三螺(luo)杆泵水壓試驗(yàn)Hydrostatic test 我廠在成品泵(bèng)完成後，需要進(jìn)行水壓試驗，在(zai)進口法蘭處裝(zhuāng)入端蓋，對于45B的(de)三螺杆泵，通入(rù)0.6MPa的大氣壓，把整(zheng)個成品泵沉入(rù)水中，觀察是否(fǒu)有氣泡。得到泵(bèng)體、後蓋、密封壓(ya)蓋等零部件處(chù)是否因為鑄件(jiàn)沙眼、密封不夠(gou)、螺絲松牙等原(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. 三螺杆(gǎn)泵選泵要點Optional pump points ①首(shǒu)先應根據油品(pǐn)的粘度選擇适(shì)當的泵轉速，以(yǐ)保證泵的粘度(du)能滿足用戶的(de)實際吸入條件(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V>760 /s，請與(yǔ)我廠聯系，我廠(chang)幫助用戶選泵(beng)。 medium viscosity V > 760 / s, please contact our factory, our factory to help users choose the pump. ③從性能表中選(xuǎn)定泵的規格及(ji)相應粘度下的(de)壓力流量後，可(ke)以查到泵的配(pei)套電機功率。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(yàng)本安裝尺寸均(jun)為卧式安裝尺(chi)寸，若需其餘形(xíng)式安裝尺寸請(qing)與我廠聯系。 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)廠可根據客戶(hu)的實際需要設(shè)計特殊尺寸。Our factory can design according to customer's actual needs special size. |
