The flat gate hydraulic hoists have undergone thorough evaluation and have received ministerial-level approval from the Ministry of Water Resources and Hydropower of the People's Republic of China.
Customized Welded Hydraulic Cylinders Double Acting Hydraulic Ram Rustproof
They are identified by the serial number SD113-83, and their implementation has been enforced nationwide since January 1, 1984.
These hoists have proven to be efficient and dependable in various applications across the country.
Cylinder and cylinder of the advantages and disadvantages:
1. As the pneumatic system uses pressure generally in the range of 0.2-1.0Mpa, the cylinder is the driving force and can not do high-power components. Hydraulic cylinders can be used in relatively large power devices, use the hydraulic system;
2. From the media about the air can be unlimited, with no cost and supply difficulties, the gas will be used directly into the atmosphere, convenient, with no pollution, hydraulic oil is the opposite;
3. The air viscosity is small, and the resistance to less than the hydraulic oil;
4. But the air is much larger than the compression rate of hydraulic oil, so it's working smoothly and responds far backward in this regard.
The hydraulic cylinder system is the most important component of implementation, it can convert mechanical energy of hydraulic and match with a variety of transmissions to complete all of the mechanical movement. Hydraulic cylinder has a simple structure, output force, stable and reliable performance and easy maintenance, a wide range of applications, and so on.
