What preparations do the onboard pump do before pumping the concrete?

Release time:2019-02-16 Author: Click:

For a vehicle construction pump that is relatively unfamiliar, it is not known how to start using it when it is used on the construction site. I don’t know what preparations to use before pumping concrete with a car pump. Let’s talk about it. Some preparations for the on-board pump before pumping the concrete, so that the vehicle pump can be used better when it is under construction.

What preparations do the onboard pump do before pumping the concrete?

Before pumping concrete, the Koneile Group vehicle pump should first pump clean water, check the pipeline blockage to ensure that the seal is impervious to water; then pump the pipeline lubricant, we usually use mortar or cement mortar, the mortar dosage is 0.5 cubic meters. Meter / 200 meters. Cement mortar concrete ratio cement sand, when the pipe length is less than 150 meters, it is a 1:2 ratio. When the pipe length exceeds 150 meters, it is 1:1 ratio. First, we pour the mortar into the hopper of the pumped car pump, and then we can pour out the concrete that meets the normal pumping requirements before the mortar is pumped out. If a blockage occurs while pumping the mortar, the front tube can be removed, the dewatering block can be removed, and the tubing can be properly connected for proper operation. The fluctuation of pumping concrete slump should not be too large, and the range of variation is controlled within (100-230) MM. When pouring the concrete into the on-board pump hopper with a mixer truck, it should be stirred quickly for a few minutes in the mixer drum. Before using the onboard pump, we must do this to avoid problems during the operation of the project. Only when we do well in the details can we better complete the progress of our project.
