Concrete mixer and concrete pump

1. Concrete Mixer and Concrete Pump Abstract: Twin shaft concrete mixer is the main concrete mixer used today. 2 yard concrete mixer has theoretical productivity of 90 cubic meters per hour. The main types of concrete pumps are small concrete mixer with pump, line pump trailer, concrete pump truck. 2 Yard Twin Shaft Concrete Mixer At present, the twin shaft concrete mixers are 1,3,4,2 yard concrete mixer. This series of concrete mixers have very high mixing efficiency and good mixing performance. They can mix different concretes and are suitable for all kinds of large, medium and small prefabricated component factories and industrial and civil buildings such as roads, bridges, water conservancy, ports, and wharves. In addition to being used alone, PLD800\PLD1200\PLD1600\PLD2400 and other concrete batching units to form a simple concrete batching station or used as the mixing host of the concrete batching plants. it can also be combined with 2 yard concrete mixer has a feeding capacity of 2400L, a discharge capacity of 1500L, and a theoretical productivity of 90 cubic meters per hour. In addition to stand-alone operation, it can also form a simple concrete mixing station with the PLD1600 batching machine, and can also be

2. used as a mixing host of HZS75 or HZS90 concrete plant. It has the advantages of high degree of automation, good mixing quality, high efficiency, low energy consumption, low noise, convenient operation, fast unloading speed, long service life of lining plates and blades, and convenient maintenance. 2 yard concrete mixer, also called JS1500 twin-shaft mixer, can be divided into two types: cycloid reducer and planetary reducer. The height of the outrigger part is designed as: 2.7 meters of outrigger height and 3.8 meters of discharge height. How to choose a right twin shaft concrete mixer? Its quality mainly depends on its shaft and blades. From a long-term perspective, it is recommended that customers try to choose blades that are connected by screws instead of cast steel, as the blades are easy to break. Haomei Machinery is a well known twin shaft concrete mixer manufacturer. Its shell is welded and formed in the factory, and assembled with other components, which is the support of the twin-shaft mixer. The shell is tightly sealed, and there will be no phenomenon of flying ash and ash leakage. Small Concrete Mixer with Pump The small concrete mixer with pump is to combine the traditional mixer and concrete pump as a whole and is welded on a frame with axles, which is pulled by a small truck or small loader to transfer between several construction sites or between multiple construction points, thus maximizing the reduction of interval time. Compared with truck mounted concrete pump and boom pump truck, concrete mixer pump is the cheapest. They are divided into electric concrete pump and diesel concrete pump. The difference lies in whether the power source of the hydraulic system is provided by the motor or by the diesel engine.

3. When buying a concrete mixing pump trailer, the configuration of the product cannot be ignored. It is usually necessary to observe the frame thickness, workmanship and materials of other key parts. When selecting parts, the material of the hydraulic hose and the lubricating copper pipe is as important as the "main oil pump", the heart of the concrete pump. The key parts of Haomei concrete mixer with pump adopts high wear-resistant parts imported from the well-known brands, which can ensure the progress of uninterrupted construction 24 hours a day. The service life is increased by 30% to more than 10 years, and the service life of the concrete conveying cylinder is more than 150,000 cubic meters. Pumped concrete is different from traditional concrete construction methods. The requirements for concrete not only meet the strength and durability specified in the design, but also meet the requirements of pipeline transportation for concrete mixtures, that is, concrete mixtures should have good pumpability. In June 16, 3 sets of small concrete mixer pump were sent to Malaysia. In the early stage, Malaysian customers conducted a live video inspection of our factory and spoke highly of the company's technical strength, production capacity, product quality, product certificates, shipping capabilities, after-sales service, etc. This was owed to our deep study of the the Malaysian market. According to the specific situation in Malaysia, related technical improvements have been made to the heat dissipation performance, fuel consumption, controllability and comfort of the mixing pump. Self Loading Mixer Truck In recent years, the application of self loading mixer trucks in the engineering projects is more and more popular. Whether it is in the city, in the township, or in the mountains, it can self load, mix, transport and discharge 270 degrees. What are its specific advantages? High efficiency

