Steel Material Hoffman Kiln YDS 30 0.04m/s Pushing Speed 5.5kw

Steel Material Hoffman Kiln YDS 30 0.04m/s Pushing Speed 5.5kw

Product Description

  The hydraulic stepper pusher is the key equipment for bricks and tiles plant.The car pusher pushes the kiln car into the tunnel kiln and make the kiln car move farward in the tunnel kiln.The hydraulic car pusher adopt only one hydraulic station which could drive the moving system and operate system separately,thus just one person is needed to complete all the operation.

   Wangda machinery factory specialize on the design and manufacturing heavy duty hydraulic cylinder used forthe tunnel kiln car pushers .

Design

     Not only we could manufacture all kinds of heavy duty hydraulic cylinder on hydraulic car pushers

according to the drawing from customers,but also we could make a design according to  customers’requirements . If you require our engineer to make a design , please advise us the

following specification :

1. Rated pressure

2. Working pressure

3. Test pressure

4. Working condition and environment ,for example ,temperature ,working frequency

5. Pulling force ,and return stroke force

6. Pulling and return speed

7. Assembly size

8. Seal ring requirements .For example , brand ,seal material etc .

9. Tube and piston rod raw material requirements

10. Piston rod surface treatment requirements, for example chromating film thickness ,

Surface hardness etc .

11. Painting and other spare parts requirements .

Technical Parameters

Manufacturing and inspection

1. Cylinder tube size and choice

  1.1 According to the cylinder pressure and inside diameter size ,different steel tube Would be choosed .

a. ID ≤300mm , cold rolled precision seamless tube would be choosed

b. 300mm≤ID ≤500mm , hot rolled seamless tube would be choosed

c. 500mm≤ID ≤1000mm, forged tube would be choosed

  1.2 Cylinder tube steel grade : SAE1020 , SAE1045 ,27SiMn , S355JR ,S355J2G3

St52-3 ,SUS304 ,SUS316L etc .

  1.3 Cylinder tube inside boring and honing , roughness R0.2-R0.3,

  1.4 Cylinder tube inside chromating : if necessary ,tube inside chromating could be applied

2. Piston rod is a very important part for hydraulic cylinder .

  2.1 Piston rod steel grade : SAE1045, 42CrMo4, SUS410 ,SUS420, SUS304, SUS316L

  2.2 Piston rod chromating and surface hardness .

Eternal company ensure that every piece piston rod would be surface hardened before chromating ,

surface hardness is HRC55~60 , Chromating film thickness is 0.03~0.04mm if there is no other specific

requirements .

3. Seal ring and O ring

   According to the customers’ requirements and working condition , eternal company would choose suitable

seal ring kit , seal ring brand include :Parker , Merkel , NOK , Guangzhou Rubber institute , Taiwan brand etc . Eternal company would supply suitable seal solution for their customer so that hydraulic cylinder has more lifetime , easy maintenance and simple repairing .

4. Tube and flange welding

  The welding on cylinder tube and flange would be Ultrasonic tested every time , the welding seam would be cleaned before machining .Eternal company ensure that every welding seam has no any leak during lifetime

5. Assembly and pressure test

   Before hydraulic cylinder is assemblied , every spare parts would be measured and cleaned .After hydraulic cylinder is assemblied , pressure test would be carried out one By one , eternal company ensure that testing pressure is higher 30%-50% than working pressure , and pressure holding time 30~60 minutes is necessary . Every piece hydraulic cylinder must be tested completely without any leak .

4.6 Painting and storage .

   After hydraulic cylinder pass through pressure test , painting is necessary .
