Abstract
The invention provides a water pump automatic power-off protective method and a water pump automatic power-off protective device. The water pump automatic power-off protective method comprises that work temperature is detected through a temperature probe arranged in a water pump stationary ring, when the work temperature reaches a set temperature, power of a water pump is automatically cut off and the water pump stops working. The water pump automatic power-off protective device comprises the temperature probe arranged in the water pump stationary ring. The temperature probe is connected with a center integration module. The center integration module is in signal connection with an electromagnetic switch. The electromagnetic switch is connected with a drive motor of the water pump. According to the water pump automatic power-off protective method and the water pump automatic power-off protective device, a risk that a water pump shaft seal is burnt due to over high temperature is avoided, service life of the water pump is improved, repair cost of the water pump is reduced and production efficiency is improved.
Description
Technical field
The present invention relates to mechanical field, refer to especially the guard method of a kind of water pump auto-breaking and water pump automatic power-off protection device.
Background technology
The most general structure of water pump is to adopt the mechanical shaft seal formula to prevent leak of liquid at present, and mechanical shaft seal is that a rotating ring and stationary ring cooperate motor rotation break-in to realize sealing function.This structure will certainly produce high temperature, if this temperature can not in time be taken away, concurrent dissipating will make mechanical oil seal Yin Gaowen and burn.Thereby leak of liquid in the generation pump, and cause production accident.
Present stage, people only evade the problem that high temperature causes from the change of material and shaft seal structure, but effect is undesirable, belongs to cure the symptoms, not the disease, so can not tackle the problem at its root.
Summary of the invention
The present invention proposes the guard method of a kind of water pump auto-breaking and water pump automatic power-off protection device, has solved the problem that pump seal burns easily in the prior art.
Technical scheme of the present invention is achieved in that
The guard method of a kind of water pump auto-breaking, the method is by the probe of set temperature in water pump stationary ring testing temperature, and when working temperature reached design temperature, the water pump auto-breaking quit work.
Preferably, described temp probe is connected with a control circuit, and described control circuit also is connected with an electromagnetic switch; When the working temperature that detects water pump when described temp probe surpassed described design temperature, described control circuit sent cut-offing instruction to described electromagnetic switch.
Preferably, also be connected with warning device on the described control circuit, when described control circuit sent cut-offing instruction, described warning device sent alarm signal.
Preferably, described warning device is signal lamp.
The present invention also proposes a kind of water pump automatic power-off protection device; this device comprises the temp probe that is arranged in the water pump stationary ring; described temp probe is connected with a central integration module, and described central integration module is connected with an electromagnetic switch signal, and described electromagnetic switch is connected with the drive motors of water pump.
Preferably, also be connected with warning device on the described central integration module.
Preferably, described temp probe is thermocouple and thermal resistance.
Beneficial effect of the present invention has:
1. the risk of having avoided pump seal to burn owing to high temperature is too high, the useful life of having improved water pump;
2. reduced the maintenance cost of water pump;
3. avoid pump seal to burn the shutdown that causes, improved production efficiency.
Description of drawings
In order to be illustrated more clearly in the embodiment of the invention or technical scheme of the prior art, the below will do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art, apparently, accompanying drawing in the following describes only is some embodiments of the present invention, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the syndeton schematic diagram of water pump automatic power-off protection device embodiment of the present invention.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the invention, the technical scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that obtains under the creative work prerequisite.
The present invention proposes the guard method of a kind of water pump auto-breaking, and the method is by the probe of set temperature in water pump stationary ring testing temperature, and when working temperature reached design temperature, the water pump auto-breaking quit work.Can be more specifically: described temp probe is connected with a control circuit, and described control circuit also is connected with an electromagnetic switch; When the working temperature that detects water pump when described temp probe surpassed described design temperature, described control circuit sent cut-offing instruction to described electromagnetic switch.
According to the method; the present invention further proposes a kind of water pump automatic power-off protection device; as shown in Figure 1; this device comprises the temp probe that is arranged in the pump seal stationary ring; described temp probe is connected with a central integration module; described central integration module is aforesaid control circuit, and it is connected with an electromagnetic switch signal, and described electromagnetic switch is connected with the drive motors of water pump.
The present invention needs to implant temp probe first in the water pump stationary ring, when pump working, temp probe is transferred to central integration module (or claiming control circuit) with temperature signal, critical working temperature when being provided with the pump seal damage in central integration module (or claiming control circuit) should critical working temperature be set to design temperature T.When temp probe detected the pump working temperature and reaches design temperature T, central integration module sent cut-offing instruction to described electromagnetic switch, and water pump is quit work.The scope of design temperature T among the present invention can be set as the case may be, for example can be set between the 60-200 degree.
Simultaneously, also be connected with warning device on the described central integration module, when described central integration module sent cut-offing instruction, described warning device sent alarm signal.Described warning device can be signal lamp, but also voice signal or possesses sound and light of alarm simultaneously, and other alarm device commonly used, thereby realizes the protection to water pump.
Temp probe described in the present invention can be converted into temperature signal circuit signal for the temperature sensor commonly used such as existing thermocouple and thermal resistance, so that the shutdown of control drive motors gets final product.
In actual use, it is because shaft seal high temperature burns that 95% water pump damages, and the present invention has avoided this risk of burning, and has greatly improved the useful life of water pump; In the maintenance of water pump, the shaft seal cost accounts for more than 40%, so the present invention has also reduced the maintenance cost of water pump of water pump complement basis; Because the water pump shutdown can cause stopping of production, so the present invention has also improved production efficiency.
The above only is preferred embodiment of the present invention, and is in order to limit the present invention, within the spirit and principles in the present invention not all, any modification of doing, is equal to replacement, improvement etc., all should be included within protection scope of the present invention.
