precautions for buying stocks:
1. Investors need to understand that the stock market will not drop pie. When someone is fooling you, the stock market will fall into traps, you need to always remember that the responsibility of the media in the stock market is to serve the sales volume, and the bounden ty of professors is to serve the media, Never believe what these people say. When speculating in the stock market, we also need to do justice to kill our relatives. If we say that we turn over, we will turn over. Because speculating in the stock market is the same as racing car, sometimes we need to stop, sometimes we need to rush. Don't think about rushing forever, because we will be killed
In the mature stock market, the turnover rate is 100% every year, but in China's very immature stock market, the turnover rate of shareholders can reach 1200% every year, which shows that most investors in China's stock market are doing short-term speculationto engage in the so-called gambling activities in the stock market is not to invest. In fact, the psychology of gambling in stock speculation is also a kind of abnormal psychology. If you use this psychology to speculate in stocks, you will definitely lose more than you earn
3. Many investors will die in the bear market, mainly because there are some problems in their stock speculation ideas. Because of the concept of the problem, will lead to these people's stock strategy mistakes. Therefore, it is suggested that investors should take the current point as a reference, small up, small up, big up, no up, no buy

6. Your single track is so big. It's almost the same as a real car. At least you need a heavy truck diesel engine for power
such a large track can be machined with a milling machine. In addition, the track thickness is too thin, according to your length and width, the thickness of 7 ~ 10mm is more appropriate, you can refer to the crawler excavator. It costs at least several hundred thousand to make this car. It's estimated that it won't be allowed to go on the road

7. Maintenance can be roughly divided into three parts:
1. One part is daily technical maintenance, that is, the operator can reasonably keep, daily overhaul, regular maintenance and correct operation and use of machines and tools in the process of use, which can prolong the service life of machines and tools and improve the application effect of machines and tools
2. The other part is periodic technical maintenance, that is, the maintenance content that cannot be solved by the operator's own conditions and means, such as the repair or replacement repair of the main parts of the machine, the overhaul and inspection adjustment after a certain period of use, must go to the maintenance point designated by the special manufacturer for professional repair
3. Finally, the technical maintenance of long-term parking. Because the paver is different from other machinery, especially in Qinghai, it is basically not used in winter, so maintenance should also be carried out
paver is a kind of specialized proction tool with high technology content and relatively complex structure. Generally, the working conditions for operation are relatively poor, and the technical level and professional knowledge quality of operators are quite different. In the process of use, e to the graal wear of moving parts and the influence of various external operating conditions, various mechanisms and parts will graally proce different degrees of natural loosening and mechanical damage, which will lead to the deterioration of paver power and economy, the rection of safety and reliability of parts, and unexpected mechanical failure will occur, which will affect the service life of paver. Therefore, in order to improve the service life and rece the occurrence of mechanical failure, maintenance work should be done well. Therefore, the use of paver management can not be lack of maintenance of this link
gearbox is one of the important transmission components of wheel loader. It is responsible for transmitting the speed and torque from the engine to the final drive system, changing the transmission ratio between the engine and the wheel, realizing the forward and reverse gear control of the loader, and cutting off the power transmitted to the walking device when the engine is running, In order to meet the needs of loader operation and driving, easy to start and stop the engine safely
however, in the working process of loader, the failure rate of gearbox caused by improper use and maintenance is always high, especially the failure to strictly abide by the maintenance proceres in use and the lack of timely inspection and daily maintenance will accelerate the formation of gearbox damage and failure, and even expand the harm of failure consequences< First, the purpose of preventive maintenance
1. Through tracking and checking the operation of the loader, stop the machine in a planned way, and arrange the maintenance and repair of the gearbox
2. To prevent the main mechanical failure and the damage of related parts, repair before the failure germinates, so as to save a lot of maintenance costs
3. Make the parts of the whole machine have a long service life, improve the efficiency of the equipment and maintain good working performance
4. Rece the maintenance difficulty and workload
