Any equipment needs to be inspected before use, including the self feeding mixer used in construction. However, the inspection is not conducted blindly, but according to some principles. Here are some principles.
One by one, check the feeding diameter run out and end face run out of the mixing drum of the conical reverse discharge mixer, and the meshing between the big gear ring and the pinion of the mixing drum, which shall meet the requirements. If it fails to meet the standards, it shall be handled in time.
Check the sealing part of the mixing drum shaft end of the mixer one by one, and whether the oil supply of the oil supply system is smooth.
Check the clearance between the shovel blade of the mixer and the bottom lining plate or side lining plate one by one.
The water supply error, water supply variation error and water supply time of the water supply system shall be measured one by one and shall meet the requirements.
The self loading mixer shall be subject to idling and 110% rated load test one by one (equivalent weight can be added), which shall meet the requirements.
In short, we should first solve the easy problems, and then solve the more difficult problems. Don't get into trouble at the beginning. First check the exposed, accessible and dismountable parts, and then check the hard to reach and dismountable parts. Check the common fault parts of the mixer, which can quickly determine the fault parts and save time and effort.
"Static" here refers to the static state when it is not started; "Dynamic" refers to the working state after the engine is started. Do not start the car blindly. Before starting the car, do the necessary safety inspection and electrical performance test (to see if there is leakage, ignition or short circuit) to ensure the safety of the mixer.
Power failure is one of the common faults, so when the electrical part fails, the power supply part should be checked first. General then special. Check the general fault first, and then check the special fault. To solve the problems of common and general parts, we must solve the problems of individuality and special circuits. Section inspection of mixer refers to the step-by-step detection and analysis of the suspected fault system in the process of fault diagnosis until the fault point of kneader is found.
When testing the mixer, it should be carried out in strict accordance with its testing principles. If you don't know, you can refer to the above to make the mixer meet the use regulations, so as to ensure the operation efficiency of the mixer and promote the use of the mixer.