4. Take the HM4.0 self loading concrete mixer as an example. It take 12 minutes on average to finish a batch. If the working hours is 10 hours, the daily concrete output can reach 500 tons, which is several times higher than that of simply using a mixer. Cost-saving The cost that can be saved by the self-loading mixer is the material cost and labor cost. As we all know, the price of commercial concrete is always high. Calculated by using 80 cubic meters of concrete per day, the commercial cost is about 24,000 while the raw material price of concrete is not more than 100 yuan. In the past, 7 or 8 workers were required to make concrete together. Due to the high automation, the self loading concrete mixer truck only requires 2 workers. One person is responsible for the operation, and the other one is to assist him. Based on the daily salary of 150 yuan, the labor cost can be saved at least 600 yuan per day, and it can reach 18,000 yuan a month. Strong adaptability Going up the mountain is too difficult for a large tanker truck, but it is quite easy for a self concrete mixer truck. Take HM2.0 self concrete mixer truck for example. Scientific design, articulated body and four wheel drive makes it climb on the slop of 30 degrees easily. It also has excellent working performance on the plateau because we can customize the "plateau machine" that suits the local environment for users. High configuration There are rich models for the customers to choose from. It has the highly intelligent digital display touch screen, sensitive frame and small turning radius. If you need, the self loading mixer can realize dual driving operation. Other advantages 1. Building a 10km*3km*20cm road can earn back the cost. 2. Compared with the original construction operation, it can reduce 4 workers. 3. It is equivalent to a mobile mixing station. The self concrete mixer truck is widely used in the road hardening, house building, squares, workshops, tunnels,etc. It reduces labor and costs by 30% compared with traditional operating machinery, and is also the first choice for rental in the construction rental market. 36 Meter Z Boom Concrete Pump Concrete pump trucks are the modern concrete construction equipment integrating driving and pumping functions. It can ensure the construction quality of engineering construction, improve construction efficiency, shorten construction period and reduce labor intensity. It is widely used in transportation, energy, water and electricity, nuclear power, construction, national defense engineering and other fields.

5. Different pump trucks will be designed according to the requirements of chassis length, width and height, mixer efficiency requirements, boom length requirements, etc. For example, under the condition that other configurations of the 33-meter pump truck remain unchanged, optimizing the boom design and adjusting the overall layout can get a 36 meter concrete pump. The higher the boom height, the larger the pouring height and the distribution radius, and the stronger the construction adaptability. The high boom should be used as much as possible in the construction. The boom with a length of 28-33m has a large market share, accounting for about 75%. How does the Z boom concrete pump work? After the concrete mixer truck unload the commercial concrete to the hopper of the pump truck, it is pressed to the conveying pipe by the pumping system and discharged through the end hose. The unfolding and retracting of each boom is completed by each boom cylinder. Among them, the elevation angle of the 1# boom can swing within -2°~90°, the 2# boom and the 3# boom can swing 180°, and the four-section boom is unfolded in turn, and the action of the 4# boom can swing about 255°. The hose at the end should be as close as possible to the pouring part when working, and the boom can rotate 365° around the fixed turret by driving the large rotary bearing through the rotary motor and the reducer. At present, Haomei Z boom concrete truck are equipped with wireless remote control technology, and some large concrete pump trucks use industrial TV monitoring. In the future, mechatronics will be the main development direction of concrete pump trucks.

6. Truck Mounted Concrete Line Pump In recent years, the upgrading of concrete pumps has developed rapidly. From line pump truck, truck-mounted pumps to boom pumps, the functions have been gradually improved. Due to the limitation of the height of the boom and the safety of the outriggers, the boom pump is very restricted in some narrow construction areas. The trailer pump has a wider application range. How to operate it daily? 1. Inspection before work Routine inspections include checking the hydraulic oil level, whether there is water in the water tank, the wear of wearing parts, the amount of lubricating oil, and whether there is any blocked pipe. If it is a motor pump, also check whether the external voltage is normal, whether the phase is missing, and whether the phase sequence of the wiring is correct. What is easily overlooked is the inspection of the amount of lubricating oil, which can lead to abnormal wear of the big and small ends and the mixing parts. . At the same time, the external pump pipeline should also be checked once to prevent the pump pipe from being worn and leaking slurry. 2. Matters needing attention at work Before pumping concrete, the truck mounted concrete line pump also needs to pump a certain amount of mortar to lubricate the pump pipes. At the same time, according to the increase in the length of the connected pump pipe, the amount of mortar provided also needs to be increased accordingly to prevent the end of the pump pipe from being without lubricating. Before the mortar has been pumped, the concrete should be put into the hopper to prevent the concrete cylinder from being emptied, which may lead to the occurrence of pipe blockage. At the same time, during the pumping process, the time for waiting for the concrete should not be too long. In summer construction, the longest interval cannot exceed 1 hour. The concrete pump trailer should be placed in a location that can block the rain, so that when it rains, the rain water won’t enter the hopper and cause the concrete to segregate. 3. How to deal with the blocked pipe Pipe blocking is one of the most common problems in daily working. First of all, after blocking the pipe, you should quickly find the location of the blocked pipe, clear the pipeline, and do not rush to work immediately after completing the above work. The reason for the blocked pipe should be found out. If the reason is not found, it is very likely that the pipe will be blocked again, and the newly unclogged pipe will be blocked again. Concrete segregation, too large particle size of concrete aggregate, leakage of slurry from pump pipe, insufficient pumping pressure due to equipment failure, poor sealing of piston, poor sealing of cutting ring of glasses plate, etc., may all lead to the occurrence of pipe blockage. Every inspection and troubleshooting is very important. Don't ignore some problems that you think are not problems. These may become hidden dangers of equipment failure in the future.
