Sprinkler usage and operating procedures

The first rule

1. The sprinkler operator (driver) must abide by the regulations of this regulation to ensure the safe operation of the sprinkler, give full play to the effectiveness of the equipment, and improve the capability of watering and dust reduction. Safety, efficiency, energy saving, and consumption reduction are central to the work of sprinkler drivers.

2. The sprinkler driver must hold the "People's Republic of China Motor Vehicle Driving Licence" (on A2) and the "Promotion Card" issued by the mining company when he is on duty. At the same time, he must wear labor protection products as required.

3, based on their own work, study technology, improve skills, give full play to subjective initiative; familiar with equipment performance, close cooperation, so that "three understandings" (principle, performance, structure), "four" (use, maintenance, inspection, Troubleshooting.

 

Second operation requirement

Prior to the operation of the sprinkler, the engine must be inspected in accordance with the procedures and requirements stipulated in the safety technical operating rules of the diesel engine, and the daily maintenance and maintenance of the sprinkler must be done:

1. On the basis of daily inspection items before the shift, drivers of the sprinkler must observe obstacles, objects, and personnel before, after, and on the left and right sides of the equipment. After confirming safety, they can start the engine (starting the engine before singing a long horn and starting walking Before the two short horns, three horns will be heard when reversing.

2. When checking the engine oil of a cold engine, its oil level must be in the middle of the oil dipstick, and must not be lower than the lower line. Check the engine coolant, the liquid level can not be less than 50mm below the water inlet. When the hot car checks the liquid level of the coolant, the tank pressure must be released to prevent steam from hurting people. Check the fuel level of the fuel tank, check the dust indicator, check the monitoring system, water and sediment of the water separator discharging the fuel tank.

3. Before starting the engine, all the operating handles must be placed in the neutral position, and check whether the instrument is in good condition and whether the battery voltage is normal.

4. Place parking brake lever in “ON” position;

5. Place the shift selector switch to "N" (mid-range);

6. Turn the key to the "ON" (power on) position, and the parking brake indicator will light up at this time;

7. Set the indicator test switch to the “ON” (test) position. All warning lights powered by the system should glow. Otherwise, maintenance personnel must be notified. in case

When the warning light is working, the pilot light switch is released and the “Start Engine” section is referenced.

 

Article 3 Engine Startup Notes

1. When the engine used by the sprinkler is started in the winter season, except in accordance with this regulation, it shall be started by referring to the relevant procedures of the equipment operation manual. First of all, it is necessary to use various preheating methods for engine warm-up () such as engine oil preheating, antifreeze preheating, fuel preheating, etc.). In winter, cold starters should obey the command of engineering technicians, and the driver has no right to cold start the engine without permission.

2, in addition to taking auxiliary warm-up method, you must use the start warm-up device for preheating 1 ~ 3min.

3, to promote the auxiliary (ether) button, every 2s to give an additional starter solution (ether) (without the permission of the technician can not use ether start), in less than -18 °C must first perform auxiliary warm-up, and then the switch Push the warm-up start switch inward to warm up until it starts.

4. Avoid excessive use of ether in winter, otherwise it will damage the parts or cause explosion due to excessive pressure.

5. After the engine is started, it should be idling for 5 minutes in winter, and it should be accelerated after 3 minutes in summer, but the idle time should not be too long. After the engine is started, it should be warmed up to 40°C or above before it can start. After the car starts, it should be driven at a low speed initially to warm up the transmission and rear axle transmission system. When the engine coolant temperature rises to the normal value (80--90 °C ), normal full-load operation can be performed. Pay attention to keep the engine hot during driving.

 

Article 4 Start the engine

1, fasten the seat belt;

2. Set the gear selector of the gearbox to “N” position;

3. Trumpet three rings to warn people around the sprinkler;

4. Turn the (STAET) switch to the START position. Immediately after starting the engine, the switch is returned to the spring-loaded (RUN) position;

5. Observe the conditions of the meters and alarm indicators on the instrument panel:

1) The parking brake indicator should glow until the air system pressure exceeds approximately 90 psi (620 kbar) or the parking brake switch is set to the "OFF" position.

