Introduction to Simple Questions about the Setting of Diaphragm Accumulators

After setting the bladder type accumulator, check the rubber pressure once a week. After one month, check once a month. After six months, check once every six months. After one year, check once a year. Regular inspections can maintain excellent usage conditions and promptly detect leaks and repair applications.

Install a pressure gauge in front of the shut-off valve on the oil circuit connecting the accumulator inlet hole and the oil tank. Slowly open the shut-off valve to allow the pressure oil to return to the oil tank. Pay attention to the pressure gauge. The pointer of the pressure gauge slowly decreases and quickly drops to zero after reaching the pressure value. The rate of pointer movement changes to the value of air pressure. In addition, it is also possible to directly check the inflation pressure using inflation tools, but a little gas will be released every time it is checked.

The oil storage effect of energy storage devices in hydraulic systems:

Store oil and provide a large amount of system oil together with the hydraulic pump in a short period of time.

The accumulator circuit for storing oil When directional valve 5 is in the neutral position, hydraulic pump 1 charges oil to the accumulator. When the oil pressure in the diaphragm accumulator reaches a certain value, speed control valve 2 is opened to allow the pump output oil to overflow through the speed control valve. When the directional valve is located on the left or right, the accumulator of the hydraulic pump simultaneously supplies oil to the system, allowing the hydraulic cylinder to obtain a larger flow rate. Generate significant movement speed. The characteristic of this type of circuit is that the system requires a large amount of oil in the short term, and the accumulator uses the gap between the hydraulic cylinder to terminate the movement to store pressure oil, which can make reasonable use of kinetic energy A hydraulic pump with a smaller flow rate can be used in the circuit to achieve rapid movement of the hydraulic cylinder.
