1. longerpump蠕动泵怎么计算流速

Danzel 演唱的歌曲《Pump It Up》

歌词:

Pump p p pump pump p p p pump

Pump p p pump pump it up

Pump p p pump pump p pump p pump

Pump p p pump pump it up

Pump p p pump pump it up

We gon do it like (Uuh, uuh, uuh)

Look, pump it up if you came to get it krunk

With a dame and shit that's drunk

You came to get it on, more than 5 O's in your bank

Then get it on, roll up like that stank

And get it on, slank that fitted on

Came to get it on

Hold up she want work that twork that

Then again let me hurt that murk that

Til you gotta hurt back

Can't spit it out, boo you gotta slurp that

Can't cuddle after we done, it wasn't worth that

Joey I'm responsible for bringin Jersey back (And we bad huh)

She at the bar stylin' she throwing it up

She drink a little hypno, throwing it up

But I'm only dealing with freaks that wanna cut

Ma if you agree I want nut

Camcorder, get it played late night on BET Uncut (uhh)

Fellas - do your thing let me do my thang

I mean - do your thing let me do my thang

Shorties - move that thing, mami move that thing

C'mon - move that thing, mami move that thing

Hustlers - do your thing let me do my thang

Please tell the DJ - pump p p pump pump it up!

I see some haters grilling

I see some ladies chilling

I see dat girlie

I been plottin to get

See can hop in the whip

And we can

Pump p p pump pump it up

OK we was leaving we was done

Then she said can my people's come

Here we go I see it don't stop

They wanna ride in something were the rims don't stop

Look baby you fine, but your girlfriends not

And then she wanna hold out getting cute on the phone

I ain't gotta be bothered, be cute on your own

My jump off doesn't run off at the mouth so much

My jump off never ask why I go out so much

My jump off never has me going out of my way

And she don't want nothing on Valentines Day

My jump off don't argue or get rebellious

And she don't mind hanging out wit da fellas

My jump off's not insecure or jealous

(Uuh, uuh, uuh)

chorus

x2

Y'all dudes keep talking bout your ice and all the shine to it

That's alright go cross-world find cubic

Ma wanna fall in love like I'm cupid

Telling me she don't give brain like I'm stupid

You can do anything if you put your mind to it

(Get it)

Think about it the game is bad playa

Ain't it bad playa

Don't worry Joey'll change it back playa

Might of heard me spittin wit Cain and Fab playa

I got the set boards to bring it back playa

Bang and clap playa

Front man no longer playin the back playa

Plain as that playa

808's pumpin bang the track playa

Want my 2nd wind change the rap playa

Jump off 1 man gang I'm back playa

Look, Want you want bump double click pump

Ride, ride swamp dump off homie jump off

All these haters on my (huh) won't jump off

When all the streets need is J J J Jump off

J J Jump J J J J J Jump off

Uuh, uuh, uuh

2. 蠕动泵速率

要弄明白这个问题,首先要了解蠕动泵是怎样产生压力的。

蠕动泵是靠滚轮挤压软管来输送液体,为了防止液体回流,必须一直保持密封性,有了密封性就相应的会产生一定的压力。那么压力的大小又是跟什么有关系呢?是跟压管压的松紧有关系,压管越松,压力越小,软管寿命越长,松到不密封的时候就没有压力了;相反,压管越紧,压力越大,紧到一定程度的时候就会对软管产生比较大的压管疲劳磨损,软管寿命也就会短。综上所述,蠕动泵的压力就是靠压管间隙来决定的,这就是为什么同一个型号的蠕动泵所适用的软管壁厚都一样了,内径和外径的大小不是关键,只要壁厚相同(滚轮够长)就可以使用同一款泵头。但是问题就来了,假如同样是2.4mm壁厚的软管,厂家和厂家之间,生产的软管肯定存在一定的误差,就算是同一个厂家生产的软管,也会有±0.1mm的误差,而对于蠕动泵的压力而言,这0.1mm的误差足以导致很大的压差,也就是说在压管间隙一定的情况下,软管不同,压力就会不同,相应的,软管寿命就会不同。在实际应用中,优秀的蠕动泵设计会设有压力调节的功能,以适应不同厂家,国产,进口泵管之间的尺寸差异。此项功能对于壁厚小于2.4mm的泵来说至关重要,因为很小的误差就会导致很大的压差。而此项功能的另一个应用就是可以用在需要不同压力的场合,通过压力的调节就可以实现了,当然这里的压力范围要在蠕动泵可以承受的范围之内。适用壁厚为2.4mm及以下的蠕动泵压力范围大概是0-0.25Mpa;适用壁厚为4.8mm及以上的蠕动泵压力范围大概是0-0.6Mpa。影响蠕动泵压力的主要因素就是软管的壁厚,壁厚越厚,软管的承压能力越大,所能达到的压力也就越大。

