Description

Technical Field

[0001] The utility model relates to the technical field of high-pressure plunger pumps, in particular to a shock absorbing mechanism of a high-pressure plunger pump. Background Art

[0002] Due to the characteristics of high interception rate, high water production rate and low pollution frequency, the disc-tube reverse osmosis process has been widely used in the field of high-concentration sewage treatment, especially high-concentration organic matter and high-salinity sewage, such as landfill leachate. The core components of the disc-tube reverse osmosis equipment include the chassis unit, the distribution cabinet unit, the buffer tank unit, the filter unit, the sand filter unit, the high-pressure pump unit, the instrument rack unit, the membrane column unit, the high-pressure pipeline unit, and the tank system unit. Among them, the high-pressure pump unit plays a vital role. The process uses the principle of osmotic pressure, and the high-pressure pump provides a force to overcome the osmotic pressure to the membrane assembly, so that the clean water is separated from the concentrated water side through the selective permeability of the semi-permeable membrane, and finally achieves the effect of water purification. During the use of the high-pressure plunger pump, due to the movement of the plunger, the high-pressure pump vibrates strongly. If no shock absorption and protective measures are taken, it is easy to cause the front-end pipeline of the high-pressure pump to break.

[0003] For example, Chinese patent CN 219139276 U discloses a device for reducing vibration of a high-pressure plunger pump, which consists of a spring safety valve, a high-pressure plunger pump, a pump inlet regulator, a stainless steel bracket, a motor, a rubber shock absorber, an outlet pulse damper, and a belt.

[0004] The above-mentioned device for reducing the vibration of the high-pressure plunger pump still has certain shortcomings. It reduces the vibration of the high-pressure plunger through the rubber shock absorber and the outlet pulse damper. The pressure after the high-pressure plunger pump is stable, and the stability of the equipment operation is improved. However, after long-term use, the rubber shock absorber will be aged, corroded by oil, sunlight and chemical properties, which may lead to its performance degradation. Therefore, this application proposes a shock absorbing mechanism for a high-pressure plunger pump to solve the above problems. Utility Model Content
