Abstract
The utility model relates to an automatic water supply device for water housings, which is characterized in that a leakage switch and an alternating contactor are in parallel connected with a three-phase switch on two phases or three phases respectively. The utility model has the advantages that manual water supply can be adopted by applying a spare switch when the automotive water supply device does not work in order, or pipes freeze at the temperature below zero DEG C in winter, or water capacity of well is deficient in draught time. Because of the application of the automatic water supply device, possible problems of cutting off of water supply in the conditions can be resolved.
Description
Technical field
The utility model relates to the water tower automatic water-supplying device.
Background technology
Existing water tower automatic water supply device mostly is the float-ball type water supplying apparatus; under normal circumstances can realize automatic water-supply; but; when automatic water supply device breaks down; or winter the subzero pipeline occur when freezing, or when arid during the well water shortage, existing automatic water supply device just can not in time supply water; the problem of cutting off the water appears in regular meeting, fragile pump motor.
Summary of the invention
In order to overcome the problem that above-mentioned automatic water supply device exists, the utility model provides a kind of new water tower automatic water supply device of supplying water of also can guaranteeing under improper situation.
The technical solution that realizes above-mentioned purpose is: the new water tower automatic water-supplying device, comprise pump motor, leakage switch, liquid level relay and A.C. contactor, leakage switch and A.C. contactor are serially connected on the power line of pump motor, it is characterized in that: be parallel with single-phase with leakage switch and A.C. contactor or the three-phase load switch on single-phase or three-phase power line.
The beneficial effects of the utility model are, when automatic water supply device breaks down, or when winter, the subzero pipeline froze, or when arid during the well water shortage, or other reason is can not automatic water-supply the time, at this moment just can enable backup circuit breaker and adopt artificial water application's mode to solve the water difficulty, thereby solve the problem of cutting off the water that the user may occur in these cases.
Of the present utility model being also advantageous in that: the user is safe in utilization.The voltage of three contacts in the water tower is that the 24V direct current does not have any harm to human body; This water supplying apparatus prolongs several times than existing water supplying apparatus application life; Easy break-down is not easy for installation.Use this water supplying apparatus can also prolong the application life of pump motor simultaneously.
Description of drawings
Fig. 1 is a three-phase alternating current automatic water supply device structural representation,
Fig. 2 is a single-phase alternating current automatic water supply device structural representation.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described by embodiment.
Embodiment 1:
This water tower automatic water supply device is the three-phase alternating current automatic water-supplying device, comprises pump motor 1, three-phase leakage switch K1, K2, K3, liquid level relay 2 and A.C. contactor CJ, CJ1, CJ2, CJ3.Wherein the model of liquid level relay 2 is JYB-714 (380V), leakage switch K1, K2, K3 and A.C. contactor CJ1, CJ2, CJ3 are connected on the three-phase power line of pump motor, are parallel with three-phase load K switch 4, K5, K6 with leakage switch and A.C. contactor on three-phase power line.3, Fig. 1 is seen in 4,5 three contacts that are respectively water tower the inside.
Under the normal operating conditions, leakage switch K1, K2, K3 closure, three-phase load K switch 4, K5, K6 disconnect, when water tower level reduces at 4, liquid level relay 2 closures, A.C. contactor CJ1, CJ2, CJ3 closure, pump motor 1 running, water pump begins the work of drawing water.When water level rose at 3, liquid level relay 2 disconnected, and stopped the power supply to A.C. contactor CJ, A.C. contactor CJ1, CJ2, CJ3 open circuit, and water pump stops to supply water.Three-phase load K switch 4, K5, K6 are backup circuit breaker, when automatic water supply device breaks down, temperature is when the subzero pipeline freezes in the winter time, in dry season during the well water water shortage, or other reason can not be used when using automatic water-supply, at this moment leakage switch K1, K2, K3 be can disconnect, three-phase load K switch 4, K5, K6 artificial water application used.
Embodiment 2:
Referring to Fig. 2, this water tower automatic water supply device comprises pump motor 1, single-phase leakage switch K1, K2, liquid level relay 2 and A.C. contactor CJ, CJ1, CJ2 (220V) for exchanging automatic water supply device.Wherein the model of liquid level relay 2 is JYB-714 (220V), leakage switch K1, K2 and A.C. contactor CJ1, CJ2 are connected on the single phase poaer supply line of pump motor 1, are parallel with single-phase load K switch 4, K5 with leakage switch and A.C. contactor on the two-phase power supply line.3,4,5 three contacts that are respectively water tower the inside.
The operating principle of this water supplying apparatus is with embodiment 1.
