Roots fan overhaulCore objectives of the training
The core of user training is to enhance operators' cognitive ability on equipment structure, operation principle and common faults. Through systematic training, it ensures that employees can accurately identify typical problems such as abnormal fan noises, vibration anomalies, pressure fluctuations, etc., and master the basic data recording methods. The training needs to focus on explaining the gear gap adjustment standards, bearing lubrication cycle and other technical parameters to avoid secondary damage caused by improper operation.
safety normand operational process enhancement
Inspection and maintenance training must cover the standardization of wearing safety protective equipment, equipment power failure locking process and emergency treatment plan. In view of the unique high-pressure gas leakage risk of Roots fan, it is necessary to simulate sudden failure scenarios for drilling, and trainees are required to be proficient in the position of the emergency shutdown button and the operating sequence of the pressure relief valve. Especially emphasize the principle of absolute prohibition of electrified overhaul, and strengthen the safety awareness through the video of accident cases.
fault diagnosisCompetency-specific training
Set up fan impeller wear, seal failure, belt slippage and other typical fault models, guide the trainees to identify the type of bearing noise through the listening stick, use the vibration detector to analyze the spectral characteristics. Training needs to be combined with physical disassembly demonstration, so that trainees intuitively understand the influence of gear meshing state on the efficiency of the fan rules, master vernier calipers to measure the actual operation of rotor clearance.
Tool use and data logging specifications
Systematically explain the operation of special maintenance tools (such as hydraulic wheel puller, laser alignment instrument), emphasizing the importance of numerical calibration of torque wrench. The training needs to set up the data collection card to fill in the practical session, requiring the trainees to standardize the record of vibration value, temperature, current and other key parameters, to establish a complete awareness of the equipment health file.
Standardized workflow simulation assessment
Through role-playing simulation of maintenance work order execution scenarios, focusing on the assessment of the integrity of protective equipment wear, tool placement compliance, disassembly and installation steps logically. Setting up impeller replacement time limit challenge tasks, requiring trainees to follow theStandardized processesCompletion of the removal of old parts, with the surface cleanup, the installation of new parts of the whole process of operation, the process is interspersed with emergency situation emergency disposal test.
