Annually more than 8000 tons Precision casting and forging parts are exported to markets in Europe,America and Japan. OEM casting and forging service available according to customer’s requirement.
②How to guarantee the quality of the products？
- Q: How about the sealing ring for the piston rod seal?
- The sealing structure and sealing ring of piston rod is the key component in the reciprocating actuating mechanism. It is not only related to leakage problems, but also will affect the performance of the entire machine equipment and life. The piston rod in the reciprocating actuator, mainly to bear a certain axial force, and at a certain speed reciprocating movement to external work. With the development of science and technology and industry, the requirement of reciprocating motion is higher and higher. Especially in the case of high pressure and high speed movement, the problem of sealing structure and sealing ring of piston rod is particularly important.
- Q: What are the seals that are resistant to 500 degrees of high temperature?Airtight chamber gas temperature up to 500 degrees, what are the appropriate seals available? Thank you
- First of all, are you moving or sealed? Metals, semi metals, or high temperature nonmetallic materials can be used.
- Q: What is mechanical seal?Single mechanical seal? Double mechanical seal? What's the shaft seal?
- 2. mechanical seal is a kind of rotating machinery shaft seal device. Such as centrifugal pumps, centrifuges, reactors and compressors and other equipment. Due to the drive shaft through the inside and outside of the equipment, so there is a gap between the shaft and the peripheral equipment, equipment in the media leak out through the gap, if the device internal pressure below atmospheric pressure, air leakage to the equipment, so there must be a package of the shaft to prevent leakage. There are many kinds of shaft seals, because mechanical seals have the advantages of less leakage and long service life
- Q: Design of sealing ring, groove and bottom fillet of sealing ring
- The O ring seal is a typical extrusion seal. The compression ratio and stretch of the section diameter of O ring are the main contents of sealing design, which are important for sealing performance and service life. The O ring is usually installed in the sealing groove to seal. The good sealing effect of O shape seal ring depends largely on the proper matching of the size of the O ring and the groove size, forming a reasonable sealing ring, the amount of compression and the amount of tension. Sealing device design, processing, if the O ring compression is too small, it will cause leakage; too much compression will lead to O ring rubber stress relaxation caused by leakage. Similarly, excessive stretching in the work of the O ring will also accelerate aging and cause leakage. The standards of the countries all over the world have strict regulations.
- Q: The difference between piston seal and piston rod seal
- The cylinder is composed of a cylinder block, a piston, a piston rod, a cylinder head and a sealing ring.Piston seal refers to the seal between the cylinder and piston, the seal is bad will affect the performance of the cylinder, sealing groove on the piston
- Q: The seal of the front end of the cylinder and the cylinder, "O" ring, why has it been serrated for some time?,
- It should be the sawtooth at the other end of the pressure chamber.
- Q: Aging test report of rubber sealThat is to say, rubber sealant is how anti-aging
- The factors that cause rubber aging are:(a) oxygen, oxygen free radical chain reaction in rubber with rubber molecules, the molecular chain rupture or excessive crosslinking caused by rubber properties. The change of oxidation is one of the important reasons for the aging of rubber.(b) ozone, ozone chemical activity is much higher than the oxygen, more damaging, it is also the molecular chain was broken, but the effect of ozone on the rubber with rubber deformation and no different. As for the deformation of the rubber (mainly unsaturated rubber), and should be perpendicular to the direction of stress crack the so-called "ozone cracking"; effect on the deformation of the rubber, only surface oxide film without cracking.(c): heat temperature increase can cause rubber thermal cracking or thermal crosslinking. But the basic role of heat or activation. Improve the diffusion rate of oxygen activation and oxidation reaction, thus speeding up the rubber oxidation reaction speed, which is an aging aging phenomenon, heat and oxygen.(d) light: light is shorter, the greater the energy. The destructive effects of rubber from the high energy ultraviolet light can directly cause fracture and cross-linking of rubber chain, rubber due to absorb light energy and produce free radicals, trigger and accelerate the oxidation reaction. The ultraviolet light plays the role of heating. The other feature (light and heat effect) is its main in the rubber surface into. The gum content of high sample, both sides will appear net cracks, the so-called "light outer crack".
- Q: Reasons affecting the tightness of cylinder
- 1, piston and cylinder clearance2, piston ring end clearance3 、 piston ring backlash4 cylinder cylindricity5, valve tightness
- Q: Does the PTFE seal contain plasticizer? Does the silicone seal require temperature during use?
- Polytetrafluoroethylene (Polytetrafluoroethylene), abbreviated as "PTFE", is commonly referred to as "nonstick coating" or "easy to clean material". The material has the properties of acid fast, alkali resistance and various organic solvents. It is almost insoluble in all solvents.
- Q: What is the maximum resistance to the seal in the hydraulic system currently being produced?
- Therefore, in order to improve the sealing capacity, not only rely on seals, good structure is also very important. You say, if the light takes into consideration the seal, there is no problem with the regular 50MPa (usually around 30).
