Whether it is the tractor, combine harvester, agricultural and sideline product processing machinery, or the plow, harrow, and planter, the modern agricultural machinery compared with agricultural machinery 30 years ago, a great major development is the extensive application of hydraulic technology and advanced manufacturing technology.
Early traction combine harvesters used mechanical transmission, which was slow in speed, low in efficiency and poor in harvest quality. With the development of hydraulic technology, the combine harvester first adopted hydraulic transmission in the control system. Due to the feature of hydraulic technology infinitely variable speed, the hydraulic control handle on the bridge can change the transmission ratio of the pulley to realize the infinitely variable speed.
When using a traditional gearbox to shift gears, the clutch must be pedaled to interrupt the transmitted power. If the tractor operates at low speed and high traction, cutting off the power transmission means stopping and restarting the tractor, which will affect the productivity of the unit.
At present, the hydraulic suspension has become a widely used control device to replace manpower and an indispensable part of large, medium and small tractors. Suspension methods have also developed from rear suspension to front suspension, side suspension and wheel suspension, and automatic hooking mechanisms have appeared.
There are many kinds of farm tools. Whether it is the turning of the two-way plow, the adjustment of the angle of the rake blade, or the folding of wide-width machines, most of them are hydraulically driven. Therefore, the driver can use tractor hydraulic power according to actual working conditions. The quick connector can be used to remotely control the working state of the machine tool, and make full use of the advantages of hydraulic control, so that the work efficiency is greatly improved.
The hydraulic walking drive uses a high-pressure liquid drive motor to drive the walking wheels, which includes two kinds of high-speed scheme and low-speed scheme. The high-speed scheme is that the variable pump drives the high-speed fixed motor, and then the walking wheels are driven by the gearbox. The low-speed scheme is that the variable pump directly drives the walking wheels through the variable motor.
The steering device adopting the full hydraulic steering gear cancels the mechanical connection between the steering wheel and the steering wheel, and performs remote control through hydraulic oil pipes.
In addition to the extensive application of hydraulic technology on agricultural machinery, hydraulic technology is also applied in engineering machinery, metallurgical machinery, and automobile manufacturing. Construction machinery is the most widely used field of hydraulic products. Every year, many hydraulic components are produced for excavators, road machinery, construction machinery, piling machinery, mixer trucks, etc.
Automobiles and motorcycles require a large number of power steering pumps. Automatic transmissions also require hydraulic control components, various types of seals and pneumatic components. Automobile manufacturing equipment requires various pumps, hydraulic solenoid valves, air valves, air source processing devices, various cylinder proportional valves, gear pumps for trucks, oil cylinders, and control valves.
In general, the application fields of hydraulic components are very wide. The hydraulic transmission system and pneumatic system components produced by JAZZY are of high quality, welcome to consult.
