Electrical aspects of flat screen printing dryer

Sometimes, there is too much dust accumulation at the relay contact inside the electrical control box of the machine, resulting in poor contact of the relay contact and making the machine unable to operate. There are many other similar problems. For example, excessive dust accumulation in madane will affect the movement and reset of the carbon brush holder, and the compression force of the spring on the carbon brush holder on the carbon brush, resulting in poor contact between the carbon brush and the commutator copper head, which will also cause difficulties in machine operation.
