Installation and adjustment of coal feeder scale body

A, drive motor: through the end flange and quantitative coal balance body directly connected.

Two, quantitative coal feeder scale body installation: in the installation of the scale body should be as far as possible to make the surface level. The load bearing section from the warehouse to the scale body should have a certain slope, so as to reduce the pressure of the silo. The open regulator front end of the material shall not exceed the weight bearing roller of the scale body during installation.

3. Counterweight: There is a counterweight iron on the counterweight bar of the weighing body, and the counterweight iron can move back and forth on the counterweight bar. When the scale body is installed, all protective devices can be released and the counterweight iron adjusted so that the weight frame is balanced even when the weight sensor is not in contact with the pressure bar, and the cross springs are perpendicular to each other.

Four, zero adjustment: the mechanical zero of the quantitative feeding scale and the material on the belt scale weighing section can be transferred to the load sensor through the sensor press frame and weighing frame. The pressure head bolt should be installed on the pressure frame of the sensor, and then the nut should be tightened. Air balance can be achieved by adjusting the position of the counterweight iron and then adjusting the head bolt so that the pressure head can be gently pressed against the contact point of the load sensor. Generally speaking, the mechanical zero point of the scale body of the quantitative coal feeder is 5% of the rated load of the sensor. After setting the mechanical zero point, the locking nut must be used to lock the head bolt to prevent it from loosening.
