In addition to investment costs, there are operating costs and manpower costs.
Development Trends After several decades of development, China's road sweeper industry has evolved from a single pure sweep model to a variety of current models. Product performance and product quality have rapidly increased, especially after the reform and opening up, through the import of key purchased parts. The performance and reliability of road sweeper products have been greatly improved. However, at present, there are still some gaps in the level of road sweepers in China compared with foreign developed countries, especially in terms of product reliability. In order to improve the level of road sweepers in China as soon as possible, narrow the gap with the level of road sweepers in advanced countries, and meet the requirements of China's environmental sanitation department for road sweeping operations, sweeper vehicle manufacturers should select a suitable road sweeper research direction. As society develops and progresses, it will no longer be satisfied with vacuum cleaners in a simple sense. It will put forward more requirements in terms of multifunctionality, environmental protection, and economy. The market calls for vacuum vehicles that can meet various needs. It is under the above circumstances that a brand new multi-function full-suction sweeper vehicle jointly developed by the China Construction Second Bureau Luoyang Construction Engineering Machinery Plant and Luoyang Chi Windmill Co., Ltd. has been officially put on the market. This brand-new model can complete floor cleaning, road side cleaning, road crossing, and road cleaning after sweeping. It is suitable for cleaning all kinds of climates and different dry roads. It is more suitable for squares and highways. , Dedusting and Cleaning of Residential Areas, Parking Lots, Docks, Airports, Stations, Cement Plants, Power Plants, etc.
Road sweeper maintenance 1, in order to avoid operating mistakes, sweeping vehicle control valve is mainly divided into the main valve and the secondary valve. Then where is the main difference between these two kinds of valves, where the power of the main valve comes from the chassis of the sweeper car, and the power of the secondary valve comes from the auxiliary engine of the dedicated function part. Common road sweeper deputy engines include Chaochai, Jiangling and Cummins. The main valve manages the tilting of the shell behind the chassis and the hydraulic switch on the rear door of the compartment. The secondary valve manages the operation of the four floor brushes (which can individually control one side or all of the work) and the suction cup of the sweeper. 2, The secondary engine of the road sweeper is different because the engine brand is selected for different power, but the general speed is around 1500 to 1800 rpm. 3, according to the needs of the work can generally choose whether you need to bring the function of water spray dust, conventional configuration generally comes with post-spray, at the same time need to pay attention to the clean water tank is enough water, the general clean water tank capacity is different, there may be a gap in working time. 4. The pressure adjustment of the electromagnetic multi-way valve of the road sweeper is generally on the overflow valve. Users can adjust the pressure appropriately to change the speed of the sweep brush. 5, In addition, according to the road conditions, the sweeping vehicle can select whether the left and right brushes of the vehicle work at the same time. For example, if the sweeping corner is only used to open the corner, the brush is turned to work. 6, dust bins may have small dust deposits in the dust bins of the sweeping vehicles, and manual manual handling is required when cleaning the dust bins. 7. The distance between the sucker of the sweeping vehicle and the ground should be adjusted according to the condition of the road section. 8, sweeping vehicle dust suction pipe may often have dust and mud adhesion, need to be cleaned regularly to achieve better results. 9, the electrical parts in the control box need to be replaced in order to use a more stable one. 10. Sanitation workers should regularly check whether the functional parts are normal. 11, in order to avoid the foreign matter in the hydraulic oil will affect the normal operation of the electromagnetic control valve, sanitation workers should regularly check the hydraulic oil is normal. 12. Check whether the limit device of the clutch electric push rod of the secondary engine of the vehicle is normal. 13, sweeping car control button when the time interval should be 5 seconds 14. When a hydraulic part of the road sweeper is not working properly, check the circuit first and then check the circuit. (1) The possible causes of the abnormal circuit part are: disconnection of insurance, loose connection of circuit, broken line (2) The possible causes of the abnormal oil line may include: failure of the oil pump, rupture of the oil pipe, or oil leakage at the oil line connection, or malfunction of the solenoid valve.

