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.

water use grout plugs series

First, use
1, connecting all piping systems, tighten all threaded, connected to the gas source (or hydraulic pump), the grout plug on the orifice (or closed-end steel pipe) pressure test, check hydraulic hose assembly connections for leaks, put hole spare.
2, opening the cylinder valve or hydraulic pump, so gradually filling the expansion plug, attention must be greater than the filling pressure of air pressure to 2/3, to a predetermined pressure to grouting.
3, grouting begins, there is a lot to be back to the pulp slurry benefit out of the mouth, and then fractionated slowly pressurized to a predetermined pressure grouting, or easily form a large pressure differential. Grout should always check the gas cylinder valve pressure gauge, such as the reduction should immediately add fill.
4, filling a long time, you must check whether the channeling pulp, around the plug back plasma phenomena, if any, should stop filling, release the pressure, loosen the upper and lower inflatable plugs, inflatable plugs is to prevent the consolidation and difficult to hydraulic coupling remove.
5, the end of the grout, you must first let go of grouting pressure, inflation pressure and then let go, do not let go of the first inflation pressure to prevent grout plug injection, resulting in accidents.
6, after filling, simply plug into the filling tube closed at one end, the inflatable around 0.5Mpa, rinse cycle can be carried out.
7, grout plug after removing the hose into the plasma tube, respectively, back to the slurry pipe connection rinse.
8, together with the porous grout, all piping must be parallel to the line, and not twist and tangle together, to prevent a Fasheng security incidents affecting the other hole.
9, after prolonged use, you should plug the bottom apart for cleaning grout, on the butter.
10, drilling discovered over a hydraulic hose assemblies longer cracks or broken, it may happen channeling pulp, around the plug, return pulp, shall also put an upper end of the trachea to the grout plug, if channeling pulp, around the plug, return pulp, washed with high-pressure gas discharge, can prevent jams.
