  1、熔體泵運輸、存放時應輕拿輕放。到貨后如三個月內不安裝,應重新清洗軸封。起吊ZB-100CC以上系列的熔體泵時,應使用吊環螺釘。

  2.安裝前用測具檢查、調整泵座與電機傳動軸的同心度應確保熔體泵軸在工作時按訂貨時標明的方向旋轉,否則會引起輸入軸斷裂、泵體損壞。熔體泵安裝的底座要平整,并有足夠的強度和剛性。在螺栓均勻緊固的情況下,應保證輸入軸能無卡滯地均勻回轉。萬向聯軸器的安裝誤差應不超過其允許的偏差值,以免引起附加力,縮短軸的壽命。安裝中旋緊螺釘時用力要均勻。

  3.熔體泵在交貨前均經過嚴格的試運轉檢驗,各項指標符號要求,交貨后可以直接投入使用。無論那種規格的熔體泵啟動使用加載負荷時應低速(5rpm左右)運轉一段時間,待各軸承處充分潤滑后可加載運轉,緩慢的提升工作壓力,當整體運行狀況較為穩定后,則可逐步將泵及整個系統調整至正常的工藝速度與壓力。

  4.熔體泵在加載前,應先均勻預熱,溫升不得超過120度每小時。在泵沒有達到工作溫度前不要啟動泵,冷啟動是容易引起泵損壞的時候。

  5.對于采用填料密封形式的熔體泵,應及時調整密封壓蓋的位置,保證佳的密封狀態。對于采用螺旋密封的泵,如果需要使用冷卻水輔助密封,應在螺旋密封組件上安裝1/8或1/4NPT接頭,然后通上水源。對于小排量的泵不要讓冷卻水影響到泵體的加熱。

  1、You should be careful of transporting and storing melt pump. You should clean the shaft seal when you don’t install it within 3 month of arrival. Use rings screws when you lift melt pump of ZB-100 above series.

  2、Before installation, test with testing tools, adjust concentricity between pump seat and motor shaft. Ensure the melt pump shaft rotates in ordering indicated direction, otherwise that will cause input shaft rupture and the pump body damage. Mounting base of melt pump should be smooth and has enough intensity and rigidity. Under the holding down bolt with is tightened evenly, make sure the input shafts rotate evenly without clamping stagnation. Deviation of universal coupling installation shouldn’t exceed the allowing deviation in order to avoid causing additional force and shortening the shaft life. You should tighten the screws evenly during the installation.

  3、The melt pumps have past strict test-turn inspection, each indications meet the requirements, you can put them into use directly. Any kinds of melt pumps should run in low speed (about 5 rpm) when you start the pumps. When each bearing has sufficient lubrication the pump can have load operation and the working pressure can be improved slowly. When there is a steady running of the whole line, you can adjust the pump and the whole system into normal operation speed and pressure.

  4、 Before loading the pump, there should be a even preheating for the pump. The rising temperature shouldn’t exceed 120℃ (250℉) per hour. Don’t start pump before it reaches the operation temperature, cold start is the most likely time to damage the pump. For melt pump with packing seal form, you should adjust the position of the sealing gland promptly to make sure the best sealing condition.

  5、For melt pump with packing sealing form , you should adjust the position of  sealing cover to ensure the best sealing state. For melt pump with helical sealing form, if it is necessary to use cooling auxiliary seal, you should install 1/8 or 1/4 NPT joint on the helical sealing component, then connecting water. For the small delivery capacity pump, don’t let the cooling water influence the heating of pump body.
