Dosing pump base installation steps and attention points

　  (1) After the scoop surface is basically checked and accepted, some pits should be scooped out on the upper surface of the foundation (excluding the horn) before the dosing metering pump equipment is installed. This work is called scoop surface. The purpose of the scoop is to make the concrete or cement grout poured during the secondary grouting to be closely integrated with the foundation so as to ensure the stability of the machine and the equipment. Spatula Ma face method has two methods and wind shovel method. Spatula Ma surface quality requirements are: every 100cm2 should have 5-6 10-20mm diameter pits.
　　
(2) Putting the Horn Before installing the machine and equipment, the foundation plate must be laid on the foundation. The foundation surface at the place where the horn is placed must be leveled so that the horn can make good contact with the foundation surface.
　　
When placing the horns, standard padding (a set of horns placed on each side of the anchor bolt), Tic-Tac-Toe method, cross pad method, unilateral pad method, and auxiliary pad method Plus a set of auxiliary between the horn) and so on. Horn area, number of groups and place the method should be based on the quality of the machine and equipment and the size of the base area to determine.
　　
â‘  Each anchor bolt should have at least one set of horn. The distance between two adjacent sets of horns should generally be kept within 500mm. The horn set should be as close as possible to the anchor bolts when it can stabilize and does not affect grouting.
　　
â‘¡ each group of horn, the horn should be placed under the thin horn on top, the thinnest horn should be caught in the middle, so as to avoid warping deformation; the same set of horn, the geometric dimensions to Same, at the same time on the top of the tilting horn, flat horn below the horn should be flat.
　　
â‘¢ do not bear the main load of the horn group using a pair of oblique horn (that is, the same inclination of the opposite oblique horn along the ramp fit together use), after leveling flat with electric welding.
　　
â‘£ To withstand the main load and equipment in the operation of a strong continuous vibration horn group should not be used instead of flat horn and flat horn.
　　
⑤ each set of horns should be neat and tidy, to ensure good contact, the equipment leveling, each group of horns should be compressed, can be 0.25kg hammer hand-by-group tap, listen to the sound?
　　
â‘¥ equipment leveling, the horn should be exposed equipment, the outer edge of the base surface, the flat horn should be exposed 25-30mm; oblique horn should be exposed 25-30mm; flat horn extension device base surface length should be more than the anchor bolt center .
　　
⑦ adjust the horn, the thread part and adjust the block sliding surface should be coated with grease, leveling, the adjustment block should be left to continue to increase the margin.
　　
(3) Install the base When installing the base, first dosing dosing pump base hanging on the horn, and then find and leveling.
　　
â‘  seat alignment. When the machine is looking up, the vertical and horizontal center lines may be marked on the basis or the vertical and horizontal center line steel wires are pulled on the basis of the steel wire frame, and then the center line of the machine base is found based on this line, The center line coincides with the center line of the foundation.
　　
â‘¡ seat leveling. Stand level, the general use of three leveling installation method. First, place a horn with a high degree of height on one end of the cantilever centrifugal sewage pump base, and also place the required height horn on either side of the anchor bolts 1 and 2 on the other end of the base. Then use the leveling instrument to level the upper surface of the base. When the base is horizontal in both the horizontal and vertical directions, tighten the anchor bolts 1 and 2. Finally, add horns on both sides of the anchor bolts 3 and 4, and also leveling, leveling and then tighten the anchor bolts 3 and 4, the base is installed.
　　
In dosing metering pump base surface measuring level, the level should be placed on the machined surface of the base, in the two directions perpendicular to each other with the spirit level measurement, the level of the positive and negative measurements to be taken twice The average of two readings is taken as the true horizontal reading.
