  1. 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，並確定了改造的三個原則：一是保證整機的可靠性，使抽油機運轉平穩，振動噪音小，壽命長；二是力求降低生產成本，減少零部件製造，盡可能選用原來的通用件，捨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參數。
