Concrete wear-resistant pump pipe installation
In the field construction of concrete wear-resistant pump pipe installation and commissioning is very important, on how to use the concrete wear-resistant pump pipe directly related to the progress and quality of the project, the author set many years of concrete pump design, production technology and field construction experience Make some exhaustive overview of this. When installing concrete pump to test the source of concrete. If it is commercial concrete, mixing and transport vehicles, delivery of wear-resistant pump tube can be installed locally, as long as the convenient take over and feeding can be. If the scene is mixed with concrete, first according to the site and mixing and machine feeding way to determine the mixing and machine position, and then according to mixing and machine discharge height and wear-resistant pump to send and take over the tube to determine the requirements to determine the concrete pump s position. 1. First, place the concrete pump on a solid concrete floor or stone pier to maintain the degree and lock the positioning pins and safety pins on the four legs of the pump to release the tire from the ground or remove the tire. 2. According to mixing and machine discharge port and abrasion pump tube hopper to make a chute, mix and discharge the material through the chute into the pump hopper. 3. The chute is usually made of angle steel, welded with 1.5mm thick steel plate. Under the chute with a support frame, so that the solid. 4 under normal circumstances, the wear-resistant pump tube hopper need to increase about 20cm, so increase the hopper volume to ensure that concrete will not drain. Because the mandatory mix and machine unloading the best finish unloading, so that the concrete flow into the hopper symmetry. If the grading discharge, the last out of the concrete stones too much, on the pump unlucky, especially when the slump of concrete larger, it should be noted that the hopper pump to be raised. If it is a large volume of mixing and machine, you can make a storage hopper in advance to ensure continuous feeding. 5. In the chute placed on the required slope appropriate, the most fortunate tilt angle between 25 ° -40 °, the gap should not be too large. 6. Chute and pump hopper connection, the chute and hopper to leave some space for easy cleaning hopper and sieve. 7. After installation, take an overview of the whole, to ensure the transmission of wear-resistant pump tube casing door switch freely, easy maintenance operation.
