1, magnetic column level gauge flange sealing surface is attached with dirt. Solution: Clean the sealing surface.
2. The sealing surface is damaged. Solution: Grind the sealing surface or replace the sealing surface.
Second, the valve stem transfer is not flexible:
1, the valve plug cover angle is too tight or the bearing wear. Solution: Adjust packing tightness or replace bearings.
2. There is debris or dust between the stem or the stem nut, and the stem or stem nut is damaged. Solution: Remove the cleaning stem and replace the stem or stem nut if damaged.
3, the opening and closing device fails. Solution: According to the device manual to check the failure after the maintenance of three, the central magnetic column level gauge flange leakage causes and solutions:
1. The flange bolts are not tightened or loosely tightened. Solution: Loosen the screw and tighten it evenly and symmetrically.
2, gasket damage or failure. Solution: Replace the gasket.
3, there is dirt between the flange sealing surface. Solution: Remove the cleaning flange.
Fourth, the stuffing box leakage:
1, loose packing or packing gland pressure bias. Solution: The packing gland should be pressed evenly.
2, magnetic column level gauge flange packing failure. Solution: Replace with new filler.
Chlorinated Polyethylene(CPE)
1. CPE is a kind of saturated rubber, which has excellent heat-resistant oxygen aging, ozone aging, acid and alkali resistance, and chemical resistance.
2. CPE has general oil resistance. Among them, it has excellent resistance to ASTM No. 1 oil and ASTM No. 2 oil, which is equivalent to NBR; and it has excellent resistance to ASTM No. 3 oil, which is better than CR and is equivalent to CSM.
3. CPE contains chlorine element, has excellent flame retardant performance, and has the characteristics of burning and dripping. It can be combined with antimony flame retardant, chlorinated paraffin, and Al(OH)3 in an appropriate ratio to obtain a flame retardant material with excellent flame retardancy and low cost.
4. CPE is non-toxic, does not contain heavy metals and PAHs, and it fully meets environmental protection requirements.
5. CPE has high filling performance and can be manufactured to meet various performance requirements. The processing performance of CPE is good, and the Mooney viscosity is available in a variety of grades between 50-100.
