Burma hydraulic cylinder,clamp type cylinder manufacturer,clamp type cylinder(Burma clamp type cylinder,produced by Hengyu Group)
clamp type cylinder are widely used in Burma,because of excellent temperature resistance,no transmission clearance,powerful torque.So our company has designed clamp type cylinder for customers from Burma.
The quality of the clamp type cylinder can not be ignored in the purchase of the clamp type cylinder. The clamp type cylinder is the main component of the clamp type 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. clamp type 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 clamp type cylinder is deep hole processing, which has always troubled the processing personnel.
Protection of the clamp type cylinder surface: During the dismantling process, safety protection should be carried out on the clamp type cylinder to prevent objects from falling and welding slag from falling to the surface, causing damage to the clamp type cylinder surface. In the process of propulsion, the damaged pipe segments should be prevented from falling and smashing, and the slurry remaining on the surface of the clamp type cylinder should be cleaned up in time.
Analysis of commonly used seals: The wear ring and slip ring commonly used on the clamp type cylinder are generally made of polytetrafluoroethylene + graphite, because pure polytetrafluoroethylene is easy to produce plastic creep, which is only suitable for low pressure and low wear resistance conditions. If the sealing ring used is a composite material formed after adding graphite filler, the performance can be effectively improved, the ability to resist plastic creep is increased by 2 to 3 times, the initial deformation caused by the load is reduced by 30 to 60% : the rigidity is increased by 2 to 3 times: the dimensional stability under heat is increased by 2 times, and the hardness is increased by l0 to 15%.
clamp type cylinder head explanation: low pressure castings, medium and low pressure with HT300 gray iron, medium and high pressure with 35, 45 steel. When the clamp type cylinder head itself is the guide sleeve of the piston rod, the clamp type cylinder head is best cast iron. At the same time, brass, bronze or other wear-resistant materials should be fused on the guide surface. If the guide sleeve is pressed into the clamp type cylinder head, the guide sleeve shall be wear-resistant cast iron, bronze or brass.
How to distinguish large cavity and small cavity of excavator rod cylinder ?
Single rod piston cylinder is a form of cylinder that is used relatively most, and the boom, bucket, dozer shovel cylinder are all in this form. Among them, the rodless cavity is also called the large cavity, and the rodless cavity is also called the small cavity. Therefore, the cylinder cavity on the side with the exposed piston rod is the small cavity, and the cylinder cavity on the side without the exposed rod is the large cavity.
How to calculate cylinder pressure?
Hydraulic pressure area of cylinder × hydraulic pressure = output force of cylinder 200mm=20cm 100mm=10cm 15Mpa=150Kg/cm2 Cylinder thrust: 3.14×10×10 area ×150 pressure =47100Kg=47.1t cylinder pulling force: 3.14×(10×10-5×5) Area ×150 pressure =35325Kg=35.325t The above calculation did not consider the resistance of oil return, because you did not provide oil return pressure. But the impact should be small.
