Colombia hydraulic cylinder,sanitation truck hydraulic cylinder manufacturer,sanitation truck hydraulic cylinder(Colombia sanitation truck hydraulic cylinder,produced by Hengyu Hydraulic Co., Ltd)
sanitation truck hydraulic cylinder are widely used in Colombia,because of smooth movement,high work efficiency,excellent fatigue and impact resistance.So our company has designed sanitation truck hydraulic cylinder for customers from Colombia.
sanitation truck hydraulic cylinder hydraulic oil selection: The recommended working oil viscosity of the sanitation truck hydraulic cylinder is 10 ~ 110cSt (1.8 ~ 15E), ISO VG46 hydraulic oil. The normal working oil temperature is 10 ~ 70℃, and the ambient temperature is in the range of -20 ~ 80℃. When the ambient temperature and service temperature are low, the hydraulic oil with lower viscosity can be selected.
The quality of the sanitation truck hydraulic cylinder can not be ignored in the purchase of the sanitation truck hydraulic cylinder. The sanitation truck hydraulic cylinder is the main component of the sanitation truck hydraulic 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. sanitation truck hydraulic 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 sanitation truck hydraulic cylinder is deep hole processing, which has always troubled the processing personnel.
When the sanitation truck hydraulic cylinder is installed, it is necessary to ensure that the direction of the connecting head at the top of the piston rod should be consistent with the direction of the sanitation truck hydraulic cylinder head, earring (or middle hinge shaft), and ensure the straightness of the whole piston rod during the advance and return process to prevent rigid interference and cause unnecessary damage.
Analysis of commonly used seals: The wear ring and slip ring commonly used on the sanitation truck hydraulic 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%.
How to judge the leakage in the cylinder?
Common judgment method: In the production site, people make full use of watching, listening, smelling, touching and other sensory ways, by observing that the cylinder can not move or delay the action or feel the oil temperature change, vibration and noise, etc., and then judge whether the cylinder has internal leakage according to experience. Another method commonly used in the field is to extend the cylinder in place to ensure that the cylinder does not have any load and will not retract (to prevent the cylinder from internal leakage accidents), turn off the machine, and then remove the tubing with the rod cavity, and then press the switch that pulls out the cylinder (do not press the wrong switch). If the oil nozzle with the rod cavity drains the cylinder internally, If there's no oil coming out, you have to think about something else going wrong.
Does the excavator use a hydraulic cylinder?
First, construction machinery is generally a hydraulic cylinder. Second, hydraulic transmission equipment is usually composed of four components, power, execution, control and auxiliary. And the hydraulic cylinder as a linear reciprocating motion or less than 360. Reciprocating motion of the hydraulic mechanism, simple structure, reliable work, is also widely used in the hydraulic system of the main actuator, it is the prime mover in the form of mechanical energy to drive the hydraulic pump produced by the liquid pressure energy, and then can be directly driven load for reciprocating movement or less than 360.
