Abstract
The utility model discloses a high efficiency self-suction pump which is suitable for water absorption of pools in tall buildings and industrial and mining enterprises. The water absorption mechanism of the pump comprises a water absorption screw rod (4) and an impeller (9). The impeller (9) is arranged in the middle of an inner separator plate (8) and an outer separator plate (10) provided with variable cross-section vortex grooves. After being connected through a candan universal joint (6), the screw rod (4) and the impeller (9) are arranged on a same rotary spindle (13). The pressure of the water pressure is increased; the pump lift is enhanced through the water absorption of the screw rod and the impeller and the variable cross-section vortex groove. The utility model has the advantages of small size and convenient operation.
Description
The utility model relates to the improvement invention of water pump, and particularly the improvement of peripheral pump and screw pump is invented, and is applicable to the pond pump water of high-rise building and industrial and mining enterprise
The known pump housing, such as submersible pump, peripheral pump normally by the pump housing, impeller and runner are formed, the runner of vortex groove all is prismatic usually.Screw pump also is by the pump housing, suction screw rod and runner are formed, during work, rotation by suction screw rod or impeller makes fluid constitute runner through the cavity between the pump housing and the pump cover, when impeller or screw rod rotation, because the centrifugal force of motion liquid absorbs circulation medium and output greater than the centrifugal force of motion liquid in the runner in impeller or the screw rod, but these pumps all belong to the one-level pulsating pump, the inside and outside vortex groove that an intercommunication is arranged every utmost point import and outlet of traditional design, all keep the gap more than 2 millimeters around it, that have even do not have interior external partition directly to cast out, eddy current holds and can't stand producing immediately and reflux in the pump when hydraulic pressure is high.And bulky, lift is low, of poor benefits
It is little that problem, the purpose of this utility model that exists in view of known technology aims to provide a kind of volume, lift height, profitable self-priming pump, to satisfy the needs of high building and industrial and mining enterprise's pond suction.
The utility model is that following mode is finished, in comprising the pump housing (1) with water intake and water outlet, its water-absorption mechanism adopts the secondary suction, the first order is the screw rod suction, the second level is the impeller suction, impeller (9) is contained in the interior external partition (10) with vortex groove and the centre of (8), the vortex groove of interior external partition (10) and (8) has one section variable section runner, this section variable section runner is that the ratio of establishing the degree of depth of finishing this section variable section runner by the partition wall on vortex groove and the vortex groove degree of depth is 1:3, screw rod (4) be contained on same the alternation of hosts of the family axle after impeller (9) is connected by universal joint cross, the primary structure of this pump improves suction capacity, secondary structure increases hydraulic pressure, can make pump reach low ebb self-priming and elevation conveying effectively.
This practicality is newly compared with known technology, it is little to have moulding, in light weight, suction capacity is strong, lift is high, instantaneous draining of energy and comprehensive suction, and another advantage of the present utility model is to replace submersible pump, deep-well pump is done the deep-well suction, and pump motor do not contact with horizontal plane, overcome motor for submerged pump and leaked because of long-term immersion and burn out, and this pump liquid that also can contain concentration 1CP-100000CP is carried simultaneously.

Accompanying drawing has been represented structure of the present utility model and embodiment, the pump housing (1) is directly installed on the motor, and water retaining ring is placed between motor front cover and the pump housing rear end on the main shaft (13), referring to Fig. 1, the inside that then mechanical seal ring (12) is placed on the pump housing (1) is stuck on the rotary main shaft (13) with back-up ring (11) and with it to be fixed, again internal partition (10) impeller (9) external partition (8) is contained on the rotary main shaft, the keyway alignment pin (7) of impeller, screw rod (4) universal joint cross (6) that the pin fourth hole of interior external partition will assemble with pin fourth location is again twisted solid on main shaft (13), after rubber sleeve (3) be placed on together use bolt (5) to be fastened on the pump housing (1) in the pump cover (4), seal ring is herein replaced by the extension rubber sleeve, the bottom valve that will have filter screen during use is contained in the suction inlet place of suction sleeve, present embodiment need to prove that especially suction screw rod (4) and impeller (11) are contained on same the rotary main shaft (13) through universal joint cross (6), interior external partition (8) and (10) of impeller (9) both sides are provided with vortex groove, wherein vortex groove is being provided with partition wall (14) near on the outlet port variable section runner, the ratio 1:3 of the degree of depth at this variable section runner partition wall place and the degree of depth of vortex groove
When pump working, electric machine main shaft drives the suction screw rod and rotates, suction pipe sucks cavity in the pump housing with water, current pump by the suction once more of impeller through the water intake of external partition (8), and one section variable section runner is arranged in the outlet port of the vortex groove of interior external partition, the working pressure that this has just improved hydraulic pressure improves lift.
Claims (3)
1, a kind of high-efficient self-priming pump, comprise the pump housing (1) with water intake and water outlet, it is characterized in that the water-absorption mechanism in the pump housing (1) is equipped with screw rod (4) and impeller (9), impeller (9) is contained in the interior external partition (10) with vortex groove and the centre of (8), and screw rod (4) is contained on same the rotary main shaft (13) that is connected by universal joint cross with impeller (9).
