The accompanying drawing explanation
Fig. 1 is structure principle chart of the present utility model.
Embodiment
From structure principle chart of the present utility model shown in Fig. 1, can find out, the utility model comprises mortor operated valve A5, mortor operated valve B8, flowmeter 1, PLC controller, water pump 4, pump motor 7 and pumping system, and each water pump 4 is connected with pump motor 7.Flowmeter 1 and mortor operated valve A5 are housed on the rising pipe 2 of each water pump 4, and the rising pipe 2 of two parallel connections is connected with water pump 4 outlets, and mortor operated valve B8 is equipped with in water pump 4 outlets.Water pump 4 is connected with the water injecting pipeline 3 that fluidic system 6 is housed, and level sensor 9, vacuum transducer are housed in pumping system, and the PLC controller is connected with each mortor operated valve, flowmeter 1, pumping system.Level sensor 9 adopts ultrasonic water-level gauge continuous detecting water bunker level, and ultrasonic water-level gauge output 4～20mA signal send the PLC controller, and the PLC controller is differentiated through computing, automatically the start-stop water pump.When normal water level, each water pump energy automatic alternate work, when flood stage, automatically drop into the water pump operation of necessary amount, and automatically control the mortor operated valve on respective line.
The utility model can be summarized as following six links: automatic water filling link, gate valve manipulation link, water level automatic monitoring link, parameter pass the automatic control link of showing link, error protection link and motor.
1, automatic water filling link.Water pump is only in the situation that, during its impeller is submerged in water fully, pump body just can cause necessary degree of vacuum to realize normal draining.If degree of vacuum is inadequate, in pump, there is air to exist, will not cause the faults such as water and rotatable parts burn out.Therefore, the water filling before starting is one of important operation project of pump working, by the water injecting pipeline 3 that fluidic system 6 is housed, carries out water filling.By highi degree of accuracy vacuum transducer monitoring vacuum, electric current, flow are as the standby of monitoring vacuum.
2, gate valve is handled link.Be full of water in the pump housing after, take and start and stop the 1# pump as example, its process is as follows: during startup, first start the 1# motor, then open corresponding mortor operated valve (with " wheel changes jobs " principle, according to the pipeline used last time, this changes pipeline another time), while stopping, first closing mortor operated valve, finally stop the 1# motor.
3, water level automatic monitoring link.The task of water level automatic monitoring link is according to the automatic accurate pump order of sending out, cut off the water of the height of water level.The reliability of level sensor 9 and accuracy directly affect the functional reliability of whole control system.Level sensor 9 is selected ultrasonic liquid level sensor for this reason, it have highi degree of accuracy, contactless, on-mechanical type, easy to maintenance, install easily, demarcate many advantages such as simple.Be provided with water level I, water level II, water level III, water level IV, when water level reaches the water level II, if, in low accounting regime, can start immediately, if in high charging section, postpone starting.When water level continues to rise to the water level III, no matter electrical network how, must start water pump.When if water level continues to rise to the water level IV, show that the water displacement of a water pump has been not enough to get rid of the mine water outlet, must start second water pump, two water pump drainings simultaneously, get rid of the mine water outlet with the maximum drainage capacity of mine.No matter drop into several pumps, water level must drop to the water level I can termination of pumping.Above-mentioned water level I to water level IV is sent analogue signal into PLC by ultrasonic liquid level sensor, by PLC, by software, is demarcated.Time-shared charge is also demarcated by software by PLC.
4, parameter passes and shows link.Can simulate the various working staties that show water bunker level, pump capacity, water-aspirator pressure and motor, mortor operated valve on the imitation screen of operating table.All detected parameters and working state all can send ground-based computer to by transmission network by down-hole PLC, by Computer Analysis, processed, on display device, simulation shows, and make curve, form, be beneficial to the floor control personnel and make accurate judgment, to the down-hole programmable controller, send control command.
5, error protection link.The pump motor capacity is large, and power consumption is high, belongs to a stage load.Therefore, higher to Security, the reliability requirement of drainage equipment automatic control system.Can realize traffic protection, after starting mode of pump or normally in service, as flow does not reach normal value, by flow rate protective device, this TV station water pump be stopped, transfer to and start another water pump; Realize motor fault protection, PLC monitors the faults such as pump motor is under-voltage, overcurrent, short circuit, is provided by the comprehensive protection device of high-tension switch cabinet, and participates in controlling; Realize the electric gate valve fault.
6, the automatic control link of motor.This link is the key link of drainage equipment integrated automation control system, and above link all will coordinate with this link, according to the automatic start-stop water pump of water level situation.In order to prevent need not making for a long time motor make moist or have other fault undiscovered because of stand by pump, when urgency need to drop into and can not drop into so that affect mine safety, this link is controlled by " rotation duty ", to reach, there is fault early to find, early process, in order to avoid affect the purpose of mine safety.System according to the opening times of water pump automatically rotation in certain sequence open water pump, when certain or under it when failsafe valve or maintenance, this pump exits rotation, all the other each pumps are still by the operation of rotation duty.
