Product Description:

Production Introduction:
This model of pump is vastly used for aquariums, mine enterprises, gardens, family spray and irrigation, watering flowerand flush. It is characterized with compact sizes, light weight and convenient use. The float switch can automatically control on and off without people’s supervision. It is also equipped with 1-phase capacitance-operation asynchronism motor.or 3-phase asynchronism motor, the protector in which can automatically cut off the power when it overheat or overcurrent, thus guarantee the security and reliability of pump’s operation even in the atrocious environment.

Function and feature:
Model QDX(P) Stainless steel casing submersible pump is vastly used for aquariums, mine enterprises, gardens, family spray and irrigation, watering flower and flush. It is characterized with compact sizes, light weight and conbenient use. The float switch can automatically control on and off with the chage of water level. It is also equipped with 1-phase capacitance-operation asynchronism motor, or 3-phase asynchronism motor, the protector in which can automatically cut off the power when it overheated or overcurrented, thus guarantee the security and reliability of pump’s operation even in the atrocious environment.

Condition of usage:
1.The depth of the electrical pump below the water is no more than 5m;
2.The temperature of the water is no higher of 40*C ;
3.The PH figure of the water is between 6.5-8.5;
4.The grain diameter of the solids in the water is no bigger than 0.2mm;

Q:What are the reasons for sealing damage of centrifugal pumps?
Two, cavitation. Cavitation (mainly from a thermal centrifugal pump).Because the medium is hot water, the water temperature is too high to produce steam, the gas in the pipeline enters the pump cavity height, and the part of the gas can not be discharged, thus causing water shortage to run, the machine seal dry grinding is invalid, and the cavitation erosion device is not available.Process: replace the machine seal.
Q:Filter backwash pump for what use, what is the principle of work ah?
When the filter is in normal operation, the impurity will be trapped in the upstream of the filter (filter medium). As the accumulation of impurities, the filter media will be blocked, and the direct performance is that the circulation will decrease. Usually, when the flow drops to a set point (the industry is usually judged by the pressure drop),
Q:The water tank of the fish tank does not air out and only has the water outlet
The picture above is very clear, but I didn't say anything about it. My problem is solved. The intake pipe and the exhaust pipe are connected by the inverted T type. The intake pipe is upward, but not fixed. It can be rotated. The intake pipe can be rotated to adjust the number of bubbles
Q:What is a feed pump?
Feeding the role of the pump is to make the injection pump inlet pressure, increase the injection pump inlet pipe flow rate, in order to ensure high pressure water injection pump has sufficient supply.
Q:Why does the centrifugal pump start with a closed valve and the axial pump starts with an opening valve?
Because the characteristic curves of the two are different.The power of centrifugal pump decreases with the decrease of flow rate. When the flow rate is zero, the power is minimum, so the centrifugal pump is started with a closed valve.
Q:What is the main difference between SK water ring vacuum pump and 2BV water ring vacuum pump?
SK vacuum pump is a single-stage water ring vacuum pump, vacuum pump and motor separation, coupled with couplings, vacuum relatively low.
Q:Excuse me, what is the water pump from the lotus root?
Submersible sewage pump with septic tank, outlet pipe automatic coupling installation, dipping down can be.
Q:Centrifugal pump flow, why can be adjusted through the outlet valve?
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:What's the difference between a concrete pump and a concrete pump truck?
Concrete conveyor pump height and distance can reach hundreds of meters, which is far more than pumping vehicles, but it needs cloth tube, not flexible enough. Less investment.Pump car use more flexible, higher investment.
Q:Why should I pump the pump before starting the centrifugal pump?
Before the operation of the centrifugal pump, the pump must be filled with water, exhaust the air, before you start the operation. All centrifugal pumps should be handled this way, which is the centrifugal pump itself.The way of water diversion:1., in the centrifugal pump outlet increase water diversion pump (usually using vacuum pump), start the centrifugal pump before, start the vacuum pump, the centrifugal pump air into;2. increase the vacuum water tank before the intake of the centrifugal pump to meet the working conditions of the centrifugal pump;3. in the centrifugal pump inlet water increase valve, to meet the working conditions of centrifugal pump;4., if the water tank or water tank volume of water level is higher than the centrifugal pump position, the first operation of the front row empty, usually do not empty, you can use.
