Q:What are the better domestic rubber parts, seals ah?
Used are imported materials, whether it is pre-sale or after-sale cooperation degree is relatively high. There is no quality problem
Q:Classification of sealing strip by use
Seals can be divided into two categories: static seal and dynamic seal.Static sealStatic seals are mainly gasket seal, sealant sealing and direct contact sealing three categories. According to the work pressure, static seal can be divided into medium and low pressure static seal and high pressure static seal. Low and medium pressure static seals are usually made of soft and wide width gasket. High pressure and static seals are made of hard material and metal gaskets with narrow width.Dynamic sealDynamic seals can be divided into rotary seal and reciprocating seal two basic types.OtherAccording to the seal of the relative movement of the parts is divided into sealing contact, contact and non-contact seal; according to the seal and the contact position can be divided into circumferential seal and the seal, the seal is also called mechanical seal. The centrifugal seal and spiral seal in the dynamic seal are sealed by the power of the medium when the machine is running, so it is sometimes called the power seal.According to the type of sealing structure, sealing mechanism, seal shape and material, the seal can be classified according to table 29.2-1.
Q:How to prevent the metal from sticking to the gasket?
It is better to use torque wrench when sealing gasket is pressed. For large bolts and high strength bolts, it is better to use hydraulic tightening devices. The tightening torque shall be calculated by calculation according to the given gasket. The size of the hydraulic pressure of the hydraulic tightening device shall also be determined by calculation.5. When installing the gasket, tighten the nut in sequence. However, the design value should not be screwed once. Generally should be recycled at least 2~3 times so that the gasket can be evenly distributed.6, the flammable and explosive medium pressure vessel and piping, replacing gasket should be used to avoid security tools, tool and flange bolts or collide, sparks, causing a fire or explosion accident.
Q:How are ceramic and metal sealed joint?
The sealing parts should be selected according to the different line speed, sealing medium, temperature, pressure and direction.
Q:What is the operation of the seal company sulfur chemical?What is the specific work? Is there any danger and harm?
Operator vulcanizing machine is the production of sealed products, the general operation of the vulcanizing machine, with the production of mold. The danger is that rubber products will generally have some taste, the body is not very good,
Q:The difference between piston seal and piston rod seal
Piston rod seal refers to the seal between the piston rod and the cylinder head. If the seal is not good, it will leak oil, and the sealing groove is opened on the hole.
Q:What kind of performance requirements should the rubber seals meet?
Hygienic propertyRubber products is the basic appearance of bread wrapped in a layer of rubber material, the appearance is basically the same, but the internal quality will have great differences, in the process of sealing performance using rubber seal strengthening of certain products, we must avoid pollution problems, so in the use of rubber sealing, material requirements, must be used non-toxic materials and prohibited the use of recycled rubber seals, and suitable for drinking machine and other products on the GB/T17219-1998 must pass "drinking water distribution equipment and protective materials safety evaluation standards" or BS6920:2000 "through the test of non - metallic products non-toxic effects on water quality for inspection of the body contact".Above is the performance requirements for rubber experts to introduce you to the Luo Geng mechanical seals are used to seal materials, there are various types, in use to different products, we need to use the seal will be different, but most of the time to see in addition to seal the dimensions, we see the seal of the materials used, whether has the properties we need, so as to determine whether the rubber seal products.
Q:Seal manufacturers as agents, how about money?
The outlook is good, considering whether it is just a question of need, the size of your market. Gasket, packing manufacturer
Q:Mechanical, I often need to use seals, when used with a sudden do not know the specifications, size,
Strongly recommended "seal design manual" for the first comprehensive, detailed description of the seal design tool books, suitable for mechanical designers, mechanical engineers access and reference. From the actual demand of the mechanical design personnel, emphatically introduces all kinds of typical sealing principle, structure, performance, performance and application, how to design the structure according to the specific conditions of use to a reasonable choice of sealing materials and sealing type and. "Seal design handbook" (Paperback) basic information: Author: Chang Degong Fu Ping price: 56 press: Chemical Industry Press; First Edition (April 1, 2009) Paperback: 332 pages of text language: Chinese format: 16 ISBN: 9787122046826 bar code: 9787122046826 product size and weight: 25.6 x 18.2 x 1.6 cm; 558 G. "The contents of the seal design manual" from the practical mechanical design of the detailed and systematic exposition of the mechanical seal, hydraulic and pneumatic seals, gaskets, packing seal, rubber seal, labyrinth seal, spiral seal, magnetic fluid sealing, pressure sealing and other common seal principle, basic structure, characteristics, performance
Q:Does the PTFE seal contain plasticizer? Does the silicone seal require temperature during use?
Silicone rubber is much better than ordinary rubber in heat resistance. It can be used almost always at 150 degrees without performance changes. It can be used continuously for 10000 hours at 200 degrees, and can be used for a period of time at 350 degrees. The utility model is widely used for occasions requiring heat resistance, a thermos bottle sealing ring and a heat-resistant handle of a pressure cooker ring.
