The loaded vehicle shall be mounted on the weighbridge platform at a constant speed and the speed shall be controlled within 5Km/h; Emergency braking is prohibited on the scale platform, and speed limit signs shall be made. Observe whether the instrument display is stable before printing or recording data each time before the vehicle is mounted on the platform. According to the introduction of the electronic weighing instrument manufacturer, the site selection for the installation of electronic weighing instrument should be avoided on the public channel as far as possible, and non metering vehicles are prohibited from passing the weighing instrument platform at high speed. When there is a vehicle on the scale, it is not allowed to cut off the power of the instrument. If the power is cut off temporarily, the vehicle shall be taken off the scale platform after the power is restored, and the meter shall be re measured after the zero point of the instrument is restored. It is forbidden to weld or use the scale platform as ground wire on the scale platform.
Waterproof work shall be done in spring and summer, and desiccant shall be placed in the weighbridge junction box without foundation pit; The sewage and drainage pipes in the shallow foundation pit weighbridge foundation pit shall be unblocked. When the temperature of the electronic scale manufacturer is low in winter, the instrument will be powered for 20 minutes before metering. The weighbridge in food processing or grain industry shall be well rat proof, and the joint shall be well waterproof when the cable is broken; Cables shall be connected with all hoses. The truck load measured each time shall not be greater than the large weight, but not less than the small weight of 20d. The author shall not allow untrained personnel to operate the instrument. Features of electronic weighbridge Cut off all power supplies for weighing and setting after work. Vehicles are strictly prohibited to stay on the weighing platform of the mining industry for a long time or overnight.
Electronic weighbridge Maintenance precautions: regularly check the limit device of the weighbridge to ensure the accuracy of the punch. Recommended electronic weighbridge If conditions permit, the chemical industry will paint the scale body every year. The weighbridge shall be checked in time to ensure its accuracy. At ordinary times, pay attention to whether there are sundries embedded between the edge of the scale and the foundation pit or between the scale body and the approach slope; Check whether there are sundries under the weighing platform around half a year; Check whether the scale platform shakes flexibly before the instrument is powered on every day.
Maintenance of the weighbridge weighing instrument: the power supply used by the weighbridge weighing instrument shall be grounded separately, and it is forbidden to be grounded together with other equipment; Grounding resistance ≤ 4W. The instrument shall use lighting power supply, and the power supply shall be stable, and there shall be no equipment producing interference on the same power supply; It is forbidden to lead 220V power supply from three-phase four wire for instrument use.
