◆ OCCASION ◆ |
◆ The Applicable Occasion of
Multipurpose Pneumatic Diaphragm Pump
Owing to the above characteristics, the pneumatic
diaphragm pump gradually has emerged into other
pumps markets since it is developed in the world,
and has occupied a part of them, for example, it
has a leading position in ceramics, and broa dens
its market share in the industries of environmental
protection, wastewater treatment, construction,
pollution discharge and fine chemical industry.
Its advantages include: 1、due to using air as its
power, it can automatically adjust its flow according
to the change of back pressure, and be applicable
to high-viscosity liquid. Comparing with the centrifugal
pump, the operating point is set up on the basis
of water. If the liquid viscosity is high, it will
need auxiliary reducer or variable frequency speed
controller, thus must increase cost and the same
as the gear pump.2、the usage of pneumatic diaphragm
pump is credible and needs low cost under the flammable
circumstances such as the conveyance of fuel, powder
and dynamite. There have three reasons. First, there
hasn’t spark generation after earth connection.
Second, it does not produce heat quantity. Last,
the liquid won’t have high temperature because the
agitation of the pump is small. 3、when the condition
of building site is bad such as industrial and mineral
wastewater discharge, it has many sewage impurity
and the element is complex. As a result, the pipeline
is apt to block, and the load of the motor pump
is so high that the electric machine generates heat
quantity and is liable to damage. But these grains
can be passed in diaphragm pump and the flow can
be adjusted, and when the pipe is blocked, it automatically
stop operation till it becomes unobstructed. 4、besides,
the volume of the diaphragm pump is small and is
easy to move, having small floor space and simple
and economical installation. It can be used as the
pump for m obile
material. 5、in the process of handling with dangerous
and corrosive material, it can completely
separate material from external circumstance. 6、or
some raw materials which have no grain and pollution.
7 it can be used to conveying some liquid which
chemical property is unstable, for example, photosensitive
material, flocculant and etc. It is because that
the shear stress of the diaphragm pump is low, having
small physical effect to material.
