Household Oxygen Generator is a type of machine for producing oxygen, its principle is to use air separation technology. First, the air is compressed at a high density and then the different condensation points of each component in the air are used to separate the gas and liquid at a certain temperature, and then rectify it to separate it into oxygen and nitrogen. In general, people are used to calling it an oxygen generator because it is mostly used to produce oxygen. Because oxygen and nitrogen are widely used, oxygen generators are also widely used in the national economy. Especially Homecare Oxygen Concentrator and Household Medical Devices for hospital and household.
The first countries in the world to produce oxygen generators were Germany and France. The German Linde Company made the world's 10th m3/s oxygen generator in 1903. Following Germany, the French Air Liquide Company also began to produce oxygen generators in 1910. Since 1903, the oxygen generator has a history of 100 years.

Rotary cultivator: Select models according to local conditions
The rotary cultivator is an implement matched with a tractor, and is divided into two categories according to an auxiliary power: a walking tractor (hereinafter referred to as a hand drag) and a rotary cultivator and a wheel tractor (hereinafter referred to as wheel drag) supporting a rotary cultivator. Compared with ploughing and ploughing operations, rotary ploughing operations have the advantages of good soil properties, wide adaptability, and high operating efficiency. In the north and south of China, regardless of paddy fields and dry soils, the use of rotary cultivators is very common and occupies an important position in farming machinery. The selection of the rotary cultivator of the rotary cultivator The product model must be selected according to the local conditions, and it is determined according to the own tractor and the local natural conditions. When selecting a rotary cultivator, the user should check whether the product is qualified for inspection, reject the "three no" products and test unqualified products so as not to be deceived. Carefully check the appearance of the product, such as whether the paint is peeled off, and whether the burr is removed. It is advisable to run the empty machine for a few minutes if conditions permit, listen to the sound, check if the bearings are overheated, and if the operation is flexible. Before using the rotary cultivator, please read the safety instructions on the product manual and the machine tool carefully before use. The potential danger to the machine tool must be known, and carry out specific operations according to the main points of the manual to avoid safety accidents. Before each operation, check whether the gear box of the rotary cultivator is filled with lubricating oil, whether the bearings are filled with grease and whether the connecting bolts are fastened. If abnormal sound is found in the job, stop and check immediately to eliminate the malfunction. When walking tractors are used in combination with a rotary tractor, it is forbidden to pull and lift the machine before the machine is turned off. When the machine passes the higher field, it should turn off and pass the field. Rotary cultivator maintenance "anti-heavy governance, Yang Jin Yu Xiu" is the principle of the use of rotary cultivator. Rotary cultivator maintenance is divided into class maintenance and quarterly maintenance, under normal circumstances, each class should be carried out after class maintenance, maintenance content includes: Check the tightening bolts; 2. Check for defects such as pins, split pins and other consumables, and replace if necessary; 3. Check if the gearbox, ten bytes, and bearings are short of oil and replenish immediately if necessary. Quarterly maintenance should be carried out after completion of each quarter of the work, including (1) thorough removal of dust and grease on the equipment; (2) thorough replacement of lubricants and greases; (3) inspection of excessive blade wear and if necessary new (4) Check the hood, pallets and other deformation, restore its original shape or change the new; (5) a comprehensive inspection of the appearance of the equipment, make up the paint, machete, spline oil rust protection; (6) When not used for a long period of time, the wheel-type tractor supporting rotary cultivator shall be placed on a level ground and shall not be hung on the tractor.
