Judging the working condition of exhaust end of miniature pump
The above problem is to discuss the suction end resistance of the
pump. According to these conditions, the range of selection has
been reduced, but the problem of exhaust end resistance must be
considered. In this way, the optional range can be determined.
In practical application, the exhaust condition of the micro vacuum
pump is different: one is that the exhaust is very smooth and goes
straight to the atmosphere; the other is the high exhaust
resistance, such as valves, small bends, and large damping sensors
on the exhaust pipe road, Non-specific silencers, exhaust below
liquid level, gas to airtight or semi-closed containers, etc. In
modern design and manufacture, the micro vacuum pump with different
exhaust conditions is treated differently. " The parameter of the
maximum resistance Por value "is to calibrate the exhaust capacity
of the pump, so we can use strict technical means to determine
whether the type selection is appropriate or not."
According to the above steps, we have been able to determine the
selection range of the micro pump. The allowance should be left for
the selection of the attention parameters, especially the flow
parameters. After the pump is connected to the gas path system, the
pressure loss will be caused by the pipeline, valve and other gas
elements, so the flow rate is smaller than the nominal flow rate of
the pump, and some problems related to the selection of the pump
are listed below, which are considered according to the application
Working principle: the rotary motion of the motor turn into the
swing of connecting rod which makes the diaphragm up and down
motion. In the process of the downward movement of the diaphragm,
pump cavity will suck medium through the inlet valve; Upward
movement of the diaphragm, pump cavity press out media through the
outlet valve. Mechanical transmission parts and pump cavity is
isolated by diaphragm. Diaphragm pump does not need oil for
auxiliary lubricating, in the process of transmission, extraction
and compression of medium.
mini diaphragm air pump's parameter and features
1. Small and powerful
2. Extreme chemical resistance
3. Brush and brush-less direct current motor for selection
4. Dry running, durable and maintenance free
5. Self-priming and excellent for pressure
6. Low noise, longer endurance lifetime than other normal membrane
Our company offers multiple component configurations allowing
piston pump to be used for either vacuum operation, pressure
operation, or alternating vacuum and pressure operations.The
innovative, compact design incorporates leading edge technologies
that allow it to operate harder, quieter and longer, reliable,
Its flow can deliver up to 2 L/min and 18L/M.
Usually our pump has 4 kinds of voltage:6V, 9V,12V and 24V .
When you choose pump, you can tell me the pump's voltage you need.
We can do it for you.
You can choose pump according to our model.
In addition,it can be mounted in any position.
mini diaphragm air pump's details show
Unlabeled tolerance is ± 0.1mm.
Outlet:OD 6.5mm, silicone hose suggestion:ID 5mm
Materials:pump body: PC/PPS, diaphragm: EPDM
Because we use imported ball bearing,the pump’s performance is
stable and high.
The membrane is made by EPDM and pump's body is made by special
PC/PPS which make pump well endurance and strong chemical
