In order to control the leakage of hydraulic system, first of all to each part of the hydraulic device leakage limit. To control the leakage by sealing device and the correct design and use, by the sealing device effectively play a role. Hydraulic device leakage reason is in many aspects, both has the design, manufacture, installation problems, there are maintenance problems. So, we must pay great attention in all aspects, basic standards are as follows:

One: The Correct Design

1. In accordance with the requirements of the host and the work environment, the correct, rational design of hydraulic system and hydraulic device, take protection measures, the necessary additional leakproof structure necessary.

2. Try to choose the number of hydraulic components and good sealing and minimize such as pipe junction. Practice has proved, hydraulic control device adopts the block type, plug-in, no tube integration is simplified piping layout, reduce the effective way of fitting. For components and fittings must use the (pipe joint, hose) should eliminate congenital leakage.

3. The correct selection and proper sealing device seals and sealing materials. Sealing groove, groove, machining accuracy, size and roughness shall strictly comply with the relevant requirements, this is to guarantee the sealing device plays a role, put an end to the basic conditions of leakage.

4. The correct selection of pipe joints, pipe and a connecting thread.

5. A reasonable layout of hydraulic pipeline system.

6. According to the environmental temperature and working conditions of hydraulic system, reasonable choice of temperature control device.

7. To take the necessary anti impact, vibration and noise measures.

Two: The Correct Processing and Assembly

1. Circuit block (plate) mounting surface hydraulic valve should be straight; the sealing surface to finishing groove, eliminate the radial scratch. Hydraulic valve and oil block (plate) and the connection circuit block (plate) connection pretightening force should be sufficient to prevent surface separation.

2. Assembly process files correctly formulate hydraulic device, assembly tools, configuration is necessary, and in strict accordance with the assembly process execution.

3. Hydraulic device before the assembly, should according to the leakage of pressure resistance standard test system element, if found, should take the corresponding measures, the problem is serious, should be replaced.

4. Keep the hydraulic cleaning components and accessories, sealing parts and fittings, in order to prevent the stained particles and pollution, and shall check the sealing surface and a connecting thread integrity.

5. It will be and the joint screw too tight, otherwise it will make some parts of serious deformation or rupture, causing leakage.

6. To avoid damage to the seal in the assembly process.

7. The correct installation of pipeline.

8. Keep clean assembly environment, avoid the dirt into the system.

9. The system is assembled, to test, observe the site system has no leakage. Leak site was found,, to take corresponding measures. Such as plate connecting element binding surface of each oil outlet to install the O sealing ring, no leakage, when necessary, can be supplemented with sealant leakage treatment. After the test, the whole system of no leakage can be loaded into the host.

Three: The Correct Maintenance

1. To maintain the system clean, prevent pollution. When necessary, can give the hydraulic station, with protective cover.

2. In the hydraulic system filter blockage promptly after cleaning or replacing the filter core. Replace or add new oil, according to the rules of filtered before injection tank.

3. Hydraulic system repair, overhaul (or replace) hydraulic components, repair parts should be kept clean. After the repair, the joints should be strong.

4. Leakage control measures of hydraulic device.
