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: What is a water pump coupling device?
The water pump coupling device comprises a coupler, a coupling flange, a guide rod and an upper fixing plate, wherein the contact surface of the coupling base and the coupling slide plate is provided with an annular groove, and a soft sealing gasket is tightly fixed on the groove. By adopting the structure, the coupling contact surface of the coupling slide plate and the coupling base is sealed firmly by an annular sealing groove
Q: Why should the pump be closed when the centrifugal pump is started?
Centrifugal pump has an important characteristic: when the pressure (head) is very low, the flow will be great, which can be seen from the characteristics of the pump curve. While the pump power is directly proportional to the flow rate, pump start, no pressure in the pipeline, caused by the pump flow, high power pump, and the pump motor, the rotating part from rest to high-speed operation, need a lot of acceleration, it will cause a great starting current
Q: Troubleshooting of diaphragm pump
In the application of the pump, these conditions are likely to encounter. Each situation can be divided into several possible reasons. This guide lists the causes of failures and gives appropriate corrective maintenance measures. The meaning of all the specific terms in the guide is listed later.Air valves - copper or stainless steel valves are bolted to the center of the pump by four bolts.The piston aluminum cylinder is enclosed in the air valve to control the gas flow.Cavitation - because the pump inlet for the amount of fluid to reduce or lack, the pump discharge is less than the amount of quantitative. In fact, the fluid chamber is full of fluid before it is discharged.Static pressure drop - the inlet pressure from the pump centerline to the free point - the inlet is measured in pounds, including the specific gravity and velocity of the fluid.
Q: Variable flow pumps are variable pumps
Yes. The variable pump is designed to change the flow rate
Q: The difference between diaphragm pumps, vacuum pumps and centrifugal pumps
The function of vacuum pump is to make vacuum, which has many kinds of structure, such as centrifugal, diaphragm (diaphragm), piston, liquid ring, rotary plate, jet type...................
Q: How to distinguish the flow and displacement in the hydraulic pump? What's the difference between the two?
For example, once you sprinkle water from the tank to the ground, one shot of water is 1000 milliliters, which is equivalent to displacement, once (pump turn) 1000 ml.,
Q: What is the displacement of the pump? Flow? What is the volume efficiency and mechanical efficiency of the pump?
Mechanical efficiency: the ratio of theoretical torque to actual torque of the pump.
Q: What is the difference between centrifugal pump and rotary vane pump? What are the distinctive characteristics or principles of rotary and centrifugal? O (a _ U) O thank you!
Directly said vane pump on the line, generally do not say rotary vane pump.The centrifugal pump is divided according to the direction of the liquid flow in the impeller
Q: Is vane pump good or gear pump good?
1) the reversible design of gear pumps can also usually reverse, but reverse after the suction port change, and the pump safety valve does not work; leaf pump is generally not allowed to reverse. 3) the single acting vane pump can be designed to change the eccentric distance by moving the stator at the constant speed, so as to achieve the purpose of variable direction.
Q: Types and differences of pumps
Classification and working principle of pump by structureClassification of pumpsInvolved pump standard product types are also very much, a centrifugal pump, metering pump, screw pump, reciprocating pump, hydraulic pump, submersible pump, oil pump, water pump, pressure test pump, vortex pump, cryogenic pump, vacuum pump, roots pump, molecular pump, gear pump, mud pump, corrosion-resistant pump deep well pump, water pump, mixed flow pump, axial flow pump, boiler feedwater pump, liquid pump, injection pump, chemical pump, pump plugging and no leakage pump, plastic pump, fire pump and so on, there are many. Its name is divided according to some conventional classification methods such as pump vane pump volume, pump etc., some are divided by purpose such as sewage pump, pump and other health, some names are more random as diffusion pump, liquid nitrogen pump. As long as the production of this product, with standard requirements, through a certain application and approval procedures may produce a new The standard, but sometimes the content also has a repeated cross, quite. The domestic and foreign standards, the domestic standard is more than the number of foreign standards. In general, such as centrifugal pumps are widely used, the production history of the pump more standard (total standard centrifugal pump up to more than 100). As new standard pump leakage pump this rapid development is relatively small. This paper introduces the structure and working principle of the pump according to the classification of the
