Abstract
The utility model relates a new-structure vertical double-suction pump consists of an electric motor, an elastic dowel-pin coupling, a base for the electric motor, a transmission axle, a pump body, a pump axle, an impeller and a pump base. The vertical double-suction pump is characterized in that the transmission axle between the electric motor and the pump body is connected with the rigid coupling; and the electric motor is positioned on the base for the electric motor on a beam top of a supporting frame. Between the pump axle and the pump body is sealed with the packing materials. The upper and lower sides inside the pump body are connected with the pump axle through a sliding bearing component. The inner wall of the pump body is connected with a water-piloted bearing. The water-piloted bearing is tangent to the edge of the impeller. The utility model has the advantages that the vertical double-suction pump can operates under the condition that the pump is totally submersed at the place where the water fall is great, and the structure makes a more reliable operation for the big-type pump.
Description
Technical field
The utility model relates to a kind of vertical double suction pump of vertical double suction pump structure, particularly a kind of new structure.
Background technique
The mounting structure of existing vertical double suction pump as shown in Figure 1 at present, at lowermost end is pump seat, the major part of the rotor part of pump is: axle, impeller, impeller nut, the lower end water pilot bearing of axle leans on the coupling end with two deep groove ball bearings, the supporting way of motor leans on the support between motor and the pump, the mode of the being in transmission connection elastic dowel pin shaft coupling of axle.Above structure has following some deficiency: 1, for the big motor of match power, on the one hand weight is big, and the power that support bears is just very big, the suffered power of motor and pump on the other hand, and moment of torsion, rotary inertia etc. also can be very big, vibration will take place like this and unstable.2, big in this way pump, the weight of rotor part is not little, so the axial force of being born during pump operation is also very big, it is insecure bearing by two that the less deep groove ball bearing of axial force bears, deep groove ball bearing is perishable with regard to rapid wear like this, in case damage of bearings, choma and impeller will bump against and damage so.3, this mounting type inconvenience dismounting, maintenance.4, water pump can not move under the situation that water logging does not have.
Summary of the invention
The purpose of this utility model is the existing the problems referred to above of mounting structure that solve vertical double suction pump in the prior art, and a kind of novel mounting structure of vertical double suction pump is provided.The vertical double suction pump of the utility model design new structure, comprise that motor, elasticity leans on pin coupling, motor cabinet, transmission shaft, the pump housing, pump shaft, impeller, pump seat, it is characterized in that: motor is connected by rigid coupling with transmission shaft between the pump housing, motor is positioned on the motor cabinet on top of supporting frame crossbeam, be sealed into packing seal between the pump shaft and the pump housing, two ends connect pump shaft by plain bearing element up and down in the pump housing.Be connected with water pilot bearing on pump housing inwall, water pilot bearing and impeller edge are tangent.The utility model has the advantages that to make vertical double suction pump can under the complete covered situation of water pump, move, and structure is more reliable for the magna pump operation in the bigger place of the height of water.
Description of drawings
Accompanying drawing 1 is the prior art constructions schematic representation,
Accompanying drawing 2 is a structural representation of the present utility model,
Below in conjunction with drawings and Examples the utility model is elaborated,
Embodiment
Comprise among the figure that motor 1, elasticity leans on pin coupling 2, motor cabinet 3, transmission shaft 4, the pump housing 5, pump shaft 6, impeller 7, pump seat 8, it is characterized in that: motor 1 is connected by rigid coupling 9 with transmission shaft 4 between the pump housing 5, motor 1 is positioned on the motor cabinet 3 on top of supporting frame crossbeam 10, be sealed into packing seal 11 between the pump shaft 6 and the pump housing 5, two ends connect pump shafts 6 by plain bearing element 12 up and down in the pump housing 5.Be connected with water pilot bearing 13 on the pump housing 5 inwalls, water pilot bearing 13 is tangent with impeller 7 edges.Because motor 1 separates with the pump housing 5, and motor 1 is placed on the motor cabinet 3 on top of supporting frame crossbeam 10, therefore satisfy vertical pump and can be placed on the big place use of the height of water, and the pump housing 5 can be fully in water, both do not disturb mutually when maintenance, just can overhaul separately as long as pull down rigid coupling 9.Employing rigid coupling 9 makes elasticity lean on pin coupling 2 parts and pump shaft 6 becomes an integral body, realizes the balance of axial force of transmission shaft 4 and pump shaft 6, and the radial force of water pump is born by two water pilot bearings 13.
Claims (2)
1, the vertical double suction pump of new structure, comprise that motor, elasticity leans on pin coupling, motor cabinet, transmission shaft, the pump housing, pump shaft, impeller, pump seat, it is characterized in that: motor is connected by rigid coupling with transmission shaft between the pump housing, motor is positioned on the motor cabinet on top of supporting frame crossbeam, be sealed into packing seal between the pump shaft and the pump housing, two ends connect pump shaft by plain bearing element up and down in the pump housing.
2, by the vertical double suction pump of the described new structure of claim 1, it is characterized in that: be connected with water pilot bearing on pump housing inwall, water pilot bearing and impeller edge are tangent.
