Abstract
The invention discloses a frost crack prevention control system of a water pump and a control method of the control system. Liquid in the water pump is frozen due to a cold weather in winter, the volume of the liquid expands after the liquid is frozen, thereby resulting in the frost crack of the water pump. The control system is characterized in that a first normally closed solenoid valve is arranged on a water inlet side of the water pump; a fourth normally closed solenoid valve is arranged on a water outlet side of the water pump; a water inlet side three-way pipe is arranged between the first normally closed solenoid valve on the water inlet side and the water pump; a middle outlet of the water inlet side three-way pipe faces upwards and is connected with a first pipeline; a second normally closed solenoid valve is arranged at the tail end of the first pipeline; a water outlet side three-way pipe is arranged between the fourth normally closed solenoid valve on the water outlet side and the water pump; a middle outlet of the water outlet side three-way pipe faces downwards and is connected with a second pipeline; a third normally closed solenoid valve is arranged at the tail end of the second pipeline; and all the normally closed solenoid valves and the water pump are connected with a singlechip control system respectively. With the adoption of the control system and the control method, the liquid in the water pump can be drained automatically after the water pump is used, and the purpose of the frost crack prevention of the water pump is achieved.

Technical field
The present invention relates to the water pump control system, specifically the anti-bursting by freezing control system of a kind of water pump and controlling method thereof.
Background technique
Winter, the liquid in the water pump can freeze owing to cold weather, and volumetric expansion after liquid freezes causes the water pump bursting by freezing.At present the antifreeze cracking method of water pump mainly contains: 1. water pump is installed in indoor, but under the actual conditions mostly inconvenience be installed in indoor; 2. the defroster that can generate heat is placed on the outside of water pump body, but defroster self will be connected power supply, consumed power for a long time; 3. at the two ends of water pump drain valve is installed, but is all needed manually to go to open at every turn.
Summary of the invention
Technical problem to be solved by this invention is to overcome the defective that above-mentioned prior art exists, the anti-bursting by freezing control system of a kind of water pump and controlling method thereof are provided, after it can finish in each use of water pump, automatically the water emptying in the water pump, thereby reach the anti-bursting by freezing purpose of water pump.
For this reason, the technical solution used in the present invention is as follows: a kind of water pump is prevented the bursting by freezing control system, comprises water pump, and it is characterized in that: the influent side of described water pump is provided with first normally closed solenoid valve, and the water outlet side of water pump is provided with the 4th normally closed solenoid valve; Be provided with the influent side three-way pipe between first normally closed solenoid valve of influent side and water pump, the central exit of this influent side three-way pipe and connect first pipeline is provided with second normally closed solenoid valve at the end of first pipeline up; Between the 4th normally closed solenoid valve of water outlet side and water pump, be provided with the water outlet side three-way pipe, the central exit of this water outlet side three-way pipe down and connect second pipeline, end at second pipeline is provided with the 3rd normally closed solenoid valve, and all normally closed solenoid valves are connected with a single-chip computer control system respectively with water pump.
Further, the distance of described the first, the 4th dried up pump of normally closed solenoid valve is preferably 30-50 centimetre, and convenient the installation after water pump is stopped using, reduced the water accumulating volume that pump two side pipe domestic demands will be discharged.
Further, the length of described first, second pipeline is preferably 10-20 centimetre, the convenient installation, and reduce and need the water accumulating volume of discharging in the pipe.
Further, the pipeline of described water pump influent side is than the high 3-5 of pipeline ° of water outlet side, because tilting action after water pump is stopped using, can make things convenient for the ponding in the pump to discharge.
The present invention also provides the controlling method of the anti-bursting by freezing control system of above-mentioned water pump, it is characterized in that, when needing water, start water pump by single-chip computer control system, automatically open first normally closed solenoid valve and the 4th normally closed solenoid valve, close second normally closed solenoid valve and the 3rd normally closed solenoid valve, influent side begins water inlet; When finishing water, close first normally closed solenoid valve and the 4th normally closed solenoid valve automatically, open second normally closed solenoid valve and the 3rd normally closed solenoid valve to discharge the water in the water pump, reach the purpose of anti-bursting by freezing.
The present invention can reach the anti-bursting by freezing purpose of water pump automatically the liquid emptying in the water pump after each use of water pump finishes; Simple, convenient.
