Accompanying drawing explanation
Fig. 1 is desulfuration absorbing tower circulating pump structure chart of the present utility model.
Detailed description of the invention
Below this utility model desulfuration absorbing tower circulating pump is further illustrated.
High-efficiency desulfurization absorption tower circulating pump, is shown in Fig. 1, including the pump housing 1, rear pump cover 2, impeller 3, main shaft 4, back shroud 5, impeller
Automatic compensator for clearance, fluid reservoir 13.
The pump housing 1 sidewall is provided with inlet 11, top is provided with liquid outlet 12, and rear pump cover 2 is located at inlet 11 opposing sidewalls
On；Impeller 3 is located in the pump housing 1；Main shaft 4 is passed rear pump cover 2 and back shroud 5 and is connected with impeller 3 by key 6, key 6 and impeller 3
Connected by impeller holding screw 16.
Impeller clearance autocompensation installation includes elastomeric element 7 and wearing plate 8, and is located between the pump housing 1 and impeller 3, bullet
Property parts 7 one end is fixed on the pump housing 1 medial wall, and the other end is connected with wearing plate 8, and wearing plate 8 is abutted against with impeller 3 phase.The pump housing 1
And be provided with impeller clearance between impeller 3 and automatically compensate equipment, one end of elastomeric element 7 is fixed on the pump housing 1, and other end is fixed
On wearing plate 8, the gap 17 between wearing plate 8 and impeller 3 is compensated automatically by elastomeric element 7, when wearing plate 8 is because of abrasion and corruption
When erosion causes damaging, elastomeric element 7 promote it to move to impeller direction, automatically compensate the gap 17 that abrasion produces, it is ensured that
Gap 17 is fluctuation≤0.5mm in allowed band, and the operating pressure making desulfuration absorbing tower circulating pump is stable, continues to transport in high efficient area
OK.The desulfuration absorbing tower circulating pump simple in construction that this utility model provides, can when wearing plate damages and causes gap unadjustable
Changing wearing plate, maintenance cost is low, it is to avoid scraps problem owing to wearing plate damages the complete machine caused, improves desulfuration absorbing tower
The work efficiency of circulating pump and operational reliability.
