The following is the reason for rotary motor, engine rotary, high temperature, slow rotary speed and inspection maintenance and repair methods, excavator walking rotary motor maintenance find Song, professional treatment of this fault for many years. Repair excavator repair factory of excavator industry, repair excavator smoke, high water temperature, difficult to start, slow action, suffocating car fault, professional technical team, repair various brands of excavator difficult fault. Excavator repair excavator maintenance action is slow, heat engine weakness, high temperature, holding car, action is not coordinated, hydraulic pump, valve computer testing, excavator repair engine oil, lower exhaust, overhaul and other fault maintenance. Excavator maintenance motor series failures, the reasons and inspection methods

With many years of excavator walking rotary motor fault maintenance experience, this paper specifically describes the excavator rotary motor does not rotate, excavator rotary motor high temperature, excavator rotary motor rotation speed is slow and other fault causes and inspection methods.

Reason why rotary motor and engine do not rotate in paper rotary machine abstract:

1, excavator circuit and oil circuit problems (Emerson) cause (cause) does not rotate.

2. Maybe the rotary lock of the excavator is locked.

3. The computer version of the excavator is broken, or the insurance is burned out, which leads to the computer version not rotating because there is no electricity.

4, there is also the excavator rotating solenoid valve (magnet valve) no electricity, or burn can also lead to the excavator does not rotate the fault phenomenon.

Next, Lisong tells the fault inspection, maintenance and repair method of excavator rotating motor rotating speed is slow:

First check and confirm whether the excavator is slow in two-way rotation or slow in one-way rotation? The one-way rotation speed is slow, so check whether the secondary pressure of the excavator pilot is the same or not? If the left and right are different, then further check whether there is screen blocking or oil leakage in the pilot distribution pipe of the excavator? There is no blockage and no oil leakage, so the cause of the failure is the failure of the pilot valve of the excavator. There is blockage, or oil leakage, so it is necessary to clean the inside of the pilot pipe of the excavator or repair it.

Share the reasons leading to high temperature of excavator rotary motor:

Maybe the brake pads of the excavator can’t be released.

1. The reason for the high temperature of the rotary motor of the excavator may be that the excavator gear oil is added too much, or the gear oil is not right.

2. The gear clearance of the excavator is not correct, which is too large or too small, leading to high temperature of the excavator rotating motor.

3, or the rotary motor of the excavator has wear (a basic type of parts failure).

4. It is also possible that the beads in the tray of the excavator are broken

5. If the excavator was repaired before, it is possible that the assembly of the excavator did not pay attention to details and the assembly made a mistake.

It is estimated that the failure to walk is due to insufficient engine power or transmission failure or damage.

So what are the other reasons why the excavator can’t walk? Tashimatsu

1. The upper and lower transmission boxes of the excavator are faulty, leading to the inability to walk.

2, excavator Clutch slipping may also lead to.

3, excavator drive shaft or universal joint broken.

4, excavator brake cylinder (compressed air) and brake Spring (Spring) can not return and brake hub locked.

5, before and after the excavator car and the main drive ablative or damage ring.

To share the fault inspection method of excavator can not walk:

1. First, replace the excavator transmission.

2. Then adjust the engine power of the excavator.

3, and then replace the excavator car and main drive.

4. Finally, replace the excavator transmission box.

The general reason why the excavator can not walk is the above mentioned, the fault can be checked and repaired according to the above inspection method. If there is any problem, welcome to call Lisong for free to tell the solution to the fault, the excavator walking deviant maintenance, walking machine, walking inability and other walking faults. Maintenance excavator proficient in more than ten kinds of imported excavator maintenance knowledge, including technical parameters, maintenance data, structural characteristics, hydraulic schematic diagram, electrical schematic diagram and fault diagnosis methods
