Pump industry suppliers - Chemical pump emergency shutdown steps in mixed flow pump

chemical centrifugal pump parsing and emergency shutdown in mixed flow water pump steps:

the performance of the centrifuge is inertia. Water droplets on the umbrella, for example, when the umbrella turning slowly, water droplets turn will follow the umbrella, it is because the umbrella with droplets of friction as to the result of the centripetal force of the water droplets. But if the umbrella rotational speed, the friction force is not enough to make water droplets to do circular motion, then the water will be separated from the umbrella to the outer edge. Like to use a rope to pull the rocks do circular motion, if too fast, the rope will disconnect, stones will fly out, this is what is called a centrifuge. Chemical mixed flow pump is designed according to this principle, high-speed rotating impeller blade drive the water rotation, throw the water, so as to achieve the purpose of conveying.

mixed flow pump emergency stop chemical steps:

1) rapid press stop button, the water pump stop; Control the import of large tank liquid level close valve, cooling water, lubricating oil and so on;

(2) close the outlet valve, after waiting for the pump stopped disc pump 2 ~ 3 ring; If temperature heat conduction oil pump and so on to pay attention to safety.

chemical is mixed flow pump according to the company for domestic environmental protection requirements, cooperation with research institutes to develop high-tech products, completely solve the chemical industry operation, risk, drip of environmental protection. Its structure is single stage single suction horizontal centrifugal pump.

chemical mixed-flow water pump main advantages: applicability is wide and no leakage corrosion resistance, wear resistance, flexible and jam.

chemical mixed-flow pump applicable industry: no leaking chemical pump is widely used in chemical industry, metallurgy, oxidation, environment protection, etc. Can deliver any solid content more than 40% of the concentration of acid, alkali, salt, especially the inflammable, explosive, volatile or poisonous, precious liquids.

chemical mixed-flow pump according to medium selection?

general metal nitrate in the nitric acid corrosion soon. Stainless steel is the most widely used of nitric acid resistant material. At room temperature for various concentration of nitric acid has good corrosion resistance. It is worth mentioning that molybdenum stainless steel in nitric acid corrosion resistance is superior to the ordinary stainless steel not only, sometimes even worse, for high-temperature nitric acid, usually use of titanium and titanium alloy.

acetic acid is one of the strongest material corrosion in organic acids, ordinary steel in any concentration and temperature will severely in the acetic acid corrosion. Stainless steel is a kind of excellent resistance to acetic acid material, 316 stainless steel containing molybdenum can also be used in high temperature and dilute acetic acid steam, high temperature, high concentration of acetic acid and other corrosive medium, can choose high alloy stainless steel pump or fluorine plastic pump.

pump industry suppliers is the collection scientific research, design, production, management, services for the integration of production enterprises, the products are widely used in petroleum, chemical industry, metallurgy, electric power, mining, coking, medicine, printing and dyeing, food, paper making, environmental protection and other fields. The company has a modern self-priming pump performance testing means, equipment is excellent. Main production ZA, ZAO, ZE petrochemical pump, CZ chemical process pump, chemical mixed flow pump, forced circulation pump, SPP chemical mixed-flow pump of 28 kinds of material, 30 series more than 1000 specifications special alloy chemical pumps, valves, stainless steel pipe, fluorine pipe parts. 。
