1. Inspection before starting the fire pump of the fire truck 1. Check the process valve switching conditions, and whether the corresponding return valve switching conditions meet the requirements. (1) During the daily test of the pump, the return valve should be fully open and the valve block valve should be in the closed position. When trying 1# foam pump and 2# pump foam outlet, it is necessary to close the three foam tank inlet valves Vp111, Vp112, and Vp212, and open the Px021 return valve to start the pump; try 2# pump water outlet, 3#, 4# fire truck The Px011 return valve must be opened when the fire engine fire pump is used to start the pump. After testing the pump, restore all valves to the specified state. (2) When there is an emergency or when water is needed for fire fighting drills, open the valve in the valve block corresponding to the position where fire water (foam) is needed, and the return valve is closed. (3) The inlet valve of the pump must have a normally open, and the outlet valve must be in the closed position. 2. Check that the clutch handle of the vacuum suction device should be in the “closed” position. 3. Open the air release valve and close the air release valve after resetting the float assembly. 2. Operation steps of starting and stopping the fire pump of the fire truck 1. After starting the pump, check the running current of the motor and whether the pump is running normally. If there is any abnormality, stop the pump immediately. 2. Observe the pressure gauge at the outlet of the water pump. When the pointer of the pressure gauge reaches the rated working pressure and is stable, gradually open the outlet valve to try to make the pump work in the rated state. 3. After the pump is normally filled with water, move the clutch handle of the vacuum suction device to the position of “divided”. 4. Observe the pressure of the valve group, the pressure of the clean water valve group is kept at about 0.8Mpa, and the foam valve group is kept at about 1.0Mpa. If the pressure cannot be maintained, the outlet of the pump and the return valve can be adjusted appropriately to control the pressure. 5. The temperature of the pump and motor bearings should be checked frequently. The maximum temperature should not exceed 75 degrees. Check that the working current of the motor should be within the normal range. 6. After stopping the pump, restore all valves to their normal state according to the requirements of the valve opening and closing state diagram. 7. Move the clutch handle of the vacuum suction device to the “close” position, open the bleed valve, reset the float assembly, and be in a state of preparation. 8. If the pump starts, if the pressure reaches 0.8Mpa and then immediately returns to about 0.4Mpa, the water cannot be discharged normally. At this time, stop the pump immediately, open the air release valve to reset the float assembly, and restart. 9. Under normal circumstances, one of the 1# and 2# stabilized pumps is in working condition and the other is in standby condition. Three, fire truck fire pump maintenance and maintenance 1. Check every shift and ensure that the power supply and circuit of the fire protection system are unobstructed, and the electrical equipment is in good condition. 2. Pump once per shift, the coupling should be uniform in weight, no abnormal noise, and make a record. 3. Check the lubricating oil level in the vacuum suction device on the 5th, 10th, 15th, 20th, 25th, and 30th days of each month, and the refueling position is on the center line of the oil window or slightly below the center line; start the fire engine for fire fighting Car fire pump, check the pump time and make a record, 1#, 2# pumps run for 15 minutes, 3#, 4# pumps run for 5 minutes. 4. After the pump is started, check the operation of the float assembly, and there should be no water in the exhaust hose. If there is water, the float seal must be replaced. 5. After the pump is started, check whether the size and sealing body of the vacuum suction device is tight and whether the exhaust is normal. 6. After the pump is started, check the sealing degree of the packing, and the leakage should not exceed 10-30 drops/min. 7. Regularly check the lubricating oil in each part of the pump to ensure that the lubrication system is working properly. 8. Regularly check whether each connection part is tight and whether it is loose. Keep the liquid level of fire A and B pools at 3.45m from the bottom of the pool, and build a new 1700m3 fire pool to ensure 70% of the water volume. 1. Inspection before starting the fire pump of the fire truck 　　　　 1. Check the process valve switching status, and whether the corresponding return valve switching status meets the requirements. 　　　　 (1) During the daily test of the pump, the return valve should be fully opened and the valve group valve should be in the closed positio

Loudi News Network (Reporter Wu Mingming, Correspondent Peng Weiguo Xie Huifang) In order to prevent fire accidents, strengthen the professional quality of township firefighting teams, and enhance the rapid response ability of part-time firefighting teams in fighting fires and disaster relief, June 4, Loudi City The part-time firefighting team skills contest of Xinhua County kicked off. 14 firefighting teams from across the county participated in this skill contest. The contest included laying and connecting two trays of hoses, motorized pump trains, and water guns. “Stay in position, prepare, start……”With the referee’s whistle, the players rushed out of the starting point like an arrow from the string, teammates on the side of the field shouted anxiously, and the players sweated and raced against time. There was a kind of "hot" atmosphere in the whole arena. The competition includes three projects: the water discharge exercise of the motorized pump train, the extension exercise of the hose at the water gun, and the connection of the two trays of the hose. There are sixty-year-old "veterans" and "newborn calves" on the competition field. Recruits”, everyone compares physical fitness, stamina, style, and courage. You chase after me, not to be outdone. The part-time firefighters have a tenacious fighting style and a brave fighting spirit. It is understood that the participating township and township part-time firefighting teams are composed of 7 members. According to the standard of "one vehicle, one team, one room", they are equipped with fire trucks, fire fighting equipment, and built a special fire fighting garage. , Each team can receive 60,000 yuan of special government funding each year, which fundamentally solves the "worries for the future". Xinhua County has a wide area and a large population. The 27 towns and towns under its jurisdiction are mostly remote villages. The rural fire protection infrastructure is weak, and various factors that induce rural fires are increasing year by year. Therefore, a township that can fight fires has been established. Part-time firefighting teams can not only effectively alleviate the current situation of insufficient firefighting police force, but also play an important role in safeguarding local economic construction. In recent years, the construction of the team has received strong support from the local county people's government. The Xinhua County Fire Brigade has continuously provided professional technical guidance in terms of fire fighting knowledge training and fire fighting drills. Through this competition, we comprehensively reviewed the business level of part-time fire brigades in various townships, improved the operational skills and fire fighting skills of part-time firefighters, promoted the construction of part-time firefighters, and created a high-quality, professional Towns and towns with strong fire fighting and rescue capabilities have laid a solid foundation for the "Patron saint". The relevant person in charge stated that currently, 14 part-time teams in towns and villages have been built and put into use, and strive to achieve 100% coverage of part-time teams in towns and villages next year. "Now, even if there is a fire in the most remote township, the part-time firefighting team of the township can rush to the scene for disaster relief as soon as possible. ”(Editor/Liang Xiongjun)
