The micro air pump may encounter a variety of common problems during use, which may involve the performance, operation and maintenance of the air pump. Here are some common micro air pump problems and possible solutions:
First, performance issues
Slow or no breathing
Causes: The direction of the spiral blade fan may be reversed, the motor starting capacitor or winding is abnormal, the motor coil and the air pump diaphragm are damaged, the belt is too loose, the intake filter is blocked, the exhaust valve is not closed tightly, and the piston and cylinder liner are worn.
Solutions: Calibrate vane fan orientation, repair motor and vent tube, replace damaged motor coil and air pump diaphragm, adjust belt tightness, clean or replace intake filter, check and repair exhaust valve, replace worn piston ring, etc.
underpower
Reason: the power of the air pump itself is small, or the actual output power is decreased due to the pressure loss of the gas path system.
Solution: Replace the pump with a more powerful pump, or optimize the design of the gas system to reduce pressure loss.
2. Operational problems
Starting difficulty
Cause: Starting with a load, such as a vacuum at the suction port or pressure at the exhaust port before starting.
Solution: Select an air pump with an appropriate maximum starting load value at the intake and exhaust ports to ensure normal starting under the ultimate vacuum or maximum output pressure.
Electromagnetic interference
Reason: In the system with precision circuit control, the miniature air pump may produce electromagnetic interference.
Solution: Choose a micro air pump with low electromagnetic interference, or take appropriate electromagnetic shielding measures.
Third, maintenance issues
The air nozzle is loose or aging
Reason: Long time use or poor material leads to loose or aging gas nozzle.
Solution: Check and tighten the air nozzle regularly, and replace the aging air nozzle in time.
Inadequate cleaning and maintenance
Reason: After the air pump is used for a period of time, dust and dirt will accumulate inside, affecting the performance.
Solution: Clean and maintain the air pump regularly and be careful not to coat it with grease.
Improper storage
Cause: A humid or poorly ventilated environment may cause moisture or damage to the internal components of the air pump.
Solution: Store the miniature air pump in a dry and ventilated warehouse to avoid moisture.
Four, the selection of problems
Mismatched air pump type
Reason: The selection of the air pump did not fully consider the use of the environment and requirements, resulting in the selected air pump and the actual demand does not match.
Solution: According to the use of the air pump environment and requirements, choose the right type and specifications of the air pump. For example, for occasions that require pumping and pumping, micro-pumps with composite functions should be selected; For systems with large exhaust resistance, micro vacuum pumps with large exhaust capacity should be selected.
