LYJY加藥裝置的選型方法及加藥泵的隔膜片更換方法
1、用戶在選擇一套完整的加藥裝置時，應根據系統所需的溶液量確定選擇規格（包括加藥泵參數、攪拌罐容積、溶液罐容積、現場條件等），然后由加藥裝置的生產廠家確定加藥方式根據加藥情況（一般采用“一人一備”或“一人多備”的方式）；
2、根據需要，選擇輔助加藥裝置部件的材質（不銹鋼、碳鋼、非金屬材料）、加藥泵（隔膜泵、柱塞泵）的廠家型號或投加化學品的參數（名稱、濃度、溫度、密度、粘度、腐蝕性等）；
3、訂貨系統為多箱多泵；
4、加藥泵是柱塞泵還是隔膜泵；
5、ZILMET加藥泵流量、壓力；
6、系統是手動控制還是自動控制；
7、加藥裝置的其他特殊要求。
ZILMET加藥泵在目前的泵市場上使用越來越多，其中隔膜加藥泵在特殊環境下使用較多，但在使用過程中，由于操作不當或其他原因，隔膜會損壞，一旦發現加藥泵隔膜損壞而不及時更換，會造成不滿意的結果，所以加藥泵的隔膜會損壞，如何更換損壞的零件？介紹龍亞ZILMET加藥泵的更換步驟。
1、拆下固定泵頭的4個螺釘。螺釘位于加藥泵的背面。
2、泵頭松動后，在拆卸泵頭之前，將行程長度調整到0%。它能保證電磁軸有足夠的壓力保持其連接的穩定，從而使隔膜能夠被擰松。
3、從液壓插座上向外拉螺絲。握住液體端并逆時針旋轉。只要稍有阻力，隔膜就可以擰松。
4、隔膜拆除后，檢查ZILMET加藥泵安全隔膜完好，無損壞。安裝一個新的膜片，順時針旋轉背板和膜片，直到它們擰緊為止。調整背板，使泄漏排放孔位于泵的底部Z。
5、隔膜安裝完畢，背板泄漏孔處于垂直位置后，安裝泵頭。確保吸入閥與泄漏孔對齊，液壓端的螺釘與相應的四個孔對齊。
6、旋轉到筆劃長度的100%。這樣，就可以轉動整套零件，直到背板泄漏孔與泵的底部Z端對齊為止。在加藥泵運行過程中，將液壓端和隔膜調整到正確的位置。
7、ZILMET加藥泵液壓端與背板調整好后，對角擰緊四個螺栓至合適為止。這項工作應該用力均勻。

Selection method of LYJY dosing device and replacement method of diaphragm of dosing pump
1. When selecting a complete set of dosing device, the user should determine the selection specifications (including dosing pump parameters, mixing tank volume, solution tank volume, site conditions, etc.) according to the solution volume required by the system, and then the manufacturer of the dosing device determines the dosing method according to the dosing situation (generally, the method of "one person one standby" or "one person multiple standby" is adopted);
2. According to the needs, select the material of auxiliary dosing device components (stainless steel, carbon steel, non-metallic materials), the manufacturer model of dosing pump (diaphragm pump, plunger pump) or the parameters of dosing chemicals (name, concentration, temperature, density, viscosity, corrosivity, etc.);
3. The ordering system is multi tank and multi pump;
4. Is the dosing pump a plunger pump or a diaphragm pump;
5. Flow and pressure of ZILMET dosing pump;
6. Whether the system is controlled manually or automatically;
7. Other special requirements of dosing device.
Zilmet dosing pump is used more and more in the current pump market, in which diaphragm dosing pump is used more in special environment. However, in the process of use, the diaphragm will be damaged due to improper operation or other reasons. Once the diaphragm of dosing pump is found damaged and not replaced in time, it will lead to unsatisfactory results. Therefore, the diaphragm of dosing pump will be damaged. How to replace the damaged parts? The replacement procedure of Longya pump is introduced.
1. Remove the four screws that hold the pump head. The screw is located on the back of the dosing pump.
2. After the pump head is loose, adjust the stroke length to 0% before removing the pump head. It can ensure that the electromagnetic shaft has enough pressure to keep its connection stable, so that the diaphragm can be loosened.
3. Pull the screw outward from the hydraulic socket. Hold the liquid end and rotate counterclockwise. As long as there is a little resistance, the diaphragm can be loosened.
4. After the diaphragm is removed, check whether the safety diaphragm of ZILMET dosing pump is in good condition without damage. Install a 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 located at the bottom Z of the pump.
5. After the diaphragm is installed and the back plate leakage hole 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 four holes.
6. Rotate to 100% of stroke length. In this way, the whole set of parts can be rotated until the back plate leakage hole is aligned with the bottom Z end of the pump. During the operation of the pump, adjust the hydraulic end and diaphragm to the correct position.
7. After adjusting the hydraulic end and back plate of zilmet dosing pump, tighten four bolts diagonally until they are suitable. The work should be done evenly.
Well, the above is the discussion of LYJY dosing device selection method and dosing pump diaphragm replacement method. More dosing device and dosing pump problems are welcome to discuss with Shanghai Longya pump valve technology department!
