How to Check Short Circuit in Winding of the Bucket Elevator

The bucket elevator has the advantage of large conveying capacity, high lifting height and long service time. Many of us would wondering why short circuit in winding happens in the operation, this passage introduces the methods for checking the short circuit in winding in the following:

1. Check the electrical bridge;

Measure the direct-current resistance of winding. The general phase difference should not exceed 5%, if it exceeds, we can confirm that the phase with small electrical resistance has short trouble.

2. Power the elevator and do experiment;

Measure the current by ammeter, short trouble exists where there is high current.

3. Observe the surface of the bucket elevator;

Observe whether there is burn at the connecting box and the winding overhang.

4. Check the temperature of the bucket elevator;

Operate the elevator without load for 20 minutes(power it off immediately if there is any abnormal phenomenon), and touch each part of the winding part to see if the temperature is higher than the normal temperature.

5. Check by the millimeter or the Meg-ohmmeter;

Measure the insulation resistance between two any phase, if it is very low or shows no resistance, then it means there is short trouble here.

Bucket elevator conveyor system equipment

Bucket elevator is one of the most commonly used lifting equipment with the advantages of high throughput, high lift height and smooth running.When using bucket elevator,the cooperation methods between bucket elevator and upstream equipment should be noticed,please see it as follows:
a.Hand feeding: the material in the bag can be fed into the conveying equipment through the feeding port. 
Advantage:The lifting machine can run normally without material blockage.
Disadvantage: Hand feeding required higher physical strength.

b. Feeding through Bin connected with chute: the feeding method saves human cost. Loading machine and vibration hopper are allowed under available working condition, hopper can store material and also brings buffer function, which will avoid overload problem because of too much material.

c. Common feeding and conveying equipment: belt conveyor, screw conveyor, scraper conveyor and so on.
In addition,if you do not know what equipment is suitable to cooperate with the bucket elevator,please feel free to contact our engineer,we will give you a best solution: http://www.pkmachinery.com/

►Introduction

    TB Plate Chain Gravel Bucket Elevator has an opening bin below for storing material, when the motor driving the endless chain (chain or belt) through the chute, the hopper fixed in the chain of plate (chain or belt) bring the material to the discharging opening, in this way it continuously convey the material.

     It adopts plate sleeve roller chain as the traction components , gravity type discharge material. Apply to middle, big block etc grinding material, which density is less than 2t/m3. Material temperature is less than 250℃ , capacity can reach 395m3/h , lifting height is approx. 5~50m . Vertical bucket elevator are highly resistant to wear and can be placed indoor as well as outdoor.

►Working principle 
Hopper scoops up materials from the stone bucket below, then is lifted to the top with the conveyor belt or chain, and next it is downward rolled over bypass the wheel on the top and the materials are dumped into the accept slot now by bucket chain or hoist conveyor, and the whole process is over. The driving band of bucket elevator with driver is commonly made of rubber, and it is installed below or above the drive roller and the divert roller. The chain-drive bucket elevator is generally equipped with two parallel transmission chain, on which above or below is a drive sprocket and a divert sprocket. Continuous Chain or Belt Bucket Elevator for Cement are generally equipped with chassis to prevent the dust flying into the bucket elevator.

►Features
    1.Application widely, not only lifting the common powder, granular and block material, but also lifting the high grinding material;op
    2.Low driving power, low energy consumption, energy conservation;
    3.For lifting same material, energy consumption is 1/3~1/2 compared with the link chain bucket elevator;
    4.The whole machine with full sealed design, no dust pollution while running;
    5.The machine housing case adopt embossing structure, better stiffness, high precision, good-looking appearance;

►Advantage     
    1.Bucket elevator machine applys to powder, granular, lump material, the density is less than 1.5t/m3
    2.Material temperature is less than 60 ℃, if adopt heat-resistance rubber belt, the material temperature is less than 200 ℃
    3.Driven device configuration could save much space, light weight, with backstop, low noise, running steady.
    4.4 kinds bucket type could meet different particle sizes material.
    5.Customized lifting height.
