Flour machine is a wheat processing machine that relies on the external power, such as the power produced by the motor, grinding the wheat into small particles and to separate the flour particles of different sizes by adjusting the size of the sieve holes.Flour mill is mainly divided into full automatic flour mill, stone flour mill, Corn Flour Machine, small flour mill and large flour mill.

As the domestic automobile industry matures, all domestic laws and standards are also aligned with European and American countries. The new national standard GB7258-2012 “Technical Conditions for Operational Safety of Motor Vehicles†as implemented from September 1, 2012 stipulates: “Trucks and dangerous goods carriers exceeding 12 tons will be forced to install retarders or other auxiliary braking devicesâ€. This again highlights the importance that the state attaches to the safety of transportation and, in turn, drives a broad space for the domestic retarder market. In addition, the state attaches importance to safe production, and energy-saving and emission-reduction is also the primary social task to be implemented in the whole society. In particular, the national IV emission standard that is fully implemented after July 1, 2013 will further enhance the level of automobile production. It also provides opportunities for the development of retarders.
Looking at the domestic retarder market, the mainstream is divided into two major types of products: hydraulic operation and eddy current operation. Among them, it is not difficult to find Shaanxi Fast Group is focusing on the current opportunities and efforts. In the beginning of 2013, Fast added a new phase-one project for the annual production of 4,000 hydraulic retarders. The first phase of the project has been successfully completed and put into mass production. This marks the new generation of hydraulic retarder products independently developed by Fast and challenges foreign companies. In the domestic market for heavy-duty brakes, the monopoly position.
The reporter called the Fast Sales Hotline and learned that the new Fast Reactor was developed for efficient deceleration braking of medium and heavy vehicles. The whole series of products can be matched with Fast 6-speed to 20-speed transmission, and its maximum retarding torque can reach 4000N·m. The reporter then read the data and learned that in 2012, Fast developed the FHB320A parallel hydraulic retarder on the basis of the FH400B series hydraulic retarder and achieved mass production, thereby realizing the parallel and parallel hydraulic power. The retarder fully covers the product strength of all customers and trucks with a capacity of over 12 tons.
As an auxiliary brake device, the hydraulic retarder uses the turbine oil in the working chamber as a medium, and uses the stator to counteract the force generated by the agitated oil of the rotor to achieve the braking effect and brake the vehicle drive shaft. The kinetic energy generated by the brake is converted into heat energy, and the heat energy of the oil is transferred to the circulating water through the heat exchanger, and the entire vehicle water circulation system is used to achieve the heat dissipation of the cycle, so that it can be used continuously.
Although there are various advantages of the retarder, it is also necessary to match the model at the same time as the installation. For example, the cooling capacity of the vehicle has a great influence on the continuous operation of the retarder. In addition to meeting the engine cooling, it also has to take up the heat generated when the retarder works, and the retarder is connected in series with the engine to ensure the cooling of the tank. Water cools the engine, cools the retarder, and then returns to the water tank to ensure the safety of the engine.
The cooling capacity of the vehicle mainly depends on the size of the cooling water tank, the flow rate of the water pump and the fan power. This requires the configuration of the FAST hydraulic retarder to take care of the configuration of the above aspects and use the most appropriate Water tanks, pumps and fans, and in the driver's operation, should pay attention to the reasonable speed of the engine, the company is now required to continue to use the retarder brake, the engine speed should be maintained at 1600R / MIN or more, in order to enhance the water flow rate, improve heat dissipation .
Therefore, the current choice of the engine is more than 375 horsepower, and it is the best match to retrofit the engine with more than 10 liters of the engine. Smaller vehicles with smaller tank sizes, pumps, and fans can also be fitted with retarders, or tanks, pumps, etc. can be used to expand the range of retrofit models.
