Technical field
The present invention relates to tap water feedwater field, relate in particular to a kind of automatic vacuum detection system of water feeding pump.
Background technique
At present, the waterworks clear water reserviors all are built in below ground, and the conveying pump in most conveying pumps room all adopts liquid following formula conveying pump, and the prerequisite that liquid following formula conveying pump starts is that conveying pump and water inlet pipe thereof need be full of water (no air).Please refer to shown in Figure 1, this conveying pump 1 need be by operator's manual unlocking vacuum valve 4 before startup, open vacuum pump 2, conveying pump 1 and water inlet pipe 3 thereof are vacuumized, and the water that will be lower than the conveying pump 1 inlet water surface is introduced in the conveying pump 1, and sees that by the site operation personnel (this moment, conveying pump 1 and water inlet pipe 3 thereof all were full of water after the waste pipe 6 of vacuum pump 2 was emitted water, vacuum forms), manually boot conveying pump 1 just now, stop vacuum pump 2 again, close vacuum valve 4.
This scheme needs cumbersome artificial on-site manual operation, and promptly need the Field Force to witness and could determine that vacuum forms after waste pipe 6 is emitted water, not only waste of manpower, and also whole workflow can't realize automated operation.
Summary of the invention
The technical problem that the embodiment of the invention will solve is, overcome the deficiency that above-mentioned prior art exists, a kind of automatic vacuum detection system of water feeding pump is provided, cumbersome operation is manually become automatic control operation, thereby realize conveying pump room unmanned, automatically operation.
For solving the problems of the technologies described above, the embodiment of the invention provides a kind of automatic vacuum detection system of water feeding pump, comprising:
Diversion success detection device is used for detecting the diversion situation of conveying pump when the vacuum pump startup vacuumizes conveying pump, and exports diversion success testing signal; And
Automatic control system left/stops by water pump, is used for opening conveying pump and closing vacuum pump according to described diversion success testing signal.
The embodiment of the invention has following useful effect: by diversion success detection device is set, using vacuum pump that it is vacuumized before conveying pump starts realizes detecting automatically, and open/stop at conveying pump and finish conveying pump under the automatic controlling system and start or close down, remove on-the-spot manual operation from, realized the unmanned of pump house.And system's investment seldom, and principle is simple and clear, and stable and reliable operation has good using value and social benefit.

Embodiment
Below in conjunction with accompanying drawing the embodiment of the invention is described in detail.
Please refer to shown in Figure 2ly, embodiment of the invention automatic vacuum detection system of water feeding pump comprises that mainly water pump leaves/stop automatic control system and diversion success detection device.
Please be simultaneously in conjunction with shown in Figure 3, diversion success detection device is set in place in the draining poor 9 of waste pipe 6 (diameter 50mm) end in vacuum pump 2, can receive the water of waste pipe 6 dischargings.Draining poor 9 is of a size of long 400mm, wide 400mm, high 550mm.Diversion success detection device comprises collecting annulus 10 and water level detection switch 11, diversion success, water level detection switch 11 closures; After collecting annulus 10 discharged water, water level detection switch 11 disconnected and resets, so that next vacuum pump 2 becomes the detection of function signal when starting to diversion.Collecting annulus 10 is of a size of long 200mm, wide 400mm, high 300mm.The discharge orifice 13 (diameter 5mm) by collecting annulus 10 bottoms of automatically reseting discharges water automatically and finishes.The water displacement of vacuum pump 2 is far longer than the water displacement of aperture 13.Vacuum pump 2 is opened, and after the diversion success, collecting annulus 10 is no more than 4 seconds from the time that the full water that begins to intake overflows; Vacuum pump 2 stops, and collecting annulus 10 is discharged into the used time of slack tank by full water and is no more than 15 seconds (promptly automatically reseting the time).Vacuum system detects and satisfies fully resetting time the requirement of production.
For guaranteeing that vacuum forms really, vacuum checking device 7 also is provided in the embodiment of the invention, it is mounted in the electric contact vacuum gauge on vacuum pump 2 intake pipes 5, be used for the vacuum formation situation of conveying pump and water inlet pipe thereof is detected, and automatic control system is opened/stopped to output Vacuum testing signal to described water pump.Vacuum forms, and then (vacuum formation signal is sent to water pump and opens/stop automatic control system the electric contact closure; Vacuum does not form, and then electric contact disconnects (cut-off signal is sent to water pump and opens/stop automatic control system).
Please more simultaneously with reference to shown in Figure 4, water pump leaves/stops automatic control system and electrically connects with described diversion success detection device, conveying pump and vacuum pump respectively, be used to control the unlatching of conveying pump 1 and vacuum pump 2 and close down, can become function signal and vacuum to form signal according to diversion, automatically open conveying pump 1, close vacuum pump 2, close vacuum solenoid 8.Automatic control process be by programmable controller (PLC) water pump operation system, vacuum system, vacuum are formed detect and diversion success detection system chain, automatically move with the safety that guarantees system, this control system adopts the control principle of manual intelligent, size according to water factory's water consumption, by PLC automatic control system output control corresponding rule, determine the platform number of conveying pump working time and operation, thereby realize the unmanned in conveying pump room.
Please again in conjunction with Fig. 5, shown in Figure 6, when needs were opened conveying pump 1, water pump left/stops automatic control system and starts vacuum pump 2 automatically, opens 8 pairs of pipelines of vacuum solenoid and vacuumizes according to the PRODUCTION STATUS of water factory.Water in the water intake well enters conveying pump 1, is discharged in the collecting annulus 10 of diversion success detection device by waste pipe 6 via vacuum pump 2 again.When the water level in the collecting annulus 10 reached predetermined value, water level detection switch 11 closures became function signal to be transferred to automatic control system diversion.Water pump leaves/stops automatic control system and becomes function signal and vacuum to form signal according to the diversion that receives, and opens conveying pump 1 automatically, stops vacuum pump 2, closes vacuum solenoid 8.After this waste pipe 6 no longer includes water, and the water in the collecting annulus 10 is discharged in the rhone 9 by discharge orifice 13, and finally discharge by gutter 12, so the water level of collecting annulus 10 reduces gradually, make water level detection switch 11 disconnect and reset, so that next vacuum pump 2 becomes the detection of function signal when starting to diversion.Manual vacuum valve 4 as the replenishing of vacuum solenoid 8, is enabled manual vacuum valve 4 if vacuum solenoid 8 breaks down in the present embodiment.
The embodiment of the invention is by being provided with diversion success detection device, using vacuum pump that it is vacuumized before conveying pump starts realizes detecting automatically, and open/stop at conveying pump and finish conveying pump under the automatic controlling system and start or close down, removed on-the-spot manual operation from, realize the unmanned of pump house.And system's investment seldom, and principle is simple and clear, and stable and reliable operation has good using value and social benefit.
