4 Operational parameters. Life time recoendations Linde high pressure units are designed for ecellent reliability and long service life. The actual service life of a hydraulic unit is determined by numerous factors. It can be etended significantly through proper maintenance of the hydraulic system and by using highquality hydraulic fluid. Operational parameters. ressure fluids In order to ensure the functional performance and high efficiency of the hydraulic pumps the viscosity and purity of the operating fluid should meet the different operational requirements. Linde recoends using only hydraulic fluids which are confirmed by the manufacturer as suitable for use in high pressure hydraulic installations or approved by the original equipment manufacturer. Beneficial conditions for long service life >> peed lower continuous maimum speed >> Operating pressure less than 00 bar Δp on average >> Ma. pressure only at reduced displacement >> Viscosity ct >> ower continuous power or lower >> urity of fluid 8/6/ in accordance with IO 4406 or better ermitted pressure fluids >> mineral oil HL to DIN 5 54 >> biodegradable fluids in accordance with IO 5 80 on request >> other pressure fluids on request Linde offers an oil testing service in accordance with VDMA and the test apparatus required for inhouse testing. rices available on request. Adverse factors affecting service life >> peed between continuous maimum speed and intermittent maimum speed >> Operating pressure more than 00 bar Δp on average Recoended viscosity ranges ressure fluid temperature range Working viscosity range [ C] [ /s] = [ct] 0 to to 80 >> Viscosity less than 0 ct Optimum working viscosity [ /s] = [ct] 5 to 0 >> ower continuous operation close to maimum power Ma. viscosity (short time start up) [ /s] = [ct] 000 >> urity of fluid lower than 8/6/ in accordance with IO 4406 Operational parameters. Filtration In order to guarantee longterm proper function and high efficiency of the hydraulic pumps the purity of the pressure fluid must comply with the following criteria according to Linde Works tandard WN 5 0. High purity oil can etend the service time of the hydraulic system significantly. >> For reliable proper function 8/ 6/ in accordance with IO 4406 or better and long service life >>Minimum requirements 0/ 8/ 5 in accordance with IO 4406 >> Coissioning The minimum purity requirement for the hydraulic oil is based on the most sensitive system component. For coissioning we recoend a filtration in order to achieve the required purity. >> Filling and operation The required purity of the hydraulic oil must be ensured during filling or topping up. When of hydraulic systems drums, canisters or largecapacity tanks are used the oil generally has to be filtered. We recoend the implementation of suitable measures (e.g. filters) to ensure that the required minimum purity of the oil is also achieved during operation. In order to be able to select the right hydraulic fluid it is necessary to know the working temperature in the hydraulic circuit. The hydraulic fluid should be selected such that its optimum viscosity is within the working temperature range (see tables). The temperature should not eceed 90 C in any part of the system. Due to pressure and speed influences the leakage fluid temperature is always higher than the circuit temperature. lease contact Linde if the stated conditions cannot be met in special circumstances.

7 Gear pumps. Two types of gear pumps are available: internal gear pump IG and eternal gear pump EG. The possible combinations of and with IG and EG are determined by the TO option and the permitted shaft torque. Both types can be used as boost pump for the main circuit or the control and cooling circuit. The suction limit of 0.8 bar min. (absolute) must be adhered to. The boost pressure relief valves for the rated sizes 5 are integrated in the port plate housing, and for the rated sizes 0 and 80 in the charge pressure manifold of the HV0.

Controls with pressure cutoff regulation (CO) reduce pump flow when the cutoff pressure is reached. Because system pressure is maintained at low flow, the power consumption and thermal balance of the system are optimised.
