Abstract

The invention discloses a dry ice jet cleaning method used for a generator unit, a dry ice solution formula and a special device for the dry ice jet cleaning method. The cleaning method comprises thesteps that dry ice particles with the extremely low temperature of -78--48 DEG C are adopted to be accelerated with low-pressure air as a carrier and power, and jetted out of a jetting gun at the speed of 200-273 m / s to hit against dirt on a to-be-cleaned surface in the generator unit. The special device comprises a low-pressure air pipe, an air pressure adjusting valve, an electric flow regulating valve, a variable-speed motor, a rotary ice wheel, a dry ice tank, a vibration motor, a connecting hose, a spray nozzle, a PLC system and a cleaning machine case. The dry ice jet cleaning method hasthe advantages of being simple in operation, high in cleaning efficiency, environmentally friendly, high in installation adaptability and suitable for cleaning of all large, middle and small generators, saving energy and having no special requirements for a place.

Description

Technical field

[0001] The invention relates to a cleaning method and its special equipment, in particular to a dry ice blast cleaning method applied to a generator set, a dry ice solution formula and its special equipment. Background technique

[0002] After the generator has been running for a period of time, many parts of the generator are easily contaminated by oil from the unit: First, the stator, rotor core, and coil surfaces of the generator will be covered with oil, and a layer of oil will accumulate at the bottom of the stator. The oil pollution seriously corrodes the insulation of the stator and rotor windings and needs to be thoroughly cleaned during the overhaul of the unit; the second is the air cooler of the generator, under the influence of oil pollution, the convection air of the random group, the oil pollution will adhere to the middle of the heat sink of the air cooler The air cooler needs to be thoroughly cleaned during the overhaul of the unit. Third, the rack...
