Why is the impeller of 2BV water ring vacuum pump grinded?
We found that
many enterprises reflect that the impeller of 2BV water ring vacuum pump will be
damaged due to friction with the disc
The reasons are as follows:
① The
motor shaft moves too much in series
② Unreasonable assembly of impeller and
motor shaft
③ The extracted gas contains corrosion, and the motor shaft
sleeve is not corrosion-resistant
④ There is no annealing difficulty for the
disk, and it is deformed for a period of time

How to pump groundwater by steam ejector
The principle of pumping
groundwater by steam ejector is to use steam or other power medium to generate
strong power through the nozzle of the equipment to suck in the water at the low
pressure port, and then phase change occurs. After the water is completely mixed
in the mixing section of the equipment, it is discharged from the equipment.
Because the speed can change the pressure energy, the drainage pressure can be
increased to achieve the purpose of pumping water
Pay attention to the
following points in the design of the steam ejector: suction depth and discharge
pressure, steam consumption
As a user, steam is more expensive, and the less
it is, the more energy saving it will be
From our current experience,
generally let customers control in the vertical height within 7 meters,
sometimes in 8 meters
Then we consider that the outlet pressure is generally
5 kPa gauge pressure and the corresponding saturated water temperature is 102
℃
We calculate the amount of steam, in turn, push the outlet temperature of
water
If the customer requires the drainage pressure to be higher, we must
control the saturation temperature of water when we increase the amount of
steam, that is, the amount of steam can not be too much, resulting in water
vaporization
According to experience, if customers require high outlet
pressure, we usually reduce the height of vertical absorption (1m above the
liquid level), so as to increase the outlet pressure
There are many types of
working conditions in each group, and we optimize the design around the
principle of energy conservation

Analysis of reciprocating vacuum pump
Reciprocating vacuum pump is also
called piston vacuum pump, which is composed of crankshaft, piston, cylinder,
frame, intake and exhaust valve seat. The crankshaft is driven by the motor to
rotate, so that the piston moves up and down in the cylinder. The gas in and out
of the intake and exhaust valves will pump out a fixed volume of gas and make it
empty.
Reciprocating vacuum pump is the oldest vacuum pump, its advantage is
that the gas does not need to contact with other liquids, but it also has the
disadvantages of low efficiency, high noise, oil mist, and many vulnerable
parts.
In practical application, many fields have been replaced by liquid
ring vacuum pump. Compared with reciprocating vacuum pump, liquid ring vacuum
pump does not need vacuum pump oil for lubrication, and its structure is
relatively simple, and its maintenance cost is relatively low.

Carrying social responsibility and developing environmental protection water ring vacuum pump
With the development of social science, technology and
economy, environmental protection has become a problem that must be solved in
today's world
As the manufacturer of water ring vacuum pump, we have the
responsibility and initiative to research and develop environment-friendly water
ring vacuum pump
The environmental protection water ring vacuum pump faces
two major pollution problems
1、 Most manufacturers use water ring vacuum
pumps to directly discharge water or build large pools. However, the chemical
industry and other polluting industries will soon discharge water
pollution
2、 Noise pollution
For this reason, we have adopted the
combination method to develop hzkb environmental protection water ring vacuum
unit, which is composed of zkb water ring vacuum pump, waterway system, vacuum
system, cooling system, noise elimination facilities and control system, so as
to achieve 100% no leakage. According to different industries, different pump
liquid is used, and the use of circulating pump liquid is prolonged by adding
neutralizer. As for the noise pollution, we have installed a special noise
elimination system at the air inlet and exhaust port, especially for the
occasions where man and machine work together

Advantages of DC powered micro vacuum pump
The vacuum pump which uses
direct current to provide electric energy is called direct current oil-free
vacuum pump. DC vacuum pump has 5V, 12V, 24V power supply. The volume of 5V, 12V
vacuum pump or 24V DC vacuum pump is very small, so it is called micro vacuum
pump. The advantage of DC power supply is to avoid motor drive, so as to reduce
the power consumption. The power consumption is weak to MA (MA). The system in
the pump is integrated, and the weak current automatic control system is
adopted, so that the vacuum pump is completely free of manual control, achieving
more accurate and intelligent effect.
The micro DC vacuum pump mainly uses
the circular motion of the motor to make the diaphragm inside the pump do
reciprocating motion through the mechanical device, so as to compress and
stretch the air in the pump cavity with a fixed volume to form a vacuum
(negative pressure), which produces a pressure difference between the pump
suction port and the external atmospheric pressure. Under the effect of the
pressure difference, the gas is pressed (sucked) into the pump cavity, and then
discharged from the exhaust port.
Micro vacuum pump has high requirements for
air tightness, generally in 10 ^ - 7pam ^ 3 / S (10 minus 7 cubic meters per
second) can meet customer requirements for air tightness applications: such as
laboratory rare gas analysis, circulation, inspection, etc. The miniature vacuum
pump adopts brushless motor to adapt to alternating load, and its service life
can be up to thousands of hours (full load, 24-hour continuous test). If it is
used intermittently, its service life can be up to 5000-8000 hours.

