Precautions When Using Water Pump
- If the water pump has any small fault, remember not to let it work. If the packing of the water pump shaft is worn, it should be added in time. If the water pump continues to be used, it will leak. The direct impact of this is that the motor energy consumption will increase and the impeller will be damaged.
- If a strong vibration occurs during the use of the water pump, you must stop and check the cause, otherwise the water pump will be damaged.
- When the bottom valve of the water pump leaks, some people will fill the inlet pipe of the water pump with dry soil and flush it with water, which is really not advisable. Because when the dry soil is put into the water inlet pipe, when the pump starts to work, the dry soil will enter the pump, which will damage the pump impeller and bearing, thus shortening the service life of the pump. When the bottom valve leaks, it must be repaired. If it is serious, it needs to be replaced.
- The water pump must be maintained after use. For example, when the water pump is used up, the water in the water pump should be drained. It is better to remove the water pipe and wash it with clean water.
- The tape on the water pump should also be removed, washed with water and dried in the light. Do not put the tape in a dark and damp place. The adhesive tape of the water pump must not be stained with oil, let alone coated with something sticky.
- Carefully check whether there are cracks on the impeller and whether the impeller is loose on the bearing. If there are cracks and looseness, repair them in time. If there is mud on the pump impeller, clean it up.
Technical questions and answers about pumps
What should be done before the maintenance of the chemical pump?
A: 1) the machine and equipment must be shut down, cooled, depressurized, and cut off the power supply before maintenance;
2) Machines and equipment with inflammable, explosive, toxic, and corrosive media must be cleaned, neutralized, and replaced before maintenance. Construction can only be carried out after passing the inspection;
3) For the maintenance of equipment, machines, and pipelines with flammable, explosive, toxic, and corrosive media or steam, the inlet and outlet valves of materials must be cut off and blind plates must be added.
What process conditions should chemical pumps have before maintenance?
A: 1) stop; 2) Cooling; 3) Pressure relief; 4) Cut off the power supply; 5) Displacement
What are the general principles of mechanical disassembly?
A: Generally speaking, it should be disassembled from the outside to the inside, from the top to the bottom, and as far as possible, the whole parts should be disassembled as a whole.
What causes the power loss in the centrifugal pump?
A: there are three kinds of losses: hydraulic loss, volume loss, and mechanical loss.
1) Hydraulic loss: when the fluid flows in the pump body if the flow channel is smooth, the resistance will be smaller, and if the flow channel is rough, the resistance will be larger. When the water enters the rotating impeller or when the water comes out of the impeller, it will also produce collision and vortex, causing losses. The above two losses are called hydraulic losses.
2) Volume loss: the impeller is rotating, and the pump body is static. A small part of the fluid flows back to the inlet of the impeller in the gap between the impeller and the pump body; In addition, some fluid flows back from the balance hole to the impeller inlet or leaks from the shaft seal. If it is a multi-stage pump, a part of the balance plate will also leak. These losses are called volume losses;
3) Mechanical loss: when the shaft rotates, it will rub with bearings, fillers, etc., the impeller rotates in the pump body, and the front and rear cover plates of the impeller will rub with the fluid, which will consume part of the power. These losses caused by mechanical friction will always become mechanical losses.
In production practice, what is the basis for rotor balancing?
A: according to different revolutions and structures, the static balance method or dynamic balance method can be selected. The static balance of the rotating body can be solved by the static balance method. Static balance can only balance the imbalance of the center of gravity of the rotating body (i.e. eliminate the torque), but cannot eliminate the unbalanced couple. Therefore, static balance is generally only applicable to disk-shaped rotating bodies with a relatively small diameter. For the rotating body with a large diameter, the problem of dynamic balance is often more common and prominent, so it is necessary to deal with dynamic balance.
What is the balance? How many kinds of balance?
A: 1) the work of eliminating the imbalance of rotating parts or components is called balance;
2) Balance can be divided into static balance and dynamic balance.
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) and a starting protection de