3. 蠕动泵精度

蠕动泵一般分为四个类型。

一:调速型蠕动泵

调速蠕动泵的特点是可以很好的控制蠕动泵的转速,控制流体的运输速度。蠕动泵上面有一个显示屏幕,可以显示泵的速度,并且蠕动泵不但可以调整泵的速度还可以控制它的转动方向等。

二:分配型蠕动泵

分配型的蠕动泵其实与流量型的非常相似。具有流量分配还可以控制输出等功能。

三:流量型的蠕动泵

流量型的蠕动泵与分配型的蠕动泵相似一些。可以控制蠕动泵的流体量的在小,可以智能的校准流量等等功能。

四:定制型的蠕动泵

定制型的蠕动泵它的特点是泵头是可以改变的,可以进行定做,这就是定制型蠕动泵的特点

4. 蠕动泵转速与流量参考表

1、用刻度尺测量出取压点到液面高度。

2、用计算公式计算出:p=ρgh(p是压强,ρ是液体密度,水的密度为1×复10^3kg/m^3,g是重力加速度取9.8 N/kg,h是取压点到液面高度)

将所有水管预留的出水口用堵头堵上,接上水表供水,持续48小时,看水管的各个连接处有无渗漏,如果没有就基本上能够保证水压是正常的。

5. longerpump蠕动泵使用方法

1、请使用与机器铭牌上一致的电源,否则将损害设备!

2、请勿自行拆装机壳和改造设备内部,否则会引起故障,甚者电击事故!

3、关于产品的维修事宜请与经销商或直接与本公司联系。

4、安装和拆卸泵管时,请关闭电源,不要靠近转动的滚轮部位,防止手指和衣物被卷入机械机构!

5、泵管可能发生破损引起液体外溢,请采取必要保护措施,定期检查泵管!

6、安装和拆卸外部控制装置,请务必关闭电源,防止损害设备!

7、再连接外控或通讯接口时,请切断电源!

8、请将机器的保护地与大地连接,否则会有触电的危险或电磁干扰!

9、蠕动泵管是耗材,使用很长时间后,应注意管材的磨损状况。

6. 蠕动泵流速计算方法

1、首先应检查电源是否接好

2、检查电源保险是否烧坏

3、装上保险 接通电源,看显示器是否正常,蠕动泵显示器正常,启动泵后电机工作但是泵头不转,则检查泵头滚轮是否工作,可将泵头拆卸,用手滑动滚轮,如有卡死现象则需更换滚轮轴心,启动泵后电机不工作则需返厂维修

4、泵头拆卸方法,拧掉泵头后面四个螺丝,泵头打开,将滚轮前方的黑块下按。

7. 泵的流速计算

1、功率计算方式:P = ρgQH/(n1n2)。

2、式中字母的含义:P --功率,W;ρ--水的密度,ρ=1000 kg/m^3;g--重力加速度,g=9.8m/s^2;Q--流量,m^3/s;H--扬程,m;n1--水泵效率;n2--电机效率。

3、例题:N=30x(200/3600)x9.81x1/0.8=20.44≈20(kW)。(即选配20kW的电机)
