Cylinder Failure-One of the Common Faults of Concrete Mixing Station

2024-08-06

Due to improper assembly and long-term use of the cylinder, the pneumatic actuator (cylinder) is prone to internal and external leakage, insufficient output force and unstable action, poor cushioning effect, piston rod and cylinder head damage and other failures. (1) Internal and external leakage of the cylinder is generally caused by eccentric installation of the piston rod, insufficient supply of lubricating oil, abrasion or damage of the sealing ring and sealing ring, impurities in the cylinder and scars on the piston rod. Therefore, when the cylinder leaks internally and externally, the center of the piston rod should be readjusted to ensure the coaxiality of the piston rod and the cylinder. Always check whether the oil mist sprayer works reliably to ensure good lubrication of the actuator; When the sealing ring and sealing ring are worn or damaged, they must be replaced in time; If there are impurities in the cylinder, they should be removed in time; When there are scars on the piston rod, replace it with a new one. (2) The output force of the cylinder is insufficient and...

Air Source Fault-One of the Common Faults of Concrete Mixing Station

2024-08-06

(1) The faults of air compressor include: damage of check valve, serious wear of piston ring, damage of air inlet valve and blockage of air filter, etc. If you want to judge whether the check valve is damaged, just turn off the power supply after the air compressor stops automatically for more than ten seconds, and turn the big belt wheel by hand. If you can rotate it easily for one week, it shows that the check valve is not damaged. On the contrary, the check valve has been damaged; In addition, it can also be judged from the exhaust situation of the exhaust port under the automatic pressure switch. Generally, after the air compressor stops automatically, it should stop exhausting after about ten seconds. If it stops exhausting until the air compressor starts again, it means that the check valve has been damaged and needs to be replaced. When the pressure of the air compressor rises slowly and is accompanied by oil string phenomenon, it shows that the piston ring of the air compressor has been seriously worn and...

How to Transport Concrete with Transport Tankers After Production

2024-08-06

1. The speed of service road: 24 km/ h, taking the round-trip transportation distance of 24 km as an example. 2. Loading time of concrete mixer truck: 1/6 hour/car for HZS120 and 7/30 hour for HZS90. 3. Unloading time of concrete mixer truck: 5 minutes. 4. Every time one truck of concrete is delivered, it takes 1.25 hours for HZS120 and 1.32 hours for HZS90. 5. The number of vehicles to be transported within 6 hours: HZS120 6×1/1.25≈5 (vehicles) and HZS90 6×1/1.32≈4 (vehicles). 6. 320 m3 of beam pouring concrete is completed within 6 hours, and the number of vehicles to be transported is 320×1/6.5≈50 (vehicles). 7. The allocation of concrete mixing truck should be considered. Due to the service road transportation, there should be a certain empty tank rate. HZS120 mixer station, with a host capacity of 2m3, should be equipped with a 9 m3 concrete mixer truck for loading four plates of materials. The transportation distance is about 12KM, and 320 m3 of concrete is poured on the beam within 6 hours, which is suitable for 10~11 concrete...

What Should be Paid Attention to When Buying Concrete Mixing Station

2024-08-06

1. Performance label of construction concrete From this, we can choose what kind of mixing machine to use. For example, in water conservancy projects, the forced mixing host must be selected. In addition, batching stations and storage bins should be selected according to the types of concrete materials that can be mixed. 2. Task quantity and construction period of concrete construction Use these two parameters to select the mixing station with large specifications. Let the total task of concrete be m; The number of concrete pouring days is T; The working hours per day are h; If the utilization coefficient is K, the specification of the mixing station should be X=M/(T*H*K), where K is 0.7-0.9. In the selection, the transportation condition of finished concrete should also be considered. Such as: direct pumping or vehicle transportation. The volume of conveying vehicles is also an important basis for determining the type of mixing station. 3. Construction environment and construction object When choosing to buy concrete mixing station, the influence of construction object and construction environment should be fully considered, so as to...

Components of a Standardized Concrete Batching Plant

2024-08-02

A standardized concrete batching plant is essential for producing high-quality concrete efficiently. This article explores the key components that make up a standardized concrete batching plant, ensuring you have a comprehensive understanding of each part. 1. Aggregate Batching Machine The aggregate batching machine is a crucial component, responsible for storing and measuring different types of aggregates, including sand, gravel, and crushed stone.

Difference of Feeding Mode of Diesel Concrete Mixers

2024-08-01

Introduction JZC series diesel concrete mixer is a self-falling concrete mixer with double-cone mixing drum for forward mixing and reverse discharging. Each tank can mix 350 liters, 500 liters, 750 liters of concrete (referring to the volume of compacted concrete), and can produce 6-22 cubic meters per hour. The diesel concrete mixers are suitable for general construction sites, roads, bridges and small and medium-sized concrete component factories. Difference The difference between the diesel concrete mixers is the control method of the hopper lift. The 350 liters concrete mixers has two types: wire rope and hydraulic, while the 500 liters concrete mixers and above models only have hydraulic. The JZC500-DH diesel drum concrete mixers can be easily disassembled and transported. It is the best mixer for various areas without power supply and construction sites where it is inconvenient to introduce power lines.
