How to exhaust hydraulic pressure
During the operation of the hydraulic system, if there is air, it will cause the system efficiency to decrease, the noise to increase, and even the equipment to be damaged. Therefore, bleeding is an important step in hydraulic system maintenance. This article will introduce in detail the methods, steps and precautions for exhausting the hydraulic system, and provide relevant hot topics based on the hot topics on the Internet in the past 10 days.
1. The importance of exhausting the hydraulic system
Air in hydraulic systems can cause the following problems:
| question | influence |
|---|---|
| System efficiency decreases | The high compressibility of air results in unstable hydraulic oil transmission pressure. |
| Increased noise | Air under high pressure will produce cavitation noise |
| Equipment damaged | Air can cause increased wear on hydraulic components |
2. Exhaust steps of hydraulic system
The following are the specific steps for bleeding the hydraulic system:
| steps | Operating Instructions |
|---|---|
| 1. Check the system | Check whether the hydraulic oil level is normal and whether the pipeline is leaking |
| 2. Start the system | Run the hydraulic pump at low speed and observe whether the pressure gauge is stable. |
| 3. Exhaust operation | Open the exhaust valve until no bubbles of hydraulic oil flow out |
| 4. Close the exhaust valve | After confirming that there are no bubbles, close the exhaust valve and check the system pressure. |
| 5. Repeat the operation | If there is still air, repeat the above steps until the system is stable |
3. Exhaust precautions
The following matters need to be paid attention to during the exhaust process:
| Things to note | Description |
|---|---|
| safe operation | Make sure the system pressure has been released to avoid high-pressure oil splashing |
| Hydraulic oil selection | Use hydraulic oil that meets standards to avoid exhaust difficulties caused by oil problems |
| Exhaust valve position | Confirm that the exhaust valve is at the highest point of the system to ensure that the air is completely exhausted |
4. Hot topics in the past 10 days and hot topics related to hydraulic exhaust
Combined with the hot topics on the Internet in the past 10 days, the following is the hot content related to hydraulic exhaust:
| hot topics | Content introduction |
|---|---|
| Intelligent hydraulic system | Discuss how to automate detection and exhaust with smart sensors |
| Environmentally friendly hydraulic oil | Effect of new environmentally friendly hydraulic oil on exhaust efficiency |
| Hydraulic failure case analysis | Share cases of hydraulic system failure caused by improper exhaust |
5. Summary
Bleeding a hydraulic system is a critical step in ensuring efficient system operation. System problems caused by air can be effectively avoided through standardized exhaust operations and precautions. At the same time, combined with current hot topics, the intelligence and environmental protection of hydraulic systems will also bring new development directions to exhaust technology.
