Pulse damper

Abstract

The invention provides a pulse damper. The pulse damper comprises a body, an elastic film, a feeding pipe, a discharging pipe and an air nozzle. A cavity is defined in the body. The elastic film is arranged in the cavity and divides the cavity into a first chamber and a second chamber. The feeding pipe and the discharging pipe are oppositely arranged and communicate with the first chamber. The airnozzle communicates with the second chamber. According to the pulse damper of the embodiment, when the material pressure tends to the peak pressure, the material pressure can be reduced; when the material pressure tends to the valley pressure, the material pressure can be offset; and accordingly, the material pressure is basically constant.

Description

technical field [0001] The invention relates to a pulse damper. Background technique [0002] During the transportation of liquid or solid powder materials, if the equipment for pumping materials adopts positive displacement pumps such as diaphragm pumps, continuous pulses of materials will be formed at the discharge port, and the material pulses are essentially periodic and continuous changes in the pressure of materials in the discharge pipe. . The pressure pulse will affect the outlet pipe and the outlet end. If the material velocity is too high, it will cause friction in the pipe, and even the elbow part of the pipe will be worn through by the material, resulting in pipeline damage and interruption of material delivery. When pumping paint-like materials, pulses can cause uneven spray at the outlet. When pumping powder materials, the pulse will increase the dust at the outlet and reduce the efficiency of the rear-end dust collection equipment. [0003] The existing tec...
