Description

[0002] The Inner Mongolia section of the Yellow River is 843.5 kilometers long, accounting for about one-sixth of the total length of the Yellow River. The Yellow River irrigation in the Hetao region began in the Qin and Han Dynasties, and has a history of more than 2,000 years. With the nourishment of the Yellow River water, the Hetao region, with an average annual precipitation of less than 200 mm and an average annual evaporation of more than 2,000 mm, has become a large agricultural area. In recent years, the direct filtration irrigation equipment for diverting the Yellow River has become the mainstream equipment for irrigation with Yellow River water. The main structure of the direct filtration irrigation equipment for diverting the Yellow River includes diesel engine components, centrifugal pump components, cyclone filter components, precision filter components and fertilizer tank components. Due to the spatial structure layout factors, an elbow is usually designed between the water inlet pipe of the centrifugal pump component and the cyclone filter component for connection. During the production and assembly of the equipment, the installation of the elbow is It is usually the last step. Since the water inlet pipe of the cyclone filter assembly needs to enter the water tangentially, it has very high spatial positioning requirements. Therefore, when installing the elbow, it is often unable to connect due to the large positioning error. If normal installation is to be achieved, the positioning tolerance of each connecting component of the entire equipment must be strictly controlled, resulting in production difficulties and excessively high production costs. Even if the installation is successful, due to mechanical vibration, stress concentration is prone to occur in the rigid connection part, and parts are prone to wear and leakage. At the same time, the elbow position is washed by the Yellow River water with a lot of sediment, wears quickly, and the elbow needs to be replaced regularly. The traditional flange connection method has a slow elbow replacement speed, which is time-consuming and labor-intensive, and needs to be improved urgently. Utility model content:
