Abstract
The utility model discloses a circulating pump capable of being conveniently overhauled. The circulating pump capable of being conveniently overhauled comprises a bearing box, a mechanical seal device, a pump shaft, a pump body, a hollow installation seat which is fixedly connected with the pump body and an impeller. The pump shaft is arranged on the bearing box through a bearing, the impeller is fixedly arranged at one end of the pump shaft, the impeller is located in the pump body, and the pump body is connected with the bearing box. The circulating pump capable of being conveniently overhauled is characterized in that an installation plate is fixedly arranged at the back end of the pump body, the back end face of a sealing socket which is arranged in the mechanical seal device is fixedly connected with the installation plate, and the mechanical seal device is located in the installation seat. Due to the adoption of the circulating pump capable of being conveniently overhauled, the prior mechanical seal device which is fixed on the end portion of the installation seat is changed to be fixed in the installation seat, so only the impeller is needed to be taken when circulating pump capable of being conveniently overhauled is overhauled, and the mechanical seal device can be taken from the pump shaft and be overhauled. The circulating pump capable of being conveniently overhauled greatly saves overhaul time and reduces overhaul difficulty.
Description
Technical field
The utility model relates to a kind of recycle pump, particularly a kind of formula recycle pump that just overhauls.
Background technique
Recycle pump is the circulating liquid pump of carrying reaction, absorption, separation, regeneration of absorption solution in the finger device, and working principle is water circulation to be got up usedly, and it has wide range of applications, especially the key equipment in the external heating type vacuum salt production system.Existing circulation pump structure as shown in Figure 1 and Figure 2, fitting seat 7, pump shaft 3 and the impeller 5 of the hollow that it comprises bearing housing 1, mechanical seal device 2, the pump housing 4, connect firmly with the pump housing 4, pump shaft 3 is loaded on the bearing housing 1 by bearing 6, pump shaft 3 one ends are fixed with impeller 5, impeller 5 is positioned at the pump housing 4, the front-end face of the sealing seat 9 of mechanical seal device 2 is connected with the rear end of fitting seat 7, and the pump housing 4 is connected with bearing housing 1, and described mechanical seal device 2 also comprises rotating ring, stationary ring, axle sleeve etc.Because the mechanical seal device 2 of existing recycle pump is fixed on the rear end of fitting seat 7; Because mechanical seal device 2 is easily damaged parts, need to be with bearing housing 1, the pump housing 4 and impeller 5 complete removals when maintenance, take off successively pipe nipple cylindrical shell 10, impeller 5, bearing housing 1 and pump shaft 3, just can take out the mechanical seal device 2 on the pump shaft 3, inconvenience very, for large-scale recycle pump, consuming time more than two days, not only waste a large amount of manpowers and time, also strengthened the maintenance difficulty.
The model utility content
The purpose of this utility model just is to provide a kind of just maintenance formula recycle pump that can make things convenient for the workman to overhaul, save the repair time.
To achieve these goals, the technical solution adopted in the utility model is such: a kind of formula recycle pump that just overhauls, fitting seat, the impeller of the hollow that comprises bearing housing, mechanical seal device, pump shaft, the pump housing, connects firmly with the pump housing, pump shaft is loaded on the bearing housing by bearing, pump shaft one end is fixed with impeller, impeller is positioned at the pump housing, the pump housing is connected with bearing housing, it is characterized in that: the rear end at the pump housing is installed with mounting plate, ear end face and the mounting plate of the sealing seat of mechanical seal device connect firmly, and mechanical seal device is positioned at fitting seat.
Compared with prior art, the utility model has the advantage of: the fixed position of mechanical seal device is changed, so that whole mechanical seal device is positioned at fitting seat, like this when maintenance, only need take off impeller, mechanical seal device just can take off from pump shaft and overhaul, and has greatly saved the repair time, has reduced the maintenance difficulty.
Description of drawings
Fig. 1 is the structural representation of prior art recycle pump;
Fig. 2 is the I place partial enlarged drawing of Fig. 1;
Fig. 3 is structural representation of the present utility model;
Fig. 4 is the II place partial enlarged drawing of Fig. 3.
Embodiment
In order more to be expressly understood the purpose of this utility model, technological scheme and beneficial effect, below in conjunction with accompanying drawing the utility model is described further, but protection domain of the present utility model is not limited in following examples.
Referring to Fig. 3, Fig. 4, a kind of formula recycle pump that just overhauls of the present utility model, comprise bearing housing 1, mechanical seal device 2, pump shaft 3, the pump housing 4, weld the fitting seat 7 of the hollow that connects firmly with the pump housing 4, impeller 5, pump shaft 3 is loaded on the bearing housing 1 by bearing 6, pump shaft 3 one ends are fixed with impeller 5, impeller 5 is positioned at the pump housing 4, the pump housing 4 is bolted with bearing housing 1, be installed with mounting plate 8 in the rear end of the pump housing 4, the ear end face of the sealing seat 9 of mechanical seal device 2 and mounting plate 8 connect firmly by bolt, mechanical seal device 2 is positioned at fitting seat 7, and described mechanical seal device 2 also comprises rotating ring 21, stationary ring 22, axle sleeve 23 etc.
During maintenance, only need take off the attachment bolt of impeller 5, sealing seat 9 and mounting plate 8, just mechanical seal device 2 can be taken off from pump shaft 3 and overhaul, need not to dismantle bearing housing 1 and pump shaft 3, for large-scale recycle pump, only need less than time half a day, greatly saved the repair time, reduced the maintenance difficulty.
