The underwater major axis pump comprises a water inlet section, a radial guide vane, a middle section, a space guide vane, a protective pipe, a connecting pipe, a transmission shaft, a drain pipe, a jet pipe, a balance pipe, water level detection probes and a diving electromagnetic valve, wherein the water inlet section, the radial guide vane, the middle section and the space guide vane are combined, connected through a draw-in bolt and compressed to form a water pump cavity; and the water pump cavity, an impeller arranged in the water pump cavity, an impeller nut, a locating ring, a pump shaft and a mechanical seal are assembled together to form a decompression chamber. The underwater major axis pump is unique in design and good in use effect, completely solves the sealing problem of the conventional rolling bearing structural space guide vane underwater major axis pump, and the problem that air is expanded and cannot be discharged due to operation of a bearing and a shaft seal, enables a water pump to realize a circulated automatic liquor drainage function, prolongs the service lives of the mechanical seal and a rolling bearing, improves safety, reliability and service life of a pump package, and reduces maintenance cost of the water pump.
Description
Technical field
The utility model relates to a kind of major axis pump, relates in particular to a kind ofly with major axis pump under the liquid of jet rows liquid device, belongs to the electromechanical equipment technical field.
Background technique
Under present existing rolling bearing structure formula spatial guide blade liquid in the major axis pump, between spatial guide blade, pillar and connecting tube, be provided with rolling bearing assembly, this rolling bearing assembly adopts seal with O ring to cooperate with the spatial guide blade upper end, the rolling bearing bottom is provided with outside framework oil seal, and rolling bearing assembly and lower end, spatial guide blade cooperation place are provided with outside framework oil seal and black box.This kind bearing unit places the spatial guide blade upper end, has increased the jib-length of pump shaft between impeller and bearing, has reduced the stiffness of pump shaft.In the process of water pump at high speed operation, the swing of impeller and pump shaft is very big, thereby causes the damage of rolling bearing assembly, influences the normal use of water pump, reduces the working life of water pump.Take place because water pump O shape circle and black box in long-term using process have failure phenomenon, this medium that can cause water pump to be pumped enters in the rolling bearing assembly, destroys the working environment damage bearing of rolling bearing; Add exhaust port is not set on the bearing unit, during water pump operation, the heat that black box and bearing produce can make the air in the pillar expand, can't discharge pillar, thereby increase the weight of to influence the sealability of water pump and the working life of bearing, influence the normal use of water pump, in the working life of having reduced water pump, increased the maintenance cost of water pump.
Summary of the invention
The purpose of this utility model is to overcome the deficiency in the problems referred to above, and major axis pump under the liquid of a band jet rows liquid device is provided.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of with major axis pump under the liquid of jet rows liquid device, comprise inlet segment, radially stator, stage casing, spatial guide blade, pillar, connecting tube, transmission shaft, liquid-discharging tube, jet pipe, balance tube, water level detecting probe and diving solenoid valve, inlet segment, radially stator, stage casing and spatial guide blade are combined, connect and compress by turnbuckle, form the pump chamber of water pump; The formation relief chamber is assembled in the impeller, impeller nut, positioning ring, pump shaft and the mechanical seal that arrange in pump chamber and the pump chamber jointly.
Pillar, connecting tube cooperatively interact the back with Bolt Connection with spatial guide blade, bearing support, pump holder respectively and compress, and form independently water-supplying chamber's runner;
Transmission shaft places in the pillar, compresses with bearing gland; Liquid-discharging tube inserts in the liquid jetting device and fixes; Jet pipe is fixed on the vent; Balance tube is fixed on the water pipe mounting hole; The lead of water level detecting probe and diving solenoid valve is connected with PLC programmable controller in the water pump central station of floating dock by armoured conduit.
The utility model design is ingenious, using effect good, has solved sealing problem and bearing and a problem that the envelope operation causes air to expand and can not discharge of major axis pump under the existing rolling bearing structure formula spatial guide blade liquid fully; Can make water pump realize circulation automatic drain function, prolong the working life of mechanical seal and rolling bearing, in the working life of having improved safety reliability and the pump group of pump group, reduce the maintenance cost of water pump.
