SNS440R54U12.1W21三螺桿泵、SN系列潤(rùn)滑油泵

*、確定泵的轉(zhuǎn)速：（SN 系列螺桿泵的極限轉(zhuǎn)速為＜6000r.p.m）

First, determine the pump speed （the speed limit: SN series screw pump for the < 6000r.p.m）

1．泵轉(zhuǎn)速的選擇以輸送介質(zhì)的粘度和泵的規(guī)格確定轉(zhuǎn)速范圍，一般輸送高粘度介質(zhì)時(shí)，

Specifications to the transmission medium viscosity and pump 1 pump speed selection range of speed, general conveying high viscosity medium,

泵應(yīng)選低轉(zhuǎn)速；若粘度低，相應(yīng)選擇高轉(zhuǎn)速。

Low speed pump should be selected; if the viscosity is low, the corresponding selection of high speed.

對(duì)于大規(guī)格的泵（主桿外徑∮60mm 以上）

The specifications of the pump （above the main rod diameter, 60mm）

介質(zhì)粘度γ＞20°E 時(shí)，轉(zhuǎn)速以970rpm 或720rpm 為宜。

Medium viscosity γ > 20 ° E, speed to 970rpm or 720rpm is appropriate.

若γ＞80°E 如粘膠液，轉(zhuǎn)速可選n=200~500rpm

If gamma > 80 ° E such as viscose, speed optional n=200~500rpm

對(duì)于小規(guī)格的泵（主桿外徑∮60mm 以下）：

For small size pump （main rod diameter, below 60mm）:

γ＞20°E 時(shí)，n 選1450rpm 或970rpm.

Gamma > 20 ° E, n 1450rpm or 970rpm.

γ＞80°E 時(shí)，n 選300~600rpm。

Gamma > 80 ° E, n 300~600rpm.

2．由于泵的轉(zhuǎn)速愈高摩擦功率愈高，泵的磨損越大，壽命越短，如果輸送介質(zhì)的潤(rùn)滑

2 because the pump speed is higher friction power is higher, the greater the pump wear,short life, if the lubrication delivery medium

性較差，或含有微量雜質(zhì)，應(yīng)選較低轉(zhuǎn)速，使泵保持較長(zhǎng)的使用壽命。*n＜1450rpm

Poor, or contain trace impurities, should choose the low speed, long service life of the pump.Recommended n < 1450rpm

第二、結(jié)構(gòu)形式的選擇

Second, the choice of structure

結(jié)構(gòu)的選擇可根據(jù)泵的運(yùn)行環(huán)境和安裝環(huán)境，選擇合適的安裝形式并遵循以下的原則：

Structure selection according to the running environment of pump and the installation environment, choose to install the appropriate form and follow the following principles:

1． 輸送潤(rùn)滑性油類，且溫度T＜80℃時(shí)，選擇內(nèi)置軸承結(jié)構(gòu)的泵。

A 1 conveying lubricating oil, and the temperature of T < 80 ℃, the choice of built-in bearingstructure of pump.

2． 輸送潤(rùn)滑性較差，或溫度T＞80℃時(shí)，選擇外置軸承結(jié)構(gòu)的泵。

2 delivery of poor lubrication, or temperature T > 80 ℃, select the external bearing structure of pump.

3． 輸送流動(dòng)性差，粘度高的介質(zhì)或?qū)λ斔徒橘|(zhì)進(jìn)行加熱或保溫時(shí)，選雙層加熱泵體

3 the transport mobility is poor, high viscosity of medium or to transfer medium heating or insulation, choose double heating pump body

結(jié)構(gòu)的泵。

Structure of pump.

4． 輸送高溫介質(zhì)時(shí)，應(yīng)選擇耐高溫的材料制成的泵或局部冷卻的泵。

The 4 conveying high temperature medium, should choose the high temperature resistant material made of pump or local cooling pump.

5． 關(guān)于泵的吸入能力可查閱樣本。

5 on the pump suction capacity of the sample.

第三、泵材料組合的選擇 見上表

Third, pump materials portfolio selection see table

第四、泵的吸上能力

Fourth, the pump suction capacity

通過降低轉(zhuǎn)速或加熱降低介質(zhì)黏度的方法，可達(dá)到高的吸上性能，見NPAKP-SHR 表

By reducing speed or heating way of reducing medium viscosity, can achieve high onabsorbing properties, see table NPAKP-SHR

第五、配套電機(jī)的選配

Option fifth, matching motor

泵的型號(hào)選定后，根據(jù)樣本數(shù)據(jù)，可查到泵的軸功率N，該軸功率再加上一定的功率儲(chǔ)

The pump model is selected, based on sample data, can be found in the shaft power Npump, the shaft power coupled with a power storage

備后，作為選配電機(jī)的依據(jù)，一般電機(jī)功率Nm 不小于泵軸功率N 乘以功率儲(chǔ)備系數(shù)K 所

Later, as the basis for choosing motor, general motor power Nm is not less than the pump shaft power N multiplying power reserve coefficient K

得的值即：Nm≥K·N。K 值由下表查得。

That is worth it: Nm ≥ K · N. The K value from the table below check.
