A few easy tricks to get rid of the ＂dementia＂ of your excavator, efficient construction!

Do you often encounter

The excavator has no power, whether it's rotating or moving.

It's like having Alzheimer's disease

Today we will teach you a few tricks

Easy to solve the problem of slow movement of excavators

Slow movement of components

Single action implementation when the operation is slow, including walking, lifting arm, turning, digging bucket rotation and other operations, this situation can be generally from three aspects to 

find the cause of the failure.

1. Failure of the parts themselves

That is, the action components themselves to receive poor information or implementation of the process of poor contact, or the relevant components of their own relief valve pressure is too low, 

excavators can tap the components to see if there are screws loose or pressure test, so as to carry out maintenance and processing.

2. Conduction process failure

That is, the command conduction process failure, hindering the transmission of command signals, so you can focus on checking the pump, low pressure sensor and multi-way valve situation to see if 

there is a failure.

3. Operation center failure

That is, the excavator's command issued by the center failure, resulting in the signal can not be issued, this situation is generally more complex, but also need professional maintenance guidance, the 

excavator can double-check the relevant solenoid valve failure, whether the spool card.

Slow movement of the whole excavator

1. Hydraulic system

Hydraulic system is one of the excavator's power system, if the excavator is slow, you should check the hydraulic system, whether there is daily on-time maintenance, and whether the hydraulic oil is 

regularly replaced. Expired hydraulic oil will not only affect the effect of the excavator performance, but also corrosion of the hydraulic wall of the excavator. At the same time, you should also check 

the hydraulic oil circuit and oil return filter element whether there is blockage, if there is blockage, then you should clean up the oil circuit, and when serious, you should replace the parts.

2. Engine power is too low

With the same hydraulic system, the engine is also one of the excavator's power system. Low engine power will lead to low output power, and then the excavator holding the car, so that the 

excavator vehicle action is slow.

3. Hydraulic pump

Hydraulic pump output is insufficient, which belongs to one of the hydraulic system conduction faults, excavators can enter the service diagnostic system for the relevant pressure test to see 

whether the hydraulic pump conduction caused by the excavator slow action.

Slow movement of hot engine

1. Check the oil

Check whether the fuel used meets the requirements of the excavator, if the fuel has not been replaced for too long, or the oil is too dirty, you need to replace the fuel. At the same time, if the oil 

inlet filter with copper shavings, will scratch the main pump to form wear, this time to clean up the filter.

2. Filter blockage

Filter blockage will lead to the oil circuit is not smooth, so check to see whether the pilot filter, return filter, suction filter is blocked, if the filter is blocked, you need to clean up the blocked material, 

serious need to replace the filter.

3. Main pump regulator

The main pump conditioner piston stained with mud, excavator daily work most of the time is to deal with dirt, so the piston stained with mud is unavoidable, but the piston blockage will lead to the

 main pump pump pressure reduction, the output power is reduced, so that the excavator moves slowly.

Excavator slow-moving problem, certainly make the boss very unhappy, but no doubt this is also the excavator to everyone a signal, this time, must carefully check the excavator failure. From these aspects of a comprehensive overhaul of the excavator, so that our excavator to get rid of "dementia"!
