Kenya hydraulic cylinder,steering cylinder manufacturer,steering cylinder(Kenya steering cylinder,produced by Hengyu Group)
steering cylinder are widely used in Kenya,because of clever hydraulic energy conversion,excellent temperature resistance,high work efficiency.So our company has designed steering cylinder for customers from Kenya.
When the oil pressure of the steering cylinder inlet is too low to reach the specified value, the leakage situation of the relevant oil system should be checked and the leakage should be eliminated; Check the piston and piston rod seal ring for damage, aging, loose and other phenomena; Check whether the hydraulic pump and pressure valve are faulty.
The definition of the minimum stable speed refers to the minimum movement speed of the steering cylinder without crawling phenomenon when the full load is moving, it has no uniform indicator, and the steering cylinder that undertakes different work has different requirements for the minimum stable speed.
The pressure, temperature, medium and speed of different types of seals are not the same, water-ethylene glycol medium (HFC) can not be sealed with polyurethane, it can only use rubber seal; When the steering cylinder is running fast, it must be sealed with slip ring, such as Sterseal, Glairing, GD1000K, TDI, etc., when the running speed is slow, Yx, U, V combination seals can be used; Fluorine rubber seal is used in high temperature and high pressure environment; When the running speed is fast, the buffer sleeve and buffer valve must be considered.
steering cylinder and hydraulic station selection: Select the type and structure of the steering cylinder according to the operation requirements of the main engine. According to the external load force borne by the steering cylinder, such as gravity, friction force of the external mechanism, inertia force and working load, determine the load change law of the steering cylinder in each stage of the stroke and the power value that must be provided. Determine the diameter of the piston and piston rod according to the working load of the steering cylinder and the selected oil working pressure. the flow rate of the hydraulic pump is determined according to the movement speed of the steering cylinder, the diameter of the piston and the piston rod.
What valve is used to control the speed of the cylinder?
Hydraulic cylinder for lifting is generally the piston rod downward installation, to achieve the fast and slow speed of the cylinder, you can add a two-digit three-way electromagnetic reversing valve + a throttle valve on a branch at the bottom of the cylinder, you can achieve speed change, control mode can be controlled by time control can also be controlled by stroke switch. If you want to achieve more accurate control can use proportional valve control.
Need a hydraulic cylinder, vertical upward 10 seconds to lift 20 tons of weight up 2 meters, how large cylinder and rod, how much pressure to use the plunger pump and how big?
The first thing to determine the system pressure, let's say 25 mpa, can take into account cost and performance. 1 Cylinder area 20000/250=80 square cm cylinder diameter (80/3.14) squared x2=200 mm 2 cylinder volume 80x200=16000 ml =16 L 3 Required pump flow 16x60/10=96 L/min 4 Power 96x25/55=43 kW 45 kW motor is available.
