If an empty load or light load heavy steering light and heavy steering

If an empty load or light load heavy steering light and heavy steering, it may be less than the pressure relief valve block working pressure or relief valve core is stuck dirt or spring failure or damage caused by seals. First, adjust the pressure relief valve should work when adjusting invalid decomposition cleaning relief, such as spring failure, damaged seals should be replaced. 4) If you turn the steering wheel does not move when you move when the hydraulic cutting machine cylinder and the issue of irregular sound, it might be steering system with air or hydraulic steering cylinder leakage caused by too much. Should open the tank lid to see if there is a bubble in the tank, if the first check whether the leak at the suction tank, and then check the piping connections are intact, and the exclusion of air from the system. Such as hydraulic cylinders move when the time is still not moving the piston seal status should check and replace the seal if necessary.
Stacking manifold way hydraulic valve systems integration approach with a variety of specially designed according to the requirements of ordinary plate connected system stacked together, collectively referred to as the superposition of HMB integration technology. This way to integrate a hydraulic system, which can be seen superimposed valves, valve and connection block plate connected components. Superimposed valve in the hydraulic circuit block, named because of its structure and shape, as the name suggests it is a hydraulic valve can be stacked with each other, and to adapt to this integrated approach is specifically designed. Rather, stacking valve is connected to a hydraulic coupling valve superimposed manner. It is a new type of hydraulic components developed in the hydraulic valve plate connected to an integrated basis. Which itself contains from 1 to 2 separate valve, its internal structure and general hydraulic valve similar. The valve between the upper and lower surfaces of the joint surface, the valve surface in both imports and exports, respectively. In addition, there is only for internal valve connector channel. Therefore, both acts superposition of hydraulic valves, valve underway between the role of a valve in the connecting passage.
