Abstract
The utility model provides a kind of pump circulation heater, it comprises controller, once-through cycle water pump and heater, the liquid entering hole of described heater connects motor, the liquid outlet of described heater connects described once-through cycle water pump, the temperature that described controller is sampled in described heater by PT100, once-through cycle water pump described in described controller control connection, described heater is connected to civil power by A.C. contactor, A.C. contactor described in described controller control connection.The utility model uses controller to control, and PT100 samples, and can not only realize temperature and accurately sample, and user can temperature required for egoistic needs sets itself cooling liquid; Use the once-through cycle water pump of 24V direct current supply, voltage stabilization, can ensure the working life of circulating water pump to greatest extent; Wherein, overheat protector temperature detect switch (TDS) is series between air-break switch and A.C. contactor, double insurance.
Description
Technical field
The utility model relates to engine warming up field, specifically, relate to a kind of pump circulation heater for engine warming up.
Background technique
The temperature acquisition original paper that heater on current market uses mostly is liquid and rises formula or sudden jump type temperature detect switch (TDS), and temperature sampling is poor, and can not set temperature voluntarily.The water pump that Most current heater provides is for exchanging water pump, and because water pump is large by power supply environmetal impact, if power supply voltage is unstable, then the water pump life-span can be greatly affected.Moreover the heater that Vehicles Collected from Market is sold can not show Current Temperatures, can not express water temperature in cavity intuitively, also can not estimate the heating deadline.
In order to solve above Problems existing, people are seeking a kind of desirable technical solution always.
Model utility content
The purpose of this utility model is for the deficiencies in the prior art, thus provides that a kind of structure is simple, design science, pump circulation heater practical, simple to operate.
To achieve these goals, the technological scheme that the utility model adopts is: a kind of pump circulation heater, it comprises controller, once-through cycle water pump and heater, the liquid entering hole of described heater connects motor, the liquid outlet of described heater connects described once-through cycle water pump, the temperature that described controller is sampled in described heater by PT100, once-through cycle water pump described in described controller control connection, described heater is connected to civil power by A.C. contactor and air-break switch successively, A.C. contactor described in described controller control connection.
Based on above-mentioned, this pump circulation heater also includes overheated temperature detect switch (TDS), and described overheated temperature detect switch (TDS) is series between described A.C. contactor and described air-break switch, overheated temperature detect switch (TDS) described in described controller control connection.
Based on above-mentioned, described heater be provided with sealing ring type discharge valve bottom.
Based on above-mentioned, the liquid entering hole of described heater is provided with unidirectional liquid feed valve.
The utility model hinge structure has substantive distinguishing features and progress, specifically, the utility model uses controller to control, and PT100 samples, can not only realize temperature accurately to sample, and user can temperature required for egoistic needs sets itself cooling liquid; Use the once-through cycle water pump of 24V direct current supply, voltage stabilization, can ensure the working life of circulating water pump to greatest extent; Wherein, controller controls A.C. contactor by overheat protector temperature detect switch (TDS), double insurance.
Accompanying drawing explanation
Fig. 1 is structured flowchart of the present utility model.
Fig. 2 is wiring schematic diagram of the present utility model.
Embodiment
Below by embodiment, the technical solution of the utility model is described in further detail.
As depicted in figs. 1 and 2, a kind of pump circulation heater, it comprises controller, once-through cycle water pump and heater, and the liquid entering hole of described heater connects motor, and the liquid outlet of described heater connects described once-through cycle water pump, wherein, described heater be provided with sealing ring type discharge valve bottom, liquid entering hole is provided with unidirectional liquid feed valve, and described once-through cycle water pump uses 24V direct current supply, voltage stabilization, ensure that the working life of circulating water pump to greatest extent;
Described controller is sampled by PT100 the temperature of cooling liquid in described heater, once-through cycle water pump described in described controller control connection, described controller uses Hc100 controller, by the input control of the control panel of described controller, the temperature of cooling liquid in described heater can be controlled by described controller, meanwhile, the temperature of current cooling liquid can also be shown by the display screen of described controller; Described heater is connected to civil power by A.C. contactor KM1, A.C. contactor KM1 described in described controller control connection, and described controller is connected to civil power by BAC06A type storage battery.
In order to prevent dry combustion method and overheated heater, described pump circulation heater is also provided with overheated temperature detect switch (TDS), and described controller is by A.C. contactor KM1 described in described overheated temperature detect switch (TDS) control connection, and described temperature detect switch (TDS) of crossing adopts KSD301 type temperature detect switch (TDS).
In the utility model, described once-through cycle water pump and described heater separately control, before cooling liquid is heated, under the control of described controller, described once-through cycle water pump and described heater are connected simultaneously, after cooling liquid arrives setting temperature point, control the first power-off of described heater, described once-through cycle water pump time delay power-off after 3 seconds, thus prevent cooling liquid heat from concentrating, extend the life-span of described once-through cycle water pump.
Finally should be noted that: above embodiment is only in order to illustrate that the technical solution of the utility model is not intended to limit; Although be described in detail the utility model with reference to preferred embodiment, those of ordinary skill in the field have been to be understood that: still can modify to embodiment of the present utility model or carry out equivalent replacement to portion of techniques feature; And not departing from the spirit of technical solutions of the utility model, it all should be encompassed in the middle of the technological scheme scope of the utility model request protection.