2. Common faults and causes of wheel loader gearbox
1. When in gear, it can't smoothly enter gear< The reasons are as follows:
(1) the pressure of pressure valve is too low
(2) the hydraulic pump is not working well and the seal is not good
(3) the hydraulic pipeline is blocked
(4) damage and leakage of clutch sealing ring
(5) the shift valve rod is not in place
2. When the transmission changes speed, the gear cannot be disengaged. The reasons are as follows:
(1) the piston ring is swollen
(2) the clutch friction plate is burnt out
(3) failure or damage of clutch return spring
(4) the return line is blocked
3. It has been put into gear, but the loader is weak and even can't walk< The reasons are as follows:
(1) the friction plate is seriously worn and the clearance is too large
(2) the seal of clutch automatic empty valve is not tight, which makes the pressure drop
(3) the pipeline of shift control valve is blocked
(4) the shut-off valve cannot return
(5) the positioning spring of the variable speed valve is tired or broken, and the steel ball jumps
(6) the clutch piston ring and sealing ring are worn seriously, which leads to serious leakage
4. The operating pressure is too low< The reasons are as follows:
(1) insufficient oil in the transmission oil pan
(2) the main oil passage leaks oil
(3) the transmission filter is blocked
(4) the steering pump (or hydraulic pump) is damaged, causing serious internal leakage
(5) the pressure of the transmission pressure regulating valve is not adjusted properly
(6) the shift pressure valve spring is invalid or broken
5. The transmission automatically shifts out of gear or out of gear< The main reasons for the failure are as follows:
(1) the positioning device of the shift control valve fails. The main reasons for the failure are serious wear of the positioning ball or failure of the spring 2) Due to the long-term use of the shift control lever, the position and length of the lever change, and the proportion of the lever is not accurate, resulting in the deviation of the operating position, resulting in dislocation< According to JB / z194-83 and combined with the actual maintenance, the following regulations should be followed:
(1) routine maintenance: check the oil level of the low oil case
(2) 50 hours (or weekly): check whether the speed control handle is flexible and effective
(3) 250 hours (only after the first 250 hours): clean the transmission oil pan and the transmission oil filter element
(4) 500 hours: clean the oil pan filter and change the transmission oil
(5) 2000 hours: disassemble the gearbox and torque converter for inspection and repair
2. The hydraulic transmission oil is the energy carrier for the normal operation of the transmission. In the hydraulic transmission system, the pressure, temperature and flow of the working fluid determine whether the transmission can work normally. Therefore, in the daily maintenance of the transmission, special attention should be paid to the inspection and replacement of the hydraulic transmission oil
(1) fixed oil change interval and correct oil change interval is the key to maximize the working life of transmission components. Only by ensuring a reasonable oil change interval can the lubrication and protection characteristics of lubricating oil be brought into play. Generally, it should be based on the maintenance period recommended by the manufacturer, but this can only be relative, and it must be combined with the oil sample extraction and analysis results to know the actual working situation. For example, the maintenance manual requires that the oil change interval of the gearbox is 500h. According to the operation condition of the loader, we conct a sampling analysis on the oil sample every 250h or 100h to decide when to change the oil. However, when the lubricating oil is used for 1000h, it should be changed immediately. In addition to the regular replacement of new oil, in the usual inspection, if the oil is found to be deteriorated or mixed with impurities, it should also be cleaned and replaced with new oil
(2) the oil temperature should reach 40-50 ℃ and the oil flow should be discharged under the condition of agitation, and the dirty oil should be drained completely as far as possible; When refueling, you should use a tanker with filter device to add oil
(3) use the correct oil for the transmission system, and the lubricating oil used for the transmission must meet the specifications. It should be noted that diesel oil can not be added to the gearbox, because the diesel oil will rece the friction between the piston and other moving parts, while the oil used in the transmission system should allow a certain friction between the friction plates when they are combined, which is crucial for the normal operation of the transmission system. Only the correct use of lubricating oil can effectively extend the working life of clutch friction plate. At the same time, the correct use of oil can significantly improve the anti-wear performance of gears, eliminate clutch slip phenomenon, control the shaking and abnormal sound of braking, increase the braking force and provide greater traction. At present, the most commonly used hydraulic transmission oil is 6 and 8 hydraulic transmission oil
