Abstract
The utility model relates to structural improvement of a novel double entry pump which comprises a pump body, a pump bonnet, a shaft and an impeller and is characterized in that the pump body is a horizontal split-case pump body; an inlet is arranged at the left side of the pump body; an outlet is arranged at the upper part of the pump body; a spigot is arranged at the fit joint of a packing shaft sleeve and a short shaft sleeve on the shaft to position the packing shaft sleeve and the short shaft sleeve; an VS oil seal is arranged at the outside of the sealing joint of a bearing body and the short shaft sleeve; and the pump feet are connected with the pump body through bolts. The novel double entry pump is characterized in that a sealing ring is positioned on the pump case through two bolts. The novel double entry pump has the advantages that the double entry pump is convenient to maintain and more reasonable in structure, the directions of the inlet and the outlet of the pump can be changed and a customer is convenient to choose.
Description
Technical field
The utility model relates to a kind of double suction pump, particularly a kind of improvement of novel double suction pump structure.
Background technique
Conventional double suction pump (as Fig. 1): be horizontal middle open type.Pump turnover bore enters a left side and goes out for be seen as the right side from drive end; Packing sleeve and short sleeve cooperation place do not have step, and O type circle sealing part is difficult to seal water like this; The bearing support sealing part is because of being the labyrinth slot type, and thin oil is difficult to seal to such an extent that live, and dust easily invades in the bearing body cavity, and then has influenced the whole service of water pump; Pump pin and pump housing one can not change the size of its pin; The paraxial place of tail end bearing support does not hole, inconvenience when transferring the crack; Seal ring is straight cylinder ring, only depends on a screw not locate well.
Summary of the invention
The purpose of this utility model is to solve existing the problems referred to above of conventional double suction pump in the prior art, and a kind of improvement of novel double suction pump structure is provided.The utility model designs the improvement of novel double suction pump structure, comprise the pump housing, pump cover, axle, impeller, it is characterized in that: the pump housing is horizontal middle open type, inlet is positioned at pump housing left side, outlet is positioned at the top of the pump housing, there is the seam location packing sleeve on axle and short sleeve cooperation place, are added with the VS oil sealing outside bearing support and short sleeve sealing part, and the pump pin is to be connected by bolt with the pump housing.It is characterized in that: seal ring is positioned on the pump case by two screws.The utility model has the advantages that novel double suction pump is easy to maintenance, more reasonable structure, pump is imported and exported the direction change, makes things convenient for customer selecting.
Description of drawings
The cross-sectional view of accompanying drawing 1 prior art,
Accompanying drawing 2 is a positive cross-sectional view of the present utility model,
Accompanying drawing 3 is an exterior lateral sides structural representation of the present utility model,
Below in conjunction with drawings and Examples the utility model is elaborated,
Embodiment
Comprise the pump housing 1, pump cover 2, axle 3, impeller 4 among the figure, it is characterized in that: the pump housing 1 is horizontal middle open type, import 5 places are positioned at the pump housing 1 left side, outlet 6 is positioned at the top of the pump housing 1, packing sleeve 7 on axle 3 has the seam location with short sleeve 8 cooperation places, be added with VS oil sealing 10 outside bearing support 9 and short sleeve 8 sealing part, pump pin 11 is to be connected by bolt 14 with the pump housing 1.It is characterized in that: seal ring 12 is positioned on the pump housing 1 shell by two screws 13.
Improving after the double suction pump structure also is horizontal middle open type.Pump turnover bore advances out for being seen as a left side from drive end, as rotor is transferred a size, also can be to go out on the right side is advanced; There is seam location packing sleeve and short sleeve cooperation place, at stop portion the O type circle of cooperation are arranged, and O type circle has just been strengthened the sealing effect of this sealing part like this; Bearing support and short sleeve sealing part add the VS oil sealing, so just seal the leakage of oil and the intrusion of dust well; The pump pin is to be connected with bolt with the pump housing, changes a support as long as change the size of pin like this, does not need the pump housing to repair a die; The paraxial place boring of tail end bearing support, also very convenient when transferring crack, maintenance; Seal ring cooperates with pump case and changes two screws location into, locatees more stable.
Claims (2)
1. the improvement of novel double suction pump structure, comprise the pump housing, pump cover, axle, impeller, it is characterized in that: the pump housing is horizontal middle open type, inlet is positioned at pump housing left side, outlet is positioned at the top of the pump housing, and there is the seam location packing sleeve on axle and short sleeve cooperation place, and the O type circle of cooperation is arranged at stop portion, be added with the VS oil sealing outside bearing support and short sleeve sealing part, the pump pin is to be connected by bolt with the pump housing.
