1.液压泵输出流量不足液压泵输出流量不足的具体原因及检测方法如下;一是液压泵内泄漏过大;此时应检修或更换液压泵。二是带动液压泵工作的原动机转速过低;此时应将原动机转速提高到额定值。三是液压油箱内油液不足;此时应及时添加液压油至规定范围内。四是吸油滤油器堵塞;此时应及时清洗或更换吸油滤油器。五是吸油管漏油或液压泵吸油口密封不
1. The hydraulic pump output flow less than the hydraulic pump output flow shortages of the specific reasons and testing methods are as follows; First, excessive leakage within the hydraulic pump; at this time should repair or replace the hydraulic pump. Second, the prime mover driven hydraulic pump speed is too low; this time should be the prime mover speed increased to the rated value. Third, the lack of fluid within the hydraulic tank; this time should be added to the specified range of hydraulic oil. Fourth, oil filter plugging; this time should be promptly cleaned or replaced oil filter. Fifth, oil suction pipe or hydraulic pump suction port seal is not
