Storage capacity of machine utilization and yard of the post and not give full play to the yard for homework, nearly blind.
The hump of the cantilever belt conveyer is equipped with two rows of three groups of sealed supporting roller support groups. The coal is not easy to clean, and the supporting roller is highly stressed, which is easy to damage and cause the tear of the conveyor belt.
The limiting device is mechanical, easy to fail, and often produces misoperation.
Drive motor leaf coupler God NJ drive shaft planetary gear reducer of bucket wheel leaf bucket wheel body.
The motor is connected with the coupling device by key. It is difficult to assemble and disassemble. The transmission shaft often damages the planetary gear reducer's primary bevel gear due to insufficient oil supply, often damaged, overload protection is not reliable, often overloaded, and there are many mechanical damage accidents.
Two the transformation content is controlled by the OMRON type instead of relay in Japan, which simplifies the control line, reduces the connection terminals and improves the reliability of the electrical control.
The original nine electrical cabinets are combined into four, that is, power cabinet, frequency converter cabinet and control cabinet. Centralized control is realized, which is not only convenient and neat, but also reduces the breakdown point. It is easy to troubleshoot and repair conveniently.
The safety slide conductor of the power supply system is selected.
Because of the length of the walking operation of the bucket wheel stacker reclaimer, the two end power supply voltage compensation method is adopted.
After the transformation, the power supply reliability is improved, the slipper wire is in good contact, long life and no electricity leakage.
A Fuji type inverter is used to drive a one w AC motor as a rotating drive system to ensure the stability of rotation.
A Fuji mobile inverter is used to set up two frequency control four sets of W motors. Each traveling trolley is composed of one motor and a single input planetary differential speed reducer. The total installed capacity is reduced from w to simplified walking mechanism.
Increase the angle of rotation.
We take the change of bucket wheel stacker operation mode, disengaged from the tail car is removed from the main cable support measures to change the main cable to the rotation angle, to improve the ability of soil, effective coal storage yard.
The cantilever belt roller to work a single row of single roller group structure, to solve the roller is easy to plug coal stuck problems will roller bottom sealing structure for open type structure, and the welding plate at the end, in order to solve the problem of hump is not easy to clean up the hump by degrees to degrees of corrosion thrust roller, in order to solve the hump of excessive force, tearing up the belt problem.
A reflective infrared photoelectric limiting switch to ensure the safety and sensitivity of the limiting device.
The bucket wheel drive system for hydraulic drive, has less fault judge, stable operation, energy conservation and so on, because of the use of imported hydraulic components, Paomaodilou problem basically no planetary gear damage situation also reduced.
Three economic benefits of technical performance can be improved, each bucket wheel stacker coal handling efficiency and improve the fault rate dropped by the motor and inverter capacity decreased, reduce power consumption, each bucket wheel reclaimer operation work saving 12 tons of thousands of simplified structure, reliability improvement, each bucket wheel stacker maintenance time is reduced by about.
Increase the rotation angle, the freight yard stockpiling capacity increased million tons per year.
The cost of maintenance is greatly reduced, and two bucket wheel stacker reclaimer saves ten thousand years.
Reduce the auxiliary operation of four bulldozers loader, and save a lot of expenses.
The life of the rotating support is prolonged, and a rotating support requires ten thousand yuan.
The port authority of Xuzhou science and technology communication address in Jiangsu province Xuzhou Huaihai Road West Series words processing performance of condensed water and a pressure of several impurities.
Zhou Yizhi our company is a large non-ferrous product processing enterprise, the need to use a large number of compressed air, through the removal of oil removal of nitrogen mechanism nitrogen.
In order to clear the condensed water and impurities in compressed air, a gas liquid separator is installed on the compressed air main road to carry out gas liquid separation, and the impurity impurities are separated by automatic drainage.
Because the air humidity is big, the spring and autumn season of compressed air in the water too, and the influence caused by debris, automatic drain is often blocked, so a lot of water control spread from the gas-liquid separator to dry desiccant failure, to prepare the gas nitrogen machine required (Bo dew point temperature influence of water production.
The electric appliance is used to control the discharge of condensate and impurities, and the problem is solved.
We installed a two position and two way electromagnetic cutting (direct connection) in the outlet of the gas-liquid separator, that is, the original automatic drain. We used time relay to control the interval time between the two emissions and the emission time of each time. The two time can be selected at 5.
In this way, the length of interval time and discharge time can be set according to the specific circumstances of the environment, so as to achieve the purpose of discharging condensate and impurities in one time.
After improvement, the dryer work is very stable, the quality of the gas source is improved, the nitrogen making machine works well, and the failure rate is zero for more than two months.
