Abstract
The utility model relates to a water pump safety protection sensing device. In the device, a spring, a low temperature sensor and a heat preservation ring are arranged in the fixing slot hole which is predetermined at the position of the pumping-out vane near to a water pump. The utility model has the advantages of sensitive protection and sense, waterproofness, heat preservation, good insulating property, simple structure and convenient direct mount.
Description
The utility model relates to a kind of water pump safety protection detective device.
Thereby the water pump Safeguard is a kind of at present is to carry out temperature detection by the coil that is arranged on motor inside to reach temperature control.But this sensing mode easily causes the water pump overburden, makes water pump produce the heat expansion friction, even produces to be locked and phenomenon such as block.Another kind is that feed water pump installs hydraulic press additional, utilizes water to flow and water pressure is come enable switch power supply control motor running.But when water level be lower than water pump drain opening or because of standing retaining tower anhydrous at that time, use and open water tap (promptly discharging water) this moment, it is power-on, motor drives pump operation, surplus water in the water pipe is discharged, so far hydraulic pressure switch is ineffective, and electric motor still keeps running can not stop action because of cutting out water tap.Produce water pump idle running nothing thus and pump up water, make the water pump metal body lead warm rising, the friction loss of the precision of pumping up water in water pump geometric distortion causes stuck at last.And outer electronic motor overloads because of the horsepower sudden change, and current break increases, and the motor coil failure of insulation also causes electric wire to cock off easily.
The purpose of this utility model will provide a kind of being directly installed on the water pump exactly, has water pump safety protection detective device simple in structure, that detecting is sensitive, cost is low.
This device is fastened on Zhou Shangduan centre in the helmet for side face has the helmet of the semicircle tubular of through hole with spring one end; The spring the other end is connected on the low temperature sensor; This low temperature sensor ear end face is U font contact plate, and the contact plate two-terminal is used to connect power line; This low temperature sensor front-end face is cylindric, embedded insulating ring; Again above-mentioned member directly is installed in the default fixedly slotted eye in position of water pump near the blade that pumps up water.
Distinguishing feature of the present utility model is:
1, provide factors such as a kind of not reason hydraulic pressure deficiency, subregion is cut off the water or cut off the water unusually and influence pump working, and avoid motor to burn out, electric wire cocks off etc. dangerous and waste electric power situation takes place;
2, adopting the low temperature sensor, is the temperature actuating range with 40 to 45 degree, and sensing is more sensitive;
3, with the utility model after the dioxygen resin injection combination, each assembly is combined closely more, and have effects such as waterproof, insulation and insulation;
4, simple in structure, mounting point and institute application space are little, are convenient to install and use, and cost is lower.
Description of drawings

Fig. 2 is the utility model STRUCTURE DECOMPOSITION figure
Below in conjunction with accompanying drawing the utility model is described in further detail
This device has the helmet (1) of the semicircle tubular of through hole (11) by side face, and the Zhou Shangduan centre is provided with spring (2) and bears portion (12) in helmet (1); Spring (2) one ends are fastened in the portion of bearing (12), on another termination low temperature sensor (5); This low temperature sensor (5) ear end face is U font contact plate (51), and contact plate (51) two-terminal (58) is used to connect the terminal (71) of power line (7); Low temperature sensor (5) front-end face (52) is cylindric, embedded insulating ring (6).
Helmet (1) directly is installed in the fixedly slotted eye (82) of water pump (8) near blade (81) position of pumping up water with low temperature sensor (5).Being convenient to general electric water pump processing factory directly adopts this device to carry out supporting use.
When assembling, earlier power line (9) is passed the through hole (11) of helmet (1), and terminal (71) connects the terminal (58) that the two ends of the U font contact plate (51) of low temperature sensor (5) erect respectively, put into electric water pump (8) together with spring (2) then and go up default fixedly slotted eye (82) near the blade (81) that pumps up water, again with helmet (1) and after fixedly adhere with instant adhesive in the peripheral clearance position of slotted eye (82) top, can insert the dioxygen resin by the through hole (11) of helmet (1), thereby above-mentioned member is firmly fitted together.
