FPZ corrosion-resistant plastic self-priming pump for chemical, pharmaceutical, food, smelting, environmental protection, sewage treatment and other fields transport acidic, alkaline and corrosion-resistant chemical liquids and other industries. Since FPZ anti-corrosion plastic self-priming pump uses such a wide range, then we all know that it should pay attention to the installation of what matters? If you do not know, now we introduce FPZ anti-corrosion plastic self-priming installation should pay attention to matters. FPZ corrosion-resistant plastic self-priming pump installation notes 1, FPZ plastic corrosion-resistant self-priming pump before installation (due to long-distance transport) must carefully check the various parts of the fastener is loose, if loose should re-tighten the machine shaft Concentricity, if any deviation must be corrected. 2, the installation of pipe can not be directly supported on the import and export of the pump flange, you must set up another support point to prevent deformation damage. Import pipelines should try their best to reduce the number of pipelines, hydraulic loss of roads, 90. No more than two elbows, suction tube shall not leak, otherwise it will affect the vacuum pumping time or liquid spit and fluid flow, lack of head. 3, the first time using the boot before opening the infusion cap, the fluid filled FPZ, PVZ anti-corrosion self-priming pump body, and the fluid cap tightening, shall not leak, non-destructive run-off and reverse rotation. 4, there is a bracket bearing pump, before use must be filled with cooling oil to the mirror half, or to burn out the bearings, and regular replacement of oil. 5, the fluid can not have sediment or longer soft fiber, to prevent plugging damaged impeller and mechanical seal. 6, FPZ plastic corrosion-resistant self-priming pump outlet should be installed valves, shut down the valve first and then shut down, and then open the valve.

Neglecting elevator door equipment jeopardizes riding public safety and increases owner liability. Modernizing elevator door equipment is important in making an older elevator system more reliable, safe, code compliant, efficient, and provides a more marketable appearance. This is particularly true with door operators. Door operators undergo tremendous wear and tear in daily operation. Each time the elevator stops, the door operators are activated at least two times, more frequently if occupants manually hold the doors open. Some elevator maintenance companies report that nearly 75 percent of their service calls are for malfunctioning door operators
