Automatic water pump controller draws water

Technical Field

The utility model relates to a water pump control technical field specifically indicates an automatic pump control ware that draws water.

Background

Water pumps are machines that deliver or pressurize a liquid. It transfers the mechanical energy of prime mover or other external energy to liquid to increase the energy of liquid, and is mainly used to transfer liquid including water, oil, acid-base liquid, emulsion, suspoemulsion and liquid metal. Liquids, gas mixtures, and liquids containing suspended solids may also be transported. The technical parameters of the water pump performance include flow, suction lift, shaft power, water power, efficiency and the like; the pump can be divided into a volume water pump, a vane pump and the like according to different working principles. The displacement pump transfers energy by utilizing the change of the volume of a working chamber; vane pumps transfer energy by the interaction of rotating vanes with water and are available in the types of centrifugal pumps, axial flow pumps, mixed flow pumps, and the like. The working principle of the axial flow pump is different from that of the centrifugal pump, and the axial flow pump mainly lifts water by utilizing the thrust generated by the high-speed rotation of the impeller. When the axial flow pump blade rotates, the lift force generated to the water can push the water from the lower part to the upper part. The vanes of an axial flow pump are typically submerged in a pool of water to be pumped. As the impeller rotates at high speed, under the action of the lift force generated by the blades, the water is continuously pushed upwards, so that the water flows out along the water outlet pipe. The impeller rotates continuously, and water is also continuously pumped to a high place. General features of axial flow pumps: (1) the flowing direction of water in the axial flow pump is along the axial suction and axial outflow of the impeller, so the axial flow pump is called; (2) the lift is low (1-13 m), the flow is large, the benefit is high, and the method is suitable for drainage and irrigation in plains, lake areas and river areas;

