Abstract
The invention relates to an electrical system with thermal protection of a pipeline pump, comprising a resistance-capacitance (RC) step-down voltage-stabilizing circuit, a silicon controlled circuit, a micro control unit (MCU) circuit and a temperature detection circuit, wherein the RC step-down voltage-stabilizing circuit supplies voltage for each circuit stably; the temperature detection circuit transmits detected temperature information to the MCU circuit; and the MCU circuit judges and controls the silicon controlled circuit to switch on or off a power supply in accordance with comparison of set information with the received information. By adopting the silicon controlled circuit, the MCU circuit controls the silicon controlled circuit to switch off the power supply in accordance with the temperature detected by the temperature detection circuit and the rate of rise in temperature, thus a water pump does not damage impellers due to the excess temperature.
Description
Technical field
The present invention relates to a kind of Circuits System, especially relate to a kind of Circuits System with tubing pump of heat protection function.
Background technology
At present; under the situation of normal use water pump; can utilize the water that drinks up to come cooling wheel and pump head, after water is drained, just not have water to cool off pump head and impeller; after water evaporation in remaining in the pump head chamber is done; the speed that the pump head temperature rises is very fast, and temperature can be very high, if at this moment there is not the heat protection; the tens seconds time to a few minutes, impeller will damage.
Summary of the invention
Technical problem to be solved by this invention provides a kind of Circuits System of the tubing pump with heat protection that can cut off the electricity supply according to the speed that temperature and temperature rise.
The present invention solves the technical scheme that its technical problem takes: a kind of Circuits System with tubing pump of heat protection, this Circuits System comprise, resistance-capacitance depressurization voltage stabilizing circuit, ghyristor circuit, MCU circuit and temperature detection circuit;
The resistance-capacitance depressurization voltage stabilizing circuit is given the stable voltage of each circuit, and temperature detection circuit is sent to the MCU circuit with the temperature information of surveying, and the MCU circuit is done contrast according to information that is provided with and the information of receiving, judgement and control ghyristor circuit switch on or off power supply.
For controllable silicon can not damaged because of overtension, described ghyristor circuit adopts the transition diode to protect controllable silicon.
The invention has the beneficial effects as follows: adopted sort circuit, the speed that the MCU circuit can rise according to the temperature and the temperature of temperature detection circuit detection is controlled ghyristor circuit and is switched on or off power supply, and water pump just can not damage impeller because temperature is too high like this.
Description of drawings
Fig. 1 is an electrical block diagram of the present invention;
Fig. 2 is a circuit diagram of the present invention.
Among the figure: 1, resistance-capacitance depressurization voltage stabilizing circuit 2, temperature detection circuit 3, MCU circuit
4, ghyristor circuit
Embodiment
A kind of as shown in Figure 1 Circuits System with tubing pump of heat protection, this Circuits System comprise, resistance-capacitance depressurization voltage stabilizing circuit 1, ghyristor circuit 4, a MCU circuit 3 and a temperature detection circuit 2;
Resistance-capacitance depressurization voltage stabilizing circuit 1 is given the stable voltage of each circuit, and temperature detection circuit 2 is sent to MCU circuit 3 with the temperature information of surveying, and MCU circuit 3 is done contrast according to information that is provided with and the information of receiving, judgement and control ghyristor circuit switch on or off power supply.
Q1 is a controllable silicon as shown in Figure 2, and U3 is an optocoupler, and transition diode D2 prevents that overtension from damaging silicon controlled.After water pump was plugged electricity, water pump was switched on, and water pump draws water.Temperature rises after water exhausts, and when temperature is raised to about 45 degree, or temperature rise rate surpasses per 5 seconds 2 and spend the duration more than 5 seconds, then disconnects water pump.
Only be concrete exemplary applications below, this protection range is not constituted any limitation.All employings are equal to the technical scheme of replacement or equivalent transformation form, all drop within this claimed scope.