The demand for drivers There are more and more road sweepers and private cars nowadays, and they are getting more and more boring. The reason is that some owners have poor driving skills and poor psychological skills. First, the heart of the driver of the road sweeper, driving the car requires good psychological quality, not everyone is suitable for driving, if you do not have patience, and there is no keen observation ability, especially rapid response ability you are not suitable for driving. Second, the theoretical quality of the road sweeper driver, driving learning can only make people master the initial driving, but more technology through the experience needs and the actual driving experience in the process of slow experience, summary accumulation. Third, the driver's driving skills of the road sweeper driver must be familiar with the vehicle's instructions for use. It is necessary to know which vehicle tools and methods are used. He is familiar with the four-oil and three-fluid inspection and supplement methods. Learn to clean the air filter element yourself. Fourth, the ethical qualities of road-sweeping car drivers, when driving past pedestrian waters, quickly reduce the speed, do not whistle after entering the community, and use lights strictly in accordance with regulations. Courtesy makes way.
Suggestions for the run-in period 1. Maintain a smooth start, avoid slamming the throttle, and do not make the engine speed too high. 2. Before starting, the water temperature should reach above 50°C. Start with a low block and switch into a high block after 1 km. The water temperature in the vehicle should be controlled at 80°C-90°C. 3, timely shifting during the journey, do not use a gear for a long time, can not use high-speed gear at low speed or use low-speed high-speed driving. ? 4, choose a good road, to avoid excessive vibration, collision or emergency braking. Before the brake, the clutch should be divided. 5, the choice of high-quality fuel and oil, should not use engine wear additives.
Precautions Vehicles that are in the run-in period should always be checked regularly to detect problems and eliminate them. 1. Oil, cooling water, tire gas, etc. must be sufficient, no leakage occurs, and should be promptly replenished if found to be in deficit. 2. If there are abnormal noises in each part, it must be repaired in a timely manner. The impact of mechanical failure during running-in on the vehicle is often much greater than that caused by mechanical failure during the over-run-time period. 3. There are warning lights in the dashboard on the general car, and some cars are even equipped with computers. The alarm information in the dashboard and the computer is discovered in time to better control the condition of the vehicle.
Transmission classification analysis and maintenance Cleaning sweeper gear type stepless transmission can be divided into two-shaft and three-axle transmissions according to different structures. The two-axle transmission is widely used in front-front-engine driven passenger cars, and the three-axis transmission can be applied to various other types of vehicles. Continuously variable transmissions are rarely used in cleaning sweeping vehicles. They are usually powered by metal belts. Continuously variable speed is achieved by changing the diameters of the main and driven pulleys. The change in transmission ratio is continuous. The use of transmissions in medium and advanced passenger cars is increasing. [1] The integrated transmission is composed of a hydraulic torque converter and a geared transmission. Generally, the microprocessor controls the shifting automatically. Therefore, the transmission is often referred to as an automatic transmission. The transmission ratio of this type of transmission can be changed steplessly within several intermittent ranges between the maximum value and the minimum value, and it is currently applied more to the cleaning of sweeping vehicles. Also note here that the number of gears in the transmission refers to the number of forward gears. In general, a five-speed manual transmission means that there are five forward gears. The maintenance inspection of the cleaning clutch mainly includes checking the free travel of the clutch pedal, checking the working condition of the clutch, and checking the liquid level of the clutch tank. First, check the liquid level of the clutch reservoir: Check the height of the clutch fluid (brake fluid) surface in the master cylinder reservoir. If it is lower than the "MAX" mark, it should be added, and further check the hydraulic pressure of the clutch. Whether the organization has a leak. Leakage inspection of the hydraulic operating mechanism is mainly to check whether there are traces of clutch fluid in the master cylinder and the oil pipe, the working cylinder and the oil pipe, and the oil seal. Second, the sweeper clutch pedal check: 1 step on the clutch pedal, check whether there are the following failures: 1) pedal rebound weakness; 2) abnormal sound; 3) the pedal is too loose; 4) heavy pedal. 2 Check the clutch pedal height: Check the height of the clutch pedal, lift up the carpet or floor leather, and use a ruler to measure the distance from the ground to the upper surface of the clutch pedal. If you exceed the standard, you should adjust the pedal height. The height of the clutch pedal can be adjusted by the limit bolt behind the pedal. 3 Check the clutch pedal free travel. Check the free travel of the sweeper pedal: Use a ruler against the floor of the cab to measure the height of the pedal when it is completely relaxed. Then tap the pedal by hand. Measure the pedal height when the resistance increases, the height of the two measurements. The difference is the free travel of the pedal. The adjustment of the pedal free stroke, the hydraulic control mechanism is generally to adjust the length of the master cylinder push rod, the master cylinder push rod lock nut is loosened first, then the master cylinder push rod is turned, thereby adjusting the pedal free stroke, and the lock should be adjusted Tighten the nut tightly.
