Hydraulic Tanks
Bladder Tank
BA15B5T01A1
Pressure: 5000 PSI
Price: $5,000.00
Gallons: 15
3256 cu in of gas
Weight: 485 lbs
power transmission:
Continuously variable drive is difficult
The relative spatial position of prime mover is fixed
If the motor is electrical (DC motor or AC motor with variable frequency), then the rotational speed can be continuously changed but they are expensive

Functional
Good lubrication characteristics
Viscosity should not depend strongly on temperature and pressure
Good heat conductivity
Low heat expansion coefficient
Large elasticity modulus
Economic
Low price
Slow aging and thermal and chemical stability long life cycle
Not inflammable fluids:
Contains water
- Does not contain water
mines, airplane production, casting, rolling, where there is explosion and fire danger
Water-oil emulsions (oil synthetic) or water-free synthetic liquids
