Abstract
Disclosed is a shielding suspension pump, comprising a feeding pump, a driving motor, a suspension support shielding tube, a support plate, a cooling system, a lubricating oil pressurized feeding device and a sealing packing pressurized feeding device. The shielding suspension pump is characterized in that a flange at the upper end of the suspension support shielding tube is fixed on the support plate; and the feeding pump is fixed on a flange arranged at the lower end of the suspension support shielding tube. The shielding suspension pump has high suction vacuum height and high hydraulic efficiency, shortens the transmission shaft, reduces transmission power loss, improves efficiency, and eliminates the faults like wear and breaking of the shaft of a long shaft pump. Adopting the suspension support shielding tube to fix the driving motor and the feeding pump and being provided with a forced ventilation system, the shielding suspension pump can operate normally under harsh conditions of high temperature and high humidity.
Description
Technical field:
The utility model patent relates to a kind of pump, particularly relates to a kind of pump and driving machine and is suspended to the elevator pump that promotes high-temperature water on the hot and humid down-hole liquid level.
Background technique:
A kind of like this operating mode is arranged: lower the temperature in the steel slag immersion water with molten steel-refining generation in the process for producing steel and iron process of steel production enterprise.(below be called medium) contains mineral substance and solid particle in a lot of slags in this process water, and the thermal energy exchange of slag makes the medium degree up to 80～90 ℃.(vapor tension 355～525.6mm/Hg) MEDIA FLOW are sent medium back to braised slag pool by the lifting water pump that is arranged in the well again to retaining well (pond) (4～-6 meters).The lifting water pump that generally adopts in this working condition is mainly long shaft submerged pump at present, its axial length is generally about 6～10 meters, its pump housing, impeller stretch under water, drive motor is arranged on axis normal top and is positioned at abovegroundly, and the power of drive motor is passed to the lower end by major axis impeller is transported to medium the conveyance conduit on ground by lifting pipe by the rotation work done of impeller.
Because the transmission shaft of long shaft submerged pump is immersed in the medium, be loaded with the compound with the material of the relative negative charge of pump shaft material such as calcium, magnesium, sulphur, phosphorus in the medium, will inevitably be deposited on the pump shaft surface.The participation of the particle that in addition exists in the medium in pump operation can make very quick-wearing of the guide bearing of major axis pump and axle surface.Cause pump often can't normally move.Must propose maintenance this moment with pump, changes the parts that damage.
In all trades and professions with above-mentioned operating mode with pump close also have a lot, as: the boiler waste water cooling tank pumps of the eddy flow well pump in the iron and steel metallurgy enterprise, descaling pump, electric power enterprise etc., each enterprise is the problem that thoroughly solves the high maintenance difficult of long shaft submerged pump rate of fault now.All striving to find a kind of reliability and durability new pump, but all not too suitable.
As: vertical self-sucking pump, because of medium temperature height, vapor tension height, suction head very big again, when the vertical self-priming pump operation, can cause the medium vaporization, make it working efficiency and reduce even do not inhale water, the backflow road that mineral substance fouling in the medium again and impurity thing can very fast obstruction self-priming pumps causes self-priming pump normally to move.
Summary of the invention:
The purpose of this utility model provides the shielding suspension type elevator pump of a kind of heat resistance, high suction depth, below is called shielding suspension type pump.
The technological scheme that adopts is:
Shielding suspension type pump, comprise transfer pump, drive motor, pendulous support shielded-plate tube, dunnage, cooling system, lubricant oil pressurized delivered device and stuffing box packing pressurized delivered device, it is characterized in that described pendulous support shielded-plate tube upper flanges is fixed on the described dunnage, described transfer pump is fixed on the following end flange of pendulous support shielded-plate tube.
The bearing support of above-mentioned transfer pump and drive motor are arranged in the pendulous support shielded-plate tube.
Working principle:
Shielding suspension type pump overhangs transfer pump and drive motor below the ground level in design proposal, in the well more than the water line, this scheme has shortened propeller shaft length, its objective is that to overcome long shaft submerged pump axial length moment of torsion big, guide bearing and pump shaft are easy to wear, the fraud pain of fracture, in addition pump adopts the advanced hydraulic model of low net positive suction head again, increased substantially and sucted vacuum height, the utility model equipment has been had effectively overcome the medium temperature height, the vapor tension height, easily vaporization and the ability of the difficulty that can't normally move when negative pressure promotes, and can the continous-stable operation.
The advantage of the utility model patent:
Transfer pump adopts advanced hydraulic model, has very high vacuum height and the hydraulic efficiency of sucting.
Adopting the common time outstanding form of drive motor and transfer pump to shorten transmission shaft has reduced the transmission power loss and has improved efficient.
The pump impeller center line is higher than liquid level, makes not contact medium of transmission shaft, does not establish guide bearing and has stopped the wearing and tearing of major axis pump pump shaft, the class formula fault of off-axis.
Adopt pendulous support shielded-plate tube shielding fixed drive motor and transfer pump and dispose forced ventilation system, make equipment adapt to normally operation under the severe environmental conditions of high temperature, high humility.
Can realize the equipment operation automation behind true device of the shielding pump that dangles configuration and the automatic control cabinet, need not bottom valve during suction low level medium, need not self filling type and install, shut down noresidue medium in the pump chamber of back, carry the sewage of easy fouling, slag to need not backwash when starching.
