The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.
In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplicity of description, but do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, should not be construed as limiting the present invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.
In addition, the technical features involved in the different embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
The embodiment of the invention discloses a protective device of an axial flow pump of a crystallized salt system, which comprises the following components as shown in figures 1-4: the separator is detachably connected in the inlet end of the axial flow pump 1, the separator is used for enabling fluid with crystallized salt solids to pass through and intercepting massive crystallized salt solids, a guide plate 3 for supporting the separator is arranged at one end, close to the axial flow pump 1, of the separator, and the guide plate 3 is used for guiding the fluid to reduce vibration of the axial flow pump 1.
It should be noted that, because the separator plays a role in separation, the fluid with the crystallized salt solid can conveniently pass through and block the large crystallized salt solid, and the fluid is guided by the guide plate 3, so that the vibration of the axial flow pump 1 can be reduced, and further, a protective device for the axial flow pump of the crystallized salt system is provided, and the service life of the axial flow pump 1 is prolonged.
It should be further noted that when the solid salt block is arranged above the isolation screen 2, the flow of the fluid in the pipeline is affected, the fluid generates turbulence, the pump body is vibrated, and the guide plate 3 is arranged below the isolation screen to reduce the influence caused by the fluid turbulence. The number of the guide plates 3 is more than or equal to 4
As shown in fig. 1-3, the partition is an isolation screen 2. It should be noted that the fluid with the crystallized salt solids enters the axial flow pump 1 from top to bottom, large blocks of salt solids are retained on the isolation screen 2 at the isolation screen 2, and then the solid salt blocks are washed into small blocks by the flushing of the fluid and pass through the isolation screen 2.
As shown in fig. 1 to 3, the number of the separation screens 2 is set to two, and the separation screens 2 are arranged in a semicircular shape. Because the quantity of isolation screen cloth 2 is established to two, conveniently overhauls the change to isolation screen cloth 2.
As shown in fig. 1-3, the isolating screen 2 is provided with a plurality of screen holes 21 for isolating and screening the fluid with crystallized salt solids, and the aperture of each screen hole 21 is less than or equal to 50 mm.
As shown in fig. 1 and 2, an inspection manhole 4 is provided at an inlet end of the axial flow pump 1.
As shown in fig. 1 and 2, the manhole 4 is designed with a boom and is locked by a quick-opening bolt.
As shown in fig. 1 and 2, an observation mirror 5 for conveniently observing the partition is provided at the inlet end of the axial flow pump 1. It should be noted that, the quantity of the solid salt blocks on the isolation screen 2 and the abrasion condition of the isolation screen 2 are observed through a sight glass, and the isolation screen 2 should be replaced in time when the abrasion is serious, so that the impeller is prevented from being damaged when the isolation screen falls into the pump body. When the solid salt blocks on the upper part of the isolation screen 2 are too much through the observation sight glass 5, so that the cavitation phenomenon of the axial flow pump 1 occurs, the pump is stopped in time, and the maintenance is carried out through the maintenance manhole 4.
As shown in fig. 1 and 2, the observation mirror 5 is provided with a washing pipe 6 for conveniently washing salt crystals attached to the inner wall of the observation mirror 5. The inspection time is decided by observing the internal conditions of the sight glass 5 conveniently and directly.
The working principle is as follows: because the separator plays the separation effect, make things convenient for the fluid of taking the crystallization salt solid to pass through and hold back bold crystallization salt solid, carry out the water conservancy diversion through guide plate 3 to the fluid, can reduce axial-flow pump 1's vibrations, and then provide a protection device of crystallization salt system axial-flow pump, prolonged axial-flow pump 1's life.
It should be understood that the above examples are only for clarity of illustration and are not intended to limit the embodiments. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. And obvious variations or modifications therefrom are within the scope of the invention.
