Abstract
The utility model discloses a vertical long-shaft sea water pump which solves the problem that the lubricating effect of guide bearings is affected due to the fact that gases exist in inner connecting pipes of existing vertical long-shaft sea water pumps. The vertical long-shaft sea water pump comprises an inner connecting pipe and a pump cover plate and a stuffing box body which are installed on the inner connecting pipe, and a gas exhaust device which can exhaust gases inside the inner connecting pipe is arranged between the pump cover plate and the stuffing box body. According to the vertical long-shaft sea water pump, gases existing inside the inner connecting pipe are exhausted quickly through the gas exhaust device, so that the lubricating effect of guide bearings is guaranteed.
Description
Technical field
The utility model relates to field of fluid machinery, is specially a kind of vertical major axis sea water pump.
Background technique
The main effect of the inner connecting tube of vertical major axis sea water pump is protection axle and guide bearing, and external clean water is lubricated all guide bearings by stuffing box body, inner connecting tube.Yet, as shown in Figure 2, there is gas the inner connecting tube inside of existing vertical major axis sea water pump, there is a large amount of gas particularly large-scale vertical major axis sea water pump inner connecting tube inside, if can not discharge the gas that has fast smoothly, the gas of retaining can increase the lubricated water resistance by inner connecting tube from top to bottom, thereby influences the lubrication effect of guide bearing, and serious situation can burn out guide bearing.
The model utility content
In order to have gas in the inner connecting tube that overcomes existing vertical major axis sea water pump, influence the deficiency of guide bearing lubrication effect, the utility model aims to provide a kind of vertical major axis sea water pump, this sea water pump is provided with venting gas appliance, can promptly the gas that exists in the inner connecting tube be discharged, guarantee the lubrication effect of guide bearing.
To achieve these goals, the technological scheme that adopts of the utility model is:
A kind of vertical major axis sea water pump comprises inner connecting tube, is contained in pump closure and stuffing box body on the inner connecting tube; Its structural feature is to be provided with the venting gas appliance that can discharge gas in the inner connecting tube between described pump closure and the stuffing box body.
Below be the technological scheme of further improvement of the utility model:
According to embodiment of the present utility model, described venting gas appliance comprises the ring-type shrouding that is arranged between pump closure and the stuffing box body, and this ring-type shrouding and described inner connecting tube, pump closure, stuffing box body form air cavity; On the described ring-type shrouding outlet valve that is communicated with described air cavity is housed.
Be provided with seal ring between described inner connecting tube and the pump closure, preferably adopt the O RunddichtringO, can will separate inside and outside the inner connecting tube thus, prevent from pumping medium and enter in the inner connecting tube.
Compared with prior art, the beneficial effects of the utility model are: the utility model adopts automatic control pressure vent that the gas that inner connecting tube accumulates is discharged, and is simple in structure, guaranteed the lubrication effect of guide bearing.
Below in conjunction with drawings and Examples the utility model is further elaborated.
