消毒液加藥計(jì)量泵流量偏小的故障原因與使用注意事項(xiàng)
在當(dāng)前的防疫形勢(shì)下，消毒劑加藥裝置的使用越來越多。在使用過程中，其核心部件之一的消毒劑加藥計(jì)量泵出現(xiàn)問題的概率較高。例如，消毒劑加藥裝置工作時(shí)，流量過小。事實(shí)上，這是有原因的。下面介紹了幾種VAREM計(jì)量泵流量過小的可能原因，并提供了相應(yīng)的解決方案供大家參考！
消毒劑計(jì)量泵故障原因：
1、異物進(jìn)入進(jìn)出口止回閥，導(dǎo)致止回閥關(guān)閉不嚴(yán)
2、進(jìn)出口止回閥磨損
3、液壓油室內(nèi)有空氣
4、內(nèi)置加油閥關(guān)不嚴(yán)
5、內(nèi)置排氣閥排氣不正常
6、柱塞密封磨損
7、液壓油品牌不對(duì)
8、行程速度與模型不一致
9、雙隔膜之間的排氣不足
10、雙膜片間排氣門內(nèi)漏
解決方案：
1、拆下入口和出口止回閥進(jìn)行清潔或更換
2、更換止回閥總成或閥球和閥座
3、排出液壓油室。您可以添加機(jī)油排氣或保持壓力釋放排氣
4、更換內(nèi)置注油閥
5、更換或清潔內(nèi)置排氣閥
6、更換柱塞密封件
7、更換正確品牌的液壓油
8、如果行程速度不一致，更換蝸輪/蝸桿組件
9、對(duì)雙隔膜總成排氣并用真空吸塵
10、更換雙膜片總成排氣閥
最近，VAREM消毒劑計(jì)量泵的一些客戶問：您能對(duì)計(jì)量泵揚(yáng)程的解決方案提出一些建議嗎？化學(xué)品引起泵頭/密封損壞時(shí)會(huì)出現(xiàn)什么問題，如何防止？在WATERSUNNY計(jì)量泵揚(yáng)程方面，一般問題出現(xiàn)在酸、氯、氟化物和過氧化氫的測(cè)量環(huán)境中。由于藥物濃度和溫度的差異，超精密泵頭材料的確定比較困難。
如何調(diào)節(jié)VAREM消毒劑加藥計(jì)量泵的背壓閥？
1） 當(dāng)消毒劑計(jì)量泵吸入端有壓力時(shí)，泵的實(shí)際壓力應(yīng)至少比吸入端的壓力高1巴。
2） 不要越過VAREM消毒劑計(jì)量泵的允許壓力。
安全閥的壓力可在計(jì)量泵的額定壓力范圍內(nèi)調(diào)節(jié)，不允許越過計(jì)量泵的允許壓力。安全閥用于防止計(jì)量泵超壓運(yùn)行。例如，如果計(jì)量泵的允許壓力為3bar，則安全閥的壓力應(yīng)設(shè)置為3bar，并應(yīng)盡可能降低，以保證鈦龍計(jì)量泵的正常運(yùn)行。超壓事故是VAREM消毒劑加藥計(jì)量泵損壞的原因之一。
消毒劑加藥計(jì)量泵可測(cè)量輸送液體的剛度，常用于各類試劑加藥成套設(shè)備中，故又稱加藥泵。因此，VAREM消毒劑加藥計(jì)量泵是一種能滿足各種苛刻工藝流程的泵。流量可在0-100%范圍內(nèi)無級(jí)調(diào)節(jié)。消毒劑計(jì)量泵是一種用于輸送液體（特別是腐蝕性液體）的專用容積泵。
Causes of small flow of disinfectant dosing metering pump and precautions
In the current epidemic situation, more and more disinfectant dosing devices are used. In the process of use, the probability of problems of disinfectant dosing metering pump, one of its core components, is high. For example, when the disinfectant dosing device works, the flow is too small. In fact, there is a reason. The following introduces several possible reasons for small flow of VAREM metering pump, and provides corresponding solutions for your reference!
Cause of failure:
1. Foreign matters enter the inlet and outlet check valves, resulting in the check valve not closed tightly
2. Wear of inlet and outlet check valves
3. There is air in the hydraulic oil chamber
4. The built-in refueling valve is not closed tightly
5. Abnormal exhaust of built-in exhaust valve
6. Wear of plunger seal
7. Wrong brand of hydraulic oil
8. The travel speed is inconsistent with the model
9. Insufficient exhaust between two diaphragms
10. Internal leakage of exhaust valve between two diaphragms
Solution:
1. Remove the inlet and outlet check valves for cleaning or replacement
2. Replace check valve assembly or ball and seat
3. Drain the hydraulic oil chamber. You can add oil to exhaust or keep the pressure to release the exhaust
4. Replace the built-in oil filling valve
5. Replace or clean the built-in exhaust valve
6. Replace the plunger seal
7. Replace the correct brand of hydraulic oil
8. If the travel speed is inconsistent, replace the worm gear / worm assembly
9. Exhaust the double diaphragm assembly and vacuum it
10. Replace the exhaust valve of double diaphragm assembly
Recently, some customers of VAREM disinfectant metering pump asked: can you give some suggestions on the solution of metering pump head? What problems will occur when the pump head / seal is damaged by chemicals and how to prevent them? In the aspect of watersunny metering pump head, the general problems appear in the measurement environment of acid, chlorine, fluoride and hydrogen peroxide. Due to the difference of drug concentration and temperature, it is difficult to determine the material of ultra precision pump head.
How to adjust the back pressure valve of VAREM disinfectant dosing metering pump?
1) When there is pressure at the suction end of the metering pump, the actual pressure of the pump should be at least 1 bar higher than the pressure at the suction end.
2) Do not exceed the allowable pressure of the VAREM disinfectant metering pump.
The pressure of the safety valve can be adjusted within the rated pressure range of the metering pump, and it is not allowed to exceed the allowable pressure of the metering pump. The safety valve is used to prevent the metering pump from overpressure operation. For example, if the allowable pressure of the metering pump is 3bar, the pressure of the safety valve should be set to 3bar and should be reduced as far as possible to ensure the normal operation of the Tailong metering pump. Overpressure accident is one of the reasons for the damage of VAREM disinfectant dosing metering pump.
Disinfectant dosing metering pump can measure the stiffness of liquid delivery, which is commonly used in all kinds of reagent dosing equipment, so it is also called dosing pump. Therefore, VAREM disinfectant dosing metering pump is a kind of pump that can meet various harsh process flow. The flow rate can be adjusted steplessly in the range of 0-100%. It is a kind of special positive displacement pump for conveying liquid (especially corrosive liquid).
