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

    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 mixing arms of the concrete mixer?
Concrete mixer parts often due to operational mistakes and equipment damage, we should know that the correct use of Yantai mixer parts, mixing arm not only can complete the "workload" on time, but also to extend the service life
Q:What are the principles, performances and uses of the commonly used construction machinery equipment?
2.: Principle: loader loader work, powered by a flywheel of the diesel engine to the hydraulic torque converter, the torque converter will drive to the gearbox, and before and after the output flange of the gearbox, the power output of the gearbox after the transmission shaft are respectively transmitted to the front and back drive axle to drive the wheels forward. Performance: 1) Central articulated frame, turning radius is small, flexible and convenient operation in narrow space; 2) using hydraulic mechanical transmission, according to the size of the external resistance and automatic stepless speed change, which can make full use of engine power, and improve the maneuverability, simplifies the loader operation. Is to protect the transmission parts and engine; 3) adopts full hydraulic steering, power shift transmission, hydraulic or flexible manipulation, portable and flexible machine; 4) stable and reliable operation; wide use of low-pressure off-road tires, rear axle swing, with good cross-country performance and through the performance by 5); gas cap oil disc brake system and brake foot up, emergency braking system, the braking performance is safe and reliable; 6) with advanced structure and bright cab. The air conditioning system operates more comfortably. Uses: loaders are mainly used for shovel, loading, unloading, transport of soil and stone a kind of bulk materials, rock and hard soil can also be slightly shovel operations.
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 are the world famous mechanical equipment exhibition?
3, the French international civil engineering and Construction Machinery Exhibition (INTERMAT) the European Construction Committee (CECE), founded in 1988, tenth in 2015, is one of the three famous exhibition of world engineering machinery and construction machinery field, three years. France INTERMAT exhibition exhibits covering mining machinery, earthmoving machinery, concrete machinery, lifting machinery, pavement and compaction machinery, piling machinery, industrial vehicles, pneumatic tools, drilling machinery, building materials machinery, mining machinery and other engineering and construction machinery and spare parts industry. Paris International Construction Machinery Exhibition in Europe - the Middle East - Africa (EMEA) region has a unique position.
Q:Building materials, equipment, components and fittings products must have "three certificates" is what cards?
Product quality certification, also known as product certification, internationally known as qualified certification. According to the 1991 implementation of the "people's Republic of China Quality Certification Management Regulations", the product quality certification is based on the product standard and relevant technical requirements, the certification institution confirmed by the certification and certification marks to prove that a particular product is in conformity with the relevant standards and technical requirements of the corresponding activities.
Q:How are the machine parts stacked?
Then there is a point to note, that is, from there to get used, must be put back where, so that will be organized, all things are owned by you, it will not mess.
Q:What is a door rack for a construction site? How high is it generally?
Door scaffolding has not yet unified design and product standards, the products of different specifications, quality is inconsistent. Not only for construction units to use and management of great difficulties, is not conducive to the promotion of applications, but also to the construction safety risks. Therefore, it is necessary to organize and issue a unified standard for door scaffolding
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:What measures can effectively reduce the construction accident rate?
Hefei construction workers training _ fail safe design: in the part of the system, equipment malfunction or damage, can also ensure the safety of safety and technical measures known as fault - Safety Design in a certain period of time (fail-safe). Generally speaking, through careful technical design, the system and equipment are in a low energy state when the fault occurs, thus preventing the unexpected release of energy. For example, a fuse in an electrical system is a typical fault - Safety Design; when the system is overloaded, the fuse is fused and the circuit is disconnected to ensure safety. Although the fail safe design is an effective measure of safe technology, but considering the fail safe design itself may not work due to failure, so the choice of safety technical measures should not give priority to the use of.
