Cheap PriceList for TU-1F93 thermal wax actuator for thermostatic automatic water drain valve for Croatia Factories
Cheap PriceList for TU-1F93 thermal wax actuator for thermostatic automatic water drain valve for Croatia Factories Detail:
1. Operation Principle
The Thermostatic Wax that has been sealed in shell body induces expansion by a given temperature, and inner rubber seal part drives its handspike to move under expansion pressure to realize a transition from thermal energy into mechanical energy. The Thermostatic Wax brings an upward movement to its handspike, and automatic control of various function are realized by use of upward movement of handspike. The return of handspike is accomplished by negative load in a given returned temperature.
(1)Small body size, occupied limited space, and its size and structure may be designed in according to the location where needs to work.
(2)Temperature control is reliable and nicety
(3)No shaking and tranquilization in working condition.
(4)The element doesn’t need special maintenance.
(5)Working life is long.
3.Main Technical Parameters
(1)Handspike’s height may be confirmed by drawing and technical parameters
(2)Handspike movement is relatives to the temperature range of the element, and the effective distance range is from 1.5mm to 20 mm.
(3)Temperature control range of thermal wax actuator is between –20 ~ 230℃.
(4)Lag phenomenon is generally 1 ~ 2℃. Friction of each component part and lag of the component part temperature cause a lag phenomenon. Because there is a difference between up and down curve of traveling distance.
(5)Loading force of thermal wax actuator is difference, it depends on its’ shell size.

Gardens by the Bay is a park of 101 acres of surface hardened (about 250 acres or 1.01 km ² ) located in the center of Singapore, adjacent to the artificial lake Marina Reservoir. The park consists of three parks that overlook the water Bay South Garden, Garden Bay East and Bay Central Garden. The Gardens by the Bay 18 artificial, so-called “super tree” rise, they are 25 to 50 feet high, eleven of them solar- equipped. Some trees in greenhouses ventilation channel function, or rain water collected. Two super tree skywalk bridge called up the subject. Vines cling to the trees.
In the garden, two greenhouses all over the world gathered plants, a total of 220,000 copies can be viewed in a variety of species for the ideal temperature and humidity controls the greenhouse automatic manner. Singapore a leading global city of the 21st century, the 101-acre park includes a futuristic bunch of huge metal trees (Super Tree grove ‘), an architecturally landscaped park two large greenhouses (biomes). It is adjacent to Singapore Botanic Gardens, National Orchid Garden, the third Singapore Botanic Gardens.
In January 2006 an international master plan design competition was held. It attracted more than 70 entries submitted by 170 companies from more than 24 countries, including 35 from Singapore. In September 2006, the British firms Grant Associates and Gustafson Porter received the award, each part of the Gardens. In November 2007 began the development. In October 2011, the Gardens by the Bay was officially opened to the public.
The concept of Gardens by the Bay is based on the principles of environmental sustainability. There is a lot of effort into the design of sustainable energy and water cycles. Gardens by the Bay consists of a freely accessible very modern park and a number of facilities for which an entrance fee. In the eye-catching addition to the metal trees, two glasses biomes.
The metal trees – super trees – are tree-like structures that dominate the landscape of the Gardens with altitudes ranging between 25 meters and 50 meters. These are vertical gardens with a multitude of functions such as providing shade and act as environmental engines for the gardens are to perform. The super trees are home to unique and exotic ferns, vines, orchids and an extensive collection of bromeliads, such as Tillandsia. They are also equipped with environmentally friendly technologies that mimic ecological function of trees: Photosynthesis – solar cells that generate energy for some of the functions of the Super Trees, such as lighting; Absorb rainwater – and collect rainwater for use in irrigation and fountain displays, the Super Trees also serve air intake and exhaust functions as part of the cooling conservatories.
One biome gives a picture of the cooling-dry climate of the Mediterranean and semi-arid subtropical regions. The other gives an impression of cool-humid climate of a tropical montane area. They accommodate both a diverse collection of plants that is not often seen in the humid tropics where Singapore is located. Use is made of many different levels and very modern architecture.
The greenhouses are equipped with renewable energy efficient cooling solutions and achieve at least 30% energy savings compared to conventional cooling techniques. The two greenhouses are equipped with specially selected glass that best gives light to the plants, but the radiant heat largely holds. The roof is equipped with folding sails that automatically open to give to the plants if it gets too hot. Only the lower parts of the greenhouses are cooled. This is achieved by means of thermal stratification. Pumped groundwater cooling pipes in the floor slabs. Warm air rises and is discharged at a high level. In order to reduce the amount of energy that is required in the cooling process, the air in the greenhouse with the Mediterranean climate dehumidified before it is cooled. The drying agent used for that purpose, is recycled by means of the waste heat from the combustion of the biomass. Electricity for cooling is generated on the premises. At the same time, waste heat absorbed by which the desiccant is regenerated. It uses a special steam turbine fed by horticultural waste from gardens and other parks in Singapore.

Harold Beck & Sons, Inc. exhibited with MagnaDrive at the WEFTEC 2011 tradeshow. MagnaDrive Adjustable Speed Drive (ASD) couplings transmit torque from a motor to a load across an air gap. There is no physical connection between the two sides and the transmission of torque is done so using rare-earth magnets. Beck electric actuators are connected to a lever arm on the ASD which modulates the air gap spacing through a 4-20 mA demand signal, in turn, controlling the speed of the transferred load.
