In hydraulic power units<\/strong>, a system with a pump pushes the hydraulic oil under pressure<\/strong> inside the servomechanisms and pistons. The oil thus increase its temperature, and requires to be cooled in order to maintain its characteristics and proper operating conditions.<\/p>\n

To provide the suitable hydraulic oil cooling<\/strong><\/a> in hydraulic power plants, in Tempco we install a lot of plate heat exchangers<\/strong><\/a>.<\/p>\n

How to calculate the amount of heat to be dissipated from the hydraulic oil circuit?<\/em><\/p>\n

First of all, the hydraulic oil<\/strong> must be regulated at a suitable temperature between 40 and 50\u00b0 C<\/strong>, in order to properly feed pumps, cylinders and hydraulic motors. The thermal heat to dissipate is then calculated considering the power of the motor engine of the pump<\/strong>, that provides the circulation under pressure of the lubricating oil within the hydraulic machinery. This is indeed the element that transfers thermal power to the hydraulic oil.<\/p>\n

The exact amount is obtained by calculating the 30 or 40%, at maximum 50%, of the power of the pump’s motor<\/strong>. This will be the amount of thermal energy to be dissipated from the hydraulic oil, to cool it and maintain it at the correct temperature to preserve its functions.<\/p>\n
