Construction Machinery Industry-Asphalt Pavers
The use of full hydraulic system technology to achieve walking, spiral, vibration and other closed hydraulic system. The whole machine can realize constant speed control, material level control, fault intelligent diagnosis and other functions. The walking system is driven independently by double jumping and double motors with high control precision, with stable driving and smooth steering. The plunger variable pump, plunger quantitative motor, cycloid motor, walking reducer, shaft output rotary reducer, etc. constitute a fully hydraulic walking system, material dividing system, vibrating system and feeding system.
Construction machinery industry-small road roller
By controlling the hydrostatic power unit composed of variable pump and quantitative motor, it is convenient to realize the forward and backward of the small roller.
Construction machinery industry-road roller
Full hydraulic drive system, dual-frequency dual-amplitude hydraulic vibration system, manual servo plunger variable pump, plunger quantitative motor control walking, electronically controlled plunger variable pump, plunger quantitative motor control to achieve dual-frequency vibration function.
Special Vehicle Industry-Fire Truck
The hydraulic system of the vehicle adopts a load-sensitive pump and two sets of PVG multi-way valves to realize the action of each oil cylinder. The PVG multi-way valves adopt high-precision electric proportional control to control the actions of the upper arm frame and the driving outrigger respectively, and realize the interlocking relationship between hydraulic pressure and electrical equipment to realize performance operation. PLUS 1 microcontroller and display are adopted for the whole electrical control system. When the panel operation system fails, the display operation system can be adopted, prevent the whole vehicle from losing control in emergency, realize automatic reversing of propeller fan blades, solve the problem of positive and negative pressure conversion, adopt automatic control of liquid medicine variable frequency pump according to water flow and set medicine ratio, realize automatic mixing of medicine, reduce environmental pollution, realize the switching of acid liquid and alkali liquid decontamination through one-key switching, solve the compatibility of chemical accident treatment with different acidity and alkalinity, enhance the versatility of the whole vehicle, and set up the maintenance interface through HMI display, it makes the maintenance of the whole vehicle simple.
Construction Machinery Industry-Skid Steer Loader
Wheel skid steer loader double plunger variable pump double cycloid motor composed of closed walking drive system, gear pump, sliding special multi-way valve and other components of the working hydraulic system, crawler skid steer loader double plunger variable pump, motor, reducer integrated drive system.
Construction machinery industry-hydrostatic loader
The electronically controlled variable plunger pump detects the engine speed through the speed sensor. After the controller is set, the displacement of the variable pump changes with the change of the engine speed, and the automatic control of vehicle walking is realized. According to the walking transmission system, different plunger motors are configured., Cycloid motors and other driving walking systems, gear pumps, priority valves, steering gears, multi-way valves, etc. realize the steering system and working system of hydrostatic loaders.
Automotive Manufacturing-Bus Air Cooled
The fan drive is composed of an electric proportional pressure variable plunger pump and a quantitative gear motor. The controller collects the engine signal to form a continuously variable speed for the entire fan drive system, so as to ensure that the engine can get good cooling in different working conditions and different environments effect.
Airport industry-container, pallet loader
The hydraulic system can be divided into an open working system and a full hydraulic automatic control system. According to the drive type, it is divided into single-circuit and dual-circuit braking to ensure the controllability of the vehicle.
Oil industry-Fracturing trucks
The hydraulic air-cooled drive can be controlled by H1P pump FDC, matched with closed fan drive, and the forward and reverse rotation of the fan motor can be realized. Danfoss's controller is put on the board to replace the enlarged version of the original Parker, with lower price and high reliability, and gradually replace the original controller.
Oil industry-oilfield logging trucks
Electronically controlled variable plunger pump, electronically controlled variable plunger motor, two-speed reducer, electronic control handle and other components of the closed hydraulic drum drive system, convenient to achieve the logging car drum lifting, down and other functions.
Airport industry-snow removal vehicles
The closed hydraulic system drive system realizes the anti-skid of the vehicle. The plan of the open pump high-precision valve group can realize the coordinated work of rolling brush, material distribution and spreading. The closed fan system realizes the most reasonable power and can also realize the low temperature cold start function.
Machinery Industry-Smoke Exhaust Fire Engine
The crawler type open walking system adopts the valve control walking of the open plunger pump, matches the accurate walking valve group, matches the working valve group together, and the closed fan electric control drive system, which can realize the ready driving speed of the fan, the closed fan drive system, the electric control variable pump can make the air volume be adjusted arbitrarily according to the needs, the efficiency is high and the voice is small, the open load sensitive system controls the crawler walking, reduces the deviation, and adopts PIUS 1 microcontroller and displays, realize the control of multiple operating systems. According to different working conditions, realize the automatic reversing of the left and right water mist fans. According to different fire conditions, realize the stepless smooth speed regulation of the exhaust fan. The display operating system is used as an emergency system to prevent emergency situations. The vehicle is out of control. The reliability of the vehicle system is guaranteed, and the high-performance controller ensures the stability and high reliability of the vehicle control system.
