The number of sections of the weighbridge depends mainly on the length and tonnage of the weighbridge. The longer the weighbridge, the more knots you need. Under normal circumstances, the earth scale is composed of 2 or more scales. What kind of problems do we need to pay attention to when installing this kind of weighbridge? Today, the Shanghai Weighbridge Manufacturer Eagle Weighing Instrument will come to detail and hope to have something for everyone. help.
1. If it is a multi-unit weighing platform, it should be lifted into the foundation pit according to the overlapping sequence of the weighing platform. It is important to note that the rear weighing platform is attached to the sensor support beam of the previous weighing platform, and the joint is positioned with a cylindrical pin.
2. For a single counter weighbridge, the end of the weighing platform can be lowered first and then the other end. For a double countertop or a three countertop weighbridge, the four fittings of the first scale body are installed so that the entire scale body falls smoothly, ensuring that the connector support post is not caught.
3. For the double scale platform weighbridge, the sensor is arranged as follows:
The double scale platform weighs six sensors, a seven-hole junction box (JB), the junction box is located on the scale body I, and the scale body I is equipped with four sensors (LC1~LC4). When the product leaves the factory, the cable and junction box of LC1~LC4 are connected. LC5 and LC6 are located on the scale body II. When the cable is disconnected from the junction box, it will be bundled and then placed in the scale body of the scale body II. Remove and unpack, over the scale body I, enter the junction box, and wire according to the wiring diagram.
For the platform scale of the three-unit weighing platform, when the product leaves the factory, the cable and the junction box are released. After the binding, the cable is bolted to the scale body. When installing it on site, it needs to be taken out and unpacked, and wired according to the wiring diagram.
After the cables are connected, tighten the lock nuts of all the sealing joints on the terminal box, cover the terminal block plate and tighten the cover screws.
A desiccant bag is placed in each junction box at the factory, and the user should pay attention to it when necessary.
The junction box and the display instrument are connected with a special signal cable, and one end enters the junction box through the junction box sealing joint. Each core wire is fixed on the pad on the terminal box or on the terminal block, and the other end is connected with the metal core and the nine-core D. Connect the flat plug and insert the meter.
