Plum coupling installation techniques

Plum coupling installation techniques - 2020 07 - 14 plum coupling used more and more widely, but many users to install plum coupling details is not very clear, will come here for you to make a brief introduction: 1. Before installation should first check the prime mover and work machine is concentric two axis, two shaft surface have wrapping paper and bruised, plum coupling two and a half coupling inner hole whether there is sundry, inner hole edge to see if there is damaged, if there is any axis, half coupling should be clean, with a fine file handle bruised. Then check that the two and a half coupling with whether the inner hole diameter and length of prime mover, job machine diameter and shaft extension length size. General selection, make the prime mover and work machine end half coupling length less than 10 - its axial elongation 30 mm as well. 2. For ease of installation, good is two and a half coupling in a 120 - 150 incubator or preheated in the tank, to make the inner hole size up is easy to install. After installation to ensure not bulge half coupling end face of spindle nose, flush as well. Detect the distance between the two half couplings: along the two inner measure 3 - half coupling flange Reading averaged 4 points, and lengthened the period and the sum of two group of the measured size of diaphragm, the error control in 0 0. 4 mm range. 3. Alignment: use dial indicator to detect two and a half coupling flange end face and cylindrical beating, beating when external circular flange plate is less than 250 mm values should not be greater than zero. 05mm； When external circular flange plate is greater than 250 mm, beating value should not be greater than zero. The euro. 4. Install bolts: the bolt from the outer flange holes through, from another large orifice flange plate lateral wear a set of cushion cover, elastic washer, twisting on the nut, the nut with the wrench tight. Such as installing a discomfort or dismantled replacement, and does not damage the shaft and half a league, once installed, rotate freely without don't strength as well. 5. Operator instructions: plum coupling in front of the boot device should check whether the plum coupling nut loose or fall off, if you have to in a timely manner to put tight nut with a wrench. （ Source: web)
