How to adjust new installed diesel generators

After the installation of the new unit is completed, in line with the requirements of the device, you must open the door to start, the risk will cause dangerous ride, should be taken seriously. In order to prevent the rust of the diesel engine .......

After the installation of the new unit is completed, in line with the requirements of the device, you must open the door to start, the risk will cause dangerous ride, should be taken seriously. In order to prevent corrosion of diesel engines.

The method of removing the oil seal is as follows:

1 The diesel oil heated to 45 ℃ ~ 56 ℃ above, used to remove the external anti-rust oil.

2, the water is heated above 90 ℃, and then poured from the water outlet from time to time, from the side of the cylinder block water switch or pump inlet) out, continuous 2 - 3 hours, and intermittently shake the crankshaft, the piston Top, cylinder liner surface and other parts of the anti-rust oil dissolved out.

3 Clean the oil pan with clean diesel oil and replace it with new oil. Cooling and fuel system, fuel injection speed control system, water pump, start the transmission system should be required to carry out cleaning inspection instructions, and add enough clean cooling water, fully start the battery, do the preparatory work before starting.

Inspection of the unit before the test machine

1 diesel engine test machine before the inspection method is as follows:

1 check the appearance of the unit is clean; feet bolts, flywheel screws and other sports parts nuts loose phenomenon, find the problem in time to tighten.

2 check the parts of the gap is correct, in particular, should be carefully checked into the exhaust valve clearance of several decompression agencies meet the requirements of the gap.

3, the cylinder placed in the decompression position, turn the crankshaft to check the cylinder running sound with or without abnormal sound, crankshaft rotation is free, while the oil pump into a friction surface, and then shut off the pressure reduction mechanism, shake crankshaft, check Whether the cylinder leak, if the crank crank, the feeling is very laborious, that the normal compression.

4 Check the fuel supply system as follows:

① Check the fuel tank cover on the ventilation holes are smooth, if the dirt in the hole should be cleaned. Whether the diesel fuel meets the required grade, whether the fuel is sufficient, and the oil switch is open.

② open the decompression mechanism crank crank crank, each cylinder should have a crisp fuel injection sound, that fuel injection is good. If you hear the fuel injection does not come to the oil, there may be air in the oil, this time you can loosen the diesel filter and fuel pump bleed screw to remove the air in the oil.

③ check the tubing and joints at or against the phenomenon of oil and found a timely solution to solve the problem.

5 Check the water cooling system as follows:

① check the water tank is sufficient water, if the water is insufficient, should be filled with clean soft water.

② check the connection water pipe with or without water leakage phenomenon, find the problem in a timely manner to solve.

③ Check the cooling pump impeller rotation is flexible, the belt is appropriate elastic. Check the belt tightening, rotating the middle of the belt with the hand to push, the belt was pressed 10 ~ 15mm is appropriate.

6 Check the lubrication system as follows:

① check the oil pipe and pipe joints with or without oil leakage phenomenon, find the problem in a timely manner to solve.

② Check the amount of oil in the oil pan, the crankcase next to the amount of dipstick to observe the height of the oil surface is consistent with the requirements of the rules, or should add oil, diesel, winter plus 8 or 11 diesel engine oil, summer plus No. 14 oil. Check if the oil level is found above the height of the rule, you should carefully analyze the reasons for the increase in oil, there are usually three reasons.

When adding oil, add too much.

B. Diesel oil leaks into the crankcase and dilutes the oil.

C. Cooling water leaks into the oil.

③ need to manually fill the oil hole, should be filled with oil to do with grease gun filling grease.

7 Check the starting system as follows:

A. Should first check the starting battery electro-hydraulic proportion is 1.240 ~ 1.280 range, if the proportion of less than 1.180 marked the lack of battery power.

B. Check that the power cord is correct.

C. Check the battery terminal whether the accumulation or oxidation phenomenon, it should be polished clean.

D. Check the starting motor and electromagnetic control mechanism and other electrical contact is good.
