speed response in intermittent motion, which can effectively achieve its buffer, so that the equipment has a strong adaptability to impact load and overload.
