[0001] The utility model belongs to the technical field of pump bodies, and particularly relates to an anti-oil leakage structure for a chemical pump body. Background Art

[0002] The pump body consists of two major parts: a water suction chamber and a water pressure chamber. At the inlet of the water suction chamber and the outlet of the water pressure chamber are the water pump inlet flange and the outlet flange respectively, which are used to connect the inlet pipe and the outlet pipe. The water suction chamber is generally a tapered short pipe that gradually narrows or a straight pipe with a constant diameter. Its function is to introduce the oil liquid into the impeller and provide the required flow pattern for the impeller. The function of the water pressure chamber is to collect the liquid flowing out of the impeller and direct the liquid flow to the outlet. The shape of the water pressure chamber is very similar to a snail shell, commonly known as a volute. The impeller is wrapped in the volute. Usually, a bearing seat is arranged inside the pump body, which is convenient for installing the bearing and can also supply oil for lubricating the bearing. Since the lubricating oil has fluidity, oil leakage is likely to occur during the operation of the equipment. Content of the Utility Model

Since the lubricating oil has fluidity, oil leakage is likely to occur during the operation of the equipment.

[0004] The technical solution of the utility model is as follows: an anti-oil leakage structure for a chemical pump body, including a bearing seat. An installation groove is opened inside the bearing seat. The bearing seat is fixedly connected with the outer ring of the bearing through the installation groove. An inner ring of the bearing is arranged inside the outer ring of the bearing. A clamping groove is opened inside the bearing seat. A baffle is arranged inside the clamping groove. A diversion plate is fixedly connected to the top of the baffle. The outer wall of the diversion plate is inclined all around. A communication groove is opened at the bottom of the inner wall of the clamping groove. The bottom of the bearing seat is connected with the top of a collection box. The collection box is communicated with the clamping groove through the communication groove.

[0005] As a further solution of the utility model: a first sealing ring is fixedly connected inside the outer ring of the bearing, and the outer wall of the first sealing ring is connected with the outer wall of the inner ring of the bearing.

[0006] As a further solution of the utility model: a second sealing ring is fixedly connected to the inner wall of the bearing seat, and the outer wall of the second sealing ring is connected with the outer wall of the inner ring of the bearing.

[0007] As a further solution of the utility model: a cavity is opened inside the outer ring of the bearing. The outer ring of the bearing is communicated with an oil injection pipe through the cavity. The oil injection pipe passes through the bearing seat and extends to the outside of the bearing seat.

[0008] As a further solution of the utility model: a thread groove is provided on the outer wall of the injection oil pipe, and the injection oil pipe is threadedly connected with the sealing cover through the thread groove.

[0009] As a further solution of the utility model: mounting holes are provided at the four corners of the bearing seat, four mounting plates are fixedly connected to the outer wall of the collection box, the positions of the mounting plates correspond to the positions of the mounting holes, and a filter membrane is fixedly connected to the inner wall of the communication groove.

[0011] As a further solution of the utility model: trays are fixedly connected to the outer walls of the damping sleeve and the damping rod, and one side where the two trays face each other is fixedly connected to both ends of the same shock-absorbing spring.

[0012] The working principle and beneficial effects of the utility model are as follows:

[0013] For this anti-oil leakage structure of the chemical pump body, by setting the clamping groove, baffle, diversion plate, communication groove and collection box, during use, if lubricating oil leaks, the lubricating oil will drip onto the diversion plate. Since the diversion plate is a slope and the surrounding is arc-shaped, the lubricating oil will flow into the communication groove through the diversion plate, and then flow into the collection box through the communication groove, so that this anti-oil leakage structure can prevent the lubricating oil from leaking from the bearing seat into the pump body, thereby avoiding the influence of the lubricating oil on the normal operation of the pump body, and can collect the leaked lubricating oil, thus reducing the waste of resources.

[0014] For this anti-oil leakage structure of the chemical pump body, by setting the damping sleeve, damping rod, tray and shock-absorbing spring, when the bearing seat vibrates, an external object will squeeze the damping rod, causing the damping rod to move along the damping sleeve and drive the tray connected to the damping rod to move, thereby squeezing the shock-absorbing spring. Since the damping sleeve contains a damping medium, the elastic force of the shock-absorbing spring during rebound will offset the resistance of the damping rod moving out, thus achieving the shock-absorbing effect, so that this anti-oil leakage structure can play a shock-absorbing effect on the bearing seat during use, thereby avoiding the situation that the internal lubricating oil leaks rapidly due to rapid vibration during the use of the bearing seat, and further ensuring the stability of this anti-oil leakage structure.

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the scope of protection of the present utility model.

