如何處理鈦龍計量泵系統(tǒng)中的氣蝕現(xiàn)象？一個計量泵維修老師傅的多年心得
計量泵安裝自排泵頭時，采用自吸法測量過氧化氫時，系統(tǒng)會產(chǎn)生氣蝕現(xiàn)象。怎么處理？上海龍亞泵閥制造有限公司共享一個非常簡單的方法：計量泵安裝自排泵頭，采用自充式抽吸。保持吸入管路盡可能短。所以沒有氣蝕。
計量泵隔膜更換工藝
、在更換隔膜的過程中，計量泵需要遵循一定的步驟。首先，拆下固定泵頭的四個螺釘。螺釘位置在計量泵的背面。然后，在松開泵頭后，在拆卸泵頭之前，將沖程長度調(diào)整到0%位置。它能保證電磁軸有足夠的壓力保持其連接的穩(wěn)定，從而使隔膜能夠被擰松。從內(nèi)端將螺釘從插座中拔出。握住液體端，逆時針旋轉(zhuǎn)。只要稍有阻力，隔膜就可以擰松。隔膜拆除后，檢查計量泵的安全隔膜，確保其完好無損。安裝新的隔膜，順時針旋轉(zhuǎn)背板和隔膜，直到它們擰緊。調(diào)整背板，使泄漏排放孔位于泵的底部Z。隔膜安裝完畢，背板上的排水孔處于垂直位置后，安裝泵頭。確保吸入閥與泄漏孔對齊，液壓端的螺釘與相應(yīng)的4個孔對齊。旋轉(zhuǎn)到筆劃長度的100%。這樣，就可以轉(zhuǎn)動整套零件，直到背板的排水孔與泵的Z底端對齊為止。在泵運行過程中，將液壓端和隔膜調(diào)整到正確的位置。調(diào)整液壓端和背板位置時，應(yīng)對角擰緊4個螺栓，直到合適為止。更換計量泵隔膜時，應(yīng)力應(yīng)均勻。
機械隔膜計量泵選型參考
機械隔膜計量泵直接驅(qū)動蝸輪蝸桿變速運動。一般來說，活動部件越少，計量泵的工作就越可靠。選擇類型時可參考以下因素。1被測液體的流速。
2、鈦龍計量泵計量液體的主要特性，如化學(xué)腐蝕性、粘度和比重。
3、系統(tǒng)背壓。
4、適當(dāng)?shù)奈�入高度�?br />5、監(jiān)控定時器，其他流量控制選項，如脈沖控制。

How to deal with the cavitation phenomenon in the titanium dragon metering pump system? Experience of an old maintenance master of metering pump
When the metering pump is installed with self discharge pump head, the system will produce cavitation when the self suction method is used to measure hydrogen peroxide. How to deal with it? Shanghai Longya pump valve manufacturing Co., Ltd. shares a very simple method: the metering pump is installed with a self discharge pump head and self charging suction is adopted. Keep the suction line as short as possible. So there is no cavitation.
Diaphragm replacement process of metering pump
In the process of diaphragm replacement, the metering pump needs to follow certain steps. First, remove the four screws that hold the pump head. The screw location is on the back of the metering pump. Then, after loosening the pump head, adjust the stroke length to 0% before removing the pump head. It can ensure that the electromagnetic shaft has enough pressure to maintain the stability of its connection, so that the diaphragm can be unscrewed. Pull the screw out of the socket from the inner end. Hold the liquid end and rotate counterclockwise. As long as there is a little resistance, the diaphragm can be loosened. After the diaphragm is removed, check the safety diaphragm of the metering pump to ensure that it is intact. Install the new diaphragm and rotate the back plate and diaphragm clockwise until they are tight. Adjust the back plate so that the leakage drain hole is at the bottom Z of the pump. After the diaphragm is installed and the drain hole on the back plate is in the vertical position, install the pump head. Make sure that the suction valve is aligned with the leak hole and that the screw on the hydraulic end is aligned with the corresponding 4 holes. Rotate to 100% of the stroke length. In this way, the complete set of parts can be turned until the drain hole of the back plate is aligned with the bottom Z end of the pump. Adjust the hydraulic end and diaphragm to the correct position during pump operation. When adjusting the position of hydraulic end and back plate, tighten 4 bolts diagonally until they are suitable. When replacing the diaphragm of metering pump, the stress should be uniform.
Selection reference of mechanical diaphragm metering pump
The mechanical diaphragm metering pump directly drives the worm gear to move at variable speed. Generally speaking, the less moving parts, the more reliable the metering pump works. The following factors can be taken into account when selecting the type. 1 the flow rate of the measured liquid.
2. The main characteristics of the metered liquid, such as chemical corrosivity, viscosity and specific gravity.
3. System back pressure.
4. Proper suction height.
5. Monitor timer, other flow control options, such as pulse control.
Well, the above is how to deal with the cavitation phenomenon in the titanium dragon metering pump system. This is the experience of Shanghai Longya metering pump maintenance old master for many years. This article is for your reference.
