1, If the concrete pump truck is powered by electric motor or diesel engine,the operation shall comply with the relevant part of”electric motor safety operation rules” or “diesel engine safety operation rules”.
2, The pipeline should be support firmly, the joint should be connected firmly, pressure in the line or hanging heavy objects is not allowed.
3, Check whether the electric equipment is in good condition, various kinds of instrument is normal, driving safety device, hopper sieve and safety protection device re complete and reliable. Each part operating switch, button, handle shall be in the right position.
4, Check whether the connection parts is loose, the looseness of drive chain should be kept within prescribed scope.
5, Open the discharge valve, open the motor idling for 2-3 minutes, check whether the parts is normal, direction of rotation is correct.
6, In the process of pumping, watch pressure gauge instructions, if it exceeding the specified pressure, should immediately identify the cause of troubleshooting.
7, Pay attention to check the wear of valves, the seat or extruded tube, if discover leak slurry, should stop to check and repair or replacement, after that operation, then continue to work, if found blocking phenomenon, should be timely check and processing.
