Products made of stainless steel have gradually entered industrial applications because of their long service life, not easy to rust, and green environmental protection. Stainless steel pipeline pumps are among the best. The stainless steel pipeline pump included in the stainless steel pipeline pump has been widely used in the market in recent years, and is loved by the majority of users because of its corrosion resistance, long service life, light weight, safety and hygiene. Moreover, the cost of construction is comparable to that of ordinary sewage pumps, because the price of its brown metal has continued to increase over the years, and the price is almost the same. The used stainless steel material is a green and environmentally friendly material, which can be recycled 100%, so in recent years, it has become a leader in stainless steel high temperature and corrosion resistant submersible pumps. Especially in recent years, countries in the food industry have put forward higher requirements. Stainless steel materials have gradually entered the stage of history because of their safety and hygiene. For rigid requirements, stainless steel pump products represented by stainless steel submersible pumps have begun to shine in food products. With the sharp increase in the market, the stainless steel pipeline pump industry is facing new technological innovations. Various companies are also competing to launch their own killers, constantly improve their R&D teams, and study related core production technologies, so as to improve their competitiveness in the market. Pump products represented by stainless steel pipeline pumps are leading the entire pump industry to move forward, and the raw material market driven by this, new stainless steel materials continue to come out. Various patented technologies and the continuous improvement of specifications are constantly driving the entire industry chain to a higher and more orderly goal. At the same time, it is also expected that pump products led by stainless steel sewage pumps will go abroad and become more popular in the world. Play the pride of Made in China on the big stage.

Now our industries are some modern industries, and pump products are an indispensable part of some enterprises. There are many kinds of pump products, and their functions are relatively comprehensive. Roots vacuum pump unit is a widely used equipment in industry. Next, let me introduce the misunderstandings that should be paid attention to when using roots vacuum pump unit. 1. The roots vacuum unit must be equipped with a front stage pump, and the roots pump cannot be used alone. 2. When selecting roots vacuum unit, we should pay attention to the sealing mode of vulnerable parts of roots pump. The mode of mechanical sealing can effectively improve the working efficiency of roots pump. If the sealing mode of roots pump is shaft sleeve sealing, the working efficiency will be greatly reduced. We need to pay special attention when selecting roots pump. 3. Roots vacuum machine is mostly used in Roots vacuum unit. Its function is to improve the pumping speed and the vacuum degree of the front stage pump. The roots pump shall be equipped with bypass valve in the configuration connected with the front stage pump, which can effectively protect the roots pump. If the pumping of the front stage pump is unstable or other factors lead to abnormal operation of the whole unit, the roots pump with bypass valve will protect the roots pump at this time, so as to prolong the service life of the whole vacuum unit. 4. If the vacuum degree of Roots vacuum pump is reduced during use, it is necessary to check whether the clearance between roots pump rotors has changed. If the rotor clearance of roots pump becomes larger, the roots pump needs to be replaced, because this kind of Roots vacuum machine does not make static and dynamic balance for Roots pump rotors during production and processing, Or it is sealed with shaft sleeve.

The most common use of Roots vacuum pump is sewage treatment. Roots vacuum pump manufacturers found that there will be some problems in the use of vacuum pumps of different brands. There are many reasons for the problem. What we need to do is how to avoid the problem of vacuum pump? After reading the following points, you will know how to deal with it! Methods to avoid roots vacuum pump failure Roots vacuum pump Start the pump Sudden liquid intrusion can damage the pump because of rapid cooling. The gas cannot reach the required temperature to evaporate the liquid. Additional steam cannot be pumped out in time because the front stage pump has been overloaded and the front stage pressure may rise to an excessively high level. To prevent this, it is necessary to install a receiver between the treatment room and the roots pump so that the liquid can be absorbed before entering the pump.

To prevent this, it is necessary to install a receiver between the treatment room and the roots pump so that the liquid can be absorbed before entering the pump. Dust accumulation In the process of generating particles or carrying dust - such as metallurgy or crystal drawing - it is necessary to install a dust filter at the air inlet of the pump to protect roots pump and downstream pump. The so-called debris protection net should be installed at the air inlet of roots pump. This prevents large solids and weld beads from being ejected from the welded joint due to improper cleaning when the system is used for the first time. In this case, it is recommended to use the accessories of the pump manufacturer, because the debris protection net is designed so that its free section can match the nominal diameter of the pump. This ensures that the pump speed will not be affected by unexpected conductivity loss. Extraction of critical gas When extracting valuable and high purity gases, such as helium 3 or helium 4, these gases must be avoided from contacting the surrounding air at all costs. At this time, the pump body is required to have high air tightness and low leakage rate in the area lower than 10-5 to 10-8 HPA L / s. Pfizer vacuum provides permanent magnet coupling for motor to replace ordinary shaft feed through parts. This makes the leakage on all shaft seal rings history. Enclosed motors can also be used. However, the operator must rely on the pump manufacturer for maintenance, because this kind of enclosed motor is specially developed for the pump. For magnetic coupling, cost-effective standard motors can be used. PUFA vacuum provides up to 250 m3 / H magnetic coupling for two-stage rotary vane vacuum pump and up to 12000 m3 / H magnetic coupling for Roots pump.

1. Lubricating water ring vacuum pump Since the vacuum pump and motor are integrated, only the motor bearings need to be lubricated. Under normal operating conditions (50Hz), motor bearings with class B insulation must be cleaned and added after about 8000 hours or a year. 2. Maintenance of water ring vacuum pump (1) Regularly check whether the bolts are loose, whether the air pipe leaks, whether the packing seal is fastened, whether the packing seal leaks, and whether the rotating parts have friction sound or other noise. If so, stop or repair or replace parts. (2) There shall be no sand or debris in the water. (3) If hard water is used as the working fluid, the water must be softened or the pump must be washed with solvent frequently. It is usually immersed in 10% oxalic acid for 30 minutes or in detergent used in industrial boilers for 30 minutes to remove calcium carbonate. (4) If the pump is not used for more than two weeks, drain the water in the pump, fill the suction port of the pump with 0.5L antirust agent or engine oil, and gently push the pump for less than 1s. (5) If the water ring vacuum pump is used where it may freeze at low temperature, antifreeze and corrosion-resistant working fluid, such as mineral oil, shall be used. Drain the water in the pump chamber after each use. (6) If the water ring vacuum pump does not work for a long time, drain the water in the pump and add anti rust liquid to protect the pump. water ring vacuum pump is used for reclaiming farmland from water
