Description
Technical field
The utility model relates to the pump technology field, is specifically related to a kind of adjustable flow water pump.
Background technique
Water pump all has a wide range of applications in the national economy every field, and along with the sustainable development of national economy, people are more and more higher to the requirement of the service behaviour of water pump.
Present automobile fire is one of accident the most heavy in the road traffic accident, and it has not only caused serious economic loss, also directly injures people's life safety, bus particularly, densely populated, in case bus breaking out of fire accident, loss will increase greatly.
Just simply be equipped with fire extinguisher on traditional car, when bus in fire disaster occurs, the defectives such as untimely, the outmoded inefficacy of equipment, the scarce capacity of putting out the fire generally all can appear reacting, and Extinguisher in the market is to adopt manual small powder fire extinguisher basically, there are the technological deficiencies such as environmental pollution, effective date weak point in the extinguishing powder that powder-type fire extinguisher uses, and because the working pressure container is stored, the extinguishing agent loading amount is limited, can't satisfy the needs of the automobile condition of a fire.
Use liquid extinguisher, because extinguishing agent dosage is limited, the sprinkling of need to according to circumstances limiting the quantity of is so need a kind of water pump of capable of regulating flow quantity to spray.
The model utility content
The utility model is according to the deficiencies in the prior art, is the accurate adjust flux of water pump that solves in the past, and the problem that control procedure is more loaded down with trivial details, complicated provides a kind of adjustable flow water pump, can control accurately the flow quantity that of water pump drain pipe.
The utility model is achieved through the following technical solutions: a kind of adjustable flow water pump, comprise water pump, controller, frequency variator, pressure transducer, microcomputer, described pressure transducer is arranged on the drain pipe of water pump, described water pump, frequency variator, pressure transducer are connected with controller by circuit, and described controller is connected with microcomputer.
As the improvement of above-mentioned adjustable flow water pump, described water pump drain pipe is provided with flow probe, and described flow probe is connected with controller.
As the improvement of above-mentioned adjustable flow water pump, described controller is programmable logic controller (PLC).
Improvement as above-mentioned adjustable flow water pump is provided with solenoid valve on the drain pipe of described water pump.
The beneficial effects of the utility model: the utility model has solved the out of contior problem of usual water pump liquid outlet quantity, but the starting time of automatic digital control water pump, toggle speed, and go out the operation frequency that pump motor is regulated in the variation of hydraulic coupling and flow automatically according to water pump, improve the convenience of the operation of pump, be specially adapted to the quantitative injection of vehicle-mounted liquid inactivator.
Description of drawings
Fig. 1: the structural framing figure of adjustable flow water pump of the present utility model.

Embodiment
By describing technology contents of the present utility model, structure characteristics in detail, realized purpose and effect, below in conjunction with mode of execution and cooperate that accompanying drawing is detailed to give explanation.
Existing Extinguisher is because the technological deficiency of itself and the limitation of Environmental Conditions, automobile fire generation and particularity are lacked effective disposing capacity, and lack the ability that a kind of timely discovery is in time processed, make people's life safety and property when fire occurs, all be subject to great threat.
The manual small powder fire extinguisher of existing employing, there are the technological deficiencies such as environmental pollution, effective date weak point in the extinguishing powder that powder-type fire extinguisher uses, and because the working pressure container is stored, the extinguishing agent loading amount is limited, can't satisfy the needs of the automobile condition of a fire, and the requirements such as that fire extinguisher does not satisfy is shockproof, high temperature resistant, wet-heat resisting, in case meet the bus breaking out of fire, fire extinguisher can't be brought into play effectiveness.When implementing, in case dry powder doses is sucked by the car engine air admittance mouth, can produce serious infringement to motor, the air-conditioning system of the automobile that sucks also will cause system to turn round, and the dry powder doses of ejection can reduce the oxygen content in the car body, cause trapped personnel to breathe, cause larger economic loss.
Use liquid extinguisher can avoid above problem, the utility model provides a kind of accent flow water pump, is used the liquid extinguisher sprinkling of need to according to circumstances limiting the quantity of.
See also Fig. 1, as shown in Figure 1, a kind of adjustable flow water pump 2, comprise water pump 2, controller 1, frequency variator, pressure transducer 3, microcomputer 5, described pressure transducer 3 is arranged on the drain pipe of water pump 2, described water pump 2, frequency variator, pressure transducer 3 are connected with controller 1 by circuit, and described controller 1 interconnects with microcomputer 5.Described pressure transducer 3 gathers the pressure of the drain pipe of water pump 2, and hydraulic pressure value transferred to controller 1, controller 1 with data transmission to microcomputer 5, the control parameter that controller 1 transmits according to microcomputer 5, by the frequency control of motor speed of frequency variator realization water pump 2 motors, thus the liquid outlet quantity of regulating water pump 2.
As a preferred embodiment of the present utility model, above-mentioned controller 1 can be selected FPGA control (PLC), Digital PID Algorithm is adopted in regulation and control to hydraulic pressure, both improved the speed of response of device, and had and avoid producing excessive hyperharmonic vibration: control it and also can adopt single-chip microcomputer or other controllers.
As a preferred embodiment of the present utility model, described water pump drain pipe also is provided with flow probe 4, and described flow probe 4 is connected with controller 1.Detect liquid measure and data value is sent to controller 1, control it and feed back to microcomputer 5.
