在保证的中等温度范围内，应在 -10至80摄氏度之间。但是，如果有特殊情况，温度可以达到120摄氏度。每个阶段的正常压力为0.6 mpa。如果在很短的时间内，可以达到0.8 mpa。
1 single screw pump in the guarantee medium, should pay attention to what details?
Single screw pump, in the guarantee medium, there are some precautions, so we need to understand and control, so as to avoid problems, so next, immediately to elaborate.
Within the guaranteed moderate temperature range, it should be between -10 and 80 degrees Celsius. However, if there are special circumstances, the temperature can reach 120 degrees Celsius. The normal pressure at each stage is 0.6mpa. If in a very short period of time, can reach 0.8 mpa.
When the single screw pump to ensure the delivery of clean water, its maximum suction range of 8m, but in the actual operation process, it is recommended not to exceed 6.5m, to avoid problems. In addition, if it is a high viscosity medium, positive pressure attraction should be used, which is better.
2. Single screw pump, can be used to stop the gas-liquid mixture, to ensure delivery?
Can it be divided into single suction and double suction? Single screw pump can be used to ensure that the gas liquid mixed medium, which in the single screw pump consumer Hua Longchang, is not appropriate, because it is not appropriate, so it is not appropriate. As for the latter issue, of course, screw pump is single and double suction two types, and single screw pump is a screw pump. However, single screw pump, as long as it is single suction, there is no double suction.
3 why the screw pump in the three screw pump, can only be used to transport clean liquid?
Three screw pump, its structure, data, etc., have certain limitations. In addition, volumetric efficiency decreases as discharge pressure increases. Therefore, this screw pump, mainly used to transport clean liquid, so as to avoid problems. In addition, it is also necessary to know that for single screw pump, in the guarantee medium, is not suitable for any situation.
