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, and some uses self priming pump pattern.
Long-shaft liquid formula, there are 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, because pump shaft is longer, swing nature compared with
Greatly, cause sliding bearing abrasion very fast, it is necessary to often repair.Because part is more, it is desirable to which precision is high, is just needed in checking maintenance
Substantial amounts of professional and technical personnel, adds operating cost, also reduces efficiency of construction.
The typically 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 wear gas leakage, causes vacuum extractor can not normal work.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.
Because shaftless sewage pump is simple in construction under Full Automatic Liquid, it is unlimited to aspirate depth, there is operation stability height, inspection
Repair convenient disassembly, assemble the advantage 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 concrete technical scheme of the invention is as follows：A kind of shaftless sewage of whirling well automatic control carries
Pump is risen, is mainly made up of support tube and the pump housing, is provided with impeller in its middle pump body, pump housing bottom is provided with hydraulic motor, hydraulic motor
Output axis connection impeller central 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 chamber is provided with guiding gutter；Medium inlet is arranged with below blower inlet casing, impeller is provided with to enter with medium
The flow-guiding channel of mouth and guiding gutter position correspondence.
Described blower inlet casing is prominent arcuate structure in guiding gutter correspondence position.
The blade of described impeller is located at the latter half of impeller.
The top half on-bladed of described impeller, and top half surface is arc.
Described hydraulic motor is connected by hydraulic fluid pipeline with the hydraulic pump that earth's surface is set, hydraulic pump input and hydraulic pressure
Petrol station is connected, 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 described support tube outlet, and pressure switch is connected with electric control box.
Described hydraulic motor rotating shaft bottom sets bascule.
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, formed perfect
Flow-guiding channel, while original multistage pump shaft and multi-point support mechanism instead of using support tube, 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 guiding gutter 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, sets pressure to open at support tube outlet
Close, elevator pump is realized integral self-control, scene is cancelled pump startup switch board, start and stop all devices can be changed according to liquid level, also
Live running status can be sent to Central Control Room, realize that full automation operates.
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.
