How to repair the truck scale failure?
The structure, accuracy, stability, surface treatment, anti-corrosion, waterproof, explosion-proof and application in special industries have unique industry advantages, and have obtained a number of national patents. Do you know how to repair a truck scale when it breaks down?1, the small tonnage loading display is normal, close to 1/2 weight, the weighing value shows a sudden increase. This phenomenon is mostly caused by the gap between the longitudinal limit bolt and the roof is too small. When the load increases, the longitudinal bolt supports the roof, resulting in direction finding jacking force, which causes the display value to suddenly increase.2, small tonnage loading is normal. After the load is increased, the display value is obviously reduced, which may be due to the contact between the weighing sensor shield and the weighing platform or the improper adjustment of the load limiting device of the weighing sensor, so that the weight cannot be fully added to the weighing sensor.3, there is heavy weight on the scale, but the display is still "zero", the possible reasons are:The function key of the weighing display controller is used incorrectly and is not in the weighing display state. It may be that the total output line of the load cell is not in contact with the connector of the load cell4, the scale shaking is not flexible, the ballast does not match the display. There is filler in the gap between the scale body and the slope protection (or between the scale pit), so that the scale platform and the ramp (or pit) are connected, affecting the weighing.5, the display value after loading is much lower than the load value. Generally, the excitation power supply of the load cell fails.6, after power, the display flashes a fixed font, no measurement. Generally, the output signal of the weighing sensor is shorted with the shielding layer, so that the weighing display controller inputs a large signal and there is overload. The resistance value between the sensor and the shielding layer and the ground wire can be measured with a multimeter to find out the short circuit.7, the printer does not turn, can not work. The printer connector is not good.Over the years, the company has insisted on bringing good service and products to you, and welcome new and old customers to inquire and buy.
