Examples
- Surveying projection of over - head point amp; line using intersecting line of two vertical plane
垂面交线法悬点与悬线投影测量研究 - Analysis and research on the projection declination of horsehead ' s pendulous point of beam pumping unit
游梁式抽油机驴头悬点投影偏差的分析研究 - The calculation model can be used to optimize the structure and size of the rear horsehead , solve the problem that the structure and size of the rear horsehead affect the kinematic parameters of the polished rod and the torque factor , as well as the performance of the unusual shape beam pumping unit
利用此方法可以准确而迅速地求出不同机型的悬点位移、速度、加速度及扭矩因数等各项运动参数，也可计算优化后驴头的结构尺寸，解决异形游梁式抽油机后驴头结构与尺寸直接影响悬点的运动参数和扭矩因数，进而影响抽油机工作性能的问题。 - 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
