With the strong support of the power supply department of Mudanjiang City in Heilongjiang Province, the first batch of gas-electric hybrid buses in Mudanjiang City of Heilongjiang will be put into operation.
In order to develop the urban economy and achieve energy conservation and emission reduction, the first batch of 44 plug-in gas-electric hybrid buses in Mudanjiang City will be put into operation before the end of the year. The biggest highlight of the new energy and environmental protection bus is the “LNG-electric hybrid busâ€. The vehicle starts at the stage of electric drive. After reaching a certain speed, it is converted into natural gas to provide power. After the vehicle is braked, the motor is charged by the energy recovery device and operated every day. After the end, the vehicle is centrally charged at the charging station, and each vehicle needs to charge about 1000 kWh per month.
According to reports, the hybrid bus based on this design concept is more suitable for the cold weather in northern China, and the pollution emission of traditional buses is reduced by 70%-74%, realizing energy saving and emission reduction. The electric vehicle charging station, which is the supporting project of the project, is equipped with 12 fixed charging piles and 2 mobile charging piles. Each charging pile is equipped with 4 charging plugs. In response to the electricity use of the project, Mudanjiang Power Supply Company conducted a market research on the project's electricity demand. In the project power approval procedures, the power flow process will be further simplified, and a “green power channel†will be opened to handle the customer's capacity at the fastest speed, increasing the user equipment capacity from 80 kV to 200 kVA. , to meet the project's electricity demand.
In mine production, the essential equipment, mine hoister & crane, includes shaft and incline hoists which is treated as the "throat" of the mine. It is responsible for putting down and up of ore, barren rocks, equipment, materials and labors.
First, it takes lots of time in faults determine as there are so many electromagnetic relays, and the failure rate is very high in long time operation, which not only need a high cost in maintenance but also affect the ore production; Second, low hoist automation degree, loud operation noise, high temperature, high labor intensity and the hoist driver get tired easily; Third, in continuous heavy loads lifting in low speed, the resistance get overheat easily, then cause resistance connection wire burning and high energy waste; The last but not limited on these point, the step speed regulation cause huge mechanical impact on the steel wire rope and speed reducer.
