How to better extend the service life of emulsifier

- Oct 19, 2020-

The cost of general engineering emulsifier equipment is very high, so we must maintain the engineering emulsifier well to extend the life of the engineering emulsifier.

In addition to minimizing the influence of harmful factors, the normal working load should also be ensured when using the engineering emulsifier. Let's introduce it in detail below

1. Reduce the influence of temperature

In work, the temperature of each component has its own normal range. For example, the temperature of the general cooling water is 80-90 degrees Celsius, and the temperature of the hydraulic oil of the hydraulic transmission system is 30-60 degrees Celsius. Lower or exceed this range will accelerate the wear of the parts, cause the deterioration of the lubricating oil, and cause the change of material properties.

Tests show that the main transmission gears and bearings of various engineering emulsifiers run in lubricating oil at -5°C, and the wear is 10-12 times greater than that in lubricating oil at 3°C. But when the temperature is too high, it will accelerate the deterioration of the lubricating oil. For example, when the oil temperature exceeds 55-60 degrees Celsius, every 5 degrees Celsius increase in the oil temperature, the oxidation rate of the oil will double. For this reason, during the use process of the engineering emulsifier, one must prevent overload operation at low temperature, ensure the normal operation of the low-speed pre-warming stage, and make the emulsifier reach the specified temperature before driving or working. Don't cause problems at that time. Ignore its important role; second, it is necessary to prevent the emulsifier from operating at high temperatures. During the operation of the emulsifier, always check the values on various thermometers, and immediately stop the machine for inspection if any problems are found, and remove the faults in time. For those who cannot find the cause for a while, we must not leave the emulsifier working without treatment. In normal work, pay attention to checking the working condition of the cooling system. For water-cooled emulsifiers, it is necessary to check before daily work and add cooling water.

2. Reduce the influence of impurities in the emulsifier

Impurities in the emulsifier generally refer to non-metallic substances such as dust and soil, and some metal scraps and wear products produced by the engineering emulsifier during use. Once these impurities enter the inside of the emulsifier and reach between the mating surfaces of the emulsifier, the harm is very great. Not only will the relative movement be blocked and the damage of the parts will be accelerated, but also the mating surface will be scratched, the lubricant film will be destroyed, and the The temperature of the parts rises and the bone oil deteriorates.

According to measurement, when the impurity of the emulsifier in the lubrication increases to 0.15%, the wear speed of the piston ring on the front of the engine will be 2.5 times larger than the normal value; when the rolling shaft enters the impurity particles, its life will be reduced by 80%-90%. Therefore, for engineering emulsifiers working in harsh environments and complex conditions, firstly, use high-quality, supporting parts and lubricating oils and greases to block the source of harmful impurities; secondly, do a good job of emulsifying machines on the job site Protective work to ensure that the corresponding mechanism can work normally and prevent various impurities from entering the inside of the emulsifier. For malfunctioning emulsifiers, try to repair them at a regular repair site. During on-site repairs, protective measures must also be taken to prevent the parts replaced during on-site repairs from being contaminated by impurities such as dust before entering the emulsifier.

3. Reduce various corrosive effects

The phenomenon that the metal surface and the surrounding medium undergo chemical or electrochemical action and suffer damage is called corrosion. This corrosion effect will not only affect the normal operation of the external equipment of the emulsifier, but also corrode the internal parts of the emulsifier. For example, rainwater, chemical substances in the air, etc. enter the emulsifier through the external passages and gaps of the emulsifier parts, corrode the inside of the emulsifier parts, accelerate the wear of the emulsifier, and increase the failure of the emulsifier. Because this kind of corrosive effect is sometimes invisible and intangible, it is easy to be overlooked, so it is more harmful. In use, management and operating personnel should take effective measures to reduce the impact of chemical corrosion on the emulsifier according to the local weather conditions and air pollution at the time. The focus is to prevent rainwater and chemical components in the air from entering the emulsifier.

4. Ensure normal working load

The size and nature of the working load of the engineering emulsifier has an important influence on the loss process of the emulsifier. Generally speaking, the wear of parts increases in proportion to the increase in load. When the load on the part is higher than the average design load, its wear will increase. In addition, when other conditions are the same, stable load has less wear than dynamic load, fewer failures, and lower life. Tests have shown that when the engine works under unstable load and works under stable load, the wear of its cylinder will increase twice. The engine working under normal load has a lower failure rate and a longer life. On the contrary, the overloaded engine has a significantly higher failure rate and a shorter life than the design index. Emulsifiers that are often subjected to large-scale load changes have more wear than those that work continuously and stably.
