Hydraulic tube fittings can not be used to replace ordinary dedicated connector

In the hydraulic system, either a metal hydraulic tube fittings, hoses or fittings, are prone to leakage problems. For card sets of pipe joints, mostly due to the pipeline by a larger force or impact, so that the card sleeve loose or pipe end surface deformation caused by leaks, you should check whether the card sets out of round, edge or without defects, whether the pipe ends in good condition and the extent of compression hydraulic tube fittings nut, but also eliminate the pipeline force. For flared tube hydraulic tube fittings, mostly due to excessive flaring, substandard quality requirements or repeatedly demolished, resulting in flaring deformation or cracks caused by leaks, then you can be re-flared front amputated.Hydraulic tube fittings in the hydraulic system, the connecting member and the pressure tubing hydraulic tube fittings tubing between. If you use a male and female cone top pressure seal, which is mostly due to the two cone leak damage, is available on the cone grinders for grinding. For use oil sheet, wool felt, soft steel board, combination gasket sealant joints or pipe leaks, no matter what the material is, you should first check the seals for damage, deformation, aging and rough through the large, etc. and then take the appropriate measures.Hydraulic tube fittings can not be used to replace ordinary dedicated connector, because the hydraulic are can withstand a lot of stress.

The difference between the ordinary hydraulic pipe fittings and joints

The difference between the ordinary hydraulic pipe fittings and joints: the largest and most significant difference is that the hydraulic pressure is larger staggering, hydraulic oil pipe suddenly burst impact force is great. Hydraulic pipe fittings quick principle: quick-change connectors, one is with a one-way valve, one is without a check valve. Application with check valve, check valve and the gas source is connected to the end, when you disconnect the check valve closes automatically when you turn on the activity side thimble-way valve is opened. Is the use of self-locking ball is embedded in the groove, while the locking balls from hydraulic tube fittings sleeves. Preswaged sets of pipe joints of the most important aspects of pre-installed, directly affects the reliability of the seal. Generally require a dedicated hydraulic tube fittings. Small diameter joints can be pre-installed on the vise. In practice, as a parent with a joint, nut, ferrule can be pressed onto the tube. There are card sets straight couplings, sleeve type end straight through turn heads, card sets of tee joints and other types.Category  hydraulic tube fittings pipe fittings: hydraulic hose, high pressure ball valves, intent odd quick connectors, card sets fittings, welded pipe fittings, high pressure hose, transition type fittings, bite type tube fittings, tee pipe fittings, non-standard pipe fittings, flare fittings, angled fittings, rotary tube fittings, quick connectors, stainless steel pipe fittings, copper fittings.

Hydraulic fast joint to prevent leaks

Whether it is a metal pipe hose fitting , or hydraulic hose manufacturers connectors, are prone to leakage problems in the hydraulic system.
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.
The sleeve type pipe coupling, 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 compaction degree, also eliminate the pipeline external force.
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.
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 inadequate leak; "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).

Rotary joint installation

1, rotary joints after precision manufacturing, in the handling, transportation, and storage process should avoid the collision, so as not to damage the interface and internal parts.

2, to ensure the mounting shaft concentric with the connection, to ensure the good operation of the rotary joint.

3, the installation of rotary joints of threaded connection, should pay attention to the outer tube, screw in the direction of rotation of the drum to whether the corresponding screw, inner and outer tube to consistency.

The connection between the 4, the rotary joint and pipeline, must be connected using a hydraulic hose fitting (we recommend the use of flexible metal hose assembly good), the prohibition of rigid connection.

5, a rotary joint entrance as far as possible directly connected with the hose. In order to reduce joint auxiliary weight, prolong the service life of the joint.

6, the inner pipe assembly, pay attention to cooperation and the weight of the auxiliary support size. Internal rotation type rotary joint inner tube is matched with the joint with the H8/e7 recommended tolerances.

7, a rotary joint support and stopping rotation should be appropriate, generally rod diameter should be higher than the rotation stopping hole of small 2mm, so as not to affect the rotating joint free adjustment and compensation.

What are the characteristics of the metal hose material

Both ends of the joint metal hydraulic hose fitting joint mainly includes: the threaded connection, flange connection, quick coupling. Three effect of metal hose connector : reduce the pipeline installation stress compensation pipeline rated mobile location, vibration absorption pipeline system.
The stainless steel net is a metal braided hose main bearing installed in the pressure in the pipeline, and protection of metal hose, pressure according to the size and application of places in the pipeline, can choose one or more layers of stainless steel wire or strip is according to the parameters of woven by a certain form high pressure metal hose, I the company production of metal braided hose pressure range usually ask PN0.6-32.0MPa, up to 42.0MPa. The stainless steel net mainly steel wire net and steel net cover two types.

The existence of stainless steel metal hose industry problems

1 the cost of rising prices. Iron and steel as the main raw material of stainless steel metal hydraulic hose adapters production has entered the price open and transparent small profits era, rising steel prices will push the stainless steel metal hose production cost;
The brand is poor in China 2 stainless steel metal hose connector industry, international competitiveness is weak. As a result of industrial concentration is low, backward technology, low price competition can not be avoided, China stainless steel metal hose is such a huge market has no real sense of "famous brand on the international";
3 fierce competition constantly eliminated a small stainless steel metal hose enterprise.
4 R & D strength is weak, insufficient capital investment. The technology progress of our country still stays in the overseas in twentieth Century 80 time, although it is a large number of the introduction of advanced technology and production lines, but the basic support for the technology digestion and absorption of the lack of hardware and software.
5 practical technology brain drain. At present, although China has engaged in research work in some colleges and universities, a lot of ethical research, patent papers have a very high level, but combined with production practice is not close, the theory into the finished product ability is poor.
