Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

In the description of the present invention, it is to be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and to simplify the description, but do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore should not be construed as limiting the present invention.

As shown in fig. 1, the utility model discloses a sump pit water pump supplies drainage control system, including liquid level relay, two water pumps 3 that link to each other with liquid level relay, a water pump work, a water pump is reserve, two water pumps 3 dispose the water pump respectively and start water filling valve 5, all install bottom valve 1, water intaking valve 2 and vacuum gauge 4 on every water pump 3's the inlet tube, install manometer 6 and flow control valve 8 on every water pump 3's the outlet pipe road, work flow is measured by glass rotameter 7, the hole water source is watered to the water pump draws outdoor entering water pump water filling house steward, liquid level relay adopts JYB714 type liquid level relay.

In the primary wiring of the water pump motor, a power meter, an ammeter, a voltmeter and a power factor appearance are adopted to measure the working state of the water pump when the motor works. The line protection adopts a small circuit breaker QF, a fuse FU, a thermal relay FR and an alternating current contactor KM to control and protect a working motor M1 and a standby motor M2 of the water pump. The working water pump 1 and the standby water pump 2 can be mutually arranged to switch the working pump and the standby pump. As shown in fig. 2.

The drainage mode action contact and wiring diagram of the liquid level relay is shown in figure 6.

The working principle of the drainage mode is as follows:

(1) When the water level rises to a high level, the

contacts

7, 6 and 5 of the liquid level relay SL1 are simultaneously switched on, and the normally

open contacts

2 and 3 are closed to send a working pump starting command. As the working pump operates and the water level decreases, the

contacts

2, 3 are maintained closed by the contacts 6, 7. When the water level is reduced to a low water level, the connection parts 6 and 7 are disconnected, the

connection parts

2 and 3 are disconnected, and the working pump stops running.

(2) If the water level reaches the high water level, the

contacts

2 and 3 of the SL1 are switched on to enable the water level to rise at all after the working pump is started, when the water level reaches the ultrahigh water level, the

contacts

7, 5 and 6 of the SL2 are switched on simultaneously, and the normally-

open contacts

2 and 3 of the SL2 are closed to send a standby pump starting command. Before the water level is lowered to a low water level, the 6 and 7 switches on and the 2 and 3 switches off, until the water level reaches the low water level, the 6 and 7 switches off, the 2 and 3 switches off, and the working pump and the standby pump stop running at the same time.

The water supply mode connection point action diagram and the connection line of the liquid level relay are shown in figure 7.

Working conditions the working principle of the water supply mode is as follows:

(1) When the water level is reduced to a low water level, the normally closed contact of the liquid level relay SL1 sends a working water pump starting command, the working water pump is switched on to switch 3 and 4 off when the water level is increased to 5, 6 and 7 along with the operation of the working water pump, and the working water pump stops operating.

(2) If the water level drops to the low water level, the SL2 normally-closed

contacts

3 and 4 are switched on to start the backup pump, and when the water level reaches the high water level, the

SL2 contacts

3 and 4 are switched off to stop the backup pump.

The switching of the water supply and drainage modes of the liquid level relay is realized by selecting the water supply mode and the drainage mode through a universal change-over switch SA 3. The specific circuit wiring is shown in fig. 8. The manual and automatic operation of the water pump in the water supply or discharge mode is switched by universal switches SA1 and SA2, respectively, see fig. 4 in particular. The running indication green lamps HG1 and HG2 of the pump 1 and the pump 2 are used for displaying in the running process of the water pump, and the stop state is displayed by the red lamps HR1 and HR 2. The standby status is displayed by yellow lamps HY1 and HY 2. See in particular fig. 3 and 5.

The system can manually control the water supply or the water discharge of the water pump, and can also automatically detect the water level through the liquid level relay to instruct the water supply and the water discharge system controlled by the liquid level relay. The patent can be applied to the control of the water supply system of the water collecting well of the industrial and mining enterprises, and can also be applied to the design of the drainage system of the industrial and mining enterprises. The device uses a water supply or drainage system controlled by a liquid level relay, has simple structure, low cost and convenient maintenance, and is widely applied to water supply and drainage systems of fish ponds, lakes and the like in rural areas and small-sized automatic water supply and drainage control systems of industrial and mining enterprises.
