Q:Can hydraulic oil be used instead of turbine oil?
No, VG32 turbine oil has the best effect, and several others will cause viscosity in use, which will affect the overall efficiency of pneumatic components
Q:The main difference between hydraulic circuit and pneumatic circuit
The hydraulic movement position is accurate, the barometric pressure because the compression movement is inaccurate, the hydraulic pressure general movement is slower, the barometric pressure is quicker. Hydraulic power source is generally hydraulic pump, pressure source is generally compressor. Hydraulic force is greater, the pressure is relatively small.
Q:What is pneumatic oil? Is it the same as hydraulic oil?
Pneumatic and hydraulic oils are not oils. Pneumatic lubricants require high oxidation resistance and lubricity, while hydraulic oils require good abrasion resistance, oxidation resistance, lubricity and foam resistance as well as anti emulsification effects. Pneumatic lubricants are generally thinner than hydraulic oils.
Q:Difference between cylinders of hydraulic cylinders
The working principle is very simple by using the Pascal principle (F1/A1=F2/A2), the advantages do not need lubricating oil, because his work is medium, and he can realize remote control, can realize stepless speed, no noise etc......
Q:Hydraulic cylinder pressure 20 ~ 70Mpa, piston do 200 / minute 30mm stroke reciprocating action,
High pressure and high speed will result in high temperature at the sealing place. The sealing wear and aging will be very quick, even if the trial production effect is ideal, the actual use will be a problem.Increase the surface finish and hardness of piston rodImprove the wear resistance of sealing material at high temperatureIncrease seal quantity, multi stage seal
Q:Application of hydraulic and pneumatic in industry
Hydraulic pay attention to heavy planting and stability, pneumatic attention to dexterity and speed and environment, pneumatic can be used in the pharmaceutical, food industry, each has advantages
Q:How can the hydraulic piston head and cylinder match tolerance be adjusted 20?
3, if not the special equipment, hydraulic system piston will not have high speed movement, it is by slow extrusion oil, and obtain greater impetus. But internal combustion engines are exceptional.4, the hydraulic system and the force is proportional to the size of the bore, the good solution. However, long stroke (such as ten meters) to consider the rod out of such a long deflection problem, is a key consideration.
Q:Does the hydraulic cylinder speed change with the load? Ten
How to choose the proportion of flow valve, mainly based on the flow to control the size and accuracy, pressure levels, as well as some of the owners of the special requirements of the brand.As you say 0.4L/min this small flow proportional flow valve, can choose the brand is not much, Rexroth 2FRE6 series should be able to meet your requirements. As you said, the choice of 1L/min proportional flow valve is very appropriate, in the recommended electric signal 25%~75%.
Q:How do you adjust the timing of the car's cylinder?
If there is a distributor. You can rotate around to make time earlier or later. If not, start with the timing belt, one earlier or later! To adjust the time!
Q:Can the hydraulic cylinder change the nitrogen cylinder?
Again, the cylinder is generally lighter weight, smaller cylinder, no problem, if you change the cylinder may be greater on the system requirements, in cylinder and large useless.
