The self-priming pump suction and discharge head

self-priming pump suction and the relationship between the head and the relationship between the suction and discharge of self-priming pump, self-priming pump lift the relationship between the

a, what's a self-priming pump suction, all kinds of self-priming pump suction is how many meters

self-priming pump suction is refers to the self-priming pump imported low level to the self-priming pump is a vertical height of self-priming pump suction, the wastage of the horizontal distance need quantity according to the size of the pipe, elbow, coupled with self-priming pump flow rate calculated and loss.

self-priming height 3 - 4 meters of self-priming pump are: FPZ plastic corrosion self-priming pump, modern self-priming magnetic pump without leakage, ZXB fluorine plastic corrosion resistant self-priming pump, SFBX small stainless steel self-priming pump.

self-priming height 4 - 5 meters of self-priming pump are:

ZW self-priming sewage pump, ZX self-priming centrifugal pump, the WFB no seal self-control self-priming pump, BYQYZ gas-liquid mixing self-priming pump.

self-priming height 6 - 8 meters of self-priming pump are:

BYZK bibulous fast high self-priming pump suction, self-priming pump, with high viscosity BYNMZ BYZKW can completely clean water water pump self-priming pump.

self-priming height 8 - 9 m self-priming pump are:

BYXZXW large flow high vacuum auxiliary self-priming pump suction, BYQGZW belt cutting self-priming pump, high JGZKN mud self-priming pump suction

BYCYZXW diesel engine vacuum auxiliary self-priming pump

2, the relationship between the self-priming pump and suction head

self-priming pump head is actually and the inside of the data, such as the self-priming pump suction lift annotation is 15 m additional loss suction off 3 meters in practical use, you need to use lift 15 m - 3 meters results suction is actually the self-priming pump to lift in use, and overall loss is larger then the self-priming pump suction decreases in the lift of many users and manufacturers sales staff all don't understand this principle, when selecting so HuLv off the important details, such as: the need of head loss for 15 m working conditions on site, self-priming pump suction need 4 meters, then when choosing self-priming pump lift according to the 15 m to choose, this kind of situation in buying installed self-priming pump put into use will appear in the self-priming pump head amounted to less than 15 meters, many users will be considered a self-priming pump lift can not reach, is actually a self-priming pump suction loss dropped self-priming pump lift, so when choosing self-priming pump model should be counted the self-priming pump suction, it is also a self-priming pump sales staff necessary professional knowledge, if you know the need of self-priming height and head, in the selection should take both data and the data is the self-priming pump head should be chosen.

3, the relationship between the self-priming pump and suction flow rate

actually self-priming pump suction and discharge relationship and the relationship between the self-priming pump and suction head is roughly same, the higher the use of self-priming pump suction corresponding self-priming pump flow can be smaller, for example, some high self-priming pump suction of self-priming height can reach the level 9 meters or distance can reach more than 150 meters, this type of self-priming pump in self-priming height is higher and the horizontal distance under the condition of flow is far will have certain loss is likely to meet the traffic data of model parameter annotation inside, if the pipe is longer than we need according to the size of the pipe material, pipe combination need self-priming pump flow to calculate the corresponding self-priming pump suction loss.

4, the relationship between flow self-priming pump lift

the relationship between the self-priming pump head is closely linked, in the process of using low lift self-priming pump flow will become bigger, so a lot of users reflect a self-priming pump motor overload current phenomenon, can through the relationship between self-priming pump outlet valve control self-priming pump flow so that they don't super flow can control the current. If use the head is higher than the rated head of corresponding self-priming pump flow will reduce.

also need to know about transfer of liquid temperature is higher also self-priming pump suction and the discharge self-priming pump head, use high temperature self-priming pump need to understand how you can refer to: high temperature resistant self-priming pump

self-priming pump calibration of flow and head, and suction were based on the measured data of water and if the suction medium viscosity and larger proportion is heavier than water so all data have change, pumping mud like media suggested use: self-priming mud pump
