How to better extend the service life of the emulsifying machine
Release time:
2019-05-06
The cost of general engineering emulsifying machine equipment is very high, so we must take good care of the engineering emulsifying machine and extend the life of the engineering emulsifying machine. In addition to minimizing the impact of harmful factors, it should also ensure the normal working load when using the engineering emulsifier. Let's introduce in detail 1. Reduce the influence of temperature. In the work, the temperature of each component has its own normal range. For example, the temperature of the general cooling water is 80-90 ℃, and the temperature of the hydraulic oil of the hydraulic transmission system is 30-60 ℃. Below or exceeding this range, it will accelerate the wear of parts, cause the deterioration of the lubricating oil, and cause the change of material performance. Try
The cost of general engineering emulsifying machine equipment is very high, so we must take good care of the engineering emulsifying machine and extend the life of the engineering emulsifying machine.
In addition to minimizing the impact of harmful factors, it should also ensure the normal working load when using the engineering emulsifier. Here to introduce in detail
1. Reduce the influence of temperature
In the work, the temperature of each component has its own normal range. For example, the temperature of the general cooling water is 80-90 ℃, and the temperature of the hydraulic oil of the hydraulic transmission system is 30-60 ℃. Below or exceeding this range, it will accelerate the wear of parts, cause the deterioration of the lubricating oil, and cause the change of material performance.
Tests have shown that the wear of the main transmission gears and bearings of various engineering emulsifying machines is 10-12 times higher when operating in -5 ℃ lubricating oil than when operating in 3 ℃ lubricating oil. 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 ℃, the oxidation rate of the oil will double for every 5 ℃ increase in the oil temperature. For this reason, during the use of the engineering emulsifier, first, it is necessary to prevent overload operation at low temperature, ensure the normal operation of the low-speed pre-temperature stage, make the emulsifier reach the specified temperature before running or working, and do not ignore its important role because there are no problems at that time. Second, it is necessary to prevent the emulsifier from running at high temperature. During the operation of the emulsifier, check the values on various temperature tables frequently, and stop immediately for inspection if any problems are found, troubleshoot in time. For a time can not find the reason, must not be treated and still make the emulsifying machine sick work. In normal work, pay attention to check the working condition of the cooling system. For water-cooled emulsifying machine, it is necessary to check and add cooling water before daily work. For air-cooled emulsifying machine, dust on the air-cooled system should also be cleaned regularly to ensure smooth cooling air duct.
2. Reduce the influence of emulsifying machine impurities
Emulsion machine impurities generally refers to dust, soil and other non-metallic substances and engineering emulsifying machine in the use of their own in the process of some metal chips, wear products. Once these impurities into the internal emulsifier, to the emulsifier with the surface, the harm is great, not only make the relative movement out of the block, accelerate the wear of parts, and will scratch with the surface, damage the lubricating oil film, so that the temperature of the parts, lubricating oil deterioration.
According to the determination, when the impurity of the emulsifier increases to 0.15 in the lubrication, the wear rate of the piston ring on the front road 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 emulsifying machines working in harsh environments and complex conditions, one must use high-quality and supporting parts, lubricating oils and greases to block the source of harmful impurities; two must do a good job in the emulsifying machine at the work site Protection work to ensure that the corresponding institutions can work normally and prevent various impurities from entering the emulsifying machine. The failure of the emulsifying machine, as far as possible to the regular repair site for repair. When repairing on site, protective measures should also be taken to prevent the replacement parts from being contaminated by dust and other impurities before entering the emulsifier.
3. Reduce various corrosion effects
The phenomenon of damage caused by chemical or electrochemical interaction between the metal surface and the surrounding medium is called corrosion. This corrosion will not only affect the normal operation of the emulsifying machine appearance equipment, but also corrode the internal parts of the emulsifying machine. Such as rain, chemical substances in the air through the emulsifying machine parts of the external channel, cracks, etc. into the inside of the emulsifying machine, corrosion of the internal parts of the emulsifying machine, accelerate the wear of the emulsifying machine, increase the failure of the emulsifying machine. Because this kind of corrosion is sometimes invisible and intangible, it is easy to be ignored, so it is more harmful. In use, the management and operation personnel should take effective measures according to the local weather conditions and air pollution at that time to reduce the impact of chemical corrosion on the emulsifying machine, and the focus is to prevent the intrusion of rainwater and chemical components in the air to the emulsifying machine.
4. Ensure normal working load
The size and nature of the working load of the engineering emulsifier have an important influence on the loss process of the emulsifier. Generally speaking, the wear of parts increases proportionally with the increase of load. When the load on the part is higher than the average design load, its wear will be intensified. In addition, when other conditions are the same, the stable load is less than the dynamic load, the wear is less, the failure is less, and the life is low. The test shows that the wear of the engine cylinder will increase 2 times when the engine works under unstable load and stable load. The engine working under normal load has a lower failure rate and a longer life. On the contrary, the overload operation of the engine, the failure rate increased significantly, life will be less than the design indicators. Often in a wide range of load changes in the amount of wear of the emulsifier is greater than the continuous and stable work of the emulsifier.
