Energy-saving advanced type impeller suspension type electromagnetic flowmeter for agriculture and forestry irrigation

Abstract

Provided is an energy-saving advanced type impeller suspension type electromagnetic flowmeter for agriculture and forestry irrigation. The energy-saving advanced type impeller suspension type electromagnetic flowmeter for agriculture and forestry irrigation comprises an electromagnetic flowmeter and circuit of a novel energy-saving impeller suspension non-shaft support, and further comprises a novel flow adjustable water dropper, a novel 360-degree shower nozzle, a connector capable of finely adjusting the size and screw pitch of a thread ring, an electromagnetic flowmeter body, and interfaces between an energy-saving type sprinkler timer with multiple interfaces and a water knockout drum, optional collocation is easy, and the components are matched for the water-saving method and used for the garden efficient irrigation energy and water conservation. The advanced type rolling assisting enables one-stage rotation of impellers to be changed into multi-stage rotation between inner pipes of an outer shell, so that the relative linear velocity of every two adjacent rotary pairs is reduced. A rolling body has the magnetism used for magnetic suspension, the magnetic induction impellers are matched, a support, having resistance on fluid flow, of six rods of a conventional center shaft is omitted, the magnetic suspension and advanced type rolling assisting are used, the resistance of the flowmeter to the fluid flow is smaller, less idle work is consumed, friction is smaller, and accuracy is higher.

Description

technical field [0001] The invention relates to a control method of water flow for environmental protection and landscaping, which is an energy-saving advanced impeller suspension type electromagnetic flowmeter for agriculture and forestry irrigation, including a new electromagnetic flowmeter, a circuit and a water-saving method, including a flow rate Adjustable drippers, 360-degree nozzles, fine-tuning joints, sprinkler timers and water distributors, with advanced rolling assistance, make the impeller turn from one-stage rotation to multi-stage rotation, and make the relative linear speed of each adjacent rotating pair Reduced, less friction and more accurate precision.

AI Technical Summary

Problems solved by technology

Existing products vary, and none of them are perfect; there is a certain nozzle (55ac), such as Figure 31 As shown, the water is connected to the nozzle seat (55c) of the certain nozzle (55ac) through the matching components and then sprayed out through the only small square hole provided on the nozzle cap as the water nozzle (55a3c). Its disadvantage is that the range of sprayed water is narrow, and it cannot have a 360-degree all-round irrigation effect.

Another nozzle (55ad) for existing products, such as Figure 32 As shown, the water is connected to the nozzle seat (55c) of the certain nozzle (55ad) through the matching components, and is sprayed out through the large through hole opened on the half side of the nozzle cap as the water nozzle (55a3d) , its shortcoming is that the range of sprayed water is only half, and cannot have a 360-degree all-round irrigation effect

The existing electromagnetic flowmeter is made based on Faraday's principle of electromagnetic induction. When the conductor cuts the magnetic force line in the magnetic field, an induced potential proportional to the liquid flow rate is generated, and is detected by the electrode in contact with the liquid, so that it is converted by the cable. After intelligent processing, the communication and control between the flow data and the computer are realized. The existing electromagnetic flowmeter includes a measuring tube, an inlet flange, an outlet flange, electrodes, an excitation wire, a measuring tube housing, a circuit board and The display device, in which the measuring tube, the inlet flange, the outlet flange and the measuring tube housing are all made of metal materials, the disadvantages of using metal materials are: the weight of the entire flowmeter is relatively large, and it is inconvenient to install and maintain. The work efficiency is affected by the cooperation of people; and the cost of metal materials is high, which makes the price of the finished flowmeter more expensive; therefore, it is necessary to improve the existing electromagnetic flowmeter
