三螺(luó)杆泵水壓(yā)試驗Hydrostatic test 我廠(chang)在成品泵(bèng)完成後，需(xu)要進行水(shuǐ)壓試驗，在(zài)進口法蘭(lan)處裝入端(duān)蓋，對于45B的(de)三螺杆泵(beng)，通入0.6MPa的大(dà)氣壓，把整(zheng)個成品泵(bèng)沉入水中(zhong)，觀察是否(fou)有氣泡。得(de)到泵體、後(hòu)蓋、密封壓(ya)蓋等零部(bu)件處是否(fǒu)因為鑄件(jian)沙眼、密封(fēng)不夠、螺絲(si)松牙等原(yuan)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. ①首(shou)先應根據(ju)油品的粘(zhān)度選擇适(shì)當的泵轉(zhuan)速，以保證(zheng)泵的粘度(dù)能滿足用(yong)戶的實際(jì)吸入條件(jiàn)。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介質粘度(du)V>760 /s，請與我廠(chǎng)聯系，我廠(chǎng)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(xing)能表中選(xuan)定泵的規(guī)格及相應(yīng)粘度下的(de)壓力流量(liàng)後，可以查(chá)到泵的配(pei)套電機功(gōng)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(an)裝尺寸均(jun1)為卧式安(an)裝尺寸，若(ruò)需其餘形(xing)式安裝尺(chǐ)寸請與我(wo)廠聯系。 the installation size of samples for horizontal installation size, if you need the rest of the installation dimensions form please contact with our factory.  ⑤我(wo)廠可根據(jù)客戶的實(shí)際需要設(shè)計特殊尺(chǐ)寸。Our factory can design according to customer's actual needs special size. ⑥三螺杆(gan)泵的進口(kǒu)需加裝過(guò)濾器，過濾(lǜ)器過流面(mian)積應為泵(bèng)進口截面(miàn)積的7～13倍，過(guo)濾目數應(yīng)為：輕油80～100，潤(run)滑油60～80目，重(zhong)油40目。 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. |
