Before the chain bucket elevator out of factory, motor, gearbox, coupling, hydraulic coupler (some small no) and so on have been installed, but for transportation and the other reasons, after the installation of the whole machine, before commissioning must be re-measurement and adjustment, in line with the relevant requirements, and record the relevant data. General load of the chain bucket elevator is equipped with hydraulic coupler, hydraulic coupler can make the bucket has automatic protection function, once due to plugging or other reasons, the whole machine overload, hydraulic coupler can explode and play an automatic protection role. The marking and quality of the hydraulic coupler oil shall conform to the technical documentation requirements, and the liquid level of the oil shall be within the specified scale range.
The grease (oil) of the gearbox, chain and bearing shall meet the prescribed requirements. Using triangular band coupling, the tightness degree of the Triangle Belt and the straightness of the band should meet the requirements. Chain driven, chain tightness should be appropriate.
Assembly of belts and dustpan components. Belt generally take on-site hole making and assembly Dustpan, dustpan and dustpan special bolts are generally provided with the host by the supplier. Hole when the use of special belt punching for the hole, special mold as a special tool row hole, hole longitudinal, horizontal spacing according to technical documentation requirements, the size of the line spacing determines the density of the dustpan installation, thus affecting the capacity of the elevator and operation capacity. Double-row or multi-row dustpan should be installed in two adjacent dustpan to meet the maximum performance of chain bucket elevator.
After the installation of the whole machine, install the elevator speed switch, plugging switch and other electrical devices, install the on-site button, connect the remote PLC control.
During commissioning of the chain bucket elevator, the operation of the unit is checked first through the on-Site point button, the motor is lit. In the absence of abnormal conditions, can be continuous no-load commissioning, no-load commissioning time must not be less than 2 H. When commissioning, check whether the transmission parts are normal, check the vibration of the unit, noise, running deviation, there is no abnormal sound or not, at different times (0.5 h for a period of time) to check and record the temperature rise of bearings, motors and other parts, temperature rise is generally not more than 40 ℃, the maximum not more than 70 ℃. In case of condition, a decibel meter is used for noise determination, and the noise does not exceed the $ dB. After the load test is qualified after the carry load commissioning, load commissioning also check vibration, noise, running deviation, temperature rise etc, and do the running records.
