Rotary joint installation and maintenance methods include

Rotary joint installation and maintenance methods include:1 , the rotary metal joints during handling and installation process should avoid collision or fall, or easy to produce internal parts rupture ;2, in order to avoid scratches and seal ring damage internal components and cause unnecessary downtime and maintenance , in addition to the net should be installed before fitting pipes, rollers , cylinders or cylinder all the core sand , dust , welding slag, metal debris and other foreign matter . Should pay particular attention to the new equipment , if necessary, to be added over slipping through the net ;3, try concentric installed , installed after the entire rotating metal joints within the allowable range of a free state , otherwise Hydraulic pipe fittings joints during operation causes the sealing ring when shaken by the non- normal wear and tear ;4 , due to the rotation metal joints sealing surface friction pair during operation will create friction torque must be loaded detent holes on rotation stopper lever to eliminate , avoid metal hose prematurely due to power failure , but not suitable for transfer and supporting points assembly tight, generally rod diameter smaller than the detent hole 2mm, so as not to affect the freedom of rotating metal joints regulation and compensation ;5, the inner pipe must be straight and accurate to ensure that when the roller rotates without wobble , so to avoid damage to the inner member joint leakage or rupture of the graphite seal ring ;6 , rotating metal connector applications stainless steel hose and pipe connections , and metal hose should be of sufficient length , not tension or compression leaving the roller rotating metal joints deviate from the centerline movement of the metal hose installed can be used for slight shaking hands better . Metal hose as directly as possible with the rotating metal connector connected to minimize the use of pipeline accessories , to prevent adding weight to affect the use of performance rotary metal joints , metal hose connected to cope with pipes and accessories to provide appropriate support ;7 , during the operation of the rotating metal joints , without providing it with a lubricant , but in the case of medium barrier to avoid rotating metal connectors run in the dry state , otherwise it will cause carbon - graphite seal ring excessive wear ;8, the removal of the replacement seal ring to Hydraulic hose fittings  protect the parts , especially the sealing surface , do not crash , scratches, enter the foreign body.9 , because the machine is not used for long metal joints can cause internalrotation and scaling from rust , please note that the re-use may be stuck or drip situation occurred .10 , the rotation of circulating medium heat metal connector body should be gradually warming up, to avoid abrupt changes in temperature .11 , as in the course of a leak , you should immediately stop using and prepare maintenance , does not allow to work sick , so as not to damage other components.
