Dry vacuum pump for high purity crystal vacuum processing

With the development of high-tech society, many manufacturing industries have strict requirements for the cleaning and environmental protection of vacuum pumps, and regulations to prevent the pollution of oil return and oil leakage to the environment. Therefore, the dry vacuum pump has a rapid development trend. Due to the late start, many of the company's customers' impression of dry vacuum pump only stays in a few claw type mechanical pumps and screw vacuum pumps.

The dry vacuum pump is suitable for the processing technology of high-purity air pump, with high vacuum value. Therefore, it can be integrated into extreme industrial and mining enterprises, and can solve the problem of steam body condensation, containing small particles. It has the characteristics of low energy consumption, high pump speed, long service life, maintenance free and no lubrication. Therefore, in the manufacturing industries of petrochemical, metallurgy, pharmaceutical, biotechnology, papermaking, electronic optical engineering, etc., low-tech vacuum equipment will be replaced in an all-round way.

Dry vacuum pump consists of motor stator, motor rotor, rotor, body, motor and other key components. The motor rotor with rotor blades is axially installed in the stator slot. When the motor rotor is running at high speed, the pump room is divided into four independent workshops by four axially driven rotor blades. Due to the centripetal effect, the rotor blade is close to the cylinder wall, which separates the motor stator from the inlet and outlet, circularly carries out variable capacitance, and makes the air inlet body discharge from the outlet. Then it goes beyond the vacuum.

Since there is no vacuum pump material (vacuum pump oil, water, etc.) in the dry vacuum pump, the steam body is not polluted by the vacuum pump material according to the dry vacuum pump. Therefore, the purchase of organic solvents is clean. The refrigeration part under the vacuum pump is transformed into the refrigeration part under the superheated steam, further improving the utilization rate of organic solvent raw materials, which is very beneficial to the refrigeration raw materials under the vacuum pump. According to the arrangement of this step, the discharged waste gas may contain industrial waste gas. On the other hand, the exhaust body of the pump greatly reduces the noise according to the shell side of the tubular condenser. Compared with gasoline pump, dry vacuum pump has low vacuum value and small air supply, but its volume is small, installation is convenient, maintenance is convenient, movement is convenient, no kitchen fume, no pollution to the environment, especially in the laboratory. All these are necessary equipment for the laboratory. Therefore, in the purchase of dry vacuum pump, first of all in the work of a clear vacuum value. If the requirements are high, and the mechanical pump selected must be higher than the required vacuum value, otherwise it can not meet the requirements of vacuum packaging, it can not meet the working standard.

Influence of water temperature on vacuum degree of water ring vacuum pump

Influence of water temperature on vacuum degree of water ring vacuum pump

After purchasing the water ring vacuum pump of our company for the first time, the user thinks that as long as the water is supplied by the water ring vacuum pump, the water temperature, pressure and other factors will not be considered. If the pump is used for a long time, it will bring adverse consequences to the water ring pump.

There are two reasons why the water temperature of water ring vacuum pump should not be too high:

Reason 1: because the water temperature is related to the suction capacity, the working fluid temperature is high, and the air volume will decrease.

Reason 2: working fluid in water ring vacuum pump mainly plays the role of sealing and cooling

The working liquid temperature of water ring vacuum pump will exceed 50 ℃ after working for n hours, so it is recommended to install a condenser to enhance the efficiency of the pump.

Because the water temperature is related to the suction capacity, the working fluid temperature is high, and the air volume will decrease. With the increase of temperature, the evaporation capacity also increases, occupying the discharge capacity of raw water ring vacuum pump, reducing the suction capacity, and prolonging the vacuumizing time. In addition, under the vacuum condition, the evaporation capacity of sealing liquid will also increase with the increase of temperature, and the larger the percentage of the discharge capacity of vacuum pump, the situation that cannot be vacuumized will occur. As for the data involved too much, the evaporation capacity of sealing liquid at various vacuum degrees is not the same as that at various temperatures. Only at a certain vacuum degree can we reflect the change of temperature and cause the change of evaporation capacity. Or vice versa. In use, it must be combined with temperature, vacuum two performance curves and pump performance curve superposition can be seen.

