Construction machinery chassis parts are easily damaged during use. While there are many ways to repair equipment lining construction machinery chassis parts, there are still many ways to repair equipment. You can’t cut your losses by just thinking about repairs. How to extend the service life of construction machinery chassis accessories?
Anomalous damage is usually caused by thermal shock. When the steam in the container jacket condenses, a vacuum will be formed, which will bring the heat exchange medium from the circulating layer back to the jacket, thereby damaging the construction machinery chassis layer. The input material is heated by steam, which is then turned off and the steam in the jacket condenses to form a vacuum. If the cold water connected to the jacket is not turned off, the cold water will flow back and hit the vessel walls.
This can lead to large temperature changes and the damaged surface is too large to use nails or other repair methods, only heavy. If corrosion is not found for an extended period of time, it will eventually be damaged. Sudden temperature damage can sometimes occur even without exceeding the maximum temperature difference allowed by the manufacturer.
During the operation of the equipment, due to the impact and wear of the medium, the heat pipe will be damaged or even broken. In addition, gaskets for thermowells can also fail due to pressure, temperature changes, corrosion and wear. Damage to the thermometer housing is not easy to find. Unless damaged, a damaged thermometer housing head will pass through the delivery tube into the equipment below, causing even more damage.
Media in different states in the container is moving. Some media are conductive, such as acid solutions; some are non-conductive, such as benzene or non-polar solvents, which create an electric charge. The mixing of the agitator and the free fall of the material increase the potential for static electricity. Due to electrostatic discharge, the container will explode if it contains flammable gas. The resulting static electricity will emit 50,000 to 100,000 volts or more, which can damage the bismuth construction machinery chassis parts. The increased voltage may penetrate the construction machinery chassis parts layers. Although pinholes caused by high pressure can be repaired, if the pinholes cannot be found in time, the number of holes will increase with the increase of feeding times, and eventually the equipment cannot be repaired.
Do not use other materials. The accessories are made of construction machinery chassis parts or PTFE. Steel housings and accessories are electrically insulating, but that’s hard to do.
Gasket failure may be due to unfitness for use. If the pressure is too high to fail during installation, stress relaxation caused by temperature changes can damage unsuitable or inferior gaskets. Due to the failure of the gasket, the acid leaked into the steel shell to form new hydrogen, which penetrated the steel plate and gathered at the junction of the bismuth construction machinery chassis layer and the iron tire, causing the oxide skin to explode.
Bismuth construction machinery chassis parts have high hardness and good wear resistance, but some media are abrasive, and the nozzles and accessories are severely worn.
Bismuth construction machinery chassis parts can also be alkali resistant within a certain pH value range, but the temperature of the alkali solution is lower than the temperature specified by the manufacturer, which helps to ensure the expected life of the equipment. When the medium is neutral, a problem that is not easy to find is that neutral water at a temperature of 212°f or higher will corrode the layers of construction machinery chassis parts.
