了解ZILMET机械隔膜计量泵的大概价格，就可以了解ZILMET机械隔膜计量泵的选择方法。
1、 确定压力：所选计量泵的额定压力略高于实际需要的z高压，一般高出10-20%。不要选择过高、过高的压力会浪费能源，增加设备投资和运行成本。
2、 确定流量：所选计量泵流量应等于或略大于工艺所需流量。计量泵的流量范围最好在计量泵额定流量范围的30-100%范围内。此时，计量泵的重复精度高。考虑到经济性和实用性，建议计量泵的实际流量应为计量泵额定流量的70-90%。
3、 确定泵头（液端）材质：在确定计量泵的具体型号和规格后，根据流动介质的性质选择溢流部分的材料。如果选材不当，会造成介质腐蚀，损坏过流部件或介质泄漏，污染系统。也可能发生严重事故。其他方面：在选择计量泵时，还需要考虑计量泵的精度水平，精度水平越高，投资就越大。计量泵的计量温度一般在30～500℃之间，计量泵工作温度可达到100℃以上。介质的粒径应小于0.1mm。对于大于0.1mm的介质，可根据需要改变泵的溢流结构。对于介质粘度，一般应为0~1000mm/s，专用计量泵可达到6000mm2/s，机械隔膜计量泵的流量为Z大流量，在额定压力下测得（室温下送水时），如果ZILMET机械隔膜计量泵压力下降，输出流量将高于标定值。特征

1、铸铝外壳，散热性能高，整机重量轻，适用于各种酸碱溶液，无毒无味。
2、采用凸轮机构。整体无泄漏，可放置在药箱或管路上。
3、接触介质泵头由聚氯乙烯、聚四氟乙烯和不锈钢制成。
4、由于其高性价比，它被广泛应用于对压力要求较低的水处理行业。
5、当泵运行或停止时，也可以随意调节流量，并可量化输出。
6、ZILMET机械隔膜计量泵隔膜采用多层复合结构，Dy层为超韧聚四氟乙烯耐酸膜，第二层为EPDM弹性橡胶，第三层为厚支承铁芯，第四层为增强尼龙纤维增强，第五层为全覆盖采用三元乙丙橡胶弹性体，能有效提高隔膜的使用寿命。
Selection method and approximate price of zilmet mechanical diaphragm metering pump
With the development of the times and continuous improvement and improvement, more and more fields need to use mechanical diaphragm metering pump. After continuous upgrading, zilmet mechanical diaphragm metering pump performance is very good, let everyone like this product. Then the problem came. A question that many people are very concerned about is how good the price of zilmet mechanical diaphragm metering pump is. Let's find out.
Through relevant understanding, we can know that the price of mechanical diaphragm metering pump is not very expensive, but tends to a reasonable level. Of course, when ordering, we should follow the principle of comparing products with the three manufacturers to help you choose the mechanical diaphragm metering pump with higher cost performance. Brand words, such as varem, zilmet, watersunny, titanium dragon and other mechanical diaphragm metering pump is a good choice.
Understand the approximate price of qimeite mechanical diaphragm metering pump, you can understand the selection method of qimeite mechanical diaphragm metering pump.
1. Determined pressure: the rated pressure of the selected metering pump is slightly higher than the actual need of Z high pressure, generally 10-20% higher. Do not choose too high, too high pressure will waste energy, increase equipment investment and operating costs.
2. Determine the flow rate: the flow rate of the selected metering pump should be equal to or slightly greater than the flow required by the process. The best flow range of metering pump is 30-100% of rated flow range of metering pump. At this time, the repetition accuracy of the metering pump is high. Considering the economy and practicability, it is suggested that the actual flow rate of the metering pump should be 70-90% of the rated flow of the metering pump.
3. Determine the material of pump head (liquid end): after determining the specific model and specification of metering pump, select the material of overflow part according to the property of flowing medium. If the material is not selected properly, it will cause the medium corrosion, damage the flow passage parts or medium leakage, and pollute the system. Serious accidents may also occur. Other aspects: when selecting the metering pump, the accuracy level of the metering pump should be considered. The higher the accuracy level, the greater the investment. The measuring temperature of the metering pump is generally between 30 ℃ and 500 ℃, and the working temperature of the metering pump can reach more than 100 ℃. The particle size of the medium should be less than 0.1 mm. For the medium larger than 0.1 mm, the overflow structure of the pump can be changed as required. For the medium viscosity, generally should be 0 ~ 1000mm / s, special metering pump can reach 6000mm2 / s, the flow of mechanical diaphragm metering pump is Z large flow, measured under rated pressure (when water is delivered at room temperature), if the pressure drops, the output flow will be higher than the calibration value. features
Measurement range: 0-400l / h
Pressure range: 0-1.0mpa
Driving mode: motor driven
Control mode: manual and automatic control (can receive 4-20mA signal to adjust flow)
1. Cast aluminum shell, high heat dissipation performance, light weight, suitable for all kinds of acid-base solution, non-toxic and tasteless.
2. Cam mechanism is adopted. It can be placed on the medicine box or pipeline.
3. Contact medium pump head is made of PVC, PTFE and stainless steel.
4. Because of its high cost performance, it is widely used in water treatment industry with low pressure requirements.
5. When the pump is running or stopped, the flow can be adjusted at will and the output can be quantified.
6. The diaphragm of zilmet mechanical diaphragm metering pump adopts multi-layer composite structure, Dy layer is super tough PTFE acid resistant film, the second layer is EPDM elastic rubber, the third layer is thick support iron core, the fourth layer is reinforced nylon fiber reinforcement, the fifth layer is full coverage, using EPDM elastomer, which can effectively improve the service life of diaphragm.
