3,product introduction

WQD WQ type submersible sewage  pump/dirty water pump consists of pump,mechanical seal and motor.Pump is at the bottom part of motor pump,which adopt centifugal impeller. Motor is at the upper part of motor pump and is a single-phase asynchronous motor or three-phase motor.Mechanicalk seal is between pump and motor,and it'sa kind of double end mechanical seal."o"rings are applied to all static joints of the submersible pump.Inner-installed protector prevents the pujmp from damages due to abnormal power,colg and overload etc.


4, working Condition

1.Transport liquid water temperature is less than +40°C

2.The PH value of the media is between 6.5to 8.5

3.The volume per centage of impurity in the medium is less than 0.1%,grain smaller than 0.2mm

4.Pump should be rated near lift the appropriate range,submersible pump head can not be too low,below the stiplated 80%of head easily lead to thermal protector,so that pumps stopped running,and even cause electrical damage.

5.Diving depth of no more than 5m.

Q:How about the depreciation of vacuum pumps?
(five) electronic equipment, for 3 years.The depreciation period of a vacuum pump can be calculated for 5 years. The expected residual rate is generally 5%, or it can be estimated by itself.
Q:Do you have a suction pump higher than 9 meters?
This screw self-priming pump suction process can be more than ten meters or more, my family is using this
Q:What is the cause of the damage of pump bearings?
First of all, know your pump model, and what is the bad bearing, in order to accurately judge for you. Because in addition to some common reasons, the structure of different pumps, bearing damage caused by the reasons are different. Otherwise it is fraught with itching shoes.
Q:Why is the submersible pump tripped on an electrical switch?
Submersible pump cable or motor insulation is damaged.3) motor water solution
Q:Bolus dosage of infusion pumpWhat is the purpose of the pill dose control in the special safety standard for infusion pumps? If the risk is not properly controlled, what is the degree of risk? And how can the open infusion pump be used in this regard?
(1) the pellet dose in the safety standard of the infusion pump refers to the amount of liquid that is transported to the patient in a short period of time(two) pill dose limit is mainly to control the risk of accidental pill dosage. Especially after the mandatory requirements of pipe blockage in the elastic pipe storage liquid limit amount of agglomeration and the limitation of these methods to release pill dose.
Q:Metering pumps related matters
1., exports higher than imports, avoid siphonage2. the pump head and the injection valve require vertical installation3., the attached pipe can be tightened by hand, please do not use the tool; the thread does not use the raw meal belt4. the supply voltage is stable and grounded5. installation environment clean, spacious, well ventilated) 1) metering pump suction is not normal
Q:How to select hydraulic pump?
2. displacement and flowDisplacement refers to the pump (or motor) every turn a week, by the size of the sealing chamber geometry variable discharge (or enter) the volume of liquid, commonly used unit is ml/r (ml / rev). Displacement can be changed as a variable pump (or variable motor), and the displacement can not be changed into a quantitative pump (or a quantitative motor).Actual flow is the amount of flow at the outlet (or inlet) when the pump (or motor) is operating. As the pump itself leaks, the actual flow is less than the theoretical flow. As the motor itself has an internal leakage, to achieve the specified speed, in order to compensate the leakage, the actual flow of input must be greater than the theoretical flow.
Q:What does "anti pump" mean in pump operation?
Function: anti pump effect when used for pumping concrete pumping occurs overpressure, the pumping pressure is above 25MPA, the concrete conveying pipe out of ash, can be understood as the precursor of pipe blockage, at this time should immediately use the anti pump, the concrete from the conveying pipe in the suction into the hopper, thus preventing plugging happen
Q:How to select the fire pump?
Modify the part: (the design of regional common fire pump should be in accordance with the requirements of the original design, building design) contains a 55m high building, and the basement is about 6m, the pump reached in the basement height about 61m (common fire pump should be based on the highest floor of other low floor area, low ring and take in this case, relief measures) 61 levels, the most unfavorable hydrant to reach 0.07MPa (maximum allowable 0.5MPa) plus loss of lift at least about 90m more appropriate, of course can be higher to take relief measures (120 too high), the basic flow of lossless (with the same time there is only one building fire) according to the maximum amount of a building fire water pump set can be, there must be a backup with a preparation, and then select the appropriate pump manufacturer specification query.(the 20 houses on 99m are only shared with a 135m pump)
Q:What is the function of the heating pump system for the water pump design?
As the feed water temperature is higher, before starting, if not enough to warm the pump, the pump body temperature is uneven, there is a hot, cool phenomenon. The upper part is inflated and the lower part is inflated"
