Air cooler manufacturers: installation and separation of air coolers and selection
For proper installation, it is recommended to use hoses, properly install bypass and unload loops, or use independent circulation cooling. The air cooler must be placed in a well-ventilated place, and it is easy to bruise the dirt of the air entering the side, and there must be a space above the radius of the fan blade before and after to facilitate the air circulation and heat exchange effect. In order to protect the air cooler from rupture, when the air cooler is installed in the oil return loop, it is necessary to install a by-pass unloading circuit, which is in parallel with the cooler, and confirm that when the pressure relief encounters convex waves, it can be preferentially open for unloading. Clean the air side, you can use compressed air or hot water, along the direction of the aluminum sheet to clean, please note that the power must be off, and protect the fan coil from water.

The air cooler manufacturer is a machine equipment that uses gas as a heat exchanger to carry out heat exchange, and heat is brought according to the gas. The key to the actual effect of heat removal lies in the total heat transfer area and exhaust air volume of its component heat pipe radiator. The same total heat transfer area, the greater the exhaust air volume, the better the actual effect of heat removal. Its installation parts and natural ventilation problems in the whole process of use must be fully considered, then how to layout explosion-proof air cooler can make it give full play to the best practical results?

Air cooler manufacturers: Reference items and common problems of air coolers
Air-cooled cooler as a limited pressure vessel for hydraulic system heat dissipation, its function is of course heat dissipation, so the size of the heat dissipation capacity is an important indicator of its functionality, just like the parameters of the number of household air conditioners, determine the use effect; There is also an important parameter is the metal strength, for the cooler, these two are very necessary reference terms.
When the hydraulic system of Hannan hydraulic station is working, the foam caused by gear oil seriously harms the dynamic model of the price of small hydraulic station, and is likely to cause volume modulus changes, resulting in cavitation, noise, oil dissolution, water temperature rise, oil deterioration and a series of problems.

History of Hydraulic Technology
On-site diagnosis requires that maintenance personnel have certain knowledge and practical experience of hydraulic transmission. Before diagnosing the failure of a new model, we must carefully read the random operation and maintenance instructions to have a basic understanding of the machine's hydraulic system. By reading the technical data, master the main parameters of the system; familiar with the schematic diagram of the system, master the functions and mutual relations of the symbols of the components in the system, and analyze the function of each branch circuit; the structure and working principle of each hydraulic component should also be Have an understanding; analyze the possible causes of a certain failure; compare the position of each hydraulic component with the machine and the connection between them. When specifically diagnosing a fault, you should follow the sequence of "outside to inside, first and then difficult", and investigate the possible causes of a certain fault one by one.
