DC electric diaphragm pump performance parameters in a number of technical terms specific meaning

There are many terms in the performance parameters of the DC electric diaphragm pump, if the one-sided understanding, it can be a big mistake, in order to prevent further occurrence of the error, the DC electric diaphragm pump performance parameters It is necessary to introduce some specific terms of the specific terms, the following talk about the specific meaning of some professional terms in the performance parameters of DC electric diaphragm pump. DC motor diaphragm performance parameters in a number of technical terms specific meaning 1: "maximum flow" refers to the pump outlet no resistance, no output pressure to overcome the resistance (ie, pump output pressure close to zero), the pump pumping rate (flow )to reach maximum. Once there is resistance, pump flow will decay, and the output pressure was a similar inverse relationship. 2: "suction stroke", also known as "maximum self-absorption height." That is, the maximum height at which the pump can automatically suck water (the vertical distance between the pump suction opening and the liquid to be sucked in) without adding water. Our pumps are self-priming pumps, the standard suction refers to this situation. Some centrifugal pumps do not have the ability to self-priming, the first use must add water Caixing. Although some diaphragm pumps also have the ability to self-absorption, but the subject of "Suction" often with the "inlet all the air" can draw water vertical height difference, this point please note. 3: "maximum lift" is also called "maximum drainage height". Refers to the pump outlet connected to a sufficient length of the water pipe, the water pipe lifted vertically, the pump can use the output pressure to hit the maximum vertical distance from the water outlet height. Excluding suction stroke. If the pump outlet nozzle is not connected to the tube, or even if the tube is connected to the level, or not installed resistance devices (such as valves, nozzles and the like), the pump output pressure is very small, the pump flow to achieve maximum. In use, 0 <actual pump lift <maximum lift, not a pump work, the lift to reach maximum, but depends on the load. For example, you can use the degree of valve closure to control the actual level of head. 4: "maximum output pressure" is also called "maximum shutdown pressure". Pump operation, the drainage end by the resistance or a large load, it will show the output pressure to overcome this resistance, when the pressure to a certain extent, in order to avoid excessive pressure caused by pump internal components damage, random pressure protection The switch will start, stopping the pump. The pressure at this time is called the pump's "maximum output pressure." The pump restarts only when the resistance or pressure at the drain end is less than the "maximum output pressure". The above is the DC motor diaphragm performance parameters commonly used in the specific meaning of some of the terms, I believe with these introduction, you maximum flow, suction stroke, maximum lift, the maximum output pressure have a deeper understanding and understanding.
