Selection and maintenance of flange loose sleeve expansion joint

Generally speaking, a good one Expansion joint It can be as follows:

1. The material used for the appearance of flange type loose sleeve expansion joint: there are two types of stainless steel: spray painted and stainless steel, and the model of stainless steel is also different. Now 304 steel is used well on the expansion joint.

The difference between the electrical appliance flange and the expansion joint is not easy.

3. The rationality of the link design of each part of the flange loose sleeve expansion joint and the fine degree of installation have certain influence on a good expansion joint.

4. The quality of the flange type loose sleeve expansion joint vacuum pump has a certain influence. The quality of the vacuum pump will be shown only when the service environment is different and the packaging materials are different. The maintenance of the vacuum pump is also the key link, and a good vacuum pump is easy to break if it is not maintained.

If you want to prolong the service life of the flange loose sleeve expansion joint, you must pay attention to the maintenance

1. The flange loose sleeve expansion joint shall be used in the environment where the temperature is - 10 ℃ - 50 ℃, the relative humidity is not more than 85%, and there is no corrosive gas, dust and explosive danger in the surrounding air. Like the packer and shrinker, the vacuum packer has a three-phase 380V power supply.

2. It is a flange type loose sleeve expansion joint to ensure the normal operation of the vacuum pump, and the vacuum pump motor is not allowed to reverse. The oil level should be checked frequently. The normal oil level is 1 / 2-3 / 4 of the oil window (it can not be exceeded). When there is moisture in the vacuum pump or the oil color turns black, the new oil should be replaced at this time (generally, the oil should be replaced once every two months after continuous operation, and 1 × 10 vacuum gasoline or 30 × gasoline and engine oil can also be used).

3. The impurity filter should be removed and cleaned frequently (generally, it should be cleaned once every 1-2 months, and the cleaning time should be shortened if the packing of fragmented objects).

The lubricating oil should be added to the back cover for 3-4 months according to the working condition of the lubricating rod.

5. Check the pressure reducing, filtering and oil mist triple parts 24 frequently to ensure that there is oil (sewing oil) in the oil mist and oil cup, and there is no water in the filter cup.

6. The heating strip and silica gel strip should be kept clean, and no foreign matters should be stuck to avoid affecting the sealing quality.

7. The two layers of adhesive paste on the heating rod and under the heating plate play an insulating role. When it is damaged, it should be replaced in time to avoid short circuit.

8. The user should provide the working air source and the air charging air source. The working pressure of the vacuum packaging machine has been set to 0.3MPa, which is more appropriate. Do not adjust it too much without special circumstances.

9. The expansion joint is not allowed to be placed in an inclined position or impacted during the transportation, let alone put down for handling.

10. The expansion joint must be installed with reliable grounding device.

11. Do not put your hand under the heating rod to prevent injury. In case of emergency, cut off the power supply immediately.

12. When working, ventilate first and then power on; when shutting down, cut off power first and then cut off gas.

Shanghai Huanjing main products expansion joint, loose sleeve expansion joint, flange type loose sleeve expansion joint and other expansion joints. The quality of the flange type loose sleeve expansion joint vacuum pump has a certain influence. The quality of the vacuum pump will be shown with the difference of the service life and the pumping rate of the vacuum pump. The maintenance of the vacuum pump is also the main key link. A good vacuum pump is easy to break if it is not maintained.
