Excavators, as the more critical mechanical equipment of construction machinery equipment, inevitably have the phenomenon of insufficient driving force in engineering construction work. If you want to improve efficiency reasonably, what should people do?
First, people first discuss the specific manifestations of excavator slowness. Roughly divided into three categories: single slow motion, slow motion of the whole vehicle, and slow motion of the heat engine. People do in-depth analysis on these three problems.
1. Check whether the pressure of the governor valve of the relevant parts of the excavator is too low;
2. Check whether the pump, bottom pressure controller, and multi-way valve have common faults;
3. Whether the relay and valve core have common faults.
So, what should people actually do?
1. First look at whether the entire equipment is maintained on time, whether the gear oil is not blocked or replaced on time; whether the gear oil circuit is blocked, please check the system software pressure during standby, and check whether the oil return filter element is blocked. phenomenon;
2. The power of the diesel engine is too low and the driving force is not enough. Please integrate the DX data to analyze the output status of the diesel engine. Can all the cylinders be working separately; check whether the diesel engine has black smoke from the exhaust pipe, if the fuel injector The damage is more serious, and it will also cause the engine displacement to decrease;
3. The output of the hydraulic oil pump is not enough, and the relevant pressure can be tested when entering the service item detection system;
4. Insufficient leading pressure causes insufficient pressure to open the valve core, resulting in insufficient total flow and slow action;
5. To clear up whether there are problems with the power supply circuit, check the common faults of the excavator CPU, high-voltage and low-voltage controllers, relays and routes;
6. Immediately inspect the oil to check whether the oil is cleaned up. If there are stains, it should be removed first; the product oil is dirty and needs to be removed; check whether there is copper debris on the oil inlet filter, which causes the main valve Damaged, need to be disassembled for inquiry.
