Maintenance Tips about Water Pump
The water pipe must be highly sealed, and the connection between water pump and water pipe must be checked for looseness.
Add bearing lubricating oil to the bearing body to observe that the oil level should be at the center line of the oil pointer, and the lubricating oil should be replaced or replenished in time. After the oil immersed water pump works for 500 hours, it is necessary to replace the sealing oil. The oil in the pump motor cavity should also be replaced once a year,
Close the gate valve, outlet pressure gauge and inlet vacuum gauge of the outlet pipe of the water pump.
Inch the water pump motor to see if the rotation direction of the water pump motor is correct. Start the water pump motor. When the water pump operates normally, open the outlet pressure gauge. If the pressure is appropriate, gradually open the gate valve, and check whether the water pump motor has any load.
The flow and lift of the water pump shall be controlled within the specified range as far as possible to ensure that the water pump operates at the highest efficiency point, to obtain the maximum energy saving effect.
During the operation of the water pump, the bearing temperature shall not exceed the ambient temperature by 35C, and the maximum temperature shall not exceed 80C.
In case of any abnormal sound from the water pump, stop the pump immediately to check the cause. Before stopping the water pump, close the gate valve and pressure gauge first, and then stop the water pump motor.
Regularly adjust the packing gland to ensure that the leakage in the packing chamber is normal.
Regularly check the wear of the water pump shaft sleeve, and timely replace it if it is worn seriously.
If the water pump is out of service for a long time, it is necessary to disassemble all the water pumps, wipe off the water, coat the rotating parts and joints with grease and install them properly.
Mechanical seal lubrication shall be clean and free of solid particles. It is forbidden to work the mechanical seal under dry grinding.
The pump is cavitating. Are you afraid?
What is cavitation?
When the local pressure of the liquid in the pump drops to the critical pressure, bubbles will be generated in the liquid. Cavitation is the whole process of bubble accumulation, movement, division, and elimination. The critical pressure is generally close to the vaporization pressure.
What are the hazards of cavitation?
corrosion of overcurrent components
There are two reasons for corrosion:
First, high frequency (600~25000hz) impact occurs when the bubble bursts and the pressure is as high as 49MPa, resulting in mechanical denudation of the metal surface;
The second is that heat is released during vaporization, and hydrolysis is produced by the action of a thermoelectric battery. The oxygen produced oxidizes the metal and causes chemical corrosion.
pump performance degradation
When the pump is cavitating, the energy exchange in the impeller is disturbed and destroyed, and in serious cases, the liquid flow in the pump will be interrupted and cannot work.
For low specific speed, due to the narrow and long channel between blades, once cavitation occurs, bubbles fill the whole channel, and the performance curve will suddenly drop.
For medium and high specific speed, the flow channel is short and wide, so it needs a transition process from the occurrence and development of bubbles to filling the whole flow channel, and the corresponding performance curve begins to decline slowly and then increases to a certain flow rate before it drops sharply.
Parts of centrifugal pump most prone to cavitation
The front cover plate with the largest curvature of the impeller is near the low-pressure side of the blade inlet edge; The low-pressure side near the inlet edge of the volute diaphragm tongue and guide vane in the press-out chamber; The sealing gap between the outer circle of the blade tip and the shell of the high specific speed impeller without the front cover plate and the low-pressure side of the blade tip; The first stage impeller in multi-stage pump.
Improve anti-cavitation measures
Measures to improve the cavitation resistance of the centrifugal pump
Improve the structural design from the suction port of the pump to the vicinity of the impeller. Increase the overflow area; Increase the curvature radius of the inlet section of the impeller cover plate to reduce the sharp acceleration and pressure reduction of the liquid flow; Properly reduce the thickness of the blade inlet and round the blade inlet to make it close to the streamline can also reduce the acceleration and pressure reduction of the head of the bypass blade; Improve the surface finish of impeller and blade inlet to reduce resistance loss; Extend the inlet edge of the blade to the inlet of the impeller to make the liquid flow accept work in advance and increase the pressure.
The front inducer is used to make the liquid flow work in advance in the front inducer, to improve the liquid flow pressure.
The double suction impeller is adopted, so that the liquid flow enters the impeller at the same time from both sides of the impeller, the inlet section is doubled, and the inlet flow rate can be reduced by one time.
The design working condition adopts a slightly larger positive angle of attack to increase the blade inlet angle, reduce the bending at the blade inlet, reduce the blade blockage, and increase the inlet area; Improve the working conditions under large flow to reduce the flow loss. However, the positive angle of attack should not be too large, otherwise, the efficiency will be affected.
Anti cavitation materials shall be used. Practice shows that the higher the strength, hardness, and toughness of the material, the better the chemical stability and the stronger the cavitation resistance.
Measures to improve the effective NPSH of the liquid inlet device
Increase the pressure of the liquid level in the liquid storage tank in front of the pump to improve the effective NPSH.
Reduce the installation height of the suction device pump.
Change the suction device into a backflow device.
Reduce the flow loss on the pipe in front of the pump. For example, try to shorten the pipeline within the required range, reduce the flow rate in the pipeline, reduce bends and valves, and try to increase the valve opening.
Reduce the temperature of the working medium at the pump inlet (when the conveying working medium is close to the saturation temperature).
The above measures can be comprehensively analyzed and appropriately applied according to the pump type selection, material selection, and the conditions of the pump site.
Application field
① In the production of chemical and petroleum sectors, most of the raw materials, semi-finished products and finished products are liquids, and the production of semi-finished and finished raw materials into semi-finished products and finished products needs to go through complex technological processes. During these processes, pumps play a role in transporting liquids and providing pressure flow for chemical reactions. In addition, in many installations, pumps are used to adjust the temperature.
② In agricultural production, pumps are the main irrigation and drainage machinery. my country's rural areas are vast, and a large number of pumps are needed in rural areas every year. Generally speaking, agricultural pumps account for more than half of the total output of pumps.Pumps are also the most used equipment in the mining and metallurgical industries. The mine needs to be drained by pumps, and in the process of beneficiation, smelting and rolling, pumps are needed to supply water.
③ In the power sector, nuclear power plants need nuclear main pumps, secondary pumps, and tertiary pumps, and thermal power plants need a large number of boiler feed pumps, condensate pumps, oil and gas mixing pumps, circulating pumps, and ash pumps.
④ In national defense construction, the adjustment of aircraft flaps, tail rudders and landing gear, the rotation of warships and tank turrets, and the ups and downs of submarines all require pumps. High pressure and radioactive liquid, and some also require the pump without any leakage.
⑤ In short, whether it is aircraft, rockets, tanks, submarines, drilling, mining, trains, ships, or everyday life, pumps are needed everywhere, and pumps are running everywhere. That's why the pump is listed as a general-purpose machine, which is a major product in the machinery industry.
⑥ Electric pumps, i.e. pumps driven by electricity. The electric pump is composed of a pump body, a water lift pipe, a pump base, a submersible motor (including cables)
