A steel pipe shot blasting machine may encounter several common faults during its operation. Here are some common faults and their corresponding handling methods:

Abrasive blockage: Excessive accumulation of abrasives inside the shot blasting machine may cause blockage. The handling method involves stopping the machine for inspection, clearing the blocked abrasives, and ensuring unobstructed supply of abrasives in the shot blasting machine.

Fan failure: The fan is a crucial component of the shot blasting machine's exhaust system. If the fan fails, it can result in the machine's inability to operate properly or reduced cleaning efficiency. The handling method includes checking the electrical connections of the fan, cleaning the fan blades, replacing damaged fan parts, or the entire fan unit.

Uneven pipe grinding: If the steel pipe exhibits uneven grinding during the shot blasting process, it may be due to damaged or improperly adjusted blast wheels in the shot blasting machine. The handling method involves checking the wear condition of the blast wheels, adjusting the position and blasting velocity of the wheels to ensure even grinding effect.

Electrical faults: Electrical system faults can occur in the shot blasting machine, such as control panel malfunctions or circuit shorts. The handling method includes checking the electrical system connections, repairing or replacing damaged electrical components to ensure the normal operation of the electrical system.

Activation of safety devices: The shot blasting machine is equipped with various safety devices, such as overload protection and emergency stop. When these safety devices are triggered, the machine will stop running. The handling method involves investigating the triggering cause, releasing the safety device, and ensuring the proper functioning of the safety devices.

When dealing with these faults, it is recommended to shut down the shot blasting machine and disconnect the power supply. Then, conduct inspections and repairs based on the specific fault, following the operation manual or seeking technical support from the equipment manufacturer.

To reduce the occurrence of faults, regular inspection, maintenance, and upkeep of the shot blasting machine are crucial. Additionally, training the operators to ensure correct operation and maintenance of the shot blasting equipment can effectively prevent faults.
