Examples
- 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
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。 - 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
