例句與造句
- In the light of the problems of the air balance system of model lcj1250 chain drive pumping unit , it is proposed to change the air balance with counterweight balance , and three criteria for the modification is put forward : ( 1 ) ensuring the reliability of the unit with smooth operation , low noise and long life ; ( 2 ) cutting down the production cost and using less component parts as possible ; ( 3 ) carrying out modification without such main technical parameters as stroke , pumping speed and maximum polished rod load
針對lcj1250氣平衡式鏈條抽油機存在氣平衡故障率高和現(xiàn)場維修困難等問題，提出將氣平衡改造成工作可靠的重力平衡的方案，并確定了改造的三個原則：一是保證整機的可靠性，使抽油機運轉(zhuǎn)平穩(wěn)，振動噪音小，壽命長；二是力求降低生產(chǎn)成本，減少零部件制造，盡可能選用原來的通用件，舍去平衡缸和空氣包等氣平衡附件，在原往返架主體上懸掛一個配重箱；三是力求不改變沖程、沖次及最大懸點載荷等主要技術(shù)參數(shù)。 - Abstract : in the light of the problems of the air balance system of model lcj1250 chain drive pumping unit , it is proposed to change the air balance with counterweight balance , and three criteria for the modification is put forward : ( 1 ) ensuring the reliability of the unit with smooth operation , low noise and long life ; ( 2 ) cutting down the production cost and using less component parts as possible ; ( 3 ) carrying out modification without such main technical parameters as stroke , pumping speed and maximum polished rod load
