What are the safety measures for overhauling high-pressure air compressors?
1. What are the safety measures for overhauling high-pressure air compressors?
(1) Disconnect the power circuit breaker, open the isolation switch, experience clear no voltage after the installation of ground wire or insulation partition between the isolation switch, the handcart switch should be pulled out of the complete set of power distribution device and shut the door and lock. (2). Hang "No closing, someone working!" on the breaker and isolation switch handle. The signboard. (3) The disassembled cable head must be grounded by three-phase short circuit. (4) Do a good job to prevent the air compressor driven by the air compressor (such as water pump, air compressor, induced draft fan, etc.) caused by the air compressor rotation measures, and hang on the air compressor equipment "no closing, someone working sign.
2. What are the standard items for air compressor overhaul?
The standard items of air compressor overhaul include: air compressor extraction rotor; Stator overhaul; Rotor maintenance; Bearing overhaul; Ventilation and cooling system maintenance; Maintenance of collector ring and brush device; Junction box inspection and cleaning; Assembly of air compressor; Maintenance of starting device; Insulation test, trial operation and acceptance.

3. What are the standard items for minor maintenance of air compressors?
The standard items of air compressor minor repair include: check the insulation of air compressor; Check and clean the starting device of the air compressor; Junction box inspection and cleaning;

Check whether the bearing and lubricating oil are in good condition; Check and clean commutator, collector ring and brush device; Measuring the air gap of the bearing bearing compressor; D Open the manhole and peep hole to check the inside of the air compressor; Preventive testing (to cycle time); Trial operation and acceptance.

4. What are the standard items for air compressor stator maintenance?
The standard items of stator maintenance of air compressor include: inspection and cleaning of main magnetic pole; Check and clean the reversing pole; 3 Check and clean the end cover; Bearing inspection; Brush device inspection, cleaning; Measure stator and brush device insulation.

5. What are the standard items for air compressor rotor maintenance?
The standard items of air compressor rotor maintenance include: armature core inspection and cleaning; Inspection and cleaning of armature winding; Commutator inspection and cleaning; Bearing inspection; Brush device inspection, cleaning; Measure armature winding and commutator insulation.

6. How to stipulate the maintenance cycle of air compressor in principle?
In addition to post-accident maintenance and state maintenance, after reaching the normal operation cycle, maintenance should generally be arranged regardless of whether there is a problem. The overhaul plan is based on years of operating experience, and the principles are as follows:

(1) Overhaul cycle: usually once every 2 to 3 years.

(2). Minor repair cycle: generally once every six months.

(3) Important and poor operating conditions of air compressors can be appropriately shortened according to their conditions and health conditions, large and small repair cycles. Unimportant and good operating conditions of air compressors can be appropriately extended according to their conditions and health conditions, major and minor repair cycles.

(4) High-speed operation, large capacity rolling bearing air compressor (such as 2-pole air compressor) due to the speed should be overhauled every 1 to 2 years according to the operating condition.

(5) The newly installed air compressor is generally overhauled for inspection before it is put into operation. A major overhaul should be carried out after 1 year of operation.
