Description
Technical Field

Background
At present, a town sewage treatment plant generally uses a pneumatic system to provide air sources for equipment such as a valve, an actuating mechanism cylinder and the like, and the air has the following advantages as the air source:
(1) the air is used as a working medium for air pressure transmission, is inexhaustible, has convenient source, is directly discharged into the atmosphere after being used, and does not pollute the environment.
(2) The working environment has good adaptability. The pneumatic transmission system works safely and reliably in the severe environments of flammability, explosiveness, dustiness, radiation, strong magnetism, vibration, impact and the like.
(3) The air has small viscosity and small flow resistance, and is convenient for medium centralized supply and long-distance delivery.
(4) The pneumatic control action is rapid, the reaction is rapid, and the required pressure and speed can be reached in a short time.
(5) The pneumatic element has the advantages of simple structure, easy processing, long service life, high reliability and easy realization of standardization, serialization and universalization.
However, existing pneumatic systems also have some disadvantages,
(1) oil, moisture, dust, etc. in the compressed air may have adverse effects, oil vapor mixed into the compressed air may accumulate in an air tank, a pipeline, etc. to form inflammable matter, which may cause explosion, and on the other hand, the lubricating oil may form an organic acid after being vaporized, which may corrode and rust metal equipment, thereby affecting the service life of the equipment.
(2) The impurities mixed in the compressed air are deposited in the channels of the elements, reducing the channel area and increasing the resistance of the pipeline. When the system is serious, blockage can be generated, so that the gas pressure signal cannot be normally transmitted, and the system is unstable and even fails to work.
(3) Saturated moisture contained in the compressed air condenses into water under certain conditions and collects in individual tube sections. In winter in the north, the condensed water can freeze and damage the pipeline and accessories, and the normal work of the pneumatic device is influenced.
(4) Impurities such as dust in the compressed air can cause abrasive action on moving parts, which reduces the efficiency of these elements due to increased leakage air and affects their service life.
Thereby increasing maintenance costs and increasing operating costs.
