1、RVVAir-operated Diaphragm PumpOperating Instructions1 1 1 1OverviewOverviewOverviewOverviewThe RVV series air-operated diaphragm pump of our company is a latest model of fluid transportationequipment, which is currently one of the most innovative pumps in china. Using compressed air as the powersour
2、ce, it can pump various fluids drastically, whether corrosive, volatile, flammable, poisonous liquid orfluids with particles and high viscosity.Our diaphragm pumps have totally six specifications. The sizes for import/export are 1/4“, 1/2“, 3/4“, 1“, 1.5“,2“, 3“ and 4“. The components which contact
3、with the fluids are usually made of aluminum alloy, nodular castiron, polypropylene, stainless steel. Depend on the varied applications, and the materials of diaphragm canbe styrene rubber, neoprene, polythene, polyether rubber, fluorine rubber, Teflon and PVDF, so that it canmeet the requirements o
4、f different fluid mediums. 2. 2. 2. 2.WorkingWorkingWorkingWorking principle:principle:principle:principle:The RVV series air-operated diaphragm pumps are based on the following working principle: two flexiblediaphragms are fitted into two symmetrical chambers of the diaphragm pump severally and con
5、nected as awhole part by a link rod. The compressed air enters the central body through the in-suck terminal and impelsthe diaphragms in two chambers to drive consequently the link rod into move synchronously.At the sametime, the air in the other chamber is expelled from the back side of the diaphra
6、gm. When piston reaches theend of the stroke, the air-distributing valve guide compressed air into the other chamber automatically anddrive diaphragm pump to rotate reversely, so that the synchronous reciprocating movement is realized.RVV series air-operated diaphragm pumps are distinguished obvious
7、ly by the structure of the air-distributingvalve from other diaphragm pumps. This air-distributing valve replaces the traditional O-ring and cylindricalstructure with a three-direction pilot-operated structure, eliminating consequently the dead center of valveand shutdown phenomenon of pumps. It pro
8、vides an accurate and reliable reversing signal to avoiddowntime and realize faster reversing, so that pumps have greater flow and the transportation is more stable,with lower pulse.RVV series air-operated diaphragm pump has a simple designs and highly reliable reversing valve. It canensure non-stop
9、 operation and therefore reduces the expensive downtime cost.All components of the valvecan be replaced without disassemble.Aluminum parts have been specially processed, so can resist thecorrosion resulted from unclean air. The slide block made of plastic material is robust and anti-tampered, andnee