[0023] Such as Figures 1-5As shown in the figure, the present utility model provides a technical solution: an anti-oil leakage structure for a chemical pump body, including a bearing housing 1. An installation groove is provided inside the bearing housing 1, and the bearing housing 1 is fixedly connected to the outer bearing ring 2 through the installation groove. An inner bearing ring 3 is arranged inside the outer bearing ring 2. A clamping groove 4 is provided inside the bearing housing 1, and a baffle 5 is arranged inside the clamping groove 4. A diversion plate 6 is fixedly connected to the top of the baffle 5. The outer wall of the diversion plate 6 is inclined all around. A communication groove 7 is provided at the bottom of the inner wall of the clamping groove 4. The bottom of the bearing housing 1 is connected to the top of the collection box 8, and the collection box 8 is communicated with the clamping groove 4 through the communication groove 7. A first sealing ring 9 is fixedly connected inside the outer bearing ring 2, and the outer wall of the first sealing ring 9 is connected to the outer wall of the inner bearing ring 3. By setting the first sealing ring 9, the sealing performance between the outer bearing ring 2 and the inner bearing ring 3 can be improved, thereby reducing the volume of lubricating oil leakage. A second sealing ring 10 is fixedly connected to the inner wall of the bearing housing 1, and the outer wall of the second sealing ring 10 is connected to the outer wall of the inner bearing ring 3. A cavity is provided inside the outer bearing ring 2, and the outer bearing ring 2 is communicated with an oil injection pipe 11 through the cavity. The oil injection pipe 11 passes through the bearing housing 1 and extends to the outside of the bearing housing 1. Thread grooves are provided on the outer wall of the oil injection pipe 11, and the oil injection pipe 11 is threadedly connected to a sealing cover 12 through the thread grooves. By setting the sealing cover 12, the oil injection pipe 11 can be sealed to prevent external dust and sundries from entering the outer bearing ring 2 through the oil injection pipe 11 and causing pollution and damage. Installation holes 13 are provided at the four corners of the bearing housing 1. Four mounting plates 14 are fixedly connected to the outer wall of the collection box 8, and the positions of the mounting plates 14 correspond to the positions of the installation holes 13. A filter membrane 15 is fixedly connected to the inner wall of the communication groove 7. By setting the filter membrane 15, impurities in the lubricating oil can be filtered. Two placement grooves are provided on the outer wall of the bearing housing 1, and the bearing housing 1 is fixedly connected to one end of a damping sleeve 16 through the placement grooves. A damping medium is filled inside the damping sleeve 16. A damping rod 17 is movably connected to the inner wall of the damping sleeve 16. Tray 18 is fixedly connected to the outer wall of the damping sleeve 16 and the outer wall of the damping rod 17, and the opposite sides of the two trays 18 are fixedly connected to both ends of the same shock-absorbing spring 19. By setting the damping sleeve 16, the damping rod 17, the tray 18 and the shock-absorbing spring 19, when the bearing housing 1 vibrates, an external object will squeeze the damping rod 17, causing the damping rod 17 to move along the damping sleeve 16 and driving the tray 18 connected to the damping rod 17 to move, thereby squeezing the shock-absorbing spring 19. Since the damping sleeve 16 contains a damping medium, the elastic force of the shock-absorbing spring 19 during rebound will offset the resistance of the damping rod 17 moving out, thereby achieving the effect of shock absorption, enabling the anti-oil leakage structure to have a shock-absorbing effect on the bearing housing 1 during use, and further avoiding the situation of rapid leakage of internal lubricating oil due to rapid vibration during the use of the bearing housing 1, and further ensuring the stability of the anti-oil leakage structure.

[0024] The working principle of the present utility model is as follows:

[0025] During use, unscrew the sealing cap 12, and then inject lubricating oil into the inner part of the outer bearing ring 2 through the oil injection pipe 11, so as to lubricate the cage and the inner bearing ring 3 inside the outer bearing ring 2. During the rotation of the inner bearing ring 3, if lubricating oil leaks, the lubricating oil will drip onto the deflector 6. Since the deflector 6 is a slope and the periphery is arc-shaped, the lubricating oil will flow into the connecting groove 7 through the deflector 6, and then flow into the collection box 8 through the connecting groove 7 and the filter membrane 15. When the bearing housing 1 vibrates, an external object will squeeze the damping rod 17, causing the damping rod 17 to move along the damping sleeve 16 and drive the tray 18 connected to the damping rod 17 to move, thereby squeezing the shock-absorbing spring 19. Since the damping sleeve 16 contains a damping medium, the elastic force of the shock-absorbing spring 19 rebounding will offset the resistance of the damping rod 17 moving out, so as to achieve the shock-absorbing effect.

[0026] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
