FAQ

What's the difference between a centrifugal pump and a centrifugal pump? What are they used for?

Centrifuges are generally used to classify liquids of different densities in liquids.

Rules for operation of centrifugal pumps

Working principle and process flowWorking principle: when the drive motor with high-speed rotating impeller, full of fluid in the pump body under the action of centrifugal force, was thrown from the impeller center to the outer edge of the impeller, in this process, the fluid energy, improve the pressure can, at the same time also increases the energy flow rate increase. The liquid from entering the pump impeller shell, the liquid flow gradually widened, the liquid velocity decreased gradually, which will be part of the kinetic energy into pressure energy, which further improves the static pressure of liquid, and liquid with high pressure in pressure pipeline. When the liquid from the leaves out when the impeller center creates pressure and low pressure than the out plane is big, under pressure drive, liquid is continuously from the center of the impeller suction, with the pressure of continuous discharge.

What's the word "pump"? Is that what advocates mean?RT

What is a "fan"?In recent years, the term "fan" often appears on the newspaper Web page, whether it is a team, a singer, a sports car and a toilet, all of which have their own fans

How many concrete pump tube diameter

Different pipe diameter is different, most of the 125, there are 150. Now we have the smallest pump on the market, with a pipe diameter of 100.

What's the submersible pump?What is a submersible pump, and what about it?

Deep well submersible pump is a fountain, drinking water transportation, irrigation, hot springs, high-rise transport facilities, etc., deep well submersible pump excellent performance, so widely used in various fields.

Why is the submersible pump tripped on an electrical switch?There is no electrical leakage protection, directly connected to the circuit breaker, and when the switch on, the circuit breaker jumpedI checked the line is good, the pump did not break down, is not the water pump?

Calculate or refer to the water pump nameplate that the normal operating current, according to this data exchange switch.2) with 500V shaking table, measuring the cable, motor insulation is in line with the requirements

Variable flow pumps are variable pumps

To be exact, variable pump means variable displacement. Because if the displacement does not change

What are the important parameters of the pump?

Because the lift refers to the effective energy, pump output unit of heavy liquid obtained from the pump so that the product of head and the mass flow rate and acceleration of gravity, is the effective energy output from the pump in unit time of liquid -- effective power pump:Pe= P gQH (W) = QH (W)In the p - density of liquid pumping (kg/m3);Gamma - pump heavy liquid delivery (N/m3);Q - pump flow (m3/s);H - pump lift (m);G - gravitational acceleration (m/s2)The shaft power P and effective power Pe is the difference of power loss in the pump, the size of the pump efficiency to measure the efficiency of the pump. As the effective power and shaft power ratio, with ETA said.
