Motor can usually vibrate in use, and reason is mainly by three kinds: reason in terms of electromagnetism；Mechanical aspects are former
Cause；The reason of electromechanics mixing aspect reason, electromagnetism aspect: in terms of 1. power supplys: imbalance of three-phase voltage, three-phase motor open-phase
Operation；2. in terms of stator: stator core variation ellipse, bias, loosening；Stator winding occur broken string, ground connection breakdown, turn-to-turn short circuit,
Wiring error, stator three-phase current unbalance；3. rotor fault: rotor core variation ellipse, bias, loosening.Rotor cage bar and end
Ring snaps, rotor cage bar fracture, coiling mistake, and brush contact is bad etc..Mechanical aspects reason: in terms of 1. motors itself: rotor
Imbalance, shaft bending, slip ring deformation, stator and rotor air gap is uneven, and stator and rotor magnetic force center is inconsistent, bearing fault, basis
Install it is bad, mechanical mechanism intensity not enough, resonance, fang bolt loosen, electric motor fan damage；2. with shaft coupling cooperation aspect:
Shaft coupling damage, shaft coupling bad connection, shaft coupling alignment is inaccurate, and load machinery is uneven, system resonance etc..Electromechanics mixing
Aspect reason: 1. motor oscillatings are often that air gap is irregular, cause unilateral electromagnet pull, and unilateral electromagnet pull makes air gap into one
Step increases, and this electromechanics immixture shows as motor oscillating；2. motor axial motion, due to rotor gravity itself or installation water
Flat and magnetic force center is not right, and caused electromagnet pull causes motor axial motion, motor oscillating is caused to increase, serious conditions
Lower generation axis grinds watt root, increases bearing bush temperature rapidly, in order to guarantee the stability of motor in use, reduce its because

It is at first plate 410, more heating motors 5 are in parallel, the electric current in 7 heating process of heating tube is increased, when reducing heating
Between, improve the producing efficiency of bottle blowing machine.
If temperature is excessively high in heating mantles 4, can inevitably bottle embryo be made to deform again, in order to guarantee the temperature in heating mantles 4
It can reasonably meet the requirements, the second inclined plate 413 positioned at two sides is equipped with radiating groove 43, and above-mentioned radiating groove 43 is inclined upwards
Shape reduces the noise in radiation processes.
The end at heating 41 both ends of cover body is equipped with heating mantles sealing plate 416, and two pieces of 416 intermediate spaces of heating mantles sealing plate are set
There is intermediate sealing plate 415, the gap between heating mantles sealing plate 416 and intermediate sealing plate 415 can be such that bottle embryo transfer tips 2 pass through just
It crosses, mounting device is mounted on outside heating mantles sealing plate 416, and feed belt 6 drives bottle embryo transfer tips 2 to pass between two gaps
It is dynamic.
In order to guarantee the stability of the heating system, 3 lower end of support column is equipped with support base 31, and above-mentioned support base 31 is in
Column and area of section are greater than above-mentioned 3 area of section of support column.
Mounting device further includes telescopic device 32, and above-mentioned telescopic device 32 is mounted on 31 top of support base, mounting device
Can by telescopic device 32 arbitrarily adjust bottle embryo transfer tips 2 position, be conducive to operator to bottle embryo transfer tips 2 into
Row replacement adjustment, telescopic device 32 can be Telescopic rod structure, and telescopic rod can be using hydraulic lifting arm, electric pushrod or similar rain
The hand push rod of umbrella structure, hydraulic lifting arm stability is higher, uses more convenient.
