In practical use, in fact, most of them are laymen, but need to use more than one object in the work. Many customers say that they do not know how to buy correctly when the pump is selected. The supplier of the liquid ring vacuum pump answers many kinds of doubts for you.
As a supplier of Syrian liquid ring vacuum pumps, Xiaobian would like to let you know the following:
1. Make the type and performance of the selected pump meet the requirements of the process parameters such as device flow, head, pressure, temperature, cavitation flow and suction.
2. It must be suitable for the requirements of medium characteristics.
(1) for pumps that transport flammable, explosive or harmful or valuable media, shaft seals are required to be stable or leak-free pumps are used.
(2) To pump the corrosive medium, it is required that the convection part adopt the corrosion-resistant material.
(3) for the pump which conveys the solid particle medium, the convective parts are not easy to grind, and the shaft seal is washed with clean liquid when needed.
3. The mechanical stability is high, the noise is low, and the vibration is small.
4. The overall cost of equipment, operating, maintenance and management costs should be taken into account in the economy.
5. The liquid ring vacuum pump has the advantages of high rotating speed, small volume, light weight, high efficiency, large flow rate, simple structure, no pulsation of infusion, stable performance, easy operation and maintenance, and so on.
EVP is not only the supplier of liquid ring vacuum pump, but also the supplier of screw air compressor, which provides you with good quality equipment, long-term maintenance scheme and reduces the occurrence of failure.
Liquid ring vacuum pump of quotation
The liquid ring vacuum pump adopts the single stage structure of coaxial action of the pump, which has the advantages of simple structure, convenient maintenance, reliable operation, high efficiency and energy saving, and can adapt to the bad working conditions such as large displacement, load impact fluctuation and so on.
The new type of liquid-ring vacuum pump is different from that of the internal part due to its different material, and its price is very different. The quotation of the liquid ring vacuum pump is generally determined by its material and model.
First, the quotation of liquid ring vacuum pump is affected by the flow power of vacuum pump.
The liquid-ring vacuum pump is different from the power of each model, for example, the liquid-ring vacuum pump of the 2BV2060 and the 2BV5121 model, whose quotation is influenced by different power and different flow, and the latter is higher than the former.
Second, the quotation of liquid ring vacuum pump is also affected by material.
The liquid ring vacuum pump made of stainless steel is higher than the price of the liquid ring vacuum pump made of common cast iron. The liquid-ring vacuum pump made of stainless steel is mainly used for easy-to-rust and rust-prone working conditions.
They are also divided into internal parts stainless steel, part stainless steel and integral stainless steel. The inner part is mainly liquid wheel stainless steel. The part stainless steel is mainly of the pump head stainless steel, and the quotation of the liquid ring vacuum pump of the whole stainless steel is relatively high.
Third, the quotation of liquid ring vacuum pump is affected by explosion-proof motor.
Explosion-proof motor is a kind of motor which can be used in flammable and explosive places. Explosion-proof motor is mainly used in coal mine, petroleum and natural gas, petrochemical industry and chemical industry.
In addition, in textile, metallurgy, urban gas, transportation, grain and oil processing, paper, medicine and other departments are also widely used. Explosion-proof motor as the main power equipment, usually used to drive pumps, fans, compressors and other transmission machinery, etc.
Under the condition of flammability and explosion, the liquid ring vacuum pump must be equipped with explosion-proof motor, and the ordinary motor can not ensure the safe operation of the liquid ring vacuum pump under such bad working conditions. Therefore, the quotation of liquid ring vacuum pump with explosion-proof motor is also higher than that of liquid ring vacuum pump with ordinary explosion-proof motor.
Depending on the customer’s needs and the customer’s environment and process, we can match different types of liquid-ring vacuum pumps with different types of materials. The quoted price of the liquid-ring vacuum pump is high, but the customer must be equipped with the appropriate model and material in order to guarantee its normal use.
