Abstract
The utility model discloses one and prevent water pump evacuator, comprise water pump, timer, pressure-detecting device and control gear, described pressure-detecting device is arranged on the water outlet of water pump, and described timer, pressure-detecting device are all connected with control gear with water pump.Originally prevent water pump evacuator from controlling water pump whether stall by detecting the discharge pressure of pump outlet, when water pump discharge pressure at the appointed time in do not reach setting value, water pump will be automatically out of service, effectively prevent the problem affecting water pump working life because water pump dallies for a long time.
Description
Technical field
The utility model relates to a kind of anti-evacuator, and in particular one prevents water pump evacuator.
Background technique
Existing water pump controls generally to control based on normal pumping by water pump.But occur special circumstances as crossed, as water pump is taken out less than water, occur idle running phenomenon, water pump generally can not control to stop, if water pump dallies for a long time will have a strong impact on the working life of water pump automatically.
Therefore, prior art has yet to be improved and developed.
Summary of the invention
The purpose of this utility model is to provide one to prevent water pump evacuator, and being intended to solve water pump idle running can not stall in time, affects the problem in water pump working life.
The technical solution of the utility model is as follows: one prevents water pump evacuator, wherein, comprise water pump, timer, pressure-detecting device and control gear, described pressure-detecting device is arranged on the water outlet of water pump, and described timer, pressure-detecting device are all connected with control gear with water pump.
Described prevents water pump evacuator, and wherein, described pressure-detecting device is pressure switch.
The beneficial effects of the utility model: the utility model prevents water pump evacuator by providing one, originally prevent water pump evacuator from controlling water pump whether stall by detecting the discharge pressure of pump outlet, when water pump discharge pressure at the appointed time in do not reach setting value, water pump will be automatically out of service, effectively prevent the problem affecting water pump working life because water pump dallies for a long time.
Accompanying drawing explanation
Fig. 1 is the structural representation preventing water pump evacuator in the utility model.
Embodiment
For making the purpose of this utility model, technological scheme and advantage clearly, clearly, referring to the accompanying drawing embodiment that develops simultaneously, the utility model is further described.
As shown in Figure 1, be the structural representation preventing water pump evacuator in the utility model.Originally prevent water pump evacuator from comprising water pump 100, timer, pressure-detecting device 200 and control gear, described pressure-detecting device 200 is arranged on the water outlet of water pump 100, described timer, pressure-detecting device 200 are all connected with control gear with water pump 100: when water pump normal pumping, timer is failure to actuate; When idle running appears in water pump, pressure-detecting device 200 is the force information back detected to control gear, and control gear controls timer and starts timing, if the discharge pressure of water pump in set time recovers normal, then water pump maintains action; If the discharge pressure of water pump in set time does not all recover normal, then control gear controls water pump stall, to reach the effect of protection water pump.
Preferably, described pressure-detecting device 200 is pressure switch.
Originally prevent water pump evacuator from controlling water pump whether stall by detecting the discharge pressure of pump outlet, when water pump discharge pressure at the appointed time in do not reach setting value, water pump will be automatically out of service, effectively prevent the problem affecting water pump working life because water pump dallies for a long time.
Should be understood that; application of the present utility model is not limited to above-mentioned citing; for those of ordinary skills, can be improved according to the above description or convert, all these improve and convert the protection domain that all should belong to the utility model claims.
Claims (2)
