hydraulic machines is mainly direct drive pump

hydraulic machines is mainly direct drive pump and pump - accumulator drive two types. Such a direct drive pump drive system pumps provide high pressure working fluid to the hydraulic cylinders, with a valve for changing the flow direction for the fluid, a pressure relief valve for regulating the defined system, while the overflow from the security role. This drive system part of a small, simple structure, pressure can automatically increase or decrease in the required work force, reducing power consumption, but the biggest work force and shall be the maximum operating speed of the hydraulic machines to determine the capacity of the pump and its drive motor. This type of drive system used for small and medium sized hydraulic machine, it also directly driven pump large free forging hydraulic press. Pump - storage drive in this drive system has an accumulator or a group. When the high-pressure working fluid pump supplied with margin, store the accumulator; and when insufficient supply amount at the time of need, they supplement supplied by the accumulator. With this system you can choose according to the average amount of the high-pressure working fluid capacity of the pump and motor, but because the working fluid pressure is constant, power consumption is large, and the system of links, more complex structure. This drive system is used for large-scale hydraulic machine, or a drive system with several hydraulic press.

Acting hydraulic valve

hydraulic valve block is a pressure oil operations automation components used, which is controlled by pressure control valve pressure oil is usually used in combination with electromagnetic pressure valve can be used for remote control station oil, gas and water pipeline system off. Commonly used in clamping, control, lubrication oil passage. There are direct acting and pilot type of points, the use of pilot type.
Acting hydraulic valve manifold are used to control the flow direction of the hydraulic system in the oil or adjusting the pressure and flow, so it can be divided into directional valve, pressure valve and flow valve three categories. A shape of the same valve, can be because of the different mechanisms of action, and have different functions. Pressure valve and flow valve with a through-flow cross-section of throttling control the pressure and flow system, and directional valve replacement through the use of flow paths which control the direction of flow of oil. That is, although there are a variety of hydraulic valves of different types, among them still maintain some basic points in common.

Hydraulic components superimposed

Hydraulic components superimposed Technical Analysis 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 manifolds 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 valve superimposed manner. It is a new type of hydraulic pipe crimping  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.

Hydraulic components and systems solutions to the problem of leakage

Hydraulic components and systems solutions to the problem of leakage
There are the main method to solve the problem of leakage of hydraulic components and systems of "blocking", "lead", "anti" and "use" four ways. Blocking the way, on the site of leakage and fixed the leak is very effective, as in the leaking part coated sealant. Guided approach is mainly within the conductivity method, such as hydraulic manifold block oil block baffle plate, drain line, so that the leak oil tank. Anti-catch approach primarily designed, radical leak. Seals using both blocking, anti-two effects, so to design hydraulic power units and hydraulic systems must understand the sealing technology. For example, a gap seal of the Department, it is not necessary to use the contact seal structure. The leak is to use the method for the benefit of victims turn, is an important research topic, such as such as hydrostatic guides and bearings. Leakage from the formula and technical design perspective and field observation, the main reason for the gap caused by the leakage control issues, problems and hydraulic shock temperature heat problems, the main leak case study provides us with a specific method to solve the leakage problem.

Hydraulic system working pressure

Hydraulic system working pressure
Hydraulic system working pressure is generally 20 to 25 MPa. Troubleshooting construction hydraulic valve block at the pump shaft extension is due to wear and tear caused by leakage or emissions reduced. Whether gear pump or piston pump, 80% of its internal leakage is due to wear and tear caused by the axial sealing surface, can be solved by grinding. Failure of the hydraulic cylinder connected to the more performance for leakage or internal leakage. After being brushed hydraulic cylinder piston rod, cylinder head seals wear out quickly at the produce leakage; guide sleeve eccentric wear out of round, when it roundness error than 0.20mm will lead to leakage; seals aging also cause one reason for leakage of. In addition to replacing the seals, but also pay special attention to maintenance of the hydraulic cylinder when the amount of wear on the bearing piston ring wear is large and should be replaced. If emergency treatment, padded thin material between the support ring and the piston, the piston and cylinder in order to avoid direct contact with the cylinder caused by the pull. To avoid straining the cylinder, the support ring and the guide sleeve make the best use of non-metallic materials. By contrast the piston rod is easy to handle. If it is a large area of the nap, the cylindrical grinder can be polished rod will then hard chrome plated .05 thick. It is possible to reduce the diameter of nearly 1mm, increasing the thickness of this case can be the corresponding guide sleeve, the remainder of the cylinder head structure size even without change, will also have a good sealing effect. If you are a local or a hardened layer peeling bumps, you can use ordinary carbon steel welding rod fill the lesion.
