加药计量泵管道产生噪声的原因是什么？
加药计量泵工作时，有时管道会产生噪音。为什么？VAREM加药计量泵的兼容性不是很强吗？如何解决噪音现象？
首先分析加药计量泵管路噪声产生的原因，主要有以下四个原因：
1、管线过长；
2、加药计量泵管径过小；
3、不使用腔室或阻尼器。
4、VAREM加药计量泵脉冲挡板不工作或溢流；
针对以上四个原因，上海龙亚泵阀有限公司依次给出了相应的解决方案
1、增加管道尺寸，安装脉冲阻尼器；
2、脉冲阻尼器安装在管道中；
3、重新充入空气或惰性气体，检查并更换隔膜，重新充入；
4、安装脉冲阻尼器。
加药计量泵运行时如何调整背压阀？
加药计量泵运行时，需要使用安全阀，那么如何调整安全阀呢？安全阀相当于背压阀。背压阀的压力需要合理控制。加药计量泵的安全阀的设计是为了防止加药计量泵超压运行，那么在运行过程中如何调整背压阀呢？
1、切勿超过VAREM计量泵的工作压力。
2、当加药计量泵吸入端有压力时，泵排出端的压力应至少比吸入端的压力高1BAR。
What is the cause of noise in the pipe of dosing metering pump?
When the dosing metering pump works, sometimes the pipe will produce noise. Why? Isn't the compatibility of VAREM metering pump very strong? How to solve the noise phenomenon?
Firstly, the causes of pipe noise of dosing metering pump are analyzed, which mainly include the following four reasons:
1. The pipeline is too long;
2. The pipe diameter is too small;
3. No chambers or dampers are used.
4. The pulse baffle of VAREM dosing metering pump does not work or overflows;
In view of the above four reasons, Shanghai Longya pump valve Co., Ltd. gives the corresponding solutions in turn
1. Increase the pipe size and install pulse damper;
2. The pulse damper is installed in the pipeline;
3. Refill air or inert gas, check and replace diaphragm, refill;
4. Install pulse damper.
How to adjust the back pressure valve when the dosing metering pump is running?
When the dosing metering pump is running, it needs to use the safety valve, so how to adjust the safety valve? The safety valve is equivalent to the back pressure valve. The pressure of back pressure valve needs to be controlled reasonably. The safety valve is designed to prevent the dosing metering pump from overpressure operation, so how to adjust the back pressure valve in the operation process?
1. Do not exceed the working pressure of the VAREM metering pump.
2. When there is pressure at the suction end of the dosing metering pump, the pressure at the discharge end of the pump should be at least 1bar higher than that at the suction end.
