Rotary joint leakage disposal

One reason: the hollow shaft and is equipped with a rotating body concentricity enough. Disposal Solution: Check the connection of fixed size and precision, adjustment and rotator.
Two reasons: equipped with low-precision machine (face severe straightness, radial, axial gap large), vibration. Disposal Solution: find the cause, repair fitted equipment.
Three reasons: the slurry, dirt and other foreign matter into friction contact surface. Disposal Solution: add filters or decontamination, the type of transformation of the bsp swivel fittings.
Four reasons: the use of pressure and temperature exceed speed and other optional rotary joint range. Handling Strategy: research on operating conditions, the research unit or ask the manufacturer, changed with the jic swivel fittings type.

Rotary joint installation Precautions

1, jic swivel fittings through precision manufacturing, the transport and storage process should avoid collision, so as to avoid damage to the interface and internal parts.
2, the installation and the connecting shaft concentric need to ensure the good functioning of the rotary joint.
3, the rotary joint threaded connection during installation, should pay attention to the inner and outer tube threaded whether the direction of rotation of the corresponding drum and threaded to the inner and outer pipes should also be consistent.
4, the connection between the rotary joint and piping must be used hose connection (we recommend the use of the company scrambling good metal hose), the absolute prohibition of rigid connection.
5, the rotary joint entrance as directly connected with the hose. To relieve joint auxiliary weight and prolong life.
6, assembly, pay attention to the size and weight of the inner tube with auxiliary support. With the inner tube and fitting within the rotating rotary joint recommended H8 / e7 tolerance fit.
7,bsp swivel fittings support and rotation stopper should be appropriate, generally rod diameter should be smaller than the rotation preventing hole 2mm, so as not to affect the free rotation of the adjusting joints and compensation.

Advantages of the rotary joint

Because of the advantages of electrical transmission and mechanical transmission hydraulic transmission with respect to the use of hydraulic drive more and more widely in various industries. Application of hydraulic jic swivel fittings increasingly widespread. If the hydraulic actuator with respect to the media source is fixed, you can use steel transport medium to actuators. If the actuator with respect to the media source has a small amount of movement (move, rotate, swing), you can use the high-pressure hose connection. If there is a hydraulic cylinder, its transmission medium is required to use in high-speed rotation of the rotary joint shaft. Currently, bsp swivel fittings is not yet standardized, relatively few manufacturers.

Product Structure rotary joint

Hydraulic jic swivel fittings work to follow the case to select Quick mode. Within a separate pipe, can be used to choose different work needs to maximize the benefits. There are two internal rotary joint precision bearings, smooth operation lasting reliable, sturdy and flexible, friction coefficient is small, it can be high speed. In general, the hydraulic bsp swivel fittings is usually used to transport equipment to the rotating equipment hydraulic medium over hydraulic actuators and the like.
Simultaneous transmission medium inlet to follow the work of the freedom to choose sides or rear to enter. Sealing surface and seals made of special material, wear-resistant, long life, corrosion resistance, not leak. Inner seal wear condition by visual appearance of the product that can prevent mechanical stop or mechanical damage to achieve preventive effect and reduce losses. Replace worn seals easy maintenance without re-purchase of new products, cost savings.

Swivel fitting installation knowledge

1, jic swivel fittings handling and storage process should avoid collision and fall, in order to avoid damage to the interface and internal parts.
2, as installed concentric to ensure the good functioning of the rotary joint.
3, the rotary joint threaded connection during installation, should pay attention to the inner and outer tube threaded whether the direction of rotation of the corresponding drum and threaded to the inner and outer pipes should also be consistent.
4, the connection between bsp swivel fittings  and the pipe, you must use a hose connected to the absolute prohibition of rigid connection.
5, the rotary joint entrance as directly connected with the hose. To relieve joint auxiliary weight and prolong life.
6, assembly, pay attention to the size and weight of the inner tube with auxiliary support. With the inner tube and fitting within the rotating rotary joint recommended H8 / e7 tolerance fit.
7, the rotary joint support and rotation stopper should be appropriate, generally rod diameter should be smaller than the rotation preventing hole 2mm, so as not to affect the free rotation of the adjusting joints and compensation.
Rotary joint with a variety of connections for connecting the device (the client can be set to a variety of different types of connections to use the device in accordance with a specific structure

bsp swivel fittings pre-installed

(1) double heads and manifolds: From lubrication pump out until all the oil inlet distributor, under relatively high pressure. Usually cold drawn seamless steel pipe, the material is 10 or 15 gauge steel. Never use severe corrosion of the pipe;
(2) to the pipeline: jic female fittings from the female swivel fitting distributor to all lubrication points inlet port (bearing hole), withstand the pressure is relatively low. Usually drawn copper, easy to bend when the pipe. There is also cold drawn seamless steel or stainless steel tube;
(3) ferrule pipe fittings the use of hose fittings to connect the face of moving parts.
. Piping layout requirements
(A) pipeline to try to avoid the heat radiation and cooling water temperature is too high or too low spray and other place, especially hose fittings;
(2) piping and other equipment should not affect the operation of the host, to be safe, reliable, easy to work, observation, maintenance;
(3) To smooth vertical and horizontal piping, neat appearance. As little as possible, or small-angle bend elbows, using a large arc, thereby reducing oil flow resistance;
When the conflict (4) installation occurs, a small tube allows bassoon, low-pressure pipe so that the high-pressure pipe;
(5) pipeline crossing each other when not in contact, shall be separated a certain distance;
(6) parallel to the pipeline joints to stagger the installation, so as not to affect the installation and removal;
