Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of hydrocyclone separators, in particular to an impact-resistant hydrocyclone separator. Background Art
[0002] When using a pump to transport a medium, the mechanical seal needs to be continuously flushed. This is because during the operation of the pump, the sealing chamber contains particles and impurities, which must be flushed. Otherwise, due to the precipitation of crystals and the precipitation of particle impurities, the dynamic and static rings of the mechanical seal will lose their floating properties and the spring will fail. The main method used is: a high-pressure chamber and a low-pressure chamber are provided in the pump. The high-pressure chamber stores a small amount of conveying medium pressurized by the pump impeller. The liquid inlet of the hydrocyclone is connected to the high-pressure chamber in the pump through a pipeline. The pressurized conveying medium is separated in the hydrocyclone. Finally, the liquid without solid particles after separation flushes the mechanical seal, and the solid particles separated by the hydrocyclone are connected to the low-pressure chamber in the pump through a pipeline.
[0003] The existing hydrocyclone separator is an integral casting structure, which has the following problems: when the medium enters the hydrocyclone separator under high pressure, it will impact the inner wall of the hydrocyclone separator, which is easy to damage the inner wall and is difficult to replace after damage.
