Description

Technical Field

[0001] The utility model relates to the technical field of rotor pumps, in particular to a rotor pump capable of lifting oil at a low speed and high efficiency. Background Art

[0002] A rotary pump is a type of positive displacement pump, primarily consisting of a rotating rotor and a stationary pump body. It lacks suction or discharge valves, instead changing its working volume through the relative motion between the rotor and pump body. Liquid is expelled through the squeezing action of the rotating rotor, while leaving space on the other side, creating a low pressure that allows liquid to be continuously drawn in. Rotary pumps can be categorized by their structure and principle into gear pumps, screw pumps, rotary piston pumps (cam pumps, Roots pumps), flexible impeller pumps, vane pumps, and hose pumps.

[0003] According to application number 202211542191.5, a rotor pump sealing structure includes: an outer shell and a cover plate, wherein the outer shell and the cover plate realize sealing for the northern part of the pump body, wherein a rotating shaft is rotatably mounted in the middle of the cover plate, and a positioning block is provided in the middle of the rotating shaft to realize fixed connection for the impeller blades, and the sealing mechanism includes a shaft seal and an end face seal, wherein the shaft seal includes a middle sealing plate and an upper sealing plate, wherein the rotating shaft is provided with an upper sealing plate at the right end inside the outer shell, and a middle sealing plate is provided at the left end of the rotating shaft inside the cover plate. The sealing mechanism includes a shaft seal and an end face seal, wherein the shaft seal includes a middle sealing plate and an upper sealing plate, wherein the upper sealing plate realizes sealing between the left side of the rotating shaft and the outer shell, and the middle sealing plate realizes sealing between the middle part of the rotating shaft and the contact surface of the cover plate.

[0004] In this case, the outer shell and cover are fixed together using bolts. A sealing ring is installed on the fixing surface in the middle of the outer shell and cover to improve sealing during compression and extrusion. Sealing strips are installed on the outer contact surfaces of the outer shell and cover. Combined with the sealing ring, they seal the end faces of the equipment and better seal the pump body. However, the sealing ring in this case is placed directly in the middle of the outer shell and cover, without any support or limit, making it difficult to install. Utility Model Content

[0014] 2. This low-speed, high-efficiency oil-lifting rotor pump uses a fixing mechanism to move the two slides toward each other, causing one end of the fixing block to leave the slot, and then insert the bottom end of the protective cover into the slot. After that, the two slides are released, and the two slides will move in opposite directions due to the elastic force of the second spring, so that one end of the two fixing blocks can enter the fixing groove in the protective cover to fix the protective cover. This changes the traditional bolt fixing method and is more efficient. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The utility model provides the following technical solutions:

[0026] Example 1

[0027] See also Figure 1-4 The utility model provides a technical solution: a low-speed and high-efficiency oil-lifting rotor pump, comprising a base 1 and a protective cover 3, a pump body 2 is fixedly connected to the top of the base 1, an oil pipeline 4 is fixedly connected to the right side of the front of the pump body 2, a flange 5 is fixedly connected to the front end of the oil pipeline 4, a sealing mechanism 6 is provided on the front of the flange 5, and a fixing mechanism 7 is provided on the top of the base 1.

[0028] The sealing mechanism 6 includes an annular groove 61, which is provided on the front of the flange 5. A sealing ring 62 is inserted into the annular groove 61. A first slide groove 63 is provided on the front of the flange 5. A fixed plate 65 is connected to the first slide groove 63 for sliding up and down. A connecting plate 64 is fixedly connected to the back of the flange 5. A guide rod 66 is connected to the top of the connecting plate 64 for sliding up and down near the back. A first spring 67 is sleeved on the surface of the guide rod 66 between the fixed plate 65 and the connecting plate 64. Second slide grooves 68 are provided on the left and right sides of the first slide groove 63.

[0029] The bottom end of the guide rod 66 extends to the bottom of the connecting plate 64 , and the bottom end of the guide rod 66 is fixedly connected to the top of the fixed plate 65 . The top end of the first spring 67 is fixedly connected to the lower part of the fixed plate 65 , and the bottom end of the first spring 67 is fixedly connected to the top of the connecting plate 64 .

[0030] The left and right sides of the fixing plate 65 are protruding and slidably connected to the second slide groove 68. There are four groups of first slide groove 63, connecting plate 64, guide rod 66, first spring 67 and second slide groove 68, and they are arranged in an array on the front of the flange 5.

[0031] Example 2

[0032] See also Figure 5-6 , and on the basis of embodiment 1, a fixing mechanism 7 is further obtained.

[0033] The fixing mechanism 7 includes a slot 71, which is symmetrically arranged on the top of the base 1 in a front-to-back manner. A rectangular slot 72 is symmetrically arranged on the top of the base 1 in a front-to-back manner. A third sliding slot 73 is symmetrically arranged on the left and right sides of the rectangular slot 72. A slider 77 is connected to the third sliding slot 73 for sliding forward and backward. The end of the slider 77 away from the third sliding slot 73 is fixedly connected to a slide plate 74.

The two slides 74 will move toward each other in opposite directions due to the elastic force of the second spring 75, so that one end of the two fixing blocks 76 moves into the fixing groove 78 in the protective cover 3, thereby fixing the protective cover 3. This changes the traditional bolt fixing method and is more efficient.
