How a Pump Works
The pump is driven by an AC or DC motor
In front of the motor is a valve assembly containing two to five valve pump chambers. Each valve chamber has a diaphragm behind it in the lower pump housing. As the motor shaft turns, an internal cam positioned behind the diaphragms causes the diaphragms to be pushed forward, then back in a continuous sequence creating a suction. As this suction builds, fluid is pulled hrough the inlet, through the various valve chamber check valves to the outlet he volume of flow is determined by several factors including: the number and size of the pump chambers,cam offset, operating pressure, fluid viscosity.
- Q: Fire hydrant pump button, under what circumstances do not need to install?
- The installation of hydrant pump buttons depends on the type of water supply:(1) municipal water supply; (in this case, do not have to install)(2) there is a fire pump; (must be installed)
- Q: How many millimeters is the diameter of the water outlet of the four inch pump?
- This question is of no practical significance. The user does not care about this figure. The concern should be the nominal diameter, which is fitted with flanges and pipes. Moreover, the pump shell is cast iron, the inside diameter is not processed, and there is no matching parts, there is only one manufacturing size.
- Q: What is cavitation, centrifugal pump cavitation phenomenon how to solve?
- The pump is in operation, if the over-current part of the local area (usually the impeller blade inlet somewhere later) for some reason, the absolute pressure of pumping the liquid was reduced to liquid vapor pressure temperature, liquid vaporization began in the area, produce a lot of steam, forming bubbles, when the liquid contains a lot of bubbles forward by high pressure impeller zone, high pressure liquid around the bubbles in the bubble decreases drastically and rupture. Condensation in the bubble burst at the same time, the liquid particle filled hole at a high speed, this moment has a very strong effect of water hammer, and with a high impact frequency against the metal surface, the impact stress of hundreds to thousands of atmospheric pressure, impact frequency can be up to tens of thousands of times per second, serious breakdown when the wall thickness will be.The process of cavitation in a pump is caused by the bursting of bubbles and bubbles in the water pump and the destruction of the over-current components. Water pump cavitation, in addition to the over-current components will have a destructive effect, but also noise and vibration, and lead to the performance of the pump down, seriously when the pump will be interrupted liquid, can not work properly.
- Q: What are the basic technical parameters of the pump?
- Two, pump head H head is the unit weight of the liquid pump pumping from the inlet of the pump (pump inlet flange) to the outlet of the pump (pump outlet flange) energy value. Effective energy is a Newtonian liquid through the pump unit is obtained. The N m/N=m, the height of liquid column pumping liquid. Habits referred to as meters. Three, the pump speed is n RPM pump unit time revolutions, represented by the symbol n, the unit is r/min. four, the pump NPSH NPSH NPSH is also called net positive suction head, said main parameters of cavitation performance. Cavitation has been used a h power of five, the power of the pump. And the efficiency of the pump is usually refers to the input power, which is the prime mover on the pump shaft power, it is also known as the shaft power, denoted by P;
- Q: How is the pump level of submersible sewage pump determined?
- Generally as:The bottom elevation of sump sump plus 300 is the water level of pump stopThe top 300 of the sump top elevation is the pump water level
- Q: How high can the pneumatic diaphragm pump be?
- Pump made of polyvinylidene fluoride (PVDF) material two, the series of pneumatic diaphragm pump belongs to the fluorine plastic pneumatic diaphragm pump is also known as the corrosion products of pneumatic diaphragm pump, diaphragm liquid contact using PTFE material, using PVDF material produced by pneumatic diaphragm pump is mainly used in corrosive the pH, mainly used for chemical liquid conveying multiple solvent, corrosion resistance effect is very good. The series of fluorine plastic pneumatic diaphragm pump in high temperature less than 93.3 degrees.POM pump material also has good resistance to solvent and abrasion resistance, low friction resistance, moisture absorption is also low, the highest temperature of such pumps within 65.5 degreesPolytetrafluoroethylene (PTFE) membrane corrosion resistance is very good, in addition to liquid metal lithium, potassium fluoride, sodium fluoride, three chlorine, three fluoride high temperature oxygen, high flow rate, almost all of the chemical liquid transport (including concentrated nitric acid and aqua regia), PTFE material the maximum temperature to 176.6 degrees. However, for the diaphragm pump product as the diaphragm moves back and forth in work, we suggest that at a temperature of 120 degrees, the prerequisite is the pump body pump must be made of metal material and plastic material. The pump is the pump of PVDF material temperature is highest in less than 93.3 degrees.
- Q: How many concrete pump tube diameter
- The pump is generally divided into 125 and 150 two, the inner diameter is 125mm and 150mm. And the two kinds of each have high and low pressure points. Low pressure type type 125 pump for the pipeline diameter is phi 133,
- Q: What do you mean by the self coupling device on the pump?
- Auto is an installation of the pump, which comprises a pedestal, self coupling frame, a guide rod and a guide rod support, the bottom fixed coupling frame, vertical installation of two guide rods can easily be brought down without installing the pump, the pump at the bottom of the pool, the outlet of the pump and the discharge tube can automatically lock, don't need to bolt connection, automatic coupling position, so as to achieve the effect of simple and convenient. When you need to repair, pump the pump up without jumping into the sink.
- Q: 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.
- Q: Why adjust the centrifugal pump outlet valve can adjust the flow? What are the advantages and disadvantages of this method? Is there any other way to regulate the flow of the pump?
- This method can be used to regulate flow. The advantage is that it is simple and easy to use and the disadvantage is that the throttle consumes energy
