Product Description:

1 Application

  RCV slewing controller is a tower crane hoisting slewing controller device combined of three-phase AC variable voltage control and eddy current speed control.

 After connection with the vortex torque motor and reduction box,through the potentiometer voltage instruction on the operation panel,to control the thyristor trigger conduction abgle of three-phase AC current and eddy current, so that control the rotation speed of eddy current torque motor,realize the smooth start,operation and stop of the tower crane slewing system.

Q:What are the principles, performances and uses of the commonly used construction machinery equipment?
1.: concrete pump principle: concrete pump driven by motor pump system, the conveying capacity of constant power control of hydraulic system of concrete pump automatic control, manual control can also be used to select the concrete delivery volume. Performance: 1. using the hydraulic system of double pump double open circuit, the main pump valve swing circuit and S circuit are separate for fault diagnosis and removal; 2. pumping hydraulic circuit adopts the main valve pilot pressure control; 3. hydraulic system has safe relief protection, while the main pumping system overpressure, oil pump automatic pressure cutting off; 4. switching circuit with constant voltage supply with the energy storage device, so as to guarantee reliable swayingforce large and have the advantages of energy saving effect; 5. pumps and valves are used continuously, the world famous brand is more reasonable and more reliable and easily realized commodity concrete transport quantity adjustment; 6. hydraulic pipeline with cone seal pipe joint sealing material; 7. pumping circuit adopts a valve block mode of high and low voltage switch, convenient, no leakage; 8. with oil and oil filter technology, foreign body into the hydraulic system. Further improve the hydraulic system reliability and component life; 9. hydraulic hose hose. Use: widely used in commercial concrete demand for large, high grade and strict quality requirements, long conveying distance of high-rise buildings, municipal construction, electric power, energy, transportation and other civil and industrial buildings, especially the construction of the narrow space more show its true colour of a hero.
Q:What is the use of spare parts prices in Chinese market by foreign companies?
You might be gathering information for him. You have no data for one person, if there are several people? They can analyze a lot of things through big data. You can't find out, you're OK. Once you find out, your whole life is over.
Q:Definition of large mechanical equipment?
The hoisting machinery used in bridge construction can be divided into three categories: light and small lifting equipment, bridge type crane and boom type crane. Light and small lifting equipment, such as jacks, hoists, winches, etc.. Bridge type lifting machinery, such as beam cranes, Longmen cranes and so on. Boom type cranes, such as stationary slewing cranes, tower cranes, truck cranes, tires, crawler cranes, etc..
Q:What are the mechanical drawing software?
Personally, CAD is suitable for large machines or buildings, and CAXA is the real machine industry's universal software, and can also save drawings in various formats.
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?
Classification ah! Put small pieces of different sizes and functions into boxes and attach labels; larger items can be placed outside in a certain order (for example, function, length, value, etc.)
Q:Mechanical bearings, all types? Roughly
Spherical roller bearings have two raceways in the inner and outer ring raceways between spherical assembly, a drum shaped roller bearings. The center of curvature of the raceway of the outer race is consistent with the center of the bearing, so it has the same self-aligning function as the self-aligning ball bearing. When the axle and shell are bent, the axial load in two directions can be automatically adjusted. Radial load capacity, suitable for heavy load and impact load. Inner diameter is tapered bore bearings can be installed directly. Or the use of tight sets, the demolition cylinder installed on the cylindrical shaft. The cage uses a steel plate holder, a polyamide forming cage and a copper alloy car holder.
Q:What functions should be achieved in mechanical structure design?
The main features of the mechanical structure design are: (1) it is a set of thinking, drawing and calculation (sometimes necessary experiments) in one of the design process, is involved in machinery design, the most specific, the largest volume of work, in the whole process of mechanical design, an average of about 80% of the time for the structure design plays an important role in the success of mechanical design. (2) the multi solution of mechanical structure design, that is, the mechanical structure that satisfies the same design requirement, is not the only one. (3) the mechanical structure design stage is a very active design link, often needs to cross repeatedly. Therefore, in the design of mechanical structure, it is necessary to understand the basic requirements of the mechanical structure from the whole of the machine
Q:Construction machinery production need to deal with what documents?
Two, enterprise legal person business license (copy), with enterprise legal person business license duplicate copy, search three, all levels of safety production responsibility system and safety production rules and regulations directory and documents, operation procedures directory
Q:Where are the hanging baskets for the building?
It is forbidden to take a stool or put a ladder on a hanging basket to work higher; it is not allowed to work alone in a basket, and no electric machinery or equipment can be placed in the basket;
