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.
In short, a metal hydraulic hose fitting enterprise facing financial crisis after crisis attitude, the pace of enterprise development and the fate will be decided. The crisis will eventually become a historical moment, the pace of development will not break. Metal hose enterprise after the storm subsided to stop the tide, will be more strong, will be more mature, will be more beautiful.

JR-2 type rectangular metal hose joint rule selection

The selection of JR-2 type rectangular metal metric hydraulic hose fittings joint right is a very important project, good metal hydraulic hose couplings and joint not only can make you very worry, effort, but also more money.
Introduces the following selection of JR-2 type rectangular metal hose several criteria.
1, liquid type and temperature, according to the different liquid choose liquid species, temperature and body material metal hose.
2, the pressure of the liquid metal soft joint selection of key, so in for different pressure of the liquid must choose strong pressure resistance of the joint.
3 determine the installation size and shape after ordering products.

Pressure flange forging process, the main purpose is to obtain size

Pressure flange forging process, the main purpose is to gain size , shape drawing in full compliance with the requirements of a qualified wrought products . Hydraulic flanges forming two basic conditions, one during the deformation process can withstand the hydraulic flange round the amount of deformation required to not destroy the external structure , and second power condition that part of the equipment through a die to apply sufficient and the particular distribution of the force . Through hydraulic ferrulethe efforts of manufacturing conditions , optimizing the production process , the production of qualified workers forging wrought products is an important task . Hydraulic forging process selection is flexible flange , the flange forming a hydraulic step , the same kind of forged parts can be produced hydraulic tube fittingby different devices or different production method to complete. For example if the link on forging hammer smithy , the rough material in the same mold chamber to complete pre-forging , the final forging , stretching , rolling . Should the pressure of hydraulic forging machine , you need to use the pre- rolled forging blank . If you are using forming roll forging methods to produce , you can then add a precision roll forging shaping step and get qualified hydraulic flanges. Another example is the multi-station cold forging step shaft , forged for the same product can have different processing techniques , the use of different hydraulic flange blank , the corresponding intermediate steps are not the same , and some contain forward extrusion , some with side squeeze . The deformation stress required size is different , the service life of the mold is also a great difference .

Hydraulic fittings described hydraulic system

Pressure pipe fittings hydraulic system due to its simple structure, flexible layout , good self-lubricating components , easy , and combined with other transmission methods . Therefore, at present most of the equipment in all types of enterprises on a wide range of applications , all electrolytic tending my factory , casting machines and tipping hybrid furnace and other key equipment are used the hydraulic system . The hydraulic system of hydraulic pipe fittings are generally closed loop piping system, hydraulic system failure is difficult to locate hidden main disadvantages of Hydraulic pipe fittings drive . Equipment failure of hydraulic hose fitting system as soon as possible once the cause of the fault and immediately removed to reduce parking due to equipment caused economic losses. Engineering and technical personnel required by virtue of their professional and technical skills, basic knowledge of hydraulic fittings transmission , hydraulic fittings components and the basic principles of structural failure analysis circuit knowledge

Card sets of pipe joints double fittings is how to install

Joint treatment: Make sure the connector inside the front and back ferrule is not missing , and is in the correct position.Do not appear like the following scenario : front , back ferrule, front ferrule direction of dislocation hold against the back ferrule direction lost hold against the back ferrule to prevent such situations is this: do not easily loosen or tighten the nut, next . Pipe handling : inserthydraulic adapter surface should be smooth part intact, avoid scratches and other defects. As shown in the bottom of the tube surface is scratched , the sealing joints affected . To end the tube axis perpendicular to the tube , the tube mouth without glitches. If you want to bend hose fitting , the pipe ends to set aside a certain length , see below L value , connector manufacturers to follow the advice given value , otherwise it will affect the pipe insertion and sealing. III. Note fittings matching size and pipe size . If OD3/8inch and OD 10mm hydraulic hoses , diameter close, but not with OD10mm OD3/8inch the tube connector , and vice versa is also true . Manufacturers usually in metric fittings made ​​a mark , the installation should pay attention to distinguish .
