Abstract
The utility model discloses a pump head for a centrifugal pump, which can suck and discharge liquid. The utility model is suitable for a work mode that the pump head is directly plunged into liquid to work, and is composed of a casing of the pump head (1), an impeller (3), screw caps (2), a connecting body (5) and screw bolts (7). Work the utility model works, a shaft drives the impeller to rotate to force the liquid continuously to enter in from a liquid inlet to be exhausted from a liquid discharge port, completing pumping and discharging process.
Description
The utility model relates to a kind of brand-new centrifugal pump pump head, is suitable for the centrifugal pump pump head and directly slips into pump drainage liquid in the liquid.
Existing centrifugal pump pump head has horizontal, vertical two kinds, but they have a common characteristic, and centrifugal pump pump head center is to perforation, one end is a liquid inlet, and the other end is the shaft sealing end, needs sealing, otherwise meeting leakage body, influence is worked normally, particularly horizontal centrifugal pump, when centrifugal pump pump head sealing position leakage body, tightening seal packing and replacing packing, if liquid contains certain solid phase particle, the sealed packing life-span is shorter, and the position of changing packing is narrow, is difficult for on-the-spot the replacing.
Task of the present utility model is to provide a kind of easy to use, and the centrifugal pump pump head has only liquid outlet of a liquid entering hole, the centrifugal pump pump head that axle need not seal.
The utility model by centrifugal pump pump head housing (1), nut (2), impeller (3), axle (4), hollow connecting body (5), liquid entering hole (6), screw rod (7), liquid port (8), form.
Task of the present utility model is finished as follows, has two holes in vain in the centrifugal pump pump head housing (1), on one side centerline direction is a side opening, Yi Bian sealing, housing (1) is gone up another hole and is liquid port (8), is connected with discharge pipe.Use screw rod (7) on the side opening, fastening hollow connecting body (5), have liquid entering hole (6) on the hollow connecting body (5), an impeller (3) that the centre is porose is housed in the centrifugal pump pump head housing (1), impeller (3) is through axle (4) and goes up with nut (2) and tight, when driven by motor axle (4) revolves spool, axle (4), impeller (3) rotation, impeller (3) on every side liquid in rotation and produce centrifugal force, along rotation in the centrifugal pump pump head housing (1), discharge from liquid port (8), when impeller (3) when negative pressure appears in the center, the outer liquid of centrifugal pump pump head housing (1) just enters in the housing (1) from the connecting body (5) that liquid entering hole (6) enters through hollow, again liquid port (8) discharge from the housing (1).When continuous rotary blade (3) liquid just enters continuously and discharges in the centrifugal pump pump head.
Below with reference to accompanying drawing the utility model is described in further detail:
Fig. 1 is a structural representation of the present utility model.
On the hollow centrifugal pump pump head housing of making by cast steel with reference to Fig. 1, (1) side opening and a liquid port (8) are arranged, hollow connecting body (5) is housed on the side opening, hollow connecting body (5) is fastened on the side opening of housing (1) with screw rod (7), has liquid entering hole (6) on the hollow connecting body (5).In the centrifugal pump pump head housing (1) of hollow impeller (3) is housed, the porose axle (4) that is through is gone up and is compressed by nut (2) in the middle of the impeller (3), prevent that impeller (3) from returning, impeller (3) can rotate with axle (4) in centrifugal pump shell head capsule body (1), when driven by motor axle (4) rotates, impeller (3) on the axle (4) rotates thereupon, when impeller (3) when liquid being arranged on every side, impeller (3) rotation forces flow of fluid generation centrifugal force to flow out from liquid outlet (8), and impeller (3) center produces the liquid inflow that negative pressure is located liquid entering hole (6), and continuous operation is advanced and gone out in realization.
When using, the centrifugal pump pump head slips in the liquid, actuating motor drives axle (4) rotation, and axle (4) drives impeller (3) rotation on the axle (4), and impeller (3) drives liquid in rotation and produces centrifugal force, force liquid to be discharged to liquid outlet (8), impeller (3) center produces negative pressure simultaneously, forces near the liquid of liquid entering hole (6) to flow into from liquid entering hole (6) and replenishes up, and motor drives impeller (3) is rotation continuously, liquid will be discharged continuously, reaches the into purpose of discharge opeing body.
Claims (1)
- A centrifugal pump pump head of forming by centrifugal pump pump head housing (1), nut (2), impeller (3), axle (4), connecting body (5), liquid entering hole (6), screw rod (7), liquid port (8), it is characterized in that having two holes in vain in the pump head housing (1), the side has a hole to link to each other with screw rod (7) with hollow connecting body (5), it is liquid entering hole (6) that hollow connecting body (5) is gone up porose, and it is that outage (8) is connected with discharge pipe that pump head housing (1) is gone up another hole.
