1. The blocks the circuit should be as far as possible simple and to minimize the deep hole, inclined holes and technical hole.
2. For components with vertical or horizontal installation requirements, it must be designed manifold blocks according to installation requirements.
3. Manifold body dimensions, according to the form factor of the installed components, and to ensure that the block body oil duct hole minimum allowed wall thickness, and strive to compact structure, small size, light weight.
4. The block requires frequent adjustment component (such as relief valves, speed control valve, etc.), installed in a position of ease of operation and observation.
5. Manifold block is to set up a sufficient number of measurement points, in order to make debugging test of its function, pressure.
6. Manifold and external connection port, the port such as connecting the hydraulic pump oil through the tank back to the oil port, the port of the various sensors, to leave enough space to install flanges and fittings.
7. Set the lifting screw holes for the manifold blocks with weight 30kg more than.
8. To consider the rigidity and machining offset drill holes deep hole flow aperture ratio, generally no greater than 10.
9. On both sides of the deep hole drilling, the junction of cross - flow section, must not be less than which - cross sectional area of the holes.
