Effort promotes a makings of pump processing and generation case study
From;    Author:Stand originally
1, breakdown of fan of Ci of air feed collect
1.1, value of set of pressure of relief valve of exit of Luo Ci fan slants small
Trial production initial stage, as grind those who feed makings volume to increase, pump of occurrence effort promotion is blocked up makings. Value of electric current of Luo Ci fan is controlled in 65 % , belong to normal limits, but relief valve of exit of collect Ci fan is outward exhaust. Reading of the barometer on spot conduit did not achieve relief valve to discharge pneumatics force 80kPa. Adjust afresh after lever of silk of relief valve impaction, this kind is blocked up makings can eliminate.
1.2, V-belt of Luo Ci fan falls off or burn caustic
Wear away in V-belt when ageing or new V-belt Zhang Jin do not suit, make V-belt falls off easily or burn caustic. Be like, room picture accuses to show electric current of fan of a collect Ci is worth in by normal value 70 % left and right sides falls come to carry 40 % of voltaic for nothing, and electric current of fan of additionally 2 collect Ci is controlled by 70 % rise to 80 % . Accuse in the room is right this calls the police to did not grant to notice, switch reserves collect Ci fan is not seasonable, bring about effort to promote pump to block up makings. Spot examination discovers fan of 3 collect Ci exports the relief valve on conduit all outward exhaust, the V-belt of fan of the 1st collect Ci falls off or burn down, motor racing, cause thereby additional electric current of 2 typhoons machine rises. Switch arrives reserve Luo Ci fan can solve a problem.
1.3, fan exit goes against Luo Ci stop core of a powerful person of a powerful person drops, shut-off valve a powerful person piece wear away
Exit of collect Ci fan is gone against stop the action of a powerful person is machine hind stops to prevent pressure air current to oppose change to rotor antrum in fan. Shut-off valve is pneumatic control, open before fan electromotor movement, machine hind stops to shut in electromotor, cut off those who press force air current to oppose change. Because of shut-off valve a powerful person piece wear away have gap, bring about pressure air current to oppose change from breach, concussion is gone against stop core of a powerful person of a powerful person, time grows, cause core of a powerful person to fall off. A makings appearance that this kind of reason causes as follows:
Room picture accuses to show electric current of fan of 3 collect Ci is worth the peak value instant that by normal value 70 % control to drop to carry electricity for nothing in 40 % left and right sides. Pump of promotion of spot inspection effort is blocked up makings, but relief valve of fan of 3 collect Ci not exhaust. Air current arrives from antrum of vent-pipe of malfunctioning classics of collect Ci fan, rotor outside inspiratory canal row. After stopping fan of this collect Ci, shut-off valve is shut, additional instantaneous of value of electric current of fan of 2 collect Ci rises to 80 % by 40 % , relief valve is outward exhaust.
