DC variable speed PUMPwith Potentiometer Speed adjusting and PWM(50-800HZ/Amlitude 5V) or VR(0-5V) Speed adjusting connection

DC variable speed PUMPwith Potentiometer Speed adjusting and PWM(50-800HZ/Amlitude 5V) or VR(0-5V) Speed adjusting connection   :

 

 Features:

 

1. Life: Expected life span is about 30000 hours.

2. Low noise: ≤40dB, far from 1meter distance.

3. Duty work: The pump can sustain heavy duty work for a whole day.   Continuous operation.

4. Working conditions: Applying to indoor and outdoor under temperature 40   degC.

5.Working temperature: Within 100 degC. can work in water and out of water.

6. Can work in water or out of water.

7. Reliable Performance: Works quietly; Energy saving; High efficiency; Environment protection; We can offer over voltage protection, overheat protection, run dry protection, over current protection, idling protection, blocking protection, jammed protection signal feedback, speed control, ect.

NOTE :3phase dc is completely different with 3phase AC; 3phase DC means 3 pairs of magnetic polarity & sensor-less, power supply the same with common DC pump(two wires: positive and negative). Intelligent program-driving, sensor-less,PCB board outside (main factor that pump can be high-temperature resistant)

Q:What are the new regulations in the design of main and auxiliary water bin and water pump room in coal mine?
The main water bin must have a main bin and an auxiliary warehouse. When a sump is cleaned, another water tank can be used normally.When the normal water inflow is below 1000m3/h, the effective capacity of the main water tank should be able to accommodate the normal discharge of 8h.The effective capacity of the main water bin can be calculated by pressing type in the mine where the normal water inflow is greater than 1000m3/h:V = 2 (Q+3000)Effective capacity of V-- main water bin in type m3;Q-- mine hourly normal water inflow, m3.However, the total effective capacity of the main water storage tanks shall not be less than the normal water inflow of 4h.The effective capacity of the water tank in the mining area shall be able to accommodate the normal water inflow in the 4H mining area.There is a big difference between the maximum water inflow and the normal water inflow in the mine. The drainage capacity and the water storage capacity should be specially designed.The water inlet chamber should be set up. A sedimentation tank shall be provided for the filling of water sand, hydraulic coal mining and other gushing water with a large amount of impurities. The water storage capacity of short positions must often remain above 50% of total capacity.
Q:Water pump 50HZ impeller and 60HZ what is different, why not the same?
60Hz pump and 50Hz pump itself is not much difference, just that the motor speed, the rated speed is 3600 rpm, 1200 rpm, 1800 rpm, the latter is generally 3000, 1500, 1000 etc.. If it is to use the same pump, the difference is that the 60Hz motor pump flow is 50Hz, motor water pump flow of 1.2 times, the lift is 1.2*1.2=1.44 times, power is 1.2*1.2*1.2=1.728 times. So in the actual manufacture, especially some relatively large flow lift pumps, pump motor using 60Hz to use 50Hz thicker than the spindle motor of the pump impeller, the difference between the two, in addition to empty size shaft is different, what basically no difference. As for the data of package angle, the water conservancy models of different factories are different, but I don't know whether there is any difference between them. Most of them make no difference. However, if you want to use the 60Hz pump to achieve the same flow rate as the 50Hz pump, the impeller of the former should be cut to 0.833 times the size of the latter.
Q:Water pumps are always pumping water, what's the matter?
Is the self-priming pump, not the self-priming pump, the actual suction is too large?How much is the water pump voltage?Inlet pipe leak
Q:Why should the water pump be opened in time after the pump is started?
Just like peeing, just getting ready to pee, it feels like holding a chicken.
Q:What does diving pump 80JYWQ40-15-1600-4 stand for?
3, sewage pump flow per hour 40 square water head 15 meters, 1600 rpm, with power 4KW
Q:Pump adapter belongs to the system of fire pool equipment?
Does not belong to the fire pool system! Pump adapter is mainly used for fire engines through the adapter system pressure, outdoor fire hydrant fire with one hand, one hand is to provide water for the fire truck. According to the 10~15L/S calculation of each pump adapter
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:How many pumps does a 50 meter water head use?
Considering the pipe resistance and the water head, it is recommended to use the pump at 65 meters or so!
Q:Two pumps automatically switch start control circuit,
The puddle is full, the float switch is closed, and the relay J1 works to drive the first motor. The J1's work makes the intermediate relay 'J' work and locks itself, preparing for the work of the second machines. The water level is lowered to the required minimum position, the ball is broken, the motor is stopped and the motor is stopped. When the water level rose to the highest position again, the floating ball closed again, the relay J2 and self-locking relay J2 to drive second motors, instant intermediate relay are opened, when the water level again be reduced to the lowest position, float off, the motor stops working, stop by working in front of the intermediate relay. The whole circuit back to the original state. So that the two motors work alternately.It should be noted that the circuit diagram for simple to understand, only painted the control circuit, there is no main circuit, there is no missing phase, leakage, over-current and other protection, the actual installation needs to be installed. There is the role of time relay is to ensure that the relay J2 normal work, the intermediate relay is disconnected, so that the motor 2 does not occur wrong action, time relay can be set to a few seconds, or even less than a second. Intermediate relay can also be controlled by time relay, and its time is also set very small, so as to avoid J2 short time possible power supply.
Q:What is the difference between a sewage pump and a clean water pump? Why can't sewage be pumped with clean water?
The main difference between water pump and sewage pump is that:Impeller and runner design, as well as other parts of the configuration are very different.1., in order to prevent clogging of sewage pump, the main design of large flow channel, so naturally lead to relatively low efficiency, so the head is generally not high. Clear water pump flow smaller, smaller clearance, the head is relatively high.2. in order to prevent the wound, water pump impeller design is more simple but not ring pump, equipped with tips, cloth and other debris can be crushed after the pump, and the impeller water pump is relatively complex, but the efficiency will be significantly higher than the former.Why can't the sewage water pump and impeller: because features of key design, resulting in water pump for sewage situation is likely to occur, blocking, winding, wear and corrosion occurs, resulting in damage to pump or scrapped, so water pump can not be used for sewage.Sewage pump is a pump and motor conjoined, and at the same time submerged into the work of pump products, and general horizontal pump or vertical sewage pump compared to the sewage pump compact structure, small footprint.The water pump is for the transport of water and physical and chemical properties similar to water and other liquids used, suitable for the industry and the city water supply and drainage, water pressure high-rise buildings, garden sprinkler, fire booster, long-distance transportation, HVAC refrigeration cycle, irrigation, bathroom, cold and hot water circulation pressurization and equipment.
