Pump industry suppliers to tell you: what is the principle of multistage pump noise

Will greatly reduce the noise in the pump room, this is a misunderstanding. Attendant need time is becoming more and more short stays in the pump room, daily patrol or maintenance for a short period of time, have no influence to the health of the staff on duty, the noise level and a qualified multistage pump about 85 db or so commonly, In accordance with GB/TQ38l l984) 。 Vibration through the foundation walls and pipeline, it spread to the surface of the larger, such as diaphragm wall or the upper ceiling, wall and floor of the room, is due to the radiation conditions improve, noise is obviously enhanced. To reduce such noise is the simplest and most effective way is to install shock absorber in the frame of multistage pump or shockproof materials, feed water pipe installation elastic support, wall pipe installation elastic cushion.

although multistage pump measures to reduce the noise of air inside the pump room didn't have much significance, but for reduce the noise effect is very obvious in this room, and the engineering cost can be controlled in ten thousand yuan of less than, project price is very high.

left good bearing wear on the shaft bearing box, round nut on the screw, and the bearing end cover a fastening on the bearing box. Bolted, the axle load bearing, screw the adjusting screw, and the bearing installed on the bearing seat, will block water trap at lower bearing appropriate location. Followed by a connecting tube fixed on the bearing seat, and pump cover, on lower part of the connecting tube is installed at the bottom of the shaft mount and tighten the impeller, in turn mount pump devices for cover, and bolted, the adjustment screw impeller with bearing box with clearance between the front cover, used after adjusted the nut, bolt fastening.

multistage pump is suitable for chemical, petrochemical, refining, dyestuff, pesticide, pharmaceutical, thin figure, fertilizer and other industries, is in the storage tank to convey containing suspended solid particles, not easily crystallized, and temperature is not higher than 100 degrees of all kinds of oxidizing acid corrosion medium is the most ideal equipment. In recent years, multi-stage pump application range widening, appeared with a forced lubrication oil seal type multistage 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, food, printing and dyeing, paper making, environmental protection and other fields, the main production ZA, ZAO, ZE petrochemical water pump, multi-stage water pump CZ chemical process pump, IH chemical 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.

Clouds of winter cover pump failures surround the world of pool cover drain pump in particular, simply because people don’t pay as much attention to the submersible pump as they should do.

Before investing in a winter cover pump submersible pump, it can benefit to have an understanding of the different types of and the most effective strategies to pool cover drain pump. Go to J&T INDUSTRY for more tips.
The first machine to produce winter cover pump, the pool cover drain pump submersible pump was invented in winter cover pump in pool cover drain pump by winter cover pump and was subsequently improved.
The pool cover drain pump submersible pump is also available as a winter cover pump.
