How To Deal with The Difficulty in Starting The Engine of A Small Rotary Drilling Rig

The engine of a small rotary drilling rig is difficult to start, which not only delays the project progress but may also pose safety hazards. When encountering such problems, you can start to investigate and handle them from the following six aspects to quickly solve the startup difficulties.

1. Check the fuel system: Verify if the fuel in the fuel tank is sufficient, if the fuel filter is clogged, and if the fuel pipes are damaged or leaking. Ensure the fuel line is unobstructed to avoid difficulties in starting due to insufficient fuel supply.

2. Check the battery power: Use a multimeter to measure the battery voltage. If the voltage is too low, it needs to be charged or replaced in time. Check whether the battery terminals are loose or oxidized to ensure a good circuit connection.

3. Inspect the intake system: Check if the air filter is dirty or clogged, and if the intake pipes are damaged or bent to ensure smooth air intake and prevent insufficient air intake from affecting engine combustion.

4. Check the condition of the spark plug: Remove the spark plug and observe whether the electrode gap is normal, and whether there is any carbon deposit or damage. If necessary, clean, adjust the gap or replace the spark plug with a new one.

5. Check the starting motor: When starting, listen to the sound of the starting motor running. If it is weak or does not rotate at all, check whether the motor circuit connections are loose and whether the carbon brushes are severely worn. Repair or replace the faulty parts in time.

6. Check the preheating device: For situations where it is difficult to start in a low-temperature environment, check whether the preheating plug, preheating controller and other preheating devices are working properly to ensure that the preheating function effectively improves the success rate of starting. 

Conclusion: When the engine of a small rotary drilling rig has difficulty starting, by systematically inspecting key systems and components such as fuel, circuits, and air intake, the problem can be accurately located, and targeted measures can be taken to solve it, enabling the equipment to quickly return to normal operation and ensuring the smooth progress of the project.
