加药泵使用中的注意事项及稳定流量的方法
在使用VAREM加药泵时，应参考一些注意事项，以确保平稳运行。上海龙亚提醒每位用户在使用加药泵时，要严格遵循以下步骤：
一、确保每台加药泵有独立的阀门控制（可选择旁路安装）；
二、第一次打开进水阀，使加药泵逐渐进水；
三、当腔内充满水时，吸药管开始工作。为了减少吸入管产生真空吸入所需的时间，尽可能将喷射比例调整到Z的最大值。一旦产生真空吸力，喷射比例将调整到所需值；
四、大多数加药泵的顶部都有一个排气按钮。使用时，按此按钮可将集中在顶部的空气排出。当您看到VAREM加药泵的连续水流从按钮周围溢出（而不是喷洒），只需松开排气按钮。
以上是使用VAREM加药泵时的注意事项，让我们了解如何稳定计量泵中的流量？
计量泵在输送流量时，经常需要做往复运动。为了保证机组所需流量，瓦雷姆加药泵必须稳定流速，保证合理供给。当计量泵流量稳定时，应避免以下三项：避免柱塞密封处泄漏；避免气体进入液压腔；避免补油过多或排放管路压力意外升高。以上三个问题都会影响流量的稳定性，降低泵的计量精度。为了稳定流量，计量泵通常采用补偿、放空、安全保护三种功能的装置或装置组合。
Matters needing attention in use of dosing pump and methods of stabilizing flow
When using VAREM dosing pump, we should refer to some precautions to ensure smooth operation. Shanghai Longya reminds each user to strictly follow the following steps when using the dosing pump:
Each pump can be installed with an independent control valve;
2. Open the inlet valve for the first time to make the dosing pump gradually feed water;
3. When the cavity is full of water, the medicine suction tube starts to work. In order to reduce the time required for vacuum suction in the suction pipe, the injection proportion should be adjusted to the maximum value of Z as far as possible. Once the vacuum suction is generated, the injection proportion will be adjusted to the required value;
4.Most dosing pumps have a vent button on the top. When in use, press this button to exhaust the air concentrated on the top. When you see the continuous flow of water from the VAREM dosing pump overflowing around the button (instead of spraying), just release the vent button.
The above are the precautions when using the varem dosing pump. Let's know how to stabilize the flow in the metering pump?
Metering pump in the delivery flow, often need to do reciprocating motion. In order to ensure the required flow of the unit, the varem dosing pump must stabilize the flow rate to ensure reasonable supply. When the flow rate of metering pump is stable, the following three items should be avoided: to avoid leakage at the plunger seal; to avoid gas entering the hydraulic cavity; to avoid excessive oil filling or unexpected increase of discharge pipeline pressure. The above three problems will affect the stability of the flow and reduce the metering accuracy of the pump. In order to stabilize the flow, the metering pump usually uses three functions of compensation, venting and safety protection.
