Q:Hello, which units use hydraulic pneumatic cylinders and more cylinders?. Thank you
The meter on the unit of the cylinder is big, but there is more.And the hydraulic cylinder bore is greater.
Q:What is the essential difference between hydraulic oil and lubricating oil?
Definition of hydraulic oil,Hydraulic oil pressure is the hydraulic medium used in hydraulic system with liquid pressure energy. It plays the role of energy transmission, system lubrication, corrosion prevention, rust prevention and cooling in the hydraulic system. For the hydraulic oil, should first meet the requirements of the hydraulic device in the operating temperature and the starting temperature of the liquid viscosity, the viscosity change of oil is directly related to hydraulic operation, transmission efficiency and transmission precision, but also oil viscosity temperature properties and shear stability should meet the needs of different uses of the proposed.Definition of lubricating oilLubricating oil is used in various types of machinery to reduce friction, protection of machinery and processing parts of liquid lubricants, mainly from lubrication, cooling, rust, cleaning, sealing and buffering.By contrast, some of the effects of hydraulic oils and lubricants are the same... But they differ in their environmental conditions and are higher than those for hydraulic fluids...
Q:What are the acceptance criteria for hydraulic cylinders?
China has published the hydraulic cylinder of the ISO standard (excluding seal standard 6), there are more than 20, as follows: ISO3320-75 hydraulic and pneumatic systems and components of a cylinder diameter and piston rod diameter of a ISO3321-75 metric series of hydraulic and pneumatic systems and components of a cylinder bore and piston rod diameter ISO3322-75 Inch series of hydraulic and pneumatic systems and components of a cylinder of a nominal pressure ISO4393-78 of hydraulic and pneumatic systems and components with a cylinder and a piston stroke basic pressure ISO4394-78 hydraulic and pneumatic systems and components of a cylinder diameter steel pipe processing conditions of ISO4395-78 hydraulic and pneumatic systems and components of a cylinder and a piston rod thread size ISO5597/1-80 type of hydraulic cylinder piston rod and a piston reciprocating sealing groove: Nominal dimensions and tolerances of 1 series ISO6020/1-81 -160bar series hydraulic single rod hydraulic cylinder - Mounting dimensions
Q:What are the conditions in the hydraulic system with the imported throttle valve? What is the difference between the throttle valve and the outlet valve?
1. pairs of single rod hydraulic cylinder, import throttle speed into the non rod cavity, you can get more speed than the oil back throttling speed
Q:Does the car have no cylinder pressure? Is it related to the hydraulic bottom support?
It has something to do with the tight seal of the cylinder, where the valve is hung or burned
Q:Hydraulic cylinder pressure 20 ~ 70Mpa, piston do 200 / minute 30mm stroke reciprocating action,
200 / min work frequency, high viscosity, slow flow, affect operation sensitivity.It is precisely the year that is too low to cause disclosure. Try to increase viscosity properly.This is a contradiction.
Q:The effective working area of the hydraulic cylinder is 50cm
The flow is equal to the cross sectional area multiplied by the flow velocity
Q:Why do not the industrial furnace door use the hydraulic cylinder and the cylinder?
Because the oil in the hydraulic cylinder will be heated, it will affect the oil heating, it is difficult to cool the oil heater, this is the reason, in one may be cost savings
Q:Can the cylinder be used as an internal combustion cylinder? 5
May not! The structure is about the same, but there are many differences, such as: internal combustion cylinder rings, and cylinder Oring.
Q:What are the characteristics of the cylinder compared with the hydraulic cylinder?
High speed, quick response (but less response than hydraulic cylinder)Compressed media cheapThere is no pollution problem (or pollution problems are easy to solve - for food processing and other industries which are very sensitive to pollution)
