Water ring vacuum pump is the vacuum pump used to pump underground methane. The product has high negative pressure and small flow rate, and is suitable for use in mines with low discharge and high negative pressure. In addition, it has high safety performance, so it is widely used by people. Let as the water ring vacuum pump manufacturers to introduce the relevant products.
Water ring vacuum pump of working principle
Water ring pump work wheel in the pump body rotation formed a water ring and studio. The water ring and the work wheel form a crescent space. The volume of the right half of the crescent increases from small to large, forming the suction chamber. The volume of the left half crescent is reduced from large to small, forming the compression process (equivalent to the exhaust chamber). The aspirated gas enters the suction chamber through the inlet pipe and inlet port. The rotor rotates further, so that the gas is compressed and discharged through the exhaust port and exhaust pipe. The discharged gas and water droplets enter the water tank through the exhaust pipe. At this time, the gas is separated from the water. The gas is discharged into the atmosphere through the pipe.
In the country, each large and small production or assembly of water ring vacuum pump manufacturers are very many, more water ring vacuum pump factory or dealer. Water ring vacuum pump manufacturers are very many, the quality is uneven, water ring vacuum pump price is also several hundred to several thousand pieces, even tens of thousands, hundreds of thousands of different. The same type of water ring vacuum pump of the same material sold by different “manufacturers” at very different prices, these existing conditions, resulting in market chaos. Of course, the low price, also make “vacuum pump manufacturers product quality and service at a discount. Make the user at a loss, do not know the water ring vacuum pump which good? How to choose?
Therefore, how to choose and how to choose has become a difficult problem for most people. Here is my personal opinion, I hope to help you.
Water ring vacuum pump manufacturers to buy notes:
1. Check whether the business license, tax registration and other certificates of the production and sales units are complete and whether they belong to the production enterprises and the enterprise life.
2. The qualifications of the water ring vacuum pump supplier, such as safe labor production level, high-tech enterprise, measurement level certificate, IS certification, reputation certificate, patent certificate, etc., can reflect the comprehensive ability of the supplier to a certain extent. Capable, regular production enterprises are generally guaranteed quality.
3. Know the situation of water ring vacuum pump used by other manufacturers in the industry, and know the manufacturer of water ring vacuum pump. Every water ring vacuum pump enterprise has its own unique understanding and focus in a certain field.
4. See the supply capacity of water ring vacuum pump manufacturers. If the supply capacity of the manufacturer is sufficient, then the strength level of the manufacturer is very good.
5. Whether the production technology and technology of the manufacturer are advanced or not. Advanced production technology manufacturing water ring vacuum pump, its product quality will be better.
6. Product price and after-sales service, etc. The manufacturer that has good faith, have public praise won’t overcharge, not only the price is fair, its after sale service also can be very thoughtful.
The above 6 points can help you choose a good manufacturer, to meet the above points can guarantee the manufacturer’s service standards, production mode and quality requirements.
In addition, we can pay more attention to the following points.
For example: water ring vacuum pump oil cleanliness; Oxidation stability of water ring vacuum pump oil; Heat resistance and stability of water ring vacuum pump oil; Demulsification of water ring vacuum pump oil; Vacuum pump oil foam resistance.
