2.2 hydraulic brakeHydraulic brake is essentially a turbine, and the fixed pump drive speed fluid flow resistance torque tremendous, make the belt conveyor hydraulic coupling run slow. It can adjust charging liquid to change the size of the braking torque, by belt conveyor controllable braking functions. Mainly consists of hydraulic turbine pumps tired, coupled with hydraulic brake cooling control system.When the belt conveyor during normal operation within the brake charging liquid, not drive motor drive pump operation, and will need brake fluid, according to the input into the liquid filling how to adjust the volume of the size of the braking torque. Usually used for oil, but due to the fluid in a very short time to put the braking energy belt conveyor, therefore consume all the oil temperature rising sharply, so will oil must adopt circulatory system and heat. It has the braking torque, can adjust the advantages, but for pumping equipment, thus with large volume of equipment.Hydraulic brake braking torque and brake rurning speed is proportional to the general installation on the speed reducer, high-speed shaft. Due to the braking torque in brake process adjustable very applicable by belt conveyor. The hydraulic brake could not put belt brake to zero velocity, when the pump 400r/min speed below must be installed with other types of brake, satisfy the requirements for cars. But because of equipment, the volume of belt conveyor, scalable cannot install and use.230 hydraulic brakeHydraulic brake into hydraulic pressure braking and hydraulic speed brake.1) hydraulic pressure brakeIts principle of work is to connect volumetric pump in the belt conveyor by host, drag. When braking energy will be transformed, pump, hydraulic pump outlet pressure by adjusting the size can adjust the size of the braking torque, so as to achieve the purpose of belt conveyor braking. Hydraulic pressure brake pressure after the confirmation, the system will output a host of speed changing with constant braking torque. Its main advantage is the braking torque is proportional to the set pressure, and it can be independent, rotational speed brake to zero without set machinery.2) hydraulic speed brakeThis device, the pump with host hydraulic pumps flow when change, can change the speed of the belt conveyor, so as to realize the brake control brake.Hydraulic brake control through hydraulic or flow, can effectively to achieve by belt conveyor braking deceleration. For high-power by belt conveyor, generally USES the brake pressure big flow variable piston pump, when braking belt conveyor, emissions to the largest, and belt conveyor during normal operation, capacity to minimum. Due to a long time in the pump operation, quick wear, short life, in the braking process, a large number of braking heat away from the hydraulic oil and water, increase the heat radiator with system. When the oil temperature is exorbitant, hydraulic components, oil due to the failure of the circular motion and large flow, easy temperature changes, further influence the reliability of hydraulic control system, at the same time, when the belt conveyor, because for pump and hydraulic system is leaking and must be specially added for hydraulic brake rod by car.2.4 mucus controllable brakeFluid sticky controllable brake principle and liquid viscous controllable soft starter. It is used in the liquid viscous friction friction torque transfer. To realize the braking performance of belt conveyor, fluid sticky controllable braking device adopts often closed structure. When ZhuDongZhou driven active friction slices rotates, because move, from the frictional chips that winner, between pieces from sample.the friction. Change control of hydraulic oil cylinder size, can adjust the piece, from the frictional force between the pressure, and further change from active friction between the friction torque sample.the, thus realizing the brake technology of belt conveyor. In the process of braking, braking torque with oil film clearance decreases with the braking speed, but decreases. So in the braking process, should constantly decrease oil film can ensure certain clearance, braking torque.Fluid sticky controllable braking device structure is simple: to provide adjustable, no impact on the smooth, the braking torque, Can use a hydraulic station platform braking, Belt conveyor overload can achieve automatic overload protection function, Use safe, reliable, and small braking torque, has good effect, The brake fluid sticky controllable, from the frictional are working in viscosity lubricating oil, it is through to heat, cool, cool water can save save operating costs. Fluid sticky controllable brake is now better braking device, especially suitable for long distance, high-power by belt conveyor.

