  In the process of maintenance of hydraulic system of hydraulic press, the following items should be taken care of.

1. During maintenance, to perfect unloading the liquid pressure in the hydraulic system, also to think together how to deal with the problems of oil hydraulic system, under special conditions, can be clean clean the oil in the hydraulic system.

2. When removing the hydraulic tubing, clean and clean the tubing near the connecting part of the tubing. After the composition, clean the tubing with clean plastic products or stone wax paper in the opening of the tubing.Cannot use cotton yarn or rag to block a tubing column, pay attention to avoid impurities mixed with together, compare the messy line in composition, should be in the connection place of each pipe which has a number of tin or plastic, in order to install, not the wrong tubing.

3. The workshop that makes up the maintenance must be kept clean, and the best place to stop in the purification workshop.Pay special attention to the placement and preparation of your work environment.

4. During the composition, all hydraulic original prices and their parts should be properly kept and placed, without loss.

5. Do not use excessive tightening force when equipment hydraulic components or pipe joints.Especially to avoid the deformation of the hydraulic element housing, the valve core of the slide valve can not slide, the separation site oil leakage and so on.

6. When converting rubber seals, don't use sharp assignments, and be careful not to touch the surface of the work.Before installation, type o sealing ring or other sealing elements shall be immersed in the oil, for use, or installed in the future, the equipment of sealing ring there should be no distortion, and to ensure that in the process of sliding lubrication function, when the equipment or maintenance, and type o sealing ring or other sealing elements shall be in contact parts of blunt wedge Angle, and avoid make the seal ring is sharp corners or burr cut.

7. Hydraulic components in the processing of high precision surface is more, the composition and installation time, don't be homework or something else will bruise on machining surface, best to choose the appropriate tools, avoid bolt hexagon parts damage, after the installation of all kinds of spare parts must be clean clean

8. In case of gravity, the hydraulic press (hydraulic cylinder and other) movable parts may fall, and the movable parts shall be firmly supported by the supporting frame.

When the hydraulic system has been used for a certain period of time, there are anomalies or shortcoming of various causes.The adjustment method cannot be taken at this moment, but the components can be discontinued.In addition to the simple repair of installation and conversion of seals or tenses after cleaning, it is important to be very careful to make up for the repair of the plant or related overhaul plant.

In the maintenance and repair, it must be well documented that this kind of record has the applicable value for the reason of the defect in the future.It can also be used as a basis for distinguishing which parts of the device are often used.When repair, should prepare the following commonly used spare parts: hydraulic cylinder seal, pump shaft seal, various type o sealing ring, solenoid valve and relief valve spring, pressure gauge, pipeline filter element, line with all kinds of pipe, hose, electromagnet and accumulator with diaphragm, etc.In addition, still need to prepare the relevant information necessary maintenance: hydraulic press using manual, hydraulic system schematic diagram, all kinds of hydraulic components catalogue, packing of product catalog as well as the function of the hydraulic oil table and so on.In the process of hydraulic system, the following items should be closely watched.

1. During maintenance, to perfect unloading the liquid pressure in the hydraulic system, also to think together how to deal with the problems of oil hydraulic system, under special conditions, can be clean clean the oil in the hydraulic system.

2. When removing the hydraulic tubing, clean and clean the tubing near the connecting part of the tubing.
