Description

Three-dimensional mixed flow pump

Technical Field

The utility model belongs to the technical field of the mixed flow pump, concretely relates to three-dimensional mixed flow pump.

Background

A mixed flow pump is a pump between a centrifugal pump and an axial flow pump. The specific speed of the mixed flow pump is higher than that of the centrifugal pump and lower than that of the axial flow pump, and is generally between 300 and 500. Its lift is higher than the axial-flow pump, but the flow is smaller than the axial-flow pump and larger than the centrifugal pump. When the prime motor drives the impeller to rotate, the action on the liquid is centrifugal force and axial thrust, the centrifugal pump and the axial flow pump are integrated, and the liquid obliquely flows out of the impeller. It is therefore a pump between a centrifugal pump and an axial flow pump. The centrifugal pump and the axial flow pump have the advantages of simple structure, wide high-efficiency area and convenient use.

After the mixed flow pump is used for a long time, the inside of the pump body is washed including the impeller in order to avoid sundries accumulating in the pump body, so the blade is difficult to carry out thorough washing when the mixed flow pump is shut down because sundries are easy to adhere to the blade, and the end cover of the pump body is required to be opened by detaching the impeller, thereby wasting time and labor, increasing the workload of workers, and needing to update the design and solve the problems.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

The utility model provides a as shown in fig. 1-4 a three-dimensional mixed flow pump, set up in the pivot 2 of the pump body 1 inside with rotating including the pump body 1, 3 joints of locating pin have axle sleeve 4 in the outside of pivot 2, axle sleeve 4 passes through 5 fixed mounting in the tip of pivot 2 of location structure, the welding has combination formula impeller 6 on the lateral wall of pivot 2, combination formula impeller 6 comprises lagging 61, movable blade 62 and shell fragment 63, movable blade 62 slides and sets up in the inside of lagging 61, the both ends of shell fragment 63 weld with the lower extreme of movable blade 62 and the bottom of lagging 61 respectively. At the mixed flow pump during operation, motor output power drives pivot 2 and rotates, pivot 2 drives combination formula impeller 6 through axle sleeve 4 and rotates, because centrifugal effect, movable vane 62 slides towards the direction of keeping away from lagging 61, form the blade of complete impeller, realize defeated material work, when needing to dismantle the impeller and clear up after the blendor is shut down, resume former long pulling movable vane 62 through shell fragment 63 and slide to the inside of lagging 61, make combination formula impeller 6's blade area reduce, through dismantling positioning mechanism in pump body 1 feed inlet position, convenient dismantle combination formula impeller 6 gets off, take out in the pump body 1, clear up.

Positioning mechanism comprises positioning baffle 51, tip gland 52, positioning bolt 53 and location screw 54, positioning baffle 51 fixed mounting supports the left end that axle sleeve 4 in the outside of pivot 2, tip gland 52 supports the right-hand member of axle sleeve 4 in the right-hand member of pivot 2 through locating pin 3 joint, and positioning bolt 53 runs through the positioning screw 54 threaded connection that tip gland 52 and pivot 2 tip were seted up, and the cooperation through positioning bolt 53 and positioning screw 54 makes fixed connection between tip gland 52 and the pivot 2 together, and cooperation positioning baffle 51 supports the both ends of axle sleeve 4, avoids axle sleeve 4 to take place axial slip on pivot 2.
