Product Description:

Structure and operating principles of Portable Self-priming Single Suction Centrifugal Pump

 

Diesel engine driven self-priming pump is composed of diesel engine, coupling, pump body, impeller, rear cover, mechanicalseal, pump spindle, bearing block, imported pump, gas-liquid separator tube, water valve and drain connection. The structure of the pump is shown in the following figure.

Principle of operation: The pump body with fluid reservoir inside and the working chamber of the pump, being connected with each other through the reflowingvalve on the upper side and circulation valve beneath it, form the axial-flow outer recirculation system of the pump. When the pump stops working, it already has a volume of liquid reserve inside its fluid reservoir, when the pump runs, the liquid inside is ejected upward with the air flow under the function of impeller, then it reflows into the working cavity through the gas-liquid separator tube, at the same time, the gas is exhausted out of the pump, which makes the pump vacuumed inside so as to get self-priming realized.

 

Preparations of Portable Self-priming Single Suction Centrifugal Pump

 

  • Check the fasteners of the joint parts, such as the pump seat, the coupling and the bearing carrier, and make sure that they would not loosen. If any of them get loose, you should fasten them.

  • Check the connecting pipes and make sure that there is no gas leakage.

  • Switch on the water valve on the top of the pump, add a volume of water,which is no less than 2/3 of the pump volume. Then switch off the water valve. The next time you start the pump, you never need to do water-injection anymore.

  • Get the power line of the storage battery routed to the power source , when the diesel engine is power-on, press down the starting button of the meter panel,  give it a test run to see if it rotates clockwise (counterclockwise rotation is prohibited). 

  • Starting up: Add antifreezingsolution to the water tank of the diesel engine, and fill the fuel tank with diesel oil,then add some lubricating oil (labeled 10w-40)to the engine. Route the power line of the starter to the storage battery and pay attention to the positive and negative poles.

Q:About how to calculate the pump installation height?
See the design manual, town water, volume P312This formula is: NPSHA = HgHzhsZs > NPSHRAccording to the actual installation of NPSHA pump cavitation can provideThe pump NPSH provides NPSHR pump samplesAtmospheric pressure Hg pump installation siteHz liquid under certain temperature saturated steam pressure.The head loss of water pipe HsThe installation height of ZsIt is worth pointing out that, with regard to Hz, with temperature related, and some problems are not given temperature, and that value is also very small, in the calculation should be able to ignore (0 degrees C, 0.06mH2O).And atmospheric pressure, we usually use 10mH2O, in fact, and altitude also related. When the altitude is 0, it is 10.3
Q:Yang Chengtai big, the pump power is too small, the water pump will be bad?
No, only when the operation of the low lift point is super power (burning motor), high lift point operation, low efficiency, small amount of water, or even no water. For example, a nominal 10 meters pump, flow rate of 10 square / hour. The actual lift 15 meters, the water pump is small or no water. The actual head is 5 meters, traffic may 20 square / hour, this time may exceed current, the motor may burn.
Q:Pump suction and pressure side road why should vacuum table and pressure gauge, and what role they have?
The pump suction and pressure side roads shall be equipped with a vacuum meter and a pressure gauge to monitor the operation of the system. When the pump is running, if the suction side of the vacuum decreases, indicating that the performance of water pump or water absorption pipe leakage; if the vacuum increases, it may be blocked suction pipe. The pressure on the water side is too large. It may be less water or the water pipe is blocked. If the pressure drops, the water consumption may increase or the water pump performance will decrease.The pressure gauges on the water side also play an important role in observing the pressure changes at the start of the pump to determine when to open the outlet valve. Usually larger pump starts, should first close the outlet valve to reduce the starting current, until the pressure of the pump rising and stable, then open the outlet valve.
Q:Water pump 50HZ impeller and 60HZ what is different, why not the same?
60Hz pump and 50Hz pump itself is not much difference, just that the motor speed, the rated speed is 3600 rpm, 1200 rpm, 1800 rpm, the latter is generally 3000, 1500, 1000 etc.. If it is to use the same pump, the difference is that the 60Hz motor pump flow is 50Hz, motor water pump flow of 1.2 times, the lift is 1.2*1.2=1.44 times, power is 1.2*1.2*1.2=1.728 times. So in the actual manufacture, especially some relatively large flow lift pumps, pump motor using 60Hz to use 50Hz thicker than the spindle motor of the pump impeller, the difference between the two, in addition to empty size shaft is different, what basically no difference. As for the data of package angle, the water conservancy models of different factories are different, but I don't know whether there is any difference between them. Most of them make no difference. However, if you want to use the 60Hz pump to achieve the same flow rate as the 50Hz pump, the impeller of the former should be cut to 0.833 times the size of the latter.
Q:Flow 70 cubic meters per hour; lift 35 meters, choose what standard water pump?
1, what liquid transport, whether corrosive, there are no metal particles, or other dirty things2. Installation form (submerged pump, pipeline pump)Clear these issues, you can choose the pump according to requirements
Q:How do I calculate the power of the pump?
A 15kw pump, know how to calculate the head pumping water for an hour (if the head is 10 meters)Lift: MFlow rate: kg / sec (general water pump is cubic / hour, if 10 cubic hour / hour: 2.7 kg / sec)Efficiency: average 60%15000/102*0.6=88 kilograms per second88/10=8.8 kg / sec8.8*3600=31680 kg / h=31.6 cubic / hour
Q:Should the no-load power of the pump be equal to the rated power?
We must first clear the meaning of rated power; rated power is called the reference numerical electrical power consumption in the voltage conditions specified, and the actual power consumption of electrical appliances is different in different situations, the pure resistance (such as lighting, electric) as long as the voltage conditions, the actual consumption of electric power close to or equal to the rated power, and for appliances like motor, electric power consumption, not only related with the voltage, but also with the relevant load. For example, someone with 200 pounds of energy, then the person in the condition of small meal, maximum load of 200 pounds, but if you take as long as he is 100 pounds, of course he relaxed, he would not say must bear 200 pounds!You measure the pump power is less than 1200W, first you did not mention your use of voltage is not rated voltage, then you don't want him full load, the suction is far less than 8 meters, there is no mention of whether you send water to 50 meters (Yang Cheng), there may be insufficient voltage, and you have don't need it so much power consumption. Of course, one advantage is that it doesn't burn easily. It is easy to burn if it is used at full load.
Q:Stop the engine immediately and stop the circulating pump and the condensate pump. What's the harm to the turbine?
Then look at what is the circulating water pump and condensate pump users, circulating water with oil in the oil cooler then, condensed water supply pump seal water, water pump can't pump up, how will you know.
Q:What's the function of the engine pump?
The function of the water pump is to pressurize the coolant, and ensure that it circulates in the cooling system. Generally speaking, the water circulates continuously through the radiator, engine block and parts. Take away heat.. Ensure that the engine is not high temperature
Q:What's a small soft pipe for a submersible pump in a fish bowl? How do you use it?
Filter pump for oxygen spray. If the filter pump water flow, you can throw oxygen flowers, you can not use. With that pipe, it's loud and kind of
