Mixing plant equipment is an indispensable equipment with good performance in infrastructure construction, and it is also a equipment with a relatively high frequency of use, which can speed up the construction period of housing construction, bridge construction, highway and railway construction, etc., and can also reduce the use of manpower. When using the equipment of the mixing plant, it is necessary to master the steps of understanding leakage and finding faults, so as to quickly solve the problem when there is leakage.
1.Equipment insulation aging: Due to the influence of various factors, the insulation material may deteriorate due to the influence of various factors, resulting in equipment leakage.
2.Equipment moisture: In a humid environment, the equipment is susceptible to moisture, resulting in a decrease in insulation performance and leakage.
3.Damage to equipment components: Damage to the components of the equipment, such as motor windings, capacitors, etc., may cause leakage of the equipment.
4.Poor wiring: Poor wiring, looseness, or falling off of the equipment may also lead to leakage of the equipment.
5.Human misoperation: When the operator is operating the equipment of the mixing plant, the misoperation may lead to the leakage of the equipment.
1.Power outage check.
First of all, the power supply should be cut off, and the wiring, components and motors of the mixing plant equipment should be checked to see if they are intact. If it is found that there is obvious aging or damage to the line, the damaged line or component should be replaced in time. At the same time, check whether the winding and wiring of the motor are good, and deal with any abnormalities in time.
2.Observe the dashboard.
Observe whether there is an abnormal indication on the dashboard of the mixing plant equipment, such as whether the ammeter and voltmeter are normal. If you find that there is an abnormal indication on the dashboard, you should check the corresponding circuits and components in time.
3.Use a megohmmeter to measure the insulation resistance.
Use a megohmmeter to measure the insulation resistance of the mixing plant equipment and check whether the insulation performance of the equipment is good. For motor windings, capacitors and other components, the insulation resistance of each phase should be measured separately in order to find out where the fault is. If it is found that the insulation resistance is lower than the standard value, the corresponding fault point should be dealt with in time.
4.Troubleshoot the faults one by one.
For complex leakage faults, the method of troubleshooting can be adopted one by one. Starting from the power supply end of the mixing plant equipment, check whether there is leakage in each line, component and motor one by one. It can be checked using tools such as a voltage tester, multimeter, etc. If a component or line is found to have leakage, it should be dealt with or replaced in time.
5.Check the grounding.
Poor grounding of the plant equipment can also lead to leakage failures. The grounding of the equipment should be checked to ensure that the grounding resistance meets the requirements of the standard. If poor grounding is found, it should be dealt with in time.
6.Check the terminal blocks and connecting wires.
The inspection of terminal blocks and connecting wires should not be neglected. These areas often leak electricity due to poor fastening or poor contact. These areas should be inspected regularly to ensure that they are well connected and secured. At the same time, it is necessary to keep the terminals and connecting wires clean to avoid hidden dangers of leakage caused by dust and dirt.
7.Maintenance.
In order to prevent the occurrence of leakage failure of the equipment of the mixing plant, the equipment should be maintained regularly. This includes inspection, fastening and cleaning of wiring, components and motors, etc., as well as regular replacement of insulation, etc. Through reasonable maintenance, the occurrence of equipment leakage failure can be effectively reduced.
8.Safety Operating Procedures.
In addition to inspecting and maintaining the equipment itself, training and education of operators should be strengthened to ensure that they are familiar with and comply with safe operating procedures. In the process of operation, misoperation and illegal operation should be avoided, so as to reduce leakage failures caused by human factors.
Although the leakage fault of the mixing plant equipment may bring certain safety hazards, as long as we take the correct method of finding and troubleshooting, we can quickly solve the problem. In actual work, it is necessary to strengthen the inspection and maintenance of equipment, find and deal with potential leakage fault points in time, and ensure the normal operation and safe production of mixing plant equipment. At the same time, improving the safety awareness and skill level of operators is also one of the important measures to prevent leakage faults.
