Pneumatics opportunity is unusual stop machine advocate if show blame is normal,the plan stops machine overhaul besides stop machine. Normally the circumstance falls, go to voidance press is unusual stop the reason of machine to basically have the following.

When the electric current of electric machinery overloads badly, hot relay can give out heat burned-out short circuit, make control circuit to disconnect, realize the overload protection of electromotor.
Maintain a method: 1, choose the hot relay of appropriate norms; 2, check circuit breakdown, after removing short circuit trouble, change to heat up relay suitably; 3, the change operates electromotor way, reduce number of the electromotor that start; 4, try head of take out wiring and hot relay the oxidation layer of wiring terminal, of hot relay of new impaction advocate wiring.
2, breakdown of a powerful person of discharge carry on one’s shoulder
A powerful person of carry on one’s shoulder of pneumatics machine discharge is when should changing with tolerance happening, into come through controlling a system into gas a powerful person of control valve body open degree to match to control pneumatics machine to take gas and a powerful person that do not take energy of life thereby with tolerance. If malfunction, also can cause pneumatics engine unusual stop machine. If because the card such as mechanical impurity lives,enter gas fender, after clearing clean if; of aircrew of can successful open is in into gas fender card on oriented lever, undertake to oriented lever with sand paper abrade, and in the daub on oriented lever a few grease; carry on his shoulder or back like discharge damage of a powerful person is serious, need to change a powerful person of discharge carry on one’s shoulder.
3, power source breakdown
Power source breakdown is pneumatics machine stays one of causes with the commonnest machine, also be first-rate examination and maintenance. Should check wiring of pneumatics Electromechanical source above all correct, whether did mains switch already close, in case somebody is operated by accident shut fuse of; power source whether by fusing, whether power source voltage achieves rated voltage 90% or above. Check pneumatics Electromechanical source next whether does each component have all pressure relay attaint, pressure relay set-point is appropriate.
4, exhaust temperature is high
Temperature of exhaust of screw pneumatics machine is exorbitant and average it is temperature of oily condenser and water cooler exorbitant cause, also be the reason such as sensor malfunction likely. Some call the police to be able to be eliminated instantly through controller page operation, but exhaust temperature appears to call the police exorbitantly again after be being eliminated sometimes, circulate besides the examination at this moment besides water, be about to consider the issue of lube. Medicinal powder heat is undesirable circulate with cooling system undesirable cause the main reason with exhaust high temperature namely. Radiator jams, attaint of cooling water inadequacy, water pump, likelihood is furring difference of function of too much, fan
5, nose resistance is too great
Pneumatics machine overload also can cause air switch tripping operation. Because resistance of pneumatics aircraft nose is too great,pneumatics machine overload is normally, bring about pneumatics machine to start electric current to slant big, make air switch tripping operation. Lube viscosity is too big, oily quantity overmuch or it is nose knot Jiao Dou creates pneumatics opportunity likely unusual stop machine.
Maintain a method: 1, pass artificial to pneumatics machine turning, will check nose and electric function to deny free roll, whether does obstruction increase with this judgement. Reduce when environmental temperature, oily viscosity increases, obstruction also increases subsequently, the starting electric current of electric machinery greatens, the starting time of pneumatics machine is lengthened. Can decide according to exhaust temperature the environmental temperature at that time. 2, the time that starts chance of air switch electrify is below the circumstance that assures safety make a bit lengthen, lengthen in order to what pneumatics machine starts time is satisfy when oily viscosity increases, those who will assure pneumatics opportunity is normal start. Had not lengthened please big, had lengthened congress to affect the other equipment that use phone. 3, open nose, discharge lubricating oil of the part inside nose, a powerful person has repair or change to breaking oil at the same time.
