Product Description:



1 Characteristic

HRCV slewing controller is a hoisting slewing controller developed by our company according to service condition of customer.

The main technical feature as follows:

(1) This product combined the controller and thyristor module,the connection of the users is simple and easy.Prevent the damage of the controller and thyristor module caused by mis-wiring of the customer.

(2) Realize the best optimization of AC voltage control curve and DC voltage control curve.

(3) With the function of inching during operation, realize the accuracy.

(4) The electronic components adopt the imported industrial grade chip, on the control panel directly with power supply and direction indicator light.

(5) Adopt the coating treatment on the printed circuit board,enhance the dust prevention and anti-condensation capacity of the circuit board.

2 Operation condition

(1) Application of environment condition

    working temperature: -10  °C~ + 40  °C

    relative humiduty: maximum 50% (when the temperature is 40  °C)

                                   maximum 95% (when the temperature is 20  °C)

(2) Grid quality

    voltage continuously fluctuate no more than  ±10%

(3) Rated voltage

     50HZ/60HZ, AC380V/440V three-phase voltage

     50HZ/60HZ, AC48V/55V voltage by one phase

3 Output parameter

(1) voltage output

     three-phase voltage output: 50HZ AC140V~380V;

     eddy current voltage: DCOV~20V

(2) electricity output

     according to the size of the rotary engine,electricity output choose 106A,162A,273A and so on.

Q:What are the details of construction machinery parts in sand casting?
(3) equipped with fittings, installation type air switch and air shower room installed in the furnace. (2) all kinds of vehicle tracks, transmitters, differential pressure and buttons are all materials other than the equipment body. (3) rotating filter network circulating water system for equipment, induction phase shifter, manhole and other various products embedded parts, clean bench, meter, scientific research and other functions of the machine, and pipeline safety device, railing, peep hole, ventilation air heater (1):
Q:What are the sectors of machine building and parts processing?
1., industry generally refers to its production of similar products, or with the same process, or to provide similar labor services division of economic activities, categories.
Q:What is the use of spare parts prices in Chinese market by foreign companies?
But there is always somebody to ask, just like a college paper, where everyone can read or keep secrets, but collecting them and sending them to foreigners is a sign of treason
Q:China mechanical net
There are mechanical product development and design, mechanical equipment transformation, mechanical equipment maintenance, data inquiries, standard inquiries, mechanical professional translation, mechanical CAD and other mechanical and technical services.
Q:What kind of electrical equipment do you have? What are the main components of each device?
1 、 electrical equipment part of electrical equipment mainly refers to: substation and distribution of power equipment and local scattered power, lighting distribution box. Such as: dry type power transformer, high voltage and low voltage power distribution cabinet, control the use of DC cabinet (with battery), standby uninterruptible power supply cabinet, lighting distribution box, power distribution box (cabinet), power factor capacitor compensation cabinet and standby diesel generator etc.. The utility model is characterized in that the rated voltage is mostly 10KV380V/220V by the combination of independent functional electric components, and the voltage is only 24V or 12V in the control system only.
Q:What are the safety protection equipment, machinery and equipment, construction machinery and accessories for construction enterprises?
Different types of work, security appliances are not the same. For buildings, the main safety helmets, safety nets, safety belts (San Bao), etc., for electrical operators, mainly insulated shoes, insulating gloves, insulation rod, insulation table, etc.
Q:Construction Engineering, moving equipment and stationary equipment, respectively
1, moving equipment refers to the rotating device driven by the drive (that is, energy consumption of equipment), such as pumps, compressors, fans, etc., the energy can be electric power, pneumatic power, steam power, etc..
Q:What is the difference and connection between equipment manufacturing and machine building?
When our company went to the training center of the Department of industrial engineering of Tsinghua University, the professor of Qinghua University told us about it. Equipment manufacturing industry is a general term for the equipment provided for the national economy and national security
Q:Where was the construction machinery conference held in 2015?
2015 Bada international construction machinery exhibition, exhibition information time: June 5, 2015 (Friday) - 7 day (Sunday) location: Shandong Bada international engineering machinery City Theme: cooperation, win-win, innovation, development, guidance: National Quality Supervision and inspection center of engineering machinery, Shandong Machinery Industry Association, Shandong province transportation and Logistics Association Shandong, Shandong Jiaotong University, Shandong Institute of road, economic development zone of Qihe Province
Q:The building electrical iron pipe and the pipe line fixing member connected to what is called, what is called the iron pipe and the 86 fixed part of tin
Pipe or direct protection, construction of special operation personnel of construction electrician training materials, focus on the "construction of special operations personnel management regulations", "construction of special operations personnel safety technology assessment program (Trial)", "construction of special operations personnel safety operation skills examination standard (Trial)" and other relevant provisions safety, technical knowledge and skills to master for construction electricians were explained, the book has 10 chapters, including: basic knowledge, common low-voltage electrical appliances and Motor City, power supply and grounding earthing protection system.
