Threaded connection Heat Oil Hydraulic Water Rotary Union Dyeing Single input / output line coolant joint

JARCH Threaded connection Heat Oil Hydraulic Water Rotary Union Dyeing Single input / output line coolant joint

A rotary joint, also referred to as a rotary joint or rotating joint, provides a mechanical seal between a stationary supply pipe and a rotating drum or cylinder to permit the flow of heat transfer media into and/or out of the rotating roll. Heat transfer media typically used with rotary joints and rotating joints include steam,water,hermal oil,coolant,air hydraulic oil.
 
BA series rotary joint consists of two large precision bearings and seals principles of design using smooth, sealed bearing and wear to a minimum, extend the service life.

Dimensions:

BAM Series --Monoflow

BAD Series -Duplex with fixed internal pipe(Used in fixed siphon)

BAR Series -Duplex with rotating internal pipe(Used in revolving siphon)

Benefits:

• Simple structure, standard product, Rapid delivery
• Two precision bearings support to ensure long-term trouble-free operation;
• Balanced mechanical seal design, reducing the load on the sealing surface of the seal wear, greatly extend the service life;
• Narrow sealing surface friction minimum;
• Standard silicon carbide pairing graphite sealing surface, can be set according to the customer with the condition;
• Anti-corrosion materials, long-term use complex conditions;
• Housing is provided with the observation hole, and friction can be observed leaks case

Applications:

• Paper Machinery

• steel, corrugating, textiles, 

• Dyeing, Rubber, Plastics, Chemical,Machine tool

Installation Instructions:
 
Your Rotary Systems rotary union is a precision component which, when installed properly, will provide a long, leak free life. Please follow these general guidelines when installing your union:
Connections
Rotary Systems unions should always be installed using flexible connections.  To avoid damage to the bearings, the union needs to find its center during operation.  It is imperative that either the shaft or the housing is not hard-piped.  
The housing of the union should be held in a vise and the flexible connection should be installed before installing the union to the machine.
Clean female threads and face of shaft prior to installation. Use Tef. pipe tape or pipe sealant on NPT threads. As a guideline, NPT threads should be hand tight plus 1- 3 turns to seal the threads. When installing parallel threads, appropriate gaskets or o-rings should be used.
There should be a slight, kink-free curve in the hose when installed on the equipment. It is essential the housing or shaft is allowed to float to compensate for any eccentricities and/or misalignment.
 
Anti-rotation
In many instances, the flexible hose connections are used for anti-rotation. Other applications require an external device for anti-rotation such as a fork around the fittings, pin, yoke or bracket.  Anti-rotation devices need to “float” to prevent damage to the union.  
Filtration
To prevent damage to the shaft or the seals, Rotary Systems requires filtration to 10 microns or less.  Failure to do so may invalidate your warranty and cause premature failure.
Lubrication
If your union has grease fittings, lubricate union with no more than two pumps of appropriate grease per fitting.
