Description

Slurry pump coupling

Technical Field

The utility model relates to the technical field of couplings, in particular to a slurry pump coupling.

Background

The slurry pump delivers a mixture of solid particles containing slag and water. In principle, however, slurry pumps are one type of centrifugal pump in which liquid is thrown from the center of the impeller toward the outer edge and is energized to leave the outer edge of the impeller at a high velocity into the volute casing. In the volute pump casing, the liquid is decelerated due to the gradual expansion of the flow passage, part of kinetic energy is converted into static pressure energy, and finally flows into the discharge pipeline at a higher pressure to be sent to a required place. When the liquid flows from the center of the impeller to the outer edge, a certain vacuum is formed in the center of the impeller, and the liquid is continuously pressed into the impeller because the pressure above the liquid level of the storage tank is higher than the pressure at the inlet of the pump, so that the liquid is mainly used for slurry transportation of systems such as dust removing water of a converter of a steel enterprise owner, blast furnace gas washing water, continuous casting turbid circulating water, steel rolling turbid circulating water and the like.

The slurry pump needs to use a coupling, which is also called a coupling, for firmly connecting a driving shaft and a driven shaft in different mechanisms together for rotation, and transmitting mechanical parts of motion and torque. Sometimes also to couple the shaft with other parts (e.g., gears, pulleys, etc.). The two halves are usually combined, respectively connected by a key or a tight fit, fastened at the two shaft ends, and then connected in some way. The coupling can also compensate offset (including axial offset, radial offset, angular offset or comprehensive offset) between two shafts due to inaccurate manufacturing and installation, deformation or thermal expansion during operation and the like; impact and vibration are alleviated.

However, in the prior art, slurry pump can cause muddy water to burst into the coupling under high-speed operation during transportation, and the slurry contains particulate matters, which can cause abrasion of the coupling, so that there is an urgent need for a coupling for slurry pump which can effectively prevent muddy water from entering.
