Important links of vibrating screen - Erection and Test

FOR IMMEDIATE RELEASE
(Free-Press-Release.com) February 24, 2012 -- The vibrating screen installation and debugging is important for the vibrating screener users. If can influence the working life of vibratory screen and the quality of final products. So the installation and debugging played an important role in course of vibrating screen operation. So today we will talk about the vibrating screen installation and debugging in order to make the user know more about the vibrating screener working.

1) Pre-installation preparation

The new equipment, vibrating screen prior to installation, should be carefully scrutinized. As the manufacture of finished goods inventory piling up a longer time, such as rusted bearings, seals, aging or damaged during handling and so on, faced with these problems need to be replaced new parts. Also, as exciter, and the factory for rust-proof, injection of anti-rust oil, formally put into operation before the replacement into lubricating oil.

Instructions should be read carefully before installation, make full preparations.

2) The installation

(1) installation of supporting or hanging device. Installation, to foundation leveling, and then supporting or hanging device in accordance with parts drawings and installation diagram sieves, in order to install the components. Spring-loaded before the end-tag should be the actual stiffness values matching.

(2) sieve box connected to the supporting or hanging device. Bottles and later, should be required to adjust the angle. For the hanging of the sieve, it should also adjust the screen angle and screen box spindle box level. The general level of first-degree horizontal adjustment to eliminate the screen box deflection. Levels after correction, and then adjust the vertical inclination of sieve box. Vibration isolation spring force should be uniform, which could force the situation by measuring the amount of spring compression to judge. General, two sets of feed-side of the compression spring to be the same two sets of springs discharging side should also be the case. Nesting side and feed side may be differences in the amount of spring compression.

(3) installation of electric motors and the triangle tape. Installation, leveling should be based on the motor, motor level of need for correction, two tape round the corresponding grooves of the center line should coincide, triangular tension dictate the appropriate tape.

(4) required to install and fixed-screen surface.

(5) Check the connection sieve components (such as the sieve plate, exciter, etc.) a fixed situation, screen should be uniform tension, in order to prevent the generation of local vibration. Check the transmission part of the lubrication conditions, the motor and control box wiring is correct, and the rotation transmission part of the hand to see whether it is normal operation.

(6) Check the entry sieve materials, discharge chute and the funnel at work the next screen whether a crash.

3) Commissioning

Screening machine installed, commissioning should be empty, the initial check installation quality, and make the necessary adjustments.

(1) shall not be less than the sieve empty commissioning time 8h. In this time, the observation of sieve quickly whether to initiate a smooth, vibration and stability of operation, no special noise amplitude by the amplitude to observe its compliance with licensing requirements.

(2) The sieve operation, the vibrating screen box should not result in yaw. In case of yaw, which may be due both sides of the spring height difference is too large, hanging rope pull uneven rotation axis is not horizontal or triangular tape too tight, should be adjusted accordingly.

(3) driving 4h, the bearing temperature is rising, and then remained stable. The maximum temperature does not exceed 75, temperature should not exceed 40.

(4) If abnormal noise or driving after a sharp increase in bearing temperature should be immediately shut down, check whether the rotation axis is a flexible and well lubricated and so on, until after the start troubleshooting.

(5) 2-4h after driving down to check whether there are loose connection parts, if there are loose, tighten until after the drive.

(6) 8h after the test if no failure, only the installation of project acceptance.
