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,核對轉(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:撥動傳動軸,正反轉(zhuǎn)幾圈讓泵內(nèi)葉片活動一下,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,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 )泵軸心與傳動軸不同心,偏移太大,調(diào)整泵軸與傳動軸同心度,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.
