Notes on installation of rubber damping joint
When installing the rubber damping joint, the flange can not rotate freely, because the bolt hole of the expansion joint on the rubber damping joint itself needs to be aligned with the expansion joint on the flange strictly. The flange can not rotate 360 degrees at will. Its sealing performance is very good, especially the expansion joint is suitable for the transportation of harmful gas in chemical industry. Secondly, in the installation test of rubber damping joint, the corresponding flange and stud should be matched, and the flange center distance and hole circle should be aligned as far as possible, and the bolt caps of each part should be tightened at one time. The pressure test can only be carried out after tightening the expansion joint cap of the bolt in circumference for several times, and the pressure test can not meet the standard at one time. That is, when the initial test pressure is 1 / 3 of the specified pressure, stop the expansion joint pressurization test, and check whether the bolt tightness of each part and the gap between the two expansion joint flanges on the contact surface are the same. In case of looseness, uneven force and inconsistent contact clearance, timely adjust the homing position, otherwise local leakage or damage will occur, affecting the normal service pressure and service life of rubber damping joint.
Lubrication method:
1. Spray in lubrication method: spray the oil mist into the cylinder and other lubrication places along with the gas, such as ultra-high pressure rubber damping joint, sliding vane rubber damping joint and screw rubber damping joint.
2. Oil ring lubrication method: use the rotating shaft to drive the oil ring on the shaft, and the oil ring will bring the oil in the oil pool into the bearing for circulating lubrication.
3. Splash lubrication: the oil is splashed to all lubricating parts by the oil rod installed on the connecting rod, so the cylinder and moving mechanism can only use the same lubricating oil. This method is usually used in small rubber damping joints without crosshead. Its disadvantage is that the oil is not easy to filter and the oil level must be strictly controlled.
4. Drip lubrication -- use the oil cup and oil pipeline to send the lubricating oil to the parts that should be filled, or fill the lubricating oil with the oil pot on time.
5. Pressure lubrication method: the pressure lubrication method is used to automatically pressure lubricate the parts with lubricating oil by machinery (such as oil pump and oiler). This method is used in large and medium rubber damping joints with crosshead.
