Correct operation and maintenance of hydraulic oil coolers

- May 17, 2018-

Hydraulic oil coolers are widely used, and their operation methods should be properly mastered. For any kind of mechanical equipment, inspection prior to start-up is indispensable, and hydraulic oil coolers are naturally not exceptional and need to be reviewed. Whether or not all of them can be connected accurately and meet the needs of the work.


Then remove the screw plug directly outside the hydraulic oil cooler outlet and close the inlet valve slowly. When the oil overflows, open the inlet valve and screw on the screw plug. Immediately afterwards, unscrew the exhaust cylinder in the hydraulic oil cooler line and close the inlet valve slowly. When the water is full, open the inlet valve and the exhaust cylinder. At this time, the water and oil are in motion. After the heat exchange, the time difference gradually becomes smaller.


When the water temperature is lowered by 5-10°C, open the icing water and the oil discharge valve, and then gradually open the inlet valve of the cooling water and oil, so that the cooling water and the oil are in active condition. Then mobilize the cooling water and flow to maintain the normal operating conditions. If it is necessary to stop the operation of the hydraulic oil cooler during operation, it is necessary to open the inlet valve for the oil and the cooling water first, and then open the discharge valve for the oil and cooling water, and then unscrew the screw plugs on the drainage and oil drain ports to discharge the product. Water and oil in the oil cooler.


As an umbrella for hydraulic systems, hydraulic oil coolers are widely used in aerospace, marine, mechanical equipment, machine tool manufacturing, automation control systems and other major industries, so in addition to the correct use of hydraulic oil coolers to ensure the long-term normal operation of mechanical equipment, it's Maintenance is equally important.


The hydraulic oil coolers should be regularly checked on the working system, especially the lubricating oil system, and replaced with new ones if necessary. At the same time, it should be cleaned regularly. After the equipment is working, it should be cleaned once every 3-6 months. Of course, the cooler must be tested periodically to see if there are any abnormalities in the parts and to ensure the normal operation of the machinery and equipment.


In addition, do not forget to carefully check the filter of the equipment on the hydraulic oil cooler during maintenance to avoid any clogging of impurities and affect the structure of the system. Also, keep the cooler working environment clean regularly and keep the outer fin of the cooler clean so as not to affect the cooling capacity.
