The cleaning work of the vehicle pump pipe is better than that of the ground pump pipe, and the sealing performance of the two is very different. Lubricating agent is superior to lubricating mortar in many aspects. While strengthening the sealing of the ground pump pipe, increase the amount of lubricating agent appropriately, but do not increase or slightly increase the auxiliary water consumption. The pumping pressure will decrease at the beginning, or when Placing a sponge ball at the inlet of the pump to clean the pump tube can solve this problem. Some commercial mixing companies add a small amount of pipe mortar between the pipe lubrication solution and the concrete, which is also a method.
