Product overview

KAIQUAN ZQ/HQ type blade mode submersible axial flow pump, mixed-flow pump is a young generation of the axial flow pump, mixed-flow pump products, retained the single large flow, lift range wide, high efficiency, etc, also because of the motor and pump constitute an organic whole, run into the water, has the incomparable virtues than the conventional unit.

Application field

Urban water supply, water diversion project, city sewage drainage system, sewage treatment engineering, thermal power plant circulating water, the dock water supply and drainage, water diversion hub, drainage irrigation, aquaculture, etc.

Product features

1, can transport water, sewage, mild medium temperature can be up to 40 ℃, PH 4-10;

2, good water conservancy model, well-made, guarantee the performance of user requirements;

3, double mechanical seal, reliable to prevent leaking, large pump for large axial force, using special thrust bearing, reasonable structure design, lubrication, heat dissipation is good, the bearing service life is long;

4, motor with F class insulation, high temperature resistant, is equipped with temperature protection, monitoring and leakage alarm device;

5, can form a complete set of a controlled two to a control model of four electric control cabinet, which can realize the failure pump automatically shut down, the standby pump start automatically; Keep fault signal (self-diagnosis), and other functions, to ensure the high reliability of operation;

6, submerged pump and cooling condition is good, pump running balance, good stability, small vibration, low noise;

7, the user can according to the requirements, design of the underground pump station and improve environmental features;

Small 8 and pumping stations, civil engineering, construction of simple structure, greatly reduce the investment, can cut pumping station project cost 30% to 40%;

9, pump integration, saving time and labor for installation and maintenance, saving cost;

10, product series, water pump high efficient area wide, in line with the working condition of the user, high efficiency and energy saving, low operating cost;

11, convenient management, management, operation cost;

Q:How to adjust the flow of piston pump?: Changing the size of the current in the solenoid valve can change the angle of the tilting element, and then change the stroke length of the plunger in the pump cylinder, that is to say, to change the flow of the pump. An inclined angle is called a quantitative pump, and the angle of inclination can be changed, which is called a variable pump.

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:How does the centrifugal pump pump and cut the pump?: Can not be generalized, the pump is divided into many categories, centrifugal, reciprocating, screw type, diaphragm type, and so on, the starting steps of each pump is not the same. The following is the centrifugal pump and reciprocating pump to do a simple introduction. Check the items and so on.Centrifugal pump: first open the pump inlet valve, pump exhaust, and then start the motor, slowly open the outlet valve. If it is a high speed motor or multi-stage pump, open the motor before the outlet valve slightly open.Reciprocating pump: slightly open the inlet valve of the pump, fully open the outlet valve. After starting the motor, at the fully open inlet valve.Here is a brief introduction. I hope it works for you.

Q:What is the relationship between the minimum suction vacuum of a pump and the required cavitation?: When the pump is working, the liquid at the inlet of the impeller, due to a certain vacuum pressure will produce steam, the vaporization of the bubble in liquid particles under the impact of movement, the impeller and other metal surface erosion, thereby damaging the impeller and other metal

Q:How many pumps does the 80cm tank use?: Mainly look at the flow of the pump, all pumps have flow signs, such as 15L/HThe above is I at random, meaning that 15 litres per hour. You should calculate the volume of your cylinder, that is, the length of the tank, the width and the height of the water surface, the unit is cm. The result is 1000, which is the volume of your fish tank

Q:Types and differences of pumps: (I) volumetric typeClassification reciprocating rotary typeThe basic principle of reciprocating action by the piston in the cylinder in the cylinder volume changes again, with the suction and discharge of fluid in the shell or the rotor rotating member rotates, the volume of work between rotor and casing changes to the suction and discharge fluid, such as piston pump gear pump, screw pump(two) blade type;The main structure of vane pumps and fans is rotary, bladed impellers and stationary housings that rotate fluid through the impeller to do work, thereby enabling fluids to obtain energy

Q:If you use an ordinary 15W submersible pump, put it in the tank, if the leakage, the fish will hang it?: What will happen then? The aquarium glass is an insulator. The water in the fish tank has the same potential as the live wire, and the fish is like a bird standing on the fire line. No electricity flows through their bodies, so they won't get electrocuted. But if you put your hands into the water, you will get an electric shock, because the line voltage through the water, then your body and the earth to form a loop, current flowing through your body you will get (of course, if you stand on the insulator does not get an electric shock)

Q:What are the functions of a disposable infusion pump?: When the transfusion is too slow, the dosage may not be enough, or the infusion time is prolonged unnecessarily, the treatment is affected, and unnecessary burden is added to the patient and the nursing work. In routine clinical infusion, the infusion of hanging bottle is generally used, and the speed of infusion is controlled by the use of a manual clamp. The speed of infusion is not easy to be controlled accurately, and the workload is great.Treatment of cancer patients with chemotherapy and critically ill patients need to make drug infusion rates constant, by adjusting the input speed and duration of chemotherapy drugs is continuously injected into the uniform, not only to achieve the best effect of chemotherapy, and to minimize the side effects of chemotherapy drugs.People suffering from diabetes need to inject a certain amount of insulin at a certain speed. The previous approach is basically a large dose of insulin injection, which not only caused a huge waste, and the effect of time is relatively short, so for a conveying device of flow and velocity control, to carry a small amount of drugs and precisely control the conveying speed and flow.Some special drug delivery to the elderly, children and physical weak, such as drugs, antihypertensive drugs, sodium nitroprusside (three TPN codehydrogenase) when the infusion rate and dosage should seriously control accurately, otherwise it will have serious consequences.

Q:Filter backwash pump for what use, what is the principle of work ah?: Regeneration of the filter medium is required to regain the filtration capacity of the medium. The regeneration process is mainly accomplished by the backwashing pump (the backwash pump is not a special pump, referring to the pump for the completion of the process). The working principle is through the cleaning liquid from the downstream of the filter into the backwash pump (alkali, acid and water), reverse flushing filter medium, cleaning liquid discharged from the upstream, this process can be attached to the dielectric surface and internal impurities washed away.

Q:What is double hydraulic pump?: The 2 pumps are all coaxial connected together, driven by a motor, the general gear pump, piston pump
