Steps and methods for fault diagnosis of excavator

How to diagnose the cause of the fault and deal with it early is a very important task.

Equipment fault diagnosis technology: It can understand and master the equipment running condition during the operation of the equipment or without disassembling the parts, identify the fault location and cause and predict the future technical status of the Komatsu excavator parts.

State monitoring technology: It is an important preventive tool. The application monitoring technology can accurately and timely obtain some information about the technical status of the equipment. Komatsu spare parts

(1), troubleshooting steps

a, familiar with equipment performance and related information

b, on-site observation

c. Find the repair technical file

d, inductive analysis

e, organization and implementation

f, sum up experience

g, troubleshooting methods into the file

(2), fault diagnosis method

A subjective diagnosis method (simple diagnostic technique)

1, look. Look at the speed; see the pressure; three look at the oil; four to see the leak; five to see the vibration; six to see the product (smoothness, ripple)

2, listen. Listen to the noise; listen to the impact sound; three listen to the leak; four listen to the sound

3, touch. One touches the temperature rise; two touches the vibration; three touches the crawl; four touches the tightness

4, smell. (oil smells bad)

5, read. (check file records, failure analysis, check, handover, etc.)

6. Ask. Ask if the pump works normally: When is the time to change the oil, the filter cleaning time; three questions about whether the various valves are adjusted before the fault, there are those abnormal phenomena: four questions replaced the seal or hydraulic excavator spare parts how to troubleshoot the faults that occur in the five questions.

B precision diagnostic technology

It is an anomalous phenomenon with doubt on the basis of simple, using various detection methods to quantitatively analyze the fault, and find out the cause. https://jnjmzm.wixsite.com/sdjygcjx
