◆ The working principle of Multipurpose
Pneumatic Diaphragm Pump
1 The compressed air as its power.
2 It is a volumetric pump that the repeat transfiguration
of the diaphragm makes the change of volume, and
the working principle is same as piston pump. The
characteristics of the pneumatic diaphragm are as
followings:
⑴no heat quantity generation: taking compressed
air as its power, and the exhaust is a expansion
and heat absorption process, the temperature is
decreased when working and no harmful gas exhaust.
⑵no generating electric spark: it doesn’t use electricity
as its power, against electrostatic spark.
⑶the liquid which contains grain can pass: it is
a volumetric operation and inlet is a ball valve.
⑷low shear stress: the same operation of absorbing
and discharging, the smallest agitation, be suitable
to conveying unsteady material.
⑸the flow can be adjusted, can install baffler in
outlet to adjust flow.
⑹ the function of self absorption.
⑺no generating danger when dry running.
⑻it can be used as diving working.
⑼the comprehensive conveying range from low-viscosity
to high-viscosity material or from corrosive to
viscous material.
⑽no complex control system, cable and fuse.
⑾small volume, light weight and be easy to move.
⑿no need using lubrication to maintain, not polluting
working environment.
⒀continuously keeping high efficiency, can’t be
affected by the abrasion.
⒁making the best of energy, once closing outlet,
the pump stop working, on the contrary, it automatically
operates when the outlet is opened.
⒂avoiding leakage when maintain it, no dead point.
