Structural Characteristics
XBD-I series horizontal single stage fire pump set is mainly made up of 1.pump cover 2.impeller 3.shaft 4.seal ring 5.packing ring 10.Suspension bearing parts 12 .etc.
Pump casing and pump cover of XBD-I series horizontal single stage pump are split from back of impeller,namely,back-open structure.It is convenient to maintain,when maintaining,pump casing,suction pipe,discharge pipe shall not be dismantled,so rotor parts can be taken out for maintenance easily.
Pump casing(namely,pump body and pump cover) composes pump working room.Impeller,shaft and rolling bearing are rotors of pump.Suspension bearing parts support the rotor parts,and rolling bearing bears the radial force and residual axial force of pump.
To balance the axial force of pump,there are seal rings on the front shroud and back shroud of impeller,and there is balancing hole on the impeller back shroud.Some of the pumps do not have too much axial force,so there are no seal ring or balancing hole on the impeller back shroud.
Pump seal is made up of packing gland 9,shaft sleeve 8 and packing 11,or mechanical seal is applied to avoid air getting inside or too much water leakage.
There is a shaft sleeve through the packing cavity to avoid shaft abrasion.There is o-ring between shaft sleeve and shaft to avoid the air getting inside or water leakage.
Driving way of pump is connected through coupling and motor.Pump rotates clockwise from the direction of drive.
- Q: Piston filling and peristaltic pump filling which precision is high?
- First of all, we should know the working principle of each, and analyze the accuracy from the principle, this problem is very important. Piston filling, such as the injection of drugs that we have been ill, the accuracy of the piston pump depends on the accuracy of the motor and the area of the unit cross section
- Q: Troubleshooting of diaphragm pump
- The ratio of flow to water weight at a specific weight of --68F. 68F water has a specific gravity of 1Static suction head - the vertical distance from the liquid level to the central line of the pump. The pump shall be above the level of the liquid.Vapor pressure the pressure of all the steam on the free surface of the liquid. In any pump operating system, the operating pressure shall not be lower than the vapor pressure, otherwise the steam will be partially or completely cut off into the pump fluid. Viscosity - because of the presence of friction in the fluid, the property of viscosity gives the fluid resistance to flow.Water hammer action -Water hammer is a sudden power failure, or in the valve closed too fast, due to pressure, flow of inertia, produce water shock waves, like hammer hammer, so called water hammer. The force produced by the flow of water shock waves can sometimes be very large, thereby damaging the valves and pumps. Water hammer effect refers to the inside of the water pipe, the pipe wall is smooth, flow freely. When the opening of the valve suddenly closes, the flow of water to the valve and the tube wall, mainly the valve, will produce a pressure. As the pipe wall is smooth, the subsequent water flow in the role of inertia, the fastest reach the maximum and damage, which is the water conservancy "water hammer effect", that is, "positive water hammer.". This factor should be taken into consideration in the construction of water conservancy pipelines. On the contrary, the valve closed in a sudden opening, it will produce water hammer, called negative water hammer, but also a certain destructive power, but not the former big.. Causes and treatment methods of common failures of diaphragm pumps:
- Q: What are the important parameters of the pump?
- Because the lift refers to the effective energy, pump output unit of heavy liquid obtained from the pump so that the product of head and the mass flow rate and acceleration of gravity, is the effective energy output from the pump in unit time of liquid -- effective power pump:Pe= P gQH (W) = QH (W)In the p - density of liquid pumping (kg/m3);Gamma - pump heavy liquid delivery (N/m3);Q - pump flow (m3/s);H - pump lift (m);G - gravitational acceleration (m/s2)The shaft power P and effective power Pe is the difference of power loss in the pump, the size of the pump efficiency to measure the efficiency of the pump. As the effective power and shaft power ratio, with ETA said.
- Q: Pump unloading in hydraulic transmission,
- Can be used for short-term shutdown, pump non-stopNo unloading, usually through the overflow valve back to the tank, high pressure, power, at this time insurable pressure, and so on
- Q: What is double hydraulic pump?
- Two hydraulic pumps installed on one shaft can be connected to increase output flow, and can also be connected to increase output pressure. See how the demand is. The system can change the mode of application at any time.
- Q: How many kinds of pumps are available and the operating principles of various pumps?
- There are many kinds of pumps. There are different classifications according to different standards. If classified according to the principle of work, can be broadly divided into the following four categories:1, vane pumps: centrifugal pumps, axial pumps, mixed flow pumps, vortex pumps, etc.;2, displacement pumps: piston pumps, piston pumps, diaphragm pumps and so on;3, power rotary pump: screw pump, gear pump, etc.;4 、 special function: jet pump, water hammer pump, magnetic drive pump, etc.;
- Q: Rules for operation of centrifugal pumps
- 3, start the pump, wait until the speed reaches the normal speed, slowly open the outlet valve, observe the ammeter at the same time, and control the current in the rated current range of the motor.4, the operation requires smooth operation of water pumps, no abnormal noise, no pressure fluctuations. The abnormal situation should be stopped in time.
- 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: Why does the centrifugal pump start and close first when the outlet valve is closed?
- The operation rules of centrifugal pump strictly required to close the outlet valve before the shutdown, boot and then slowly open the outlet valve, regulating pipeline pressure and current range. The reason is: the centrifugal pump in the startup process in order to avoid large starting current caused by electrical faults, such as circuit breaker tripping,
- Q: Pneumatic diaphragm pump compressed air pressure is 4 kg, the discharge pressure is how big?
- Have to know the ratio, pneumatic pump, if high pressure, you can have 2:1,3:1
