Furrowing machine sealing tiller normal operation and maintenance problems
- Oct 07, 2017 -

    1, before the start of the preparation work and attention of furrowing machine a, a comprehensive inspection of the mechanical seal, and ancillary equipment and pipeline installation is complete, compliance with technical requirements. B, mechanical seal before the start of the hydrostatic test, check the mechanical seal leaks. If there are more leaks, we should find out the cause and try to eliminate it. If it is still invalid, the inspection should be disassembled and reinstalled. The normal hydrostatic pressure is 2~3 kg / cm2. C, according to the pump rotate to turning check whether a uniform. Such as turning demanding or not move, it should check whether the assembly size error installation is reasonable.


    2, a installation and outage, before the start should be kept sealed cavity filled with liquid. For conveying the solidified medium, steam is used to heat the sealing chamber and melt the medium. Before the start must be turning in order to prevent the sudden start caused by soft ring fragmentation. B, for the use of pump oil sealing system of the mechanical seal, the sealing oil system should be the first to start. Stop stopping the oil system after stopping. Can't stop cooling water sealed oil chamber and seal the C, after the shutdown of hot oil pump, should be the end seal oil temperature dropped to 80 degrees below, can stop the cooling water, so as not to damage the sealing parts.


    3, running a, pump start if there is a slight leakage phenomenon, should be observed for a period of time. If 4 hours of continuous operation, the leakage is still not reduced, then the pump should be checked. B, the operation of the pump pressure should be smooth, the pressure fluctuation is not greater than 1 kg / cm2. C, the pump is in operation, should avoid the evacuation phenomenon, so as to avoid damage to the sealing surface and seal dry friction. D, the seal should always check. In operation, when the leakage exceeds the standard, heavy oil is not more than 5 drops / minute, light oil is not greater than 10/, if there is still no improvement trend in 2-3 days, then the pump should be stopped to check the sealing device.
