Hydraulic station加的油品种类繁多，具体选择需根据液压站的工作条件、环境温度、压力要求以及经济性等因素综合考虑。以下是一些常见的液压油类型及其适用情况：
特点：矿物油是液压站中普遍的油品，主要由矿物油基础油和各种添加剂组成，具有较好的润滑性和密封性能。常温下粘度稳定，易于加工和维护，且价格低廉。
适用场景：适用于一般工况下的液压站，尤其是温度和环境要求不是特别苛刻的场合。
特点：合成油是一种基于化学合成的液压油，具有优异的耐高温性和氧化稳定性。它可以根据使用环境的不同进行选用，如PAO（聚α烯烃）、POE（聚醚）、PAG（聚酯类）等。合成油的价格相对较高，但其性能也更加优异，适用于高温高压和特殊环境下的工业生产。
适用场景：在特殊环境温度、高压或需要高性能液压油的场合，如航空航天、军事装备等领域。
常见类型：如HM（抗磨）液压油，它是在HL液压油基础上改善了抗磨性能，具有抗氧、防锈和抗磨性的油品。抗磨损性突出，可延长高压液压油泵的寿命，是液压站中常用的油品之一。
适用场景：适用于各种需要抗磨性能的液压站，特别是工作压力较高、工作环境恶劣的场合。
特点：如HV液压油，它是在HM液压油基础上改善了粘温特性，适用于环境温度变化大的中低压液压系统。在寒冷地域，采用的液压油还应具有良好的抗低温防凝特性。
适用场景：在寒冷地区或需要液压油在低温下保持良好流动性的场合。
生物降解油：环保型液压油，由植物或动物油脂等天然物质制成，能在自然环境中迅速分解，不会对环境造成污染。但价格较高，性能可能不如矿物油和合成油。
抗燃液压液：如HFAE水包油型乳化液，具有抗燃性但润滑性较差，使用温度和使用压力有限制。
在选择液压油时，应确保油品质量合格，避免使用劣质或不符合要求的油品。
根据液压站的工作条件和要求选择合适的液压油类型和规格。
在使用过程中，应定期检查液压油的油位、油质和油温等参数，确保液压系统的正常运行。
更换液压油时，应按照规定的程序进行操作，确保将旧油排出并清洗干净油箱。
综上所述，液压站加的油品种类繁多，具体选择应根据实际情况进行综合考虑。如果您购买的是我们扬誉液压生产销售的液压站，我们建议您加IS0-VG32或者VG46标准的液压油！
There are many reasons for unstable oil pressure in hydraulic stations, usually related to the design, maintenance, and operation of the hydraulic system. Here are some common reasons and their corresponding solutions:
Solution: Regularly check and replenish hydraulic oil to ensure that the liquid level in the tank is within the specified range.
Solution: Regularly replace hydraulic oil, ensure the use of clean oil, check and replace the filter element.
Solution: Regularly maintain and inspect the oil pump, and promptly repair or replace any faults found.
Solution: Check and adjust the valve to ensure it is working properly. Replace the faulty valve if necessary.
Solution: Regularly inspect the hydraulic system and promptly repair or replace relevant components if leaks are found.
Solution: Optimize the hydraulic system design to ensure that each component is matched reasonably and that the flow and pressure requirements are met.
Solution: Monitor the hydraulic oil temperature to ensure it is within the appropriate working range. If necessary, add cooling or heating devices.
Solution: Regularly check the hydraulic cylinder and motor, and promptly repair or replace any faults found.
Answer: After the hydraulic station oil leaks, the following measures should be taken immediately to deal with it:
1. Question: What is the first step?
Answer: Close the valve. When oil leakage occurs in the hydraulic station, the valve should be immediately closed to stop the flow of hydraulic oil and prevent more hydraulic oil leakage. Closing the valve can also reduce the pressure inside the hydraulic station and lower the risk of oil leakage. Before closing the valve, make sure to shut down and cut off the main power supply.
2. Question: What is the second step?
Answer: Clean up the site. Once oil leakage is found in the hydraulic station, the site should be cleaned immediately to prevent oil contamination from spreading and causing larger accidents. During the cleaning process, appropriate protective equipment and tools should be used to ensure the safety of personnel. At the same time, the leaked hydraulic oil should be collected and properly disposed of to avoid polluting the environment.
3. Question: What is the third step?
Answer: Check for damage. After the hydraulic station oil leaks, the damage should be checked immediately for timely repair. Firstly, it is necessary to inspect the equipment and pipelines of the hydraulic station for wear, cracks, and other issues, in order to determine the specific location of the leak. Then, corresponding measures should be taken based on the damage situation, such as replacing damaged pipelines or equipment.
Question 4: What is the fourth step?
Answer: Strengthen safety management. The safety management of hydraulic stations is the key to avoiding oil leaks. Equipment and pipelines should be regularly inspected for foreign objects, damage, aging, and other issues, and maintenance should be strengthened to ensure their integrity. At the same time, professional training and assessment should be provided to the operators of the hydraulic station to improve their operational skills and safety awareness, in order to reduce unnecessary accidents.
Conclusion: Hydraulic station oil leakage is a common safety accident that poses a threat to equipment, environment, and personnel safety. Therefore, during the operation of the hydraulic station, it is necessary to strengthen safety management, regularly inspect the condition of equipment and pipelines, and strictly follow the operating procedures to operate the equipment. Once an oil leak occurs, immediate measures should be taken to ensure the safe operation of the hydraulic station.
Q: What are the reasons for the high oil temperature in the hydraulic station?
Answer: The main reasons for the high oil temperature in hydraulic stations include:
1. Overloading of the hydraulic system results in excessive friction and energy loss, leading to an increase in oil temperature
2. Excessive or insufficient hydraulic oil increases friction and energy loss, or the circulation speed of the oil in the system increases, making it difficult to dissipate heat in a timely manner
3. Oil contamination, such as impurities, moisture, or gas mixing, increases the friction of the oil, leading to an increase in oil temperature
4. Leakage in the system leads to oil loss, reducing the lubrication and cooling effectiveness of the system
5. Oil aging leads to a decrease in oil performance and thermal conductivity over time
6. Poor heat dissipation of hydraulic system, such as radiator or cooler not working or poor heat dissipation effect.
Q: How to deal with high oil temperature in hydraulic stations?
Answer: The processing methods include:
1. Check the oil system of the hydraulic station, remove blockages or replace components with high resistance to ensure smooth oil flow
2. Reasonably adjust the working load of the hydraulic station to avoid overloading and reduce friction losses
3. Regularly inspect and maintain the cooling system of the hydraulic station to ensure good cooling effect of the radiator. Consider increasing the number of radiators or enhancing their cooling capacity
4. Regularly check and replace the oil in the hydraulic station to avoid oil contamination affecting friction and reduce heat generation
5. In high temperature environments, cooling devices for hydraulic systems can be added, such as adding fans or installing coolers, to improve heat dissipation efficiency
6. During use, pay attention to controlling the working time and load of the hydraulic system to avoid excessive use leading to high oil temperature.
Through the above measures, the problem of high oil temperature in the hydraulic station can be effectively solved, ensuring the normal operation of the hydraulic system and extending its service life.
