hydraulic cylinder operation

This article means introduce the operation of hydraulic cylinder working. cylinder working under the eatablished pressure. takes the oil liquid as actuating medium as well as cylinder working motion. Cylinder classification with plunger type; multistage extension types; swinging type.HC professinal hydraulic cylinder maker,make you best quilty product and service.
This article means introduce the operation of hydraulic cylinder working,
1st,  hydraulic cylinde bore, the bore diameter and working pressure's determination and selects, must consider that the hydraulic system pressure source and system's pressure loss, the pressure control and the adjustment determined by the hydraulic system pressure-regulating valve.
2nd, hydraulic cylinder before work must use the low pressure (to be bigger than starting pressure) to carry on movement back forth times, after discharging the hydraulic cylinder in the air, then can carry on the normal work. Enters between the output port and the attachment must use to combine the pad to fasten, by against oil leak.
3rd,guarantee hydraulic cylinder's service life, the medium uses do not mix with the impurity, the stolen goods, in order to avoid the harm scratches in the cylinder tube, cause seal damage and hydraulic cylinder divulge. The request system filter fineness is not lower than 80μm, strict control fat liquor pollution, maintains the hydraulic fluid clean, periodic inspection hydraulic fluid's performance, and carries on the essential fine filtration or replaces the new work hydraulic fluid.
4th, recommendated to use oil's viscosity 10 ~110cSt (1.8~15E), ISO VG46 hydraulic fluid. Normal work oil temperature in 10 ~70C, ambient temperature in the - 20 ~80C scopes. When the ambient temperature and the application temperature are low, may choose the low  viscosity hydraulic fluid.
5th, the actuating medium uses when difficult to burn the water base hydraulic fluid, ordering must indicate specially alone, with the aim of replacing the special seal.
6th, guarantee the  consistent direction of rod,earring (or middle articulation axis) installs,guaranteed that the entire connecting rod's in onset and retreat process straight line, prevents the rigidity interference and  nonessential damage.
7th, hydraulic cylinder installment finished, before trying the movement, dealt with the earring, the middle articulation axis and so on relative motion spot   replenishment ubricating grease.
8th, when the hydraulic cylinder appears breakdowns divulging must disassemble, should make the piston move to the cylinder bottom, in the disassemblage refuses the rigidity strike as well as to appear falls  suddenly.
 9th, before disassemblage, make the system discharge, return route pressure zero,cut-off oil source, after loosening the oil mouth tubing, stops up the oil mouth.
10th,guarantee hydraulic cylinder's normal work, system should have the air exhaust device in design.
11th, the hydraulic cylinder should avoid not using for a long time, if due to some kind of reason long-term idle, should regular starting carry on the spatial revolution, enables its each to obtain the sufficient lubrication, in order to avoid corrosion in surface, interferes with the later normal work.