2) If the engine oil pressure does not reach the operating pressure within 30 seconds, shut down the engine immediately;

3) If the operating pressure cannot be reached within 30 minutes of transmission oil pressure, shut down the engine immediately.

4) Check the air pressure gauge on the dashboard. The car can only be operated when the air pressure reaches 125 psi (1034 kPa); the pressure alarm will sound when the air pressure is below 90 psi (620 kilobars);

5) The low oil pressure warning light will glow until the oil pressure rises within the normal operating range.

6) Let the engine idle at least 5 minutes, but the idle time should not be too long.

 

Article 5 Check Before Starting the Sprinkler

1, check the air pressure gauge. Do not operate the car until the air pressure does not reach the minimum pressure of 125 psi (861 kBar);

2, check the steering operation, if the dynamic steering is in normal work, just a small amount of effort can turn the steering wheel;

3, check the head class, tail lights, parking lights, reversing lights, dashboard lights, air horns and wipers are working properly;

4. Check whether the operation of parking brake and emergency brake system is absolutely safe.

5, check the transmission oil pressure;

6. After the oil reaches the operating temperature, check whether the oil level of the transmission oil is at its position.

7. Check the ammeter to see if the charging flow is proper;

8. Check the alarm indicator, the flashing and air pressure alarm buzzer beep before the start of the sprinkler;

9, drain water from the spray, in-line air filter and the water in the reservoir;

10. Check the oil level in the hydraulic tank;

11. Check the air filter indicator.

 

Article 6 The start of the sprinkler

1. Make sure that all personnel, equipment and other obstacles are in a safe location. Sprinklers must make two loud horns in front of the sprinkler, three horns in the reverse, and a side position when reversing;

2. Push the gear selector selector handle to a suitable position;

3, release parking brake;

4, the function of the work brake is wrong;

5, air pressure loss, or lower than the air pressure alarm buzzer call;

6. Unusual noise or unstable system behavior;

7, the engine does not respond to the operator's request.

 

Article 8 Sprinkler parking

1. When the sprinkler is parked, it is necessary to stop the sprinkler completely, switch the gearbox to “N” (middle gear), and apply parking brake;

2. In view of the internal heat generated during engine operation, it is necessary to slowly cool it down so as not to damage the engine and the turbocharger. Before shutting down the sprinkler engine, allow it to idle for three to five minutes. This will allow the lubricating oil and cooling system to walk the tropical heat of the combustion chamber, protecting the engine from serious damage to the bearings, crankshaft and oil seal;

3, shut down unused other appliances.

 

Article 9 Sprinkling Practice

1. After the sprinkler adds water, the load is floated by the center of gravity of the liquid, and the speed is limited to 35Km/h;

2. The width of the work surface should not be less than 10 meters, and there should be room for turning head, which is equivalent to 5 times the distance of the body;

3. Obstacles can be seen as normal, and it is forbidden to rewind without any command;

4. Adjust spray thickness and spray volume according to seasonal changes. Continuous spraying and intermittent spraying can be implemented according to actual conditions;

5, the safe use of high pressure water cannons. Some auxiliary drivers for waterwheels have an obligation to explain with the use department. The use of water, scouring, and fire extinguishing must be done with the approval of the supervisor of the foreman or above and the presence of professional personnel at the scene.

6. When the road surface is sprinkling, from the rear view mirror, when there is a car immediately following the flushing of the windshield, there is no special situation in front that must not be decelerated rapidly. The dual flashing lights should be used to indicate the driving distance.

7. In the absence of a warming storage in winter, the tank body, pipelines and valves must be put in place to ensure that they can be put in clean water before they stop. The sprinkler truck pumps and piping system can be prevented from freezing, and the torch can be used to discharge water when necessary.

 

Article 10 Transfer of Sprinklers and Acceptance of Mission Requirements

1. When the watering truck driver carries out the shift, he must pay close attention to the status of the equipment, especially the existing problems and the task of completing the task in this class, as well as instructions and precautions from the superior.
