I. Conditions of use

Similar to GLLQ tubular cooler, the product is suitable for hydraulic and process lubricating devices in industrial sectors such as metallurgy, mining, light industry, power, chemical industry, etc., to cool the hot working oil to the required temperature; the designed high temperature of the cooler is 100 ℃ ～ 120 ℃, working pressure ≤1.6MP a, heat transfer coefficient is 348 ～ 407w / m2.k, (if using finned tube heat transfer, the heat transfer coefficient is 523 ～ 580W / m2 · k, but medium is allowed The viscosity is 10 to 50 c S t). The L Q type cooler listed below specifies the medium viscosity as 10 ～ 326cSt. The main technical parameters are as follows:
