Problems solved by technology

[0002] The long-distance pressure box culvert is used outside the shut-off device of the fast working door on the water outlet side of the pumping station. The unit, electrical equipment, and the action time and sequence of the quick working door are improperly coordinated, which may easily cause the unit to start overload or fail to start, and it is easy to cause the unit to Inversion, or even runaway, the state of the transition process deteriorates

Embodiment Construction

[0024] refer to figure 1 , a pump-valve linkage computer control method applied to pressure box culvert water delivery proposed by the present invention. During the start-up process, the motor circuit breaker is closed when the unit does not reverse, and the working door is opened after the motor enters the pumping state; During the shutdown process, the motor is turned off when the working door is closed to a small opening, that is, the working door is partially closed.

[0025] Specifically, in the present invention, the long-distance buried water delivery box culvert is installed outside the flow cut-off device on the outlet side of the low- and medium-lift pump station, and the flow cut-off device of the pump station adopts a fast working door to meet the needs of speed adjustment.

[0026] The pump-valve linkage computer control method applied to the pressure box culvert water delivery provided by this embodiment, during the start-up process, the specific steps are as fol...

Abstract

The invention discloses a pump-valve linkage computer control method applied to pressure box culvert water conveyance. The method comprises, during a start-up process, closing a motor breaker when a generator unit has no reversing rotation, and opening a work gate when an electromotor enters a water pumping state; during a close-down process, closing the electromotor when the work gate is closed to the minimum opening degree. The pump-valve linkage computer control method applied to pressure box culvert water conveyance can eliminate influence of a long-distance pressure box culvert water conveyance state on start-up and close-down of the generator unit, achieve reliable starting and stopping of the generator unit and meanwhile prolong the service life of the generator unit.

Description

technical field [0001] The invention relates to the technical field of water conservancy engineering, in particular to a pump valve linkage computer control method applied to pressure box culvert water delivery. Background technique [0002] The long-distance pressure box and culvert outside the shut-off device of the fast working door on the water outlet side of the pumping station are used for water delivery. Improper coordination of the action time and action sequence of the unit, electrical equipment, and the quick working door will easily lead to the unit starting overload or failure, and it is easy to cause the unit to fail when shutting down. Reversal, or even runaway, the state of the transition process deteriorates. Contents of the invention [0003] Based on the technical problems existing in the background technology, the present invention proposes a pump valve linkage computer control method applied to pressure box culvert water delivery. [0004] The inventio...
