Abstract
The invention relates to a deicing method and a deicing device for a pneumatic motor. Aiming at a defect that an airless sprayer cannot work normally due to the fact that when compressed air of the conventional pneumatic motor of the airless sprayer is instantaneously exhausted to the atmosphere, the volume of the air is expanded and the air absorbs heat, so that an air vent and an exhaust passage of a silencer are frozen due to low temperature and the exhaust passage is blocked, the deicing device of the invention adopts the following technical scheme: on the pneumatic motor blocked by ice, the compressed air of a main air inlet connector is led out through the deicing device to a vent of an air distributing and reversing mechanism of the pneumatic motor, and the ice in the exhaust passage is melted by means of the pressure and temperature of the compressed air, so that the continuous stable work of the pneumatic motor is ensured. The deicing device has simple design structure, convenient modification and good effect, and the service life of the reciprocating pneumatic motor of the airless sprayer or pneumatic motors with other purposes is prolonged.
