三螺(luó)杆泵水(shui)壓試驗(yan)Hydrostatic test 我廠在(zài)成品泵(bèng)完成後(hòu)，需要進(jin)行水壓(ya)試驗，在(zài)進口法(fa)蘭處裝(zhuāng)入端蓋(gài)，對于45B的(de)三螺杆(gǎn)泵，通入(rù)0.6MPa的大氣(qì)壓，把整(zhěng)個成品(pǐn)泵沉入(ru)水中，觀(guān)察是否(fou)有氣泡(pao)。得到泵(beng)體、後蓋(gài)、密封壓(yā)蓋等零(líng)部件處(chù)是否因(yin)為鑄件(jiàn)沙眼、密(mi)封不夠(gòu)、螺絲松(sōng)牙等原(yuan)因漏氣(qì)。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(gan)泵選泵(bèng)要點Optional pump points ①首(shou)先應根(gen)據油品(pin)的粘度(dù)選擇适(shì)當的泵(beng)轉速，以(yi)保證泵(bèng)的粘度(du)能滿足(zú)用戶的(de)實際吸(xī)入條件(jian)。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(zhān)度V>760 /s，請與(yǔ)我廠聯(lián)系，我廠(chang)幫助用(yòng)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(néng)表中選(xuan)定泵的(de)規格及(ji)相應粘(zhān)度下的(de)壓力流(liú)量後，可(kě)以查到(dao)泵的配(pèi)套電機(ji)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(yang)本安裝(zhuāng)尺寸均(jun)為卧式(shì)安裝尺(chi)寸，若需(xū)其餘形(xing)式安裝(zhuāng)尺寸請(qǐng)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(wǒ)廠可根(gen)據客戶(hù)的實際(jì)需要設(shè)計特殊(shū)尺寸。Our factory can design according to customer's actual needs special size. ⑥三(san)螺杆泵(bèng)的進口(kou)需加裝(zhuāng)過濾器(qì)，過濾器(qi)過流面(mian)積應為(wei)泵進口(kou)截面積(jī)的7～13倍，過(guo)濾目數(shu)應為：輕(qing)油80～100，潤滑(huá)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. |
