Vacuum Pumps for Installation Requirements

The vacuum pump needs to be installed correctly before it runs. The location of the installation is more important. What kind of environment is it installed in? See the following details.

1. Vacuum pumps should be installed in dry, well ventilated and clean places.

2. It should be installed in a strong place on the ground. There should be sufficient room around it for inspection, maintenance and maintenance.

3. The foundation level should be maintained under the base of the vacuum pump. It is suggested to install cushion rubber or bolt at the four corners of the base to ensure the smooth operation and low vibration of the vacuum pump.

The installation position of the vacuum pump is determined, which is convenient for later operation and avoids the occurrence of faults in use. I hope today's knowledge will help you.

2BV Water Ring Vacuum Pump of cavitation Phenomenon

When the vaporization pressure of 2BV water ring vacuum pump liquid is reduced to the vaporization pressure at a certain temperature, the liquid will produce bubbles. This phenomenon of bubble formation is called cavitation. When the bubbles generated by cavitation flow to the high pressure, their volume decreases to collapse. The phenomenon that bubbles disappear in liquids due to pressure rise is called cavitation collapse. This is also the problem of 2BV water ring vacuum pump in use. How to deal with this problem? The measures to prevent cavitation are as follows:

1. Reduce the height of geometric suction (or increase the height of geometric backfilling).

2. To reduce the inhalation loss hc, we can try to increase the pipe diameter and minimize the pipe length, elbows and accessories.

3. Prevent long-term operation under large flow.

4. Under the same speed and flow rate, the double suction pump is adopted, because the inlet flow rate is reduced and the cavitation of 2BV water ring vacuum pump is not easy to occur.

5. When cavitation occurs in the pump, the flow rate should be reduced or the speed should be reduced.

6. For pumps operating under harsh conditions, anti-cavitation materials can be used to avoid cavitation damage.

If cavitation occurs in the use of 2BV water ring vacuum pump, it will be destroyed, noise and vibration will also occur and the performance of the pump will be reduced. Seriously, the liquid in the pump will be interrupted and the pump will not work properly. Therefore, it is very important to prevent cavitation in 2BV water ring vacuum pump.

liquid ring vacuum pump of price

The liquid ring vacuum pump, know its friends should know that its use is very wide, then its price is affected by what factors? Next, let's follow us to understand the factors that affect the price of liquid ring vacuum pump.

1. Regionality. At present, most domestic products are facing the dilemma of having accessories without technology and without accessories. Because of the regional problems of raw materials, the prices of liquid ring vacuum pumps are uneven.

2. The material of the pump body can be divided into nodular cast iron and grey cast iron. Nodular graphite is obtained by spheroidizing and inoculation treatment, which effectively improves the mechanical properties of cast iron, especially the plasticity and toughness, thus obtaining higher strength than carbon steel. Ductile iron is a kind of high strength cast iron material developed in the 1950s. Its comprehensive properties are close to steel. It is precisely because of its excellent properties that it has been successfully used to cast some parts with complex stress, high strength, toughness and wear resistance.

3. Technical content of liquid ring vacuum pump. As we all know, the maturity of technology, the stability, reliability and life of products manufactured by high-standard processing and production equipment have an impact.

4. Quality of accessories. The liquid ring vacuum pump is mainly composed of several parts, such as filter, marble, exhaust hood, etc. The quality of these parts directly affects its price.

vacuum pump of workflow

Vacuum pump is an integral structure - a single-stage coaxial pump. The shaft seal adopts mechanical seal, which has the characteristics of simple structure, simple installation, oil-free, safe and reliable. Understanding vacuum pumps not only requires a general understanding of their performance, but also involves in the working process of vacuum pumps, compressors and gas-water separators. Let's take a look at its workflow.

The gas enters the Nasim vacuum pump through the pipeline through the valve, then enters the gas-water separator through the exhaust pipe, and discharges through the exhaust pipe of the gas-water separator. When used as a compressor, the gas-water mixture discharged by the compressor is separated in the gas-water separator, and the gas is conveyed to the system requiring compressed gas through the valve. The working water in the vacuum pump is discharged from the gas-water separator without cooling to the vacuum pump for reuse. The rest of the working water is supplemented by the water supply pipe. The size of the water supply is adjusted by the valve on the water supply pipe.

The difference between gas suction and pressure delivery systems is only that the internal structure of the gas-water separator is different. When sucking gas, the suction port pressure is lower than atmospheric pressure, while the exhaust port pressure is equal to atmospheric pressure, and the gas-water separator has overflow pipe; when pressurizing gas, the suction port is atmospheric pressure (or vacuum state), and the exhaust port pressure is higher than one atmospheric pressure. In order to ensure the transmission gas pressure, the water level of the gas-water separator is controlled by the overflow switch.

Above is the main working process of vacuum pump. Understanding this process can help us to effectively grasp every link of production in the production process, and also detect the occurrence of faults and errors in the production process in time.

Stainless steel vacuum pump

Stainless steel vacuum pump has corrosion resistance, but we still need to pay attention to the following points when using, so as to extend its service life:

1. Stainless steel vacuum pump should be operated in high efficiency area, that is, in critical vacuum or critical exhaust pressure area.

2. Avoid operating near vacuum or exhaust pressure. Operating in this area, not only the efficiency is very low, but also the work is very unstable, easy to produce vibration and noise.

3. For stainless steel vacuum pumps with high vacuum, although stainless steel is used, cavitation often occurs in the operation of the pumps in this area. The obvious sign of this phenomenon is that there is noise and vibration in the pumps.

4. Cavitation will cause damage to pump body, impeller and other parts, so that the pump can not work.

Above is our introduction today, so stainless steel vacuum pump is good, but we must avoid these, in order to better use, I hope Xiaobian simple introduction can bring you benefits.

Liquid Ring Vacuum Pump Purchase

The type and type of liquid ring vacuum pump are various. Choosing a suitable equipment to meet the requirements of working indicators plays a vital role in the efficiency of production and operation safety. The following section summarizes several methods for you to choose and purchase:

1. First of all, we should fully understand the composition of the exhausted gas. If the gas contains no condensable vapor, particulate dust, corrosiveness, explosion and so on; if the extracted gas is explosive, it should be equipped with explosion-proof motor, because the whole working process of the equipment is isothermal.

2. Understand the impact of the oil vapor discharged from the equipment on the environment. If the environment is not allowed to be polluted, choose oil-free equipment or discharge the oil vapor outdoors.

3. The equipment should be assembled correctly. Because each kind of equipment has selective pumping, so sometimes the selection of a pump can not meet the requirements of pumping, several pumps need to be combined to complement each other in order to meet the requirements of pumping.

4. If there are many equipments working at the same time, the circulating liquid should be cooled, otherwise the vacuum degree will be affected. The cooling device can be equipped with cooling tower, and booster pump should be equipped to pressurize the pipeline.

5. Whether the vibration caused by the working equipment has an impact on the process and environment, if the environment is not allowed, the vibration-free pump should be selected or vibration-reducing measures should be taken.

6. Under its working pressure, the equipment should be able to discharge all the gas produced in the process of vacuum equipment.

Special attention should also be paid to considering the price, operation and maintenance costs of the equipment according to the actual situation. I hope that the method of selecting and purchasing the liquid ring vacuum pump described above can really help you, apply it to practice and bring real benefits to production operations.
