In order to meet the needs of various emergency equipment on the construction site, Shaanxi Construction Machinery Co., Ltd. recently produced a F15Z multi-function lighting vehicle, which provided great convenience for construction.
The F15Z multi-function lighting car is modified on the basis of the dump truck. It is equipped with a 10kW generator, which is fully functional, mobile and easy to use. The lighting fixture is made of fully enclosed high-pressure cast aluminum casing, which has high protection level, light and beautiful shape and easy installation. The matching light source is made of 400×4 illuminated metal halide lamp, which has large luminous flux and high temperature resistance. The pole is designed to be 3-section telescopic, and the height of the lighting can be adjusted at any time according to the needs of the site. The equipped mobile power supply can meet the needs of many small electrical equipment such as cutting machines, electric drills and electric welding machines in the field construction site.
A ballcock (also balltap or float valve) is a mechanism or machine for filling water tanks, such as those found in flush toilets, while avoiding overflow and (in the event of low water pressure) backflow. The modern ballcock was invented by José Antonio de Alzate y RamÃrez, a Mexican priest and scientist, who described the device in 1790 in the Gaceta de Literatura Méxicana.[1] It consists of a valve connected to a hollow sealed float by means of a lever, mounted near the top of the tank. The float is often ball-shaped, hence the name ballcock. The valve is connected to the incoming water supply, and is opened and closed by the lever which has the float mounted on the end. When the water level rises, the float rises with it; once it rises to a pre-set level, the mechanism forces the lever to close the valve and shut off the water flow. This is an example of negative feedback and of proportional control.
