Maintenance of weightless scale
Weightlessness scales are also called loss-in-weight weighing scales, weight-loss feeders, weight-loss batching scales, and weight-reducing scales. It is a quantitative feeding equipment that uses the rate of material reduction per unit time to calculate the material flow. It is widely used in electric power, pharmaceutical, The food, chemical and building materials industries are used as the metering or dosing equipment for powder materials and granular materials. When the weightlessness scale is applied, press the fast feeding and slow feeding function keys to see whether the fast and slow feeders are in the posture. For the screw feeder and belt feeding mechanism, look at the feeder's forward rotation status, and observe whether the brake pedal is the same as the forward rotation indicator. If it rotates, the motor's three-phase cable should be exchanged between the two. If the brake pedal is appropriate, it can be kept rotating for a period of time to observe whether everything is normal. So how to use the weightlessness scale correctly and do a good job of maintenance? How can we use the weightlessness scale correctly? There are mainly the following three points for attention: 1. When the weightlessness scale is turned on, nothing can be placed on it, because that will cause the motor to be burned out due to excessive pressure on the motor, so you must every time you start the weightlessness scale. Check to see if there is something on it. If there is, it must be cleaned up in time before starting the machine. 2. Some powdery materials will accumulate a large amount of dust in the control box of the weightlessness scale. If things go on like this, it will short-circuit the internal circuit and damage the electrical appliances and other parts. Therefore, the control box must be cleaned every once in a while. dust. 3. The main power of the weightless scale is the motor, and the speed of the motor is very high, so when transmitting the power, it is necessary to use a geared motor to slow down. Always remember to check whether there is any abnormality in the motor and geared motor during normal application. And to maintain at intervals, add gear oil to the gear of the reducer.
