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？
We have established the international advanced quality management system every link from raw material to final product we have strict quality test; We resolutely put an end to unqualified products flowing into the market. At the same time, we will provide necessary follow-up service assurance.
- Q:Do some machinery, bearings, wind power equipment, machine seals, agents? Are there any prospects for the next few years?
- Equipment manufacturing industry is China's manufacturing base in the next twenty years, the pillar of the world, all the development of this industry space is great, specific to a subdivision of the prospects?,
- Q:What is the function of the seal?
- The function of the seal is to close the gap in the tank and to prevent dust, sand and other dirt from invading the inside of the chamber, but if installed or improperly used,
- Q:What's the function of the sealing ring?
- Mechanical seal work should pay attention to the problem1, installation notesA, take great care to avoid installation errors in installation(1) to tighten the gland should be aligned in the coupling bolts should be uniform, to prevent the end cap oblique, with feeler check, the error is less than 0.05 mm.(2) clearance check the gland and the shaft or shaft diameter (i.e. concentricity), around to evenly, not more than 0.01 mm check with the feeler the tolerance.B, spring compression amount should be carried out according to regulations, not allowed to have too large or too small phenomenon, requiring 2 millimeters of error. Excessive assembly increases the face to face pressure, and the other speeds end wear. Too little will cause less pressure than sealing.C, the ring should be installed to ensure flexible movement on the axis, the moving ring pressure to the spring, it should automatically bounce back.
- Q:What kind of material seals can withstand ammonia, -40 degrees to 200 degrees?
- 2, because the molecular structure contains fluorine atoms, the influence of electron absorption group, PTFE exhibits high chemical stability, almost resistance to all acids, bases and other chemical substances invasion.
- Q:How can the tapered roller bearings be sealed?
- There are many kinds of tapered roller bearings, I wonder if it is oil lubrication or grease lubrication? Dustproof or anti leakage?
- Q:What's the seal water? What about the water seal?
- The function of sealed water is:1 high pressure water, water pump inside, even after the seal but there is still a certain pressure, in order to keep the water pump in the water through the shaft and seal gap between the leakage from the condensate pump outlet, or a water seal water in addition to lead as saline parent tube!2, water supply and the water pump is a high temperature water, the temperature will be passed to the pump body through a rotating shaft or bearing metal pump, the bearing temperature, in order to control the temperature outside so the seal also plays a role in cooling water.
- Q:How about the sealing ring for the piston rod seal?
- The composite sealing ring, such as K type stepseal, it consists of two distinct components: one is to join the ladder bronze seal filler with PTFE (main seal), the other is a O shaped sealing ring (elastic element and side seal). The combination sealing ring (K type) has the characteristics of low friction resistance, no creeping at the start, low leakage and wear resistance. The combination of the sealing ring avoids the contact between the metal, improves the supporting ability, bears the certain lateral force, the small friction force, and is suitable for the high voltage and high speed system, and has been proved by the experiment.
- Q:What kind of performance requirements should the rubber seals meet?
- physical propertyThe seal is generally divided into static sealing and dynamic sealing in two forms, one of the typical example is the static sealing pipe sealing, after installed in the pipeline, the pipeline movements will cause the rubber seal (circle) and slow motion interface, while the rubber is in the static state of compression. Because most of the pipeline buried underground, so some outside factors such as temperature, ultraviolet radiation and other basic oxidation on aging seal has no effect, at this time of the rubber material can require a higher compression performance, others can reduce the requirements; a movable seal used in the process of rubber seal should have different physical properties. The representative of the dynamic seal valve seal, the sealing process, the addition of rubber stress, the surrounding environment is complicated, so the rubber seal in the process due to excessive squeeze decreased elasticity, or because of wear caused by leakage. Therefore, in this process, we must according to the seal between the valve sealing parts in the process of the use of different materials used require different physical properties, and effectively solve the rubber seal and deformation, because of the long-term use of sealing effect reducing problems.
- Q:What are the material requirements of the valve sealing surface?
- Sealant, liquid sealant, anaerobic adhesive gasket, pipe connection, thread sealInorganic materials, flexible graphite, natural graphite gasket, soft packing, sealing partsCarbon graphite baking carbon, anodized graphite, mechanical seal, hard packing, power seal, gap sealEngineering ceramics, alumina ceramics, talc ceramics, cermets, silicon oxide and chromium borideMetal, nonferrous metal, copper, aluminium, lead, zinc, tin and its alloy gasket, soft packing, mechanical seal, labyrinth seal, hard packing and gap sealFerrous metal, carbon steel, cast iron, stainless steel, surfacing alloy, spraying powder gasket, hard packing, mechanical seal, piston ring, gap seal, dust-proof seal, full closed seal, forming fillerTungsten carbide, cobalt carbide, tungsten cobalt titanium carbide mechanical sealPrecious metals, gold, silver, indium, tantalum, high vacuum sealed, high pressure sealed, low temperature sealedThe performance of the sealing material is an important factor to ensure effective sealing, selection of sealing materials, sealing element is mainly based on the working environment, working medium such as temperature, pressure, use and movement etc.. The basic requirements for sealing materials are as follows:I have certain mechanical properties such as tensile strength, elongation, etc.;
- Q:What's the difference between the oil seal and the seal?
- The placement of the skeleton has strict requirements, and the standard and specifications of the products are different. Of course, the prices are more expensive than those made in China
