Processing method of plugging concrete placing boom

Concrete placing boom in the course sometimes occurs concrete fabric conveyor pipe blockage we call this concrete fabric plugging.
Concrete placing boom occurred plugging phenomenon is mainly caused by the following reasons: 1 concrete placing boom itself caused by design flaws, such as fabric machine elbow angle design is unreasonable, and concrete placing boom flanged joints welded pipe inner wall irregular and so on. 2 concrete pump pressure is not enough, or does not comply with the cloth conveying concrete grade caliber machine design. Resulting in a large pipe cleaning not been retained in the cloth solidified concrete conveyor pipeline after 3 concrete placing boom last construction work is completed. Truemax has not been washed concrete placing boom line 4 first job or starting job.
In summary fabric machine because no matter what causes concrete fabric plugging phenomenon, the first task is to clear the fabric machine too long pipeline to prevent solidification of concrete caused the entire conveyor system forming fabric machine scrapped. Fabric machine line can be as slight blockage red rinse water pressure to clear the pipes. Such as fabrics machine piping system congested close now to be found clogging percussion test site, and then open the blockage occurs in the fabric tube card disassembled machine parts as needed, and then carry on tapping outer pipe to clear, note spreader pipe no steel or iron strips applied to clear in order to avoid more pressure the more real. Concrete placing boom after pipeline dredge to find out reasons for the blockage to develop solutions for the reason, so as not to produce again cloth plugging construction.

Operating system and the performance of concrete pump truck

Control concrete pump electrical control system there are five main mechanical, hydraulic, electromechanical electrical control type, the programmable controller type, logic-controlled. In addition to the concrete truck pump control system to complete the installation of electrical control tasks, is also equipped with a manual control to manipulate the system, it is also part of the system of control. 

If mechanical manipulation, generally bar system controls and flexible shaft steering mechanism in two ways. If you compare the two is not difficult to find, flexible shaft control mechanism have more advantages, such as layout flexibility, high transmission efficiency, transition joints and small air travel less convenient travel adjustment, etc., so theconcrete pump control system The main shaft is to select the operating mechanism. According to actual needs, in truck’s operating system should be able to achieve variable speed operation, while enabling the joystick to stop at any position locking mechanism is a key means to achieve stepless operated, generally you can use the disc springs or spring board. For ease of operation, joystick are designed to be installed at a convenient location, such as Putzmeister BSF36.09Z type pump, which controls the engine speed joystick mounted on the side of the ladder, the operation is very convenient. Concrete pump control system is mainly used to control the main pump flow and engine speed, thereby changing the concrete pump discharge amount. Such as the use of hydraulic control, it can get power directly from the hydraulic drive pump pumping systems, and to achieve through manual hydraulic control valve. There is a close relationship with the properties of concrete, while paying attention to detail procedures in the course of operation, the timely detection and timely troubleshooting to improve pump efficiency. There are two methods to clean water pipes and gas wash. Whether it is water or air wash, should the valve housing and hopper clean. When washing, the water soaked tied cylindrical cement bags and cleaning ball has been put into clean cone tube, connected to the cone, pipe, close the discharge door, hopper filled with water again (to be kept Water constantly). Pumping water until cleaning ball out from the tip of the delivery tube so far. Gas wash or compressed air purging, is the first water-soaked cleaning ball into the air purge fitting, connect with the adjustable tube connecting the first root straight, and at the end of the pipe connected to the safety cover, safety cover opening to down. Control air pressure does not exceed 0.8MPa, slowly open the valve, when the concrete can flow smoothly before opening a large valve.

HOW TO REDUCE THE WEAR OF CONCRETE MIXERS?

concrete mixer

When using the concrete mixer, how can we make the operation more concrete mixers reduce wear, thus extending the life of concrete mixers. In fact, to ensure that concrete mixers reduce wear and tear, it should be necessary to pay special attention in the run-in period.
Run-in period is all kinds of concrete mixers must go through a phased work in run-in period, how to ensure the normal operation, the failure rate of decline in the concrete mixer, extended core purpose of safety of life, through the period of rest, we must understand. Then, in the run-in period when the concrete mixer in use need to pay attention to what things?
Troubleshooting Running concrete mixer: poor lubrication, due to the new assembly parts combined with the gap between them is small, and due to assembly and other reasons, it is difficult to ensure the uniformity of the gap, the lubricating oil is not easy to form a uniform film on the friction surface to prevent wear. To reduce the lubricating effect, so in the early abnormal wear of parts. It caused serious friction with the surface scratches or wear and failure.
Since the new machine parts processing factors concrete mixer, assembly and regulation, such as friction surface contact area is small, unequal status surface pressure, wear faster. At this time, if overloaded, it could cause parts damage, early failure. So, when the concrete mixer used in run-in period, and must not use it for work overload, so that the life of the concrete mixer will be undermined

Chinese concrete machinery: implementation of national standards of confusion

The first half of this year, visited the concrete machinery industry more than ten enterprises, almost all business leaders believe that only the upgrading of products as soon as possible, innovation, continue to improve the core competitiveness of enterprises, in order to occupy a place in the big market at home and abroad, continue to maintain this year good momentum of development, and after the party's eighteen new industrialization, intelligent, urbanization, agricultural modernization construction machinery pulling and lifting with confidence and expectations. 

However, when referring to the Chinese construction machinery in the future how to better development, whether it is business leaders or scientists, marketers have expressed varying degrees of doubt and misgivings. Especially for the concrete machinery industry do not know when to get out of the ecological environment and the plight of developing the disorder vicious competition. Some marketers even expressed great dissatisfaction and anger. Almost went, regardless of size enterprises, have said that we should cherish the good pay in our era of opportunity and responsibility, especially in some large companies. Since the reform and opening up in recent years, the rapid development of the country universally belong mesh, pulling and promote the rapid development of construction machinery. Most entrepreneurs can lead to snobbish, exploration and development of the Chinese market and non-market pull Europe, in time to meet market demand. Also greatly enhance China's construction machinery industry integrated innovation ability, basic components of global sourcing makes performance and quality of construction machinery reached world advanced level. 

Especially China business philosophy and strategy unique, all-weather service, life-long service and low-cost advantages, etc., to attract Chinese and foreign customers in these markets, so China's construction machinery with a considerable competitive edge. It is because of these advantages enable us to beat when the international economic downturn in some of the world's extreme brand of big business internationally. Just as weather, geography is extremely advantageous for us, if we unite, we engaged in the planning, development of basic components, such as power, transmission, hydraulic, controllers, sensors and other modern 3D printing technology design and manufacturing technology, we will be able to In the third technological revolution the world's continued occupation of the highest point. 

However, contrary to expectations, concrete machinery is still a promising industry, the industry should be more enterprises to participate in leadership and small enterprises should have a peace of mind, play to their strengths in the same environment, learn from each other, do not with industry leaders itself to me is great, what is the title of king of anything. History and reality have proven that big is not necessarily strong, not necessarily big and strong, fight the boss, often hidden behind the first fight with extreme irresponsibility, departing from the principle of national interests as the most important. The real model should be based on their own corporate culture, the spirit of innovation, the concept of humanity, for the state and the industry to develop products suited to market needs, in a highly competitive market in a harmonious state-owned share dividend desire to develop their own development strategies and policies, can not eat stimulants magic to fight the order, and highly praised by users. In the development of the self, for the industry to provide the infrastructure components to provide bedding for the industry and the national industrial development. Such entrepreneurs and their business will naturally get industry recognition and respect, naturally become a benchmark role model, by maintaining self-sealing crown soon.
