Pump and fan are a kind of conveying fluid power machinery, but the fan is used to transport gas, pump used to transport liquid, there is no difference between the two. Therefore, the energy saving measures applied to the fan can also be used for the pump

When the working surface water inflow exceeds the capacity of the submersible pump, the sewage pump and the ordinary horizontal pump relay must be used in order to reduce the number of the movement of the horizontal pump, jet pump becomes an ideal interme

The parallel pump all equipped with stepless speed regulating device (such as frequency governor) formed by the pump group, although the cost of a large investment, but the actual use of the effect and energy saving effect. Hours of load change, and speed

The parallel pump all equipped with stepless speed regulating device (such as frequency governor) formed by the pump group, although the cost of a large investment, but the actual use of the effect and energy saving effect. Hours of load change, and speed

Unable to control the parallel pumps, using input using the number of pumps in combination with fan coil system of changes in water availability. Because it is used to stop units to regulate the flow, so the regulation of echelon rarely, ladder asked grea

From the point of view of economic efficiency, the amount of water supply to a fan coil system is best suited to the number of fan coil units which actually turn on. So when the fan coil system is running under partial load condition, the pump (Group) can

Water pump noise on the vocal parts, mainly for the pump body noise, motor noise and pipeline noise 3 parts.

Because the suction pump is to rely on the pressure of the air into the water pump, so the water pump at the entrance of the pressure below the atmospheric pressure. However, the inlet pressure of the pump can not be less than the saturation vapor pressur

Because the suction pump is to rely on the pressure of the air into the water pump, so the water pump at the entrance of the pressure below the atmospheric pressure. However, the inlet pressure of the pump can not be less than the saturation vapor pressur

QJ series submersible electric pump, submersible three-phase asynchronous motor and pump two parts. Motor and the upper part of the pump body straight league the upper end of the motor shaft with reliable seal device, can effectively prevent the exchange

Stable operation: absolute concentricity of pump shaft and impeller excellent static and dynamic balance, to ensure the smooth operation, no vibration.
Leak: not the same material of hard alloy sealing, to ensure that the different medium transportation

Brushless DC pump: pump, coil and commutator rotation, magnetic steel and a carbon brush does not turn, direction of the coil current replacement change is with the rotation of the electric motor commutator and brush to complete, as long as the rotation

Mud pump performance of the two main parameters for displacement and pressure.

1. Can transport high concentration and high viscosity <10000PaS and containing particles of suspended slurry.
2. Conveying fluid flow stability, no flow, pulsation and mixing, shear slurry phenomenon.

1. Sewage capability, no plug, can be useful by solid particle diameter 30 ~ 80 mm.
2. The tearing mechanism can be a fibrous material tear, cut off, and then smooth discharge, no need to add a filter on the pump.

Centrifugal is actually a manifestation of the inertia of a body. Such as the umbrella drop, when the slow rotation of the umbrella, the droplets can follow an umbrella rotation. This is because the umbrella with water droplets on friction force is to dro

1. Stable operation: certainly the concentricity of the pump shaft and the impeller with excellent static and dynamic balance, to ensure the smooth operation, no vibration.
2. The is not the same material, hard alloy sealing, to ensure that the differen

Type ISW horizontal centrifugal pump, for the transport of water and physical and chemical properties similar to water and other liquids for in industrial and urban to drainage, high-rise building pressurization water supply, garden sprinkler, fire booste

The axial flow pump impeller is provided with 2 to 7 blades which are rotated in the casing of the circular tube. The upper part of the impeller pump casing is provided with a fixed guide vane, which is used to eliminate the rotational motion of the liqui

The mutual change relation and mutual restriction between the functional parameters of water pump: firstly, the top speed of the pump is the precondition of the top speed of the pump.
Pump function curve is mainly three curves: flow - lift curve, flow -

The basic structure of vertical pipeline centrifugal pump consists of six parts, namely, impeller, pump body, pump shaft, bearing, seal ring, stuffing box, and so on.

1. Suction pressure is less than or equal to 1.0 MPa, or pump system maximum operating pressure equal to or lower than 1.6Mpa, the pump suction inlet pressure and pump head is less than or equal to 1.6Mpa, pump hydrostatic test pressure of 2.5MPa, when o

1. Compact, small size, beautiful appearance, the vertical structure of the device is small, its center of gravity coincides with the center of the pump, thus enhancing the stability of the pump and the service life of the pump.
2. The fire pump suctio

1. Connecting body is connected by adopting a vertical structure, installation and debugging convenient, joint planning of motor and pump body, high concentricity, machining accuracy high, covers an area of greatly reduced, to reduce the pumping station c

Pump noise basically contains: caused by pump operation, the noise of the pump running caused by pipeline resonant noise, pump operation flow movement and the rattle noise.
