How to maintain the pneumatic conveying system in cold winter?

How to maintain the pneumatic conveying system in cold winter? In winter, the equipment of the pneumatic conveying system is repaired and maintained. Most of the machines and equipment of the pneumatic conveying system are installed outdoors. In cold winter, especially when the temperature is low at night and the pneumatic conveying system is shut down and does not work, if the equipment is repaired and maintained improperly, it is very easy to happen that it cannot operate normally the next day. How should we maintain the pneumatic conveying system in winter?

In winter, if you want to use the pneumatic conveying system normally, the first thing is to lubricate in time to prevent icing. Pneumatic conveying equipment needs to add a certain amount of oil to the movable bellows before operation. Its function is to lubricate the oil seals on both sides of the movable air duct. The adjusting mechanism of the reducer also needs to add an appropriate amount of oil, and the amount of fuel can be referred to the oil standard line.

The lubricating oil of pneumatic conveying equipment in winter is different from that in summer. Because the temperature is low, N46 should be used. After the initial use, the oil should be changed within one month. Generally speaking, it only needs to be replaced twice a year.

Winter maintenance, no matter what kind of machinery and equipment, as long as it is maintained, it is the best machinery and equipment, and lubrication is the best form. Therefore, in winter, it is necessary to ensure the normal operation of pneumatic conveying equipment and do a good job of lubrication.

The daily work maintenance of pneumatic conveying equipment determines whether it can be used for production smoothly. In addition to planning, manufacturing, machinery and equipment and use, the daily maintenance is also very critical. Especially when the pneumatic conveying equipment is working under the sealing condition, many mechanical failure risks are not easy to detect, which makes the importance of timely maintenance more obvious.

Pneumatic conveying
The machinery and equipment of the pneumatic conveying system can be roughly divided into: air source machinery, air duct, feeder, feeding pipe, Branch Road, separator, unloader, dust pipe, dust removal system and electric control system.

1. Maintenance of air duct

In the suction pneumatic conveying system, the air duct refers to the pipe from the back of the dust collector to the air inlet of the fan and from the air outlet of the fan to the hood. Generally speaking, the maintenance of these two parts of the pipeline is not large, but it is necessary to pay attention to the sealing condition of the joint of the air duct, and often pay attention to whether the air duct body is rusty. The destruction of the hood will lead to rainwater tank entry, and it should also be repaired in time.

In the pressure pneumatic conveying system, the stroke pipe includes the air inlet from the discharge port of the gas compressor to the feeder (or sending tank), together with the air storage tank, gas water separator, gas supply system and corresponding piping in the middle. The gas storage tank and gas-water separator belong to the pressure vessel, and their safety performance should be checked on time according to the application requirements of the pressure vessel. In addition, great attention should be paid to whether the set pressure of the safety valve is accurate. The oil and water accumulated in the gas storage tank and gas water separator should be discharged in time.

2. Maintenance of air supply machinery

In the pressure pneumatic conveying system, the air source machinery mainly refers to the air compressor and roots blower. Because it is transported by exhaust, there will be no special maintenance problems for the compressor itself. It can be repaired and maintained according to the product instructions of each manufacturer and the requirements for general machinery.

In winter, how to repair and maintain the equipment of pneumatic conveying system in cold winter? Pay attention to the equipment maintenance of pneumatic conveying equipment installed outdoors in winter, especially when it stops running at night. In the process of normal equipment maintenance, we should pay attention to the regular maintenance and inspection of the machine and equipment to see if there is any abnormal phenomenon, and pay attention to the equipment maintenance of the pneumatic conveying equipment of the air source machine and equipment, air duct, feeder, feed pipe, fork, separator, unloader, dust pipe, dust removal part, electric control system and other parts.
