Should you pay attention to the hydraulic fittings of the hydraulic system? Dalan Hydraulic Xiaobian to share with you! The specific considerations are as follows:

1. The requirements for installing hydraulic fittings are:

1 The line is the shortest and the turning is as small as possible;

2 The highest part of the pipeline should be equipped with an exhaust device to deflate at start-up.

2. Select the oil pipe according to the pressure and the occasion of use.

1 The oil pipe shall have sufficient strength, and the inner wall shall be smooth and clean, free from sand, rust and scale.

2 For long-term storage of pipes, it should be pickled before processing, thoroughly cleaned, washed, and inspected.

3. When installing the rubber tube, avoid sharp turns, and the bending radius R≥(9~l0)D (D is the outer diameter of the hose).

4. Do not bend near the root of the joint. The distance from the hose joint to the beginning of the bend is required to be L ≥ 6D.

5. The hose should not be twisted when working.

6. When cutting the pipe with a saw, the non-perpendicularity of the section and the axis direction should be ±0.5°, the sharp edge must be blunt and remove the iron filings, and the ellipticality of the section is allowed to be 10% when the bending tube is processed.

7, when its outer diameter
8. The suction pipe must not leak air, nor should it be too resistant to prevent cavitation from entering or sucking.

9. The oil return pipe must extend below the oil level of the fuel tank to prevent splashing and generating air bubbles.

10. The return pipe of the overflow valve cannot be directly connected to the inlet of the pump. It must pass through the fuel tank, otherwise the oil temperature will be too high.

11. All pipeline installation procedures are carried out in two steps. First, the test assembly is carried out, and the pipe joints and flanges are spot welded in a suitable position.

12. After all the pipelines have been tested and tested, they are removed and acid-washed before being officially installed.
