(Sweden steering cylinder,produced by Hengyu Group）

steering cylinder are widely used in Sweden，because of excellent temperature resistance，no transmission clearance，powerful torque.So our company has designed steering cylinder for customers from Sweden.

Introduction to steering cylinder:

Before the steering cylinder is removed, the relief valve should be loosened to reduce the pressure of the hydraulic circuit to zero, and then the power supply should be cut off to stop the hydraulic device. After loosening the oil port piping, the oil plug should be applied to plug the oil port.

The quality of the steering cylinder can not be ignored in the purchase of the steering cylinder. The steering cylinder is the main component of the steering cylinder, the single pillar for mining, the hydraulic support, the gun tube and other products, and its processing quality directly affects the life and reliability of the entire product. steering cylinder processing requirements are high, its internal surface roughness requirements are Ra0.4 ~ 0.8μm, the coaxiality, wear resistance requirements are strict. The basic feature of steering cylinder is deep hole processing, which has always troubled the processing personnel.

steering 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 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.

Classification of steering cylinder: according to the mode of movement it can be divided into linear reciprocating movement type and rotary swing type; According to the effect of liquid pressure, it can be divided into single acting type and double acting type. According to the structure, it can be divided into piston type, plunger type, multistage telescopic sleeve type, pinion and rack type, etc. According to the installation form can be divided into rod, earring, foot, hinge shaft and so on; According to the pressure grade can be divided into 16Mpa, 25Mpa, 31.5Mpa and so on.

Answers to some questions about steering cylinder:

How many tons can a 10mpa cylinder with a diameter of 100 hold up?
About 8 tons. Algorithm: Cylinder cross-sectional area = π* (100/2) ^2=3.14*2500=7850 square mm = 0.00785 square meters pressure = pressure * Cross-sectional area = 10000000Pa*0.00785 square meters = 78500 n mass = pressure /g = 78500 N ÷9.8 n/kg = 8010 kg = 8.01 Tons.

What is the function of the Reza mounted master cylinder?
The role of the Resa-mounted master cylinder is to pump the concrete from the hopper to the delivery pipe and to provide sufficient concrete outlet pressure so that the concrete can reach the specified location.
