Market and purchase of water ring vacuum pump
Nowadays, there are many brands and types of vacuum pumps sold on the market, especially rotary vane vacuum pumps, Roots vacuum pumps andWater ring vacuum pumpThe sales volume in the market is relatively high, and the market reputation is generally good. These different types of vacuum pump products have different performance characteristics, among whichWater ring vacuum pumpIn the market application more, better response.
according to our understanding,Water ring vacuum pumpCan be specifically divided into single-stage single-actingWater ring vacuum pumpSingle-stage double-acting water ring vacuum and two-stageWater ring vacuum pumpAnd atmospheric water ring vacuum pump and other types. These different types of vacuum pumps have obvious differences in structure, in which single-stage single-actingWater ring vacuum pumpand single-stage double-actingWater ring vacuum pumpThere is only one impeller, its limit vacuum is relatively high, but relatively speaking, the pumping speed and efficiency are low. And double-levelWater ring vacuum pumpand atmosphereWater ring vacuum pumpThe limit vacuum is higher and the pumping speed is higher.
Although saidWater ring vacuum pumpThe structure and characteristics are different, and the difference between its function and the overall scope of use is not particularly large. The vast majorityWater ring vacuum pumpIt can be used in many fields, such as petrochemical industry, electric power industry, paper industry, plastic manufacturing industry, equipment manufacturing industry, environmental protection industry, food and beverage industry, packaging industry, metallurgical industry, shipping industry, wood processing industry and sugar industry.
Water ring vacuum pumpThe purchase of has always been a hot topic for users. Suitable equipment can not only play a full role in production, but also improve production efficiency faster. What the editor wants to share with you is its purchase. What aspects should be considered.
1, first of all, should be clear about the arrangement of the device, terrain, water level conditions and operation, economic plan comparison and other aspects of the actual situation.
2. Consider selecting the specific model of the pump. After selecting the series of pumps, the two main performance parameters of the head after 0.05 a 0.1 margin can be amplified according to the flow limit, and the specific model can be determined on the type spectrum or series characteristic curve.
3, according to the nature of the liquid medium, determine the clean water pump, hot water pump, chemical pump or corrosion-resistant pump or impurity pump, or use non-blocking pump. In the case of pumps installed in explosive areas, explosion-proof motors shall be used according to the grade of the explosive area.
Consider the type of water ring vacuum pump, horizontal, vertical or other types.
5. According to the head level, choose whether a single suction pump or a multi-suction pump, a high-speed pump or a low-speed pump (air-conditioning pump), and the efficiency of a multi-stage pump is lower than that of a single-stage pump.
6, considering the amount of vibration, it is divided into: pneumatic, electric (electric is divided into 220v voltage and 380v voltage).
Therefore, the purchase of water ring vacuum pumps should be considered from many aspects. For laymen, they may not be familiar with these parameters, so users should have a deeper understanding,
