1、重慶升降機(jī)齒輪泵噪聲過(guò)大首先從外部檢查,，檢查油管,、泵的安裝架，機(jī)架是否松動(dòng),。若有松動(dòng),，必須固緊，否則將產(chǎn)生共振,，齒輪泵進(jìn)油管中有無(wú)空氣,。檢查方法是仔細(xì)聽運(yùn)轉(zhuǎn)部分的聲音，在結(jié)合部加一點(diǎn)油,，若聲音變小,，說(shuō)明此處密封不好，漏氣,，應(yīng)擰緊接頭或更換襯墊．密封圈和接頭等,。
Hangzhou lifting platform first gear pump excessive noise from external inspections of pipeline, pump mount rack is loose. If loose, must be tightened, or they will have a resonance, presence or absence of a gear pump air into the pipeline. Listen carefully to the sound check is part of the operation, add a little oil at the junction, if the sound becomes small, indicating that the seal is not good here, leak, should tighten the fittings or replace gaskets. Seals and joints.

2、檢查升降平臺(tái)油箱液面是否達(dá)推薦值,，進(jìn)油管口是否始終低于液面,，否則向油箱加油，油液粘度過(guò)高,。油液應(yīng)該按齒輪泵使用說(shuō)明書上的要求選用,，并檢查在工作溫度下的粘度。
Check the tank level Hangzhou lifting platform is up to the recommended value, the intake pipe mouth is always lower than the level, otherwise the fuel tank, the oil viscosity is too high. Oil should be based on the requirements of the specification on the gear pump selection and check the viscosity at operating temperature.

3,、升降平臺(tái)泵進(jìn)油管口徑太小,。檢查流速不超過(guò)l．2-1．5米/秒，回油管布局不當(dāng),。在低液面時(shí),，回流產(chǎn)生渦流，帶有氣泡,，應(yīng)加足油液,，調(diào)整同油管位蹬。
Hangzhou lifting platform pump inlet pipe diameter is too small. Check the flow rate of no more than l. 2-1.5 m / s, improper return pipe layout. At low liquid level, flow generating vortex with bubbles, should add a little oil, adjust the pedal position with tubing.

4,、檢查升降平臺(tái)齒輪泵進(jìn)油管路的過(guò)濾器上是否有臟物,，排除力法是用油沖洗掉臟物，從泵軸密封處或泵體泵蓋接合處滲入空氣,?？梢愿鼡Q油封或紙墊,，由于液壓油中的塵埃、異物進(jìn)入齒輪泵,，使齒輪泵一部分受損,，需要更換被損零件。
Hangzhou lifting gear check if there is dirt on the platform pump inlet line filter to exclude force method is to flush out dirt oil from the pump shaft seal or pump air pump cover joints infiltration. You can replace the seal or pad of paper, as a result of the hydraulic oil in the dust, foreign matter into gear pumps, gear pumps damaged part needs to be replaced was damaged parts.

5,、升降平臺(tái)齒輪泵零件松動(dòng)。必須將松動(dòng)零件擰緊,，齒輪精度低,，在嚙合時(shí)產(chǎn)生噪聲，需更換高精度齒輪,。
Hangzhou lifting platform pump gear loose parts. Loose parts must be tightened, low gear precision noise when engaged, to be replaced with high precision gears.