(4) refer to the filter replacement cycle provided in the maintenance manual, replace the filter in time, clean the filter screen, drain magnet plug and vent plug, and add lubricating oil according to the standard amount. If the viscosity of the transmission oil is too high, the transmission efficiency of the transmission will be low, the fluidity is not good, which is not concive to heat dissipation, and the local dry friction may appear between the high-speed relative moving parts, which is not concive to lubrication; If the viscosity of the transmission oil is too small, it can increase the leakage, cause the control oil pressure of the transmission to be too low, form a fault, the oil film strength between the transmission parts with large load is not enough, cause the early wear of the transmission parts, so it is not concive to lubrication. At the same time, a small amount of bubbles will be proced in the normal operation of the gearbox e to the oil stirring of the gear. In order to prevent the bubbles from accumulating more and more, cavitation will occur, which will rece the thickness of the oil film and affect the operation of the internal clutch and its control valve of the gearbox, the gearbox oil must have the characteristics of anti foaming. Therefore, the use of appropriate transmission oil can not only protect the transmission, prolong the service life of the transmission, rece the failure rate of the transmission, but also rece the direct cost of oil change and maintenance of the transmission, as well as the maintenance labor and parking time of the transmission
(5) all kinds of lubricating oils must be pure, precipitated for a period of time, and meet the specified quality requirements&# 8226; The oil filling tools, containers and oil filling ports shall be cleaned to prevent water and dirt from entering the oil&# 8226; When checking the fuel quantity, the vehicle must be horizontal in both longitudinal and transverse directions&# 8226; Be sure to check for oil leakage after refueling and changing
therefore, it is very necessary to strengthen the fault prevention and routine maintenance of the gearbox in the process of daily use, which can not only rece the low efficiency and delay of working hours caused by downtime, but also prevent and avoid the occurrence of larger subsequent faults, rece the maintenance cost and improve the safety of the machine
1. Due to the complex internal parts of the milling machine, the main working part of the machine is composed of milling cutter, bearing, gasket and milling drum. Due to the friction with the road for a long time in the operation process, the fastest consumption is also this part. Regular replacement and inspection can better extend the service life of the machine. It is best to operate by professional personnel and read the operation manual carefully
3. The milling cutter shaft should be inspected every day. If the groove on it exceeds 25% of the diameter of the cutter shaft, it should be replaced. Generally speaking, the life of cutter shaft is half of that of tungsten steel milling cutter. In terms of square area, its service life is 350-500 square meters when the milling depth is 5mm. But please note that there are many factors that will affect the life of the cutter shaft, so check it daily
4. Check the oil level before each operation and clean the air filter after use; Grease the bearing every 4 hours. When applying grease, rotate the milling drum while applying grease to the whole bearing.
5. Visually check the machine before each operation: are all fasteners tightened? Are there any parts obviously worn or cracked? Is the oil supply circuit in good condition? Check the bearing, check whether each protective cover is covered, etc
6. Generally speaking, milling cutter cracking is very rare. If it occurs, it usually indicates the following situations: a. the arrangement of milling cutters on the milling drum is irregular; b: Single milling is too deep; c: Using unsuitable milling cutter to remove different types of road surface; d: The strength of milling surface is too high
7. Before each operation, check the belt tightness. The tightness of the new belt should be readjusted after 4 hours of operation. Proper belt tightness must be maintained in order to transfer the output horsepower of the engine to the milling drum. If the belt is too tight, it will be easy to wear and shorten the service life of the bearing, such as broken marks, broken belt, broken belt and so on
1. One part is daily technical maintenance, that is, the operator can reasonably keep, daily overhaul, regular maintenance and correct operation and use of machines and tools in the process of use, which can prolong the service life of machines and tools and improve the application effect of machines and tools
2. The other part is periodic technical maintenance, that is, the maintenance content that cannot be solved by the operator's own conditions and means, such as the repair or replacement repair of the main parts of the machine, the overhaul and inspection adjustment after a certain period of use, must go to the maintenance point designated by the special manufacturer for professional repair
3. Finally, the technical maintenance of long-term parking. Because the paver is different from other machinery, especially in Qinghai, it is basically not used in winter, so maintenance should also be carried out
