Excavators turned sluggish troubleshooting method excavators, sharp turn often appear slow Symptom steering wheel in motion. The steering system works, it can determine this failure is due to the volumetric efficiency of the hydraulic steering system and the system pressure drops too low caused. The main reason is that it produces hydraulic systems, external leakage serious. In general, the following methods can be used to check and exclusion. If (1) Check the hydraulic external steering system for leaks. Description external leakage of the main symptoms are: hydraulic oil to greater losses, the system pressure drop prices used for small and medium excavators, steering cylinder and motor movement is not smooth, resulting in turn turned slow and weak, can not even turn. The main cause of external leakage are: tubing connector mismatch, poor sealing and hose rupture; seal mismatch, wear, aging or damage; high oil temperature, thereby increasing the leakage. When they find an external leak, should be timely maintenance. Quality and quantity (2) Check the hydraulic oil hydraulic oil will directly affect the working status of the steering system. Hydraulic oil is too small, it will pump oil supply shortage caused due to the machine's steering movements slow, it should add the hydraulic oil to the required level; when a foreign body in the hydraulic oil tank is not clean or impurities into the hydraulic system after It can cause seal damage or injury of the element with the deputy, the inner leakage increases, causing slow turn. To this end, on the oil hydraulic oil must be carefully checked. If the presence of impurities in the oil should be replaced hydraulic oil and clean the entire hydraulic system. Taian Jia and Heavy Machinery Co., Ltd. excavator hammer maintenance due hammers very poor working conditions for small and medium excavators, proper maintenance can reduce machine failure, prolong life of the machine, in addition to timely maintenance of the host, it should also note the following: (1) Visual inspection. Inspection of the bolts are loose; the connecting pin for excessive wear; check whether the drill rod bushing gap with their normal, if there is oil leaking therebetween, indicating low pressure seal is damaged, replace to professionals. (2) lubrication. Lubrication point domestic small and medium sized excavator working device, before the job and each successive 2 ~ 3h after operation, and should be lubricated. (3) the replacement of the hydraulic oil. Hydraulic oil change and vary depending on operating environment, a simple way to judge the quality of the oil is to observe the color of oil, when oil deterioration in the situation is extremely serious, the oil should be let go of small and medium agro-mining machine prices and clean the tank, and then inject the new oil filter. (4) the main breaker as set contains precision components hydraulic circulatory system, usually without special equipment factory Do not disassemble, repair commission must be made.泰安嘉 and Heavy Machinery Co., Ltd.
