The excavator holding up is a troublesome problem for many operators. First of all, the fault point is not clear, and the problem cannot be solved quickly. Therefore, most of the time, people will choose to preliminarily check the conventional causes and components, and thoroughly overhaul the excavator until the gap between the engineering activities is reached. This practice actually does great harm to the machine! Small problems may turn into major failures! Today, Master Li, who repaired the Komatsu excavator, shared with you the problem of holding up the excavator!
1. First of all, the engine may cause car hold up: -- the fuel circuit, gas circuit, injection pump, fuel shut-off valve, the fuel circuit is blocked, and the fuel supply of the injection pump is insufficient.
2. Then the hydraulic pressure is also one of the problems of car holding: -- NCV valve element is stuck, the bypass valve is blocked, and the electro-hydraulic junction part fails
3. Second, supercharger: of course, insufficient intake of the engine will also induce car hold up. The reasons for insufficient air intake of the engine are: the supercharger does not work completely due to the blockage of the air filter element; The supercharger is worn; The air leakage of the exhaust branch pipe decreases. At the same time, check whether the small oil pipe connecting the engine block to the supercharger is smooth.
4. Parts wear and aging: some parts are also the most easily ignored by many excavator owners when they check the car, such as parts wear and aging. In this case, it is recommended to ask a professional repairman.
The above is the basic reason for the excavator to hold up the car. Knowing these factors, the owners or operators need to check more frequently in their daily work to find out the "symptoms" of the excavator in time and "treat" it in time, so as not to delay the normal work of the excavator, improve work efficiency and earn more money.
