What do you need to pay attention to when the high-temperature mesh belt is working normally? How to ensure the service life of the high-temperature mesh belt is not only related to the working environment of the high-temperature mesh belt, but also related to the maintenance of the high-temperature mesh belt. How to do it, I will explain some knowledge points about high temperature mesh belt operation or working environment for your reference and reading, for your reference:
The influence of environment on high temperature mesh belt:
1. Under the acidic or alkaline environment of high temperature mesh belt, the parts will appear stress corrosion and grain corrosion. In corrosive environments, attention must be paid to the selection of materials for high-temperature mesh belt parts. Whether the high-temperature mesh belt made of martensitic stainless steel is rusty or not depends on the working conditions.
2. When the high-temperature mesh belt is stored in the open air, rain-proof measures should be taken. During storage and handling, the high-temperature mesh belt should be prevented from bumping to avoid damage to the high-temperature mesh belt. Tongjin must maintain sufficient capacity of power supply facilities and stable voltage. It is strictly forbidden to operate under phase loss. The power supply line must be a dedicated line, and temporary lines should not be used for long-term power supply.
3. The bearing should be supplemented or replaced with lubricating grease from time to time according to the environmental conditions of use (the motor seal bearing does not need to be replaced during the service life of the lubricating grease). In order to ensure the good lubrication of the high-temperature mesh belt during operation, the number of refueling shall not be less than 1000 hours/time, the bearings and motor bearings are sealed, and 2/3 of the inner and outer rings of the bearing are filled with ZL-3 lithium-based lubricating grease. Running short of oil is strictly prohibited.
4. The high temperature mesh belt exposed to corrosive materials will cause the high temperature mesh belt parts to become thinner, wear faster, and the rust on the parts affects the flexible rotation of the mesh belt hinges and rollers.
The effect of maintenance on high temperature mesh belt:
1. The high-temperature mesh belt generates greater heat due to friction at high temperatures; due to the different thermal expansion coefficients, thermal fatigue may occur when different materials are welded together. Intermittent reduction caused by thermal expansion between parts at a temperature exceeding 400 ℃ should consider creep, ( High temperature) thermal brittleness, brittleness of carbon precipitation, the effect of temperature changes (cooling and expansion). The influence of high temperature on lubrication, silicon, graphite and molybdenum disulfide lubricants all have good heat resistance. The service life of the mesh belt is that the temperature of the conveying material and the heat of the environment rises, and the strength of the conveying mesh belt will decrease as the temperature rises.
2. During the operation of the high-temperature mesh belt, it is found that there is abnormal noise in the mesh, severe heating of the motor, electrification of the casing, tripping of the switch, failure to start, etc., and it should be shut down immediately for inspection. In order to ensure safety, maintenance is not allowed during the operation of the mesh belt. After the overhaul, a test run should be carried out for about five minutes to confirm that there is no abnormal phenomenon before starting the operation.
3. The surface of the high-temperature mesh belt should be kept clean when in use, and there should be no debris at the air inlet and outlet. Regularly eliminate dust and other debris in the mesh belt and tube. The mesh belt should be stored in a dry environment to prevent the motor from getting damp.
Consider the impact of environment and maintenance on high-temperature mesh belts. I hope everyone should pay attention to it. If there is any improper operation in this area, please correct it in time, and better maintain the mesh belt, so that the life and work of the mesh belt will be longer. .
