The basic principle of all kinds of vacuum pump

2023-07-20

1. Overview A vacuum pump is a device that uses various methods to create, improve and maintain a vacuum in a closed space. A vacuum pump can be defined as a device or equipment that uses mechanical, physical, chemical or physical-chemical methods to pump a container to obtain a vacuum. With the development of vacuum applications, the types of vacuum pumps have developed many kinds, and their pumping speeds have risen from a few tenths of a second to hundreds of thousands or millions of liters per second. The ultimate pressure (ultimate vacuum) ranges from coarse vacuum to extremely high vacuum above 10-12Pa.

Oil-free screw vacuum pump: really do not need to add any lubricating oil?

Oil-free screw vacuum pump: really do not need to add any lubricating oil?

2023-07-20

Oil-free screw vacuum pumps: maybe don't have to add all the anti-rust oil? First, with the continuous progress of science and technology, a variety of new equipment has been widely used in all walks of life. In addition, Jiangsu oil-free screw vacuum pump as an efficient, energy-saving, environmentally friendly vacuum pump, has been more and more sought after by enterprises. However, many people have doubts about whether Jiangsu oil-free screw vacuum pumps may not have to add all anti-rust oil. This version will be discussed. Second, we need to understand the basic principles and structure of Jiangsu oil-free screw vacuum pumps. Jiangsu oil-free screw vacuum pump is a selection of oil-free anti-rust technology of vacuum pump, it through the sliding of the screw to build the vacuum degree. Its main structure includes motor, reducer, coupling, casing, screw and other components. In addition, the screw is the core component of Jiangsu oil-free screw vacuum pump, and it is also the key to build oil-free anti-rust. Third, Jiangsu oil-free screw vacuum pump is it not necessary to add all the anti-rust oil. Because Jiangsu oil-free screw vacuum pump uses oil-free anti-rust technology, it does not need to add all anti-rust oil. This can not only avoid environmental pollution caused by anti-rust oil pollution, but also reduce the cost of protection and maintenance time. Fourth, it should be noted that although the Jiangsu oil-free screw vacuum pump does not need to add all the anti-rust oil, but the working environment still needs to be kept clean and moist. If the working environment is widespread dust, grease and other impurities, it will affect the normal work of Jiangsu oil-free screw vacuum pump, and even cause damage. Fifth, Jiangsu oil-free screw vacuum pump in the use of the process also need to follow how many operating procedures. For example, it is necessary to check whether the pump body and pipeline are leaking before use. During use, it is necessary to avoid long-term and short-term operation. After stopping use, the pump body and pipelines should be wiped as soon as possible. The compliance of these operating procedures can guarantee the normal service life and working efficiency of Jiangsu oil-free screw vacuum pump. In general, Jiangsu oil-free screw vacuum pump does not need to add all anti-rust oil, but the working environment needs to be kept clean and moist, and how many operating procedures need to be followed at the same time. Only in the correct use and maintenance, must give full play to the advantages of Jiangsu oil-free screw vacuum pump, for the enterprise to bring less benefits and value.

During the use of the oil-free screw vacuum pump, attention should be paid to inspection, operation and regular maintenance to ensure that the oil-free screw vacuum pump can work normally. 1. jiangsu oil-free screw vacuum pump inspection: 1. Check the screw pump, pipeline and joint for looseness. Turn the screw pump by hand to see if the screw pump is flexible. 2. Add bearing lubrication oil to the screw pump bearing body, observe the oil level should be at the center line of the oil mark, and the lubricating oil should be replaced or supplemented in time. 3. Inching screw pump motor, try to see if the motor steering is correct. 4. Regularly check the wear of the screw pump shaft sleeve, and replace it in time after the wear is large. 5. Regularly adjust the screw pump packing gland to keep the dripping in the packing room normal (preferably dripping out). 2. Jiangsu oil-free screw vacuum pump operation: 1. Unscrew the water diversion screw plug of the screw pump body, and pour the water (or slurry). 2. close the gate valve of the screw pump outlet pipe, the outlet pressure gauge and the inlet vacuum gauge. 3. Start the screw pump motor. When the screw pump is running normally, open the outlet pressure gauge and the inlet vacuum pump. After the appropriate pressure is displayed, gradually open the gate valve and check the motor load. 4. Try to control the flow and head of the screw pump within the range indicated on the sign_to keep the screw pump running at the mailbox rate point to obtain the maximum energy saving effect. 5. During the operation of the screw pump, the bearing temperature cannot exceed the ambient temperature of 35C, and the high temperature must not exceed 80C. 6. If the screw pump is found to have abnormal sound, stop immediately to check the cause. 7. When the screw pump is to be stopped, first close the gate valve and pressure gauge, and then stop the motor. 3. Jiangsu oil-free screw vacuum pump maintenance 1. screw pump in the first month of work, after 100 hours to replace the lubricating oil, after every 500 hours, oil change once. 2. When the screw pump is used in the cold winter season, after parking, it is necessary to unscrew the drain plug at the lower part of the pump body to drain the medium. Prevent frost cracking. 3. If the screw pump is stopped for a long time, it is necessary to disassemble the screw pump, wipe off the water, coat the rotating parts and joints with grease, and store them properly. Screw pump in the use of the process of the problem is a very troublesome thing, in order to better protect it, it is recommended that users understand its maintenance and maintenance, so that it can not only make it work, but also extend its use period.

How can energy-saving vacuum pumps be more energy-efficient and more efficient? This is the current technical shortcomings faced by vacuum pumps, and it is also an urgent problem to be innovated. At present, Jiangsu oil-free screw vacuum pumps mainly reduce energy consumption and improve efficiency from the use of pumps and accessories! How can vacuum pumps be more energy-efficient and more efficient? Friction work and compression work are the main power consumed by the vacuum pump. If you want to achieve energy saving and efficiency, you need to start with these two powers to reduce friction, reduce compression, and install exhaust filters to improve exhaust efficiency. Today, Filtering Brother mainly shares with you how to reduce the energy loss caused by friction and the method of reducing compression. We will discuss it in the next issue.
