Q:Kobelco 330 6e excavator hydraulic pump overhaul after the car is going to hold
5. low torque: the maximum torque of the engine shall not be less than 90% of the original design calibration value. The dynamometer shall be checked in accordance with the relevant provisions, and the work capacity shall be seriously damaged.
Q:How do I calculate the flow rate of the hydraulic cylinder?
Flow rate Q= speed V * hydraulic cylinder cross sectional area AWhen calculating, pay attention to the transformation of units
Q:Hydraulic principle
Hydraulic transmission is also called volume hydraulic transmission, is liquid as the medium, the transmission device to transmit energy and control the use of liquid pressure energy and kinetic energy. Usually the liquid medium using the hydraulic system with the remaining liquid pressure energy is called hydraulic oil.
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:The 80 hydraulic cylinder is equivalent to the pressure of the larger cylinder
when the hydraulic system pressure is 100kg/cm2 80mm oil output is 5 tons, the pressure when the system pressure is 5kg/cm2 then the cylinder bore 360mm can output 5 tons
Q:The difference between gas cylinder and cylinder
The cylinder control is convenient, the price is low, the energy is easy to obtain, but the force is small, and can not achieve the effect of steady speed
Q:What is the best way to repair the hydraulic rod / cylinder?
Compared with welding repair technology, the problems of local high temperature will not occur. Electroplating repair technology is the use of electrolysis principle, the bath metal ions reduced to metal atoms, and deposited on the metal surface, forming a high binding force and a certain thickness of the repair layer.
Q:Pneumatic cylinder stem can replace pneumatic hydraulic jacking rod. Who is big?
First of all, to understand your question is..:Can the top rod of the pneumatic cylinder piston rod instead of the piston rod of the hydraulic cylinder? That lever has a lot of thrust?" How is that right?Answer as followsThe top rod of a pneumatic cylinder piston rod can not replace the top rod of a hydraulic cylinder piston rod.
Q:When the 4G18 is started, the original position of the ventilation door is not put in place.
I. valve clearance: when the valve is completely closed, the gap between the end of the valve stem and the component of the valve train is called the valve clearance. Two, the valve clearance is necessary: when the engine works, the valve will be due to temperature expansion, if the valve and its transmission parts, in the cold when no gap or clearance is too small, in the hot state, and the transmission of the thermal expansion valve will cause the valve is not tightly closed, causing the engine leakage in the power stroke in compression and the power down, don't even start easily when serious. In order to eliminate this phenomenon, the valve clearance is usually used in the cold assembly of the engine to compensate for the expansion after the valve is heated. Some engines use hydraulic tappet, the length of tappet can change automatically, and the thermal expansion of the valve is compensated at any time, so there is no need to reserve the valve clearance. Three, the valve clearance is too large and too small damage, the size of the valve clearance by the engine manufacturer, according to the test to determine. Generally in cold state, the clearance of intake valve is 0.25mm~0.35mm, and the clearance of exhaust valve is 0.30mm~0.35mm. 1, too small: if the valve clearance is too small, the engine in hot state may be due to valve closed lax and leak, leading to power down, or even valve burned.
Q:The pressure system is about 200bar.
Consider 1, after the replacement function can meet the use requirements,2, after the replacement of equipment, there is still room for change.3, cost and replacement engineering difficulty4, the use and maintenance after replacement.5, environmental protection, mainly noise,
