[0002] A process pump is a centrifugal pump that transports materials and is used in many industries such as petrochemicals, chemical fiber, chemical industry, electric power industry, and environmental protection projects. When working, the impeller rotates to form a negative pressure area in the center of the impeller, and the medium in the inlet pipe is transported from the relatively high pressure area in the inlet pipe to the negative pressure area in the center of the impeller. The medium is then pressed out from the pump outlet by the action of the impeller blades.

[0003] According to the application number 202320204835.3, a chemical process pump is disclosed. When the bending angle of the blades can be changed as needed, a sleeve can be installed on the outer surface of the twisting block from the water outlet, and then the screw is rotated. In this way, the rotating ring is driven to move by the screw, and the blades can be driven to rotate around their own rotating axis through the transmission rod, thereby changing the angle of the blades and the shape of the flow channel between the blades, so that the device can spray different media as needed.

[0004] The following problems still exist in actual use:

[0005] The internal structure of the pump body needs lubrication. The main method of lubrication is manual lubrication after a certain maintenance cycle according to the working condition of the equipment. The oil filling port structure is used to add lubricating oil. The existing oil filling port structure is fixed and not easy to disassemble. After long-term use, dirt accumulates, which hinders subsequent use. In addition, the existing process pump does not have an anti-backflow function, and backflow is prone to occur, affecting the water flow rate. Utility Model Content

[0025] By providing a snap-on assembly 5, the oil filling port assembly 3 can be installed and disassembled by snap-on means, which makes it convenient for personnel to clean the oil filling port structure and prevent it from accumulating dirt. During disassembly, personnel only need to push the two toggle bars 504 outward, and cooperate with the connecting rod 503, the snap-on block 502, and the first spring 501 to disconnect the snap-on relationship between the oil filling port assembly 3 and the mounting block 4, and then the oil filling port assembly 3 can be pulled out upwards. The operation is simple and easy to understand.

[0030] In the utility model, the working principle of the device is as follows:

[0031] When the pump body 1 is running, the medium is sucked in through the water inlet 8 and then flows into the guide tube 901. The medium impacts the sealing plug 904 and then disperses, and then flows into the pump body 1 and the water outlet 10 through the circulation cavity 905. When the water flows back, the backflowing water impacts the sealing plug 904, so that the sealing plug 904 is forced to move toward the direction of the water inlet 8, so that the sealing plug 904 blocks the water inlet 8, and then the backflowing water will flow back into the pump body 1 for transportation, thereby realizing the anti-backflow function;

[0032] When the oil filling port assembly 3 is used for a long time and dirt is accumulated inside, and the oil filling port assembly 3 needs to be disassembled for cleaning and maintenance, the personnel pushes the two toggle bars 504 outward, driving the connecting rod 503 to move, and at the same time driving the clamping block 502 to move, so that the first spring 501 is compressed, and at the same time the distance between the clamping block 502 and the clamping groove 7 is increased, and the clamping relationship is disconnected, and then the oil filling port assembly 3 can be pulled out upward for cleaning and maintenance. The operation is simple and easy to understand. Conversely, the oil filling port assembly 3 is inserted into the mounting block 4, so that the clamping block 502 enters the clamping groove 7, and is clamped and fixed, so that the oil filling port assembly 3 can be re-fixed, and when the clamping block 502 moves, it can drive the slider 506 to slide in the slide groove 505, making its movement smoother and increasing stability.
