Pig Drinker Introduction
There are many types of automatic drinking fountains for pigs, but the most commonly used ones are duckbills, nipples, cups, and the like. Today, we will give a detailed introduction to these three types of drinking fountains.
Duckbill pig drinking fountain
At present, there are many duck-bill drinking fountains used in pig farms, because the duck-billed drinking fountains have better sealing performance, and the water flow rate and pressure are more in line with the requirements of pig drinking water. Duckbill pig drinking fountains are generally available in two sizes. One is a small duckbill drinker for suckling pigs and nursery piglets. The flow rate is generally 2~3L/min; the average pig and big pig are used. Large duckbill drinker with a flow rate of 3-4L/min. Regardless of the type of drinker used, the ultimate goal is to meet the needs of pigs for drinking water.
The structure of the duckbill pig drinking fountain generally comprises a valve body, a valve core, a sealing ring, a return spring, a plug cover, a filter screen and the like. The valve body and the valve core are mainly made of brass and stainless steel. The spring and the filter mesh are mostly made of stainless steel, and the plug cover is made of engineering plastic. The overall structure of the duckbill pig drinking fountain is relatively simple, corrosion resistant, watertight, long life and stable working performance.
The working principle of the duckbill pig drinking fountain is that when the pig drinks water, the mouth contains a drinking fountain, bite the valve stem, the water will flow out from the gap between the valve core and the sealing ring, and enter the pig's mouth; when the pig's mouth is loose After opening, the spring is pulled back, the valve stem is returned, and the water stops flowing.
The duckbill drinker can be installed in two forms, one is horizontally mounted and the other is mounted at 45° to the horizontal. The height of the drinker from the ground changes with the weight of the pig. However, the drinker must be kept away from the rest area of the pig when it is installed. In addition, during the use of the drinker, it is necessary to regularly check the working state of the drinker, remove the mud, adjust and tighten the screws, and find the fault to replace the parts in time.
Nipple pig drinking fountain
In addition to the duckbill-type pig water drinker, the nipple-type drinker is also a drinking water device that is currently used in pig farms. The biggest feature of the nipple drinker is that the structure is relatively simple, and it is generally composed of a shell, a valve core, a sealing ring, a return spring, a plug cover, a filter mesh and the like. The advantage of the nipple drinker is that it has a strong ability to pass impurities in the water.
The working principle of the nipple drinker is that when the pig drinks water, the ejector pin is lifted, and the water flows out from the gap between the shell and the valve core to the mouth of the pig; after the pig looses the mouth, the back spring is closely connected, and the water stops flowing out.
When installing a nipple drinker, it should be 45 to 75 degrees from the ground, the height from the ground is 25 to 30 cm for piglets, 50 to 60 cm for growing pigs (3 to 6 months old), and 75 to 85 cm for adult pigs. Suitable for duckbill drinkers).
Cup pig drinking fountain
The cup-type pig water drinker is a one-piece automatic water drinker mainly composed of a water container (water cup), and is commonly used in the form of a float type, a spring valve type and a water pressure valve stem type.
The float type drinking fountains are mostly double cup type, and the float chamber and the control mechanism are placed between the two cups. Usually, a two-cup float drinker is fixedly mounted on the fence between the two pig pens for sharing between the two pigs. The float type drinking fountain is composed of a casing, a float valve mechanism, a float chamber cover, a connecting pipe and the like.
The working principle of the cup-type pig drinker is that when the pig drinks water, the float is pushed to deflect the valve core, and the water flows into the cup for pig drinking; when the pig mouth is left, the valve stem is reset by the spring force of the return spring to stop the water supply. The float has a function of restricting the water level. It rises as the water level rises. When the water rises to a certain height, the pig's mouth will not touch the float. After the valve is reset, the water supply is stopped, and the water is prevented from flowing excessively out of the spring valve type drinker. It is usually cast or stamped from steel. The cup is sold with a cup lid. When the pig drinks water, use the mouth to move the pressure plate to open the spring valve, and the water will flow into the drinking cup. When the mouth leaves the pressure plate, the valve stem is reset to stop the water supply. The water pressure valve stem type drinking fountain is a cup type pig drinking fountain which controls the water by the self-weight and water pressure of the water valve. When the pig drinks water, the pressure plate is pressed by the mouth to make the valve stem deflect, and the water is along the valve stem and the valve. The gap between the seats flows into the drinking water cup, the drinking water is finished, the valve plate naturally hangs down, and the valve stem returns to a normal state.
Adult pigs drink 3-5 times of their feed intake, and piglets drink 1/5 to 1/4 of their body weight. There are two ways to supply water to pigs with regular water supply and regular water supply. Regular water supply is to put water directly into the feeding tank before feeding. The disadvantage is that pigs can't drink the required amount of water at any time, and they are easy to get sick. Regular water supply is the use of pig water dispensers to ensure that pigs drink the required amount of water at any time.
