Introduction of the main characteristics of concrete mixing plant

Concrete is the main material of today’s construction, the use of this material for us to help the role is relatively large. In life we ​​often use concrete to the concrete mixing station when processing and mixing concrete. For this device, I believe we are in life there is a certain understanding, then the characteristics of this device have what?


The concrete mixing station is mainly divided into four parts: gravel feeding, powder feeding, water and admixture feeding, transmission mixing and storage. The whole body is made of steel structure. The high quality H-shaped steel is not only beautiful in appearance but also strengthened The concrete structure of the concrete mixing station strength, equipment, convenient installation, can be applied to a variety of complex terrain structure.
Good mixing performance, the device uses a spiral double horizontal shaft forced mixing host, not only the mixer is strong, for dry hard, plastic and a variety of concrete can achieve a good mix of mixing effect. And stir evenly, high efficiency.
The concrete mixing plant not only has excellent mixing host, but also has a variety of sophisticated accessories, such as screw conveyors, metering sensors, pneumatic components, etc., these components to ensure that the concrete mixing plant in the operation of a high degree of reliability, accurate measurement skills and Long service life. At the same time, the concrete mixing plant maintenance stations are equipped with station or check ladder, mixing station, and has enough space to control, stirring the host can be equipped with high-pressure automatic cleaning system, with a function of oil and over-temperature automatic alarm function, service.


Concrete mixing station is composed of mixing host, material weighing system, material conveying system, material storage system, control system composed of five major systems and other ancillary facilities of the building materials manufacturing equipment, the main principle of its work is cement cementing materials, Sand, lime, cinder and other raw materials for mixing, and finally made into concrete, mixing station, as the wall material into the construction and production. Since the concrete mixing plant has been put into use, it has played an important role in the construction and construction industry of our country. Of course, this is also determined by the superior characteristics of the concrete mixing plant itself.


Good environmental protection function, in the process of running the machine, powder handling are carried out in the full block system, the use of high efficiency dust collector / spray spray and other methods greatly reduce the dust on the environment pollution, while the concrete mixing station on the pneumatic system Exhaust and discharge equipment are used muffler device to effectively reduce the noise pollution.

Reason and Corresponding Solution of Gas Supply Fault in Concrete Mixing Station

Concrete mixing station gas source failure and solution:
(1) air compressor failure are: check valve damage, piston ring wear serious, damage to the inlet valve and air filter blockage.
To determine whether the reversing valve is damaged, only in the air compressor automatically shut down ten seconds later, turn off the power, hand wheel to move a large tape pulley, if more easily turn a week, then check the valve is not damaged ; In addition, the anti-valve has been damaged; In addition, can also be from the automatic pressure switch below the exhaust port to determine the situation, usually in the air compressor automatically shut down after about ten seconds to stop the exhaust, If the exhaust has been stopped until the air compressor starts again, it means that the check valve has been damaged and must be replaced.


When the pressure of the air compressor is slow and accompanied by the phenomenon of oil, indicating that the air compressor piston ring has been seriously worn, should be replaced.
When the intake valve is damaged or the air filter is clogged, the pressure on the air compressor will also rise slowly (but there is no oiling). Check, the palm of your hand can be placed on the air filter inlet, if there is hot air to the top, then the inlet valve has been damaged, to be replaced; if the suction is small, the air filter is generally dirty, The filter should be cleaned or replaced.


(2) failure of the valve are: the pressure is not high, or the pressure rise slowly. Pressure is not high, often due to pressure spring breakage or diaphragm caused by the rupture, must be renewed; pressure rise slowly, generally caused by the filter was blocked, should be removed cleaning.


(3) pipeline failure are: pipe joints leak, hose rupture, condensate accumulation and so on.
Pipe joints leak and hose rupture from the sound up to determine the location of the leak, should be promptly repaired or replaced; if the pipeline is condensed with condensate, it should be drained in time, is characterized in the winter of winter condensate easy to knot Ice and block the air.
(4) Compression air handling components (triple body) failure: oil and water separator failure, pressure regulator and oil mist failure.
Oil and water separator failure is divided into, filter blockage, damage, the movement of moving parts of the valve is not flexible and so on. Work to always clean the filter, remove the oil and impurities in the sewage.