Advantages and disadvantages of vacuum generator and vacuum pump
Vacuum generator is widely used in industrial automation, machinery, electronics, packaging, printing, plastic and robot fields. The following taiguan vacuum pump technical team engineers, to share the advantages and disadvantages of vacuum generator and vacuum pump. Hope to help you
The traditional purpose of vacuum generator is to use vacuum sucker to adsorb and transport all kinds of materials. It is especially suitable for adsorbing fragile, soft, thin non-ferrous, non-metallic materials or spherical objects. In this kind of application, a common feature is that the required suction volume is small, the vacuum degree is not high, and it works intermittently.
The vacuum pump is driven by the motor, and the vacuum is generated by the volume change. The commonly used types of vacuum pump in automation industry are rotary vane vacuum pump and piston vacuum pump. Rotary vane vacuum pump and piston vacuum pump are generally small, usually 1-to-1 or small system. Screw type vacuum pump, water ring type vacuum pump and claw type vacuum pump are generally used for system vacuum, even for the vacuum demand of the whole plant. The efficiency of vacuum pump is relatively high, and the power consumption is low, which is very energy-saving.

Application of industrial vacuum unit
Industrial vacuum cleaning has
become an indispensable equipment in the field of industrial production. It has
the function of both dry and wet, can absorb liquid and solid, can absorb all
kinds of metal, non-metal, oil, water and other particulate pollutants and
liquid, can absorb toxic and harmful gases, filter and purify air, clean the
environment. In the textile industry can improve the quality of products, in the
chemical industry can recycle some expensive catalyst, and as an environmental
protection equipment, industrial vacuum cleaner can effectively prevent some
occupational hazards, such as welder pneumoconiosis. The following taiguan
vacuum pump technical team engineers, to share with you the factory's detailed
explanation of industrial vacuum unit dust application. Hope to bring help to
you
Vacuum cleaning is to exhaust the air in the suction chamber by rotating
the pump blades to produce a certain degree of vacuum. The air pressure in the
suction chamber is less than that outside, resulting in the air pressure
difference. When the external air is inhaled, it carries the dust into the
suction bag inside the machine. The thinner the air in the suction chamber, the
higher the vacuum degree, the greater the pressure difference, and the easier
the cleaning, So the vacuum reflects the suction in the vacuum cleaner.
There
are two types of industrial vacuum cleaner, movable and fixed. Its working
principle is to use the motor to drive the high-pressure air pump (or the
all-in-one machine) to generate negative pressure in the limited volume, so as
to generate suction. After the medium is inhaled, it is filtered through the
filter bag or the filter barrel for secondary filtration. The ordinary type can
only absorb the dry medium with water content, The wet and dry type can absorb
the oil and water produced in the processing. After the installation of exhaust
pipe, it can be used to absorb the smoke and gas produced in the production
process.
Working principle of vacuum cleaning
1. The principle of dust
collection. Driven by the vacuum pump, the vacuum cleaner can discharge the air
from the air port at high speed, and at the same time, the air in the vacuum
part can be continuously supplied into the pump. It forms a high pressure
difference with the outside world. The dirt and liquid of the suction nozzle are
sucked into the dust collection part with the air and leaked through the leaker
to collect the dirt and liquid into the dust cylinder.
2. The original of the
vacuum cleaner. All vacuum cleaners are equipped with an assembled brush head
for cleaning floors and carpets. Suction vacuum cleaner will also be equipped
with a series of cleaning brush and suction nozzle for cleaning, filtering and
purification.
3. Round brush head: also smaller suction nozzle, can do 360 *
rotation.
4. Dustbrush: made of long soft bristles.
5. Hose: all suction
vacuum cleaners will be equipped with soft and hard hose to connect the cleaning
hose and accessories.
6. Flat suction nozzle: also known as gap suction
nozzle, is a slender, flat hard suction nozzle. It is especially suitable for
cleaning wall edge, radiant heater, corner and shallow and narrow place.
7.
Electric brush: cleaning head of internal vacuum cleaner, a special accessory of
hybrid vacuum cleaner.
