氣動(dòng) 隔膜泵是 本公司開發(fā)的第 三代氣動(dòng)隔膜泵， 具有使用壽命長(zhǎng)，不會(huì)停頓等優(yōu)點(diǎn)，它既能抽送流動(dòng)的液
體，又能輸送一些不易流動(dòng)的介質(zhì)，具有自吸泵、潛水泵、 屏蔽泵、泥漿泵和雜質(zhì)泵等輸送機(jī)械的許多優(yōu)點(diǎn)。 、不需灌引水，吸程高達(dá) ，揚(yáng)程達(dá) ，出口壓力
≥ ； 、流動(dòng)寬敞，通過性能好，允許通過最大顆粒直徑達(dá) 。抽送泥漿、雜質(zhì)時(shí)，對(duì)泵磨損甚微； 、揚(yáng)程、流量可通過 氣閥開度實(shí)現(xiàn)無級(jí)調(diào)節(jié) 氣 壓調(diào)
節(jié)在 之間 ； 、該 泵無旋轉(zhuǎn)部件， 沒有 軸封， 隔膜 把抽 送的介質(zhì)
與泵的運(yùn)動(dòng)部件、工作介質(zhì)完全隔開，所輸送的介質(zhì)不會(huì)
向外泄漏。所以抽送有毒、易揮發(fā)或腐蝕性介質(zhì)時(shí)，不會(huì)
造成環(huán)境污染和危害人身安全； 、不必用電，在易燃、易爆場(chǎng)所使用安全可靠； 、可以浸沒在介質(zhì)中工作； 、使 用方便、工作可 靠、 開停只 需簡(jiǎn) 單地 打開和關(guān)
閉氣體閥門，即使由于意外情況而長(zhǎng)時(shí)間無介質(zhì)運(yùn)行或突
然停機(jī)泵也不會(huì)因此而損壞，一旦超負(fù)荷，泵會(huì)自動(dòng)停機(jī)， 具有自我保護(hù)性能，當(dāng)負(fù)荷恢復(fù)正常后，又能自動(dòng)啟動(dòng)運(yùn)
行； 、結(jié)構(gòu)簡(jiǎn)單、易損件少，該泵結(jié)構(gòu)簡(jiǎn)單，安裝、維修
方便，泵輸送的介質(zhì)不會(huì)接觸到配氣閥，聯(lián)桿等運(yùn)動(dòng)部件， 不象其他類型的泵因轉(zhuǎn)子、活塞、齒輪、葉片等部件的磨
損而使性能逐步下降； 、可輸送較粘的液體 粘度在 萬厘泊以下 ； 、本泵無須用油潤(rùn)滑，即使空轉(zhuǎn)，對(duì) 泵也無任何影
響，這是該泵最大特點(diǎn)。
PERFORMANCE SUMMARY
QBK is new dev eloped air op erated diaphragm s eries of our?
company which the third generation, it has the virtue of long service
lif e and nonsto p ope ration, not only it can convey s ome u neasy
fl owed medium, with the merits of self-priming pump, submersible
pump, shield pump, slurry pump and impurity pump etc.?
1. It`s unnecessary to pour the drawing wa ter, the suction lift?
re aches 5m he ight, the deli very l ift reac hes 70m len gth an d the
export pressure 6bar.?
2. Wide flow and good performance. The diameter allowed to
pass the max g rain reaches 10mm. The damage is very less to the
pump while exhausting the slurry and impurity.?
3. The delivery lift and flow can pass the pneumatic valve open
to realize the step less adjustment(the pneumatic pressure adjustment?
is between 1-7bar).?
4. This pump ha s no ro tary parts and no b earing seals. The
diaphragm will completely separate the exhausted medium and pump
ru nning parts, workin g med ium. The conveyed medium can `t be
leaked outside. Thus it will not cause the environmental pollution
an d human bod y safe ty dangerous while exhau sting the toxin and
flammable or corrosive medium.?
5. No electricity. It`s safe and reliabl e while using in the flam-? mable and explore places.?
6. It can be soaked in medium.?
7. It`s con venien t to us e and reliabl e to work. Only op en or?
close the gas valve body while starting or stopping. Even if n o me-?
dium operation or pausing suddenly for long time because of accident? matters, the pump will not b e damaged ca used by this. Once over-?
lo ading, the pump wi ll automatica lly sto p and possesses th e self?
protection func tion. When the load recov ers no rmally, it als o can
st art automatically.?
8. Simple structure and less wearing parts. This pump is simple
in structure, installation and maintenance. The medium convey ed by
the pump will not touch the matched pneumatic valve and coupling
le ver etc . Not like other kin ds pumps, th e performance will drop
down gradually because of the damages of rotor, gear and vane etc.?
9. It can tr ansmit the a dhesiv e liqui d (the viscosity is below?
10000 centipoises).?
10. This pump ne edn`t the oil lubric ant. Even if idling, it has?
any influence to the pump. This is a characteristic of this pump.?
