◆ The Summarization of
Multipurpose Pneumatic Diaphragm Pump
The QBY pneumatic diaphragm pump produced by our
company is a latest conveying machine, and has
passed the product quality test of mechanical
facilities of irrigation and drainage of China
mechanical industry. The product is the latest
type of pump in same domestic industries at
present, and adopts compressed air as its power
source, having the characteristics of excellent
pressure and flow automatic adjustment. It can be
optionally set pressure under the range of
operating pressure, and it won’t damage even if
output port is blocked and flow is zero, be
extensively used in various
liquid conveyance and as charging pump of pressure
filter.The gas and liquid part adopt modularized
design, and each part has different materials, can
choose combination to fit the different liquid
conveyance. It can be applied to convey all kinds
of high content and strong abrasion grain
material,its diameter is big, be used to convey
various strong acid, strong base and strong
corrosion medium. It adopts compressed air as its
power source, and gas and liquid completely
separate. With the usage of sealing structure,
there have no leakage and lubrication problems.
Not generating electrical spark when operation,
specially applied in the unexplosive occasion. Its
working principle is that air pressure difference
promotes double diaphragm operation through
alternative effect, forming convection alternative
effect, thereby conveying liquid by one-way valve
of charging and discharging portal. Once
compressed air drive pipe has pressure, it begins
to operate and to maintain certain pipeline
pressure till it reaches the set point.
