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).

Hydraulic fast joint

Hydraulic fast hydraulic hose assembly is specially designed for heavy loads, the female connectormaterial for steel chrome plating, the male hose connector and the female joint lock sleeve arehardened, pressure resistance and good fatigue resistance: the use of two seal, no leakage: with self-locking function. This connection is neither a need to use the tool,but also can realize the joint line rapid assembly and disassembly, he has both endsopen closed and two open two structure.

The ends of open close type quick connector comprises a connector body, a one-wayvalve spool, sleeve, a steel ball, a spring and a sealing etc.. The joint body cavity witha one-way valve, when the two connector body are separated from, the check valveunder the action of the spring under the respective extended, and the top pressure in the conical hole of a joint body, so that the path is closed, both sides of the oil in thepipe is closed can not flow in a tube; the two push rod touching when the twoconnector body is connected at front end of the one-way valve spool, valve core is forced to leave the taper hole of the joint body, so that both sides of the pipe is communicated with the oil inside, two joint body with steel ball locking, work, coat in the spring under the ball pressure in the U slot of the joint body, the joint body is connected.

This connection is convenient to disassemble, but the structure is more complex, the local resistance loss is large, suitable for oil and gas as the pipe line system.

The ends of open type quick connector, and both ends are open only in the joint body inner cavity is not a one-way valve closed when the difference between the two separate joint body, not a closed passage. One end of the joint is composed of threepetal type hose joint is connected with a rubber tube, a joint core rubber hose jointdirectly into the fast joint.

Daily maintenance of rotary joint

1, should maintain the internal rotary hydraulic adapter fittings and pipeline cleaning roller. Special attention should be paid to the new equipment, when necessary to add filters, in order to avoid the abnormal wear of adapter caused by foreign body.
2, if the machine is not used for a long time will cause scaling and rotating hydraulic hose adapters internal rust, such as reuse will occur the death card or drip situation.
3, with the oiling device regularly oiling, ensure the reliability of the operation of the bearing rotating joint.
Swivel joint 4, the circulation body medium should be gradually warming, avoid temperature blast.
5, check the sealing surface wear change status and thickness (normal wear is 5 - 10mm); observation of the sealing surface of the friction track, appear whether three point intermittent or scratches and other problems, such as the above situation, should be replaced immediately.
6, rotary joints should be handled with care, strictly affected, so as not to damage the joint member.
7, it is strictly prohibited to foreign body into the rotary joint internal.
8 rotary joint, not long-term idle.

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.

Brief introduction of the main parts of the package plastic analysis of metallic hose

Plastic coated metal hydraulic hose adapters adopts the material of main parts of austenitic stainless steel, so as to ensure the plastic coated metal hose excellent heat resistance and corrosion resistance, metal hose plastic package operating temperature range of -196-600 DEG C, the maximum, in the actual use of the process, according to the pipeline corrosion medium of choice corresponding stainless steel grades, can ensure the package the corrosion resistance of plastic metal hose.
The annular plastic coated metal hose assembly is a corrugated pipe shaped casing closed circular, between the wave and the wave formed by a series of corrugated rings. The annular plastic coated metal hose by welding seamless pipe or tube forming process. Restricted by the way of processing, compared with the spiral corrugated pipe, the tube length is usually shorter.
Plastic coated metal hose is plastic metal hose through high precision plastic forming by a very thin wall seamless or the welding of stainless steel package. Due to the elastic properties of plastic coated metal hose profile determines the hose has good flexibility and fatigue resistance, making it very easy to absorb all kinds of motion and deformation of cyclic loading, especially has the ability to compensate for large displacement in pipeline system.
