Description
Technical field
The invention is related to a kind of shaftless sewage pump of whirling well automatic control, belongs to sewage lifting pump technical field.
Background technology
At present, sewage pump is mostly long-shaft liquid formula, some uses self priming pump pattern.
Long-shaft liquid formula has more pump shafts to be connected by spindle device below pump seat, and be equipped with guide bearing body and
Sliding bearing, while also need to assembling shield central siphon and pump shaft is protected.Operationally, since pump shaft is longer, swing nature compared with
Greatly, cause sliding bearing abrasion very fast, it is necessary to often repair.Since part is more, it is desirable that precision is high, is just needed in checking maintenance
Substantial amounts of professional technician, adds operating cost, also reduces construction efficiency.
The generally use of self priming pump pattern is strong self-priming, equipped with vacuum extractor is aided in, due to containing impurity particle in sewage,
Sealing is easy to abrasion gas leakage, causes vacuum extractor that can not work normally.In addition, being limited by atmospheric pressure, well depth is more than 8 meters
When, Strong self priming pump is also not suitable for using.
Since shaftless sewage pump is simple in structure under Full Automatic Liquid, it is unlimited to aspirate depth, there is operation stability height, inspection
It repaiies convenient disassembly, assemble the advantages such as simple, widely applied and pushed away in the whirling well device of the industries such as metallurgy, steel in recent years
Extensively.
The content of the invention
The invention technical problems to be solved are to provide a kind of shaftless sewage pump of whirling well automatic control, the elevator pump
It is unlimited to aspirate depth, operation stability is high, overhauls convenient disassembly, assembles simply, meets safe and efficient essential requirement.
To solve problem above, the specific technical solution of the invention is as follows：A kind of shaftless sewage of whirling well automatic control carries
Pump is risen, is mainly made of support tube and the pump housing, impeller is equipped in middle pump body, pump housing bottom is equipped with hydraulic motor, hydraulic motor
Output axis connection impeller center set impeller axle bottom, impeller axle top is connected with sliding bearing；Shell above its middle pump body
Body is blower inlet casing, and blower inlet casing inner cavity is equipped with diversion trench；Medium inlet is arranged with below blower inlet casing, impeller is equipped with to enter with medium
Mouth flow-guiding channel corresponding with water conservancy diversion groove location.
The blower inlet casing is prominent arcuate structure in diversion trench correspondence position.
The blade of the impeller is located at the latter half of impeller.
The top half on-bladed of the impeller, and top half surface is arc.
The hydraulic motor is connected by hydraulic fluid pipeline with the hydraulic pump that earth's surface is set, hydraulic pump input terminal and hydraulic pressure
Petrol station connects, and the control terminal of hydraulic pump is connected with hydraulic control system, while hydraulic control system is connected with electric control box.
Pressure switch is set at the support tube outlet, and pressure switch is connected with electric control box.
The hydraulic motor shaft bottom sets balancing device.
The cooperation of the guide trough structure and blade wheel structure of the shaftless sewage pump blower inlet casing of the whirling well automatic control is formed perfect
Flow-guiding channel, while using support tube instead of original multistage pump shaft and multi-point support mechanism, ensure that whole pump is steady in a long-term
Operation, while reduce breakdown maintenance point, service life is greatly prolonged, more improves the efficiency of assembling of skilled worker.
Blower inlet casing is prominent arcuate structure in diversion trench correspondence position, and the blade of impeller is located at the latter half of impeller,
The top half on-bladed of impeller, and top half surface is arc, and streamline flow passages are formed together with blower inlet casing, reduce gas
Erosion.
Hydraulic motor is connected with hydraulic pump, hydraulic oil unit and hydraulic control system, at support tube outlet pressure is set to open
It closes, elevator pump is made to realize integral self-control, scene is made to cancel pump startup switch board, start and stop all devices can be changed according to liquid level, also
Live operating status can be sent to Central Control Room, realize full automation operation.
Automatic control refers to pump discharge band pressure switch, if blocked inlet, gas leakage or evacuation, pump discharge pressure will reduce,
Fault-signal is passed to by Master Control Room, and hard stop by pressure switch, avoids the occurrence of dry grinding phenomenon.
