(Denmark steering power cylinder,produced by Hebei Hengyu company)

steering power cylinder are widely used in Denmark,because of simple structure and reliable operation,excellent temperature resistance,no transmission clearance.So our company has designed steering power cylinder for customers from Denmark.

Introduction to steering power cylinder:

steering power cylinder piston rod material selection and technical requirements: (I), because there is no special requirements, so use 45 steel as the piston rod material, the design of the piston rod only withstand pressure stress, so no modulation processing; (ii) The coaxial tolerance of the shaft journal and the outer circle of the mounting piston is not greater than 0.01mm, so as to ensure the coaxial degree of the outer circle of the piston rod and the outer circle of the piston, and avoid the stuck phenomenon of the piston and the steering power cylinder, the piston rod and the guide. The vertical tolerance between the end face of the mounting piston and the axis of the piston rod is not more than 0.04mm/100mm to ensure that the piston installation does not produce skew; (iii) The outer circle of the piston rod should pay attention to the roughness; (iv) Because it is operated under low load conditions, surface treatment is omitted.

In the process of using the steering power cylinder, sometimes such a problem will occur, the steering power cylinder can not act immediately after the instruction of the steering power cylinder action is issued, and it must be moved after a short time, or sometimes it can move and stop moving, showing that the operation is very irregular. The cause and elimination of this failure mainly include air in the oil steering power cylinder. Elimination method: exhaust through the exhaust valve. Check the piston rod reciprocating parts of the sealing ring for air inhalation, if so, replace the sealing ring.

Do not regularly check the damage of the chrome layer of the steering power cylinder: completely extend the steering power cylinder and carefully check whether there is any surface damage such as injury, strain, welding slag, such as the surface damage position, in the steering power cylinder block < 20cm, and the damage depth < 5mm, should be repaired in time to prevent long-term damage to the steering power cylinder seal. Welding slag is strictly prohibited on the surface of the steering power cylinder.

When installing the steering power cylinder, the axial ends of the steering power cylinder cannot be fixed. Due to the effect of liquid pressure and thermal expansion in the steering power cylinder, there is axial expansion. If the two ends of the steering power cylinder are fixed, all parts of the steering power cylinder will be deformed. When disassembling the steering power cylinder, it is strictly forbidden to hammer the steering power cylinder and the piston surface, such as the steering power cylinder hole and the piston surface is damaged, do not allow sandpaper grinding, to use a fine oil stone carefully grinding. The clearance between the guide sleeve and the piston rod should meet the requirements.

Answers to some questions about steering power cylinder:

When the cylinder is tested, why can't the pressure be maintained with the balance valve?
Because the oil into the oil chamber through the hydraulic lock on the control oil circuit through the other side of the spool, the original valve is designed in this way. It locks the circuit after the oil supply circuit loses pressure, on the contrary, if you keep supplying pressure, it is always in the state of opening the other side of the one-way spool. So this valve can't be used in the test.

Hydraulic cylinder application areas?
1, in the machine tool industry, 85% of the machine tool transmission system adopts hydraulic transmission and control. Such as grinding machine, milling machine, planer, broaching machine, press, shearing machine, and combined machine tools. 2, in the metallurgical industry, electric furnace control system, rolling mill control system, open furnace charging, converter control, blast furnace control, strip deviation and constant tension device are all using hydraulic cylinders. 3, in the construction machinery, the general use of hydraulic transmission, such as excavators, tire loaders, truck cranes, crawler bulldozers, tire cranes, self-propelled scrapers, graders and vibration rollers. 4, in agricultural machinery, the use of hydraulic cylinders is also widely used, such as combine harvesters, tractors and so on.
