Difficult to start the air compressor

The difficulty in starting an air compressor can be caused by a variety of reasons. The following are some common reasons and corresponding solutions:

Common causes

1. Power problems:

   • Power not turned on: Check whether the power supply is turned on and whether the power switch is closed.
   • Maintaining power cord is damaged: Check for aging, wear or accidental damage to ensure that the power cord is intact.
   • The power plug is loose: Check whether the power plug is firm and make sure the plug is in good contact with the socket.
   • Voltage is too low or unstable: Check whether the input voltage is normal and compare it with the motor terminal voltage. The voltage is too low or unstable, which may cause the air compressor to fail to start. At this time, the power department should be asked to check the input voltage and take corresponding measures.

2. Electrical control system failure:

   • Control loop fuse blown: Check whether the fuse in the control loop is blown. If it is blown, replace a new fuse and check the circuit for overload or short circuit problems.
   • Initiator corrupt: Check the status of the starter to ensure that the starter works properly. If the starter is damaged, replace with a new starter.
   • Circuit board cables fall off or have poor contact: Check whether the cables on the circuit board are fall off or have poor contact to ensure that the circuit is well connected.
   • PLC control failure: If the air compressor adopts PLC control, check whether the PLC program is correct and whether the PLC’s electrostatic protection measures are in place. If necessary, repair the PLC program or strengthen electrostatic protection.

3. Mechanical component failure:

   • Thermal overload relay disconnected: Check whether the thermal overload relay is disconnected. If disconnected, the cause of overload should be corrected and the thermal overload relay should be reset.
   • Motor failure: Check whether the motor is operating normally, including whether the insulating layer is aging, excessive temperature causes the insulating layer to melt, and the motor is blocked, etc. Repair or replace the motor if necessary.
   • Belt Break or Slack: Check whether the belt is broken or Slack. If the belt is broken or loose, a new belt should be replaced orAdjust the tension of the belt.
   • Gear wear: Check whether the gear is worn seriously. If the gears are worn seriously, new gears should be replaced.

4. Lugranulation system failure:

   • Insufficient lubricant: Check whether the lubricant is sufficient. If it is insufficient, lubricant should be added.
   • Lutrient oil pipeline is blocked: Check whether the lubricant oil pipeline is blocked. If it is blocked, clean or replace the new lubricating oil pipeline.
   • Lutrient oil spoiled: Check whether the lubricant oil spoils, such as black color, odor, etc. If it deteriorates, new lubricating oil should be replaced.

5. Other factors:

   • Temperature sensor failure: Check whether the temperature sensor is working properly. If the sensor is faulty, contact a professional maintenance personnel for repair.
   • Air filter is blocked: Check whether the air filter is blocked. If it is blocked, clean or replace the air filter.
   • Ambient temperature is too low: In winter or cold areas, too low ambient temperature may lead to poor fluidity of lubricant and increase startup resistance. At this time, the equipment should be preheated, the ambient temperature should be increased or the use of low-temperature-resistant lubricating oil.

Solutions

1. Check the power supply and electrical control system:

   • Check the power supply problems one by one to ensure that the power supply is turned on normally.
   • Inspect fuses, starters, circuit boards and other components in the electrical control system to ensure that there is no damage or poor contact.

2. Inspect mechanical parts:

   • Inspect mechanical parts such as motors, belts, gears, etc. to ensure that there is no damage or serious wear.
   • Check whether the thermal overload relay is disconnected and reset if necessary.

3. Check the lubrication system:

   • Check whether the lubricant oil is sufficient and supplement it if it is insufficient.
   • Check whether the lubricating oil pipeline is blocked, and clean or replace it if necessary.
   • Check whether the lubricant is deteriorated and replace it if necessary.

4. Other inspectionsCheck and adjust:

   • Check the temperature sensor and air filter to ensure normal operation.
   • In winter or cold areas, preheat the equipment or use low-temperature-resistant lubricating oil.

Preventive measures

1. Regular maintenance:

   • Regular maintenance and maintenance of the air compressor, including cleaning the air filter, checking the electrical control system, checking the transmission system, etc.
   • Establish correct operating procedures to ensure that the operator operates in accordance with the procedures.

2. Train operators:

   • Train operators to improve their skills and knowledge and ensure they can operate the air compressor correctly and safely.

3. Use high-quality accessories:

   • Use high-quality accessories, such as lubricants, air filters, belts, etc., to extend the service life of the air compressor and improve its working efficiency.

Through the above methods, the problem of difficulty in starting the air compressor can be effectively solved and the normal operation of the air compressor can be ensured. If the problem persists, it is recommended to contact professional maintenance personnel for maintenance.
