1, the purpose of equipment spot check is to find equipment anomalies or hidden dangers.

2. The purpose of maintenance is to keep the equipment in the specified state.

Second, the concept is different.

1, equipment inspection

In order to improve and maintain the original performance of production equipment, through the five senses (vision, hearing, smell, taste and touch) or with the help of tools and instruments, the designated parts (points) on the equipment are inspected in a preventive and careful manner according to the preset period and method, so that the hidden dangers and defects of the equipment can be found, prevented and treated early. This kind of equipment inspection is called spot inspection.

2. Maintenance

Maintenance refers to the inspection, testing, repair, assembly, classification and recycling of equipment and equipment. Maintenance is indispensable in life and work; It is the only way to keep tools around everyone, improve the performance and accuracy of tools, save money, improve living standards and improve the economic benefits of life and work.

Third, the work content is different.

1, equipment inspection

(1) Equipment inspection-inspection based on five senses (sight, hearing, smell, taste and touch).

(2) Minor repairs-repair and replacement of small parts.

(3) Fastening and adjustment-Fastening and adjustment of springs, belts, bolts, brakes and brakes.

2. Maintenance

(1) Cleaning: It is necessary to clean not only the surface, but also the corners, and expose the defects such as wear, noise, looseness, deformation and leakage of equipment and tooling, and eliminate them in time.

(2) Lubrication: Lack of grease leads to poor lubrication, which makes the equipment run abnormally. Excessive wear and high temperature of some parts lead to the decrease of hardness and wear resistance, and even lead to thermal fatigue and coarse grain damage. Oil and fat should be added regularly, quantitatively, qualitatively and timely.

(3) Fastening: Fasten bolts and nuts to avoid failure caused by looseness, vibration, sliding and falling parts.
