Use fine aggregate concrete pump techniques

Now use the fine aggregate concrete pump more widely today on how to use fine aggregate concrete pump this problem, give us a presentation.
1, before the job needs to be conveyed to the concrete as to understand, should meet the concrete pump can pump requirements.
2, more than five minutes when the pumping stopped, the operator must be concrete end of the hose is discharged, it will easily lead to the end of the hose due to concrete dehydration, resulting in the next job pumping concrete issues to splash around, and this is also the end of the hose is easily damaged.
3, in order to ensure the boom pumping work in the best condition, should be: the one arm lifted to 45 degrees. The fabric is then swing the lever 180 degrees. Then two arms stretched 90 degrees. 3,4,5 section extending arm and was in horizontal position.
If the last boom can be in a horizontal position, it is ideal for pumping. If the position of this section of the boom is horizontal, then the flow will slow down the speed of the concrete, thereby reducing wear and the end of the hose pipes. When the pumping stopped, only the end of the concrete machinery will flow out of the hose.

5. Place the maximum level allowed by the machine inclination angle of 30 degrees, because the horizontal tilt angle over the General Assembly to make the fabric steering gear overload, and endangering the stability of the entire machine. If the boom in the mobile, one leg or several legs which had been off, this time the operator will have to re-set legs, and keep all of the legs can always supported on the ground.
6, after use, if necessary folding boom extend or retract, be sure to remind everyone that the anti-pump 1-2 times before the action, so to avoid when placing pipes, inside the concrete falling or splashing.
