Fault Classification and Troubleshooting for Blowers and Vacuum Cleaners
2022-04-15
Blowers and vacuum cleaners are categorized into two types based on whether they provide diagnostic indications when a fault occurs: faults with diagnostic indications and faults without diagnostic indications. Today’s blowers and vacuum cleaners are equipped with a comprehensive self-diagnosis program that continuously monitors the software and hardware performance of the entire system in real time. Once a fault is detected, the system immediately issues an alert—sometimes even displaying a brief textual description on the screen. Combined with the diagnostic manual provided with the system, this allows users not only to identify the cause and location of the fault but also to obtain guidance on how to troubleshoot it.
There is no diagnostic evidence indicating that the fault was caused by an incomplete blow-and-suction fault diagnosis procedure. For this type of fault, it is essential to rely on an understanding of the operational process preceding the failure, the nature of the fault phenomenon and its consequences, as well as the maintenance personnel’s familiarity with and technical proficiency in inspecting and servicing blow-and-suction fans, in order to analyze and resolve the issue. Blow-and-suction fan fault indications can be categorized into two scenarios: those where the indicator light is illuminated and those where it is not.
How to address noise caused by improper operation of blowers and fans: Install the throttle valve in an appropriate location; alter the leakage pattern; modify the cycle; add pipe clamps, etc.
The reasons for the failure of the starting resistor in the coarse yarn blower and suction fan are as follows: If the AC input power to the coarse yarn blower and suction fan is frequently switched on, or if the bypass contactor has poor contact, or if the main circuit contactor fails to close properly, or if the on-state resistance of the bypass thyristor increases, the current flow duration will be excessively long, leading to excessive charging. When the main circuit is energized simultaneously with the control signal, the starting resistor will carry both charging current and load current at the same time. The signs of a damaged starting resistor include burning, blackening and cracking of the casing. You can use a multimeter to measure its resistance value and determine whether it is functioning normally. If the resistance value of the starting resistor is zero, infinite, or outside the rated range, it indicates that the starting resistor is damaged and should be replaced with a resistor of the same specifications. Please note that before replacing the resistor, you must first identify the cause of its damage. If the damage is caused by a faulty relay contact or bypass thyristor, these components must also be replaced.
Causes and measures for the burning of electromechanical coils in blowers and vacuum pumps: Poor coil insulation, insufficient voltage, operating pressure and flow exceeding specified values, and excessive backpressure in the oil return circuit. The solenoid can be replaced; the operating voltage should be at least 90% higher than the rated voltage. Adjust the operating pressure of the reciprocating blower/vacuum pump, or use valves with higher performance. The backpressure during reciprocating checks should be below the specified value.
Internal Leakage in Recirculating Blowers: Internal leakage in recirculating blowers occurs from the side with higher oil pressure to the side with lower oil pressure. Such internal leakage reduces volumetric efficiency, exacerbates the rise in oil temperature, and compromises the positioning accuracy of the blower, preventing it from stopping accurately and stably at a specific position within the cylinder. This is one of the key performance indicators of the blower.
