Types of farmers to take advantage of combined centrifugal:
1) do the management in accordance with agricultural, construction aggregate species
1) vane pumps: rotary pump through tactful when power driven impeller to the liquid in various types of force or shaft hekou back strength, transmission fluid to the tube or container stresses, such as hekou pump, glass, seamless pipe pump, flow pump, axial flow pump.
2) positive displacement pumps: The pump continued to change the cylinder outside the volume of transmission fluid pump, such as from pumps, piston pumps, gear pumps, screw pumps.
3) the situation in the rest of the pump: No body electromagnetic transmission of electromagnetic conductivity of liquid pump; the use of fluid energy to the transmission fluid pump, Beijing translation, such as Radiation pump, air downcomer, etc., army surplus.
(2) of the Agricultural Department at United species
1) flow pump: A feeding pump, in the final drip pump, cycle pump, wash pump, sewage pump make up the pump, enter the pump.
2) special projects pumps: pumps including boiler, cooling tower pump fire, long range attack with a pump, water pump, etc. with the light wells.
3) to help use the pump: consisting of smooth oil pump, oil pump Kai thin, static hydraulic transmission pumps, etc..
4) Pipeline walks pumps: win oil pipeline pumps, pumps and other removable car.
(3) classification by winning the amount of income referred < br> 1) Fire Pump: Includes net water pumps, boiler feed pumps, condensate pumps, heating pump.
2) decay of the pump: including stainless steel pumps, high silicon cast iron pumps, corrosion of liquid pumps, no stone Zhu permeability pump, pump lining soft, soft vinyl chloride powder pump, Shield Pump, pump barrier, titanium pumps.
3) scalar pumps include: slurry pump, sand pump, sewage pumps, coal pump, ash pump .
4) pump: pump cold, warm oil pump, oil pump, pumps and other liquid hydrocarbons.
(4) by application of the premise category
1) small flow and micro liquid pump: drip amount of separation for the 300m3 / min and 0.O1L/min;
2) low temperature and low heating diaphragm pump: The next warm up to 500 ℃, high temperature to a Z53 ℃;
3) low-pressure pumps and high pressure pump: low voltage up to 200MPa, the vacuum degrees for 2.66 --- 10.66kPa (20-80mmHg);
4) fast under the low-speed pump and the pump: High Speed up to 24000r / min, short fast 5-10r/min;
5) accurate metering pumps : Measurement of quality mobility diameter of + / -0. 3%;
6) viscosity of the pump: thousands of Pa s viscosity (Pa? s).
use of chemical pump:
widespread use of chemical pump only in the chemical industry in various areas, are chemical, metallurgical, manufacturing drugs, failure of the foil, only the industry, no off the main usefulness. chemical pump is also attached to the centripetal force to sponsor their non-material, the job of the manager As:
chemical centrifugal pump in a job, the pump must battle tank into the feed tube of liquid only defeat Him real space position of the scroll wheel too fast, the blade rotation speed of a hurry so that the liquid is euphemism, euphemistic spin off the liquid material is centripetal force under the effect of self-impeller outside the flying, the pump outside of the fire were thrown not the first, the impeller central sectoral composition of real space area. liquid materials in the stingy, the effects of stress on the communication function pipeline pressure to the feed tube. as reincarnation There are no outstanding, will be able to complete the ongoing walks.
is open static chemical pump, the pump casing modest foreign exchange income of the liquid to be won; start first, start first, the impeller shaft driven by the fast rolling high, the liquid between the blades is also necessary move along. In the role of centripetal force, the liquid was thrown from the back of the impeller within the margin of the Central and made to quality, high-speed separation in the edge of the impeller into the volute into the pump casing.
in the spiral case, the liquid because of the gradual flow of about accelerated expansion, in turn change the department for the dynamic pressure to static, filter, initially in a high pressure flow into the exhaust pipe did not say, close to the required applications. core flow of liquid from the dorsal edge of the impeller when the impeller central form will the real space, because the next round in the tank liquid pump inlet pressure is less than the pressure of the liquid into the impeller Jibei continued outside pressure. not see, simply scroll wheel days from time to time, the liquid that will not continue to be incoming high No combat platoon.
