MXB series rotary joint is designed in non-touching sealing style with the latest multi-mini-spring compensation mechanism. It has been highly recognized in rubber, plastic, leather, textile and coating industries, etc. 1.The Shell is made of precision aluminum casting alloy with attractive and smooth appearance. 2. Two high-precision bearings are used to support the entire shell for a good coaxality, which enables to run stably at a high speed for a long time. Used balanced seal method, it guarantees a long running life. Besides, its dry running capability avoids the possible damage of the rotary joint caused by the operation without the medium. 3. Used multi-mini-spring compensation mechanism and full flow area design lowers the pressure drop, hence it avoids the spring being corroded and prolongs the service life. The main seal face is designed with SIC hard alloy and excellent quality carbon graphite rings for an effective sealing and abrasion resistance. 4. The shell body is designed with an oil nipple, enables to fill lubricating grease in the bearings regularly. Multi-scupper is designed, so maintenance measures can be taken in due time in case of leakage to prevent the medium flowing inside the bearings and cause damage. 5. Disassembled-type shell makes it possible to replace the internal sealing parts rather than shutting down the machine. It is easy to check and maintain to minimize the economic loss caused by non-operation of the machine. Operating Parameter: Temperature: 120 (Above 120, consult Minxuan Please.) Rotating speed: 3000rpm Pressure: 1.2MPa Medium: water, oil

SF6 switch is a widely used high voltage electrical appliance in the power system. SF6 gas density relay is an important element used to monitor the variation of SF6 gas density in the SF6 switch body during operation. Its performance directly affects the operation safety of SF6 switch.Due to the infrequent operation of SF6 gas density relay in the field it is often found that the operation is not flexible and the contact contact is not good after a period of time and some of the temperature compensation performance of the density relay becomes worse. When the ambient temperature changes suddenly the SF6 density relay often misoperates.Therefore DL/T596-2005 "precautionary test regulations for power equipment" stipulates that each SF6 switch user should verify SF6 gas density relay regularly.From the perspective of actual operation it is necessary to carry out regular calibration of SF6 density relay and pressure gauge in field operation. The check pressure sensor with high precision and high speed A/D converter combining with the 32 bit high performance microprocessor can check the performance of A variety of SF6 gas density relay can accurately measure the movement of the signal when the current temperature pressure value arbitrary automatically when the environment temperature of 20 â?? conversion standard pressure and have A print store and U disk offload function at the same time the fault in the process of automatic identification test.Sf6 gas density relay calibrator is convenient to carry simple to operate high test accuracy strong stability and good reliability which reflects the characteristics of "intelligent" instrument.
