What is the reason why the excavator speed drops?
Recently, one of the hot topics in the field of construction machinery is the issue of excavator speed loss. Many machine owners and operators reported that the excavator's speed suddenly dropped during operation, seriously affecting work efficiency. This article will combine the hot content of the entire network in the past 10 days, analyze the common reasons why the excavator speed drops, and provide structured data to help readers quickly understand.
1. Common causes of excavator speed loss
The speed loss of the excavator is usually related to the following faults:
| Cause classification | Specific performance | possible consequences |
|---|---|---|
| fuel system problems | Clogged fuel filter, fuel pump failure, poor fuel quality | Insufficient oil supply to the engine and reduced power |
| Air intake system problems | Air filter clogged, turbocharger failure | Insufficient combustion and reduced power |
| Hydraulic system problems | Hydraulic pump wear, hydraulic oil contamination, valve block stuck | The hydraulic load is too large and the engine speed drops. |
| electrical system problems | Sensor failure, ECU program error, poor line contact | Abnormal engine control signal |
| Engine mechanical failure | Piston rings are worn, valve seals are not tight, and fuel injection nozzles are clogged. | Engine power is insufficient |
2. How to troubleshoot the problem of excavator speed loss
For the above reasons, you can follow the following steps to troubleshoot:
| Troubleshooting steps | How to operate | Things to note |
|---|---|---|
| Check fuel system | Replace fuel filter and check fuel pump pressure | Make sure to use fuel that meets standards |
| Check air intake system | Clean or replace air filter, check turbocharger | Prevent dust from entering the engine |
| Check hydraulic system | Measure hydraulic pump pressure and replace hydraulic oil | Avoid hydraulic oil contamination |
| Check electrical system | Read the fault code and check the sensors and wiring | Use professional diagnostic equipment |
| Check engine mechanical parts | Measure cylinder pressure and check fuel injectors | It is recommended to be operated by professional technicians |
3. Recently, there has been a hot discussion on the Internet about the speed loss of excavators.
According to search data in the past 10 days, the problem of excavator speed loss has triggered extensive discussions on major construction machinery forums and social media. The following are some hot topics:
