During the use of anti-corrosion diaphragm pump , overheating often occurs. At this time, we need to treat it differently. It is necessary to find out whether the pump body is overheated or the motor is overheated, and then analyze according to the specific problem.
Anti-corrosion diaphragm pump body heat
The common cause of overheating of the anti-corrosion diaphragm pump body is due to friction caused by bearing damage, or due to lack of oil in the lubrication system and poor oil quality. Therefore, after discovering that the anti-corrosion diaphragm pump body is overheated, first check whether the lubrication system is short of oil or the lubricating oil contains impurities, etc., and then check whether the bearing is damaged. If the pump body that has just been overhauled is overheated, check that the rolling bearing or bracket cover is too small. After the above inspection, the pump body still has heat. Check whether the pump shaft is bent or the two shafts are not concentric, check the impeller balance, adjust the pump shaft or adjust the concentricity of the two shafts, and clear the balance hole of the impeller to ensure the rotation of the pump shaft and the impeller. Balance and troubleshoot.
Corrosion-resistant diaphragm pump motor overheated
Anti-corrosion diaphragm pump motor overheating is one of the common faults. What are the main reasons?
The cause of overheating of the motor is mainly due to the overheating of the motor due to high or low voltage, poor transmission, malfunction of the ventilation system or failure of the unit. When the motor is overheated, it may cause insulation burnout and broken rotor bars. Therefore, when the motor is found to be overheated, other pneumatic power modes should be used for shutdown maintenance.
Motor overheating caused by voltage should be checked by the motor power supply system, and the overheating fault of the anti-corrosion diaphragm pump motor can be solved by restoring stable power supply.
In addition, the poor transmission will also cause the motor to overheat. Due to the poor transmission between the motor and the anti-corrosion diaphragm pump, the motor load is too large, and the small horse-drawn carriage phenomenon occurs. The motor overload is the temperature rise. This situation must be repaired in time, causing unit failure. Thoroughly check the traditional system of electric motor and anti-corrosion diaphragm pump. The common traditional unsatisfactory is mainly caused by lack of oil and bearing damage of the rotating bearing of the transmission system. Find out where the fault is located for replacement or lubrication.
One of the most common faults caused by overheating of the motor caused by the failure of the same subsystem is mainly due to fan damage, clogging of the ventilation passages, bearing wear and other reasons, so that the ventilation system can not complete the work that should be undertaken, causing the motor to overheat and severely burned. Coil. This kind of situation must be checked item by item to find out the cause of the fault, and the fault can be solved by smoothing the ventilation duct, repairing the fan, and replacing the bearing.
