Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of cooling methods, in particular to an externally mounted oil-injected screw air compressor radiator. Background Art
[0002] During the use of oil-injected screw air compressors (hereinafter referred to as air compressors), the air compressors often have high temperatures. There are many reasons for the high temperature of air compressors, which can be roughly divided into two parts: one is caused by component damage, in which case replacing the damaged components can solve the high temperature failure; the other is caused by the small margin of the air compressor's own cooling system, high ambient temperature at the customer site, poor ventilation, etc. In the after-sales market, the second situation occurs more frequently, and it is more difficult to solve (replacing the cooling system or renovating the air compressor station), and the cost is also relatively high. And because the cooling system has a small margin, the high temperature caused by the high ambient temperature of the customer is mostly concentrated in the summer when the temperature is high, so it is unwise to replace the cooling system or renovate the air compressor station.
[0003] In view of this situation, it is extremely necessary to develop an external radiator to improve the operating environment of the air compressor in the short term when the temperature is high, so that the air compressor can smoothly and efficiently survive the hot summer. Utility Model Content

[0006] The external circulation component is arranged on the radiator, and the oil injection component includes an oil filter, a temperature-controlled oil filter seat, a circulation oil pump and a connecting pipe. The connecting pipe is connected to the radiator, and the oil filter is fixed on the connecting pipe, and the oil filter is connected to the connecting pipe.

[0011] Compared with the prior art, the beneficial effects of the utility model are:
[0012] 1. The external oil-injected screw air compressor radiator is provided with an external circulation component, and its external circulation component is placed outside the air compressor.

If there is a description of "first" or "second", it is only used for the purpose of distinguishing the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.
[0022] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.
[0023] See also Figure 1-4 , the utility model provides a technical solution: an external oil-injected screw air compressor radiator, including a radiator 4;
[0024] The external circulation component is arranged on the radiator 4, and the oil injection component includes an oil filter 5, a temperature-controlled oil filter seat 6, a circulating oil pump 7 and a connecting pipe 8. The connecting pipe 8 is connected to the radiator 4, the oil filter 5 is fixed on the connecting pipe 8, and the oil filter 5 is connected to the connecting pipe 8.
[0025] The temperature-controlled oil filter seat 6 is fixed on the oil filter 5 , and the oil filter 5 is communicated with the temperature-controlled oil filter seat 6 .
[0026] The circulating oil pump 7 is fixed on the temperature-controlled oil filter seat 6 , and the circulating oil pump 7 is connected to the temperature-controlled oil filter seat 6 .
[0027] A mounting base 2 is welded on the surface of the radiator 4 , an air guide cover 3 is screwed on the surface of the radiator 4 , and a heat dissipation fan 1 is installed at the front end of the air guide cover 3 .
[0028] A port A is provided on the surface of the circulating oil pump 7, and the port A is the oil inlet. A port B is provided on the surface of the temperature control oil filter seat 6, and the port B is the oil return port.
[0029] Oil-injected screw air compressors generally include several major parts, including the compression system (host unit), air filter system, oil filter system, oil separation system (oil-gas barrel), cooling system, control system, etc. During the operation of the air compressor, the air compressor lubricating oil (sometimes called coolant) flows from the host unit through the pipeline to the oil inlet of the oil-gas barrel, and undergoes collision filtration and gas-liquid separation in the oil-gas barrel. The lubricating oil is deposited at the bottom of the barrel and flows from the oil outlet to the oil filter system and cooling system to participate in the next cycle.
[0030] Regarding the high temperature problem mentioned above, if it is determined that the air compressor has a small heat dissipation margin / high ambient temperature, the general solution is to increase the heat dissipation system. Limited by the customer's on-site conditions and the machine shell space, the modification is very troublesome, and because the internal pipeline of the air compressor is changed, the reliability of the air compressor is also greatly reduced.
[0031] Therefore, judging from the operation rules of the air compressor system, the cooling oil is mainly concentrated inside the oil and gas barrel. If the oil temperature inside the oil and gas barrel can be effectively reduced, the high temperature problem of the air compressor will be solved.
[0032] The oil and gas barrels of air compressors come in various forms. The most common ones generally have a refueling port and an oil drain port. The refueling port and the oil drain port are functional interfaces for air compressor maintenance and are usually blocked with a plug. Therefore, if these two holes are used to cool the lubricating oil in the oil and gas barrel, there is no need to change the internal pipelines of the air compressor, and it has a wide range of applicability.
[0033] When the utility model is working, port A (oil inlet) is connected to the oil drain port of the air compressor that needs to be cooled, and port B (oil return port) is connected to the oil filling port of the oil and gas barrel.
[0034] When the air compressor is working, the pressure of the oil filling port and the oil drain port of the oil and gas barrel is basically the same, and the oil passes through the temperature-controlled oil filter seat 6 and the oil filter 5 under the action of the circulating oil pump 7.
[0035] The function of the temperature-controlled oil filter seat 6 is to distribute the flow route of the lubricating oil. The action value of the temperature-controlled oil filter seat can be set according to the working conditions of the air compressor. When the oil temperature is higher than the set value of the temperature-controlled oil filter seat, the lubricating oil flows to the radiator 4, where it is forced to dissipate heat under the action of the cooling fan 1, and then passes through the oil filter 5 to the oil and gas barrel. When the oil temperature in the oil and gas barrel is low, the lubricating oil directly returns to the oil and gas barrel through the oil filter 5, so that the temperature of the lubricating oil is always maintained within a suitable range.
[0036] The heat dissipation of the radiator and fan can be changed to adapt to different air compressors.
[0037] The utility model is not limited by the space inside the air compressor, has a wider range of use, does not change the internal pipeline distribution, is more convenient to use, has a simple structure, and has a low cost, and is more suitable for use in the high temperature season in summer.
[0038] By setting an external circulation component and placing it on the outside of the air compressor, in the hot summer, compared with the general air compressor radiator, the radiator is set on the outside of the air compressor and will not be restricted by the inside of the air compressor. It is more convenient to change the internal pipeline distribution, which is more convenient to use, has a simple structure, and low cost, and is more suitable for the hot summer season.
[0039] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
