What is the solution to the common problems of weighing machines?
What is the solution to the common problems of weighing machines? In the usual measurement verification of weighing machines, it is difficult to avoid some common faults. Sometimes, whether you are an old wet machine or a novice, you will feel confused. Today, I will sort out the solutions to common problems of the weighing machine in the whole process of weighing. Generally speaking, the solutions to common problems and problems of net weight machines are generally as follows: 1. Transmission belt deviation. The reason for the deviation of the direction: the management center of the engine, the rudder, and the intermediate frame are not the same parallel line. The installation position of the drum that is deviated in the direction of the drum is wrong. Incorrect, uneven transmission belt direction deviation (often occurring at the interface of the transmission belt) the drum rack is wrong, or the direction deviation caused by the screw loosening of the fixed drum rack on the drum rack, the conveyor belt Long-term damage and the destruction of the direction of deviation, deviation of the direction of the transmission belt caused by the load, the jogging error caused by the impact of the raw material. Solution: Adjust the axis of the engine, the rudder, and the middle frame, adjust the installation position of the same parallel line of the drum, adjust the center line and the vertical axis of the transmission belt to be vertical and the plane parallel to the wrong transmission belt connector, and correct it. The positive and leveled barrel rack of the connector can control the deviation within the allowable error. Tighten the loose anchor bolts, improve the level of inspection power of the transmission belt, adjust the damaged transmission belt to immediately repair or replace the guiding groove of the raw material, adjust the aspect ratio of the raw material and the size of the raw material, and install the raw material cache device . Manipulate the conveying capacity, improve maintenance 2. The noise of the belt conveyor is abnormal. When the belt conveyor is in normal operation, the noise is generally low, and there is a sudden loud noise. It is very likely that: the rolling bearing is destroyed; the relatively serious axial coupling of the roller has common failures, and the drive equipment and the conversion equipment come out with a gurgling noise. Solution: Immediately dismantle and replace the damaged rolling bearing; Immediately dismantle and replace the buffer roller; Immediately dismantle and replace the coupling. 3. Continuous short-circuit safety accidents. It is very likely that the reason: because of the normal damage of the long-term operation of the transmission belt, the blockage of the bulk material suddenly expanded the supporting force of the tape, causing the rupture of the transmission belt and causing the transmission belt to tear and rupture. Solution: Always check and maintain the transmission belt regularly. When selecting a transmission belt that avoids blockage of the transmission belt with blocky materials, be sure to choose a cost-effective transmission belt, and immediately repair the damaged Buchner funnel to prevent the raw material from hitting the transmission belt and destroying it. 4. Drive belt to drive. Reason: The initial supporting force is not enough, the tail end of the belt conveyor driven by the transmission belt is too dusty, and the frictional resistance is too large, and it is likely to be dragged. Solution: Improve the original supporting force of the transmission belt (which can be completed by adjusting the tensioning device of the transmission belt); ease the freight volume of the belt conveyor; dismantle and replace the drive motor with a larger output power. Solution: Improve the original supporting force of the transmission belt (it can be completed according to the tightening equipment of the transmission belt); relieve the primary load of the belt conveyor; dismantle and replace a more powerful drive motor. The belt conveyor has the advantages of simple structure, large conveying capacity, strong adaptability, low energy consumption, long life and other advantages, which are widely used in coal, fly ash, powder and other production lines. Because of the characteristics of high sliding friction and large damage in the transportation of chemical substances, the belt conveyor often produces common faults in the specific work, which endangers the smooth development of the entire processing process. Therefore, I have summarized the common faults and relative solutions that are very easy to occur in the work of the weighing machine above, and I look forward to assisting you.
