What are the characteristics and performance of rubber vibration damping
Traditionally, rubber shock absorbers have been widely used in various industries and play an important role. They exist for many times, not only to protect the equipment from vibration damage during continuous operation, but also to minimize the noise of the equipment. With these two points, we pay attention to prove its importance, so that many equipment today can not do without rubber shock absorber.
So what are the knowledge of rubber shock absorber worth understanding and studying? The answer is its characteristics and performance.
1. The rubber shock absorber is highly adaptable and can accept various temperature environments. It is resistant to the corrosion of oil, water and solvent, and is not affected by temperature changes. It can play its original application effect in the environment of upper and lower temperature, large temperature difference, high pressure, high vacuum, strong radiation, violent vibration and corrosion, and can meet the needs of damping, vibration reduction, sealing, filtering, flow saving, sound absorption and noise reduction.
2. The rubber shock absorber has large static shrinkage, low natural frequency, good low-frequency vibration isolation, and will not age or creep, even if it is consumed in large quantities, its characteristics change little. Moreover, its springs have been processed by heat treatment, ED rust prevention, paint baking and other procedures, and the load deflection is 20mm, 40mm, which can effectively eliminate the vibration of mechanical structure. The product control and adjustment are easy, and can effectively eliminate the vibration of the floor.
3. The rubber shock absorber has a long service life. Its design structure is ingenious and reasonable, and it is firm and durable. Its appearance has been treated with rust prevention. The bottom cushion adopts a anti-skid design, and the soft and hard rubber are combined. The side limit rubber is generally soft and wear-resistant, so it can guarantee a long service life.
The above three points are the characteristics and performance of rubber shock absorber. It can be understood that rubber shock absorber has many advantages and functions. As a member of the shock absorber, it also stands out from the crowd.

2. Selection and determination of raw material suppliers
Qualified raw material suppliers shall be determined through selection. The acquisition of a qualified raw material supplier depends on the above evaluation results of the quality assurance ability of each supplier, as well as the production and application, quotation, promise and other factors. Therefore, Tongfeng Pneumatic Butterfly Valve selects several suppliers of the same raw materials to stop comparison, especially when the production and application conditions and the quality assurance ability of each supplier are basically appropriate.
2、 Strictly control incoming raw materials
Buying raw materials from qualified suppliers is not everything. If the supplier is qualified, it only indicates that the supplier has the basic conditions to supply raw materials with relatively stable quality. It is uncertain whether there is a shortage in the quantity of raw materials delivered theoretically and whether the quality can meet the production demand. Therefore, before the raw materials enter the factory, Tongfeng pneumatic butterfly valve strictly controls the incoming quality according to the following requirements.
1. Inspection of raw materials that do not need inspection. The inspection shall be carried out according to the raw material purchase contract, the Certificate of Conformity, the Material Book and other quality certificates accompanying the goods; For single low value consumables that are difficult to issue the corresponding Certificate of Conformity and Material Book, it is necessary to provide samples in advance. Raw materials without Quality Certificate and Raw Material Book shall be rejected for inspection and warehousing.
2. The raw materials to be inspected can be warehoused before being inspected as qualified. Before the raw materials to be inspected are put into storage, the purchased part shall fill in the Inspection Record and submit it to the professional inspection part. After the professional inspection part issues a qualified inspection statement, the qualified statement shall be used for warehousing. If the inspection is not qualified, fill in the Nonconforming Product Record, and fill in the quality information response form to the local response of the quality director in a timely manner, so as to purchase and deal with the return and replacement procedures locally.
3. Timely establish inspection records after warehousing. The storekeeper shall establish the Raw Material Warehousing Inspection Record, which includes the raw material title, specification, type, manufacturer, arrival time, arrival quantity, qualified quantity, inspection time and corresponding quality certificate; In addition, the account and card shall be created according to the type, title and specification of materials for future inquiry and confession.
4. Inspect and dispose of raw materials that are urgently needed or whose quality certification materials are incomplete. For urgently needed raw materials or raw materials with incomplete quality certification materials, it is necessary to fill in the information of quality response in a timely manner and report to the quality director for local response. The quality director will urge the purchasing department for the quality certification materials that have not arrived, and the raw materials will be stored in the unqualified area temporarily according to the warehousing inspection procedures. The inspection procedures can be handled before they are verified to be qualified.
5. The inspection of the appearance quality of materials shall check whether the external packaging of raw materials is damaged or defective, whether the packaging is corroded or leaked, open the box to check the product name, grade, standard type, etc., and check against the commodity certificate and packing list.
6. For the connotative quality problems that only need to be exposed during the installation and application period, the raw material keeper should establish the quality tracking card, adhere to the communication with the production and application units, grasp the first-hand materials, make timely response to the problems found, and notify the supply department to handle according to the rules.
