Abstract
The utility model discloses a high-pressure terrace pump which comprises a pump shell; a pump shaft is arranged in the pump shell; the top end of the pump shaft is connected with a pulley, and the bottom end of the pump shaft is connected with an impeller; a bearing is arranged at the lower part of the pump shell and is matched and connected with the pump shaft; a water inlet tube and a water outlet tube are arranged below the pump shell; the lower part of the pump shaft extends into the water inlet tube; the water inlet tube and the water outlet tube are in vertical structures; the lower part of the water inlet tube and the bottom of the water outlet tube are communicated through a connecting pipeline; and the connecting pipeline is vertically communicated with the water outlet tube. The high-pressure terrace pump has simple structure, is convenient to operate, has high water pumping efficiency, improves the water yield by more than 30 percents compared with traditional terrace pumps with the same power, has long service life and discharges water stably.
Description
Technical field
The utility model relates to the suction pump field, specifically is that a kind of high pressure is by ridge pump.
Background technique
Existing agricultural high pressure mostly is direct oblique connection by the flooding tube and the water output cylinder of ridge pump, after water is successively by flooding tube, water output cylinder, hydraulic pressure causes the suction sleeve that is connected with water output cylinder to bear very big impact force, cause suction sleeve very easily to be out of shape, reduced its working life, and the impeller that is provided with in the flooding tube is common trilobed wheel, it is very low that the water that will flow through gets rid of on peripheral pump case runner efficient, it is very little to make the pump impeller center form vacuum pressure owing to water is thrown out of, cause by ridge pump go out water unstable, the efficient of drawing water imitates low.
The model utility content
The technical problems to be solved in the utility model provides a kind of high pressure by ridge pump, solve existing by the ridge pump water unstable, the inefficient problem of drawing water.
The technical solution of the utility model is:
High pressure is by ridge pump, comprise pump case (1), be provided with pump shaft (2) in the pump case (1), pump case (1) below is provided with flooding tube (5) and water output cylinder (6), pump shaft (2) bottom is stretched in the flooding tube (5), it is characterized in that: the bottom of described pump shaft is connected with centrifugal impeller (7), and the sidepiece of described flooding tube (5) is communicated with connecting tube (8), and the top of connecting tube (8) is communicated with water output cylinder (6).
Central angle between the adjacent blades of described centrifugal impeller (7) is less than or equal to 45 degree.
The bottom of described flooding tube (5) is communicated with cartridge type filter screen (9).
The axle center of the axle center of described centrifugal impeller (7) and flooding tube (5) is an eccentric structure.
The bottom of pump shaft described in the utility model is connected with centrifugal impeller, because of the central angle between its adjacent blades reduces, guaranteed that the centrifugal force that the centrifugal impeller rotation produces increases, improved the efficient of drawing water by ridge pump, and water outlet is more stable, and by between water output cylinder and flooding tube, being communicated with connecting tube, the sidewall of connecting tube is to entering the certain resistance of water generates in the water output cylinder in advance, weakened the impact force that current produce because of centrifugal impeller, guaranteed that the hydraulic pressure that suction sleeve bore that is connected with water output cylinder weakens, improved the working life of suction sleeve, and water outlet is more stable.
The utility model is simple in structure, and is easy to operate, and the efficient of drawing water height under the same power, is compared the existing ridge pump that leans on, and its water-outlet quantity improves more than 30%, and long service life, stable water outlet.
Description of drawings
Fig. 1 is a plan view of the present utility model.
Fig. 2 is the sectional drawing of A-A among Fig. 1.
Embodiment
See Fig. 1, high pressure is by ridge pump, comprise pump case 1, be provided with pump shaft 2 in the pump case 1, the pump shaft top is connected with belt wheel 3, its bottom is connected with centrifugal impeller 7, be positioned at pump case 1 bottom and be connected with bearing 4 with pump shaft 2, pump case 1 below is provided with flooding tube 5 and water output cylinder 6, the bottom of flooding tube 5 is communicated with a cartridge type filter screen 9, pump shaft 2 bottoms are stretched in the flooding tube 5 and are connected with the centrifugal impeller 7 of setting in the flooding tube 5, the axle center of the centrifugal impeller 7 that is connected with pump shaft 2 and the axle center of flooding tube 5 are eccentric structure, and flooding tube 5 and water output cylinder 6 are vertical structure, and the bottom of the bottom of flooding tube 5 and water output cylinder 6 is communicated with by connecting tube 8, connecting tube 8 is a vertical connection with water output cylinder 6, the sidewall of connecting tube 8 has weakened impact force of water flow to entering the certain resistance of water generates in the water output cylinder 6 in advance, has guaranteed that the hydraulic pressure that suction sleeve bore that is connected with water output cylinder 6 weakens, improved the working life of suction sleeve, and water outlet is more stable.
See Fig. 2, the central angle between the adjacent blades of centrifugal impeller 7 is 40 degree, has guaranteed that the centrifugal force of centrifugal impeller 7 rotation generations is imitated greatly, improved the efficient of drawing water by ridge pump, and water outlet is more stable.
