Introduction: There are many reasons for the rubber soft joint to bag, some are the problems of raw materials, some are the poor operation of workers when making the ball, compared with some are the problem of time pressure, it is cooked package. There are some problems with insufficient time. They are raw bags. The material of rubber joint is rubber,

Rubber flexible joint There are many reasons for packing, some are the problems of raw materials, some are the poor operation of workers when making the ball, and some are the problem of over time, it is cooked bag. There are some problems with insufficient time. They are raw bags. Rubber joint The material of rubber is rubber. It is very common for foaming rubber to have quality problems. It is inevitable for all products to have quality problems. It is important that when problems arise, we should find solutions in time, and solving problems in time is the key. Rubber soft joint can be used in a certain level of situation, pipeline vibration and noise, in addition, it can also have maintenance function, rubber soft joint can be integrated into a variety of different media through, in addition, it has good corrosion resistance and wear resistance, if the rubber soft joint production processing material quality is poor, or the temperature in the production process is not qualified, these reasons are caused Bubble, the following is a detailed explanation.
1、 Characteristics of rubber flexible joint
1. The rubber soft joint can greatly reduce the vibration and noise of the pipeline system software, and has strong vibration absorption capacity. The problems of socket offset, axial expansion and different centrality of all kinds of pipes are dealt with on the pressure root.
2. According to the different materials, the rubber flexible joint can be made into various varieties such as acid resistance, alkali resistance, corrosion resistance, acid and alkali resistance, high temperature resistance, etc., which can be integrated into a variety of media and environment.
3. The rubber soft joint material is rubber, with good sealing performance, light weight, convenient installation and maintenance, and long service life. However, it can prevent contact with sharp metal instruments to prevent the ball from being punctured.
4. If the rubber soft joint is empty, the expandable support frame shall be used, and the bolts shall be tightened with the top angle method during installation.
5. If the pressure of the flexible rubber joint pipe is too high, use bolts to connect the flanges at both ends.
6. Pressure. To choose according to the pump head, the working pressure of the common joint is 0.6, 1.0, 1.6, 2.5 MPa.
7. Temperature. According to the medium you transport to choose, generally in - 15 ℃ ~ 115 ℃, unique reach - 30 ℃ ~ 160 ℃.
8. Medium. General joint media: air, compressed air, water, sea water, hot water, oil, acid, alkali, etc.
9. If it is more professional, the blasting pressure and vacuum degree should also be considered.
Most of the single joints are single ball.
11. It can cause horizontal, axial and angular offsets, and will not be restricted by pipeline blockage and non parallel flange.
The reason of two blisters in rubber joint
1. For the quality problem of foaming agent, check whether the foaming agent is within the limited period and whether it is qualified.
2. If the plasticity of rubber compound is too low, check whether the plasticity of rubber meets the requirements. Plasticity is beneficial to filling mixing and expanding plasticity pores.
3. If the mixing temperature is too high, the foaming agent will decompose at the initial stage. Check whether the discharge temperature of the mixer is too high, whether the bar temperature is too high, and whether the rubber compound is burnt. Some rubber materials with too high mixing temperature can solve the problem of small quantity and heavy production with foaming agent.
4. If the storage time is too long or the parking temperature is too high, part of the foaming agent will explode and decompose. If the parking time is too long, the rubber compound should be filled and processed in reverse chain.
5. If the curing rate of rubber compound is too fast, adjust the secret formula. Check whether the critical value temperature of curing accelerator is close to the decomposition temperature of foaming agent, and they are in harmony with each other to make the curing speed and foaming rate match each other.
