加藥泵使用中的注意事項(xiàng)及穩(wěn)定流量的方法
在使用VAREM加藥泵時(shí)，應(yīng)參考一些注意事項(xiàng)，以確保平穩(wěn)運(yùn)行。上海龍亞提醒每位用戶在使用加藥泵時(shí)，要嚴(yán)格遵循以下步驟：
一、確保每臺(tái)加藥泵有獨(dú)立的閥門控制（可選擇旁路安裝）；
二、第一次打開進(jìn)水閥，使加藥泵逐漸進(jìn)水；
三、當(dāng)腔內(nèi)充滿水時(shí)，吸藥管開始工作。為了減少吸入管產(chǎn)生真空吸入所需的時(shí)間，盡可能將噴射比例調(diào)整到Z的最大值。一旦產(chǎn)生真空吸力，噴射比例將調(diào)整到所需值；
四、大多數(shù)加藥泵的頂部都有一個(gè)排氣按鈕。使用時(shí)，按此按鈕可將集中在頂部的空氣排出。當(dāng)您看到VAREM加藥泵的連續(xù)水流從按鈕周圍溢出（而不是噴灑），只需松開排氣按鈕。
以上是使用VAREM加藥泵時(shí)的注意事項(xiàng)，讓我們了解如何穩(wěn)定計(jì)量泵中的流量？
計(jì)量泵在輸送流量時(shí)，經(jīng)常需要做往復(fù)運(yùn)動(dòng)。為了保證機(jī)組所需流量，瓦雷姆加藥泵必須穩(wěn)定流速，保證合理供給。當(dāng)計(jì)量泵流量穩(wěn)定時(shí)，應(yīng)避免以下三項(xiàng)：避免柱塞密封處泄漏；避免氣體進(jìn)入液壓腔；避免補(bǔ)油過多或排放管路壓力意外升高。以上三個(gè)問題都會(huì)影響流量的穩(wěn)定性，降低泵的計(jì)量精度。為了穩(wěn)定流量，計(jì)量泵通常采用補(bǔ)償、放空、安全保護(hù)三種功能的裝置或裝置組合。
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.
