In 2012, Dongfeng Cummins sold poorly, but it has gradually begun to pick up. Considering that the heavy-duty truck industry is expected to pick up in 2013, Dongfeng Cummins' performance will improve significantly.

Dongfeng Cummins Engine is mainly used for medium- and heavy-duty trucks and construction machinery. Downstream of Dongfeng Cummins Engine has a high correlation with fixed asset investment. Since the fourth quarter of 2012, domestic infrastructure investment has been increasing, real estate and logistics markets are picking up, and heavy truck industry data has been starting from September 2012. Monthly sales volume of the chain continued to improve, with a year-on-year growth of -11.2% in December, and the rate of decline continued to narrow. Coupled with the expectation of the National IV switching, the heavy truck market is expected to pick up in 2013. In December 2012, the sales volume of Dongfeng Cummins Engine also recovered to the level of the same period in 2011, and the rate of decline slowed down.

Pneumatic Cylinder Kits

Cylinder assembly accessories refer to all cylinder assembly parts except the piston rod, cylinder tube and tie rods (some cylinders do not have tie rods).

Cylinder assembly accessories include one front cover and one rear cover, one piston, two Y-type piston seals, one hard-wearing ring, one set of magnetic rings (some cylinders do not have magnetic rings), two cylinder seal O-rings, one piston rod sealing ring, one dustproof, two buffer caps, two buffer screws (with O-ring), one piston rod end thread, one piston fixing bolt, 8 fixing bolts, dustproof air inlet and outlet two caps, one piston rod end thread protection cover.Air Cylinder Tube.

Because the different application needs different strokes of air cylinders, for dealers and distributors, storing a large number of cylinders with fixed strokes will occupy a large amount of inventory funds.Pneumatic Cylinder Tube.

However, storing the Pneumatic Cylinder assembly parts can solve this problem very well. When requires different strokes and then temporarily assembling the cylinder accordingly.Air Cylinder Barrel.

Categories

Common cylinder assembly parts include DNC square cylinder series, ISO standard Metalwork series, SI Mickey Mouse type ISO 15552 cylinder series, SC and SU AirTac standard cylinder series, SDA compact cylinder series, and DSN, MA, MAL mini air cylinder series, etc. .


Matters needing attention when assembling the cylinder

For non-professional cylinder manufacturers, we do not recommend self-assembly to avoid problems caused by incorrectly assembling cylinders.

The following points need to be paid attention to when assembling an air cylinder by yourself:

â—† The inner edge of a pneumatic cylinder needs to be chamfered to facilitate the entry of the piston and sealing ring into the cylinder tube.

â—† Before assembling the piston and cylinder, lubricating grease must be applied to the inner wall of the cylinder to reduce the friction between the sealing ring and the inner wall of the air cylinder.Pneumatic Cylinder Barrel.

â—† The edge of the piston rod end also needs to be chamfered to reduce damage to dust and buffer seals.Pneumatic Cylinder.

â—† Because the end of the piston rod has external threads, special attention should be paid when assembling the piston rod and the front end cover. It is necessary to use the end of the piston rod without threads to pass through the gasket. Otherwise, the inner wall of the gasket is easily cut by the threads and resulting in an air leakage.

â—† For the installation of the tie rod cylinder, it is also necessary to pay attention to the position of the tie rod thread, so that there is enough thread space in the fixing bolts of the front and rear end covers to install the cylinder accessories such as CA, CB mounting brackets, FA/FB flange brackets.Cylinder Tube.
