In order to let
you better choose and use the vacuum pump, we summarize the following points for
attention, so that you can choose the right product. According to the actual
use, we should pay attention to these:
1. Whether the vibration of small
vacuum pump has influence on the process and environment. If the process is not
supported, the pump without vibration should be selected or a series of anti
vibration measures should be taken.
2. Understand the composition of the
extracted gas, whether there are particles, dust and corrosivity in the gas.
When choosing the vacuum pump, we need to know the gas composition, and we need
to choose the corresponding pump for the gas to be pumped. If the gas contains
steam, particles and corrosive gas, it is necessary to consider the installation
of auxiliary equipment on the inlet pipeline of the pump.
3. Under its
working pressure, the small vacuum pump can discharge all the gas produced in
the process of vacuum equipment.
4. Correct combination of vacuum pump.
Sometimes one kind of pump can't meet the requirement of pumping. Because vacuum
pump has selective pumping, it needs several pump combinations to complement
each other to meet the requirement of pumping. If the titanium sublimation pump
has a high pumping speed for hydrogen, but it can't pump helium, and the triode
sputtering ion pump (or the bipolar asymmetric cathode sputtering ion pump) has
a certain pumping speed for argon, the combination of the two will make the
vacuum device get the corresponding vacuum degree.
5. Requirements of small
vacuum equipment for oil pollution. If the equipment clearly requires no oil,
all kinds of no oil pump should be selected. If the requirements are not strict,
oil pump can be selected, plus some anti oil pollution measures.
6. Choose
the working point of small vacuum pump correctly. Each pump has a certain
working pressure range. Therefore, the working point of the pump should be
selected in this range, rather than long-term operation at 25 ~ 30mmhg.
7.
How does the oil vapor discharged from the small vacuum pump affect the
environment. If the environment does not allow pollution, you can choose a small
oil-free vacuum pump, or the oil vapor to the outside.
8. The working
pressure of small vacuum pump should meet the limit vacuum and working pressure
requirements of vacuum equipment. For example: a vacuum drying process requires
a working vacuum of 10mmhg, and the limit vacuum of the selected vacuum pump
should be at least 2mmhg, preferably 1mmhg. Generally, the limit vacuum of pump
is half to one order of magnitude higher than that of vacuum equipment.
In
addition:
At present, there are few domestic manufacturers producing oil-free
vacuum pumps. Basically, they can only produce rotary vane vacuum pump products
that must be added with vacuum oil. The market is basically imported oil-free
vacuum pump products. Taiguan's oil-free rotary vane vacuum pump is manufactured
by using Taiwan's oil-free rotary vane vacuum pump technology. It has the
advantages of simple structure, easy operation, convenient maintenance, low cost
and low cost It will not pollute the environment. The two series oil-free vacuum
pumps are durable. Good performance, is a vacuum, compression, dual-purpose
vacuum pump, is a very wide range of applications to obtain the basic vacuum
equipment.
