10 times of degree.Using this structure, the counterbalance effect of fin is more preferable.
The the first connection convex block for forming annular on the outer wall of above-mentioned suction line along its circumferential direction, outside the inner end of the water inlet pipe
The second connection convex block of annular is formed on wall along its circumferential direction；
The locking member includes M block latch segment, and M is the natural number more than or equal to 2, and it is recessed that locking is offered on the latch segment
Slot, the suction line are docked with the inner end of the water inlet pipe, and the latch segment is straddled to be connected in the first connection convex block and second
It connects on convex block, the first connection convex block and the second connection convex block protrude into the locking groove, and the latch segment passes through locking
Bolt connect convex block with described first or the second connection convex block is fixedly connected.Using this structure, when disassembly, it is only necessary to will be outside pipeline
Latch segment within the scope of 180 ° is removed, and remaining latch segment can be by water inlet pipe and suction line point after only needing to unscrew on bolt
It opens, thus greatly facilitates installation and removal.
It is set on the outer wall of above-mentioned shell there are four reservation member, four reservation members are uniform along the helical circumferential of the shell
Distribution；
The reservation member includes that the cylinder of two faces setting reserves column, and two reserved columns are located at the shell
The inner end of the two sides of body, two reserved columns is fixedly connected with the outer wall of the shell respectively.It, can be according to need using this structure
Will on reserved column turn hole, for connecting other pipelines or exhaust etc., when pump is connect with driving device, can as needed it is random more
Change the installation direction of pump.
The utility model has the advantages that can arbitrarily replace the installation direction of pump as needed using the utility model, pump housing inner impeller has
For the fin of balancing axial pressure, to really can effectively prevent silt in the smoothness for depositing, ensuring to flow, and pumps and intake
The connector of pipe uses a kind of clip that structure is special, greatly facilitates installation and removal.
