[0002] Centrifugal pumps are commonly used in daily life. They use the rotation of the internal impeller to generate centrifugal force to transport liquids. During use, it is often necessary to adjust the flow rate of the outlet. The existing commonly used methods are regulating valves and some regulating devices. The regulating valve includes a rotatable turntable. The rotation of the turntable drives the valve core to move downward to block the outlet to a certain extent. However, the purchase cost of the regulating valve is relatively high, and the purchase cost of the regulating device is relatively low. However, the regulating valve can only move in the vertical direction and cannot meet the needs of use very well.

At this time, the fastening piece and the regulating pipe are tightly against each other, and the initial state of the bevel gear and the regulating seat is at the position farthest from the connection between the water outlet and the regulating pipe.

[0019] S2: For vertical position adjustment, first rotate the abutting piece in the opposite direction to separate its lower end from the adjusting tube, and then rotate the gear ring. The gear ring rotates to drive the gear 1 and the one-way bearing 1 on the reciprocating screw 1 to rotate, and then drives the reciprocating screw 1 to rotate.

[0021] S4: During the horizontal adjustment process, the gear seat is in a fixed state, and the movement of the bevel gear will drive gear 2 to rotate. The rotation of gear 2 drives reciprocating screw 3 to rotate through the circular shaft. The rotation of reciprocating screw 3 drives the mounting plate to move outward through ball nut 3.

[0022] Compared with the prior art, the present invention has the following advantages:

[0023] 1: Use the adjustment seat 1 and the adjustment seat 2 to adjust the flow rate at the water outlet. At the same time, the movement of the adjustment seat 1 and the adjustment seat 2 in the vertical and horizontal directions is easy to operate. The rotation in the required direction can be quickly achieved by hand.

A method for adjusting a centrifugal pump, comprising the centrifugal pump according to claim 8, characterized in that: The following steps are also included: S1: When the pump (1) is working, water flows into the regulating pipe (3) through the water outlet (2), at which time the abutting member (16) and the regulating pipe (3) are tightly abutted, and the bevel gear (24) and the regulating seat (29) are initially located at a position farthest from the connection between the water outlet (2) and the regulating pipe (3); S2: Position adjustment in the vertical direction, first rotate the holding member (16) in the opposite direction to separate its lower end from the adjusting tube (3), then rotate the gear ring (15), the gear ring (15) rotates to drive the gear (14) and the one-way bearing (13) on the reciprocating screw (11), thereby driving the reciprocating screw (11) to rotate, the reciprocating screw (11) rotates to drive the connecting rod (18) to move downward through the one-way bearing and the moving block (17), the connecting rod (18) moves downward through the slider (19) and the gear seat (20), and drives the adjusting seat (21) to move downward to the desired height; S3: Position adjustment in the horizontal direction, the gear ring (15) is rotated in the reverse direction, at which time the one-way bearing 1 (13) and the gear 1 (14) on the transmission shaft (12) rotate, the transmission shaft (12) rotates through the cooperation of the two bevel gears (24) to drive the reciprocating screw 2 (23) to rotate, the reciprocating screw 2 (23) rotates through the cooperation of the ball nut 2 and the moving block 2 (25) to drive the fixed rod (26) to move, the fixed rod (26) moves and drives the adjustment seat 1 (21) to move, and the distance between the adjustment seat 1 (21) and the connection between the water outlet (2) and the adjustment pipe (3) is adjusted; S4: During the horizontal adjustment process, the gear seat (20) is in a fixed state, and the movement of the bevel gear (24) drives the second gear (37) to rotate. The rotation of the second gear (37) drives the reciprocating screw rod (36) to rotate through the circular shaft (35). The reciprocating screw rod (36) drives the mounting plate (40) to move outward through the ball nut (3). The movement of the mounting plate (40) drives the adjustment seat (29) to expand outward through the push rod (39).
