Preventive pursuit of balanced braking is that the brake balance of the wheels when the vehicle is braking is consistent. Both front wheels overlap. Direction deviation can be prevented, and the two rear wheels coincide. Can prevent the body side slip. When a car brakes on ice, snow, rain, and wet roads, the detachment and tail will not be able to control the vehicle to varying degrees. If the two situations occur at the same time, normal road braking will also lose complete control of the vehicle. Heavy transport vehicles once out of control, the consequences are even more serious. Therefore, in order to avoid the occurrence of major traffic accidents and ensure the safety of people's lives and property, heavy transport vehicles resolutely eliminate all "unbalanced" car brakes. The brakes move the tail.

Under the working voltage, it works according to the working mechanism, load duration and cycle of the tractor. When the brake reaches a thermal steady state, the temperature rise of the brake coil is measured. The measurement method adopts GB 755-2008 "Rotating Electrical Machine Rating and Performance" 8.6.2 Resistance Method for measurement and calculation. Brake coil temperature rise shall not exceed 80K when insulation class B is used. When insulation class F is used, the temperature rise of the brake coil shall not exceed 105K. For the brake with the exposed surface temperature over 6(TC), add the warning display to prevent scald.

What should be noted when checking the brake coil control circuit?
19 Jan,2022
Carefully check the electrical schematic and wiring diagram, and carefully analyze the number and mutual independence of electrical devices in the control circuit. It can be seen that XC, SC and YXC are not independent, but mutually controlling relationships.

Production Difficulties and Control of High Toughness Ductile Iron
22 Dec,2021
High toughness ductile iron is a kind of gray cast iron with excellent mechanical properties. The molten iron is solidified to form spherical graphite. The strength and toughness of high-toughness ductile iron are higher than other cast irons. Generally, before pouring, a small amount of spheroidizer (usually magnesium, rare earth magnesium alloy or rare earth alloy containing cerium) and inoculant) are added to the molten iron, usually ferrosilicon), sometimes replacing cast steel and malleable cast iron in the machinery manufacturing industry. So, let's understand the difficulties and control of high toughness ductile iron production together!

How to Smelt Cast High Toughness Ductile Iron
13 Dec,2021
Casting high toughness ductile iron castings and shortening the supply cycle is the direction that enterprises strive to pursue in the manufacturing process. It is to reduce heat treatment links and save intermediate transportation costs on the basis of meeting special performance requirements. Especially in the current fierce market competition Under the environment, the production cost of the enterprise has been effectively reduced, take QT600-10 material as an example to introduce its control method, then, let's learn how to melt cast high toughness ductile iron!
