Sep 09, 2018 · NFPA 20 requires that the fire pump base plate be securely attached to a solid foundation in such a way that pump and driver shaft alignment is ensured. Since most pump room floors slope to a floor drain, a level foundation above the floor is typically the way to accomplish this. NFPA 20-2016 6.4.4 also says 'The foundation shall be
Learn MoreJan 07, 2020 · Starting at the hopper, (where the concrete is added from the mixing truck), the concrete pumper employs a duplex plunger pump to draw in and discharge the product. Here in Alberta, we're used to seeing 3- and 5- cylinder plunger pumps on oilfield equipment, pushing thin cement mixes and proprietary solutions down-hole against high pressures.

Learn MoreJan 28, 2020 · As concrete mixes become more complex in order to address ever-increasing needs for strength and durability and to meet environmental sustainability standards, concrete pumpers often face challenges when it comes to moving concrete …
Learn MoreConcrete being pumped through a line experiences friction with the internal wall of the pipeline. The longer the line, the more friction encountered. For longer pumping distances, the use of smooth-walled steel pipe can lower the resistance. The length of hose used at the end of the pipeline adds to the overall line length as well.
Learn MoreBy far there is lack of research on different working conditions between rigid and flexible dynamics of truck mounted concrete pump booms. First a 3D model has been established by using virtual prototyping technology of a 37 m long boom in Pro/Engineering software. Then the rigid body simulation model has been built. Next modal superimposition method is adopted to change the 4 rigid body booms

Learn MoreA concrete pump is a machine used for transferring liquid concrete by pumping.There are two types of concrete pumps. The first type of concrete pump is attached to a truck or longer units are on semi-trailers. It is known as a boom concrete pump because it uses a remote-controlled articulating robotic arm (called a boom) to place concrete accurately.. Boom pumps are used on most of the larger

Learn MorePumping of concrete is economical if the quantity of concrete required is more than about 1150 m 3 or uninterrupted supply of concrete is needed over a long period as at the beginning of each period of pumping the pipes have to be lubricated by mortar (at the rate of about 0.25 in 3 per 1000 m length of 150 mm diameter pipe) and also at the end of the operation considerable effort is needed

Learn MoreNov 03, 2012 · The concrete base isn't a bad idea to add a little mass to the system. But you're frame is much more likely to contribute vibration than the concrete. I'd either use a very stiff section (i. e. piece of 24 inch pipe) or have your structural guy get off his duff and design you a braced frame that's so stiff, there's no way it can vibrate.
