三(sān)螺杆泵(bèng)水壓試驗hydrostatic test

   我廠在成品泵完成後，需要(yào)進(jìn)行水(shuǐ)壓試驗(yàn)，在進口法(fǎ)蘭(lán)處裝入(rù)端蓋(gài)，對于(yú)45b的三螺杆泵，通(tōng)入0.6mpa的(de)大氣壓，把整個成(chéng)品泵沉(chén)入水中，觀察(chá)是(shì)否有氣泡(pào)。得到泵體(tǐ)、後蓋(gài)、密封(fēng)壓蓋(gài)等零部件(jiàn)處是(shì)否因為鑄(zhù)件沙(shā)眼、密封不(bú)夠、螺絲松牙等(děng)原因漏氣。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(luó)杆泵(bèng)選泵要點(diǎn)optional pump points
    ①首先應(yīng)根據油(yóu)品的(de)粘度選擇适當的泵轉速(sù)，以保證(zhèng)泵的粘度能滿足用戶的(de)實際(jì)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(zhì)粘度v>760 /s，請與我廠聯系，我(wǒ)廠幫助用戶選(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(de)規格(gé)及相應粘度下(xià)的壓力流(liú)量後，可以(yǐ)查(chá)到泵的(de)配套(tào)電機(jī)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樣本(běn)安裝尺寸(cùn)均為卧式(shì)安裝(zhuāng)尺寸，若(ruò)需其餘(yú)形式安裝尺寸(cùn)請與(yǔ)我廠聯系(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(kè)戶的(de)實際需要(yào)設計特殊(shū)尺寸(cùn)。our factory can design according to customer's actual needs special size.
    ⑥三螺杆(gǎn)泵的進(jìn)口需(xū)加裝(zhuāng)過濾器，過濾器過流(liú)面積應為泵(bèng)進(jìn)口截面積(jī)的7～13倍(bèi)，過濾目(mù)數(shù)應為(wéi)：輕油80～100，潤滑(huá)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.
