AmericaReference number: Geoprobe7822DTHigh temperatures on the drill righigh temperatureWhy?It may be caused by problems with the cooling system, lubrication system, combustion system or mechanical components. Here are the system inspection steps and solutions:

I.America Geoprobe 7822DT Rig High Temperature high temperature Analysis of common causes：

1、Cooling system problems：

A、Insufficient or spoiled coolant：

B、Heater blockage (dust, willow, etc.)

C、Water pump failure (blade damage, water leakage)

D、The thermostat is stuck (can't turn on the large cycle)

E、The fan belt is loose or broken

2、Problem with the lubrication system：

A、Insufficient or deteriorated oil (poor lubrication causes friction to heat up)

B、Lubrication oil filter clogged

3、A combustion system problem：

A、Oil spraying is not on time (too early or too late)

B、The nozzle does not vaporize properly (burns inadequately)

C、Too much load (running overload)

4、Mechanical failure：

A、Damage to the cylinder cushion (coolant leaching into the combustion chamber)

B、Grease of the piston ring (high-temperature gas leak in the tank)

5、Other reasons：

A、The ambient temperature is too high or the ventilation is poor

B、Temperature sensor or instrument failure (false alarm)

II.America Geoprobe 7822DT Rig High Temperature high temperature inspectmethod With maintenance steps：

1. Preliminary inspection

A、Observing Instrument: Make sure that the high temperature alarm is true (compare the actual water temperature with the meter display).

B、Check the coolant: Whether the liquid level is in the standard range and whether the color is normal (cloudy, oily stains may indicate damage to the cushion).

C、Check the oil: Oil level, oil quality (if whitening occurs, it may be mixed with the coolant).

2. Refrigeration system inspection

A、Heater Cleanup: Clean surface blockages with compressed air or water cannon.

B、Pump Testing: After starting, observe whether the coolant circulation is normal (whether the touch water pipe temperature is even).

C、Thermostat Testing: Remove and put in hot water to check the open temperature (The J112 is usually turned on around 82C).

D、Fan belt: Press the middle section of the belt, the amount of dilation should be within10-15mm (too loose to adjust).

3. A lubrication system inspection：

A、Replacement of oil and filter: Use the original manufacturer specified model (e.g.SAE 15W-40）。

B、Check the oil pipeline: Is the oil pump pressure normal (to be tested with a pressure gauge).

4. Burn and load inspection：

A、Oil spraying system：

Check the nozzle vaporization (take off and test the shape of the spray).

Calibrate the correct timing of oil spraying (requires specialized equipment).

B、Load testing: Avoid long periods of overload (rated power)Below 80 per cent is desirable).

5. Mechanical fault diagnosis：

A、Cylinder pressure test: Excessive pressure may indicate a piston ring or cushion problem.

B、Exhaust Color: White smoke may be damaged by the cushion (the coolant enters the combustion chamber).

6.Environment and Instrumentation：

A、Improved ventilation：Make sure there is enough cooling space around the unit (at least)1 m spacing)。

B、Sensor Calibration: Use a Universal Scale to detect whether the water temperature sensor resistance values change with temperature.

III.America Geoprobe 7822DT Rig High Temperature high temperature Examples of Solutions：

case1: The radiator is blocked
phenomenon: High temperature alarm and dust covering the surface of the radiator.
Handle: Clean the radiator thoroughly and restore the temperature after ventilation.

case2: Thermostat failure
phenomenon: The small circulating water pipe is hot, the large circulating water piping is cool.
Handle: Replace the thermostat (note the direction of installation).

case3: Delay in the timing of oil spraying
phenomenon: The exhaust pipe smells of black smoke and the power decreases.
HandleAdjust fuel injection pump timing to normal angle.

IV.America Geoprobe 7822DT Rig High Temperature high temperature protective step How to do this:

1、Replace coolant regularly (recommended)2 years or 2,000 hours).

2、eachClean radiator and replace lubrication oil filter for 500 hours.

3、Avoid long-term low-load operation (which tends to lead to the combustion of room carbon).
