Abstract
A self-priming screw electric pump is composed of a pump body with end cover and cover, and features that the rotor of motor in pump body is matched with bearing, mechanical seal and skeleton oil seal and connected with universal joint in water sucking chamber, the screw rod is connected to universal joint and is in friction with screw rod stator, the water sucking and discharging joints are installed to water sucking chamber, and one end of screw rod stator is in water sucking chamber and another end is communicated with water discharging joint. It has simple structure, convenient use, suction lift up to 9m and lift up to 50 m. The water taking device has wide application range and is an ideal water taking device.
Description
The utility model relates to a kind of water pump.
In background technique, a kind of self prime pump is arranged, attraction force and centrifugal force that it mainly utilizes the impeller high speed rotating to produce are realized attracting liquid and are carried liquid, before each start, must be in suction chamber topped up with water, it is inhaled, and journey is low, and lift is not high yet, and the water outlet time is slow, be not suitable for use in 50 meters building water lifts about height, application area is less.
The purpose of this utility model is to provide a kind of water outlet fast, inhales journey height, lift height, self-priming screw rod electric pump easy to use.
The purpose of this utility model is achieved in that it comprises the pump housing, be connected with end cap and case on the pump housing, it is characterized in that the rotor in the pump housing matches with bearing, mechanical seal and outside framework oil seal, and join with universal joint in the suction chamber, be connected with screw rod on the universal joint, screw rod rubs mutually with the screw rod stator and closes, and suction joint and water outlet joint are housed on the suction chamber, one end of screw rod stator is positioned at suction chamber, and its other end communicates with the water outlet joint.
Use in the area of simple in structure, reasonable in design, the suitable water level of the utility model more than 9m, and can deliver to the 50m height to water with on the interior building, and application area is wider.
In conjunction with the accompanying drawings and example, the utility model is further described as follows:
Fig. 1 is a structural representation of the present utility model
Description of drawings: case-1, motor ventilating fan-2, end cap-3, the pump housing-4, electric capacity-5, rotor-6, motor-7, handle-8, grease chamber-9, oiling screw-10, grease chamber's end cap-11, suction chamber-12, suction joint-13, universal joint-14, screw rod-15, screw rod stator-16, water outlet joint-17, foot pad-18, flat pad A-19, flat pad B-20, outside framework oil seal-21, flat pad C-22, mechanical seal-23, bearing-24,25.
In Fig. 1: the utility model comprises the pump housing 4, the pump housing 4 is connected with end cap 3 and case 1, motor ventilating fan 2 is positioned at case 1, rotor 6 in the pump housing 4 matches with bearing 24, mechanical seal 23 and outside framework oil seal 21, and link with universal joint 14 in the suction chamber 12, grease chamber 9 is at motor 7 and suction chamber 12 between the two, be connected with screw rod 15 on the universal joint 14, screw rod 15 rubs mutually with screw rod stator 16 and closes, suction joint 13 and water outlet joint 17 are housed on the suction chamber 12, one end of screw rod stator 16 is positioned at suction chamber 12, and the other end is connected with water outlet joint 17.During use, driving universal joint 16 by rotor 6 rotates, meanwhile, be connected in to joint 14 the also corresponding rotation of screw rod 15,, cause the air in the suction chamber 12 fewer and feweri because screw rod 15 can be discharged through screw rod stator 16 air in the suction chamber 12 when rotating from water outlet joint 17, until water is sucked into suction chamber 12 from suction joint 13, along with the fast rotational of screw rod 15, the water in the suction chamber 12 can save 17 from water outlet again and discharge, thereby reaches the effect of water intaking.
