Stationary Concrete Pump Pipe Installation and use
erformance Characteristics and Installation and Application of Concrete Pump Tubes
How to use a good concrete pump tube is directly related to the progress and quality of the project. Therefore, the installation and commissioning of the concrete pump pipe in the construction of the site is very important. The experience of the design, production technology and the accumulated construction of the concrete pump has made some detailed Overview.
1, the first concrete pump placed on a solid concrete floor or stone pier, to maintain the degree of the pump and the four legs of the positioning pin and safety pin locking, so that tires off the ground or remove the tires.
2, according to the mixing and the machine out of the mouth and the concrete pump pipe hopper to do a chute, so that mixing and unloading the material through the chute into the pump hopper.
3, chute is usually used as a skeleton of steel, with 1.5MM thick steel welded together. Chute under the support set up to make it firm.
4, the general environment, the concrete pump pipe hopper on the need to increase about 20CM, so increase the hopper volume to ensure that concrete will not be outflow. Because the forced mixing and unloading machine is best to unload a time, so the flow of concrete into the hopper symmetry. If the sub-discharge, and finally out of the concrete stone on the side, the pumping bad luck, especially when the concrete slump, it should be noted that the pump hopper to be high. If it is a large volume of mixing and machine, you can do a storage hopper in advance to ensure continuous feeding.
5, placed in the chute, the slope required appropriate tilt angle of the most gratitude between 25 ° -40 °, the gap is not too much.
6, chute and pump hopper connection, chute and hopper to leave a certain space, easy to clean the hopper and sieve.
7, after installation in place, look at the whole, to ensure that the delivery of concrete pump tube cover door switch freely, easy maintenance operations.
Performance characteristics of concrete pump
1, the use of triple pump open system, the hydraulic circuit does not interfere with each other, the system operation.
2, with anti-pump function, which will promptly remove the block failure, and a short time to stop waiting for material.
3, the use of advanced S pipe distribution valve, can automatically compensate for wear and tear, sealing performance.
4, the use of wear-resistant alloy glasses and floating cutting ring, long service life.
5, long stroke of the cylinder, extending the life of the cylinder and piston.
6, optimize the design of the hopper, easy to clean, suction performance better.
7, automatic centralized lubrication system to ensure that the operation of the machine to be effective lubrication.
8, with remote remote control, the operation more secure and convenient.
The concrete pump pipe support ground must be horizontal. Otherwise it is necessary to make a horizontal bearing surface. Can not be supported on holes. The pump must be supported on a solid floor. If the maximum pressure of the leg is greater than the allowable pressure on the ground, the support surface or the auxiliary wood must be used to increase the support surface area. Support the concrete pump pipe surface should be flat, solid; machine to be placed horizontally, the work should not be inclined. The legs should be able to support the machine stably and reliably lock or secure. The position of the pump is to facilitate the access of the concrete mixing truck to and from the hopper, but also to facilitate the pumping of the pipe and reduce the pumping pressure loss, while requiring distance from the pouring site, power supply, water supply convenience. Humid Hollow Cylinder: Before pouring concrete, it is necessary to wet the water-absorbent hollow tube and reduce the effect of continuous suction of the hollow cylinder on the quality of the structural concrete. Pouring and vibrating: strict control of the floor, under the steel protective layer and its elevation, attention and strengthen the concrete pouring and vibrating, to prevent the concrete floor of the concrete, Ma face phenomenon. Bamboo sheet: Concrete pump tube bracket must be placed on the bamboo plate, the use of operators should be in the bamboo sheet on the operation, prohibit directly to step on the CBM internal model, so as to avoid unnecessary trouble.
