Rubber expansion joint pump room selection advantages
The rubber expansion joints used in the secondary booster pump room in winter heating are made of high temperature resistant materials to effectively ensure full heating. The criteria for full heating: one of the issues that need to be considered when using various accessories for heating booster pump room is: whether the product is high temperature resistant, can it withstand high temperature, how much working pressure can it withstand if it can withstand high temperature, generally high temperature resistant rubber expansion joints are very high, there are many dealers in order to solicit a single, take the ordinary over water rubber expansion joints to the site to send, so that the booster pump room use, once the problem, the temperature are very High, so it will be very dangerous, all, the booster pump room inside the use of rubber expansion joints using high temperature resistant rubber material production before the full heating standards can be achieved. Generally are purchased natural rubber soft joint over water products, there is no guarantee of quality, over water rubber is natural rubber, the temperature is generally below 80 degrees, if the customer use the room temperature is 70 degrees, then it is not safe, but also worried about problems, fear of leakage, serious will also it, all we are better to be careful. When purchasing must be recognized as authentic manufacturers products, so that there will be full protection. This rubber soft joint can reduce vibration and noise, and can play a compensating role for thermal expansion and contraction caused by temperature changes, and is widely used in various piping systems.
 
 
There are many different ways to classify the heating system. According to the different heat media, it can be divided into: hot water heating system, steam heating system, hot air heating system; according to the different heat sources, it is also divided into three categories, such as heating by thermal power plant, heating by regional boiler room and centralized heating. According to the different circulation power of the system, the hot water heating system can be divided into natural circulation system and mechanical circulation system. According to the different ways of supply and return, the hot water heating system can be divided into single pipe system and system. According to the different ways of pipe laying, the hot water heating system can be divided into vertical type system and horizontal type system. According to the different temperature of hot coal, hot water heating system can be divided into low temperature heating system (water supply temperature t<100℃) and high temperature heating system (water supply temperature t≥100℃).
 
To choose the suitable material of rubber joints according to the temperature: -20°C~80°C choose natural rubber, which is. For the common rubber joint material, basically no. This rubber material is used in case of special requirements, with good pressure change performance, wear resistance and tensile performance. -20°C~120°C EPDM rubber is used. This rubber material can be vulcanized by organic peroxide up to 120°C, with high temperature steam resistance and low gas permeability. Not only this kind of rubber also has certain resistance to weak acid and alkali performance, for some slight degree of acid and alkali installed environment has good adaptability. -25℃～180℃ choose rubber, excellent high temperature resistance, good aging resistance,... Good vacuum performance, excellent mechanical properties, good electrical properties choose rubber expansion joints when the pressure, weight, temperature are required to detect and select, no matter which model, which size of flexural rubber joints are very common, especially for heating equipment. According to the connection method, there are three types of rubber joints: loose flange type, fixed flange type and threaded type; according to the structure, they can be divided into five types: single sphere, double sphere, reducer, eccentric reducer, curved sphere and fan coil. It is composed of inner and outer layer of rubber, cord fabric layer and steel wire ring, which is vulcanized and then loosely combined with metal flange or parallel joint. This rubber joint can reduce vibration and noise, and can compensate for the thermal expansion and contraction caused by temperature changes.
