The technological scheme that realizes above-mentioned purpose is: the auxiliary support apparatus on a kind of condensate pump of used in nuclear power station, described condensate pump comprise vertical outer cylinder body and are located in the inner chamber of outer cylinder body and are suspended on the pump housing on the top board of outer cylinder body.Described auxiliary support apparatus comprises a fixed base, a spring pedestal, a spring bracket, a spring and a supporting frame, wherein:
Described fixed base is cylindrical and be fixed on the bottom surface central authorities of described outer cylinder body;
Described spring pedestal comprises that a spring chassis and is connected to the chassis support cylinder of this lower end, spring chassis, the internal diameter of this chassis support cylinder is greater than the external diameter of described fixed base, and this spring pedestal is fixed on the bottom surface of described outer cylinder body to be enclosed within coaxially the outer mode of described fixed base;
Described spring bracket comprises that a dish and is connected to the spring spool of this dish lower end, the internal-and external diameter of described spring spool is adaptive with the internal diameter of the external diameter of described fixed base and described chassis support cylinder respectively, and this spring bracket is enclosed within the mode that described chassis support cylinder bottom outer and described spring spool is clipped between described fixed base and the described chassis support cylinder with described spring spool and is connected on the described fixed base;
Described spring fitting is also spacing by described dish and described spring chassis outside described spring spool;
The upper end of support frame as described above is connected with the lower end of the described pump housing, so that the lower end surface frame of supporting frame is placed on the frame dish of described spring bracket.
Auxiliary support apparatus on the condensate pump of above-mentioned used in nuclear power station, wherein:
The upper-end surface of the frame dish on the described spring bracket is a up big and down small conical surface, and the lower end surface of support frame as described above is the conical surface adaptive with the tapering of the upper-end surface of described dish;
Offer in uniform way two axial waist shaped holes on the wall of the chassis support cylinder on the described spring pedestal, so that described spring bracket is connected with described fixed base by two pins that pass one by one these two waist shaped holes.
The technological scheme of the auxiliary support apparatus on the condensate pump of used in nuclear power station of the present invention is simple in structure, can effectively eliminate the vibration of water pump, reduce noise, reliability is high, can support the pump housing better, that has simultaneously eliminated also that thermal effect causes does not wait swell increment, reduces the thermal strain of coupling in the pump group, guarantees to reach the working life of pump group the requirement in 60 years.
Description of drawings
Fig. 1 is the structural representation of the auxiliary support apparatus on the condensate pump of used in nuclear power station of the present invention.
Embodiment
In order to understand technological scheme of the present invention better, below by embodiment particularly and be described in detail by reference to the accompanying drawings:
See also Fig. 1, the auxiliary support apparatus on the condensate pump of used in nuclear power station of the present invention comprises a fixed base 11, a spring pedestal 12, a spring bracket 13, a spring 14 and a supporting frame 15 again, wherein:
Condensate pump comprises vertical outer cylinder body 2 and is located in the inner chamber of outer cylinder body 2 and is suspended on the pump housing 3 on the top board of outer cylinder body;
Fixed base 11 is cylindrical and be fixed on the bottom surface central authorities of outer cylinder body 2;
It is spacing that spring 14 is installed in the spring spool 132 of spring bracket 13 spring chassis 121 outer and the frame dish 131 by spring bracket 13 and spring pedestal 12;
The lower end surface 151 of supporting frame 15 is the conical surface adaptive with the tapering of the upper-end surface of the frame dish 131 of spring bracket 13, and the upper end of supporting frame 15 is connected with the lower end of the pump housing 3, and the lower end surface frame of supporting frame 15 is placed on the frame dish 131 of spring bracket 13.The centrifugal force that produces when the pump group is moved, the conical surface of supporting frame 15 lower end surfaces 151 and 13 of spring brackets coil 131 and contact with conical surface, limited well radially rocking of the pump housing, and spring 14 can reduce the axial vibration of the pump housing.
