1. According to the removal process of self suction pump in the opposite order, the self suction pump parts.
2. The stuffing box is arranged on the pump cover, and at the same time, the middle block (wedge block) is filled into the stuffing box and the packing shaft sleeve, so that the pump shaft is right.
3. Followed by the installation of self suction pump coupling, shaft end adjustment nut, motor bracket, etc..
4. Will be assembled motor (in addition to the cold oil is not installed, waiting for the coupling center to find a good re installation, in order to facilitate the adjustment of the center).
5. Since the suction pump motor installed, first with two dial indicator check end of the motor shaft coupling and the plane circle of sway degree should be within the scope of the standard, if does not accord with a standard, should according to the actual situation of thrust of the assembly head clearance or thrust correction head.
6. Check the motor end shaft coupling plane and the circumference of the degree of conformity, the motor shaft and the pump shaft to find the center of the work. Will coupling of motor and pump coupling of the removal mark of positive and two couplings in circumferential direction divided into eight equal parts, in the liquid pump coupling and the plane circle are respectively provided with a dial indicator, barring device by equally slow moving rotor disk read swaying of the rotor value and prepare record; if does not conform to the standard in the round between addition and subtraction gasket or small-scale mobile motor bracket to adjust, until the qualified so far
7. After adjusting the qualified with positioning pin positioning, and by adjusting the shaft end adjustment nut to adjust the clearance between the impeller and the impeller chamber to the qualified range. The shaft ends are adjusted to adjust the nut, so that the gap between the shaft end adjusting nut and the motor coupling is 4mm. The motor shaft coupling, the shaft end adjusting nut and the pump shaft coupling are connected and fixed by a bolt.
8. To block out from the stuffing box, packing, packing gland installation.
9. Clean up the oil chamber of the oil cooler, cooling water pipe joints, motor cover, lubrication pipes and the measurement point, etc..
