The first general rule
1, sprinkler operators (drivers) must abide by the provisions of this regulation, ensure the safe operation of sprinklers, give full play to equipment efficiency, and improve the dust suppression ability of sprinklers. Safety, high efficiency, energy saving and consumption reduction are the center of sprinkler driver's work.
2. Sprinkler drivers must hold People's Republic of China (PRC) (B2) motor vehicle driver's license and work permit issued by the mining company when taking up their posts, and wear labor protection articles as required.
3, based on their own work, learning technology, practical skills, give full play to the subjective initiative; Familiar with equipment performance, cooperate closely, and achieve "three understandings" (principle, performance and structure) and "four skills" (use, maintenance, inspection and troubleshooting).
Article 2 Operational requirements
Before the sprinkler is operated, the engine must be inspected according to the procedures and requirements specified in the Operating Rules for Safety Technology of Diesel Engine, and the sprinkler should be well maintained daily:
1. Sprinkler drivers must observe whether there are obstacles and people on the front, back, left and right sides of the equipment on the basis of pre-shift inspection items, and can only start it after confirming safety (sound a long horn before starting the engine, two short horns before starting driving, and three horns when reversing).
2. When checking the engine oil in the cold car, the oil level must be in the middle of the upper and lower parts of the dipstick, and cannot be lower than the downline. Check the engine coolant, and its liquid level should be no less than 50 mm below the water inlet. When the hot car checks the coolant level, it must release the pressure of the water tank to prevent the steam from hurting people. Check the fuel tank oil level, dust indicator and monitoring system, and drain the water and sediment from the fuel tank oil-water separator.
3. Before starting the engine, all operating handles must be placed in the middle position, and check whether the instrument is in good condition and whether the battery voltage is normal.
4. Place the parking brake lever in the "ON" position;
5. Turn the gear selector switch to "n" (middle gear);
6. Turn the key to the "ON" position, and the parking brake indicator will light up;
7. Turn the indicator test switch to the "ON" position. All alarm lights powered by the system should be lit, otherwise, the maintenance personnel must be informed. If all warning lights are working, release the indicator test switch and refer to the section "Starting the engine".
Article 3 the winter start the engine matters needing attention.
1. When starting the engine for sprinkler in winter, in addition to this regulation, it should also be started according to the relevant steps in the equipment operation manual. First of all, we should use various preheating methods to preheat the engine (such as engine oil preheating, antifreeze preheating, fuel preheating, etc.). ). The cold start in winter should follow the command of engineers and technicians, and the driver has no right to start the engine without authorization.
2. In addition to the auxiliary preheating method, the startup preheating device must be used for preheating 1~3min.
3. Press the auxiliary (ether) button, and replenish the starting fluid (ether) every 2s (ether shall not be used for starting without the permission of technicians). When the temperature is lower than-18℃, auxiliary preheating must be carried out first, and then the switch is pushed inward to preheat until it is started.
4, avoid excessive use of ether in winter, otherwise it will damage parts or cause explosion due to excessive pressure.
5. After the engine is started, it should idle for 5 minutes in winter and accelerate after 3 minutes in summer, but the idle time should not be too long. After the engine is started, it should be preheated to above 40℃ under no-load before starting. After automatic starting, you should initially drive at a low speed and warm up the transmission and rear axle transmission system. Only when the engine coolant temperature rises to the normal value (80-90℃) can it drive normally with full load. Pay attention to keep the engine warm when driving.
Article 4 Start the engine.
1, fasten your seat belt;
2. Set the gear selector of the gearbox to the "middle range" (N) position;
3. Sound the horn three times to warn people around the sprinkler;
4. Turn the STAET switch to the starting position. Return the switch to the spring-loaded (running) position immediately after the engine is started;
5. Observe the tables and alarm indicators on the dashboard:
1) The parking brake indicator should illuminate until the air system pressure exceeds about 90 psi (620 kPa) or the parking brake switch is placed in the "OFF" position.
2) If the oil pressure can't reach the working pressure within 30 seconds, shut down the engine immediately;
3) If the transmission oil pressure cannot reach the working pressure within 30 minutes, immediately shut down the engine.
