Abstract
The utility model discloses a main shaft assembly of a plastic magnetic pump. The main shaft assembly comprises a main shaft, an impeller, a first sliding bearing, a second sliding bearing and an inner magnetic rotor. The first sliding bearing and the second sliding bearing are assembled on the main shaft, the impeller is located at one end of the main shaft, the inner magnetic rotor is located on the end, opposite to the impeller, of the main shaft, the second sliding bearing is adjacent to the first sliding bearing, and the first sliding bearing and the second sliding bearing are located between the impeller and the inner magnetic rotor. By means of the structure, the main shaft assembly can avoid radial force borne by an isolating sleeve in use. Therefore, service life of the isolating sleeve is prolonged, maintenance times are reduced, and maintenance cost is reduced.
Description
Technical field
The utility model relates to pump, relates in particular to the main shaft assembly of plastic magnetic force pump.
Background technique
Existing plastic magnetic force pump comprises the pump housing, impeller, pump cover, the first sliding bearing, the second sliding bearing, support, separation sleeve, interior magnet rotor, main shaft, outer magnet rotor and motor, main shaft wherein, impeller, the first sliding bearing, the second sliding bearing and interior magnet rotor are the constituent element of the main shaft assembly of plastic magnetic force pump, main shaft is the Step Shaft with five different-diameters, interior magnet rotor is installed at the maximum diameter place of main shaft, the both sides of interior magnet rotor have respectively the first sliding bearing and the second sliding bearing, the first sliding bearing is supported by pump cover, the second sliding bearing is supported by separation sleeve, separation sleeve bearing radial force during use, because separation sleeve is nonmetallic material, bearing radial force can cause separation sleeve to damage, keep in repair more frequent, maintenance cost is higher.
The model utility content
Technical problem to be solved in the utility model is: a kind of main shaft assembly of plastic magnetic force pump is provided, and the use of the main shaft assembly of this kind plastic magnetic force pump can reduce maintenance frequency, reduces maintenance cost.
Solve this technical problem, the technical solution of the utility model is: a kind of main shaft assembly of plastic magnetic force pump, comprise main shaft, impeller, the first sliding bearing, the second sliding bearing and interior magnet rotor, described the first sliding bearing and the second sliding bearing are loaded on main shaft, described impeller is positioned at an end of main shaft, described interior magnet rotor is positioned at the opposite end of the impeller of main shaft, described the second sliding bearing is adjacent with the first sliding bearing, and described the first sliding bearing, the second sliding bearing are between impeller and interior magnet rotor.
Described main shaft is the Step Shaft with three different-diameters, and the two ends of described main shaft have the thread section of the impeller fastening piece being installed respectively and interior magnet rotor fastening piece being installed.
The main shaft assembly of the utility model plastic magnetic force pump adopts such structure, separation sleeve bearing radial force in the time of avoiding using, thus reduce maintenance frequency the working life of prolongation separation sleeve, reduce maintenance cost.
The accompanying drawing explanation
Below in conjunction with the main shaft assembly of accompanying drawing to the utility model plastic magnetic force pump, be described in more detail;
Fig. 1 is the use status architecture schematic diagram of the main shaft assembly of the utility model plastic magnetic force pump;
In Fig. 1,1, the pump housing; 2, the first sliding bearing; 3, the second sliding bearing; 4, outer magnet rotor; 5, support; 6, motor; 7, separation sleeve; 8, interior magnet rotor; 9, main shaft; 10, pump cover; 11, base; 12, impeller.
Embodiment
As shown in Figure 1, plastic magnetic force pump comprises the pump housing 1, pump cover 10, support 5, the main shaft assembly of plastic magnetic force pump, separation sleeve 7, outer magnet rotor 4, motor 6 and base 11, the main shaft assembly of plastic magnetic force pump comprises main shaft 9, impeller 12, the first sliding bearing 2, the second sliding bearing 3 and interior magnet rotor 8, the first sliding bearing 2 and the second sliding bearing 3 are loaded on main shaft 9, impeller 12 is positioned at an end of main shaft 9, interior magnet rotor 8 is positioned at the opposite end of the impeller of main shaft 9, the second sliding bearing 3 is adjacent with the first sliding bearing 2, the first sliding bearing 2, the second sliding bearing 3 is between impeller 12 and interior magnet rotor 8, interior magnet rotor 8 is positioned at the cavity of pump cover 10 and separation sleeve 7 formation, the second sliding bearing 3 and the first sliding bearing 2 are by pump cover 10 supportings.Main shaft 9 is for having the Step Shaft of three different-diameters, the middle segment length of main shaft 9 is the longest, diameter is maximum, the first sliding bearing 1 and the second sliding bearing 2 are installed in the stage casing of main shaft 9, another two sections of main shaft 9 are assembled respectively impeller and interior magnet rotor, and the two ends of main shaft 9 have the thread section of the impeller fastening piece being installed respectively and interior magnet rotor fastening piece being installed.Such structure, the second sliding bearing that originally was positioned at separation sleeve moves on to the first sliding bearing side at pump cover place, pump cover supporting the first sliding bearing and the second sliding bearing, separation sleeve bearing radial force in the time of avoiding using, extend the working life of separation sleeve, reduce maintenance frequency, reduce maintenance cost.
