Product Description
Coal mine cylinders are hydraulic system components designed specifically for the coal mining industry and are widely used in coal mining machinery, mining equipment, and various hydraulic drive systems in mining operations. High-strength materials and advanced processing technology are used to ensure stability and durability in extreme working environments, and to improve the working efficiency and safety of coal mining equipment.
Product Features
High-strength design: Select high-quality steel, after strict heat treatment process, ensure that the oil cylinder has high pressure resistance and wear resistance, adapt to the harsh working environment of coal mines.
Corrosion resistance: The surface is coated with an anti-corrosion layer, with excellent corrosion resistance, adapting to the complex environment of humid and high temperature in mines.
High sealing: The use of imported sealing rings and sealing technology can effectively prevent hydraulic oil leakage, maintain system stability, and reduce maintenance costs.
Precision machining: Each oil cylinder is precision machined and tested to ensure that the surface finish of the piston rod is high, reduce friction and wear, and extend service life.
High reliability: The design has been rigorously tested and verified, and the oil cylinder can still maintain excellent performance under long-term high-intensity work to ensure the safe operation of the equipment.

FAQ
1. How long is the service life of a coal mine cylinder?
The service life of a coal mine cylinder usually depends on the working environment and conditions of use. Under normal use, the cylinder can be used for 3 to 5 years. If it is often in a high-load, harsh environment, it is recommended to perform regular maintenance and care to extend its service life.
2. What routine maintenance is required for coal mine cylinders?
In order to ensure the normal operation of coal mine cylinders, it is recommended to regularly check the seals, piston rod surfaces, and the quality of hydraulic oil. When replacing hydraulic oil, please use mining hydraulic oil that meets the requirements and ensure that the seals are not damaged. Perform a comprehensive inspection and cleaning every 6 months to prevent impurities from entering the cylinder and affecting its working performance.
3. What is the working pressure range of the cylinder?
The working pressure range supported by our coal mine cylinders is 16 MPa to 32 MPa, and the specific working pressure will vary according to different equipment requirements and use environments. We can provide customized services according to your needs.
4. What if the cylinder leaks?
If a leak occurs, first check whether the seal is aged or damaged. It is recommended to replace the seal as soon as possible and check whether there are scratches or wear on the piston rod surface. If the leakage is serious, it is recommended to stop using it and contact professional maintenance personnel for inspection and repair.
5. Can the coal mine cylinder be customized according to my needs?
Yes, we provide comprehensive customization services. You can customize the size, installation method, sealing scheme, etc. of the cylinder according to the working environment, equipment requirements and special needs. Please contact our sales team and we will provide you with a tailor-made solution.
6. Can the cylinder work normally in extremely cold weather?
Our coal mine cylinder uses special sealing technology and hydraulic oil adapted to low temperature environments, so it can still work normally at a low temperature of -40°C. However, the specific working temperature needs to be selected according to your environment and equipment requirements. If it needs to be used in an extremely low temperature environment, it is recommended to use a special low-temperature hydraulic oil.
7. What are the installation methods of coal mine cylinders?
We provide a variety of installation methods, including axial installation, flange installation, earring installation, etc. According to your equipment structure and installation requirements, we can provide the most suitable installation method to ensure the stable operation of the cylinder.
