1.挂挡后不能立即行走1台TY160型推土机在启动发动机准备作业时,出现挂档后不能立即行走的故障。但在发动机运转3～5min后,或者从变速油路细滤器测压口进行人工排气后可以行走,且行走后工作正常。此故障的根源可能是变速泵吸空,使油压建立不及时,即变速泵吸油油路中有空气,导致变速泵
1. After the gear can not be immediately walked a Taiwan TY160 bulldozer to start the engine ready to work, there after hanging gear can not immediately walk the fault. However, it can be walked after the engine is run for 3 to 5 minutes, or after artificial exhaust from the fine oil pressure gauge of the variable speed oil line, and it works normally after walking. The root cause of this failure may be variable speed pump suction empty, so that the hydraulic pressure is not established in time, that is, there is air in the variable speed pump oil absorption circuit, resulting in variable speed pump
