What aspects should be paid attention to when using the dredger?
2022-08-18
In recent years, dredgers have been widely used in the dredging of ports and ship channels, and the work of new construction and expansion. It can be seen that dredgers have become an indispensable part of the field of dredging.
Few people know that the mud pumps of the dredgers suddenly increases in load without protection measures, and if the throttle of the main engine continues to increase at this time, it will cause damage. The mud pumps is the core soul of the whole ship for the dredgers, so you should pay attention to everything in the usual work, and what aspects need to be paid attention to during the use of the dredgers.The following is an introduction to the aspects that need to be paid attention to in the use of the dredgers.
1. The dredgers takes over
When taking over the shift, the dredgers operator should carefully check the "Equipment Operation Record", and check the spare parts, spare parts, tools and other items and materials.
(1) Before starting the generator set of the dredgers, the oil level, cooling water level and fuel oil level of the diesel engine must be carefully checked, and supplemented if necessary to keep them within the specified value.
(4) After the generator set of the dredgers is started, all indicating instruments indicate normal values, and must run at low speed for 3-5 minutes (if the weather is cold, it should be extended appropriately). Then gradually increase the speed until the voltage rises to 400V and the frequency rises to 50HZ. During the whole process of starting the unit, pay attention to whether there is any abnormal sound of the unit.
3. Power can be delivered after the distribution motor unit of the dredgers operates normally
When sending power, the sequence of closing the knife switch (double-throw knife switch) on the main switchboard first and then closing the generator air switch must be followed.

(2) Make sure that all the indicating instruments of the generator set of the dredgers are in the zero position, the air switch of the generator set is disconnected, the diesel engine speed control handle is in the low-speed starting position, and the generator set can be powered on after there are no tools and debris in each part of the generator set.
(4) After the generator set of the dredgers is started, all indicating instruments indicate normal values, and must run at low speed for 3-5 minutes (if the weather is cold, it should be extended appropriately). Then gradually increase the speed until the voltage rises to 400V and the frequency rises to 50HZ.
