Key points analysis of truck scale loading and unloading!
Today, I will tell you what are the key points of truck scale loading and unloading. We will divide them into four parts:
Pay attention to these during assembly:
1: First of all, make preparations for the assembly of truck scale; If the work is started without being fully prepared, it is easy to delay the process in half of the assembly, resulting in the use of unstable layout and deformation.
2: Loosen the signal wire of each load cell from the junction box, and make a response record when doing so, so as to facilitate the installation of the device in the future on the original position of the junction box.
Otherwise, if the device is in the wrong position, it will lead to a serious problem situation. Secondly, we should pay attention to that the defective line should not be cut, and the main line should also be put away;
3: Assemble the connecting screws between the two scales, which are vertical and horizontal; It is necessary to pay attention to discrimination.
4: Hold the steel ball under the scale body, and the steel shot and the steel shot pad are provided with corresponding thin iron sheet gaskets;
5: During the assembly process, pay attention to fastening the corresponding sensor signal wire to prevent crushing. It is necessary to prevent the load cell from bumping and rushing in the process of disassembly and hoisting. The above points are important to pay attention to. As long as the above points are achieved, the truck scale can be accurately assembled. However, what should be reminded here is that if the truck scale has a serious problem and cannot handle it by itself, do not force it to handle it by yourself. Be sure to ask amateur technicians to handle it, otherwise, it will have a significant effect.
Automobile scale maintenance and protection device Automobile scale is used by more and more people. Automobile scale is also called electronic automobile scale. The maintenance and protection of automobile scale is very tight, which directly affects the service life and accuracy of automobile scale (electronic automobile scale)
More and more people are installing truck scale and using truck scale. Truck scale is also called electronic truck scale. The maintenance and protection of truck scale is very tight, which directly affects the service life and accuracy of truck scale (electronic truck scale). The maintenance and protection of useful truck scale has a great impact on the low maintenance rate of truck scale. How can we maintain and protect truck scale? The above suggestions on the maintenance and protection of the conventional truck scale are expected to be helpful to all customers
Excellent weighing room staff shall:
1. Visual reflection on truck scale platform (every day)
2. Limit adjustment (first quarter)
3. Reflection on clearance of unloading bolt (half a year)
4. Reflection on the status of connectors (half a year)
5. Reflection on the sealing and connection of junction box (year)
6. Reflection on the parts that can affect the malfunction of the weighing instrument (every day
7. Reflection on instruments and instrument errors (half a year)
Truck scale instrument department:
Keep the surfaces of weighing instrument, printer and computer clean
Often reflect on whether the wiring is loose and broken, and whether the grounding wire is firm
Keep the junction box dry and clean, and dry and replace the desiccant in the box on schedule. If there is water in the box, it can be dried with an electric hair dryer.
Under the condition of net weight, when the belt scale is empty, if the zero cursor is not lit, it should be cleared before weighing
The truck scale shall be verified by the legal metrological management department on schedule
Cut off the power supply of the weighing indicator and other electrical appliances after work
The instrument needs to be started up after 5 minutes due to sudden power failure
Stop the arc welding operation on the platform
Clean the platform frequently, and there shall be no stones, coal blocks and other foreign matters stuck in the clearance and bottom of the platform
The power supply must be cut off after work and shutdown, and the platform shall not stop vehicles or goods for a long time
Weigher shall work with certificate after training
Do not turn off the instrument
Truck scale machine department:
The clearance around the truck scale platform shall not be blocked by foreign matters, and the movement shall be spontaneous. If there are foreign matters stuck, they must be removed and cleaned; Clean the platform of the scale body frequently and insist on cleaning (Jianyi: paint the outside of the scale body once a year)
Stop the belt weigher of the connector every half a year and take care of it. Coat the bearing head with butter after cleaning; It is strictly forbidden to conduct electric welding on the truck scale platform or use the scale platform as a ground wire
The limit clearance between the sensor and the platform is 2-3mm. If the clearance is inappropriate, it must be adjusted; There should be no ponding in the foundation pit. If the ponding in the foundation pit is formed due to the rainstorm ratio and other reasons, the drainage channel should be immediately removed or dredged by the pump, and the instrument can be powered on after the dry step is adopted
The maximum speed of the vehicle passing the truck scale shall not be greater than 5Km/h5, and the vehicle shall not brake violently on the scale platform; The total weight of vehicles and goods passing the truck scale should not cross the allowable axle load and additional weighing
