Consistent speed gearbox 3.1 external enclosure materials and corrosion requirements and body principles. 3.2 Measures should be sealed box after box assembly can withstand immersion three meters of water conditions. Pneumatic valve opening and closing stopper 3.3 box on the adjustment nut should be in cabinets or in the outside box Z641F pneumatic valve manufacturers, but need special tools available jobs. 3.4 Drive structural design is reasonable, open and close valves can only drive shaft rotates Shandong valves, as not to traverse up and down Z641F pneumatic valve manufacturer, bite moderate transmission parts, does not produce open and close with a load when the separation skid. 3.5 Transmission box with the valve shaft seal leak can not be connected to the whole, otherwise the string should be a reliable anti-leakage measures. 3.6 cabinets no debris, grease should bite protection gear.
