Belgium hydraulic cylinder,reset cylinder manufacturer,reset cylinder
(Belgium reset cylinder,produced by Hengyu Group）
reset cylinder are widely used in Belgium，because of no transmission clearance，powerful torque，clever hydraulic energy conversion.So our company has designed reset cylinder for customers from Belgium.
reset cylinder is the most important part of construction machinery, the traditional processing method is: broaching reset cylinder block - fine boring reset cylinder block - grinding reset cylinder block. The rolling method is: broaching reset cylinder block - fine boring reset cylinder block - rolling reset cylinder block, the process is 3 parts, but the time is compared: grinding 1 meter of the reset cylinder block is about 1-2 days, rolling 1 meter of the reset cylinder block is about 10-30 minutes. Input comparison: grinding machine or quilting machine (tens of thousands - millions), rolling knife (ten thousand - tens of thousands). After rolling, the surface roughness of the hole decreases from RA3.2-6.3 μm before rolling to Ra0.4 ~ 0.8μm, the surface hardness of the hole increases by about 30%, and the fatigue strength of the inner surface of the reset cylinder increases by 25%. If the reset cylinder life is only considered, it is increased by 2 to 3 times, and the boring and rolling process is 3 times more efficient than the grinding process In particular, if you want to make high-quality reset cylinders, you must take the rolling production process. After the reset cylinder is rolled, there is no sharp tiny edge on the surface, and long-term motion friction will not damage the seal ring or seal, which is particularly important in the hydraulic industry.
reset cylinders in series, parallel and series parallel. Series: In the reset cylinder, the oil inlet of the subsequent reversing valve is the supply of the previous oil return, and there is no separate oil return circuit connected with the oil return in each valve. Series: In the reset cylinder, the oil inlet of the subsequent reversing valve is the supply of the previous oil return, and there is no separate oil return circuit connected with the oil return in each valve. Parallel: the pressure oil in the reset cylinder is connected with the inlet oil of each reversing valve, and the return oil is collected by the return oil circuit. Series parallel: For this one, compared with the simple series and parallel, it is slightly more complicated, but it is not impossible to understand. The series refers to the oil in the reset cylinder, which is in series form, but can not form a series circuit, and the parallel refers to the oil return circuit of each valve, which is in parallel.
We can not just consider the price and ignore the quality when we purchase the reset cylinders. Now some manufacturers produce unqualified products in order to reduce costs, the piston rod is not adjusted, the rod coating is not enough, the reset cylinder finish can not reach, the guide sleeve should use copper, but instead of ductile iron, although the cost is reduced, the quality of the reset cylinder is not required.
If the seal of the reset cylinder is softened and sticky, it may be that the seal is incompatible with the hydraulic oil or the nearby lubricating oil, replace the appropriate seal; If the seal becomes hard and loses elasticity, most of it is because the ambient temperature is too high (more than 80 ° C), make appropriate temperature insulation protection or replace the high temperature seal.
How big is the 100t cylinder pump and how big is the motor?
Load is calculated at 15 tons, stroke is calculated at 100 (both take the maximum) 15 tons = 15,000 kg, 15,000/210 bar (21 mpa) =71.42 square centimeters (cylinder area) 71.42/3,14 In the root *2=90,5 the inner diameter of the cylinder can be taken 100 mm. Travel 100 cm, that is, one meter, assuming 10, seconds a back and forth, then it is six times a minute, six meters per minute, then the required flow is,71,42*600 cm (6 meters) =42840 mm =42.84 liters/minute 42.84*21/60=14.9 kilowatts can choose 1450 RPM 4-stage motor 15KW.
What is the material of the hydraulic cylinder slider?
Three parts of the hydraulic cylinder are essential, which are: cylinder - cylinder head assembly, piston - piston rod assembly, and sealing device. When you say slider, you mean piston. - Piston rod. Piston materials commonly used gray cast iron, wear-resistant cast iron, aluminum alloy (assembled), etc., can also be used 35 and 45 steel (integral). The piston rod is generally made of 35 and 45 steel. When the impact vibration is large, alloy steel such as 55 steel or 40Cr is used.
