Description
Technical field
The invention belongs to pump technology field, relate in particular to a kind of energy-conserving intelligent water that adopts VFCPump.
Background technology
Water is the root of human survival, and water is agriculture lifeblood. China be people many, less, lack of water,The country of frequent natural calamity. Agricultural irrigation water accounts for the more than 80% of national water total amount, and China WaterTotal resources accounts for 7% of global total amount, and water resource is 1/4th of world's per capita share per capita, quiltThe United Nations classifies one of 13 lack of water countries as. China with 7% water in the world maintain 22% population production andLife. In 517 cities, the whole nation, have more than 300 urban water shortage, China is again a large agricultural country, agricultureIndustry is water rich and influential family, annual agricultural irrigation water amount approximately 3500 billion cubic meters, and due to water resource deficiency, IThe annual area suffered from drought of state's agricultural reaches hundred million mu of 2-3, and grain reduces approximately 2.5 hundred million kilograms, and industrial output value reduces 1200Hundred million yuan. Along with China's economy develops rapidly, water resources problems is day by day serious.
Jet pump is to utilize the transformation of fluid flow energy to reach the object of conveying, utilizes it can conveying liquidBody, also can carry gas. According to working fluid used, be generally divided into steam jet pump and water stream injection pumpTwo classes, jet pump simple structure, easy to use. Water stream injection pump is divided into again Ordinary Centrifugal Pumps and Self-sucking sprayPenetrate pump, Ordinary Centrifugal Pumps, if suck liquid level under impeller, should pour water when startup in advance, very inconvenient.For water in pump, suction line import need to fill bottom valve, and when pump work, bottom valve causes very large waterpowerLoss. Self-priming injection pump does not need to pour water exactly before startup, through short-time running, by pump itselfEffect, can drink up water, drops into and normally works.
Water pump of the prior art only has a kind of operating current, and lift all sets in the time dispatching from the factory,In practical application, cannot change, also just cannot need to regulate lift according to the actual water level depth, workIn journey, be a kind of waste for the energy, cannot reach energy-conservation object.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of and forms simply, the employing that operating cost is lowThe energy-conserving intelligent water pump of VFC.
Technical problem to be solved by this invention realizes by the following technical solutions:
Adopt an energy-conserving intelligent water pump for VFC, the motor that comprises the pump housing and be connected with the pump housing,One casing is installed on the shell of the described pump housing, in described casing, is provided with a frequency converter, described frequency converterBe connected with motor, change the operating current of motor by frequency converter, control the rotating speed of motor, describedThe water outlet of the pump housing is provided with a flow velocity probe, and described flow velocity probe is connected with IC chip, described IC coreSheet is arranged in casing, and described IC chip is connected with frequency converter, for controlling frequency converter, when water levelWhen shallow, flow velocity probe detects water velocity hour, this flow velocity signal is transferred to IC chip, through ICAfter chip analysis, give frequency converter working signal, the electric current of Frequency Converter Control motor, makes motorOperating current diminishes, and rotating speed reduces, thereby adjusts the water yield according to water level situation, ensures normal water outlet,Do not waste energy because lift is too high.
Described flow velocity probe is installed along the diametric(al) of pump housing delivery port, and certainty of measurement is high, easy for installation.
Described casing is arranged on the top, rear portion of motor, regulates the counterweight of motor, makes in the course of the workMore stable.
On described IC chip, be also connected with an alarm, in the time that motor is normally worked, flow velocity probe detectsWhen non-water flow, flow velocity probe is to signal of IC chip, and IC chip is reported to the police by alarm, remindsStaff switches off the pump.
The invention has the beneficial effects as follows: structural design advantages of simple of the present invention, adopt frequency conversion control technique,Make the water pump can be according to the actual water level depth, self-regulation motor size of current, controls pump speed then,Ensure normal water outlet, do not waste energy because lift is too high.
Brief description of the drawings
Fig. 1 is outline drawing of the present invention;
Fig. 2 is principle of the invention block diagram.
Detailed description of the invention:
For technological means, creation characteristic that the present invention is realized, reach object and effect is easy to understandSeparate, below in conjunction with concrete diagram, further set forth the present invention.
As shown in Figure 1 and Figure 2, a kind of energy-conserving intelligent water pump that adopts VFC, comprise the pump housing 1 and withThe motor 2 that the pump housing 1 connects, is provided with a casing 3 on the shell of the pump housing 1, be provided with a frequency converter in casing 34, frequency converter 4 is connected with motor 2, changes the operating current of motor 2 by frequency converter 4, controls motor 2Rotating speed, at the water outlet of the pump housing 1, a flow velocity probe 5 is installed, flow velocity probe 5 is connected with IC chip 6,IC chip 6 is arranged in casing 3, and IC chip 6 is connected with frequency converter 4, for controlling frequency converter 4, works as waterPosition is when more shallow, and flow velocity probe 5 detects water velocity hour, and this flow velocity signal is transferred to IC chip 6,After IC chip 6 is analyzed, give 4 one working signals of frequency converter, frequency converter 4 is controlled the electric current of motor 2,The operating current of motor 2 is diminished, and rotating speed reduces, thereby adjusts the water yield according to water level situation, is just ensureingNormal water outlet, does not waste energy because lift is too high. Flow velocity probe 5 is installed along the diametric(al) of the pump housing 1 delivery port,Certainty of measurement is high, easy for installation. Casing 3 is arranged on the top, rear portion of motor 2, regulates the counterweight of motor 2,Make more to stablize in the course of the work. On IC chip 6, be also connected with an alarm 7, when the normal work of motor 2While work, when flow velocity probe 5 detects non-water flow, flow velocity probe 5 is given 6 one signals of IC chip, IC chip 6Report to the police by alarm 7, remind staff to switch off the pump.
More than show and described general principle of the present invention and principal character and advantage of the present invention. One's own professionThe technical staff of industry should understand, and the present invention is not restricted to the described embodiments, above-described embodiment and explanationThat in book, describes just illustrates principle of the present invention, without departing from the spirit and scope of the present invention,The present invention also has various changes and modifications, and these changes and improvements all fall into claimed model of the present inventionIn enclosing.
