1) Size:  150:  2) table Size: 150*150CM   3) bottom size:150*150CM


④    X       -- type :   none: type of standard

A: four degrees separation in the same machine (the same table)(Axis X(Y+Z),up &down &left &right)

X: six degrees separation in the same machine (the same table)(Axis XYZ ,up &down &left &right &back &forth)

G: comprehensive type

S: impact type

R: rotary type

M: manufacture type

C: swing type

⑤ P       -- computer type: none: standard/P: computer type

⑥    T       -- vibrate direction: vertical Axis Y / H: level Axis(X+Z) / T: three axis (two table)(Axis Y/(X+Z))

⑦ P       -- Frequency    : L: 50Hz power frequency / P: 0.5-600Hz / W: 0.5--3000Hz / T: 0.5-5000Hz

⑧ (150 kg) – load-bearing    : None: 100kg / direct weight



2:LongDate  Suction type electromagnetic vibration machine: Architectures, features and introductions .

①    to generate the high electric induction by using electromagnetic ring self-loop                                                                            

②   to generate the pull action by using the composite around technique                                                                                    

③ the direction of electricity to in or out are on the same circuit, and only two ports are left. According to the left hand’s law, when composite effect occurred, high excitation force happened, and then stable suction cooperation can be reached.

④  . suction type electromagnetic vibration machine’s components                                                                                     

  a: high inductance electromagnetic rings                                                                                         

  b: ultra inductance silicon steel -E/the lower one, I/the upper one, generator                         

c: spring steel (special treatment)                                                                                  

  d: brackets      

e: the base

f: surface of table

g: protective sleeve     

⑤  load-bearing and excitation will not change by the quality                                                                                        

⑥   Because of the integration of the surface of table, the base, the brackets, spring steel and electromagnetic rings, the uniform stability was enhanced to avoid the restriction of irregular items. So that we can reduce the cost of fixture. 

⑦   Modes of vibration: center horizontal line is zero; when it is vibrate from up to down, it truly meet the requirements of amplitude margin mm (p-p), to solve the problems that happen in high-frequency circular electromagnetic vibration table.

⑧  Our products can solve the problem which other high-frequency electromagnetic vibration table cannot, that the technique of vibration table is easy to influence by the circumstances of (when 50Hz/5mm/20g/less than 100kg).



3: LongDate  Suction type electromagnetic vibration machine : illustration of controlling system:

①    By using the integrated circuit module, it can get the value of frequency what is needed, through generating the frequency regulation changes.                                                

②     Various of wave types are generated: sine wave(full wave/half wave), pulse/triangle/square wave, etc.                                        

③     The controlling system is conclude by the following module:                                                                                          

a: digital panel                                                                                                                   

b: switch board                                                                                                                         

c: power control board                                                                                                                    

d: amplitude/ acceleration regulation board                                                                                   

e: various of waveform generator                                                                                                            

f: protection for overvoltage/over current/overload/stall/ PLC operation/time setting/under voltage/ overheat

 g: alarm for under load/stall/ overload                                                                                                    

h: natural air-cooled /temperature -10℃~+80℃/humidity 10%~95%                                 

i:  less than 50 decibel (less than 100 milligrams, 1 meter)      



4: The reasons why to choose the suction type electromagnetic vibration table

①     No matter what product, its performance will be adverse in a period of time because of the collision and vibration which appear during the transportation, using and retention.

②    How many companies can realize that the criticism of products can directly damage the brand of company? When the criticism appear just because the product broken for a while /seeing its end to warranty/ value is not high/ hard to find the after-sales service point.

③ When we can guarantee the quality of designing and producing process, we can foresee the invisible defects of products.

  a. Designing department: analysis the failure point, or the bad points.

  b. Quality department: analysis the different bad points from each batch.           

c. Manufacturing department: as early as possible to find out the bad points of products through measuring, when it is vibrating.

 d. Durability measurement: ensure the durability of products. The technical staff can improve the products earlier as soon as they find the design or components are not durable, so that the company’s brand can get a better reputation.
