Device is then fixed on grease chamber and motor room, avoids the water in the spiral case of water pump from leaking out and even penetrates into motor room, is conducive to improve this
The safety and stability of water pump.
2, step C, E, F, G are carried out simultaneously in the present invention, while to temperature, voltage, electric current and whether leak is examined
The failure that can find that water pump occurs in time is surveyed, and generates corresponding alarm, convenient for the maintenance of later stage work personnel；Meanwhile and
When switch off the pump and also can be improved safety and reduce loss.
3, the present invention is by water pump temperature during the work time, voltage and current and whether leak detects,
Ensure that water pump is constantly in normal operating conditions, if water pump generates failure, this can find event by this control method in time
Hinder and show failure cause, and make emergency reaction, for example switch off the pump, the maintenance of later stage work personnel can be facilitated, protects
Safety of life and property is protected, there is preferable safety and stability.
Detailed description of the invention
Fig. 1 is the principle of the present invention figure.
Specific embodiment
With specific embodiment, the invention will be further described with reference to the accompanying drawing, referring to Fig. 1：
The control method of this water pump comprises the following steps：
A, starting and self-test：Start the control system in the controller being electrically connected with water pump, then passes through temperature sensor
Detect temperature it is whether normal, if temperature is abnormal, start-up temperature alarm be then shut off control system, if temperature normally if
It is whether normal that voltage is detected by voltage sensor；If voltage is abnormal, starts voltage alarm and is then shut off control system,
If voltage normally if by leakage sensor detect water pump grease chamber and motor room whether leak, start leak if leak
Alarm is then shut off control system, normal to start water pump if water-tight.
B, it operates normally：Water pump works normally.
C, temperature detection：Detect upper bearing (metal), the lower axle of water pump when water pump works normally by temperature sensor in real time
It holds with whether the temperature of three-phase coil is abnormal, if temperature anomaly, by controller judgement, whether temperature is gone beyond the limit of at this time
Value, if temperature is less than limiting value at this time, start-up temperature alarm if having exceeded limiting value, switches off the pump.
E, voltage detecting：Whether the voltage for detecting water pump by temperature sensor in real time when water pump works normally is different
Often, if electric voltage exception, by controller judgement, whether voltage goes beyond the limit of value at this time, if voltage is less than the limit at this time
Value, then start voltage alarm, if going beyond the limit of value, switch off the pump.
F, current detecting：Whether the electric current for detecting water pump by current sensor in real time when water pump works normally is different
Often, if current anomaly, starting current alarm is then shut off water pump and closes control system.
G, leak water detdction：Water pump work normally when in real time by leakage sensor detect water pump whether leak, such as
There are drainages for fruit, then start water leakage alarm, are then shut off water pump and close control system.
D, restart and close：Judge whether to need to close control system, if it is not required, then jumping back to system in step A
The just self-test link after starting, restarts self-test；If it is required, then closing control system.
Further, in step C or step E, when start-up temperature alarm or after voltage alarm, continue after 10s temperature or
Voltage is still abnormal, and controller switches off the pump；If abnormal is some phenomena, it is certain to disappear in 10s, if continued
Abnormality is still maintained after 10s, illustrating water pump, there are failures, in order to avoid generating bigger loss, protection life and property
Safety, switch off the pump is necessary in time.Above-mentioned steps C, E, F, G are carried out simultaneously, while to temperature, voltage, electric current
And whether leak carries out detecting the failure that can find that water pump occurs in time, and generates corresponding alarm, convenient for later stage work
The maintenance of personnel；Meanwhile it switching off the pump in time also and can be improved safety and reduce loss.Above controller is after breaking down
Store failure logging.
The present invention is by water pump temperature during the work time, voltage and current and whether leak detects, really
Water conservation pump is constantly in normal operating conditions, if water pump generates failure, this can find failure by this control method in time
And show failure cause, and make emergency reaction, for example switch off the pump, the maintenance of later stage work personnel can be facilitated, protected
Safety of life and property has preferable safety and stability.Controller is fixed on the shell of water pump in this control method,
Temperature sensor is mainly used for measuring the temperature of impeller and pump motor, and voltage sensor and current sensor are arranged at water
On pump motor, leakage sensor is then fixed on grease chamber and motor room, avoids the water in the spiral case of water pump from leaking out and even penetrates into motor
Interior is conducive to the safety and stability for improving this water pump.
