What are the special advantages of the pneumatic device of a vibrating screen?
4 、 high reliability and long service life. Electrical components of the effective action of about a million times, while the general electromagnetic valve life of more than 30 million times, and some good quality valve more than 200 million times.
Advantages of pneumatic components:1 、 pneumatic device simple structure, light, simple installation and maintenance. Medium for the air, compared to the hydraulic medium is not easy to burn, so the use of safety.2, the working medium is inexhaustible air, the air itself does not cost money. The utility model has the advantages of simple air handling, no environmental pollution and low cost. 3, the output force and work speed adjustment is very easy. The speed of the cylinder is generally less than 1M/S, faster than the hydraulic and electrical methods of action.
5, the use of compressed air, storage energy, to achieve centralized gas supply. It can release energy in short time to obtain high speed response in intermittent motion. Buffer can be realized. Strong adaptability to impact load and over load. Under certain conditions, the pneumatic device has the ability of self preservation.6 、 all pneumatic control, with fire prevention, explosion proof, moisture-proof ability. Compared with hydraulic method, pneumatic mode can be used in high temperature situation. 7, because the air flow loss is small, compressed air can be centralized supply, long-distance transmission.
