Description
Technical field
The utility model relates to a kind of water pump protector, particularly a kind ofly prevents water pump water supply water pipe cutout and damages water pump or burn the multi-function protector of motor.
Background technology
The water condition that is absolutely necessary in daily life, this just requires the water pump operation that supplies water normal, but tend to produce the water pump irregular working and motor also continues situation about moving, cause that water pump damages, burn-down of electric motor after again, principal element has: the one, and water pump vane or main shaft are stuck; The 2nd, water pump lack of water or dehydration idle running; The 3rd, water pump or pipeline freeze, block; The 4th, pump head does not reach predetermined height; The 5th, air can not draw water too much in the pipeline; The 6th, the Water intake for water tower mouth is equipped with ball-cock assembly, and control circuit is malfunctioning; The 7th, three phase electric machine phase-deficient operation water pump can not draw water.Normally move in order to ensure water pump, the past is adopted different solutions often at above-mentioned different problem, like this, not only can raise the cost greatly, but also can increase the workload and the difficulty of installation, maintenance, can increase other fault again.
Summary of the invention
For overcoming the disadvantage of above-mentioned existence, problem to be solved in the utility model provides a kind of simple and compact for structure, versatility and good reliability and can guarantee the water pump multi-function protector of the normal operation of water pump.The technical scheme that its technical problem that solves the utility model adopts comprises controller, valve body, valve gap, controller is fixed on the valve gap, valve gap is fixed by sealing ring and valve body, described valve gap is provided with slide rail, valve body is provided with the boss with the corresponding outside protrusion of slide rail length, is provided with and the slide rail piston that is complementary at the inner chamber of valve body boss, and the outlet side of piston is provided with push rod, back-moving spring is housed on the push rod, and the other end of push rod flexibly connects with the tip-lever support that is arranged on valve outlet; Be fixed with magnet on the piston corresponding with valve gap, controller is provided with the magnetic switch by magnet control.
The piston corresponding with boss is provided with pod apertures.
Described controller comprises housing, control circuit and indicating circuit, control circuit is made up of push-button switch, delay switch, magnetic switch, relay and socket, and the out-put supply display circuit that input power indicating circuit that indicating circuit is composed in series by resistance that is connected input and indicator light and the resistance that is connected output and indicator light are composed in series is formed.
After adopting said structure, the power supply of pump motor is connected with the socket of controller, when the water pipe normal water supply, hydraulic pressure overcomes the elastic force of back-moving spring, and piston is in the Way out of boss, and this moment, magnetic switch was in closure state, relay work, socket is powered to pump motor; When undesired water supply occurring, water pipe produces when stopping or cutting off the water supply, under the effect of back-moving spring, the importer that piston is got back to boss to, at this moment, magnet on the piston is corresponding with the magnetic switch of controller, and make magnetic switch be in off-state, and the relay outage, the socket non-transformer is supplied with pump motor, water pump quits work, and produces the problem that the water pipe cutout causes the damage water pump or burns motor thereby solved various factors preferably; Have simple and reasonable, versatility and good reliability, convenient, the low cost and other advantages of installation and maintenance.

Embodiment
Illustrated in figures 1 and 2, specific embodiments for a kind of water pump multi-function protector of the utility model, it comprises controller 1, valve body 4, valve gap 2, controller 1 is fixed on the valve gap 2, valve gap 2 is fixing with valve body 4 by sealing ring 3, described valve gap 2 is provided with slide rail 6, valve body 4 is provided with the boss 12 with the corresponding outside protrusion of slide rail 6 length, be provided with and slide rail 6 piston 7 that is complementary at the inner chamber of valve body boss 12, the outlet side of piston 7 is provided with push rod 9, back-moving spring 10 is housed on the push rod 9, and the other end of push rod 9 flexibly connects with the tip-lever support 11 that is arranged on valve outlet; Be fixed with magnet 5 on the piston 7 corresponding with valve gap 2, controller 1 is provided with the magnetic switch K2 by magnet 5 controls; The piston 7 corresponding with boss 12 is provided with pod apertures 8.Described controller 1 comprises housing, control circuit and indicating circuit, control circuit is made up of push-button switch AN, delay switch K1, magnetic switch K2, relay ZJ and socket CZ, and the out-put supply display circuit that input power indicating circuit that indicating circuit is composed in series by resistance R 1 that is connected input and indicator light D1 and the resistance R 2 that is connected output and indicator light D2 are composed in series is formed.
Before the utility model uses, earlier valve body and water pipe are joined, the power supply of pump motor is connected with the socket of controller, and magnetic switch K2 is in off-state.During use, start button switch AN, delay switch K1 get and work simultaneously after electric and delay cut-off, relay ZJ work, socket CZ powers to pump motor, behind the pump working, hydraulic pressure overcomes the elastic force of back-moving spring 10, piston is pushed to the Way out of boss, because the magnet 5 on the piston 7 breaks away from the correspondence position with magnetic switch K2, magnetic switch K2 is closed and to relay ZJ power supply before delay switch K1 outage, maintenance pump motor normal power supply, water pump normal water supply.When undesired water supply occurring, water pipe produces when stopping or cutting off the water supply, under the effect of back-moving spring 10, the importer that piston is got back to boss 12 to, at this moment, magnet 5 on the piston 7 is corresponding with the magnetic switch K2 position of controller, make magnetic switch K2 be in off-state, relay ZJ outage, socket CZ stops to power to water supply pump motor, water pump quits work, and produces the problem that the water pipe cutout causes the damage water pump or burns motor thereby solved various factors preferably.
