目前各农场的机务修理方面,缺少水泵压力试验器的设备很多。往往在拖拉机进行大修时,引擎换上了新品缸筒,而缸筒与引擎体上阻水橡皮圈如没有严密的接合,等把机件都装好了,引擎一发动,水就从冷却系中漏到曲轴箱内,造成了返工,影响了耕作计划的完成,还报废新添机油。为了补救这个漏洞,可利用现有的条件,自制一种简单压力试验器。 Currently farm maintenance, the lack of pump pressure tester a lot of equipment. Often in the tractor overhaul, the engine put on a new cylinder, and the cylinder and the engine block waterproof rubber band, such as no tight engagement, so the parts are installed, the engine started, the water from the cooling system In the crankcase leakage, resulting in rework, affecting the completion of the farming plan, but also scrapped the new oil.
