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：

一、矿物油

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。

二、合成油

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。

三、抗磨液压油

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。

四、低温液压油

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。

五、其他类型液压油

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。

注意事项：

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:

 1. Insufficient hydraulic oil level
Reason: Insufficient hydraulic oil in the tank can cause the oil pump to suck in air, resulting in unstable oil pressure.

Solution: Regularly check and replenish hydraulic oil to ensure that the liquid level in the tank is within the specified range.

2. Hydraulic oil contamination
Reason: Impurities, moisture, or air have been mixed into the hydraulic oil, causing a decrease in the fluidity and pressure transmission performance of the oil.

Solution: Regularly replace hydraulic oil, ensure the use of clean oil, check and replace the filter element.

3. Oil pump malfunction
Reason: Wear, aging, or internal leakage of the oil pump can cause unstable output pressure of the pump.

Solution: Regularly maintain and inspect the oil pump, and promptly repair or replace any faults found.

4. Valve malfunction
Reason: Malfunction or improper adjustment of control valves, relief valves, or pressure regulating valves can cause fluctuations in oil pressure.

Solution: Check and adjust the valve to ensure it is working properly. Replace the faulty valve if necessary.

5. Hydraulic system leakage
Reason: Leakage of pipelines, joints, or seals can cause a decrease in system pressure.

Solution: Regularly inspect the hydraulic system and promptly repair or replace relevant components if leaks are found.

 6. Unreasonable system design
Reason: Unreasonable hydraulic system design, such as improper oil circuit design, inappropriate component selection, etc., can lead to unstable oil pressure.

Solution: Optimize the hydraulic system design to ensure that each component is matched reasonably and that the flow and pressure requirements are met.

 7. Temperature changes
Reason: High or low hydraulic oil temperature can affect the viscosity of the oil, leading to fluctuations in oil pressure.

Solution: Monitor the hydraulic oil temperature to ensure it is within the appropriate working range. If necessary, add cooling or heating devices.

8. Hydraulic cylinder and motor malfunction
Reason: Damaged or worn seals inside hydraulic cylinders or motors can cause internal leaks and affect oil pressure stability.

Solution: Regularly check the hydraulic cylinder and motor, and promptly repair or replace any faults found.

 Summary:
The problem of unstable hydraulic pressure in hydraulic stations can be prevented and solved through regular maintenance, correct operation, and reasonable design. Ensuring that every component in the hydraulic system is in good working condition, regular inspection and maintenance can effectively improve the stability and reliability of the hydraulic system.

Q: Why doesn't the pressure gauge of my central water outlet system move, and the water tank level detects a low level alarm but still doesn't fill with water?

Answer: This is a common question that may be related to the working principle and specific faults of the system. The following is a brief explanation of the working principle of the central water outlet system, to facilitate troubleshooting:

Working principle:

1. * * Initial filtration * *: The cutting fluid is pumped by a lift pump to a vortex separator for filtration, where larger impurities are separated from the coolant by the centrifugal force of the vortex separator.
2. * * Secondary filtration * *: The relatively clean coolant flows into the bag filter barrel for secondary filtration, and then into the water tank.
3. * * Triple filtration * *: The high-pressure screw pump pumps the coolant from the water tank to the pipeline filter for triple filtration.
4. * * High pressure water outlet * *: The coolant that has been filtered multiple times is transported through pipelines to the tool water outlet hole, forming high-pressure water outlet.

Based on these steps, the corresponding working components of the fault can be preliminarily identified.

Q: Why does a clogged bag filter cause abnormal water level in the water tank and prevent water from entering the system?

Answer: Bag filter blockage is one of the common faults in the central water outlet system, and the main reasons are as follows:

1. * * Slow water intake * *: Blockage of the bag filter causes slow coolant intake into the water tank.
2. * * High pressure pump suction * *: When the system is working, the high-pressure pump continues to pump water from the water tank, but due to clogged filter bags and insufficient water level in the tank, the high-pressure pump suction occurs.
3. Pump unit damage: Air suction can cause significant damage to high-pressure pump units.

Q: How to solve the problem of clogged bag filters?

Answer: To solve the problem of clogged bag filters, the following measures can be taken:

1. Check the filter: When the water tank level is found to be abnormal, first check whether the bag filter has accumulated too many impurities.
2. * * Increase filtering accuracy * *: Improving filtering accuracy is a reliable approach. For example, our company's central effluent system uses three filters:
-Vortex pre filtration
-Bag filter (for handling relatively clean coolant)
-Pipeline filter
3. * * Extended filter bag replacement cycle * *: In harsh working conditions, the three filters greatly extend the system's bag replacement cycle.

Q: How to provide a detailed explanation of the pressure gauge and liquid level alarm faults in the future?

Answer: Afterwards, we will provide a detailed introduction to pressure gauge and liquid level alarm faults to help everyone better troubleshoot and solve these common problems.

Summary: By understanding the working principle and common faults of the central water outlet system, everyone can preliminarily troubleshoot the system faults and take corresponding solutions. I hope these answers can be helpful to you.
