The principle of pressurized water wells, how to press water wells

How pressurized water wells work.

Pressurized water wells have a piston on the top and a valve on the bottom, and this piston and valve are both a one-way valve.

When the piston goes up, the valve opens, and the air in the lower tube can be pumped into the upper cavity, and when the piston goes down, the valve closes, and the air comes out from the side of the piston, so that the circulation will pump the pipe below into a vacuum, and the water is at atmospheric pressure.

Under the effect of being pumped up, but sometimes the sealing is not good, the air outside will leak in when the piston goes up, and when the piston goes down, the air in the cavity may also leak from the valve into the pipe below, so that it is difficult to evacuate the pipe, because the water has a certain sealing effect, plus the sealing effect is improved, the water can be pumped up soon, and the role of water diversion is sealing.

In fact, in many places where the water level is relatively high, pressurized wells can generally pump water without water diversion.

It's just the reason why groundwater has a high alkali content.

Pressurized water wells also apply the principle of machinery (lever), "three points": fulcrum, resistance point, and force point are all on the long handle.

Pressurized water well is a kind of tool to lead groundwater to the ground, it is made of cast iron, the bottom is a cement-type block, the head of the well is the outlet, the back is thick and thin, the tail is the pressure handle connected with the well core, about twenty or thirty centimeters long, often used, to make it brighter, the center of the well is a piece of water diversion skin, relying on the force of this water diversion skin and the well core to lead the groundwater pressure up.

Pressurized water well uses the principle of negative pressure, when you press down, a vacuum is formed inside the cylinder body, and the water is sucked up, when returning, the valve at the bottom of the cylinder body is automatically closed, and the water flows out from the upper valve, so repeatedly, the water is drawn up, in fact, it is a piston with two one-way valves.

1. Prepare an iron pipe that can be held by both hands, or the iron pipe can be cut off and processed into several short iron pipes, which is convenient for connection during construction; 2. Dig a small pit first, pour some water into the pit, put the iron pipe made in advance vertically into the pit, lift it vigorously, then press the iron pipe hard, and repeat the operation until the iron pipe is drilled to a suitable water layer underground; 3. During the period, water should be continuously added to the pit, and then the iron pipe will be raised, and a borehole will appear on the ground, a plastic pipe will be placed in this borehole, and the ground borehole stool will be sealed around, and a vacuum pumping device will be installed at the upper end of the pipe, or the piston and the tie rod jujube Yuhe will be used to reciprocate and dismantle in the pipe, so that the pressure of the well can be completed.

The principle of pressurized water well: there is a piston above the pressurized water well, and there is a valve below, and the piston and valve are a one-way valve, so that the air goes up and not down, and when the piston goes up, the valve is opened, and the air in the pipe below can be pumped to the upper cavity;

As the piston goes down, the valve closes, and air comes out of the side of the piston, and in this way the tube below is pumped into a vacuum, and the water is pumped up under the action of atmospheric pressure.

The working principle of the pressure well is a one-way valve, so that the air goes up and not down, when the piston goes up, the valve opens, the air in the pipe below can be pumped to the upper cavity, and the water is pumped up under the action of atmospheric pressure.

Specifically, the pressurized water well, there is a piston above, there is a valve below, this piston and the valve are a one-way valve, so that the air goes up and not down, when the piston goes up, the valve opens, and the air in the pipe below can be pumped to the upper cavity.

When the piston goes down, the valve is closed, and the air comes out from the side of the piston, so that the circulation will pump the pipe below into a vacuum, and the water will be pumped up under the action of atmospheric pressure, but sometimes the seal is not good, and the air outside will leak in when the piston goes up, and when the piston goes down, the air in the cavity may also leak from the valve into the pipe below.

In this way, it is difficult to evacuate the pipe, because the water has a certain sealing effect, and the sealing effect is improved after the water, and the water can be pumped up soon, and the role of water diversion is sealing.

Summary. Hello, 1. First of all, let's make the cylinder of the pressurized water well. Find a tube with a diameter of 12 cm and a length of 50 cm, and make a small hole at 35 cm of the cylinder with a diameter of 8 cm, and the cylinder is ready.

2. Make a pressure handle. Find a steel pipe with a diameter of 3 cm and a length of 80 cm, weld a loose leaf at 35 cm at one end and make a 1 cm empty at the front end.

3. Piston production. Make one end of a 40 cm long No. 12 steel bar with a thread buckle, and bend the other end into a 1 cm long hook at 90 degrees. Attach the piston and spring to this tie rod.

4. Wellhead production. At home, use cement to fix the cylinder of this pressurized water well at the wellhead, and it must be fixed and strong.

5. Installation of pressurized water wells. Now it is time for the most critical part, that is, the installation, put the piston pull rod made in advance into the cylinder, then connect the pressure handle to the cylinder, and finally connect the front end to the piston pull rod.

6. Welding of the outlet of the pressurized water well. Now that everything is installed, we find an 8 cm steel pipe with a slope of 140 degrees at one end, and weld the slope to the outlet of the pressurized water well.

7. Completion of experiments. After we are done, we will try the results of our burial feast, bring a basin of water, pour it into the pipe body of the pressurized water well, and now press the hand up and down to see if the water is out of the water.

Hello, glad to answer for you. The confined water is located between two stable aquifers, with a pressure head, which is generally not directly affected by meteorological and hydrological factors, and has the characteristics of being more stable, and the water quality is not easy to be polluted.

The method is as follows: 1. Prepare an iron pipe that can be held by both hands, or the iron pipe can be cut off and processed into several short iron pipes, which is convenient for connection during construction;

2. Dig a small pit first, pour some water into the pit, put the iron pipe made in advance vertically into the pit, lift it hard, and then press the iron pipe hard, and operate the wide silver repeatedly until the iron pipe is drilled into a suitable water layer underground;
