In modern industrial operations, the stable performance of air compressors is crucial to both production efficiency and equipment longevity. However, when a compressor shuts down immediately after startup, it can disrupt planned workflows and even cause damage to the equipment. This article explores the root causes of this issue and offers practical solutions.

I. Cause Analysis

(1) Overload Protection Triggered

1. Unstable power supply—especially low voltage—can hinder motor startup, increase load, and activate the overload protection.
2. Internal motor failures such as short circuits or open circuits may cause overload conditions.
3. Mechanical jamming increases the motor’s load beyond normal levels, triggering the protection mechanism.

(2) Temperature Protection

1. Cooling system malfunctions—such as fan failure or coolant shortage—can cause poor heat dissipation and abnormal temperature rise.
2. Improper installation or poor ventilation leads to high ambient temperatures, worsening the heat buildup.

(3) Pressure Protection

1. Faulty pressure sensors or signal transmission issues can wrongly trigger shutdown commands.
2. Malfunctioning pressure regulators or pipeline blockages may lead to pressure imbalance, activating safety shutdowns.

II. Solutions and Preventive Measures

(1) Regular Maintenance and Inspection

Conduct regular inspections on power supply, motor condition, cooling systems, and pressure sensors to ensure optimal operation.

(2) Optimized Operating Environment

Enhance ventilation and prevent exposure to high temperature and humidity. Keep the cooling system clean and free from dust or debris.

(3) Choose High-Quality Equipment
