Modern hydraulic system is highly integrated rapid development

Modern hydraulic system is highly integrated rapid development, particularly in the application of hydraulic manifold block and other key components, in order to meet the complex and precise design needs, extensive use of three-dimensional design of computer-aided design platform. Manifold block with steel and surface chemistry of nickel and other materials and processes mature, has a long life, corrosion protection and so on. In order to better play to its function, the arrangement must be fair position and spacing of channels, especially in the highly integrated condition will fully reflect the superiority of three-dimensional design.

Hydraulic manifold block design process

Hydraulic manifold block design process, we want to follow a design philosophy is to minimize the weight to get the manifold block are arranged to maximize and optimize system performance. In the context of rising raw material prices, the design process must be considered at the lowest cost to maximize economic benefits, of course, to save material and costs as much as possible to meet the design requirements and functional premise.
Manifold design specifications related to several aspects: including reasonable overall layout, to meet the installation requirements and piping to the equipment; note passage tunnel safety distance, to prevent cross-communication distance is too small; note installation characteristics of hydraulic components, prevent mutual interference.

Hydraulic manifold block consists of

Hydraulic manifold block consists of integrated hydraulic components (such as manifold block). When the composition of the hydraulic system with integrated hydraulic components, without additional connection block, which is connected to its own body as a body directly laminated together.
hydraulic manifold block Features:
(1) hydraulic system compact, easy to install, assemble short cycle.
(2) If the hydraulic system has changed, when changing conditions require changes in components, easily and quickly assembled.
(3) to achieve no pipe connection between the elements, eliminating leaks due to pipe, pipe joints caused by the vibration and noise.
(4) The entire system configuration flexibility, neat appearance, easy maintenance.
(5) standardization, universal and high degree of integration.

Process hydraulic valve block

Process hydraulic valve block
(1) pre-treatment process: materials processing manifold block must ensure that the internal organization of dense, not a sandwich, trachoma and other defects, prior to processing to deal with the rough inspection. Cast iron block and large block of steel processing should be carried out before the aging treatment and pretreatment.
(2) material: Usually on every side allowance of at least 2mm or more.
(3) Shape milling: Milling valve block six sides, each side stay 0.2-0.4mm margin.
(4) roughing: Roughing valve block six sides, each side stay 0.05-0.08mm refining capacity, to ensure that two pairs of parallel to the surface of less than 0.03mm, two adjacent vertical surface is less than 0.05mm.
(5) crossed: according to pattern scribe, punching the center hole (conditions can be done directly with the center drill in CNC drilling machine).
(6) Drilling: Drill the holes, surface finish roughness ra = 12.5μm. Require tapping, tapping can.
(7) tunnel boring and milling: for each well bore need be boring and milling machining.
