Concrete cost reduction

The bottom line cost reduction resulting in mass concrete has been a breakthrough on the one hand is the environmental pressure and excess capacity , increased competition in the industry status quo , are forcing companies must upgrade the concrete , only transformation and upgrading, it may be in the rising market concentration Concrete batching plant market on a cost advantage to seize market opportunities , seize advantage to differentiate high-end market segments , in the new round of the jungle , out of the integration process , and achieved status of the industry , to achieve large-scale development . Concrete strength and durability targets main material is sand and concrete mix plant, we all know, the aggregate level with the "minimum gap " principle, can be achieved with less amount of cement and sand , especially in the high-speed rail applications such as high-performance concrete to reduce the amount of cement , but will increase the durability of the concrete life of a hundred years to really standard .

Press the gas supply fails

Air compressor failures are: non-return valve is damaged, badly worn piston rings , inlet valve is damaged and air filter blockage.
To determine whether the non-return valve damage , just ten seconds after the compressor automatically shut down , turn off the power , the hand plate moving large belt wheel , if can more easily turn a week , Concrete mixing plants valve is not damaged ; the contrary, non-return valve is damaged; Further, the pressure switch from automatic exhaust vent below the case to be judged , in general , after the air compressor should be shut down automatically after about ten seconds to stop the exhaust , If you have been in the exhaust until the compressor starts again when to stop , precast concrete plant valve is damaged, must be replaced .
When the pressure of the air compressor oil rises slowly and accompanied by string phenomenon that has been severely worn piston ring compressor , should be replaced.

Municipal Quality Supervision Bureau

Municipal Environmental Protection Bureau , Municipal Quality Supervision Bureau to strengthen its duties detergency gasoline and diesel vehicles , vehicle NOx reductant and production of oil quality supervision.
Concrete mixing plants Protection Bureau annual inspection and sampling tests led oil storage facilities , gas stations and oil and gas recovery tankers less than 30,000 times ; promote the implementation of more than 5,000 tons oil and gas recovery line monitoring renovation project ; 2013-2014 to carry out oil and gas filling stations online monitoring of research and pilot recovered in 2015 to promote the implementation . Main measures and time nodes: 2013 ban on new research to develop the city , precast concrete plant industrial project directory , 2014 promulgated. If necessary, every 2-3 years to be updated. In principle prohibiting the construction of iron and steel, cement , coke, non-ferrous metal smelting, aluminum , glass , calcium carbide , ferroalloy, bitumen membrane high energy consumption, high pollution projects , no general construction labor-intensive manufacturing projects .

Metal smelting equipment growth conditions

Machinery and equipment performance has been divided , metal smelting equipment situation is significantly better than the growth in packaging and feed equipment . According to Bureau of Statistics data show that in July of metal smelting equipment production was 77,000 tons , an increase of 31.4% , the growth rate down 0.4 percentage points from the previous month , but the overall level is still high . July packaging equipment production was 8965 units, an increase of 8.5% , the chain fell 5.9% , down slightly from last month to expand. July feed production equipment 31,000 units , Concrete batching plant , down a row in March to expand. Construction machinery industry this year has been a weak recovery trend , in July as the off-season , sales are also not much improvement. According to the latest statistics Industry Association , July 28 major manufacturers of excavators excavators 6351 units were sold , an increase of 8 % growth rate in June rose 7.4 percentage points from batch mixing plant cumulative sales of 75,305 units excavator industry , down 10.88 percent , a decline trend was improving . Ring than in July fell 24 percent excavators , meet seasonal characteristics , but has narrowed down over the previous March , the emergence of this improvement is mainly driven by sales of foreign brands in the last month due.

Maintenance and quality assurance of

Machinery repair and maintenance . Including the warranty period free of maintenance and quality assurance are outside.Compensation for service. The current industry trend is from the engineering machinery and equipment maintenance steering periodic maintenance ,Stabilized Soil Mixing Plant and maintenance of both, maximizing extend equipment life , adding value to our customers through service. 2 rental service leasing market is facing great opportunities : First, mechanical equipment required for the works Prepare varieties increased , shorter duration , lease equipment costs than enterprises occupy low ; Second , leasing can avoid Free introduction and stationary concrete batching plant equipment due cycles technical risks ; Third, hire purchasing the enterprise week Turn more flexible, while avoiding the effects of inflation , reducing investment risk.

Failure of oil-water separator

Regulator fault with the "valve failure" identical.
Lubricator fault phenomenon: no drop of oil deposited on the bottom of the oil cup water, oil cup seal failures. Concrete batching plant does not drip, check the inlet gas flow rate is below the fog flow, leaks, clogged fuel adjustment needle, etc.; if the oil cup bottom sediment moisture, should be immediately removed; when seal is damaged, should be replaced.Leaking pipe joints and hose rupture up to judge the sound leak from the site, should be promptly repaired or replaced; if there is accumulating condensate pipeline, it shall promptly drained, is characterized by condensed water in batch mixing plant winter, easy to knot Ice and clogging gas.
Compressed air processing components (triplets) faults are: oil and water separator failure, regulator and lubricator failure.
Failure of oil-water separator is divided into, filter clogging, breakage, drain valve moving parts moving parts is not flexible and so on. Work should always clean the filter, remove sewage and impurities inside the oil.

advantages of concrete mixing station

1 high reliability of concrete mixing standing after ten years of development , the development process is the introduction - digestion - some domestic - all homemade - improvements to improve . Stationary conacrete plant concrete company for production of 10,000 cubic meters of concrete is normal , and its key components such as hosts, screw machine , the main control and pneumatic components performance has been fairly stable, such as the mixing blades using a unique high-chromium alloy wear-resistant high manganese material , shaft bearings and seals form a unique multi-sealed or hermetic , greatly enhancing the host's reliability. Often impacted on , precast concrete plant, such as in discharge hopper , wear-resistant steel transition bucket , etc. to strengthen in the interior portion ; ring belt vulcanizing adhesive joints , riveting life than ordinary steel increased by 3 times, which is to ensure that reliable high prerequisite.
