What reason is putty spray machine cannot start?

The power system of putty spraying machine is generally gasoline engine, diesel engine, or 220V motor, or 380V three-phase motor.

Find out what type of power system your machine is, and then find out why it doesn't work.

1. Gasoline engine

We are about to learn about the performance of gasoline generators.It could be the oil supply system, it could be the starter.

First check the carburetor, is not smooth, you can use compressed air clear.Second, check the gasoline is not pure, or there is water or other impurities in the tank, if there is a problem, clean the tank, or replace the genuine no. 93 gasoline.

Check if oil leaks into the combustion chamber, which may also cause the gasoline engine to fail to start.

Finally look at the piston or cylinder is clean, if serious carbon accumulation, will be poor compression, to be thoroughly removed and cleaned.

In addition, if it is the disk turn, unable to start, suggest a new, not expensive, if not changed, then remove the disk, turn the flywheel, because it may also be in use, because the engine lack of oil, resulting in connecting rod and crankshaft bite to death, this is very troublesome, need to find professional personnel for maintenance.

Diesel engines

The prerequisite for the normal operation of a diesel engine is that the well-atomized diesel can be injected into the combustion chamber accurately and timely, and the compressed air in the combustion chamber must reach enough temperature to catch fire and explode.To satisfy these two conditions, it is necessary to start the diesel engine with a high enough speed and a certain temperature in the cylinder.When the diesel engine cannot start, the reasons should be found from the aspects of starting work, fuel supply system and compression.

The reasons are as follows:

First, the ambient temperature is lower. Diesel engines need a higher temperature than gasoline, so you have to raise the ambient temperature to start the engine.

Second, the start speed is low, for the pull rope or hand diesel engine, should gradually increase the speed

Then we will look for solutions from the perspective of fuel supply system:

First, whether there is any oil in the tank, or whether you forget to turn on the tank switch.

Second, there is too much air or water in the fuel supply system. The phenomenon is that the starting speed is not low but does not catch fire, and the exhaust pipe emits white smoke.Inspection method is the diesel filter on the gas release screw or high pressure pump on the high pressure tubing unscrewed, if there is air, that is, there is air.The method of elimination is to tighten the oil connection, and then the high-pressure pump on the release screw unscrew, turn the crankshaft, remove air.Water found in diesel can also be eliminated by the same method.If there is too much water in the diesel, replace it.

Third line or filter blocked.The treatment method is to use the air cylinder to blow out the pipeline, clean the filter, and check whether the oil tank filling mouth filter is intact.

The fourth fuel pump plunger wear, this time should be replaced plunger.

3.220v motor or 380V motor

Check whether the motor is burnt out or the voltage is too low. As for the 380V three-phase motor, please pay attention to whether the motor is reversed or not. It is necessary to replace the position of two fire wires so that the machine can be started.

To sum up, putty spraying machine can not start, to specific reasons specific analysis, according to the actual situation, troubleshooting, to solve.
