了解ZILMET機械隔膜計量泵的大概價格，就可以了解ZILMET機械隔膜計量泵的選擇方法。
1、 確定壓力：所選計量泵的額定壓力略高于實際需要的z高壓，一般高出10-20%。不要選擇過高、過高的壓力會浪費能源，增加設備投資和運行成本。
2、 確定流量：所選計量泵流量應等于或略大于工藝所需流量。計量泵的流量范圍最好在計量泵額定流量范圍的30-100%范圍內。此時，計量泵的重復精度高。考慮到經濟性和實用性，建議計量泵的實際流量應為計量泵額定流量的70-90%。
3、 確定泵頭（液端）材質：在確定計量泵的具體型號和規格后，根據流動介質的性質選擇溢流部分的材料。如果選材不當，會造成介質腐蝕，損壞過流部件或介質泄漏，污染系統。也可能發生嚴重事故。其他方面：在選擇計量泵時，還需要考慮計量泵的精度水平，精度水平越高，投資就越大。計量泵的計量溫度一般在30～500℃之間，計量泵工作溫度可達到100℃以上。介質的粒徑應小于0.1mm。對于大于0.1mm的介質，可根據需要改變泵的溢流結構。對于介質粘度，一般應為0~1000mm/s，專用計量泵可達到6000mm2/s，機械隔膜計量泵的流量為Z大流量，在額定壓力下測得（室溫下送水時），如果ZILMET機械隔膜計量泵壓力下降，輸出流量將高于標定值。特征

4、由于其高性價比，它被廣泛應用于對壓力要求較低的水處理行業。
5、當泵運行或停止時，也可以隨意調節流量，并可量化輸出。
6、ZILMET機械隔膜計量泵隔膜采用多層復合結構，Dy層為超韌聚四氟乙烯耐酸膜，第二層為EPDM彈性橡膠，第三層為厚支承鐵芯，第四層為增強尼龍纖維增強，第五層為全覆蓋采用三元乙丙橡膠彈性體，能有效提高隔膜的使用壽命。
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.
