the development of hydraulic technology

With the development of hydraulic technology, engineering machinery hydraulic drive system has been very common. From a technical point of view, any kind of hydraulic drive system should meet the reusable hydraulic hose fittings design, simple structure, easy to use, high efficiency requirements. The quality of the hydraulic system of a direct impact on the performance of the pros and cons of construction machinery, paper, hydraulic steering system uses a common Troubleshooting talk about some understanding and practices. Hydraulic steering system steering heavy one) if fast forward or turn the steering wheel are heavy and slow turn without pressure, it may be the tank level is low, the oil viscosity is too high or the valve body check valve failure. First check the viscosity of the oil tank and hydraulic oil. If the oil level is lower than the standard height of hydraulic oil is added, it should be replaced as much oil viscosity hydraulik monoblock oil viscosity is appropriate, such as the viscosity of the oil level should be decomposed normal steering. If you lose the ball check valve body into the new ball, if the ball should be cleaned of dirt stuck, if the one-way valve seal with the ball and the ball is bad impact of the application, so that reliable sealing.
