Abstract
The utility model relates to a novel submerged pump mixed-flow pump which comprises a pump body, a motor, a pump shaft, a guide vane body and impellers, wherein the motor is arranged in the pump body, the motor is connected with the pump shaft, the upper end of the guide vane is located tightly at the lower end of the pump body, a bearing chamber is arranged at the upper end of the guide vane, the pump shaft penetrates through and is connected with the bearing chamber and connected with the impellers in an inner cavity at the lower end of the guide vane, and an upper alarming device and a lower alarming device are arranged at the upper position and the lower position of the outer wall of the bearing chamber. The bearing chamber which is linked with the guide vane is adopted to support the pump shaft, so that stability and safe usage of the pump shaft are achieved, the high-accuracy alarming requirements and effective extension of operation time when leakage of the pump body occurs can be met through the upper alarming device and the lower alarming device on the top portion and the bottom portion of the bearing chamber, and the novel submerged pump mixed-flow pump is compact in structure, small in vibration, long in service life, high in operation efficiency, accurate in alarming, stable in operation, safe and reliable.
Description
Technical field
The utility model designs a kind of mixed flow pump, particularly relates to a kind of Novel submerged axle mixed flow pump.
Background technique
The bearing structure of tradition diving axle mixed flow pump, its bearing chamber is located on the motor lower end cap, and its bearing is long apart from the impeller Center Length, in the water pump operation process, both increased torsion, increased again the scope of beating of axle, produce easily vibration, destroy mechanical seal, thereby affect service life of equipment.
In addition, the upper warning device of diving axle mixed flow pump is located in the motor lower end cap, and lower warning device is located in the stator body cavity; in practical work process, water leaks in the stator body cavity, in the stator body cavity lubricant oil is arranged; the lubricant oil side of floating on the water; water level rises, and lubricant oil touches warning device, and this moment, water did not enter the pump housing; equipment is just shut down; cause inefficiency, the wasting of resources, the equipment frequent start-stop affects working life simultaneously.
Summary of the invention
The purpose of this utility model is to overcome the problem that prior art exists, and has proposed a kind of novel structure, safe and reliable, the accurately Novel submerged axle mixed flow pump structure of reporting to the police.
In order to achieve the above object, the technical solution adopted in the utility model is:
A kind ofNovel submerged axle mixed flow pump, comprise the pump housing, motor, pump shaft, diffuser and impeller, be provided with motor in the pump housing, motor connects pump shaft, the diffuser upper end locking is in pump housing lower end, it is characterized in that described diffuser upper end is provided with bearing chamber, pump shaft cross-under bearing chamber connects the impeller of diffuser lower end inner chamber, and described bearing chamber outer wall upper-lower position is respectively equipped with upper and lower warning device.
Described bearing chamber outer wall top is provided with warning device, and bearing chamber outer wall bottom is provided with lower warning device.
Compared with prior art, the beneficial effect that the utility model reaches is: Novel submerged axle mixed flow pump structure, removed traditional motor lower end cap, the position of bearing chamber is displaced downwardly in the diffuser, the more close impeller center of the bearing of water pump, compact structure, twist and the amount of deflection of pump shaft have been reduced, the vibration of decrease pump shaft, the pump shaft long service life, the submersible pump operational reliability is high; During the inside and outside generation of diffuser water body seepage, in the stator body cavity lubricant oil is arranged, the lubricant oil side of floating on the water; water level rises to enter and touches lower warning device in the pump housing; this device serves as warning, and do not shut down this moment, and water level continues to rise; lubricant oil touches warning device; upper warning device is reported to the police and control apparatus is shut down, and guarantees the safety of pump housing motor, and warning device is convenient for installation and maintenance; report to the police accurately, the effective time prolongs.
The utility model adopts the bearing chamber supporting pump shaft conjuncted with diffuser, realize stable, the safe handling of pump shaft, high-precision warning requirement and the prolongation of effective time when the upper and lower warning device of top, fitted bearing chamber and bottom satisfies pump housing seepage, its compact structure, vibrate little, long service life, high working efficiency, report to the police accurately, stable, safe and reliable.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Among the figure: the pump housing 1, pump shaft 2, motor 3, diffuser 4, impeller 5, bearing chamber 6, upper warning device 7, lower warning device 8.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
It is shown in Figure 1,
A kind ofNovel diving axle mixed flow pump structure, comprise the pump housing 1, motor 3, pump shaft 2, diffuser 4 and impeller 5, be provided with motor 3 in the pump housing 1, motor is socketed on the pump shaft 2, and diffuser 4 is connected on the pump shaft through bearing, and diffuser one end lock onto on the pump housing, the conjuncted bearing chamber 6 that is provided with of diffuser one end, the impeller 5 that bearing chamber is connected at diffuser the other end inner chamber is passed in the pump shaft supporting, and bearing chamber 6 outer wall tops are provided with warning device 7, and bearing chamber 6 outer walls bottom is provided with lower warning device 8.
Diffuser damages when leaking, and water enters in the stator body cavity, in the stator body cavity lubricant oil is arranged; the lubricant oil side of floating on the water, water level continues to rise, and lubricant oil at first enters and touches lower warning device in the pump housing; this warning device serves as warning, and equipment is not shut down, and water level continues to rise; when lubricant oil touches warning device; equipment downtime is reported to the police accurately, and anti-sealing enters the pump housing; damage motor, guaranteed the safety of motor.
