Abstract

The utility model relates to an automatic suction pump, in particular to an automatic suction volumetric pump with rubber wheels, which is composed of a pump body, an impeller, an axis, a seal assembly, a rolling bearing, a liquid inlet pipe and a liquid outlet pipe, etc. The utility model is characterized in that the impeller is made of rubber materials whose longitudinal section is similar to a petaled shape; the longitudinal section of the impeller and the inner wall of the pump body is movable fit without gap; a power input shaft comprises a clutch, a pulley, a conicity disc and a turnbuckle pull rod. The utility model can be controlled by hands and is widely used for conveying liquid in the field of industry and agriculture, in particular to the greening of factories, countryside and cities and the deinsectization, disinfection, jetting agrochemical or sprinkling of the garden management. The pump can be used with a two-wheeled tractor together and can be used in ports and families.

Description

Automatic suction volumetric pump with rubber wheels

The utility model relates to a kind of improved self-priming pump, particularly rubber wheel self-priming displacement pump.

Existing self-priming pump mainly is made of the complicated pump housing, impeller, bearing support and mechanical seal etc., its self-priming effect relies on and forms suction chamber, water storage room, volute body and air-water separation chamber in the complicated pump housing, complex structure, make difficulty, volume is big, flow is little, lift is low, and self-priming starting is slow, irritates liquid in advance, thereby cost height, efficient are low.

The purpose of this utility model provides the rubber wheel self-priming displacement pump that a kind of volume is little, flow is big, lift is high, the self-priming starting is fast.

The utility model is achieved in that impeller is used rubber wheel instead in the pump housing, endoporus is lined with spline housing and pump shaft spline fitted, because rubber tree leaf has soft and flexible characteristics, make between blade and the pump housing inwall no gap movingly, sealability is fabulous like this, can recover nature automatically after the dismounting simultaneously, existing superior self-priming performance has advantage easy to loading and unloading again.At the power intake of axle, clutch, swivel nut pull bar, belt pulley, interior external taper dish are installed.Belt pulley is fixed on the axle with pin, and the inner cone scale is arranged on the belt pulley, and the outer cone scale then is associated in one with swivel nut, regulates outer axially mobile with the swivel nut pull bar, as long as Joystick is pulled to the left and right can be made the applying of outer cone scale and separate belt pulley, make wheel rotation and stop during work.

The face seal components of axle is very important, adopts compositions such as stationary ring, spring and rotating ring, and stationary ring employing sintered ceramic, and rotating ring forms for the graphite press process.Because self-lubricating property is good, friction factor is little, so long service life, self-priming performance are good, and volume is little, and flow picks up greatly, certainly that starting is fast, lift is high, and lift can reach more than 30 meters when rotating speed is 1450 rev/mins.Be widely used in industrial or agricultural and carry liquid, as factory, rural area, urban afforestation, garden management, the ideal tools of agricultural chemicals or sprinkling irrigation is sprayed in the deinsectization sterilization, and can with the supporting use of two wheel tractor, also can be used as harbour and home-use pump.

Below in conjunction with accompanying drawing the utility model is further described.

Fig. 1 is the whole sectional view of the utility model.

Fig. 2 is the utility model wing pump stereogram.

With reference to Fig. 1, Fig. 2, installation impeller shaft (4), impeller shaft are carved with spline on (4) in the brass system pump housing (1), cooperate stressed joint with axle sleeve (3), axle sleeve (3) closely is connected with the impeller (2) that the rubber compacting forms, in pressing process, axle sleeve (3) is carried out together as inner core, make it be pressed into one, simultaneously, the flexuose protruding ring is made on the surface of axle sleeve (3), makes itself and the tight interlock of rubber impeller.Its endoporus has the groove that matches with splined shaft.It is petal that impeller (2) is made longitudinal section with neoprene.

Shaft end seal spare (5) adopts stationary ring, rotating ring and spring structure, guarantees sealability, and stationary ring adopts sintered ceramic, rotating ring to adopt the graphite compacting to form.

Impeller (2) does not have the gap movingly with the pump housing (1) inwall, go up power intake at axle (4) clutch (8) is housed, belt pulley (9), tapering dish (10) and swivel nut pull bar (12), belt pulley (9) are made for aluminum alloy, the inner cone scale is arranged on it, belt pulley (9) is fixed on the axle with pin, outer cone scale and swivel nut join together, regulate with swivel nut and axially move outward, during work as long as operating grip (15) though about pull the tapering dish and fit and separate.

The pump housing (1) and base (14) integral cast, liquid inlet pipe (11) is contained on the pump housing (1) with drain pipe (13), and liquid inlet pipe (11) and the necessary good seal in the joint of the pump housing (1) promptly can influence lift if any leaking.

The pump housing (1), axle sleeve (3), axle (4) adopt brass material to make, if be used for aggressive medium.Then will make with stainless steel material, perhaps metal coated plastics (as fluoroplastic) or lining are to improve corrosion-resistant degree.

The sealing of fourth shape (6) and rolling bearing (7) are housed on the axle (4) of power intake, turn round steadily and the sealability of clutch device to guarantee axle (4).
