Description

Technical Field

[0001] The utility model relates to the technical field of pneumatic motors, in particular to a deicing device for pneumatic motors. Background Art

[0002] At present, pneumatic airless sprayers are composed of pneumatic motors and paint hydraulic pumps, and the pneumatic motor is the core part of the pneumatic airless sprayer, which is equivalent to the heart of the sprayer and provides reliable power for the pneumatic airless sprayer. The pneumatic motor of the airless sprayer continuously enters the upper chamber (or lower chamber) of the cylinder through the pneumatic motor air distribution reversing mechanism to push the piston upward or downward, and the compressed air in the lower chamber (or upper chamber) of the cylinder must be instantly discharged into the atmosphere through the muffler 1. When compressed air is discharged into the atmosphere instantly, its volume will expand, thereby absorbing heat, making the temperature of the muffler exhaust hole and the exhaust channel lower and lower, causing the moisture in the air to gradually turn into ice, blocking the exhaust channel. In severe cases, the exhaust channel will be completely blocked, causing the airless sprayer to be unable to work normally; and the ice blockage phenomenon of pneumatic airless sprayers is both an inherent physical phenomenon and a difficult technical problem to solve. For example, the existing Chinese utility model patent with patent number CN 201372985 Y discloses a deicing device for a pneumatic motor, and the deicing device for the pneumatic motor needs to consume a large amount of compressed air for deicing, thereby increasing energy consumption during operation.
