How does the fire pump clamp rubber soft joint play a compensation role?

The hoop is made of stainless steel and has corrosion resistance. The point is from DN50-DN500mm, and the installation length refers to JGD (KXT)-Df or designed according to the needs of the connecting customer. Clamp rubber soft joints are classified according to one of the types of connection methods. They are combined with threaded clamp rubber soft joints and flange clamp rubber soft joints to be called the three major connection methods of clamp rubber soft joints. Clamp rubber soft joint is a kind of pipe fitting that is convenient to install. In some low-pressure pipelines, the usage amount of KKT type clamp rubber joint even exceeds the usage amount of flange connection type clamp rubber soft joint. KKT type clamp rubber soft The joint can also be transported in various special materials according to the change of its own material. It saves flanges and bolts and saves engineering expenses. No flanging is required at the nozzle of the product, which simplifies work efficiency. It simplifies installation and maintenance work and improves work efficiency. High-efficiency parts, and recommend the use of low-resistance rubber flap check valve and straight cylinder clamp rubber soft joint, which better solves the water supply problem of the fire water tank.

According to the performance parameters of the fire pump, the installation height, the shape of the suction pool, the physical characteristics of the circulating water, the layout of the inlet pipe, etc., the reasons for the leakage of the rubber soft joint of the clamp in the thermal power plant are discussed, the harm caused and the solution. Fire pumps are one of the important auxiliary equipment of thermal power plants. Compared with the fire pumps of condensing power plants, they are more prone to cavitation. Most of the fire pumps of thermal power plants are equipped with soft rubber joints for acid and alkali resistant clamps, and there is cavitation. Some cavitation occurred after two or three years of operation, some occurred after more than a year of operation, and some had cavitation at the beginning of operation. There are many factors that cause cavitation in fire pumps. In summary, they are mainly The following three aspects: one is the reason of the pump itself; the other is the design of the pump and piping system; the third is the improper operation of the power plant operators. The structural composition of acid and alkali resistant rubber flexible joints: inner rubber layer, reinforced fabric layer, steel wire frame layer, outer rubber layer, flange and flat joint, its compressive strength calculation refers to the calculation formula of cord wound hose.
