what does hydraulic grouting pump need to pay attention to

• 2018-09-26

The hydraulic grouting pump delivery pipe should have strong support to minimize the state of the elbow and the joint should be firmly connected. Heavy pressure cannot be applied or suspended on the pipeline. Empty operation should be performed to check if the direction of rotation is correct, and whether the transmission part, working device and hopper filter are complete and reliable. Before using cement injection pumps, we need to pay attention to the following issues: The grout pump is used to pump concentrated lime water or lime paste into the pipeline to ensure proper operation of the machine. The mortar can only be placed in the pump when it is working properly. The mortar pump must run continuously. When the mortar is not used for a short period of time, the slurry return valve can be opened so that the mortar can circulate in the pump body. If the downtime is long, pump it every 3 to 5 minutes to allow the mortar to enter the pipe and pump body. Flow to prevent condensation and blockage.

Precautions for cement grouting machine: Before using the first water test, check and check whether the joint and pump packing are leaking; after the dry pump tests the water, send the grout to the lubricating pipe in the pipeline, especially for the first time. Pipes are more important to avoid pipe blockage. Check that the ball valve is operating properly when testing the water. When in use, start the mortar pump and then place the mortar. Use mortar in the mortar bucket at any time to prevent sedimentation. Pay attention to the gauge pointer. When the pressure exceeds the limit, the power should be turned off and then started after the pressure is reduced to prevent the hose from bursting due to high pressure.
