Maintenance and maintenance points of the electrical control system of the concrete mixing plant

a, lightning protection and grounding

The lightning protection of the mixing station is very important in places with heavy thunderstorms. Regularly check the connection and corrosion of the lightning protection device. If necessary, measure the resistance of the lightning protection grounding; periodically check the safety grounding of the fuselage and the anti-intererence grounding of the system. Damage should be repaired immediately.

b, electrical connection

Regularly check for hidden dangers of electrical facilities and wiring, tighten electrical connections; check the contact and fixing of electrical components to make them contact and conduct well; outdoor connection parts should be protected against dust, moisture and safety;

c. Maintenance of the weighing system

The weighing system consists of sensors, connectors (or connecting parts), amplifiers, etc. It is a vital part of the mixing station. The main points of protection are as follows:

1. Lightning strike and electric welding current burning;

2, do a good job of dust, moisture and prevent various external damage;

3, handle the connection part, so that it is firm and safe to contact;

4. Prevent the overload of abnormal materials from causing damage.

d, electrical safety

All electrical facilities shall comply with safety regulations from design to installation; all electrical equipment shall have safety precautions and safety signs, and all electrical equipment shall be protected by special switches or insurance;

e, protection and inspection of open-air electrical equipment

All open-air electrical equipment, such as the terminals of the motor, the wiring and contacts of the travel switch, regularly check the electrical condition and check the sensitivity and reliability of its operation.
