Just a few days ago to buy a second-hand excavator 220LC-5 modern excavator but he did not know the detailed parameters of the car, there is provided to slow arm mechanic transfer under the high pressure pump speed is not obvious but hold fast car is very serious. Now is very contradictory, can not work properly, there are understand master, please help, analysis of the reasons below, thank you!
You can go to my "second-hand construction machinery network" on the forum to see, where there are many experts Oh!
There will also be blocked filter hold car a few days ago I went to work a 1700 throttle 800 and just dumped soil live as mentioned arm slowly I suggest you look for the modern staff transfer pump flow should be very simple for them, my family had a 225-7 for three years. I suggest you buy a Liugong 205C quite good
Just lift the arm slowly, if the other action is no problem, then that master is in your car speed problem, only to tune the pumpIf so, you can remove the big arm associated with the safety valve, commonly known as "gun", no need to change before cleaningIf the vehicle is slow if it is the big problem that the master pump was fast speed but the speed is inversely proportional to the load causes you to hold the car if the pump is no problem that the engine not load your pump if the engine is no problem that you lead to serious wear of pump leakage hold car the hydraulic pump is the inside of the cylinder piston disc what are very delicate wear will lead to slow my car(as is the same reason to drive gearbox speed express boring speed is slow. This is why a second start)
The repairman has added a lot of traffic to your machine now, but the pressure is down, so the car is very heavy. Let's adjust it again. To be very appropriate, but you have to try a good car to be hot and cold, hot and tired of homework if he will die.The simpler it is, the harder it is to do it well.
