The wide application of rubber fluorine chemical pump

rubber fluorine chemical pump is widely used in energy, metallurgy, chemical industry, textile, papermaking, hotels, bathrooms, hotels such as boiler, high temperature hot water pressure loop and urban residential heating circulation pump, using temperature below 240 ℃.

because lining fluorine chemical pump is widely used, lining fluorine chemical pump is a great variety of products on the market, quality is good and bad are intermingled, the price of the good and bad are intermingled, about how to choose and buy suitable lining fluorine chemical pump has become the user needs to solve the problem. Here are several ways to help you choose the correct products.

user department shall supply all kinds of original records, contains the actual operating station, using the scale, applying condition, parts damage early faults and fault records, records and other original records. Studied the typical failure and parts, and put forward the improvement measures and countermeasures. Of equipment the flaws in the original design, the manufacture put forward reasonable improvement suggestion, and adopt measures to improve maintenance. Initial cost and the using effect of skills and economic analysis and review. Analysis and deal with the collected at the beginning of the use of materials.

rubber fluorine chemical pump self-priming principle: because the pump shell's special design. Centrifugal pump seal function is higher than ordinary centrifugal pump, the motor after closed does not take the initiative to empty the water in the pump housing. Motor driven turbine at high speed, and quickly form a negative pressure in the pump ( Vacuum) 。 With atmospheric pressure pumping water to the pump shell, and the centrifugal lift. Therefore, lining fluorine chemical pump suction size will not be more than one atmospheric pressure, about 11 meters.

about static seal, only two types of gaskets and sealing ring, sealing ring used in the o-ring. About dynamic seal, chemical pump packing seal is scarcely used, mainly mechanical seal, mechanical seal can be divided into the single face and double face, equilibrium and non-equilibrium model. Balance type is suitable for the seal of high pressure medium ( Usually refers to greater than 1. 0 mpa pressure) 。 Double side confidential letter is mainly used for high temperature, easy to crystallization, viscosity, particle concentration and toxic volatile medium, double-headed confidential sealing spacer fluid injection should be sealed cavity. Pressure is generally higher than medium pressure 0. 7 ~ 0. 1mpa。

when general pump device, the height of the page, slightly higher than the pump lining fluorine chemical water pump is a device to where is higher than the page, have a certain function of self-priming, as long as there is lining fluorine chemical pump, ZX water ZW lining fluorine chemical pump no blockage, WFB active lining fluorine chemical pumps, etc.

rubber fluorine chemical industry principle is to use the velocity pulse of water water pump, the impeller will drive pump impeller pump to the Banks of the river. Lining fluorine chemical pump was thrown into a river to pump water, but it must be the rapids or cracks.
