What is the daily maintenance of the double-shaft shredder?

Time:2021-08-11 10:08 Author:Suny Group

The double-shaft shredder is a heavy-duty metal crushing processing equipment. Due to the heavy workload and high electrical load of the equipment, it is necessary to perform comprehensive electrical equipment maintenance on the equipment regularly during daily use. It can not only ensure the work safety of electrical equipment, but also guarantee production safety, production efficiency, and personnel safety.

Double Shredder Machine

The electrical appliances used in the double-shaft shredder involve transformers, high-voltage switch cabinets, electric control cabinets, power distribution cabinets, circuit systems, motors, etc. These equipment generally do not require regular maintenance like vulnerable parts, so they will be maintained in the equipment instead. The specific electrical equipment includes the following aspects:

Double shaft shredder 1. Transformer:

1. Clean the external dust and other dirt once a year, and tighten the conductor connecting bolts.

2. The double-shaft shredder has been stopped for more than 72 hours. Insulation test should be done before it is put into operation again, measured with a 2500V shake meter, once to the second time and to the ground ≥300MΩ, the second time to the ground ≥100MΩ, the iron core to the ground ≥5MΩ. If it cannot be reached, it should be dried.

3. Check the on-load voltage regulating switch once a month, and check whether there is corona phenomenon on the switch terminal of the machine when it is dark or dark. If so, wipe it clean with absorbent cotton yarn after power failure.

2. High voltage switch cabinet:

1. Make regular daily inspections to check whether the connecting bolts in the cabinet are loose.

2. Clean up the dust and dirt inside and outside the double-shaft shredding cabinet once a year, tighten the conductor connecting bolts, fill the operating mechanism such as circuit breakers with lubricating oil, and conduct a high-voltage preventive test once a year for maintenance.

3. Low-voltage power distribution cabinet, central signal screen:

1. Check and verify the accuracy and reliability of the ammeter and voltmeter of the double-shaft shredder every year. Check the insulation parts for damage and moisture every month. Whether the connection of protective grounding is reliable.

2. Check whether the auxiliary circuit terminals and connectors are firm and reliable monthly. Check whether it is in normal working condition and whether the signal indication is accurate every month. Check whether the battery of the DC screen is normal, check the liquid level and measure the specific gravity if necessary.

3. Monthly check the auxiliary circuit components, including meters, relays, control switch buttons, protection fuses, etc. are normal. Clean up the dust and dirt inside and outside the cabinet once a year, tighten the wire connecting bolts, and check the aging of each lead wire.

4. Double shaft shredder motor and power distribution box:

1. When the double-shaft shredder is running, check whether the motor is running normally, whether there is abnormal noise, and whether the temperature of the motor is normal;

2. Whether the instrument and indicator lamp on the start control cabinet are normal; start the standby motor, test run for about 5 minutes, and check whether there is any abnormality.

The equipment of the double-shaft shredder has a high operating load. In addition to the vulnerable parts, electrical equipment with a long service life, these parts will have a certain degree of aging and oxidation under long-term operation, which will have a certain impact on production and potential safety hazards. , Timely maintenance and maintenance of the electrical system is also essential.