Cleaning method of liquid ring vacuum pump

Cleaning method of liquid ring vacuum pump

The cleaning of liquid ring vacuum pump is an important aspect of the maintenance of water ring pump, because it is hard to avoid some dirt in the pump cavity when the liquid ring vacuum pump is used for a long time. With the increase of time, the dirt covers the inside of the pump cavity, which has a great adverse impact on the performance of the pump!

In order to make the liquid ring vacuum pump last for a long time and keep its performance stable, daily maintenance work is inevitable. Only by doing a good job of cleaning it, it can work for us normally. The machine also needs to be taken care of, not only for the appearance of cleaning, but also for the interior to keep clean. Speaking of this, some people may think that it's OK to wash it with water. In fact, it's only necessary to wash it with water. This method is not enough, because there may be scale or other substances in the vacuum pump running for a long time. It is not enough to use only clean water for treatment. Clean the pump once.

How to clean the liquid ring vacuum pump correctly? Today, I'll teach you a simple and easy to learn method, which is to dilute nitric acid or other soluble substances, but do not use those with high purity, which will directly damage the internal components of the vacuum pump, put them in the container and wait for about an hour, and then wash them directly with water. If there is pressure, the effect will be achieved. Will be better, such cleaning steps is not very simple, only regular maintenance of the pump, in order to extend its life.

Of course, cleaning the liquid ring vacuum pump is only one aspect. In the daily maintenance, there are many components that need to be maintained by the user. For example, if any component is seriously worn, it must be replaced. Otherwise, it will directly affect the operation of the vacuum pump. If there is a problem in the pipeline, find out the cause of the leakage, and repair it in time. All these work should be checked every day during the use. Yes, as long as every detail is important, there will be no big problem with the vacuum pump.

Anticorrosion performance of water ring vacuum pump

Water ring vacuum pump is widely used with complete specifications and strong adaptability. Ordinary material pumps can meet most of the use requirements, but due to the different nature of materials, some working conditions have higher requirements on the anti-corrosion performance of pumps, so the pumps need to be made of anti-corrosion materials, let's understand this aspect:

According to the vacuum degree and corrosiveness of the pumped gas, the material configuration of water ring pump can be divided into three categories.

According to different anti-corrosion requirements, the flow passage parts of water ring pump can be made of stainless steel of corresponding brand, or the user can select materials according to needs. When the pump body is lined with rubber, the corrosion resistance of the pump body can be improved. When the flow passage parts are sprayed with special materials, the smooth spraying surface can avoid the retention of impurities and improve the hydraulic efficiency of the water ring pump.

The main parts of the water ring vacuum pump can meet the strict anti-corrosion requirements after anti-corrosion treatment or manufacturing with anti-corrosion materials. In addition to the above configurations, our company can also provide comprehensive and complete solutions according to the requirements of various working conditions of users.

Startup mode of Roots vacuum pump

Startup mode of Roots vacuum pump

Roots pump can not be started and used, which is basically known to the staff who often operate the equipment, but some novices always make this mistake. Therefore, today's editor will talk about the operation knowledge in this field, so as to avoid this kind of error when you first contact the equipment.

1. Roots pump can not be used alone. It usually needs to be equipped with a front stage pump, which is mainly used to improve the pumping speed, so it is also called a mechanical booster pump.

2. The roots pump can only be started when the previous pump reaches the allowable starting pressure. If it is started directly or fails to meet the air pressure requirements, the pump will be overloaded and the motor will be burned. Generally, the starting pressure is about 1.5 times of its differential pressure. For example, if the pressure difference of zj150 is 6000pa, the starting pressure is when the water ring pump pumps the system pressure to 90mbar.

3. If the front stage pump is a water ring pump, in order to prevent the circulating water of the water ring pump from flowing back into the oil tank, a check valve must be installed between the frontal water ring pump.

4. Roots pump can only work through the unit.

Therefore, before the roots pump is installed and ready for formal start-up, it must be checked first to ensure that all parts are installed correctly and auxiliary parts are complete, so as to carry out trial operation. After ensuring that there is no operation problem, it can be formally started for use, which is the correct and stable approach.
