Description
Technical Field
The utility model relates to a device for automatically controlling liquid level by pumping water remotely.
Background
Most of industrial water is pumped in nearby rivers, a reservoir is arranged in a factory area and pumped to each workshop by production water, and water pumps are installed in pump rooms beside the rivers. The reservoir is provided with a drop-in liquid level transmitter, and then the liquid level transmitter is connected with a signal line to feed back to the pump frequency converter, and the liquid level control is suitable for short-distance control. The inconvenient wiring of water pump and cistern distance far away can only manual control. According to Chinese patent documents, CN201610516962.1 discloses a wisdom vary voltage water supply control system, including human-computer interface, PLC controller, converter, water pump, teletransmission manometer and flowmeter, the PLC controller is connected human-computer interface, converter, teletransmission manometer and flowmeter respectively, and converter output control water pump, teletransmission manometer and flowmeter are installed to water pump room output, and far-end user and near-end user all are connected to in the water distribution network. The utility model changes the given value of water supply pressure in time according to the water consumption, so that the whole water system can completely meet the use requirement. The liquid level is not automatically controlled by pumping water remotely.

Drawings
FIG. 1 is a schematic diagram of the principles of the present invention;
in the figure: the device comprises a water suction pump at the edge of a river, a water pipe 2, a water pump for production 3, a throwing-in liquid level transmitter 4, a PID regulator 5, an analog quantity wireless transmitter 6, an analog quantity wireless receiver 7 and a frequency converter 8.
Detailed Description
As can be seen from figure 1, the device for automatically controlling the liquid level by remotely pumping water comprises a water pipe 2 connected with a riverside water pump 1, the other end of the water pipe is connected with a reservoir, a production water pump 3 is arranged on one side of the reservoir, the riverside water pump 1 is connected with a frequency converter 8 through a wire, the frequency converter 8 is connected with a wireless receiver 7, the reservoir is provided with a liquid level transmitter 4, and the transmitter is connected with a PID (proportion integration differentiation) regulator 5 through a wire and then is connected with a wireless transmitter 6.
The liquid level transmitter is of a model HALO-FT-WG, the PID regulator is of a model NHR5300, the wireless transmitter is of a model CZ80DTDF, the wireless receiver is of a model CZ80DTDF, and the frequency converter is of a model AC60 Wei frequency converter.
The working principle is as follows: the wireless receiver receives the current signal and transmits the current signal to the frequency converter to control the rotating speed and the flow of the water pump beside the river; when the water level of the water pool is higher than a set value, the output current of the PID intelligent regulator is reduced, the output frequency of the frequency converter is reduced, the rotating speed of the water pump at the river side is reduced, and the flow is reduced; when the pond water level is low, PID regulator output current grow, converter output frequency grow, riverside water pump rotational speed risees, the flow increase, thereby the liquid level of automatic control cistern, signal that intelligence PID regulator fed back according to input liquid level changer, demonstrate the actual water level of cistern, want the water level height of control cistern, just as long as set up the control target value of intelligence PID regulator, the regulator just can pass through analog quantity wireless transmitter and give the converter, thereby reach the effect of stabilizing the cistern liquid level.
