Product Description:

Product introduction:
QDX. QX 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 three phase is at the upper pa" of pump and seal is used where pump and motor combine, which is a kind of double end mechanical seal "O " rings are applied to all static joints. Floator switch can be equipped to control pump" starting and stopping automatically according to the water level.

Application:
This series pump is small and light, which is widely used in countryside for elevating water from well, irrigation, sprinkling and domestic water supply, and also used in draining off water for fishpond and building site.

Work Conditions:
The pump can work properly and continuouslyunder following operational conditions:
1 .Medium is not corrosive, Sand contents shouldbe max. 0.10% by volume and granular sizeshould be max.0.2mm.
2.Medium temperature shouldn’t be over 40℃ and PH should be6.5-8.5.
3.The pumps should be operated within rated head.
4.The pumps should be fully submerged into water with depth of less than 3m mad max. the pump should be min.0.5m over the water bottom and not be inserted into sludge.
5.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:What is the minimum continuous flow of a pump?
Quality solutionsMinimum flow of pump, minimum continuous flow of pumpIn order to ensure the proper use of the pump and the normal operation of the pump manufacturer will indicate the minimum pump in the sample of the continuous operation flow, the correct selection or use to warn or instruct users. According to the provisions of the API standard, the minimum continuous flow into the minimum continuous stable flow and continuous flow. Most small thermal limit(1) the minimum continuous stable flow.API standard specifies the minimum continuous stable flow refers to the vibration limit does not exceed the standard set by the pump can work normally. The minimum flow pump at small flow rate, there will be noise and vibration increase, API of this provision is to ensure that the service life of the pump, avoid due to improper operation of the pump caused by the adverse effects.
Q:Variable flow pumps are variable pumps
Yes. The variable pump is designed to change the flow rate
Q:Any center of the pump
For the first time, the pump and motor were placed on the base and not fastened (Cu Zhaozheng);Second times, the pump and motor have been tightened, the inlet and outlet flange bolts are not fastened;Third times, the pump runs 24 hours later.
Q:Why can't the centrifugal pump pump the vacuum?
Working principle (taking centrifugal pump as an example):Prerequisites, processes, and requirements for the overall system structure.
Q:Why is the submersible pump tripped on an electrical switch?
There should be the following reasons: 1) the setting value of the trip switch is too small, and the operating current of the submersible pump exceeds its setting value, and the switch is tripped
Q:What's the submersible pump?What is a submersible pump, and what about it?
Deep well submersible pump is a fountain, drinking water transportation, irrigation, hot springs, high-rise transport facilities, etc., deep well submersible pump excellent performance, so widely used in various fields.
Q:Does the control cabinet of the fire control pump need to be related to the fire control room?
Normal words are needed, but when you check and check, has anyone checked?
Q:Roots pump and dry pumpRecently, the work involved in the vacuum pump, do not understand this, is a ads602 vacuum pump
The front stage pump to a certain pressure to start the roots pump, roots pump has advantages of is at the entrance of low pressure gas pumping speed is high, popular point is in high vacuum pumping speed is still relatively large. With the former pump can achieve different limit the vacuum is different.
Q:What is the function of the heating pump system for the water pump design?
Will cause some of the internal friction gap disappeared, the coupling center damage. In this case, starting the pump inevitably results in vibration, friction, etc.
Q:How long does the fine stone pump need maintenance? What should I pay attention to?
Check the line from the relief valve to the cylinder inlet to ensure that there is no external drainage or deformation due to impact and wear and that the connections are complete and fully tightened. - replace any damaged pipe immediately. - change the original settings strictly: all adjustments and calibrations can only be done by professionals. - no fucks hydraulic components, otherwise manufacturers on product warranties and liability shall not be responsible for. A warning because the hydraulic oil can reach very high temperature, there is the danger of burns, so open pipe fittings should take appropriate protective measures. Any replacement parts must conform to the level specified by the manufacturer. 8.2 check lubrication grease pump in oil at any time to ensure adequate and clean the lubrication pipeline joints without overflow phenomenon. Check the lubrication of the running parts at any time, and find the parts which lack oil, and check them immediately to prevent accidents. - check that the centralized lubrication system is effective daily. When the grease pump is empty, the grease added is often not easy to pump out because of the bubble. In this case, open the outlet of the pump, run the grease pump until the grease is re flowing, and then connect the pipe
