Advantages and disadvantages of pneumatic stone grinding tools
(1) air as the medium of air pressure transmission, inexhaustible, convenient source, after use, directly discharged into the atmosphere, will not pollute the environment.(2) good working environment. In the flammable, explosive, dust, radiation, strong magnetic, vibration, impact and other harsh environment, pneumatic transmission system is safe and reliable.
The air viscosity is small, the flow resistance is small, easy to medium centralized supply and long-distance transportation.(4) pneumatic control is quick and quick response, which can achieve the required pressure and speed in a relatively short time.(5) the pneumatic component is simple in structure, easy to process, long in service life, high in reliability, and easy to realize standardization, serialization and generalization.
Of course, due to pneumatic tools used pneumatic technology is compressed air as a working medium, there must be some shortcomings:(1) because of the large compressibility of air, the speed of the cylinder changes with the change of the applied load, and the stability is poor, which has a great influence on the position and speed control.(2) at present, the pressure level of the pneumatic system (generally less than 0.8MPa) is not high, and the total output is not big.(3) the working medium (air) is not lubricated, and the system must take measures to lubricate the oil.(4) noise is large, so it is necessary to install muffler.
