我廠(chǎng)在成品泵完成後(hòu)，需要進行水壓試(shi)驗，在進口法蘭處(chu)裝入端蓋，對于45B的(de)三螺杆泵，通入0.6MPa的(de)大氣壓，把整個成(cheng)品泵沉入水中，觀(guān)察是否有氣泡。得(de)到泵體、後蓋、密封(feng)壓蓋等零部件處(chù)是否因為鑄件沙(shā)眼、密封不夠、螺絲(si)松牙等原因漏氣(qi)。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.

三螺杆泵選泵要(yao)點Optional pump points

①首先應根據油(you)品的粘度選擇适(shì)當的泵轉速，以保(bao)證泵的粘度能滿(man)足用戶的實際吸(xī)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介質粘度(du)V>760 /s，請與我廠聯系，我(wǒ)廠幫助用戶選泵(bèng)。 medium viscosity V > 760 / s, please contact our factory, our factory to help users choose the pump.

③從性能表中選定(ding)泵的規格及相應(ying)粘度下的壓力流(liú)量後，可以查到泵(bèng)的配套電機功率(lü)。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樣本安裝尺寸均(jun)為卧式安裝尺寸(cùn)，若需其餘形式安(an)裝尺寸請與我廠(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.

⑤我廠可根據(ju)客戶的實際需要(yào)設計特殊尺寸。Our factory can design according to customer's actual needs special size.

⑥三(sān)螺杆泵的進口需(xū)加裝過濾器，過濾(lü)器過流面積應為(wei)泵進口截面積的(de)7～13倍，過濾目數應為(wéi)：輕油80～100，潤滑油60～80目，重(zhòng)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.
