| Gas-liquid pressurized cylinder hydraulic system component installation points | Mechanical engineering, hydraulic components of hydraulic system is complete energy transfer of the basic components. When installed, must seriously.
1 hydraulic pipe:
(1) according to select and use oil pressure, must have enough strength of tubing inwall should be smooth, clean, and no sand, rust, no oxide skin, for long-term storage, processing of pipe should be cleaned thoroughly, flush, pickling, and checked. Key words: hydraulic and pneumatic supercharging cylinder gas-liquid supercharger
(2) with saws, section and cut out the pipe axis should not perpendicular 0.5 °, ± cutting edge shall fall and remove iron, blunt bending tube allows its processing for 10% of the ellipse section. When the outer 14mm < when usable hand and general tool steel tube bending, thicker mission with manual or mobile bend pipe bender, tube bending radius shall generally be three times larger than the pipe diameter.
(3) pipeline requirement is installed, the shortest possible route to turn, the highest part of pipeline, should establish the exhaust device, to start with a gas.
(4) to install rubber, should avoid teasers, the bending radius R acuity (9 ~ D D l0) for hose diameter). Don't bend near joint root, request to begin the bend hose connector distance L p 6D. The hose work should not be reversed.
(5), also not leak suction pipe should not be too big, prevent intake resistance or oil absorption difficult produce cavitation.
(6) back to the mouth shall fuel oil, prevent splashing oil surface bubbles produced. The relief valve and pump can return pipe directly connected to the entrance, must through the tank, otherwise, the oil temperature will be high.
(7) all piping installation procedures in two, to try assembly, pipe fittings and flange spot in the right position, when all the pipe down after changing outfits, pickling after installation official.
Two other hydraulic components
(1) all hydraulic components to pressure and seal test, qualified rear can be installed. Before installation should be all kinds of automatic control instrument calibration, avoid mistakes.
All valves installed (2), which should be paid attention to when JinYou its mouth and return the azimuth. Oil, Install valve parts with flange bolts can twist when too tight, but sometimes too tight sealed causes.
(3) installation should be strong and reliable, hydraulic cylinders to prevent thermal effects, when the schedule and high temperature, cylinder end must keep floating. The hydraulic cylinder seals don't too tight, especially the u-shaped circle, lest resistance.
(4) pump shaft motor drive shaft with no deviation should be less than the coaxial tolerance LMM 0, generally USES the flexible coupling connection, are not allowed to use tape drive pump shaft rotation, directly in case of pump shaft by radial force, the normal operation of pump.
(5) when the pump installation rotation direction and into the mouth, should comply with the technical requirements of oil. (6) of the hydraulic oil absorption height, average less than 0.5 mm.
