A swimming pool, swimming bath, wading pool, or paddling pool is a container filled with water to enable swimming or other leisure activities. Pools can be sunk into the ground or built above ground (as a freestanding construction or as part of a building or other larger structure). In-ground pools are most commonly constructed from materials such as concrete, natural stone, metal, plastic or fiberglass, and can be of a custom size and shape or built to a standardised size.
Spa pools are pools filled with hot water, used for relaxation or hydrotherapy, and are common in homes, hotels, clubs and massage parlors. Special swimming pools are also used for diving and other water sports, as well as for the training of lifeguards and athletes.
From spa industrial fashion trend, the freestanding swimming pool with hydro therapy, made with acrylic and fiberglass is more and more popular, easy for customers to get and install, it's called swim spa. This type swim spa are mostly installed with powerful whirlpool pump to drive swim jet to produce strong water flow against swimmer, offer swimming exercise. Due to the water flow out of swim jets, it is still be influenced by the resistance from jet and hose, jet type swim spa may be enough for common home use, but may not be enough powerful for an athletes or other strong swimmer.
Today we, J&J, would like to present our PRO series of swim spas in the market, to meet the demand of athletes and professional swimmer fully. The Pro swim spa is equipped with 2.8Kw to 5.6Kw axial-flow pump, with adjustable nine speeds. The axial-flow pump, or AFP, is a type of pump that essentially consists of a propeller (an axial impeller) in the swim spa. The propeller can be driven directly by a sealed variable frequency electric motor mounted to a circle hydroecium to produce powerful water flow, to offer endless swimming sport in a limited space. How powerful it is? From our testing, a 2.8Kw PRO swim spa runs at 5-6 speeds is enough for an adult woman, and 6-7 speed is enough for an adult man, and the 8-9 speeds are leaving for challengers.
In order to ensure the normal circulation of the water of the whole pool to flow, and the flow water in the pool can be calm with potency dimension, we according to size of the swim pool deploy different quantity of backwater port, and then install the return grid around the pool, let the water more steady, at the same time, let the swimmers swim forward all the time as if they are swimming in the sea without the dangerous of vortex or surge.
Water Recovery Equipment
The unique aftermath can weaken training strength rapidly with the water calm.
According to the requirements of different power and current speeds,The training also deplolies water recovery apparatus to assure the using of water enough,which it made the water gentle and stable.Satisfied with the level demands from swim beginner to Olympic swimmers.
Laminar and turbulent flows
Laminar and turbulent flows
Turbulence is a kind of fluid flow state. When the velocity is very small, the layer of fluid flow and mix each other, known as the laminar flows, when the velocity increases to a large, streamline no longer clearly discernible, there are many small vortex in the flow field, laminar flow are destroyed, not only between adjacent flow layer sliding, and mixing, forming turbulent flows.
Laminar flow features
Mixed liquid mutually between each layer, the liquid particle trajectory is straight line or a smooth curve of the rules. Our swim spa can show you the best interpretation.
Within the limited space to the stillness of the directional layer type water flow, make the swimmer reverse laminar winding and take in everything in a glance of your strokes .Using propeller technology frequency conversion to promote the flow of water, and can freely adjust the flow dynamics by yourself, let you feel is no marginal in real space to swim! There are some big outlets in the pool and installed in the large back to the spa, ensure that the swim spa water flow of normal circulation flow, and can make the water in the pool is smooth with dynamics, as if in the absence of marginal in the swimming pool to swim in deep waters has been moving forward, also no worry will meet any of the spiral or dangerous waves.
Professional propeller pump produces broad, deep, powerful current, no air, no noise.
Diversion device inside water outlet can produce laminar flow to create ideal swimming environment.
Produces more water flow with less energy.
Maximum flow velocity: 1.8m~2.3m / sec. it suit athletes for training.
Water and electricity separated,no electric leakage.
Various of swim pool
We choose 2.8kw to 5.6kw Pro swim pump for swim pool upon their size and design,the pump along with propeller can bring out bigger,faster,smooth water flow,and water flow can be switched for different speed through frequency converter to cater for different user. We now have 4 type of swim pool:Entry level,Standard level,Entertainment level and Professional level,they suit for different people for different desire.
Frequency conversion technique
Frequency conversion technique:
This technology can reduce consumption of energy and enhance enjoyment of exercise.
Double control panels:
Two control panels control swimming pool zone and spa massage zone separately, which make the operation easier, improve the efficiency and extend the lifetime.
9 speeds can be switched:
Different speeds are design for different people.
Speed 1 and Speed 2 are suitable for young and elderly swimmers, or for underwater walking rehabilitation.
Speed 3 and Speed 4 are for swimming beginners and female swimmers.
Speed 5 to 7 are mainly fit for swimming amateurs.
Speed 8 and Speed 9 can meet the needs of professional athletes.
Swimming and rehabilitation training
Swimming and rehabilitation training
With antiskid massage panel in the bottom of our swimming pool, water outlet and water return ostium ensure the water flow's balance. At the same time, they make the water flow attached strength, which is suitable for different ages people, especially for the old and weak, the injured to wall or do some other activities in the swim spa for physical restoration. Two of our arms can drive the water, swing and so on after getting into swim spa, which let our muscle gaining effective exercise. Finally, they have a good consequence for enhancing our health.
During walking in the water, bigger resistance is needed to be conquered. Hence our muscle and visceral organ will enjoy enough exercise. Generally, people walk in the water deep to waist, they walk 1 step/ second and walk 3 to 5 minutes under that frequency, their heart rate will reach 70% to 85% of max heart rate, and their respiratory rate is over twice respiratory rates when they are without doing any activities，knee-join burden is tiny due to water buoyancy, the muscle around the knee-joint and muscle tendon will get enough extension. And limb injured are rare, thus many water activities become one of popular rehabilitation methods among the mild injured. propeller technology make water flow coming into being and the water flow product Von Karman vortices, which Shake our body fat and let our brain wave area steady. AS the same time, they stabilize neurotransmitter for attaining a good therapy effect and accelerating the rehabilitation.
Swimming and athletics
Swimming and athletics
Athletic swimming is a kind of sport based on speeds, which need high technology to reduce resistance to improve swimming impetus, and take fully advantage of our energy for sport. High elbow flexion arm driving water is the one of convincing example which can explain swimming technology important feature.
They display shoulder joint relatively fixe when we swim and the position of shoulder joint more higher.
Compared to other way of driving water, high elbow flexion arm driving way can easily improve the swimming speed. Driving water frequency and their distance are regarded as one of criterion in the swimming technology. They are three important elements for swimming athlete.
Our newest swim pool adopts laminar flow technology, you will clearly observe athlete's swimming posture which is good for coach's observation and guiding for the athlete.
With adjustable control panel, coach can directly adjust athletes' swimming post, and find athletes' most appropriated connection of driving water frequency and distance, which can effectively improve athletes' score.
Maximum water flow of our new swimming pool reach to 2.3meter/second, which have attained Olympic athlete's training water flow speed.
