Design
Single- or multistage centrifugal pumps in ring-section design, single entry; for vertical and, depending on the number of stages, angled and horizontal installation; mixed flow hydraulic systems available with reduced impeller diameters; driven by submersible motors. Suction casing fitted between pump and motor, equipped with strainer to protect the pump from coarse particles in the fluid. Permissible sand content in the fluid: 50 g/m³. Pumps with non-return valve or connection branch on option.
Applications
pumping clean or slightly contaminated water in general water supply, irrigation and spray irrigation systems, lowering and maintaining ground water levels, pressure boosting, emergency water supply, as well as mines and fountains etc.

Q:Double floor sewage pump circuit diagram of a small problem: Q 2, SA and SS are select switches, and different positions indicate the same difference between the two nodes. SA hits the left position 13, 14 to connect, hits to the right position 21, 22 to connect. SS hit the middle position, 5 and 6 turn on, 7 and 8 turn on; hit the right position; 1 and 2 turn on; 11 and 12 turn on; hit the left seat; 9 and 10 turn on; 3, 4 turn on.

Q:Working principle and structure of external gear pump: When the meshing teeth on one side of the suction chamber are gradually separated, the volume of the suction chamber is increased, and the pressure is lowered, and the liquid in the suction pipe is sucked into the pump; the suction liquid is divided into two parts to be pushed into the discharge chamber by the gear in the alveolus. When the liquid enters the exhaust chamber, the liquid is squeezed and discharged from the exhaust chamber into the discharge pipe because the teeth of the two gears are continuously engaged. The driving gear and the driven gear keep rotating, and the pump can continuously inhale and discharge the liquid. The pump body is equipped with a safety valve, when the discharge pressure exceeds the required pressure, the delivery liquid can automatically open the safety valve, so that the high-pressure liquid returns to the suction pipe.

Q: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.

Q:What is the "variable" of a variable pump? Is the displacement change or the flow change? Thank you: There are many ways to change the variable pump flow: by changing the eccentricity to change the piston stroke length (radial piston pump, the frequency change principle) motor speed to adjust the flow (such as gear pump flow control principle).

Q:How can I buy a pump?: 3 、 mechanical requirements of high reliability, low noise, vibration.4, the correct calculation of pump procurement costs, the pump manufacturer to inspect, requiring good quality equipment, good after-sales service, spare parts can be timely supply.The micro pump and the motive of the mechanical energy or other external energy transmitted to the liquid, the liquid energy increase, mainly used to transport liquids including water, oil, alkali liquid, emulsion, suspension emulsion and liquid metal, but also transport liquid, gas mixtures and liquids containing suspended solids.The technical parameters of pump performance include flow, suction, lift, shaft power, water power, efficiency and so on.

Q:What is the relationship between the minimum suction vacuum of a pump and the required cavitation?: Suction is allowed to pump the vacuum from the distance from the inlet, which is part of the field installation.The manufacturer of cavitation allowance is closely related to the design and process of pump. Estimation formula: cavitation allowance =10.33 meters - allow suction of -0.5 meters (safety).

Q:Is the sewage pump the same as the mud pump?: The upstream return speed of the washing fluid is required to remove the cuttings and rock powder from the drill in a timely manner from the bottom of the hole and reliably carry it to the surface. Through drilling and extraction, mud can be obtained at the bottom.

Q:What is the lift off the dead center point? This is a straight mark about the water pump. What is the function and the relationship between the design head and the pump head? ThanksWhat exactly is the dead point lift? What's the function of this indicator?: In a dead head will be relatively high, the main downstream equipment and pump, if a dead head high, so the design pressure of the pump needs downstream equipment will be relatively large, resulting in the cost increases, so close a better head lower dead point.

Q:Do you have a suction pump higher than 9 meters?: This screw self-priming pump suction process can be more than ten meters or more, my family is using this

Q:What are the ways of hydraulic pumps?: Hydraulic pump is a power component of hydraulic system. It is driven by an engine or an electric motor. It draws oil from the hydraulic tank to form a component of the pressure oil which is sent to the actuating element.
