How do you find the center of a vertical circulation pump?

　　Vertical circulating pump how to find the center, vertical pump to improve the quality of the installation of the key is to find the center, the center is not allowed to find, will affect the normal operation of the pump, the center to find the right, you can start a time to work properly, to ensure the subsequent safe and effective operation.

　　1. Vertical circulation pump to find the center of the principle: first find the opening, and then find the circumference, using the percentage of the top of the wire method (pay attention to adjust the percentage of the zero).

　　2. First use the board ruler and motor foot top wire rough to find the circumference of the wheel according to the mark symmetrical wear two screws, in order to disc car at the same time, the end face frame table, table seat suction in the circulating pump on the wheel, the table needle vertically on the top of the motor to the wheel end face, respectively, record the original data of the four positions of the opening, can be calculated to the end of the face of the opening fingers.

　　3. circumference frame table, table seat staggered 90 degrees the same suction in the vertical pump on the wheel, the table needle vertical top in the motor against the wheel outer circumference, disk motor and record the circumference of the four direction table value, in turn, calculate the outer circumference of the displacement deviation, with the motor top wire top motor bottom corner, adjust the circumference of less than 0.05mm.

　　4. After tightening the bottom corner, disk the motor for a week, check to confirm that the circumference and opening are not more than 0.05mm.

　　Vertical single-stage circulating pump to find the center of the standard and adjustment method

　　1, find an electrician to test whether the new motor is qualified to clean up the motor base plate above the debris (silt, dust, rust and dirt, etc.).

　　2, lifting the motor to the seat above the anchor bolts (bring in can be) with a cutter ruler to detect the water pump and motor coupling height.

　　3, after the detection of the pump and the motor of the high and low situation of the pre-adjustment shims and then adjust the center of the situation, so that its coaxiality to achieve a more satisfactory state.

　　4, detection of radial deviation, with a ruler for light transmission detection, according to the detection of the motor height to reduce and increase the adjustment shims detection of axial deviation, with a plug ruler to detect the upper and lower opening conditions, to eliminate the coupling end face opening, on the opening of the back foot shims (or reduce the front foot shims), under the opening of the opposite, up and down the opening after the completion of the adjustment, with the help of the top wire to adjust the left and right openings (Note: the motor plus adjusting the piece of excessive, should be appropriate to replace the thicker single piece of shims, and then adjusted to achieve a better coaxiality. Should be appropriate to replace the thicker single piece of gasket, to prevent tightening the error is too large).

　　5, after the completion of coarse correction, fasten the foot, the percentage of the table frame installed in the equipment coupling, the percentage of the table bracket installation requirements are firm and reliable without collision, the percentage of the table rod installation requirements to leave the amount of expansion and contraction, the table pointer adjusted to the zero position to turn the table to detect the record 0 °, 90 °, 180 °, 270 ° table turn zero integer value.

　　6, axial data based on the correction formula (motor foot from the end of the shaft size multiplied by the number of tables than the diameter of the back wheel to adjust the thickness of the pad) for careful adjustment of the gasket size, to reach (0 ~ 0.1) mm within the scope of the elimination of up and down the mouth.

　　7, radial table is measured by the overall height of the motor, the number of tables on the table minus the number of tables divided by 2 is the motor needs to be adjusted as a whole height (positive values to reduce the motor foot pad thickness, negative values plus pad). After adjusting the left and right circumferential, radial to reach the standard (between the two backrest wheels required to leave 3 ~ 5mm tampering), and finally tighten the foot, playing the meter to reach a qualified number.

　　8, a separate test run motor steering, after confirming that there is no problem, install the coupling pin and tighten.
