Hydraulic fast joint prevention leakage

In the hydraulic system, whether it is a metal pipe joint, or hydraulic hose manufacturers connectors, are prone to leakage problem. The sleeve type pipe joint, mostly because of pipeline subjected to external force or large impact force, the card sets loose or pipe end deformation caused by leakage, you should check the card sleeve is losing a round, cutting edge has no defect, tube end is intact and the card sleeve nut tightening degree, also eliminate the pipeline external force. The flared fitting, mostly because of the flaring over, does not meet the quality requirements or repeated disassembly, causing the flaring deformation or crack causing leakage, the front end truncated re expanding. If the use of male and female cone top pressure seal, the leakage is due mostly to the two conical surface is damaged, can be used for grinding the conical surface grinding.
In some "from" ring on end face or the outer diameter sealing occasions, the leakage reason has the following kinds: "from" ring aging or deformation caused by leakage; "from" ring assembly is not in place, the two plane connection pressure uneven or "from" ring was cut from causing leakage; "" ring not compacting, elastic deformation caused by lack of leakage; "from" ring rabbet groove deep caused leakage. In this regard, the need to re select the identical diameter and section of coarse "from" ring, can also be provided with a sealing plane rabbet groove cutting or grinding, in order to reduce the rabbet groove depth, so that the "from" ring have enough elastic deformation (compression in general should be between 0.35-0.65mm).
For the pipe joint oil resistant rubber, wool, mild steel board, combined sealing washer or sealant leak, whatever the material, should first check the seal is damaged, and the rough situation such as deformation, aging, and then take appropriate measures.

Metal hose industry: in the financial crisis facing pressure, but the overall situation to.

Big investment has led to widespread overcapacity phenomenon, and industrial concentration is low, the structure is not reasonable, big and not strong problem is very prominent.
Enterprise independent innovation ability insufficient, pay attention to light, less investment, only the immediate interests while ignoring the long-term development, product homogenization phenomenon is obvious.
Facing the pressure of energy saving and emission reduction is still heavy metal hydraulic hose and fittings enterprise, product unit energy consumption and resource utilization and other aspects compared with the international advanced level there are still gaps. At the same time, the cost of enterprises are still hovering in the high.
