I. GENERAL DESCRIPTIONS :
|
|
1.
|
The
pneumatic double diaphragms pump utilizes the air-driven principle with
high
safety measurement. It does not
generate any sparks and resist to explosions.
|
|
2.
|
The
pneumatic valve is adopted to meet ISO 5599/1 specifications and no
lubrication oil required after long time operating.
|
|
3.
|
Wide range of applications:
PU. UV. polylaquer. Inks, and etc.
|
|
4.
|
Compact, light weight,
portable, simple operations and easy to
change paints. Applicable to
different types of storage tanks.
|
|
|
|
|
II. SPECIFICATIONS:
|
|
|
Fluid
rate: 45 liter/min
|
|
|
Pressure
ratio: 1:1
|
|
|
Used air pressure: 1.5~3kg/cm2
|
|
|
Max.pressure: 7kg/cm2
|
|
|
|
|
III. INSTALATIONS:
|
|
1.
|
Adopt
foot stand 53 gallon tank covered with wall mounted & mobile car.
|
|
2.
|
The
air inlet must be installed with the air cleaner to prevent dirt from
entering into the air pilot valve and damaging components.
|
|
3.
|
Employ single pipe and prevent
dead angles in order to maintain smooth transporting.
|
|
|
|
|
IV. HOW TO OPERATE :
|
|
1.
|
Adjust
the operating pressure accordingly to the transporting range.
|
|
2.
|
The
operating pressure cannot be less than 1.5kg/cm2. If there is a shortage of air
pressure, the pump will not be operated smoothly and it can possibly
cause pump to be clogged.
|
|
3.
|
Everyday, the piping system
must be cleaned after the work.
Especially,
when the pump is used for heavy viscosity painting. It is highly recommended that
pumps should be cleaned completely for clog-free operation afterward.
|
|
|
|
|
V. TROUBLE SHOOTING :
|
|
1.
|
In
the case of disassembling the pump for maintenance, shut the air inlet or
release it and the paint outlet
must to be released also.
|
|
2.
|
|
|
Do
not operate pumps under the following conditions:
1.
Pumps are clogged.
2.
Diaphragms are damaged.
|
|
|
3.
|
|
Possible
causes when there is no suction force:
|
|
|
·
The ball seat is clogged at suction orifice.
·
The suction pipe is damaged, which can reduce paint
spraying smoothness.
·
The pump has not been operated for a long time and
the paint becomes hardened.
