The bucket elevator for cement plant manufacturer tells you that the bucket elevator is a continuous conveying machine that vertically lifts materials by using a series of hoppers that are evenly fixed on the endless traction components. The upper hopper transports bulk material upwards in a vertical or near-vertical direction. Let's take you to understand the protection points of bucket elevator for cement plant.

(1) Bucket elevator brake oil pressure overvoltage protection relay contact: When the brake oil pressure is overpressured, the oil pressure relay contact is closed, and on the other hand, a light signal is emitted, and on the other hand, it is a normally closed contact. The Ac cycle is disconnected.
(2) Leakage protection relay contact: It is used for the disconnection protection of the depth indicator automatic adjustment machine, and the car contact is disconnected when the line is disconnected.
(3) Bucket elevator power brake loss pressure relay contact: When the control power brake power supply has no voltage or the voltage is too low, the contact is disconnected.
 (4) Auxiliary contact for opening the oil cover: the bucket elevator for cement plant manufacturer tells you that when the main circuit overcurrent, fault or other reasons cause the high-voltage circuit breaker to trip, the safety brake contactor will be disconnected at the same time, and the bucket elevator will brake safely. .
(5) Bucket elevator over-roll switch contact: disconnected when the lifting container is excessively wound. One set is mounted on the derrick and the other on the depth indicator for the same purpose. In addition, the over-reset reset switch is lost, which is used to short-circuit the over-roll lift, so that the Ac circuit is opened and the safety brake is released, so that the over-wrapped container is lowered. After the container returns to the normal position, the lift should be disconnected in time, otherwise it will cause Overwind protection is invalid.
(6) The contact of the brake shoe wear switch of the bucket elevator: when the brake shoe is excessively worn, the contact is disconnected. The bucket elevator for cement plant manufacturer tells you that in addition to the protective devices installed in the safety circuit, there are some protective devices that do not require the elevator to stop immediately, which improves the cycle, but does not allow it to start again. The normally open contact of the oil pressure relay is closed if the lubricating oil is over-pressurized, the normally closed contact of the oil pressure relay is closed when the lubricating oil is under pressure, and the brake oil overheat temperature relay usually opens the contacts and so on.
