Description

Air compressor oil-air cooler parallel cooling device

technical field

The utility model relates to an improvement of a cooling water pipe of an oil-gas cooler of an air compressor, specifically changing the cooling water pipe of a serial oil-gas cooler into a parallel cooling device for the oil-gas cooler. Applicable to various forms of air compressors. the

Background technique

Air compressors have become a kind of equipment commonly used by industrial enterprises at home and abroad, and the normal operation of the air compressor is the prerequisite for ensuring the stable operation of production. There are more and more industrial enterprises using compressed air to replace the high-cost nitrogen gas. Frequent failures of air compressors will seriously affect the timely supply of compressed air and restrict the normal operation of enterprise production. Most of the air compressor failure points are caused by the high temperature of the oil-air cooler. The circulation mode of water in the cooling device is as follows: As shown in Figure 1, the cooling water first enters the oil cooler 2 from the main water inlet pipe 7 for cooling, the temperature is about 25°C, and comes out from the oil cooler 2 to the oil cooler. When the water outlet pipe 3 of the air cooler reaches 40°C, the cooled water is connected in series to the air cooler 5 from the air cooler inlet pipe 4, and finally comes out from the air cooler outlet pipe 6, and the outlet water temperature reaches 68°C or even higher. The high water temperature causes the temperature of oil and gas to rise. When the temperature of oil and gas rises to 102°C, the air compressor will automatically protect and stop. The main reason for the rise in water temperature is: the cooling water passes through the cooler for a long distance, which reduces the cooling effect and results in a higher outlet water temperature. the

Contents of the invention

The purpose of this utility model is to overcome the shortcomings of the above-mentioned prior art, and provide a new device with simple structure, convenient operation and maintenance, which can improve the operation rate of the air compressor and ensure sufficient supply of production gas.

In order to achieve the above object, the utility model adopts the following technical solutions:

A parallel cooling device for an air compressor oil-air cooler, which includes an oil cooler, an air cooler, a main water inlet pipe and a main water outlet pipe, and the oil cooler and the air cooler are connected in parallel to the main water inlet pipe and the main water outlet pipe. the

Valves are arranged on the pipelines between the oil cooler and the main water inlet pipe and the main water outlet pipe as well as between the air cooler and the main water inlet pipe and the main water outlet pipe. the

Change the cooling water pipes of the oil-air cooler from series to parallel, change the original way of cooling water in and out, shorten the circulation time of cooling water in the oil-air cooler by half, reduce the outlet water temperature of the air cooler, and thus reduce the oil-air temperature . the

The utility model has the effects of simple structure, convenient operation, obvious cooling effect, reduced downtime frequency of the air compressor, saved maintenance cost, reduced labor intensity of workers, and improved production efficiency. the

Detailed ways

Below in conjunction with accompanying drawing and embodiment the utility model is further described. the

Referring to Figure 2, the air compressor oil-air cooler parallel cooling device includes an oil cooler 2, an air cooler 5, a main water inlet pipe 7 and a main water outlet pipe 8, and the oil cooler 2 and the air cooler 5 are connected in parallel On the main water inlet pipe 7 and the main water outlet pipe 8. the

Specifically, the oil cooler 2 is respectively connected to the oil cooler inlet pipe 1 and the oil cooler outlet pipe 3, the air cooler 5 is respectively connected to the air cooler inlet pipe 4 and the air cooler outlet pipe 6, and the oil cooler inlet pipe 1 is connected to the air cooler outlet pipe 6 respectively. The main water inlet pipe 7 is connected, the oil cooler water outlet pipe 3 is connected with the main water outlet pipe 8, the air cooler water inlet pipe 4 is connected with the main water inlet pipe 7, and the air cooler water outlet pipe 6 is connected with the main water outlet pipe 8. the

Oil cooler water inlet pipe 1, oil cooler water outlet pipe 3, air cooler water inlet pipe 4 and air cooler water outlet pipe 6 are provided with valves 9, which are water inlet pipe regulating valve, water outlet pipe regulating valve, water inlet pipe regulating valve and Outlet pipe regulating valve. Compared with the prior art, the outlet pipe 3 of the oil cooler is connected to the main outlet pipe 8, and no longer enters the inlet pipe 4 of the air cooler; the inlet pipe 4 of the air cooler is connected to the main inlet pipe 7, and the inlet and outlet pipes 1, 3 of the oil-air cooler An adjusting valve 9 is set to adjust the amount of cooling water according to the cooling effect. In this way, the water intake of the two coolers becomes water with the same temperature, and the water after cooling the coolers enters the main outlet pipe 8 together, and the running distance of the cooling water in the coolers is reduced by half, and enters the oil cooler At 2 o'clock, the temperature of the cooling water is the natural water temperature of 25°C. After circulating in the oil cooler 2, the outlet water temperature rises to about 40°C. Similarly, the inlet water temperature of the air cooler 5 is also the natural water temperature of 25°C, and the outlet water temperature is also Around 40°C. After implementing the utility model, the stroke of the cooling water in the cooler is shortened, the outlet water temperature of the air cooler 5 is effectively reduced, and the normal operation of the air compressor is guaranteed. the
