ZX series of centrifugal pump is a self-priming centrifugal pump, it has a compact structure, easy operation, stable operation, easy maintenance, high efficiency, long life and strong self-priming capabilities advantage. No need to install the end of the valve in the pipeline, just keep the pump body before the work stored quantitative dosing, thus simplifying the piping system, but also improve the working conditions. ZX Series Centrifugal Centrifugal Pump I. ZX Series Centrifugal Centrifugal Pump Working Principle ZX Series Centrifugal Centrifugal Pump adopts axial liquid pump structure. The pump body is composed of a suction chamber, a liquid storage chamber, a scroll chamber, a liquid return hole, a gas-liquid separation chamber and the like. After the pump is normally started, the impeller sucks the liquid stored in the suction chamber and the air in the suction pipe together, Within the fully mixed, under the action of centrifugal force, the liquid entrained gas flow to the outer edge of the roll chamber, formed on the outer edge of the impeller a certain thickness of white foam belt and high-speed rotating liquid ring. Gas-liquid mixture through the diffuser into the gas-liquid separation chamber. At this point, due to a sudden drop in flow rate, the lighter gas is separated from the mixed gas and the gas continues to rise through the pump outlet. Degassed liquid back to the liquid storage chamber and re-enter the impeller from the backflow hole, and the impeller gas inhalation from the suction pipe re-mixed World of Warcraft, high-speed rotation of the impeller, and flow to the outer edge of the impeller, with the The process goes on and on, the air in the suction line is continuously depleted until the gas is exhausted, completing the self-priming process, and the pump is put into normal operation. In some pumps the bottom of the bearing body also has cooling chamber. When the bearing heat causes the bearing body temperature rise over 70 ℃, through the cooling room at any one of the coolant pipe fittings, cooling fluid injection cooling. Pump inside to prevent the liquid from the high-pressure zone to the low-pressure zone leakage seal mechanism is the front and rear seal ring, the front seal ring mounted on the pump body, the rear seal ring mounted on the bearing body, when the pump running seal ring wear to a certain extent, and Affect the pump efficiency and self-priming performance, should be given replacement. Second, ZX series of centrifugal pump water purification applications 1, for urban environmental protection, construction, fire protection, chemicals, pharmaceuticals, dyes, printing and dyeing, brewing, power, electroplating, paper making, oil, mining, equipment cooling, unloading oil tankers, etc. 2 For water, sea water and with acid, alkalinity of the chemical medium liquid and paste with a general paste (medium viscosity ≤ 100 PCT, solid content up to 30% or less). 3, equipped with rocker-type nozzle, the water rushed into the air, dispersed into small raindrop spray, farm, nursery, orchard, tea plantations a good tool. 4, can be used with any type, size filter press, the slurry sent to the filter pressure filter the best matching pump.

stone art

The history of stone carving can be traced back to the middle of the Paleolithic Age, which is about 120000 years ago. Since then, stone carvings have been handed down to this day. In this long history, the creation of stone carving art has been constantly updated and improved. In different periods, there were great changes in the types and styles of stone carvings; Different needs, different aesthetic pursuits, different social environments and social systems are restricting the development and evolution of stone carving creation. The history of stone carving is not only the history of art, but also the history of rich cultural connotation. It is more vivid and real human history.
