Leakage Prevention Of High Pressure Hose Joint
- May 03, 2018 -

1. Leakage prevention of high pressure hose joint.

In the hydraulic system, whether it is a metal tube joint or a hose connection, there is a problem of leakage. For the card sleeve joint, large.

Due to the large external force or impact of the pipe, the card sleeve loosens or the pipe end deformation and causes the leakage, at this time, it should check whether the card sleeve has lost the circle and blade.

There is no defect in the mouth, whether the end of the pipe is intact, and the compression degree of the nut, etc., meanwhile, the external force of the pipe should be eliminated. For flared pipe joints, large.

Due to excessive expansion, the quality is not required or disassembled many times, resulting in the leakage of deformation or crack, and the front end can be redone.

Flaring. If the female cone is used for sealing, most of the leakage is due to the damage of the two cones, which can be ground by grinding sand. in

Some cases are sealed by means of an end or outside diameter.

2. Cause of leakage of high pressure hose connection.

There are several reasons for the leakage of high pressure hose connection: "the" ring "is aging or deformed, causing leakage; The "don" ring assembly is not in place to make the two flats.

When the surface connection is uneven or "the" ring is cut to cause leakage; The "failure" ring is not compacted, the elastic deformation is insufficient and the leakage is caused. "о"

The groove is too deep for leakage. For this, it is necessary to choose the same outer diameter and the thick section of "the" circle, also can have a stop slot.

The sealing plane is cut or ground to reduce the groove depth, so that the "circle" ring has enough elastic deformation (the compression amount should generally be in.

Between 0.35 and 0.65mm. Leakage of oil resistant rubber sheet, wool felt, soft steel board, combined seal gasket or sealant,

No matter what the material is, first check whether the sealing parts are damaged, deformation, aging and roughness, etc., then take corresponding measures.

Installation of high pressure rubber pipe joints.

(1) the rubber tube should not be excessively bent or bend at the root, at least 1.5 times of its diameter.

(2) when the hose is moved to an extreme position, it should not be pulled too tightly; it should be slack;

(3) avoid the torsion deformation of the rubber tube as much as possible;

(4) the hose shall be as far as possible from the thermal radiation component, and the necessary fashion insulation board;

(5) avoid external damage of the hose, such as long-term friction on the surface of the same component;

(6) if the rubber tube causes excessive deformation, it should be supported.
