Vertical injection molding machine hydraulic part of the cause of the problem

Vertical injection molding machine hydraulic parts fault what reason is caused? Then we will introduce for you. ( A) : : (hydraulic oil pollution 1) : oil mixed with air. Pipe fittings, mainly due to the hydraulic pump, hydraulic cylinder, etc is bad. Performance has bubbles on the fuel tank. ( 2) : oil mixed with water. Can make the oil into a milky white. The main reason for the cooler leaking or humid environment. ( 3) : oil mixed with solid impurities. Is the main chip, welding slag, rust and metal powder. ( 4) : the oil produced in colloid substances. Main feast or erosion was the oil seal oil metamorphism, produce colloidal substances in the oil, the colloid matter often make pore clogging. ( 2) : what is the effect of temperature on the viscosity of hydraulic oil, the effects of: 1) : when the temperature rises, the oil viscosity decreased. The oil viscosity changes directly affect the performance of hydraulic system and leakage. ( Normal temperature between 30 ~ 50 ℃) ( 3) : creep failure reasons: ( 1) : bad lubrication conditions. A & other; Pause & ndash; Taxi & ndash; Pause & throughout; 。 Increase the amount of lubrication. ( 2) : in air in the hydraulic system. Need to vent. ( 3) Reason: mechanical rigidity. Change parts wear deformation, cause friction and produce crawling. Replacement parts. ( 4) : the boot production after a period of time, oil pump. Methods: 1) : suction tubing quality is bad or throat tightened. Check whether the deformation split screen. If the suction tubing stratification. Replace the tubing, mesh. ( 2) : the mesh isn't clean. The hydraulic oil impurity is too much. Clean strainer. ( 3) Oil pump wear: check the oil pump oil distribution disc and abrasion of rotor end face. Replace the oil pump. ( 5) : after the motor starting, gauge pressure, there is no traffic. Methods: 1) DA board: DA board, bad maintenance. ( 2) : overflow valve sticking. Remove the relief valve inspection, cleaning the overflow valve or replace the pressure gauge to check. ( 6) No pressure flow (: 1) : check the oil pump motor rotation direction is normal. ( 2) : check whether the oil. ( 3) : look for current pressure flow valve. ( 4) : is there a socket head pressure valve core whether pressure, replacing or cleaning.
