Q:About how to calculate the pump installation height?
Best to find water pump manufacturers, their own bad count. Sometimes is not necessarily correct, which is related to some parameters of the pump itself, with bad cavitation
Q:1.5KW water pump caliber is 40, what is the flow rate?
Because you provide a wide range of data, there are several models and lift and flow, if you are interested, please leave a message for me to communicate
Q:Explore the flow of water pump production process is like?
The main flow of water pump (take centrifugal pump as an example):Technical determination of Drawing > raw material storage > mold preparation > casting moulding > machining > parts experiment > Assembly > performance experiment > painting packing > storage.Here are a few key steps:1) the technique determines the graphMainly the work of designers. Generally according to the parameters of the pump (flow, lift, cavitation, efficiency, etc.) to determine the specific speed of pumps, impeller form, impeller size, impeller material, pump body, pump shaft and so on. One of the most important thing is to draw the impeller woodenpatterns.2) die preparationThe mold is mainly composed of workers according to the water pump impeller woodenpatterns production model.3) casting moldingThe casting molding sand is made on the base of the mould.4) machiningWater pump parts processing, because it has hydraulic flow channel, in considering the positioning clamping standard, must find the correct flow channel of the correct position. Avoid assembly, resulting in water pressure chamber and impeller flow channel skew, dislocation, uneven gap, or even rub, affecting product quality. In order to ensure the accuracy of parts manufacturing, it is necessary to design the appropriate tooling, and reasonable arrangements for technological processes, control process factors.
Q:Water pump is not Sheung reason
The problem you are experiencing is stressThe above answer is only considered in the case of water absorptionJust imagine, two pumps are normal work, the same suction pipe, how can there be dissatisfaction with water or vacuum state?.According to my experience analysisYour system is three sets of parallel, lift and flow should be the same, if not the same, not in this discussion, the topic should be set up.Lift is the same, that is, in two or three units at the same time, the resulting system pressurization is the same, and water will increaseBut now your traffic is increasing at two units, but it will not increase at threeYou have selected pipeline system design, in the design of head flow under single condition is constant, if the increase in open water pump, the pressure is constant, increasing water content, according to the continuity equation Q = A X V, then the flow velocity in the tube will increase;But when the third pumps, 2Q becomes 3Q, normally velocity should be larger, but the Darcy formula shows that the velocity increases, extension resistance and local resistance will be increased, and the double square, so you can open third pumps for reasoning, when the resistance effect caused by the pipeline the increase of water flow in the pipeline can not be reused, the general formula of constant current, now the whole pipeline in turbulent stateThat is, third pumps to do the work in the water and pipe wall friction in the loss, and actually did not play a role in water supplyThe solution is to increase the flow rate by increasing the water supply pipeline
Q:Is the pump lift horizontal or vertical?
A vertical, vertical lift is one meter (see environment), usually 5~10 times the horizontal distance
Q:Should the no-load power of the pump be equal to the rated power?
Not equal to.1. Calculate the shaft power of centrifugal pump:Pa = HQ P /102 KWType H - pump rated lift, m;Q - rated flow of the pump, m3/s;P -- medium density, /m3 kg;Efficiency -- pump rated conditions (ETA = ETA ETA ETA m h V, m -- h -- mechanical efficiency, hydraulic efficiency,ETA V - volume efficiency);Pa - shaft power under rated working condition of pump, KW.2, determine the motor powerP=KPa/.Among them, P--- motors are equipped with powerShaft power under rated condition of Pa-- pumpETA - pump drive efficiency, general pump is using direct drive 1.K-- original motive power margin coefficient (shaft power less than 15KW, 1.25; 15 Pa > 55KW, 55KW > 1.15;, 1.1)
Q:The flow of the pump will be reduced, the speed will change, the power of the motor will change?
Water pump flow rate, speed will not change, the power of the motor will change in general.Different types of pumps have different flow power curves. Only the most common centrifugal pump is used as an example to illustrate the relationship between the flow rate and other pump parameters. The typical centrifugal pump flow power curve is shown in the P-qv curve (red line) shown below.Turn left and turn right |According to the flow power curve, it can be seen that with the increase of the flow rate, the power increases linearly, and the power decreases linearly with the decrease of flow rate.In fact, the pump shaft power P= P gQH/ (1000 K), including H: head, unit m, Q: flow unit m3/s, ETA: for the efficiency of the pump, general 0.7-0.85, P: shaft power, unit kW, K: matching coefficient, small power is 1.25, P: work is like a water medium density.Therefore, for a specified pump, the power is proportional to the flow theoretically. In fact, as the flow rate changes, the efficiency of the pump changes, so it can only be close to the positive proportion.Running water pump speed generally depends only on the pump, power (motor, diesel, etc.) speed, the flow of water generally can not affect its speed. But in the design of pumps, the flow is related to the speed, and other design parameters remain unchanged, the pump speed is high, the pump flow.
Q:How should the water pump breaker be selected?
If it is a single-phase motor, rated current is 75A; three is about 30A; the contactor should be 1.1-1.5 times the rated current of the motor protection type selection of circuit breaker, circuit breaker: RMM1-100/33002 or 50A motor comprehensive protector, the price is not expensive.The circuit breaker (English Name: circuit-breaker circuit, breaker) refers to the closing, carrying and breaking current conditions and normal circuit switch device, load and breaking current loop abnormal conditions within the stipulated time. The circuit breaker is divided into high voltage circuit breaker and low voltage circuit breaker according to its range of use. The demarcation line of high and low voltage is fuzzy. Generally, more than 3kV is called high-voltage equipment.The circuit breaker can be used to distribute electricity, not frequently start asynchronous motors, the protection of the power line and a motor, can automatically cut off the circuit when they occur serious overload or short circuit and under voltage fault combination, its function is equivalent to the fuse switch and less thermal relay etc.. Moreover, after breaking the fault current, there is no need to change the components. At present, it has been widely used.Distribution is an extremely important link in the generation, transportation and use of electricity. Distribution systems include transformers and various high and low voltage electrical equipment. Low-voltage circuit breakers are a wide range of electrical equipment.
Q:Domestic pump does not turn, but the motor is energized what is the problem?
The home pump does not turn, but the motor is energized:A: there are heard buzzing, but can not move and no death card. It is likely that the boot capacitor is broken and that the capacitor can be measured with a universal meter.Two: if the motor is sure to have electricity, check whether there is low voltage or broken phase (three-phase motor). These conditions also cause the motor not to rotate, or the speed is low (easy to block), so it should be measured with a universal meter.Three: you can smell there is no burning flavor, may be motor winding interphase short-circuit. Bearings should be hard to break, and it's probably not good to find repairs.If the capacitor is replaced, it is better to choose the same capacitor as the original configuration parameter. If the capacitor is damaged and does not know or can not see the mark parameter, it can be calculated and matched according to the following formula:In C=8JS (F), the capacitance of the C- is S- (F). The current density of the starting winding of J- motor is generally selected from 5 to 7A/ (mm) 2, and the cross section area (mm2) of the starting winding winding. Generally, you can choose 1000W/40 F.
Q:(flood control emergency plan) what type of water pump should be used for flood control? How to choose
Do not know where to use, in case the the Yellow River burst, you might as well buy a boat
