三螺(luo)杆泵水壓試(shi)驗Hydrostatic test 我廠在成(cheng)品泵完成後(hou)，需要進行水(shui)壓試驗，在進(jin)口法蘭處裝(zhuang)入端蓋，對于(yu)45B的三螺杆泵(bèng)，通入0.6MPa的大氣(qi)壓，把整個成(cheng)品泵沉入水(shui)中，觀察是否(fou)有氣泡。得到(dao)泵體、後蓋、密(mì)封壓蓋等零(ling)部件處是否(fǒu)因為鑄件沙(sha)眼、密封不夠(gou)、螺絲松牙等(děng)原因漏氣。I plant after completion of the finished product pump, water pressure test is required, at the inlet flange at the load end cover, three screw pump for 45 b, ventilation with atmospheric pressure of 0.6 MPa, the entire finished product pump submerged in the water, observe whether there is a bubble.Get the pump body, back cover, gland and other parts to inquire whether because the casting trachoma, seal is not enough, due to reasons such as flat screw loose teeth. 三(sān)螺杆泵選泵(bèng)要點Optional pump points ①首先應(ying)根據油品的(de)粘度選擇适(shi)當的泵轉速(su)，以保證泵的(de)粘度能滿足(zu)用戶的實際(jì)吸入條件。the first select the appropriate pump speed should be based on the viscosity of the product, to ensure that the viscosity of the pump can satisfy the user's actual suction conditions. ②介(jiè)質粘度V>760 /s，請與(yu)我廠聯系，我(wo)廠幫助用戶(hù)選泵。 medium viscosity V > 760 / s, please contact our factory, our factory to help users choose the pump. ③從性能(néng)表中選定泵(beng)的規格及相(xiang)應粘度下的(de)壓力流量後(hou)，可以查到泵(bèng)的配套電機(jī)功率。Selected in the table (3) from the performance of the specifications of the pump and the corresponding viscosity under pressure flow, you can check the pump motor power. ④樣本安(ān)裝尺寸均為(wei)卧式安裝尺(chi)寸，若需其餘(yu)形式安裝尺(chǐ)寸請與我廠(chang)聯系。 the installation size of samples for horizontal installation size, if you need the rest of the installation dimensions form please contact with our factory.  ⑥三螺杆泵的(de)進口需加裝(zhuang)過濾器，過濾(lǜ)器過流面積(jī)應為泵進口(kou)截面積的7～13倍(bei)，過濾目數應(yīng)為：輕油80～100，潤滑(hua)油60～80目，重油40目(mù)。 pump imports to be equipped with filter, filter over-current area shall be the pump inlet area of 7 ~ 13 times, filter mesh should be followed: light oil 80 ~ 100, 60 ~ 80 mesh of lubricating oil, heavy oil 40 mesh. |
