Abstract
The utility model discloses an embedded intelligent water pump protector. One end of the water pump protector is connected with a neutral wire and a live wire, and an output wire at the other end of the water pump protector is connected with a motor winding coil; a power module, a control unit, a contact switch and a sensor are arranged in the protector; the contact switch is connected in series to the live wire and is connected with the control unit; a microprocessor and an auxiliary circuit of the microprocessor are arranged in the control unit; the power module is bridged between the neutral wire and the live wire; the control unit is connected with the power module and the sensor respectively; and the water pump protector is positioned above a motor armature in a water pump shell. Compared with the prior art, the embedded intelligent water pump protector has the advantages that the operation situation of the water pump can be automatically judged according to the operation state of a motor, whether the water pump motor operates normally is detected to fulfill the aim of protecting and automatically controlling the water pump, the defects in the prior art are overcome, and the protector and a water pump are combined into a whole, so that the external wiring difficulty and the maintenance difficulty of non-specialized persons are reduced, and convenience and applicability are guaranteed.
Description
Technical field
The utility model relates to a kind of water pump protector, relates in particular to a kind of embedded intelligent water pump protector.
Background technique
In the market water pump or motor run into voltage functuation through regular meeting in daily use, factor affecting such as load variations, thus reduce water pump or motor working life even cause damage of product.Current water pump or motor automatic holding device all are to control with the electric current, the voltage that detect water pump, and this method accuracy rate is not high enough, can not be effectively protection be effectively and timely played comprehensively in the stall of water pump, zero load, low voltage running etc.
The model utility content
The purpose of the utility model is to provide a kind of accuracy rate the high and convenient embedded intelligent water pump protector of installing, reducing the external cabling difficulty, solves the shortcoming that existing technology exists.
The utility model adopts following technological scheme to realize:
A kind of embedded intelligent water pump protector; It is characterized in that; Said water pump protector one end connects zero line and live wire, and the output line of the other end connects machine winding coil, comprises power module, control unit, contact-making switch and sensor in the protector; Said contact-making switch is connected on the live wire and with control unit and links to each other; Be provided with microprocessor and auxiliary cicuit thereof in the said control unit, said power module is connected across between zero line and the live wire, and said control unit links to each other with sensor with power module respectively.
Further, said water pump protector is positioned at the top of the armature of water pump casing.
The useful technique effect that the utility model possesses is:
Whether normally the microprocessor of controller inside is judged the operation conditions of water pump automatically according to the operating condition of motor, detect pump motor operation, to reach the purpose of protection and automatically controlled water pump, overcomes the deficiency of existing technology; Protector and water pump are combined into one, and reduce external cabling difficulty and layman's maintenance difficulties, convenient should using.
Description of drawings
Fig. 1 is the circuit block diagram of embedded intelligent water pump protector.
Embodiment
Through facing embodiment's description down; To help public understanding the utility model more; But can't the concrete embodiment that the claimant is given be regarded as restriction to the utility model technological scheme, any definition to parts or technical characteristics change and/or to overall structure do form but not the conversion of essence all should be regarded as the protection domain that technological scheme limited of the utility model.
The preferred embodiment of the utility model as shown in Figure 1; Embedded intelligent water pump control protector is made up of housing, circuit board, control unit and magnet cover; Be positioned at the top of the armature of water pump casing, be installed on motor internal and be connected end connection zero line N and live wire L with the electric power incoming line of motor; The output line of the other end connects machine winding coil; Comprise power module, control unit, contact-making switch and sensor in the protector, contact-making switch is connected on the live wire and with control unit and links to each other, and is provided with microprocessor and auxiliary cicuit thereof in the control unit; Power module is connected across between zero line and the live wire, and control unit links to each other with sensor with power module respectively.The effect of power module is to convert external Ac (civil power) into controller inner needed voltage, ensures the proper functioning of other unit; Control unit is made up of microprocessor that customizes function certainly and auxiliary cicuit, and main effect is to carry out analysing and processing to the signal that sensor sample obtains, and control unit is judged the work at present state automatically; Whether be in proper functioning; Or overload, or idle running, or superpressure is unusual.When machine operation during in abnormal condition, controller is controlled the contact-making switch deenergization automatically, thus the protection motor.
The magnet of on the collar bush of motor, making in advance; Sensor in the water pump protector is transferred to the inside micro processor to the working state signal of water pump; The inner microprocessor of controller will judge automatically whether pump working is normal, if normally will work on, when brownout or pump motor are in stall, idling conditions; Controller will cut off the power supply of motor automatically, thereby effectively protects water pump.This product need not debugging and can use, and has easy for installationly, and reliability is high, and cost is low, can play very effective protective action to the motor of water pump.Further, product can change to arbitrary rule or irregularly shaped according to the mechanical profile of water pump or motor.Protector can be changed parameter to adapt to the motor and water pump that is used for different capacity, all can satisfy overload, zero load, stall, protection such as change in voltage requirement.The embedded intelligent water pump protector of the utility model can directly be controlled the operation of motor effectively, protects the motor of water pump rapidly.The characteristics of protector are to be installed on water pump inside, and directly are connected with motor coil, can be the present not available characteristics of all controllers according to the working state controlled in real-time motor of motor.
Certainly; The utility model can also have other various embodiments; Under the situation that does not deviate from the utility model spirit and essence thereof; Those of ordinary skill in the art can make various corresponding changes and distortion according to the utility model, but these corresponding changes and distortion all should belong to the protection domain of the appended claim of the utility model.
Claims (2)
