Product introduction:
QD/Q series submersible pump consists of pump, mechanical seal and motor. Pump is at the bottom part of pump,which is adopted centrifugal impeller.Motor which is monophase or triphase is at the upper part of pump and seal is used where pump and motor combine, which is a kind of double end mechanicalseal,"0" rings are applied to all static joints.
Application:
The motor pump is adopted multistage impellers, and has advantage of high head, which is widely used in countryside and industry for elevating water from well, irrigation, sprinkling and tower water supply, and also used in draining off water for building sites.
Work Conditions:
The pump can work properly and continuously under following op¬erational conditions:
1.Medium is not corrosive. Sand contents should be max.0.10% by volume and granular size should be max.0.20mm.
2.Medium temperature shouldn’t be over 40℃ and PH should be
6.5-8.5.
3.The pump should be operated within rated head. The pump should be min.0.5m over the water bottom and not be inserted into sludge.
4.Power frequency should be 50Hz,single phase voltage 220V ， three-phase voltage 380V,and voltage fluctuation should be 0.9-1.1 times than the rated.
- Q: How can the submersible pump level meter be connected?
- Install liquid level controller, two position liquid level sensor, controller to buy manual, wiring according to wiring diagram.
- Q: How does the centrifugal pump pump and cut the pump?
- Turn on the motor, observe the motor current, turn from high to low, observe the pump outlet pressure, and the pressure rise;Slowly open the outlet valve, so that the pressure drop slowly, the current slowly rising to the stable, the outlet valve to the maximum;Check the pump operation, stuffing box leakage, current, whether or not the rated current, motor, bearing temperature is normal, whether or not abnormal sound.
- Q: What are the reasons for sealing damage of centrifugal pumps?
- The reasons for sealing damage of centrifugal pumps are as follows: six, the specific contents and handling methods are as follows:First, the centrifugal pump water quality is poor, containing particles.As a result of poor water quality, containing small particles and medium hydrochloride content is high, forming abrasive wear, centrifugal pump seal plane or pull the surface, resulting in groove, ring groove and so on.Treatment method: improve water pressure or medium, replace machine seal.
- Q: Double floor sewage pump circuit diagram of a small problem
- Q 2, SA and SS are select switches, and different positions indicate the same difference between the two nodes. SA hits the left position 13, 14 to connect, hits to the right position 21, 22 to connect. SS hit the middle position, 5 and 6 turn on, 7 and 8 turn on; hit the right position; 1 and 2 turn on; 11 and 12 turn on; hit the left seat; 9 and 10 turn on; 3, 4 turn on.
- Q: What are the starting and stopping procedures for centrifugal pumps?
- The use of centrifugal pump can be divided into three steps, namely, start, run, stop.Start: you should do the following preparation before starting:(1) check the water pump equipment in good condition.(2) the bearings are filled with oil, the oil level is normal, and the oil quality is qualified(3) all the inlet valves of the centrifugal pump are opened.(4) pump water injection or vacuum pump diversion (except for flow), open the vent valve exhaust.(5) check the leakage of shaft seal. It is advisable to fill the seal with a little drop of water.(6) the motor rotates in the right direction.
- Q: Why can't the inlet of centrifugal pump be negative pressure?
- Can be negative pressure ah, the negative pressure here refers to the pressure is less than the atmospheric pressure, but the pressure can not be too low, to prevent water vapor below the saturated vapor pressure, so that water vaporization, cavitation phenomenon, the centrifugal pump will be considered.
- Q: I live on the 8 floor. Often there is no water. Life is very inconvenient. What kind of pump do I have to install? What should I pay attention to when I buy it? What's the pump for that brand? Should it be installed in that position?
- (4) before installation, make sure all pipes connected with the pump should be clean, and no solid foreign bodies which may cause damage to the pump shall be allowed.(5) apply the blind flange or other things to the suction, exhaust or open pump to ensure that no sundries enter the pump cavity during the installation.(6) check whether the pump random data is complete and complete; whether the pump surface has obvious damage. Only with complete data, no obvious damage to the pump, you can continue to install.(7) the installation of centrifugal pump with the coupling of the hand when turning slowly rotating coupling or pulley, observe the pump rotation are stable, flexible and adjustable, the rotor parts have no jamming, the pump has no debris crash, bearing the operation is normal, with elastic suitability.
- Q: If the calculation of the required pump flow is 45, lift 110, and the actual pump flow 100, head 125, what will happen in operation? Can I use it properly?
- Centrifugal pumps are too big to measure.There is a reason why the centrifugal pump does not measure up:The pump inlet pipe blockage, leakage.The pump inlet pressure is too low.
- Q: Centrifugal pump flow, why can be adjusted through the outlet valve? Can the flow of the reciprocating pump be adjusted in the same way?. Why
- Centrifugal pump, and is a very common method of centrifugal pump, flow with the head (or pressure) increases, off a small valve resistance increases, the pump head should be increased, then the flow decreased, whereas open valve flow increase
- Q: Why is the sewage pump device coupler?
- The automatic coupling device but the installation of GAK type submersible sewage pump, need lifting, people may not need to unscrew the screw water, the water pump can directly improve, after repairing down along the guide rail can realize sealing pump and pipeline, water pump and normal operation. Small sewage pump can be installed freely, large sewage pumps are generally equipped with automatic coupling device, automatic installation, installation and maintenance is very convenient.
