加藥計量泵管道產(chǎn)生噪聲的原因是什么？
加藥計量泵工作時，有時管道會產(chǎn)生噪音。為什么？VAREM加藥計量泵的兼容性不是很強嗎？如何解決噪音現(xiàn)象？
首先分析加藥計量泵管路噪聲產(chǎn)生的原因，主要有以下四個原因：
1、管線過長；
2、加藥計量泵管徑過小；
3、不使用腔室或阻尼器。
4、VAREM加藥計量泵脈沖擋板不工作或溢流；
針對以上四個原因，上海龍亞泵閥有限公司依次給出了相應(yīng)的解決方案
1、增加管道尺寸，安裝脈沖阻尼器；
2、脈沖阻尼器安裝在管道中；
3、重新充入空氣或惰性氣體，檢查并更換隔膜，重新充入；
4、安裝脈沖阻尼器。
加藥計量泵運行時如何調(diào)整背壓閥？
加藥計量泵運行時，需要使用安全閥，那么如何調(diào)整安全閥呢？安全閥相當(dāng)于背壓閥。背壓閥的壓力需要合理控制。加藥計量泵的安全閥的設(shè)計是為了防止加藥計量泵超壓運行，那么在運行過程中如何調(diào)整背壓閥呢？
1、切勿超過VAREM計量泵的工作壓力。
2、當(dāng)加藥計量泵吸入端有壓力時，泵排出端的壓力應(yīng)至少比吸入端的壓力高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.
