Stainless steel water tank BDF assembled composite water tank

stainless steel water tankThe sealing performance of BDF prefabricated composite water tanks is one of the key factors in measuring the quality of fire pumps. So, how to control the sealing of the fire pump? The editor will start with the sealing ring of the fire pump and discuss how to check the sealing ring of the fire pump, so as to control the sealing performance well.

　　What are the requirements for inspecting sealing rings? The surface of the auxiliary sealing ring should be smooth and flat, without any defects such as bubbles, cracks, or gaps; The end face size should be uniform; The burrs of the O-ring seal form a 45 degree angle with the working surface.

　　Once bubbles, cracks, etc. appear on the sealing ring of the BDF assembled composite water tank, it indicates that the sealing ring is leaking air. Therefore, in the daily operation of fire pumps, regular inspections should be carried out. Once discovered, they should be replaced or repaired immediately.

　　The hardness of the auxiliary sealing ring should be selected according to the pressure. When the sealing pressure is high, the hardness should be high; Those with lower sealing pressure have lower hardness. Generally speaking, during the production and manufacturing of fire pumps, the manufacturer will have a standard to effectively plan and select the appropriate hardness based on the actual model, purpose, pressure, and other factors of the fire pump. Auxiliary sealing rings are generally made of synthetic rubber material.

　　The compression amount of the auxiliary sealing ring should be appropriate. If the compression amount is too large, the sealing effect will be good, but the friction resistance will be high, the assembly will be difficult, and the ability to compensate for movement during operation will be poor. Low compression, low friction resistance, easy assembly but poor sealing effect;

　　The compression amount of the auxiliary sealing ring should consider its other functions, such as for static rings without anti rotation pins, the static ring O-ring plays a dual role of sealing and anti rotation. The compression amount of the sealing ring should be larger to prevent the static ring from rotating and sealing failure. The O-ring of the moving ring should have a smaller compression amount while ensuring the sealing effect, in order to prevent excessive compression and resistance that cannot be compensated for by floating.

　　How to measure the price of buried BDF composite water tank fire pump? Is it better to have a cheaper fire pump? What is the normal price of a regular vertical fire pump? Customers often express that they have repeatedly purchased fire pumps and encountered three no products, with the common feature being the purchase of cheap fire pumps. Vertical fire pump is a common type of fire pump. XBD-L vertical single-stage stabilizing fire pump set is an extremely common model in the fire pump market. That's why the price of XBD-L vertical single-stage stabilizing fire pump set is very chaotic in the market.

　　The perfect supply model of buried BDF composite water tanks is nothing more than reducing the circulation of intermediaries and preventing the price of fire pumps from increasing several times when they enter the hands of consumers due to the profit margin of intermediaries.
