英文: 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 reliab
中文: 文摘:针对LCJ1250气平衡式链条抽油机存在气平衡故障率高和现场维修困难等问题,提出将气平衡改造成工作可靠的重力平衡的方案,并确定了改造的三个原则:一是保证整机的可靠性,使抽油机运转平稳,振动噪音小,寿命长;二是力求降低生产成本,减少零部件制造,尽可能选用原来的通用件,舍去平衡缸和空气包等气平衡附件,在原往返架主体上悬挂一个配重箱;三是力求不改变冲程、冲次及最大悬点载荷等主要技术参数。
