SMC pneumatic electromagnetic valve power does not work what reason be

SMC pneumatic electromagnetic valve is fitted with no electricity for two reasons: one is the coil have burn out, the second is the electromagnetic pneumatic valve connection inside out, so when the product problems must carefully to find out the reason, targeted analysis to find out the solution.
Japan SMC pneumatic electromagnetic valve with an air inlet ( Answer the intake air, the air flow, For a target device gas source, a vent ( General installation a muffler, if afraid of noise can also not stored @ _ @. Two five-way solenoid pneumatic valve has an air inlet ( Intake air source, a positive action air flow and a reactionary to porosity ( For a target device are respectively a reverse action of gas source, a positive action vents and a reverse action vent ( The installation of muffler. For small automatic control equipment, trachea ~ mm is generally selected industrial glue
Japan SMC pneumatic electromagnetic valve is two-way flow pneumatic valve, VX is series models, behind the - Custom is a special symbol, is the general model of the pneumatic valve is not general, but a special customized models. Detail point, this kind of pneumatic valve is do for some of their clients in Japan SMC company of form a complete set of special supply, is can't buy on the market, and the general agent can't help you, even if go to the SMC company to order may also be less than, to be one and a half will not help you processing this dongdong, or charge you $ten thousand a, what do you do? Ha ha. 。 But the pneumatic valve usually is not functional change, only the dimensions is different from general pneumatic valve, distinguishing features, so you can use other to replace the same function, change the installation location is OK
SMC pneumatic electromagnetic valve power does not work is the reason why
. Different driving devices. The proportions of the SMC pneumatic valve drive is electromagnet; Motor servo pneumatic valve drive is force or torque motor;
。 Performance parameters are different. Hysteresis, in a dead zone, character such as bandwidth, filtration precision is different, so different applications, proportion servo pneumatic valve and servo SMC pneumatic valve is mainly used in closed loop control system, the structure of the other proportion of SMC pneumatic valve is mainly used in open-loop control system and the closed loop speed control system;
。 Servo pneumatic valve in a no dead zone, in the proportion of SMC pneumatic valve has a dead zone;
。 The frequency response of the servo pneumatic valve ( Higher response frequency, can be as high as about Hz, the proportion of SMC pneumatic valve is generally highest dozens of Hz;
。 Servo pneumatic valve of hydraulic oil demand higher, need to be filtered to just go, otherwise easy to jam, low proportion of SMC pneumatic valve requirements;
。 Pneumatic valve core structure and machining accuracy are different. Proportion of SMC pneumatic valve adopts pneumatic valve core + pneumatic valve body structure, pneumatic valve and a pneumatic valve sleeve. Proportion servo pneumatic valve and servo SMC pneumatic valve adopts pneumatic valve core + the structure of the pneumatic valve set.
。 The median function of different kinds. Proportional reversing pneumatic valve is similar to ordinary reversing pneumatic valve of a function, and the servo pneumatic valve function only O ( E Rexroth products.
。 Rating of the pneumatic valve pressure drop is different.
the proportions of the Japan SMC pneumatic valve principle using SMC pneumatic servo pneumatic valve or valve is: the purpose of the electric control way of flow throttle control ( , of course, after a change on the structure can also be used to realize pressure control, etc. , since it is throttle control, is bound to have energy loss, pneumatic valve and other pneumatic servo valve, its energy loss bigger, because it needs certain flow to maintain the prestage control oil circuit work.

proportion of Japan SMC pneumatic valve slide pneumatic valve structure difference extension information
the Lord of the servo pneumatic valve pneumatic valve in general and the reversing as sliding structure of pneumatic valve, pneumatic valve pneumatic valve core of the reversing not only by electromagnet push, but by pneumatic valve prestage output liquid pressure to drive, this point and electro-hydraulic reversing pneumatic valve is similar, but the electro-hydraulic reversing pneumatic valve prestage pneumatic valve is pneumatic valves, solenoid directional pneumatic valve prestage of pneumatic servo valve is the dynamic characteristics of a good aerodynamic nozzle flapper valve or jet pipe pneumatic valve.
that is to say, the Lord of the servo pneumatic valve pneumatic valve is to rely on prestage of pneumatic valve to control the output pressure, the pressure of the pneumatic valve prestage comes from the entrance of the servo pneumatic valve p, pressure is not enough, if p at the mouth of the pneumatic valve prestage cannot output enough pressure to push the main pneumatic valve core movement.
