1. Purpose:
Model HW pump is a horizontal single stage single suction volute mixed flow/axial flow pump and suitable for transporting pure water or the other liquid with both physical and chemical
natures similar to those of water, with the temperature of the liquid to be transported not over 50 , for the farm land irrigation, industrial and city water supply and drainage etc. multiple places.
The pump's performance range: flow 130~9000m3/h, head 3.5~22m.
2. Features:
Simple structure, reliable use, easy installation, high efficiency,small body, light weight.
3. Mode of actuation:
Direct and variable actuations. The common movers are motor and diesel engine. Please note the model (power, rotating speed) of the mover so as to make sure of the norms of the
clutch or the belt pulley.
4. Water pump rotation direction
Viewing from the pump inlet, the impeller rotates counterclockwise generally (clockwise with 650HW-5, -7, -10 pump).
5. Model meaning:
Take 300HW~8A as the example.
300----pump's inlet and outlet diameters.
HW----horizontal volute mixed flow pump.
8----designed head m.
A----cut the impeller's outer diameter or replace it with
an impeller of different performance
- Q: Know flow and lift how to calculate the pump power?
- P: the density of refrigerant, when the working fluid is water, P =1ETA - pump efficiency, can not find desirable value =0.8N=30x (200/3600) x9.81x1/0.8=20.44 = 20 (kW)(that is, 20kW motors)
- Q: Rotary vacuum pump does not meet the requirements of vacuum, what are the reasons?
- (1) the disk, stator or bushing is worn and shall be inspected, trimmed or replaced with a rotary vane vacuum pump.(2) the pump temperature is too high, which not only reduces the viscosity of the oil, increases the saturated vapor pressure, but also may cause cracking of the pump oil. Ventilation, cooling and environmental temperature should be improved. If the exhaust gas temperature is too high, should be cooled before entering the pump, the environment temperature is high, should try to use a better high speed vacuum pump oil or 3# diffusion pump oil. (10) because of the deformation, wear or movement of the parts, the maximum opening height of the check head can be reduced or even unable to be opened, the intake of oil is too little, and the vacuum degree of the rotary vane vacuum pump is reduced, and should be adjusted as shown in the assembly section. Open high, more oil, but open too high, check valve in some places on the stop, it will not automatically drop, lost to prevent oil returns. The commonly used rotary vane vacuum pumps mainly include double stage rotary vane vacuum pump and single-stage rotary vane vacuum pump
- Q: What is the name of the day pump and ground pump? Specific introduction
- PumpGround pumps are used very frequently in many large basements, because they have no boom, so they need to be taken over manually. In addition to the site, for those days to pump the high-rise buildings, such as 200 meters or 200 meters altitude, can also take over to transport concrete by pump, but the premise is to have enough power to pump concrete will hit above the height and the length of nozzle can reach the height of the floor.Thus, the day pump and ground pump have their respective advantages. The pump is easy to use, but the ground pump can make up for the height that the pump can not reach. At the same time, the price is relatively cheap, so users can choose the corresponding concrete pump when they are in use.
- Q: Pump unloading in hydraulic transmission,
- Unloading water, from the literal interpretation is along the pump, leakage of water seal through the head, the water with certain pressure (even with relief effect seal). The water as the working quality is asked to be recycled, now the design of some use it as a water seal, and others by direct recovery, but eventually recovered.
- Q: What are the starting and stopping procedures for centrifugal pumps?
- Before using the centrifugal pump, the operation instructions of the centrifugal pump shall be read carefully and the specific operation procedures shall be understood so as to make proper use of the centrifugal pump products. The first step is the operation of centrifugal pump inlet valve of centrifugal pump centrifugal pump for all open cavity filled with liquid, close the outlet valve, start the motor, the motor speed is normal, can gradually open the outlet valve, to adjust to the desired condition. Pay attention to self suction centrifugal pump starts to open the exhaust valve, outlet valve should be opened quickly in the normal operation of the motor, to prevent air inlet pipe off caused by cavitation phenomenon produces centrifugal pump, centrifugal pump vibration phenomenon leads to noise of the smoke is not on the water.
- 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: Is the flow meter in front of the pump or after the pump?
- After the flowmeter is placed in the pump, it is better to add a pressure tank or a buffer tank, so that the flow meter will work better
- Q: What is the nominal pressure of the hydraulic pump and hydraulic motor?
- Rated flow refers to the flow under the rated speed and rated pressure input to the motor.Due to leakage loss, the actual flow of the input motor must be greater than its theoretical flow. Actual flow of motor (i.e. inlet flow) leakage flow = theoretical flow of the motor.
- Q: Which nuclear submarines use the shaftless pump technology?
- At present, the submarine has been used in the pump jet technology, the most representative is the United States Virginia class submarine and the Russian North Sea God class submarines.. And shaftless pump is a derivative application of superconducting technology, which is more advanced than pump jet technology..If you want to learn more about shaftless pump technology, you can find relevant papers online.
- 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
