Wire port adapter should use standardized wrench uniform force tighten, do not use afterburner rod afterburner slide wire to make the union, slippery edge and fracture, and to regularly check the pump rubber joints, so as not to loose cause off the plate or seepage. Tighten bolts should be re-pressurized and then put into operation. Use or storage of rubber joints, rubber joints in na?ve pressure (eg: means pressure test, etc.) before or after temporarily disabling enabled again. Avoid high temperature, ozone, oil and acid-base environment. With a sunny outdoor or wind pipe should build shade frame, non-exposure, rain, wind erosion. Joint appearance of non-painting and winding insulation materials. Because they are aging rubber products, should be checked and replaced. So compared to other general rubber: excellent antioxidant, ozone resistance, chloroprene rubber (CR) chloroprene monomer emulsion made from the polymer. This rubber molecules containing chlorine atoms. Non-flammable, Zhoukou rubber joints, after the fire self-extinguishing, oil, solvent, acid and anti-aging, and good air tightness; their physical and mechanical properties better than natural rubber, it can be used as general-purpose rubber, also It can be used as special rubber. The main drawback is the poor resistance to cold, flexible rubber joints, a large proportion of relatively high interest rates, use rubber joints, electrical insulation is not good, easy to stick roll machining, easy to scorch and easy to stick mold. In addition, raw rubber, poor stability, easy storage. Flexible rubber joints, Serco supply material (certified), Zhoukou rubber joints provided by Gongyi City Water Supply Materials Co. Serco.
