How to use a concrete spraying machine? Only by understanding the performance and structure of the concrete spraying machine in detail can we better use the spraying machine equipment and give full play to its role. In addition, the concrete spraying machine mainly uses compressed air to transport the concrete through the material cavity and continuously transport it along the material pipeline, and then spray it onto the construction surface. The concrete spraying machine is widely used in underground projects, hydropower projects, shafts, tunnels, culverts and other sites for spraying concrete construction. How much does a concrete spraying machine cost?

What is the correct operation method of the concrete spraying machine? How to use the concrete spraying machine? What should be paid attention to before use? Henan Weibang will introduce you to the correct method of using the concrete spraying machine in detail. When using it, the operator must read the instruction manual and familiarize himself with the performance and structure of the equipment as soon as possible before he can start working.

1. Preparation work before starting the concrete spraying machine.

a. Check whether the various line contacts of the electronic control system are firm and whether there is leakage. Whether the grounding of the equipment body is reliable.

b. Observe the oil mark and check whether the lubricating oil is sufficient.

c. Check whether the connection and fastening of each part of the concrete spraying machine are correct and reliable.

d. Run the spraying machine for a short time to grasp the rotation situation (pay attention to whether the rotation direction is consistent with the arrow direction, but do not run it idle for a long time).

e. Check the clamping force applied to the rubber sealing plate. First move the nut wrench on the clamping device rod and tighten it initially. Then tighten it 2-3 times until there is no air leakage at the sealing plate.

2. Stop operation and end the spraying machine.

a. After the spraying is completed, the spraying machine and its accessories should be cleaned in time to prevent the bonded material blocks from clogging the pipeline.

b. The removal of the spraying pipeline should be carried out only after the residual air volume in the pipeline has been completely released. The removed pipeline should be carefully cleaned and checked and placed neatly in a place where it does not affect other work.

c. Clean and collect the rebound material that falls on the bottom plate of the tunnel, add cement according to the proportion specified in the regulations, mix evenly, and use it to pour the ditch.

d. Clean up the rebound materials scattered on the cables, pipes and equipment switches, reconnect the air duct removed from the side of the lane, and carry out civilized construction.

e. Remove the discharge elbow and remove the adhesive on the rubber lining plate and the rotating body.

f. Remove the seat body, remove the remaining dust accumulated in the seat body, check and clean it, and reinstall it in the reverse order of removal for standby use.
