How winter maintenance dredging

A winter maintenance dredging ship

 

1, before starting the first of the entire mechanical drive system and machine oil checked, and then start the pull back conveying diesel engine, with the pull clutch, start engine, slowly moving loose clutch, the speed adjusted properly. Then launch diesel bucket front zipper.

 

2, two after starting the diesel engine speed to will. The need for speed. Then release the brake arm. Slowly it down, other than the sand hopper 2/3, to stop decentralization, until 1/3 and funded under the arm. When the big arm and the water into a 45 degree angle, should be parked arm. Then how much sand in the hopper switch traction control.

 

3, The dredging forward to check How much sand in the bucket and fixed, forward and backward to be flexible in case of mechanical sand cave strenuous work or pull to loosen the rope, the ship backward until it stops digging. In case of large stones under water or mud, the ship will be severe vibration phenomenon, then immediately filed dredging arm, then avoid obstacles.

 

Two, the dredging bucket maintenance method

 

1, every 100h maintenance project. The boom cylinder head pin; boom foot pin; boom cylinder rod end; the bucket rod cylinder head pin; arm bucket rod, a connecting pin; the bucket rod bucket cylinder rod end; cylinder head pin; half rod connecting pin; the bucket rod bucket cylinder rod end; bucket cylinder head pin; the bucket rod connecting pin; oil level check box rotating mechanism (with oil); water and sediment discharge from the fuel tank.

 

2, every 250h maintenance project. The final drive oil level check box (add gear oil); check the battery electrolyte; replace the engine oil pan oil filter replacement engine; lubricating rotary bearing (2); check fan belt tension, and check the air conditioning compressor belt tensioning degree, and make adjustments.

 

3, every 500h maintenance project. At the same time every 100 250H and maintenance projects; fuel filter replacement; check rotary pinion grease height (grease); check and clean the radiator fin oil cooler, heat sink and chiller heat sink; replacement of hydraulic oil filter; change the oil in the final drive (only for the first time at 500h, after 1000h times); air filter cleaning device of air conditioning system of internal and external; replacement of hydraulic oil vent filter.

 

4, long-term storage. The machine being stored for a long time, in order to prevent the hydraulic cylinder piston rod rust, the work should be placed in a device; the washed and dried and kept in dry indoor environment; if conditions are only stored outdoors, the machine should be parked in the well drained water mud on the ground; storage before the full fuel tank, lubricating parts, replacement of hydraulic oil and lubricating oil, the metal surface of the piston rod of the hydraulic cylinder exposed coated with a thin layer of butter, remove the battery negative terminals of the battery, or will be unloaded separately; according to the lowest environmental temperature in antifreeze adding cooling water; and a month to start the engine the operation of the machine, In order to lubricate the moving parts and charge the battery at the same time, turn on the air conditioner to cool and run 5-10min.

 

Three, the daily maintenance of the pump

 

1, bearing water pressure, water quantity to meet the requirements, at any time to adjust (or replace) the degree of tightness of the filler, do not cause shaft seal leakage, and promptly replace the shaft IH pump shaft pump casing

 

2, the replacement of bearings, we must ensure that the bearing assembly dust-free, clean lubricants, pumps running temperature generally less than 60- 650C bearing is appropriate, the highest not more than 750C.

 

3, to ensure that the motor and pump coaxial, to ensure that the elastic pad in the coupling complete and correct, damaged should be replaced in a timely manner.

 

4, ensure that the pump components and piping system are installed properly and firmly.

 

5, parts of slurry pump are wearing parts, in daily use should pay attention to the loss of vulnerable parts, timely repair or replacement of the slurry pump. The vulnerability of the maintenance or replacement process to ensure the correct and reasonable gap adjustment, avoid tight Shibuya friction appearing.

 

6, the suction pipe system of slurry pump must be no leakage state, at the same time in the operation should pay attention to whether there is clogging. Suction entrance pump required to deal with the medium containing solid particles, so the grille into the pump pool placed should be consistent with the slurry pump can through the particle requirements into the pump body can cause reduction of the plug roots pump less than water ring vacuum pump of large particles or long fiber material.
