LY long shaft submerged pump

1, an overview of the

LY series long shaft submerged pump belongs to a single vertical pump absorption, is on the basis of absorbing foreign advanced technology, according to the market demand, independent design and development of new, energy conservation and environmental protection products.

2, scope of application

Applicable to power plants, chemical plants, sewage treatment plants conveying of various kinds of wastewater.

3, the structure characteristics of

1) using the newly developed hydraulic model, improve the efficiency of the pump.

2) using new and reliable way of the spindle. Long shaft section is divided into two or more section processing. Using a shaft end car threaded rod, and the other a shaft end thread inside the car, two axis through the threaded connection, outside of the spindle sleeve and join key fixed by its position. Such long axis by join key transmission torque, threaded rod axial force. To enhance the pump shaft alignment, reduce the long axis of the processing difficulty.

3) adopt unique balance cavity structure. Pump cover is balanced with the middle frame, cavity in the bottom of the cavity is equipped with atmospheric interlinked balance tube, pressure relief effect, reduce the axial force of the machine. Balance of granules medium from the pipe run at the same time, reduce particulate medium leak into the possibility of sliding bearing up. In the bottom of the sliding bearing has packing seal, further reducing particulate medium leakage may be up.

4) the use of packing seal and flushing pipeline structure. When pumping medium for containing small particles, the external processing. Connect a line from the outside world, the introduction of clean wash rinse each sliding bearing, lubricating sliding bearing, take away the heat generated by the friction pair, have the effect of cooling, at the same time, avoid solid particles into the friction pair.

5) bearing way: LY series adopts multi-point support method, liquid level above the angular contact ball bearings, liquid under each short axis has sliding bearing, sliding bearing is fixed in the middle supporting frame, intermediate support frame are connected to the support tube.
