Hydraulic cylinder manufacturers--HC news

Along with hydraulic technique's development, the hydraulic system is  wide spread in various Industry sector's application day by day. Therefore guaranteed that hydraulic system's normal movement, increases the work reliability to be important, selects the hydraulic fluid variety and viscosity correctly is the first condition for guarantee system long-term,reliable work. On the other hand, when the hydraulic system broke down, can rapid find the reason and the effective solution is also very important. The hydraulic is equipment by machinery, hydraulic pressure, electricity and measuring appliance, in order to analysis hydraulic system's breakdown must understand entire hydraulic system's transmission principle,unique feature and the part and the material disposition situation.Because the hydraulic system is sealing tape presses system, in the pipeline fat liquor mobility status, the hydraulic internal components movement and seals whether to damage is not easy to observe, therefore is difficult to analysis breakdown's reason and diagnosis's spot.
 Many reason will cause the hydraulic system breakdown, induces has three aspects:
 First, equipment's mechanical breakdown, this includes the hydraulic system design unreasonable, the installment gap is not correct, the hydraulic element quality question, the seal selects and so on improper, causes the hydraulic system breakdown by these questions not to relate generally with the hydraulic fluid.
Second, the operate miss creates the hydraulic system breakdown, because this is refers to the hydraulic system operators operates improper creates in the normal work time, like the wrong make and break valve, sudden power source stop,operating temperature or the pressure are excessively high, makes up when the oil add the wrong oil quality, fuel tank oil level have been excessively low, emits the separation not promptly from the fuel tank base the water and so on. Because the operate miss creates the hydraulic system breakdown, is not the hydraulic fluid quality question creates, does not involve the hydraulic fluid mostly, but some may reflect from the hydraulic fluid mass variation.
Third, because the hydraulic fluid quality creates the hydraulic system breakdown, this mostly because chose the improper oil or has used the unqualified oil, also possible created by long working time of hydraulic oil or long time no replace.

This article wil talk about the difference between hydraulic cylinder and pneumatic cylinder,analysis hydraulic cylinder and pneumatic cylinder advantage.one of hydraulic system,hydraulic cylinder and the pneumatic compaqration.

Introduction for hydraulic cylinder and pneumatic cylinder advantages and disadvantages,hope it wil be helpful for those who are using.
1.Generally speaking, since the pneumatic system using pressure is in 0.2 1.0 Mpa scope,so the pneumatic cylinder can not make the power of the high power component.But using hydraulic system,hydraulic cylinder can make as a large power component.
2.Consider the medium,air is inexhaustible, no cost and supply difficulties,can be used directly discharged into the atmosphere,It is convenient without pollution, but hydraulic oil is opposite.
3.Air viscosity is small, resistance is less than the hydraulic oil.
4. The air compression rate far surpass the hydraulic oil, so the stability and response aspects of working has sent far away. The hydraulic cylinder is the most important in hydraulic system of execution element, it can convert hydraulic energy to mechanical energy, and combine with all kinds of transmission agency, to finish all kinds of mechanical motion.The hydraulic cylinder advantage is simple in structure, big output, stable and reliable performance, easy operation and maintenance, wide range of application etc.

The piston make the function of seal and guidance in the hydraulic cylinder,different material also has the same piston function.HC the professional hydraulic cylinder manufacturer,also the manufacturer of piston and piston rod.
 The hydraulic cylinder is an airtight vessel, can be bearing pressure, the piston be possible to depend on the oil pour into, skids through the seal in the cylinder,thus transforms the fluid strength into the straight line or the curvilinear motion. Piston rod make form of  the movement which produces the piston transmits on the functional element, the fluid strength through enters the airtight container which from the piston and the cylinder , this kind of movement is produces depending on the liquid change in volume. The cylinder piston makes the main function of seal and guidance. Through piston rod power transmission. Its diameter different may have the different transmission ratio. Piston's function withstands the gas pressure, and passes to the connecting rod obligation crankshaft rotation through the piston pin, the piston top or combustion chamber's constituent. The working condition piston in the high temperature, the high pressure, high speed, the insufficient lubrication under the condition works. The piston with the high temperature gas contact, the instantaneous temperature may reach above directly 2500K, therefore, the heating is serious, but radiates the condition to be very also bad, therefore the piston works time the temperature is very high, the crown reaches as high as 600~700K, and the temperature distribution is very non-uniform; The piston top withstanding gas pressure is very big, specially makes the merit traveling schedule pressure to be biggest, the gasoline engine reaches as high as 3~5MPa, the diesel engine reaches as high as 6~9MPa, this causes the piston to have the impact, and withstands the lateral pressure the function; Piston in cylinder make reciprocal motion by very high speed (8~12m/s), and the speed is changing unceasingly, this makes big force of inertia, causes the piston to receive the big additional load. The piston works under this kind of bad condition, will produce distorts and accelerates to wear, will also have the additional load and the thermal load, simultaneously will receive chemical attack of the fuel gas .
