如何处理钛龙计量泵系统中的气蚀现象？一个计量泵维修老师傅的多年心得
计量泵安装自排泵头时，采用自吸法测量过氧化氢时，系统会产生气蚀现象。怎么处理？上海龙亚泵阀制造有限公司共享一个非常简单的方法：计量泵安装自排泵头，采用自充式抽吸。保持吸入管路尽可能短。所以没有气蚀。
计量泵隔膜更换工艺
、在更换隔膜的过程中，计量泵需要遵循一定的步骤。首先，拆下固定泵头的四个螺钉。螺钉位置在计量泵的背面。然后，在松开泵头后，在拆卸泵头之前，将冲程长度调整到0%位置。它能保证电磁轴有足够的压力保持其连接的稳定，从而使隔膜能够被拧松。从内端将螺钉从插座中拔出。握住液体端，逆时针旋转。只要稍有阻力，隔膜就可以拧松。隔膜拆除后，检查计量泵的安全隔膜，确保其完好无损。安装新的隔膜，顺时针旋转背板和隔膜，直到它们拧紧。调整背板，使泄漏排放孔位于泵的底部Z。隔膜安装完毕，背板上的排水孔处于垂直位置后，安装泵头。确保吸入阀与泄漏孔对齐，液压端的螺钉与相应的4个孔对齐。旋转到笔划长度的100%。这样，就可以转动整套零件，直到背板的排水孔与泵的Z底端对齐为止。在泵运行过程中，将液压端和隔膜调整到正确的位置。调整液压端和背板位置时，应对角拧紧4个螺栓，直到合适为止。更换计量泵隔膜时，应力应均匀。
机械隔膜计量泵选型参考
机械隔膜计量泵直接驱动蜗轮蜗杆变速运动。一般来说，活动部件越少，计量泵的工作就越可靠。选择类型时可参考以下因素。1被测液体的流速。
2、钛龙计量泵计量液体的主要特性，如化学腐蚀性、粘度和比重。
3、系统背压。
4、适当的吸入高度。
5、监控定时器，其他流量控制选项，如脉冲控制。

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.