4) Check the barometer on the instrument panel. When the air pressure reaches 125 psi (1034 kPa), the car can run; When the air pressure is lower than 90 psi (620kbar), the pressure alarm will sound;
5) The low oil pressure alarm indicator will light up until the oil pressure rises to the normal working range.
6) Let the engine idle for at least 5 minutes, but the idle time should not be too long.
Article 5 Sprinklers shall be inspected before being put into use.
1, check the barometer. Do not operate the car until the air pressure reaches the minimum value of 125 psi (86 1 kPa);
2. Check the steering operation. If the steering is normal, you can easily turn the steering wheel.
3. Check whether the first shift, taillights, parking lights, reversing lights, instrument panel lighting, air horn and wiper are working normally;
4, check the parking brake and power emergency braking system operation is foolproof.
5, check the gearbox oil pressure;
6. After the oil rises to the working temperature, check whether the oil level of the gearbox oil is in a proper position;
7. Check the ammeter to see if the charging flow is appropriate;
8. Check the alarm indicator. Before the sprinkler starts, there are flashing lights and air pressure alarm buzzers.
9. Drain the accumulated water in the spewing, in-line air filter and gas storage tank;
10, check the oil level of the hydraulic oil tank;
1 1. Check the air cleaner indicator.
Article 6 the sprinkler began to run.
1. Ensure that all personnel, equipment and other obstacles are in a safe position. Sprinklers should sound two horns when moving forward, three horns when reversing, and a lateral position meter should be used when reversing;
2. Push the gear selection handle of the gearbox to a proper position;
3. Release the parking brake;
4. Step on the accelerator lightly and start smoothly;
5. Increase the speed and check the operation of the service brake and power deceleration system.
Article 7 Several situations of emergency stop
1, the engine temperature exceeds the allowable range;
2. The engine oil pressure is higher or lower than the allowable range;
3, hydraulic deceleration system failure;
4, the function of the work brake is wrong;
5, air pressure loss, or lower than the air pressure buzzer alarm;
6, abnormal noise or drift unstable system action;
7. The engine did not respond according to the operator's requirements.
Article 8 sprinkler parking
1. When the sprinkler stops, completely stop the sprinkler, switch the gearbox to "N" (middle range) and apply the parking brake;
2. Since the engine will generate heat internally during operation, it needs to be cooled slowly to avoid damaging the engine and turbocharger. Let the sprinkler engine idle for three to five minutes before turning it off. This will make the lubricating oil and cooling system take away the heat of the combustion chamber and protect the engine from serious damage of bearings, crankshafts and oil seals;
3. Turn off other unused appliances.
Article 9 the sprinkler operation specification
1. After adding water to the sprinkler, the load floats at the center of gravity of the liquid, and the speed is limited to 35 km/h;
2. The width of the working road surface is not less than10m, and there is room for turning around, which is equivalent to 5 times the distance of the car body;
3. Obstacles can be seen clearly, so you can drive normally. It is strictly forbidden to reverse without orders;
4. Adjust the thickness and quantity of water spray according to seasonal changes. Continuous spraying and intermittent spraying can be implemented according to the actual situation;
5, the safe use of high-pressure water cannon. Drivers are obliged to explain some auxiliary uses of waterwheels to the user departments. The use of water supply, flushing and fire fighting must be approved by the leaders above the foreman on duty and used under the command of on-site professionals.
6. When sprinkling water on the road surface, when the rearview mirror finds that there is a car behind washing the windshield, if there is no special situation ahead, it is not allowed to slow down sharply. Double flashing lights should be used to signal the rear car to keep the driving distance.
7. When there is no warm storage in winter, water tanks, pipelines and valves can only be stopped after fresh water is put in to prevent the spray pump and pipeline system from freezing. When necessary, the water can be discharged while baking with a blowtorch.
Article 10 Requirements for handover and acceptance of sprinkler tasks
1. Sprinkler drivers should pay attention to the status of the equipment, especially the existing problems, the completion of the tasks of the class, and the instructions and precautions of the superiors when changing shifts. Successive drivers should memorize the contents of safety disclosure.
2. During the handover, the sprinkler driver should * * check the maintenance items and the items before driving (check fuel, lubricating oil, hydraulic oil, gearbox oil, water or antifreeze, etc.). ).
