How big is a circulating pump for 400 kg of water in a fish tank? 5

Oxytocin has the effect of stimulating the smooth muscles of the uterus and causing the contraction of the uterus to promote labor. When sows due to the low content of oxytocin in the body, weak uterine contractions cause dystocia, oxytocin can be used to induce labor, but if used improperly, not only can not play its due role, but also may have great adverse reactions. Usually, when the farrowing process of sows is slow, some breeders or beginner veterinarians, in order to give birth quickly, like to use "oxytocin" (oxytocin) to induce labor.

What is emphasized here is that the use of oxytocin has certain indications and cannot be abused or overdosed. If it is not used properly, it will not only fail to induce labor, but will cause the fetus to suffocate and die, and the sow uterus will rupture and die, causing unnecessary losses. There are many reasons why pigs are born slowly:

There is a large piglet in the birth canal and the pelvic cavity is relatively narrow (especially for primiparous sows or overweight or foreign breeds with double muscles and rumps); At the same time, two pigs were born, blocked at the crossing; Fetal malposition; has been farrowing for a long time, the sow is weak, the uterus is weak; The temperature in the delivery room is too high or the coal stove in winter causes insufficient oxygen, too high carbon dioxide, excessive ammonia in the house, etc. If there is a problem of slow labor, it is more harmful than good to inject oxytocin indiscriminately without careful analysis and birth canal examination. In mild cases, it will cause the fetus to be separated from the placenta prematurely, or the umbilical cord will be broken before delivery, so that the pigs will lose oxygen **, and the fetus will suffocate to death; In severe cases, if the pelvis is narrow, the fetus is too large, and the fetus is not in the correct position (transverse position), the sow will cause the uterus to rupture.

Oxytocin can be used to induce labor in the following cases: after the birth of 1 or 2 pigs, it is estimated that the size of the sow pelvis is normal, the fetal size is moderate, the fetal position is normal, and delivery from the birth canal is no problem, but the uterine contraction is weak, and the sow has been working hard for a long time and cannot produce pigs (with an interval of more than 45 minutes) can consider the use of oxytocin to enhance the contractility of the uterus to promote the delivery of the fetus; In the case of assisted delivery, the pigs that have entered the birth canal have been removed, and it is estimated that there are still pigs that can be used when the uterine horns have not come down; If the afterbirth is not lower, the birthing can be discharged within 1 hour and 3 hours, if it is still not discharged after 3 hours, it is called the afterbirth, oxytocin can be injected, and the injection can be repeated once after two hours.

400 kg of water needs to be as big as oxygen tired.

The 1000 flow pump is suitable for a fish tank with a capacity of 200 liters of water, which is about a fish tank with a length, width and height of 80*45*60 or 100*40*50, that is, a fish tank with a length of about 80-100.

A water pump is a machine that transports or pressurizes a liquid. It transmits the mechanical energy or other external energy of the prime mover to the liquid, so that the liquid energy increases, and is mainly used to transport liquids including water, oil, acid and alkali, emulsion, suspension emulsion and liquid metal.

It can also convey liquids, gaseous mixtures and liquids containing suspended solids. The technical parameters of pump performance include flow, suction lift, head, shaft power, water power, efficiency, etc.; According to different working principles, it can be divided into volumetric water pumps, vane pumps and other types. Positive displacement pumps use changes in the volume of their studios to transfer energy; Vane pumps use the interaction between rotary vanes and water to transfer energy, and there are types of centrifugal pumps, axial flow pumps and mixed-flow pumps.

Summary. The cylinder block has a total of 168 litres of water, using an inverter water pump, with 5 boiling water pumps and a flow rate of 2,000 litres per hour.

The cylinder block has a total of 168 litres of water, using an inverter water pump, with 5 boiling water pumps and a flow rate of 2,000 litres per hour.

The water pump is adapted to the flow rate of 3 times or 5 times of the water capacity, generally 5 times is more appropriate, the formula: 240 * 3 = 720 or 240 * 5 = 1200.

3000L flow pump.

40 cylinders choose 3000L flow pumps, make waves choose a basic model, the shape is smaller, otherwise it will be strange to put it in a small cylinder. The eggs are generally selected to be the largest that can be put down, and the normal ones are placed separately in the bottom tank or in the filter tank for filtration.

Fish tank water turbidity solution:

If it is ruled out that the ornamental fish do not have any diseases, the main reason for the turbidity of the water quality in our fish tank is that the physical filtration effect is not ideal, why it is not ideal, the reason is that the fish food is fed too much, resulting in too much organic matter in the fish tank, and a large number of heterotrophic bacteria outbreak, so that the water quality is not controlled. Therefore, we should give ornamental fish a day of fasting, which can greatly reduce the excessive organic matter in the fish tank.

We must remember to exchange for the same amount of water as the same temperature as the trapped isothermal, each time the water is not more than a quarter or a fifth of the water in the fish tank, so that through three days, we will replace about three-quarters of the old water in the fish tank, and will not lead the overall situation to cause turbulence in the water quality in the fish tank, and there is no harm to the imitation of the remaining ornamental fish. <>

Summary. The principle of pump selection is that the amount of water pumped per hour is at least 2 times the volume of the entire water body (the smaller the tank, the larger the multiple is more than 4 times, and the medium tank or fish pond can be set to more than the double). In other words, a one-ton pool should choose a pump that pumps more than 2,000 liters of water per hour.

As for the model and brand, there are many options for this type of pump, and it would be good to take a more cost-effective one. When the deterioration of the pool water is serious, it is advisable to adopt water replacement measures to maintain good water quality conditions.

When the deterioration of the pool water is more serious, it is advisable to adopt water exchange measures to maintain the water quality disturbance conditions prepared by conscience.

4 tons corresponds to a pump of more than 8,000 litres per hour.

You can just follow this and make your choice

Summary. If you use 4 tons of water, you can use Fubang's model, with a power of 50W energy-saving and silent, circulating filtration, and oxygenation as a whole, which effectively solves the problem of water quality in fish ponds.

If you use 4 tons of water, you can use the model of Fubang, the power omen bucket rate is 50w energy-saving and silent, and the Huizu ring is filtered and oxygenated as a whole, which effectively solves the water quality problem of the fish pond.

Outdoor fish ponds generally need to be recycled several times per hour.

At least 3 times. But what you recommended just now can't be cycled three times.

If it is not an automatic cycle, because the cleanliness of the fish pond water is related to various factors such as feeding density, feeding amount, filter material situation, etc., the specific value of the finger beat cannot be determined, and then you can only rely on your own feelings to determine the time of the filtration cycle.

What does auto-loop mean.

FB5000 is not an automatic cycle.

4 tons of water can only be recycled more than once.

Be. This one will do.

Is it better to have as many cycles as possible?

Not really. The number of cycles is set according to the size of the pool, and it is reasonable.

For a 4-ton pool, FB5000 is fine.
