H3LB-25西安磨床螺桿泵 外圓磨床冷卻泵 高壓三螺桿泵
H3LB-25 Xi'an grinding machine screw pump external cylindrical grinding machine cooling pump high pressure three screw pump
三螺桿泵的主動(dòng)螺桿由電機(jī)驅(qū)動(dòng),主、從桿之間沒有機(jī)械接觸，由所輸壓力液體驅(qū)使從桿繞軸芯自轉(zhuǎn)，主、從桿之間，螺桿與泵套之間皆有一層油膜保護(hù)，因而泵的機(jī)械摩擦極小，壽命長。所輸送液體在泵內(nèi)做軸向勻速直線運(yùn)動(dòng)，保證了泵的噪聲低，振動(dòng)小。使輸送液體連續(xù)無脈地流動(dòng)。
Three screw pump driven by the motor drive, the main, from a mechanical contact between the rod, driven by the transmission of the pressure from the shaft around the core shaft rotation, the main, from the rod, between the pump and the pump casing is a layer of oil film protection, so the pump's mechanical friction is very small, long life. The delivery of liquid in the pump to do the axial uniform straight line motion, to ensure that the pump noise is low, small vibration. To flow continuously without a pulse.

一、螺桿泵的轉(zhuǎn)速選用 MA1420A上海第三機(jī)床廠H3LB-25磨床外圓磨螺桿泵
First, the choice of screw pump speed
螺桿泵的流量與轉(zhuǎn)速成線性關(guān)系，相對(duì)于低轉(zhuǎn)速的螺桿泵，高轉(zhuǎn)速的螺桿泵雖能增加了流量和揚(yáng)程，但功率明顯增大，高轉(zhuǎn)速加速了轉(zhuǎn)子與定子間的磨耗，必定使螺桿泵過早失效，而且高轉(zhuǎn)速螺桿泵的定轉(zhuǎn)子長度很短，極易磨損，因而縮短了螺桿泵的使用壽命。
Screw pump flow and speed into a linear relationship, with low speed screw pump, high speed screw pump can increase the flow and head, but the power increased significantly, high speed to speed up the wear between the rotor and the stator, the screw pump must be premature failure, and high speed screw pump stator rotor length is very short, easy to wear, and thus shorten the service life of the screw pump.
通過減速機(jī)構(gòu)或無級(jí)調(diào)速機(jī)構(gòu)來降低轉(zhuǎn)速，使其轉(zhuǎn)速保持在每分三百轉(zhuǎn)以下較為合理的范圍內(nèi)，與高速運(yùn)轉(zhuǎn)的螺桿泵相比，使用壽命能延長幾倍。
Through the reduction mechanism or stepless speed regulation mechanism to reduce the speed, so that its speed is kept at three hundred revolutions per minute in a reasonable range, compared with the high-speed operation of the screw pump, the service life can be extended several times.
二、螺桿泵的品質(zhì)
Two, the quality of the screw pump
螺桿泵的種類較多，相對(duì)而言，進(jìn)口的螺桿泵設(shè)計(jì)合理，材質(zhì)精良，但價(jià)格較高，服務(wù)方面有的不到位，配件價(jià)格高，訂貨周期長，可能影響生產(chǎn)的正常運(yùn)行。
Types of screw pump more, relatively speaking, the import of screw pump design is reasonable, excellent material, but the price is higher, some of the service is not in place, parts price is high, the order cycle is long, may affect the normal operation of the production.
國內(nèi)生產(chǎn)的大都進(jìn)口產(chǎn)品，產(chǎn)品質(zhì)量良莠不齊，在選用國內(nèi)生產(chǎn)的產(chǎn)品時(shí)，在考慮其性價(jià)比的時(shí)候，選用低轉(zhuǎn)速，長導(dǎo)程，傳動(dòng)量部件材質(zhì)優(yōu)良，額定壽命長的產(chǎn)品。
Most of the domestic production of generic imported products, product quality varies greatly, in the selection of the domestic production of products, in considering the price, choose low speed, long course, high transmission capacity component material, rated long life products.
三、確保雜物不進(jìn)入泵體
Three, to ensure that the debris does not enter the pump body
濕污泥中混入的固體雜物會(huì)對(duì)螺桿泵的橡膠材質(zhì)定子造成損壞，所以確保雜物不進(jìn)入泵的腔體是很重要的，很多污水廠在泵前加裝了粉碎機(jī)，也有的安裝格柵裝置或?yàn)V網(wǎng)，阻擋雜物進(jìn)入螺桿泵，對(duì)于格柵應(yīng)及時(shí)清撈以免造成堵塞。
Wet sludge mixed with the solid debris will cause damage to the screw pump rubber stator, so to ensure that debris does not enter the pump cavity is very important, a lot of sewage plant in the installation of the pump before, but also some of the installation grille device or filter, blocking debris into the screw pump, the grille should be timely cleaning so as not to cause blockage.
