每臺電子計量泵都經(jīng)試驗，符合規(guī)定的技術(shù)規(guī)范和**標(biāo)準(zhǔn)。
正確、小心地搬運、安裝和操作有助于確保無故障安裝。
? 搬運泵時要小心。跌落或重?fù)舨粌H會造成泵的外部損壞，而且還會損壞其內(nèi)部電子部件。
? 泵安裝地點的環(huán)境溫度不能超過104°F (40°C)。泵可防水防塵，可用于室外，但是不能浸在 水中使用。不要在直射陽光下運行，防止泵的內(nèi)部溫度升高。
IA小心 丨電磁線圈外殼、泵頭和泵殼可能高溫160°F(70°C),不可接觸。
? 泵的安裝地點要方便將來的維護和檢驗。泵要固定，避免振動。
? 在將管道安裝到閥門組件上之前，必須先卸下保護帽。使用規(guī)定尺寸的管道。將管道牢固地 連接到吸入端，防止外部空氣進入。確保排出端無液體泄漏。
? 小心檢查裝置電壓與計量泵數(shù)據(jù)標(biāo)簽上指示的電壓是否-致。大多數(shù)型號的泵配有-個三叉 塞。務(wù)必確保計量泵接地。斷開連接時，不要拔電線，而是用手指夾住塞子，然后拔出。不 要使用與重型電氣設(shè)備共用的插座，重型電氣設(shè)備會產(chǎn)生沖擊電壓。沖擊電壓會使泵內(nèi)的電 子電路產(chǎn)生故障。
?擅自改動電氣裝置有潛在危險。務(wù)必將化學(xué)藥品和泵裝置放在兒童不能接觸到的地方。
? 決不要在計量泵運行時修理或移動泵。-定要斷開電源。為了**，在操作化學(xué)計量泵或靠 近泵時務(wù)必穿戴防護服(防護手套和護目鏡)。
? 大多數(shù).型號都配備帶有管接頭的放氣閥。啟動時，應(yīng)在泵室內(nèi)沒有流體時實施空氣吹掃。為 確保**，將回流管道連接到放氣閥，并使流體旁路回到儲槽或合適的排液管。
? 為了使體積輸出準(zhǔn)確，泵必須在典型的運行條件下標(biāo)定。
? 使用的化學(xué)藥品可能有危險，應(yīng)小心按照標(biāo)簽上的警告信息使用。遵守每種化學(xué)藥品的說明。 不要因為化學(xué)藥品相似而認(rèn)為它們相同。務(wù)必將化學(xué)藥品儲存在**地點，遠(yuǎn)離兒童和其他 人員。我們對誤用計量泵給送的化學(xué)藥品不負(fù)責(zé)任。務(wù)必將泵送流體的材料**數(shù)據(jù)表
(MSDS) 置于隨手可得 處。
?發(fā)運前已經(jīng)用水對所有泵做了預(yù)試驗，如果用戶泵送的材料會與水起反應(yīng)(即硫酸、聚合物), 應(yīng)卸下泵頭，徹底干燥。閥座、球形閥、密封墊和隔板也應(yīng)干燥。在投運泵前，應(yīng)嚴(yán)格遵守 本程序。
? 閥芯上應(yīng)壓印指示流體流向。安裝時一定要使箭頭朝著流量方向，從上到下閱讀標(biāo)記。
? 計量危險材料時，不要使用塑料管，嚴(yán)格地使用合適的剛性管。有關(guān)專用適配器或閥門組件 信息請咨詢供應(yīng)商。
?計量泵不可用于處理或計量易燃液體或材料。

PULSAtron Series E Plus Metering Pump

General Description
Pulsafeeder PULSAtron Series E Plus chemical metering pumps are positive displacement, diaphragm type pumps. Output volume is adjustable while pumps are in operation from zero to maximum capacity. The PULSAtron Series E Plus contains a highly reliable timing circuit as well as circuit protection against voltage and current upsets. This pump features solenoid protection by thermal overload with auto-reset. The Series E Plus guided check valves, with their state-of-the-art seat and ball designs, provide precise seating, and excellent priming and suction lift characteristics. Our timing circuit is highly reliable and, by design, virtually unaffected by temperature, EMI and other electrical disturbances.
Pump Controls
Adjustment is by means of readily accessible dial knobs, one for changing stroke length and the other for changing stroke frequency. Both knobs are located opposite the liquid handling end. Automatic control via 4-20mA DC and stop function inputs. Auto-Off-Manual switch.
Drive Assembly
The pump drive is totally enclosed with no exposed moving parts. Electronics are housed in chemical resistant enclosure at the rear of the pump for maximum protection against chemical spillage. Average electrical power consumption is 130 Watts.
Materials of Construction
See Specifications tab. Chemical metering pump housing shall be of chemically resistant PBT thermoplastic. All exposed fasteners are stainless steel. Valve seat and seal ring are renewable by replacing the cartridge valve assembly.