3. Hand over the accessories and tools attached to the vehicle face to face, and carefully hand over the road shape changes of highways, mine lines and garbage dumps and the safety precautions during driving.
4, the driver should check the following work when picking up the car:
1) Check the tire pressure and tire wear. Whether the tire bolts are loose. Note that if it is a new wheel, after the vehicle runs 10 km to 20 km, the tire bolts should be tightened again according to the specified torque.
2) Check the height of the nitrogen cylinder and whether the connecting bolts of the transmission shaft and steering system are fastened.
3) Check whether the wet and dry road selector and emergency steering are in good condition.
4) Check whether the service brake, parking brake and hydraulic system are in good condition and reliable. If there is any fault, it must be repaired before starting the vehicle.
5) Check whether the engine oil, gearbox oil, fuel oil, lifting hydraulic oil and water are sufficient, whether the oil tank and water tank cover are complete and good, and whether the oil quality is normal.
6) Check whether the electrical, lighting and horn instruments are normal.
7) When the engine is idling after starting, the pressure indication shall be no less than 25~35psi. After idling for 5 minutes, part of the engine oil is preheated, and the water temperature rises to 40℃ and then the load is added.
8) Check whether the lifting effect of the lifting cylinder is good, and whether the lubrication of the running friction parts of each component is normal.
9) Check whether there are stones in the middle of the twins and the cleanliness of the vehicle.
10) Check whether there is any leakage in the pipeline and interface parts of the air system.
1 1) The driver on duty should immediately deal with the problems found in the inspection. If necessary, please ask the maintenance personnel for help, and never accommodate their work.

Is nursing a nurse? ?
Health managers are becoming more and more popular, and nurses are more favorable for registration! As we all know, the State Council has cancelled 15 medical-related qualifications, including nutritionists favored by nurses. However, under the background of the vigorous development of China's health industry, health managers have become another popular occupation suitable for nursing staff. Should nurses participate in it? What kind of occupation is a health manager? Health manager refers to a professional engaged in health monitoring, analysis, evaluation, health consultation, guidance and health intervention. According to the National Professional Standard for Health Managers, health managers are divided into three grades. What needs to be pointed out here is that at present, the National Health and Family Planning Commission only carries out the professional qualification appraisal of three-level health managers. The main tasks of a health manager include: ① collecting and managing health information of individuals or groups; ② Assessing the health and disease risks of individuals or groups; ③ Health consultation and guidance for individuals or groups; (4) formulate individual or group health promotion plans; ⑤ Health maintenance of individuals or groups; ⑥ Health education and promotion for individuals or groups; ⑦ Develop health management technology; ⑧ Evaluate the effectiveness of the application of health management technology. Benefits of nurses obtaining evidence 1. Demand of nursing work At present, the field of nursing service is gradually expanding from medical institutions to communities and families, and the service content extends from clinical treatment of diseases to chronic disease management, aged care, long-term care, rehabilitation promotion and other fields, which requires a large number of health management manpower to fill the gap. In addition, the service model of "three divisions * * * in one", which is developed vigorously in the medical reform, has led to the sinking of high-quality medical resources to the grassroots, among which health managers are nurses. 2. Nurses need more practice. In recent years, the public's demand for public medical and health services has become increasingly multi-level and diversified, and the connotation and extension of nursing services have gradually changed. The demand for primary health care, health management, elderly care, chronic care, hospice care and continuous care for emergency patients has increased. The rapid development of health service industry, such as the combination of medical care, social capital to run medical services, and "internet plus nursing", has further expanded the field of nursing services, and nursing services have gradually extended from institutions to communities and families. At the same time, the construction of graded diagnosis and treatment medical service system puts forward new requirements for primary nursing service ability. 3. The needs of the development of the workplace The vigorous development of the health industry will definitely make hospitals participate in it, such as health management, health guidance and health assessment. It will also become one of the development directions of hospitals. With the aggravation of population aging and the gradual deepening of medical reform in China, health management will become one of the key development directions and a stage for nurses to display their professional skills, whether it is required by national policies or economic benefits, even if they work in medical institutions.
