Hydraulic fluid quality quality, is not only interfering with engineering machinery's normal work, will create  the major damageto the hydraulic system spare part.
First, hydraulic fluid moisture content distinction   
1st, ocular estimate estimation by eye: If the fluid oil assumes the cream color opacitas shape, then in the explanation fat liquor includes the massive moisture contents.   
2nd, combustion method: With pure, the dry cotton yarn moistens the little examination the fat liquor, then lights with the fire it. If discovers the blasting open sound or the flash sign flip-flop, then in the explanation fluid oil includes many moisture contents.   
Second, hydraulic fluid foreign inclusion distinction   
1st, feeling view distinction: In the fat liquor has the obvious metal pellet suspension, twists pinches when the immediate knowledge tiny pellet existence with the finger; Under illumination, if has the reflection flash point, then the explanation hydraulic element wore seriously; If the fuel tank base precipitation has the massive sweepings, then explained that the main oil pump or the motor wore seriously.   
2nd, warming distinction: May put, in the dry test tube regarding the viscosity low hydraulic fluid to heat up the elevation of temperature purely directly. If discovered that in the test tube the fat liquor presents the precipitation or the suspension, then in the explanation fat liquor included the mechanical impurity.   
3rd, filter paper distinction: Regarding viscosity high hydraulic fluid, after available pure gasoline dilution, then uses the clean filter paper to carry on the filtration. If discovered that on the filter paper preserves the massive mechanical impurities (metal powder), then the explanation hydraulic element wore seriously.   
4: Sound distinction: If the entire hydraulic system has big, the noise and the vibration off and on, simultaneously the main oil pump sends out “humming sound” sound, even presents the connecting rod “crawling” the phenomenon, observed the fuel tank liquid level by now, the drill tubing export or the transparent liquidometer, will discover the massive froths. This kind of situation showed that the hydraulic fluid has plunged the massive air.   
Third, hydraulic fluid viscosity change distinction:   
1st, glass plate tilter: Takes a clean glass plate, its level laying aside, and will be measured that a hydraulic pressure oil dripping drop on the glass, simultaneously again drops drop of standard hydraulic fluid in side (same trademark new product hydraulic fluid), then inclines the glass plate, and pays attention to the observation: If were measured that the fat liquor the speed of flow and the flowing are away from are bigger than the standard fat liquor, then explained that its ratio of viscosities standard fat liquor is low, otherwise, then explained that its ratio of viscosities standard fat liquor is high.   
2nd, glass jar inversion law: The hydraulic pressure fat liquor which and the standard fat liquor measured distinguishes abundantly (do not install too fully) in two sizes and the length same clear-glass bottle, uses the plug to block again two bottle mouths. Two bottles lays aside abreast in row in together, then at the same time rapidly two bottles of inversions. If were measured that the hydraulic fluid rises quickly in bottle air bubble compared to the standard fat liquor's in bottle air bubble, then the showing fat liquor's ratio of viscosities standard fat liquor viscosity is low, otherwise, then the showing fat liquor ratio of viscosities standard fat liquor viscosity is high; If two kind of fat liquor air bubble rise's speed is close, then the showing viscosity is also similar

Mainly has three points:   
First, is the hydraulic machinery should maintain clean frequently,
to prevent the dust sundry goods to fall into the fat liquor, the fuel tank should cap the seal.   
Second, is in fuel tank's fat liquor should act according to the working condition regular replacement. When trades the oil,
should the contamination impurity which accumulates the fuel tank base remove, is clean the fuel tank clean.   
Third, is the hydraulic oil, the oil drum must establish in the clean security place, strengthens the management.
Uses the oil drum, the oil filter machine, the oil funnel, the drill tubing and so on should maintain clean.
The shipping hydraulic fluid's oil drum must clean beforehand cleanly,
the oil drum must special-purpose, do not be promiscuous with other oil drums.

