經計算及散环簧压力試驗得知,新造二号緩冲器初压縮力达20～30吨左右。初压縮力过大,其害处甚多,不但降低緩冲器的敏感性,使較大动力直接传至車体,危及貨物安全,尤其是牲畜家禽的运輸,使押运人員工作环境恶劣,使机車牵引起动困难,而且装拆也不方便,給检修工作增加麻煩,过大压力粗装緩冲器也不安全。 After calculation and bulk ring spring pressure test that the new No. 2 buffer initial compressive force of 20 to 30 tons. Initial compressive force is too large, and its many disadvantages, not only reduce the sensitivity of the buffer, so that the greater power directly transmitted to the body, endangering the safety of goods, especially livestock and poultry transport, the escort staff working environment so poor Locomotive traction difficult to start, but also inconvenient loading and unloading, overhauling the work to increase trouble, excessive pressure rough buffer is not safe.
