In the use of the rubber paver machine, the maintenance of the hydraulic system can greatly reduce the failure. In general, the following points should be noted:
(1) Before adding the hydraulic oil to the hydraulic oil tank, clean containers shall be used to fill the oil. The hydraulic oil must be filtered by the oil filter before being added to the hydraulic oil tank; The replacement cycle of the hydraulic oil depends on the quality of the oil used (generally once every 1000h); Replace the hydraulic oil at the operating temperature; In order to ensure good heat dissipation of the hydraulic system, the hydraulic oil radiator should also be cleaned regularly.
(2) As the construction environment of asphalt paver is generally poor, the replacement period of hydraulic oil filter element should also be shortened (generally 750h). When replacing a new filter element, check it. It is strictly prohibited to use a deformed, polluted or rusted filter element.
(3) When starting the engine every day, it is necessary to run the engine at idle speed for a period of time before operating each actuating element, which is conducive to the use of the hydraulic pump.
(4) Due to the long-term use of the rubber paver machine, its hydraulic system parameters will sometimes change. Therefore, the parameter settings of the hydraulic system should be checked regularly and adjusted in time.
