Analysis of advantages and disadvantages of several common fire resistant hydraulic fluids
In the application of hydraulic system, fire resistant hydraulic oil has attracted much attention because of its unique performance characteristics. This type of hydraulic fluid not only has excellent lubrication properties, but also maintains stable performance under extreme conditions, especially in environments close to high temperatures and fire sources, which can significantly reduce the risk of fire and explosion. This paper will analyze the advantages and disadvantages of several common fire resistant hydraulic fluids.
First, water-ethylene glycol fire resistant hydraulic oil
Advantages:
1. Excellent fire resistance: Water - glycol Fire resistance hydraulic oil is mainly composed of water and glycol, which makes it have excellent fire resistance and can effectively reduce the fire risk caused by oil leakage.
2. Good low temperature performance: Due to the addition of ethylene glycol, this hydraulic oil can still maintain good fluidity in a low temperature environment to ensure the normal operation of the hydraulic system under low temperature conditions.
3. Environmental protection: water-ethylene glycol fire resistant hydraulic oil has good biodegradability and less pollution to the environment.
Cons:
1. Relatively poor lubrication performance: Compared with mineral oil type hydraulic oil, the lubrication performance of water-glycol fire resistant hydraulic oil is weak, which may lead to increased equipment wear.
2. Poor compatibility with some materials: due to the ethylene glycol component, this hydraulic oil may chemically react with some metal and rubber materials, affecting the sealing and stability of the system.
Second, phosphate ester fire resistant hydraulic oil
Advantages:
1. Excellent fire resistance and thermal stability: phosphate anti-fire hydraulic oil has a very high flash point and spontaneous combustion point, which can maintain stable performance in high temperature environment and effectively reduce the risk of fire.
2. Good lubrication performance: phosphate anti-fire hydraulic oil has good lubrication performance, which can reduce equipment wear and extend the service life of equipment.
3. Wide temperature range: phosphate anti-fire hydraulic oil can maintain good performance in a wide temperature range, suitable for a variety of complex conditions.
Cons:
1. Expensive: Due to the high manufacturing cost of phosphate ester fire resistant hydraulic oil, its price is also relatively high, increasing the cost of use.
2. Compatibility problems with some materials: phosphate ester fire resistant hydraulic oil may react chemically with some rubber and plastic materials, resulting in reduced system tightness.
Third, synthetic anti-fire hydraulic oil
Advantages:
1. Excellent fire resistance and stability: synthetic fire resistant hydraulic oil is made of special Synthetic Base Oil, which has excellent fire resistance and stability, and can maintain stable performance under extreme conditions.
2. Good lubrication performance and extreme pressure performance: The composite fire resistant hydraulic oil has excellent lubrication performance and extreme pressure performance, which can meet the lubrication needs of various complex working conditions.
3. Environmental protection: Some synthetic fire resistant hydraulic oil has good biodegradability and less pollution to the environment.
Cons:
1. High price: The manufacturing cost of synthetic fire resistant hydraulic oil is high, and the price is relatively high.
2. Compatibility problems with some materials: some synthetic fire resistant hydraulic oil may chemically react with some rubber and plastic materials, affecting the sealing and stability of the system.
In summary, different types of fire resistant hydraulic oil have advantages and disadvantages, and it is necessary to consider comprehensively according to the specific use environment and working conditions when selecting. At the same time, it is also necessary to pay attention to the compatibility with the equipment materials during use to ensure the stable operation of the hydraulic system.
