Background technique
Current, electromechanical equipment constant pressure water supply utilizes motor frequency conversion technology to realize.But do not have the place powered that Diesel engine pump usually will be utilized to supply water to aqueduct in some remote districts, due to the change of water user's terminal water consumption, the pressure respective change in aqueduct.And the rotating speed of Diesel engine pump can not change rotating speed because of pressure change, thus constant pressure water supply cannot be realized.When hypotony, can not normal water supply; When overpressure, affect the security of operation of pump.
Summary of the invention
Technical problem to be solved by this invention is the defect for existing in prior art, provides a kind of control gear realizing Diesel engine pump constant pressure supplying water.
For solving this technical problem, the invention provides a kind of Diesel engine pump automatic constant pressure control device, include remote pressure gauge, driving controller of stepping motor, stepper motor and Diesel engine pump, described remote pressure gauge is arranged on water supply line, stepper motor and drive controller are arranged on Diesel engine pump, and driving controller of stepping motor and remote pressure gauge set up data communication; Described step motor shaft is provided with gear, match with gear and be provided with tooth bar, one end of tooth bar is provided with throttle line line ball post, one end of throttle line is fixed on throttle line line ball post, stepper motor is moved up and down by gear driven tooth bar, and the throttle line of rack drives Diesel engine pump moves up and down thus controls the throttle of Diesel engine pump.
The present invention also comprises rach slot, and tooth bar is located in rach slot, and described rach slot is fixed on Diesel engine pump.
Described throttle line is connected with tooth bar by connecting rod.
Beneficial effect: the force value that the present invention is gathered by remote pressure gauge is converted into electrical signal, driving controller of stepping motor is transferred to by signaling line, instruction is sent by controller, control step motor forward or reverse and rotation amplitude, thus make the throttle size of rack drives throttle control diesel engine, make diesel engine acceleration or deceleration, reach pump rotary speed to increase or reduce, realize the constant of hydraulic pressure in pipeline, realize constant pressure water supply, there is structure simple, easy to use, the advantage that constant voltage is effective, the constant pressure water supply from far-off regions of not power supply can be widely used in, also as the equipment of water supply for subsequent use, there are wide market prospects.
