Before pumping the cement plaster spraying machine, first pump clean water. At the same time, check whether the seal of each pipe clamp is intact to ensure that there is no water seepage, and then pump the pipeline lubricant. After the pipeline is lubricated, the concrete pump can be used give away. If the cement plaster spraying machine is blocked, it is recommended to remove the pipe in front of the blockage, take out the dehydration block inside the pipe, and then connect the delivery pipe to restart pumping.
When starting or stopping pumping, contact the operator at the front hose of the cement plaster spraying machine. Construction personnel shall not stand at the exit of the pipe to prevent accidental injuries caused by concrete spraying. When the cement plaster spraying machine is running, do not reach into the hopper and washing room. It is necessary to fix the conveying pipeline of the cement mortar sprayer, and do not bend the conveying hose to avoid explosion. Have to be able to hold the end of the hose of the cement mortar sprayer and stand at the corner of the building to prevent the hose from shaking or the concrete spraying and causing the operator to fall and injure it.
When the cement plaster spraying machine finishes processing the blocked pipeline and pumps again, the construction personnel shall not approach the hose to avoid the hose swinging and the concrete spraying will hurt people. If the pumping interval between the two cement plaster spraying machine is long and the pumping needs to be suspended, it is recommended to pump once every 15 to 30 minutes, with 1 to 2 strokes for the forward and reverse pumps to prevent the concrete in the conveying pipe from condensing .
