ZW synchronization row suction priming pump

About synchronization row suction ZW self-priming pump priming pump works: The pump housing before the pump starts to fill with water (or water pump housing itself there). After starting the high-speed rotation of the impeller channel impeller in the water to the scroll, then the entrance to form a vacuum, so that the water Check the door open, the intake air tube into the pump and reaches the outer edge of the channel by the impeller. Priming pump is self-priming centrifugal pump, it has a compact structure, easy operation, smooth running, easy maintenance, high efficiency, long life, and have strong self-priming capacity. Line without having to install a foot valve, pump body before work just to ensure that there is quantitative priming can. Self-priming pump different liquids of different materials may be used. ZW synchronization row suction structure type self-priming pump priming pump a lot of structure, in which the molten salt pumps, vacuum pumps, liquid pumps, metering pumps, gear pumps, corrosion resistant pumps, acid pumps, fire pumps to the rotational direction of the flow. Then with the right backwater hole stream water confluence, along spiral flow. Since the liquid in the volute continue to impact the cascade, constantly being crushed impeller, on strong mixing with air to produce air-water mixture, and continue to flow so that air and water can not be separated. The mixture was stripped in the tongue volute outlet, into the separation chamber along the short tube. It is separated in the separation chamber air out from the outlet pipe to drain, and the water is still flowing through the impeller backwater hole around the outer edge, and mixed with the air suction pipe. This cycle repeated gradually sucked the air pipe drained the water into the pump, complete self-absorption process. Self-priming pump diaphragm pump sewage pump gear pump screw pump the same, the difference is only the outer edge of the backwater does not flow to the impeller, and the impeller inlet flow. Self-priming pump in the mix at the start, the return valve must be opened before the bottom of the impeller, the pump so that the liquid flows back into the impeller inlet. Water in the role of high-speed rotating impeller is mixed with the air intake pipe to form a mixture of gas and water discharged to the separation chamber. Here the water and from the air exhaust recirculation valve returns to the impeller inlet. This is repeated until the air is drained, smoking Sheung Shui in the mixed style of pump, works with external mixing self-priming. Priming pump is self-priming height, before sealing the gap with the impeller, the number of revolutions of the pump, the separation chamber liquid height and other factors. Impeller before sealing the smaller the gap, the greater the self-priming height, generally taken to be 0.3 to 0.5 mm; when the gap increases, in addition to a high degree of self-absorption decreased, the pump head, the efficiency decreased. The self-priming pump impeller height with the peripheral speed u2 increases, but the maximum self-priming height, increase the number of revolutions will no longer increase the height of self-absorption, this time just to shorten the self-absorption time; when the number of revolutions When the fall, along with the decline in self-priming height. In other conditions remain unchanged, self-priming height also increases storage height increases (but not exceed the height of the separation chamber optimum storage). In order to better enable self-priming pump water mixed gas, the impeller blades to be less, so that the cascade pitch increases; and should adopt the semi-open impeller (or impellers wide channel impeller), which is more facilitate deeper penetration of the impeller backwater Cascades. Most self-priming pump with the engine package, mounted on a movable trolley, suitable for field work.

Pump from the suction chamber, liquid storage room, volute chamber, liquid hole, gas-liquid separation chamber, etc., after the normal starting pump impeller suction chamber of the stored liquid and suction line of air sucked together, and the impeller be completely mixed within, the centrifugal force, the liquid entrained gas flow to scroll outside edge is formed with a certain thickness of white foam and high-speed rotating liquid ring on the outer edge of the impeller. Gas-liquid mixture into the gas-liquid separation tube by diffusion chamber. In this case, the flow rate suddenly decreases, the lighter gas is separated from the gas-liquid mixing out, the gas is discharged through the pump Tukou continue to rise. Degassed liquid back to the liquid chamber by the return holes again into the impeller, and the impeller inside the suction from the suction line gas is mixed again, under the effect of high-speed rotation of the impeller, and the flow impeller tip .... ... As the cycle of this process continues, the suction pipe in the air continuously reduced until exhaust gas, complete self-absorption process, the pump will be put into normal operation. In some pump at the bottom of the bearing body also has a cooling chamber. When the bearing bearing temperature rise caused by heat over 70 degrees, it shall be liable to the cooling chamber by any of a coolant pipe fittings, into the coolant circulation cooling. Inside the pump to prevent liquid from the high pressure zone to a low pressure area around the leak sealing means is a sealing ring, before sealing ring mounted on the pump body, after sealing rings mounted on the bearing body, when the long-term operation of the pump seal ring wear to a certain extent, and affect the efficiency of the pump and self-priming performance, should be given replacement. 7ZW synchronization row suction action according to the principle of self-priming pump priming pump types are divided into the following categories: 1. liquid mixing formula (including mixed-type and outer recirculation); 2. Water ring wheel; 3. JET (including liquid jet and gas jet). Working gas-liquid mixing process is self-priming pump: Because of the special structure of the pump priming pump, after the pump stops, pump memory a certain amount of water, the pump starts again due to the rotation of the impeller, suction line of air and water mixed well, and was discharged to the gas-water separation chamber, the upper chamber of the gas-water separator gas spill, the lower the water is returned to the impeller, suction line again and remaining air mixing, until the gas pump and the suction tube completely discharged, complete self suction, and normal pumping. Wheel self-priming pump is a water ring water ring pump impeller wheel and combined in a single housing, with water ring round the gas discharges, to achieve self-absorption. When the pump is working properly, it can cut off the water wheel and pump impeller ring channel through the valve and release the liquid water inside the ring wheel. Jet pump, a combination of centrifugal pumps and jet pumps (or jet) is made, relying injection device, creating a vacuum to achieve suction at the nozzle. By supporting the pump motor power machine types into supporting self-priming pump priming pump and diesel engines. According to achieve self-priming structure and working characteristics can be divided into slippery, external Slide, water and other types of ring wheel. There are direct drive transmission mode (including an inner shaft) and belt drive. Inlet diameter 25 to 200 mm. 8 Selection 1 to strict procedures available pumps. When you purchase the pump but also factual, only three certificates complete phase-out in order to avoid the purchase of products and inferior products. 2, 3 self-priming pump purchase to local conditions, to choose the appropriate pump exceeded. Determine the pump type, to consider their economic performance, with particular attention to and supporting the head and flow rate of the pump power of choice. It must be noted on the label of the pump head (total head) and water lift (the actual head) to use when there is a difference, it is there will be some resistance losses due to water flow through pipes and tubing at nearby input. Therefore, the actual head than the general 10% to 20% of the total head low, the water is also reduced. Therefore, the actual use, can only sign the note of 80% to 90% of head and flow estimates, pumps supporting dynamic selection, press on the label of the power of choice, in order to pump start fast and safe to use, the power machine Power can also be slightly larger than the pump power required is generally higher than 10% is appropriate; if the existing power, buy pumps, you can press the power machine of power purchase with matching pumps
