What is the reason for running while the heavy gravity machine?

A hydrometer, also known as a density meter, is made according to Archimedes' law and the condition that an object floats on the liquid surface in equilibrium, and is an instrument for determining the density of liquids. It is a closed glass tube, one end of the thickness is uniform, the inner wall is pasted with a scale paper, the scale is uneven, the top is sparse and the bottom is dense, and the other end is slightly enlarged and foam-like, and the bubble is filled with small lead particles or mercury, so that the glass tube can be vertically immersed in the liquid to a sufficient depth, and can float stably in the liquid, that is, when it is shaken by any kind of shaking, it can automatically return to a vertical stationary position. When a hydrometer floats in a liquid, its gravity is equal to the gravity of the liquid it distributes.

Therefore, different liquids are immersed at different depths and under different pressures, and the hydrometer uses this relationship scale. There are two kinds of hydrometers commonly used, one is used to measure the density of liquids with a density greater than 1, called "weight table"; Another method used to measure the density of liquids with a density of less than 1 is the measuring principle.

The long tube of a hydrometer [2] is often marked with the following numerical scale3……。When the hydrometer sinks to the scale of the liquid, it is immediately known that the density of the measured liquid is.

With this instrument, the object simply sinks to a depth where the weight of the liquid it excludes is exactly equal to its own weight. As a result, a hydrometer sinks deeper in a lighter specific gravity liquid than in a heavier liquid. For example, it will sink deeper in alcohol than in alcohol mixed with water; It is shallower in plain milk than in milk mixed with water.

The hydrometer is inserted into various liquids with decreasing specific gravity in turn, such as sulfuric acid (, water (, ether (, etc.), and the depth of its sinking is gradually deepened. Therefore, the larger specific gravity must be located in the lower part of the scale, and the smaller specific gravity must be located in the upper part of the scale. Of course, the scale itself must be calibrated first, and it must also be calibrated according to the specific gravity of each liquid, or directly according to the special properties of the liquid being measured, such as the alcohol content of wine, the fat content of milk, the pure acid content of sulfuric acid, etc.

The crane deviation will lead to the vehicle air bridge, which is a large vehicle after the crane is used for a period of time. The phenomenon of walking is only a driving car that has been used for many years. Refund.

The large traffic between the enteritis material workshop and the retreat train is walking, and the equipment failure often occurs due to serious Kenqing. The consumption of spare parts for intermediate equipment and the maintenance workload affect the normal production of the workshop.

The reasons for belt deviation of the belt sander are none other than the following 3 types:

First, the abrasive belt continues to experience lateral thrust in one direction.

Second, the axes of the guide roller, drive roller and contact roller of the belt grinding machine are not parallel.

Third, the abrasive belt is loose and tight.

When the angle grinder is grinding, polishing, or cutting, the grinding wheel will produce a reaction force when working because of the direction of rotation, so it will show the phenomenon of the angle grinder running to the side, which is very normal. Therefore, when the angle grinder is working, the hand should be held firmly to prevent the angle grinder from hurting the operator.

The grinder will only run to one side, it may be that you are holding the grinder out of balance, you can find a balance point, and he will not run to the side.

The grinder runs to the side, at this time you have to check whether the eccentric wheel is normal and whether the tension of the belt is normal? Is the speed of the motor normal? If the following is not normal, it will deviate to one side.

Make a small hole in it. That is, two heads to fight. For example, if you drill 160 holes and the drill bit is stuck at a depth of 200 and the whole wall is 400 thick, then use 63 heads outside the wall to hit 200 deep, and then use a hammer and steel drill to hit it.

1) Cause of failure:

1) The inside of the oil cup is too dirty, the filter screen is blocked, or the oil level of the oil cup is low.

2) There is a lot of air in the power steering system.

3) There is a foreign object in the steering system, which causes the flow control valve of the steering pump to get stuck.

4) The tire pressure is insufficient, the steering column of the pump interferes, the connection is loose, the belt of the pump is loose, slipping or the pump installation position is loose.

5) The bolts of each connection part of the tubing are loose, resulting in the leakage of steering fluid.

6) The piston cylinder of the steering gear is worn too much, the oil seal is poorly sealed, and the control valve is bonded or damaged.

The grinding machine is a manual power tool used to polish the surface of metal. The polishing machine is specially designed for the surface and tube treatment of steel, aluminum and copper and other metal products, and dozens of original accessories meet different needs, and it is easy to manufacture a variety of snowflake patterns, brushed lines, wave patterns, matte surfaces, mirror surfaces, etc. with different precisions, quickly repair deep scratches and slight scratches, and quickly polish and polish.

The grinder is out of order and needs to be repaired.

Is there something wrong with the settings, or is the polished thing out of line?

Why did I forget to just run to the side? Is it too old? Need to fix it? I can't use it long if I forget me.

Is the motor muddy? Can check it out.

Hello, according to your description, if the steering wheel of your car changes, this is normal, because after the steering wheel changes the regularity, all the auspicious data will change. After changing the direction of the machine, you need to do four-wheel alignment, and the direction after the data correction will deviate if you don't lift the banquet booth.

Under the normal situation of the positive burning, the differential of the direction of the car and the rear-wheel drive part slows down the inner bending movement and the outer bending movement is fast, so that the generator turns to the movement. When the car encounters water or oil, the static friction is less, the speed of the two wheels is equal, and it cannot turn.

Check the status of the sensor when the sensor is malfunctioning or malfunctioning.

The upper computer command is incorrect. or the screw coupling is loose.

The biggest cause of this problem is interference, do a good job of wiring.

The electronic gear ratio is incorrect, please check.

Generally, it has nothing to do with tightening, and there may be some problems during installation, but this phenomenon is more common.

Search: When the slitting shear is rewinded, does the sheet running to the side have anything to do with the tensioner?

Hello, see if the correction shelf is installed correctly, if it is not for this reason to adjust the position of the correction sensor, you can ask the antenna about the correction device.

First, the temperature regulation is not suitable.

Second, the upper and lower rollers are not synchronized.

Third, the thickness of the laminated paper itself is uneven.

It should be that after touching this switch, the control part that controls the direction of the cutting machine has come into play