(3) the water is not needed to be filled before starting, and the operation is simple. The working principle of the mixed flow pump is as follows: because the impeller shape of the mixed flow pump is between the centrifugal pump impeller and the axial flow pump impeller, the working principle of the mixed flow pump is centrifugal force and lift force, and water flows out of the impeller at a certain angle with the shaft by the combined action of the centrifugal force and the lift force, and is extracted to a high position through the volute chamber and the pipeline. The general characteristics of mixed flow pumps: (1) compared with a centrifugal pump, the mixed-flow pump has lower lift and larger flow, and compared with an axial-flow pump, the mixed-flow pump has higher lift and lower flow. Is suitable for drainage and irrigation in plain and lake areas. (2) The water is sucked and discharged along the flowing direction of the mixed flow pump and at a certain angle with the impeller shaft, so the pump is also called as an oblique flow pump. Centrifugal pump models, variety specifications and variants thereof are the most common among agricultural pumps. The centrifugal pump comprises a single-stage single-suction centrifugal pump, a single-stage double-suction centrifugal pump, a multi-stage centrifugal pump, a self-suction centrifugal pump, a motor pump, a diesel engine pump and the like according to the mode of water flowing into the impeller, the number of the impellers, whether the pump body can self-suck, the power size and the power variety of the matching pump and the like. Single-stage single-suction centrifugal pump: the old pump models are BA and B type single-stage single-suction centrifugal pumps, in the 80 s, China carries out updating and developing work on centrifugal pump products according to international standards and actual conditions of drainage and irrigation machinery, and produces IB type and IQ type single-stage centrifugal pump series products, which are listed as national professional standards and industrial standards. The single-stage single-suction centrifugal pump is called as a single-stage single-suction centrifugal pump, water enters an impeller from one axial side, and only one impeller is arranged. Its advantages are high lift, low flow rate, simple structure and convenient application. The IQ type single-stage single-suction centrifugal pump (also called light small centrifugal pump) is designed aiming at the national situation and meeting the requirements of simple structure, light weight, low price, good performance and convenient matching proposed by users, and the IQ type single-stage single-suction centrifugal pump has 84 products in total, and is divided into 3 derived series and 413 specification models. (1) Performance range: the pump has the caliber of 50-200 mm, the flow rate of 12.5-400 cubic meters per hour, the lift of 8-125 meters, and the matched power is direct connection of a diesel engine and belt transmission, and direct connection of a motor, the power of 1.1-110 kilowatts, and the rotating speed of 1450-2900 revolutions per minute. (2) The structure type light small centrifugal pump is an axial suction single-stage single-suction suspension centrifugal pump, the back of the pump body is opened, the outlet is positioned at the center and upwards, the back cover is of a press-embedding type, the bearing body is directly connected with the pump body, the pump foot is positioned below the pump body, the bearing is lubricated by grease, and the shaft seal is divided into three types of soft packing, mechanical seal and rubber oil seal. The impeller is closed, and the transmission is divided into a coupling transmission and a belt transmission. The pump impeller turns: when viewed from the direction of the inlet of the pump, the impeller turns clockwise, and when the pump is in direct connection transmission with the diesel engine, the impeller turns anticlockwise. The pump outlet can be equipped with a manual pump, and the bottom valve can be removed, so that the hydraulic loss is reduced, and the pump can be self-sucked. The single-stage double-suction centrifugal pump is a single-stage double-suction centrifugal pump which feeds water from two sides of an impeller, and is also called a horizontal split centrifugal pump because a pump cover and a pump body are assembled by adopting horizontal joints. Compared with a single-stage single-suction centrifugal pump, the centrifugal pump has the advantages of high efficiency, large flow and higher lift. But the volume is large and heavy, and the device is generally used for fixing operation. The method is suitable for irrigation areas with medium areas in hills and plateaus, and is also suitable for water supply and drainage in factories, mines, cities and the like. The single-stage double-suction centrifugal pump has S type, Sh type, SA type and SLA type, and the S type and the Sh type are different in that the S type pump rotates clockwise and the Sh type pump rotates anticlockwise when viewed from the driving end. The SLA type is a vertical single-stage double-suction centrifugal pump. The performance range of the S-shaped pump is 160-18000 cubic meters per hour, the lift is 12-125 meters, the diameter of the water inlet is 150-1400 millimeters, and the rotating speed is 2950, 1450, 970, 730, 585, 485 and 360 revolutions per minute. (1) D type pump performance range flow 6.3 ~ 720 cubic meter/hour, the lift 16 ~ 600 meters, the bore of intaking: 50. 75 mm, 100 mm, 125 mm, 150 mm and 200 mm, wherein the pump type of 50 mm to 125 mm has a high rotating speed of 2950 rpm, and the pump type of 150 mm to 200 mm has a rotating speed of 1480 rpm. (2) The D-type multistage centrifugal pump is of a horizontal multistage (2-12 stages), the impeller is of a single suction type, and the pump body is of a sectional type. When the first-stage impeller is double-suction, it is indicated by DS, and when two rotation speeds are simultaneously specified, the low speed is indicated by DA, and the multi-stage centrifugal pump for boiler water supply is indicated by DG. The self-priming pump is a single-stage single-suction centrifugal pump which generates self-priming action by means of the special structure of the pump, and is called a self-priming centrifugal pump. Compared with the common centrifugal pump, the pump body structure has the following significant differences: firstly, the position of the inlet of the pump is increased, and sometimes a suction valve is arranged; secondly, a gas-water separation chamber is arranged at the water outlet side. The self-priming pump is characterized by that a self-priming device is added in the pump, such as vortex pump, water ring vacuum pump, jet pump and manual pump, etc. Compared with the common centrifugal pump, the self-priming pump has compact structure and simple operation, not only saves the trouble of filling a large amount of water before starting, but also saves the low valve of the water inlet pipe, reduces the water inlet resistance and increases the water yield of the pump, but has 3 to 5 percent lower efficiency compared with the common centrifugal pump with the same specification. The self-priming pump is mostly applied to light and small sprinkler irrigation units and pipeline sprinkler irrigation units. It has realized the major breakthrough in world submerged motor pump field that magnetic suspension submerged motor pump has effectively solved all sorts of drawbacks of traditional submerged motor pump: such as low conversion efficiency, high power consumption, limited lift, easy damage of the bearing, frequent maintenance and the like.
