Abstract
The utility model discloses a vertical single stage pump convenient to detach. The pump comprises a pump body, a bracket, a pump shaft and a water-lubricated bearing, wherein a suction port and an exhaust port are formed in two sides of the pump body; the bracket is mounted above the pump body, and a motor is fixed on the bracket; the pump shaft is arranged in inner cavities of the pump body and the bracket, one end of the pump shaft is connected with the motor through a coupler, and the other end of the pump shaft is connected with an impeller which is arranged in the inner cavity; the water-lubricated bearing is connected with a lower end cover below the pump body. A mechanical seal gland is circularly arranged on the outside of the pump shaft at the joint of the pump body and the bracket. A mechanical seal is arranged at the joint of the mechanical seal gland and the pump shaft. According to the vertical single stage pump convenient to detach, by the aid of the arrangement manner, axial force is reduced, and a mechanical seal is located in a low pressure area, so that service lives of the mechanical seal and the bearing are prolonged. At the same time, the mechanical seal and the impeller are convenient and rapid to replace, and user requirements can be well met.
Description
Technical field
The utility model relates to single-stage pump field, particularly a kind of vertical single stage pump of just tearing open.
Background technique
For reply single-stage pump market is to life-span and the requirement of just tearing open, single-stage pump is in the market widely used, its impeller inlet, causes axial force large down, and shaft strength is larger, cause bearing life to reduce, meanwhile, machine sealing position is in zone of high pressure, and machine envelope is stressed larger, its wearing and tearing are also larger, thereby its life-span also reduces.For single-stage pump, machine envelope belongs to easily damaged parts, is easy to break down, and when changing, when common single-stage pump is more changed planes envelope, need to dismantle motor and pump cover, could change it.Waste time and energy very much, can not accomplish convenient, fastly, also affect working time of pump.
Model utility content
The purpose of this utility model is to provide a kind of and improves bearing and machine envelope life-span, be convenient to more to change planes envelope and impeller just tear vertical single stage pump open.
In order to solve the problems of the technologies described above, the utility model is just torn vertical single stage pump open, comprising: the pump housing, is provided with suction port and exhaust port in the both sides of the described pump housing; Support, described support is arranged on the top of the described pump housing, on described support, is fixed with motor; Pump shaft, described pump shaft is arranged in the inner chamber of the described pump housing and described support, and one end of described pump shaft is connected with described motor by coupling, and other one end of described pump shaft is connected with impeller; Wherein said impeller is arranged in the inner chamber of the described pump housing, and described impeller inlet upward; Water lubriucated bearing, described water lubriucated bearing is connected with the lower end cap of described pump housing below.
Described pump shaft outer ring in the described pump housing and described support joint is provided with machine sealed cover.Connecting part at described machine sealed cover and described pump shaft is provided with mechanical seal.
The utility model is just torn the arrangement of vertical single stage pump impeller open, and axial force is reduced, and allows machine sealing position in low pressure area, thereby reaches the life-span of increase machine envelope and bearing.Allow in the envelope and convenient, fast during impeller of more changing planes simultaneously, can better meet consumers' demand.
Accompanying drawing explanation
Fig. 1 is that the utility model is just torn vertical single stage pump open and partly cutd open figure.
The utility model is just torn description of reference numerals in vertical single stage pump accompanying drawing open:
The 1-lower end cap 2-exhaust port 3-pump housing
4-mechanical seal 5-machine sealed cover 6-support
7-motor 8-coupling 9-pump shaft
10-impeller 11-suction port 12-water lubriucated bearing
Embodiment
Below in conjunction with accompanying drawing, the utility model just being torn open to vertical single stage pump is described in detail.
As shown in Figure 1, the utility model is just torn vertical single stage pump open motor 7, support 6, the pump housing 3, Pump Suction Nozzle 11 and pump discharge 2, impeller 10, pump shaft 9, mechanical seal 4, machine sealed cover 5, lower end cap 1 and coupling 8 is housed.Motor 7 is fixed on support 6, and support 6 is connected with the pump housing 3, and the both sides of the pump housing 3 are provided with Pump Suction Nozzle 11 and pump discharge 2.Pump shaft 9 is connected by coupling 8 with motor 7, impeller 10 is contained on pump shaft 9, and machine sealed cover 5 is provided with mechanical seal 4 with the binding site of pump shaft 9, and machine sealed cover 5 is fixed on the pump housing 3, the pump housing 3 lower ends are furnished with lower end cap 1, and lower end cap 1 carries out drive fit with water lubriucated bearing 12.In mechanical seal 4, rotating ring is done High Rotation Speed with impeller 10, and in mechanical seal 4, stationary ring is fixed on the pump housing 3.Rotating ring and stationary ring form end face seal by friction pair, reach and stop liquid in pump reveal and prevent that pump outer air from leaking into the object in pump.
During work, starting electrical machinery 7, impeller 10 is High Rotation Speed under motor 7 drives, and the liquid work done of carrying from Pump Suction Nozzle 11 is produced to lift (pressure), through pump discharge 2, discharges.Complete the overall process that the mechanical energy of prime mover (being generally motor) is changed into the energy (kinetic energy, pressure energy, potential energy) of liquid, realize liquid by low pressure to high pressure simultaneously; Object by lower position to high position and long distance conveying.Upward, in water pump operation process, mechanical seal 4 is in low pressure area, stressed less in impeller 10 imports, the axial force that simultaneously impeller 10 produces upwards, concerning whole pump, can the downward axial force of balance, thereby shaft strength is reduced, arrive the object that increases bearing life.When need are changed mechanical seal 4, the coupling 8 of only need dismantling, then lays down machine sealed cover 5, just can change quickly mechanical seal 4, same, and when changing impeller 10, the lower end cap 1 of only need dismantling, just can change impeller 10.Thereby arrived the object of just tearing open.
Below the preferred embodiment of the utility model having been created illustrates, but the utility model is created and is not limited to described embodiment, those of ordinary skill in the art also can make all modification being equal to or replacement under the prerequisite without prejudice to the utility model creative spirit, and the modification that these are equal to or replacement are all included in the application's claim limited range.
