Description
Technical field
The present invention relates to a kind of water pump control method and device.
Background technology
Tradition pump control unit mode: being the outlet installation pressure transducer at water pump, when water tank full water state, float valve is closed, and in water pipe, pressure increases to certain value, and pressure switch disconnects, and water pump also quits work. There is a lot of drawback in this control method, pressure valve in water contact, corrosion and water stain problem, causes that the pressure valve life-span is not long for a long time, having impurity if also had in water, can affect the tightness of pressure valve, causes that valve damages cisco unity malfunction. Owing to being pressure valve control, the change of water pressure, for instance user turns on the tap, or water tower water somewhat less, or pipe leakage, pressure is also just little, and pressure valve will automatically turn on water pump, and such water pump can frequently switch on. The water pump life-span is made to be greatly shortened. Owing to pressure valve contacts with water for a long time, so the life-span is comparatively short, user needs to make professional personnel carry out keeping in repair, install and debugging, and the used time is it is generally required to more than 2 hours. In unattended situation, if pressure valve breaks down, or pressure valve is blocked by the impurity in water, and water pump will work always, hot, until burning, buries huge hidden danger to potential safety hazard.
Another kind is placement high-low water level sensor in water tank, must install from water tank to water pump location with wire, when low water level sensor is opened time, water pump just automatically begins to work, during high water level, sensor is shut off water pump, the wiring of this control mode is loaded down with trivial details, trouble is installed, need electrician and water conservancy project to construct simultaneously, and when building construction, will pre-buried control line, a lot of finished houses bought are cannot realize pre-buried, this control mode is installed and loaded down with trivial details, if maintenance does not have building construction drawing to have no way of doing it especially, current consumption is considerably less, the personnel of 2 people specialty install and minimum need time half a day. if level sensor breaks down, or state of cutting off the water, water pump will work always, if unmanned, water pump will burn, and takes electricity, water wasting, also buries disaster hidden-trouble.
In invention
The technical problem to be solved in the present invention is to provide a kind of new water pump control method and device.
For solving the problems referred to above, the technical solution used in the present invention includes:
1) obtain the temperature of current water pump vane or spiral case position, and compare with ambient temperature;
2) when the temperature at water pump vane or spiral case position is less than or equal to ambient temperature, controller judges that water normally gone up by water pump;
3) when the temperature at impeller or spiral case position, more than ambient temperature and when exceeding preset value or time persistently overheating, judgement water tower is in full water or is in state of cutting off the water by controller, is automatically switched off water pump;
4) and time opening water pump function is set, the requirements set Auto On Time according to user;
Above-mentioned steps 3) described in preset value be current environmental temperature+judgement temperature.
A kind of pump control unit, realizes according to method described above, and including housing, described housing front arranges power output socket, reverse side arranges water pump temperature sensor, upper surface arranges control panel, inner chamber arranges control circuit and environment temperature sensor;
Described water pump temperature sensor is for obtaining water pump vane or the temperature at spiral case position;
Described environment temperature sensor is for obtaining the temperature of environment;
When the temperature at impeller or spiral case position is for a long time more than ambient temperature and when exceeding preset value, the output relay that described control circuit controls to be arranged in housing is cut off the electricity supply accessory power outlet power supply.
Described pump control unit, it is characterised in that: described water pump temperature sensor surface scribbles thermal conductive silicon glue-line.
Described pump control unit, it is characterised in that: described housing side arranges switch.
By the pump control unit that the water pump control method of the present invention realizes, have the advantage that
1, the temperature of current water pump vane or spiral case position is obtained, compare with ambient temperature, when the temperature of impeller or spiral case position starts to raise, and after reaching preset value higher than ambient temperature, controller will judge that water tower water is full, or being in state of cutting off the water, water pump will be automatically switched off. And design and have timing start-up function, it is possible to the requirements set Auto On Time according to user.
If 2 temperature sensors damage, or loose contact, this control system can automatically cut off out-put supply, it is ensured that water pump safety, and display lamp speed flash prompting user controls system malfunctions.
3, this device has IP33 level to protect, for instance when fortuitous event water pump water pipe explosion, and product will not be impacted by the water-sprinkling of short time. Just in case water inlet causes system failure, system will automatically cut off out-put supply.
4, this water pump control method also includes circulation timing power up function, it is possible to according to the time that user sets, Auto Power On draws water, until full water state or state of cutting off the water, is automatically switched off water pump.
5, easy for installation, as long as native system being fixed near spiral case just passable with band. Then the plug of water pump is inserted on this device. This device is inserted into civil power. Layman can complete to install and debugging in 1 minute, very convenient.

Detailed description of the invention
Embodiment 1:
A kind of water pump control method of the present invention, including:
1) obtain the temperature of current water pump vane or spiral case position, and compare with ambient temperature;
2) when the temperature at water pump vane or spiral case position is less than or equal to ambient temperature, controller judges that water normally gone up by water pump;
3) when the temperature at impeller or spiral case position for a long time more than ambient temperature or persistently overheating time, judgement water tower is in full water or is in state of cutting off the water by controller, is automatically switched off water pump;
4) and time opening water pump function is set, the requirements set Auto On Time according to user.
Above-mentioned steps 3) described in preset value be current environmental temperature+judgement temperature. Above-mentioned judgement temperature is obtained by test, and water pump is when normal operation, and the temperature at its impeller of pump or spiral case position is generally less than or equal to ambient temperature. When water tower be in full water or be in cut off the water state time, during water pump overwork 30-90 second, the temperature at its impeller or spiral case position can slowly raise, and can be higher than ambient temperature about 5 degree.
