船用泵 ( 船檢齒輪泵,船檢螺桿泵) 常見的故障及解決方法 Marine pump (ChuanJian gear pump, ChuanJian screw pump) common fault and the solving methods

    船用泵 ( 船檢齒輪泵 , 船檢螺桿泵 ) 常見故障有四種，解決方法也簡(jiǎn)單。 Marine pump (ChuanJian gear pump, ChuanJian screw pump) there are four common faults, the solution is simple.

一、無壓差 A, no pressure difference

　　（ 1 ）船用泵 ( 船檢齒輪泵 , 船檢螺桿泵 ) 轉(zhuǎn)向不對(duì)，核對(duì)轉(zhuǎn)向； (1) Marine pump (ChuanJian gear pump, ChuanJian screw pump) to wrong, check steering;

　　（ 2 ）介質(zhì)臟葉片被卡主：撥動(dòng)傳動(dòng)軸，正反轉(zhuǎn)幾圈讓泵內(nèi)葉片活動(dòng)一下，仍不上壓，則拆泵檢查； ) medium dirty blade stuck the Lord: toggle drive shaft, positive &negative laps let pump blade activities once, is still not on the pressure, the open pump inspection;

　　（ 3 ）吸入管漏氣：檢查并消除漏氣現(xiàn)象； (3) the suction pipe leak: check and remove air leakage phenomenon;

　　（ 4 ）吸入管氣體不能從出口排出：檢查各閥門，開啟出口管路，使氣體從出口排出； (4) the suction pipe gas can't from export discharge: check the valve and open the export pipeline, make gas from export discharge;

二、工作壓力達(dá)不到 Second, the working pressure can not reach

　　（ 1 ）轉(zhuǎn)速太低。適當(dāng)提高轉(zhuǎn)速；（ 3 ）船用泵 ( 船檢齒輪泵 , 船檢螺桿泵 ) 地腳松動(dòng)，緊固油泵地腳螺栓； speed is too low. An appropriate increase in speed;

　　（ 2 ）密封大量泄漏，先檢查軸承是否損壞，若未壞，在檢查油封并更換； seal a large number of leakage, check if the bearing damage, if not bad, in check oil seal and replace;

　　（ 3 ）安全閥開啟壓力過低，調(diào)整安全閥栓達(dá)到要求壓力； the relief valve opening pressure too low, adjust the relief valve bolt meet requirement pressure;

　　（ 4 ）油泵內(nèi)部損失過大，船用泵 ( 船檢齒輪泵 , 船檢螺桿泵 ) 的主要零件如：泵體偏心套、端蓋、轉(zhuǎn)子、葉片等磨損過大則更換零件； pump internal loss is too large, Marine pump (ChuanJian gear pump, ChuanJian screw pump) of main parts such as: pump body eccentric sleeve, end cover, rotor, leaf and excessive wear the replacement parts;

三、震動(dòng)和噪音 Three, vibration and noise

　　（ 1 ）軸承損壞，更換軸承； bearing damaged, replace bearing;

　　（ 2 ）泵軸心與傳動(dòng)軸不同心，偏移太大，調(diào)整泵軸與傳動(dòng)軸同心度，使傾斜角度不得大于 7 度； the pump shaft axis and different heart, migration is too big, adjust the pump shaft and shaft concentricity, tilt Angle must not be more than 7 degrees;

　　（ 4 ）偏心套磨損太大，更換偏心套； Marine pump (ChuanJian gear pump, ChuanJian screw pump) anchor, become loose, fastening pump anchor bolt,

四、雙聯(lián)油泵變化困難，齒合不上 eccentric sleeve wear too big, change eccentric sleeve;

　　（ 1 ）氣壓太低或電磁氣閥失靈，提高氣壓或更換電磁氣閥； Four, double pump change difficulties, tooth close in

　　（ 2 ）軟軸拉線脫落或不靈活，調(diào)整和潤滑或更換。

(1) pressure too low or electromagnetic valve failure, improve the pressure or replace electromagnetic valve;

(2) flexible shaft pull off or not flexible, adjustment and lubrication or replacement.
