Problems solved by technology
If the material is too hard, it is easy to break, if it is too soft, it will not be able to process a high-precision surface. If the tolerance of the end face is too small, it will easily be stuck due to thermal expansion. Had to stop the production line to replace the pump equipment, causing great direct or indirect losses

The invention relates to a gear pump with a new structure. An external thread suction inlet and an external thread outlet are positioned in two outer sides of a pump body, a dynamic sealing disk is arranged between a driving metallurgical gear and a driven alloy gear and a front outer end cover, one end of a cylindrical master spring is fixed at a dynamic disk master convex platform on the back surface of the dynamic sealing disk, the other end of the cylindrical master spring is props against the inner side surface of the front outer end cover in a pressing manner, one end of a cylindrical slave spring is fixed at a dynamic disk slave convex platform on the back surface of the dynamic sealing disk, the other end of the cylindrical slave spring props against the inner side surface of the front outer end cover in a pressing manner, a dynamic disk outer groove is formed in the dynamic disk outer edge of the dynamic sealing disk and provided with an outer sealing ring, the dynamic sealing disk is provided with a dynamic disk master hole and a dynamic disk slave hole, the dynamic disk master hole and the dynamic disk slave hole are respectively provided with a dynamic disk hole groove with the same size, an inner sealing ring is arranged in each dynamic disk hole groove, a static sealing disk is arranged between the driving metallurgical gear and the driven alloy gear and a rear outer end cover, two different alloy materials are adopted for the driving metallurgical gear and the driven alloy gear, and both the dynamic sealing disk and the static sealing disk adopt a composite material formed by a Fe / Al intermetallic compound and Al2O3.
Description
technical field [0001] The invention relates to an energy conversion rotary positive displacement pump which converts mechanical energy into liquid pressure energy, in particular to a gear pump with a new structure. Background technique [0002] Rotary positive displacement pumps have the advantage of high efficiency, but their efficiency is significantly reduced after long-term wear and tear. The main reason for the above defects is that the end face movable isolation between the high pressure chamber and the low pressure chamber cannot play an effective sealing role. In engineering, it is difficult to find a material that can meet all the conditions of a specific working condition and have good cost performance. Therefore, in the past, people often used various surface coating methods to solve this problem; that is, to make full use of two or more materials It can be achieved by combining performance, or through some surface strengthening treatment to replace higher-priced...
