三(sān)螺杆泵水(shuǐ)壓試驗hydrostatic test

   我廠在成品(pǐn)泵完成後，需要進行水壓試驗(yàn)，在進口法蘭處裝入端蓋，對于(yú)45b的三螺杆泵，通(tōng)入0.6mpa的(de)大氣壓，把(bǎ)整個成品(pǐn)泵沉(chén)入水中，觀察(chá)是(shì)否有氣泡。得到(dào)泵體、後蓋、密封壓蓋等零部件處是否因為鑄(zhù)件沙(shā)眼、密封不夠、螺絲(sī)松(sōng)牙等(děng)原因漏(lòu)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(luó)杆泵選泵要點(diǎn)optional pump points
    ①首先應(yīng)根(gēn)據油(yóu)品的粘度(dù)選擇适當的泵(bèng)轉速，以保證泵的粘(zhān)度能滿足(zú)用戶(hù)的實(shí)際吸(xī)入條(tiáo)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(zhān)度(dù)v>760 /s，請與我(wǒ)廠聯(lián)系，我(wǒ)廠幫助(zhù)用戶選(xuǎn)泵。 medium viscosity v > 760 / s, please contact our factory, our factory to help users choose the pump.
    ③從(cóng)性能表中(zhōng)選定泵的規格及相應粘度下(xià)的壓力(lì)流量後(hòu)，可以查(chá)到泵的(de)配套電機功率(lǜ)。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(zhuāng)尺寸(cùn)均為卧式安裝尺寸(cùn)，若(ruò)需其餘形式安裝尺寸請與(yǔ)我廠(chǎng)聯系(xì)。 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(gēn)據客戶的實際需要(yào)設計特殊尺寸(cùn)。our factory can design according to customer's actual needs special size.
    ⑥三螺(luó)杆泵(bèng)的進口需加(jiā)裝(zhuāng)過濾器，過(guò)濾(lǜ)器過流(liú)面積應(yīng)為泵進口截面(miàn)積(jī)的7～13倍(bèi)，過濾目數應為：輕油(yóu)80～100，潤滑油60～80目(mù)，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.
