Pour the grout from a head box that is positioned at an elevation higher than the baseplate to provide a static head for the grout to flow. Some common goals clients report to me include having a pump that operates reliably for a long time combined with an inexpensive installation. The plate is commonly 1 by (2 or 3) ft [300 by (600 or 900) mm] with the grout flowing in the long direction. Detailed and timely information enables performance to reach new levels. Place some tension on the anchor bolts relative to the base when grouting to keep the base from floating. The equipment (pump and driver) should be removed from the baseplate during the grouting process. Let’s go back a minute…the driver is aligned to the driven component, Pump, Compressor, Fan, etc. This article does not address stilted pump bases. A conventionally grouted base plate usually requires two pours, plus additional time and manhours spent for repair-filling of any voids once the grout has cured. If required, the base frame bottom should be painted with epoxy grout primer. Consider these questions: When was the last time you turned the baseplate over and prepared the surface to be grouted? Curing time for grout, especially epoxy grout, depends on the ambient temperature. Grout can also be pumped from the centre of the bearing plate where it spreads to the outside equally on all sides. a Process Industries Practices (PIP) type baseplate. Do not use oil because it can react with the grout substrate. They will have prepared the surface solely to prevent corrosion in the transit and storage stages. The plate is held down by bolts an- chored in the concrete. Anyone with pumps that operate in this manner for more than three years with no downtime for bearings, mechanical seals or couplings also has luck on their side. 2. Alternatively, for large grouting areas, a grout lance is placed through the gap to the other side and withdrawn slowly as pumping proceeds. I would argue that it is rare to accomplish both on the same job. Elsey may be reached at jim@summitpump.com. pour hole to the point farthest away. Base Grouting Process ... for the base grouting process. Utilizing a pregrouted baseplate with conventional grouting methods helps to minimize some of the cost, but the last pour still requires a full grout crew, skilled carpentry work, and good logistics. Without the plate to provide initial grout distribution across the entire shaft base, staged grouting of ... measurements of grout pressure at the pump, and strain gages at the shaft base (1 in = 25 mm, and 1 kip = 4.4 kN). To start, do not assume the mechanical contractor may be the best at the pump installation process. be spillage. On exterior base plates the grout keeps water from sitting in the plate/pier joint. If the site is too hot or cold, steps must be taken to change or control the situation, such as temporary insulated shelters or shade from the sun and heat. Continue this process until all air is vented and all voids filled. I have added (drilled) plenty of vent holes in the base to allow for the venting process. Installation Procedures - Epoxy Grout 03 63 00 epoxy GroutinG 3-433 Construction expansion Joints 1. Their structural integrity is also better since no grout holes are necessary. This is a highly recommended step. Pump baseplate installation and grouting techniques covered are applicable to any turbomachinery baseplate, bed rail, or skid installation. By sloping out from the base plate you can get a little more bearing area on your pier. To read other articles in the 'Common Pumping Mistakes' column, go here. They also informed us that they do not back off leveling nuts below the base plates during the grouting process. 6. It was easy if the base manufacturer designed for the use of jack screws, but even when that was not the case, they were easy to adapt and install in the field.
