大型挖沙船挖斗維修保養(yǎng)方法有哪些？

   挖沙船可分為單傳送挖沙船、雙傳送挖沙船、三傳送挖沙船、四傳送挖沙船，挖沙船的保養(yǎng)刻不容緩，有的客戶認為保養(yǎng)是件無所謂的事，其實不然，表面覺得保養(yǎng)沒有必要，如果長期進行保養(yǎng)，會使設備不容易老化，使用壽命時間長，對各個部件也要進行定期維護保養(yǎng)，有的客戶會進入誤區(qū)，在選擇潤滑油時，會認為用同一型號的，這是錯誤的，因為挖沙船的型號是不同的，所以在選擇潤滑油時，也要用不同型號的潤滑油，在保證質(zhì)量的前提下還要進行壓縮比和排量進行選擇，最后選出最適合自己挖沙船的潤滑油。那么，挖沙船挖斗是如何維修保養(yǎng)的。
  按時間來進行保養(yǎng)：
  每100H保養(yǎng)項目；動臂腳銷；動臂缸缸桿端；動臂、斗桿連接銷；斗桿缸缸桿端；挖斗缸缸頭銷軸；半桿連桿連接銷；動臂缸缸頭銷軸；斗桿、挖斗缸缸桿端；挖斗缸缸頭銷軸；斗桿缸缸頭銷軸；斗桿連桿連接銷；檢查回轉機構箱內(nèi)的油位（加機油）；從燃油箱中排出水和沉淀物。
  每250H保養(yǎng)項目；檢查終傳動箱內(nèi)的油位（加齒輪油）；檢查蓄電池電解液；更換發(fā)動機油底殼中的油，更換發(fā)動機濾芯；潤滑回轉支承（2處）；檢查風扇皮帶的張緊度，并檢查空調(diào)壓縮機皮帶的張緊度，并作調(diào)整。
  每500h保養(yǎng)項目；同時進行每100和250H保養(yǎng)項目；更換燃油濾芯；檢查回轉小齒輪潤滑脂的高度（加潤滑脂）；檢查和清洗散熱器散熱片、油冷卻器散熱片和冷疑器散熱片；更換液壓油濾芯；更換終傳動箱內(nèi)的油（僅首次在500h時進行，以后1000h一次）；清洗空調(diào)器系統(tǒng)內(nèi)部和外部的空氣濾芯；更換液壓油通氣口濾芯。
　以上是統(tǒng)一重工為您介紹的挖沙船挖斗的維修保養(yǎng)步驟，按照以上操作，相信您的挖沙船會越來越好，在使用過程中，如果發(fā)生故障，請不要焦躁，分析原因并找到解決方法。希望會對大家有幫助。

Large dredger bucket maintenance methods are there?
   Dredging vessels can be divided into single and double transfer transfer dredging vessels, dredgers dredging vessels, three transport four transfer dredging vessels, dredgers maintenance urgent, some customers think that maintenance is a matter of indifference, in fact, there is no need to feel the surface maintenance, if long-term maintenance, the equipment is not easy to aging, the use of the life time is long, the various components should be regular maintenance, some customers will enter the misunderstanding in the choice of lubricating oil, will think with the same type, this is wrong, because the dredging type is different, so in the choice of lubricating oil, lubricating oil should also use different types of. On the premise of ensuring the quality and compression ratio and flow rate were selected, the final selection of the most suitable for their own dredging lubricating oil. Then, the dredging bucket is how to repair and maintenance.
Maintenance by time:
   Each 100H maintenance projects; boom foot pin; boom cylinder rod end; the arm and the bucket rod connecting pin; the bucket rod bucket cylinder rod end; cylinder head pin; half rod connecting pin; the boom cylinder head pin; bucket rod and bucket cylinder rod end; bucket cylinder head pin; the bucket rod cylinder head pin; the bucket rod connecting pin; oil level check box rotating mechanism (with oil); water and sediment discharge from the fuel tank.
   Each 250H maintenance projects; final drive oil level check box (add gear oil); check the battery electrolyte; replace the engine oil pan oil filter replacement engine; lubricating rotary bearing (2); check fan belt tension, and check the air conditioning compressor belt tension, and make adjustments.
  Each 500h maintenance projects; at the same time every 100 250H and maintenance projects; fuel filter replacement; check rotary pinion grease height (grease); check and clean the radiator radiator, oil cooler heat sink and chiller heat sink; replacement of hydraulic oil filter replacement; final transmission box oil (only for the first time in 500h, 1000h a); air filter cleaning device of air conditioning system of internal and external; replacement of hydraulic oil vent filter.
   The above is to introduce you to the unified heavy dredging ship maintenance steps digging bucket, operate in accordance with the above, I believe your dredgingship will become better and better in the use process, if a failure occurs, please don't fret, analyze the causes and find solutions. I hope it will be helpful.
