Test Weight Water Bags are also called water weights, load test water bags, lifting water bags, etc. A weighing water bag is mainly used in ship cranes, shipyard cranes, port cranes, offshore platform cranes, gantry cranes, driving cranes, davits, etc., lifting equipment for load detection. It is more efficient, safer and cheaper to detect than traditional solid weights.
â— High-frequency welding is used to make the DOING Load Testing Water Bags, and its outside is wrapped in high-strength fiber slings.
◠Crane Water Bags are made of high-density composite materials (PVC, TPU) with superior sealing and corrosion resistance. It can be used at -30°C to 70°C, and it will not be unable to use normally due to seasonal changes. The material is reinforced with anti-freezing, anti-oxidation, and anti-ultraviolet properties. It is not affected by seawater, chemicals, agents, oil stains, acid and alkali and aquatic organisms.
â— Water Bags for Weight can be folded during transportation, which greatly reduces space. Simple operation, light weight, small size, economical and practical, and long service life.

Shanghai Haozhuang Instrument Co., Ltd. has developed the LNB brand sealed ultrasonic reactor, which is energy-saving and environmentally friendly, leading the country. Professional manufacturing is more secure and affordable.
Product Description of Ultrasonic Reactor Thermostatic sealed ultrasonic reactor is professionally manufactured by Shanghai Haozhuang Instrument Co., Ltd. It is used for sonochemical reaction, enzymatic reaction, preparation of nano materials, crushing, emulsification, homogenization of animal and plant cells, virus cells, Demulsification, dehydration, separation, extraction, digestion reduction, defoaming, oxidative desulfurization of petroleum, treatment of refractory organic wastewater, degreasing of oily sludge, dehydration of remaining biological sludge, algae removal, algae suppression, sterilization, cleaning Wait. There are two main types of generators used in ultrasonic reactors in the fields of chemistry, chemical engineering, materials engineering, environmental engineering, biochemistry, microbiology, pharmaceutical chemistry, surface chemistry, physics, zoology, etc .:
One is the use of mechanical methods to generate ultrasonic waves, which are pneumatic (air whistle) and liquid (liquid whistle); the other is the use of electromechanical effects to generate ultrasonic waves: there are ultrasonic cleaning machine reactors, acoustic horns immersed in the reaction And cup reactors.
The energy-concentrating acoustic horn is immersed in the ultrasonic reactor by directly immersing the high-power ultrasonic transducer horn into the reaction liquid, and transferring a large amount of energy directly to the reaction medium, effectively converting electrical energy into mechanical energy, which can be changed by changing The amplitude of the ultrasound delivered to the probe controls the amount of ultrasound energy, which is commonly used in laboratory extraction and chemical reaction studies. The advantages of the acoustic horn immersion reactor are that the sound intensity is adjustable, and a higher sound intensity can be obtained. The disadvantage is that the temperature of the reaction liquid is difficult to control, and the surface of the probe is corroded by cavitation, which may cause contamination of the reaction liquid. The constant temperature fully enclosed ultrasonic reactor produced by our company overcomes these shortcomings with its unique proprietary technology, and also solves the problem of sealing the horn and the reactor. Together with various chemical reactor accessories, it is enough to achieve the reaction The separation of the system atmosphere and the condensation and reflux of the vapor phase. The structure of the temperature-controlled fully-enclosed multi-band ultrasonic reactor is also suitable for further construction of a variety of new reactors, such as: ultrasonic internal loop air-lift reactor. Ultrasonic air-lift internal loop reactor has simple structure, low cost and good effect. It has great application potential in gas-liquid two-phase and gas-liquid-solid three-phase reactions. The transducer emits strong ultrasound, and the reactor can also be designed to produce super-focused ultrasound energy. The product is highly extensible and is a versatile and multi-purpose ultrasonic treatment of materials. The instrument can be used as an ultrasonic emulsifying and dispersing device, an ultrasonic homogenizer, an ultrasonic cell pulverizer, an ultrasonic breaker etc.
