1. Smooth mechanism

Smoothing is to add smoothing agent between the two conflict surfaces of relative motion, so that a smooth film is formed between the two conflict surfaces, separating the dry conflict surface that is originally directly touched, and turning the dry conflict into a conflict between the molecules of the smoothing agent, so as to reduce the conflict, reduce wear and tear, and extend the service life of machinery and equipment.

1. Smooth effect

(1) After manipulating the smoothing between the conflict surfaces, because the smoothing agent is between the two conflict surfaces, the two conflict surfaces are separated, so that the dry conflict becomes the conflict between the smoothing agent molecules, so the conflict coefficient and conflict resistance between the conflict surfaces are different with the smooth state between the conflict surfaces.

(2) The reason why smoothness can reduce wear is that smoothness can reduce conflict, reduce conflict to a minimum, and avoid bite welding and tear wear on the metal surface. In addition, the cleaning effect of liquid smoothing agent is also effective in cleaning dust, metal abrasive particles and other impurities on the conflicting surface of the machine parts to avoid wear.

(3) In the process of cooling and cooling machinery and equipment, it is necessary to overcome the conflicts on each conflict surface and do work, and the work spent on overcoming the conflict has been converted into heat. As a result, the surface temperature of the conflict rises, causing the thermal deformation of the metal to reach the melting point of the metal, and the adhesion of the conflict surface. The smoothing agent is a good heat dissipator, which can bring the heat to the cooling surface in time to dissipate.

(4) To avoid the conflict surface rust The conflict appearance of various machinery is inevitably in contact with the surrounding media such as air, water droplets, water vapor, corrosive gases and liquids, dust, oxides, etc., which makes the metal surface rusty, corroded and damaged. When the collision surface is covered with smoothing agent, the resulting rust can be avoided.

(5) The sealing effect, such as lipids, has a self-sealing effect, which can not only avoid the loss of smoothing agent, but also avoid the invasion of water impurities. In compressors, there is a high degree of sealing between the cylinder and the piston, and the hydraulic oil used for hydraulic transmission is also sealed.

(6) Transmission of power such as hydraulic transmission

(7) The vibration absorber of the car (motorcycle) is to use oil to absorb the shock, the piston moves up and down in the closed fluid cylinder, and the oil in the cylinder flows from one end to the other end against the direction of the piston movement, and the body vibration is lost after the conflict of the liquid.

2. The importance of smooth equipment

Equipment is one of the elements of enterprise production. In order to make the equipment in a good technical state, it is necessary to pay attention to the maintenance of the equipment during its use, and make it smooth reasonably and perfectly. Only in this way can we control conflicts, reduce wear, reduce the energy consumed in the transmission mechanism, extend the life of the equipment, reduce equipment damage and faults, and reduce repair costs. Therefore, the smoothness of equipment is directly related to saving power, materials and manpower, improving the quality, reliability, life and safety of mechanical products, and creating more material wealth.

According to one calculation, more than one-third of the world's power is lost in various forms in the process of transferring energy by various machinery.

3. The reason for cleaning and changing the oil of the equipment

Smooth oil (grease) is subjected to heat, agitation and mechanical shear due to the conflict of mechanical action in the process of application, coupled with the influence of the surrounding environment, such as the invasion of air, water vapor, dust, metal particles, etc., which gradually oxidizes and deteriorates, producing gum, asphaltene and acidic substances, so that the function declines, until it can not be used continuously. If it is used continuously, it will corrode the parts, block the oil system, and a large number of abrasive particles will be brought back into the conflict surface, resulting in trench grinding. Therefore, it is very necessary to develop an oil change interval.

Second, the common smooth method

1. The technical refueling (grease) is smooth, and the operator regularly uses the oil pot or oil gun to refuel the oil hole and oil cup

2. The oil dripping smooth uses the oil to pass through a controllable small hole in the oil dripping equipment under the action of gravity, and drip oil smoothly to the smooth part at a certain time.

3. The oil rope and oil pad are smooth, one end of the oil rope and the oil pad is immersed in the oil pool, and the other end is directly touched with the movement surface of the conflict pair, and the oil enters the conflict pair for smoothing by using the capillary action.

4. The smoothness of the oil ring or oil chain is to put the oil ring or oil chain on the journal, so that the lower part is immersed in the oil pool, when the shaft rolls, the oil ring is driven to rotate by the conflicting force, so as to bring the oil into the bearing for smoothing.

5. The smooth method of immersing the conflicting appearance into a smooth oil pool in an oil bath or splash smooth is called oil bath smooth. The smoothing method of splashing the smooth oil in the oil pool onto the collision surface by means of a moving machine that rotates in the oil pool or an oil throwing disc or oil throwing disc attached to the shaft is called splash smoothing. The most typical equipment with oil baths and splash smoothness is a closed gearbox.

6. Forced smoothing is forced to form an oil wedge or oil film on the conflicting surface through the external pressure oil, such as the use of smooth oil stainless steel multistage pump and so on.

For example:

1. The rolling bearing adopts oil bath or splash smooth together with smooth oil ring, such as the general horizontal centrifugal stainless steel multistage pump.

2. The sliding bearing adopts forced smoothness, such as oil supply through the oil stainless steel multistage pump.

3. The crankcase is smooth with oil bath.

3. Maintenance mechanism of stainless steel multistage pump

1. Oil standard: a simple communicator principle, maintain a certain liquid level, easy to observe, usually planned to keep the normal liquid level at half to two-thirds of the full height. Structural features, glass tube, with openings, discharge plugs on the side and so on

2. Oil cup: also known as constant oil level oiler. Features: Negative pressure liquid column balance principle, inclined plane planning of discharge outlet, liquid level low point control.

3. Oil seal: the form is mostly labyrinth or centrifugal. But it is only a dynamic seal, a non-static seal, so it does not have the best sealing conditions, and it will overflow if you add too much oil.

4. The gas release plug is generally located next to the oil filling plug to balance the pressure inside and outside the fuel tank to discharge excess gas, and can avoid the invasion of dust.

5. The shell wall is mostly made of fin type, which is convenient for timely heat dissipation.

6. The water-cooled jacket is mostly a fin casing type.

7. Commonly used in fan blade motors, stainless steel multistage pumps can be used as optional parts.

8. Frequently Asked Questions:

(1) The oil level is too low, the oil bath is not sufficient, and the oil is not easy to carry to all the conflict surfaces above, resulting in dry grinding and burning of bearings. Generally, the normal oil level should be planned to be 1/3 to 2/3.

(2) The phenomenon caused by too much oil is that the heat dissipation space is small, and the oil is simply overheated, which first affects the function of the grease and reduces the smooth effect. Together, it is easier to dissolve too much gas under strong agitation, so that the phenomenon of oil foam (that is, bubbles in the oil) is produced. It destroys the balance of the oil cup, and the infinite injection will increase more and more, and the more and more this phenomenon will occur, forming a vicious circle.

(3) The deterioration of oil quality is generally caused by expiration, water ingress or other impurities, emulsification, mixing of different oils, etc.