The hydraulic cylinder spray coating  process is as follows: On the work piece  -  pre-degreasing -  degreasing - laundering - laundering phosphorizes - the laundering - hot laundering -  drying up - shield - to spurt the primer -  primer class evenly -  to spurt the finish coat -  finish coat class even - roasting to solidify - the cooling - under - examination - quality products packing -  end product warehousing (not to be unqualified returns to patching) the spray coating craft to show that the cylinder spray coating takes the quite upscale superficial painting craft method, entire process's quality requirement is extremely strict. The entire surface treatment technological process, processes, the spray coating before to have the strict quality control to the solidification, guaranteed the cylinder paints quality.   
The hydraulic cylinder spray coating craft mostly uses the multi-layered spray coating, by full display coating durability, weathering resistance good superiority. The spraying equipment must guarantee that has the splendid atomization effect, the guarantee coating uniformity, in the coating the metal particle distribution immediate influence coating outward appearance effect. Even, the quality outstanding coating has the metallic luster, the color to be bright, but uses the inappropriate spraying equipment's coating,then will produce the irregular color, the surface to have shadow or diseases and so on coating not jail .

The hydraulic cylinder mainly divides into the forklift cylinder, the engineering machinery cylinder, the automobile lifting cylinder, the special cylinder four broad headings, widely for profession production's and so on forklift, engineering machinery, automobile each kind of tonnage forklifts, the bulldozer, the car loader, the dump truck, the rock drilling drilling machine forms a complete set. And, the engineering machinery hydraulic ram's technique content is high, the market demand is big.
According to the different use, the hydraulic cylinder  has many kinds of types, according to hydraulic cylinder 's special use minute, may divide into connects the cylinder, the turbo-charged hydraulic cylinder , the speed-up hydraulic cylinder, to step-by-step the hydraulic cylinder and so on. This kind of hydraulic cylinder is not a pure cylinder tube, and other cylinder tube and the component combination becomes, therefore looked from the structure viewpoint, this kind of cylinder calls to combine the cylinder.  
According to the structural style minute, may divide into the piston hydraulic cylinder, the plunger hydraulic cylinder, the swinging hydraulic cylinder and the expansion sleeve hydraulic cylinder. According to connecting cylinder's form minute, may divide into the one-person cross talk cock stem hydraulic ram and the double-piston pole hydraulic ram.   
May divide into according to the feed direction, list function cylinder and double-acting cylinder, but affects the cylinder is only causes the piston reverse return trip toward cylinder's one side input high-pressure oil depending on other external forces. Double-acting cylinder separately to cylinder's both sides input pressure oil. Piston's forward and reverse movement depends on the hydraulic pressure to complete.

General problems of hydraulic cylinders (3)
How to prevent air from getting in the hydraulic cylinder system?
1.   Should come up to the requirements of tolerance when manufacturing and repairing parts. Assembling with fit clearance guarantee.
2.   Fasten the connections of every pipe.
3.   The seals gasket should be smooth, and not allow using multilayer paper pad.
4.   The in and out oil pipe should keep a distance, or put a clapboard to separate them.
5.   Regularly clean the oil filter and use enough capacity oil filters.
6.    The oil box should guarantee enough oil, don’t lower than oil standard instructions line.
7.    In order to ensure every parts of this system are full of oil, it is necessary to install a check valve in the pump exits and install a back pressure valve on the way of oil returning.
8.   Develop the system of hydraulic, and set a vent plug or release valve.

General problems of hydraulic cylinders (2)
The crawling resulted from the low rigidity of the drive. The air comes into the oil, some of them dissolve in oil, and the others are to be bubbles upon it. Due to the air has compressibility, it will make the hydraulic oil comes into being a obvious elasticity, and give rise to low rigidity of the drive.
Why does the air get in the oil? There must be some reasons:
1.   Under the motion of components back and forth, it needs fit clearance. So the air will get in via it easier.
2.   The hydraulic cylinder pipe connection looseness or bad sealing.
3.   Bad precision of hydraulic component.
4.   The installment of oil suction pipe is not good and suctioning the air, or blocked by dirt result in local vacuum.
5.   The oil in not enough or oil suction pipe insert shallow.
6.   Etc.
