Solenoid valve installed earlier to encounter what problem?

Solenoid valve installed earlier to encounter what problem? Solenoid valve operating Cheng Li cause now. Cleaning is not thorough, careless operation, misuse of tools. In the stem, oil pressure, boundary surface didn't clean, even letter with the remaining packing; Operation is not in order, with packing, guns, packing is stained with mud; No special tools, as the cutting system using the hard packing, with a screwdriver to install packing, etc. This greatly reduce the packing installation quality. Choose improper packing, DiDai high, narrow and wide. The general low pressure filler used in high temperature and strong corrosive medium. Packing a right Angle, length is differ, installed in the condition of closed, uneven calves, imprecise. Multilayer condition, multilayer circle packing, a pressure. Make stuffing box filler uneven, has space, after compaction is tight pine, increased the packing leakage. Install too much packing pressure benefits on the stuffing box, press the prone to a tax abrade the valve stem. Pressure evolution and condition of material for the preloaded gap is too small, packing leakage in use, were unable to tighten gland. Pressure p/e of the city is too tight, increased the stem of wear, make fujian bar opening and closing force increases. Gland askew, elastic not hook. Stem and profit gap is too small, mutual friction and wear of valve stem. O charts to install prone to distortion, scratches, deformation defects such as. Our heavy east brand solenoid valve products high technology, good quality, electromagnetic valve technology comparable to international standards.
