The source of vibration Manufacturing tolerances of machine parts Assembly clearance Friction between parts Unbalanced rotating load Vibration cannot be avoided, but it cannot exceed one degree. Causes of increased vibration mechanical The floor of the equipment is not firmly fastened, the base table is tilted, uneven Bearing damage The center of motor axis is inconsistent with the center of the dragged mechanical axis; Poor rotor balance (Coupling damaged, Coupling bad, Coupling The center of the device is not accurate, and the load is mechanically unbalanced.) electric Three-phase voltage imbalance Motor phase loss operation Harm caused by increased vibration Causes the motor stator and rotor coils to rub against each other, between the coil and the insulation, the friction between the conductors and the housing will cause insulation damage, expansion of the insulation gap, intrusion of dust and moisture from the outside, resulting in reduced insulation resistance, and even the formation of insulation breakdown, etc. ACCIDENT. The motor's scrapped bearings are further worn out, and the load machinery connecting the vicious cycle shaft to the motor is damaged, the solder joint cracks, and the structural strength decreases. Use the wireless Q45 vibration temperature sensor to collect vibration and surface temperature of the motor, monitor working conditions, and achieve preventive maintenance. Wireless Q45 Vibration Temperature Sensor Features The QM42VT1 test head uses an all-metal zinc alloy housing for rugged durability. Flat design, comes with a 3-meter long plug cable, to meet the requirements of a narrow space installation; DX80N2Q45VT transmitter comes with a bright bi-color LED, providing vibration amplitude over limit and temperature limit local alarm indication; Using frequency-hopping spread-spectrum wireless technology, it is quick and easy to send machine-time vibration information to where it needs to be monitored. Application Automotive OEM Stamping Workshop High Power Stamping Motor Condition Monitoring - Monitoring Vibration/Temperature Drive motor spindle value of more than 100,000, not standing spare parts, according to scientific decision-making when to purchase spare parts, replacement parts time consuming. Painting workshop HVAC (Air Conditioning Ventilation System) - High Power Exhaust Fan (45-56 KW) / Fresh Air Blower (112KW) If the fan's operating condition continues to deteriorate, it will eventually stop, causing environmental or personal injury accidents, and at the same time lead to stop production losses. High voltage electrical cabinet Use wireless temperature and humidity sensors for continuous monitoring. The ventilation conditions in the electrical cabinet are poor, and the temperature and humidity are abnormal, which can easily cause abnormalities in electrical equipment. Food and beverage industry Ammonia (as refrigerant) compressor To monitor the compressor operating conditions, the wireless TL70 tower lights are sent back to the maintenance technician as over-limit alarms, and the data is transmitted to the main system via Ethernet IP Ethernet. Other objects that can be monitored: condenser, cooling tower fan, ammonia leak Refrigerated warehouse Temperature and humidity monitoring Fan vibration monitoring Logistics Warehouse sorting center Vibration temperature monitoring of conveyor bearings and roller drive motors Wireless TL70 tower light alarm signal indication heavy machine Bulk terminal and yard Vibration temperature monitoring of conveyor bearings and roller drive motors Wireless TL70 tower light alarm signal indication