In 2.2 fluid strength arresting gear fluid strength brake essence is a turbine wheel is fixed, and produces the huge moment of resistance to the pump pulley impetus high speed liquid flow, causes the belt conveyer to decelerate the movement the fluid strength coupler.It may through adjust the sufficient liquid volume to change the braking moment the size, under the realization transports the belt conveyer the controllable brake function.Mainly by the belt pump tired, the turbine wheel fluid strength brake coupler and the hydraulic pressure cooling control system is composed. When belt conveyer normal work in the brake not the sufficient fluid, the pump pulley revolves by the drive motor impetus, needs to apply the brake when inputs the liquid, according to imitates enters the liquid quantity how many to adjust its braking moment the size.Usually uses the liquid will be the oil, but because needs to consume in the very short stop time the belt conveyer complete kinetic energy, therefore the oil temperature suddenly will rise inevitably, therefore the oil duct will have to use the circulatory system in order to help the radiation.It has the braking moment to be big, may adjust merit, because but has equipment and so on pumping station, therefore the equipment volume is big. Fluid strength brake braking moment and the brake impeller rotational speed square is proportional, installs generally on the reduction gear high speed axis.Because braking moment in brake process adjustable, therefore is suitable extremely in under transports the belt conveyer.Also because the fluid strength brake not impossible to apply the brake to the zero fast the belt conveyer, when the pump pulley speed is lower than 400r/min, must install other types the arresting gear with it coordination, decides the vehicle request satisfiedly.Because but the equipment volume is big, is unable on the expandable belt conveyer to install the use. 2.3 hydromatic brake hydraulic brake divides into the hydraulic pressure accent to press the brake and the hydraulic pressure velocity modulation brake. 1) the hydraulic pressure adjusts the suppressed motion its principle of work is the volume type oil pump connection on the belt conveyer, drives by the main engine.When applies the brake, the oil pump transforms the mechanical energy into the hydraulic pressure energy, may adjust the braking moment through the adjustment pump outlet pressure size the size, thus realization belt type conveyer brake goal.After the hydraulic pressure accent presses the arresting gear the pressure determination, the system will output one not along with the main engine rotational speed change constant braking moment.Its main merit is the braking moment in proportion to adjusts the constant pressure strength, moreover it has nothing to do with with the rotational speed, therefore may apply the brake the rotational speed to the zero not to need to suppose the mechanical floodgate. 2) hydraulic pressure velocity modulation brake this equipment oil pump along with main engine rotation, when change hydraulic pressure oil pump current capacity, may change the belt conveyer the rotational speed, thus realization arresting gear controllable brake. The hydromatic brake through the control flowing tubing head pressure or the current capacity, may effectively transport the belt conveyer realization brake deceleration to under.Transports the belt conveyer regarding the high efficiency under the brake, uses the high-pressured great current capacity variable ram pump generally, when brake belt type conveyer, the displacement moves in a big way, when belt conveyer normal operation, the displacement moves slightly.Because the hydraulic pump long time is at the high-speed operation condition, wears quickly, the life is short, in the brake process, the massive brakes carries off hotly by the hydraulic fluid, and radiated after the liquid cooled radiator, increases has set up as an attachment the system.When the oil temperature excessively is high, the hydraulic pressure part easy to appear the breakdown, simultaneously the fat liquor as a result of the great current capacity circulating motion and the temperature change, very easy to deteriorate, further affects the hydraulic control system the reliability, when simultaneously the belt conveyer decides the vehicle hour, as a result of the hydraulic pump and hydraulic system divulging, must add the hydraulic pressure throwout lever brake to decide the vehicle specially. 2.4 mucilage controllable arresting gear fluid sticks the controllable arresting gear principle of work and the liquid coherency controllable soft start equipment is same.It is uses the friction disk in the coherent liquid friction force carry-over moment.In order to realize the belt conveyer each braking quality request, the fluid sticks the controllable arresting gear to use often the closed structure.When driveshaft impetus initiative friction disk revolving, because the driven friction disk is motionless, causes between the new owner, the driven friction disk to have the friction force.In the change control cylinder flowing tubing head pressure size, may adjust between the host, the driven friction disk compaction strength, further changes the initiative friction disk and the driven friction disk friction moment, thus realization belt type conveyer each brake specification.In the brake process, the braking moment reduces along with the oil clearance increases, reduces along with the brake speed reduces.Therefore in the brake process, should reduce the oil clearance unceasingly, can guarantee certain braking moment.The fluid sticks the controllable arresting gear structure to be simple: Can provide adjustable, smooth, the non-impact braking moment; May use a hydraulic pressure station to carry on the multi-Taiwan brake; The belt conveyer overloads when can realize the automatic over-load protection function; Uses safely reliable, the braking moment attacks slightly, has the good use effect; The fluid sticks the controllable arresting gear the host, the driven friction disk all works in the coherent lubricating oil, it is carries on cooling through the lubricating oil to radiate, may omit the cooling water used, has saved the operating cost.The fluid sticks the controllable arresting gear is at present good arresting gear, suits specially applies in the long distance, high efficiency under transports on the belt conveyer.
