The 3- ton fire sprinkler is a relatively large-scale machine. To prevent damage to the machine and increase the efficiency of the machine, we must use it after understanding the use of the machine, so that we can achieve a multiplier effect. So what are the precautions for using a 3-ton fire engine? Â Â When the fire hydrant in the fire sprinkler is used to fill water, the fire hydrant supply pressure must meet the demand of the fire engine. It is best to select natural water sources during the selection of water sources, but when using river ditch or pond water sources, it is necessary to pay attention to putting all the suction pipes inside the fire sprinkler into the water while avoiding suction pipes to inhale stones or debris. Wait, otherwise it will cause damage to the equipment. Generally, a suction device is installed inside the suction pipe. During the water absorption, the filter device should not be taken out. Water can not be selected where the water level is shallow, and water can not enter the suction pipe during water absorption so as to avoid interruption of water absorption. Â Â Â Fire sprinklers are relatively low in the number of devices for rinsing water. To prevent equipment damage, be careful to avoid obstacles during operation. When using a fire sprinkler to eliminate a fire, after entering the fire site, it must be in accordance with the requirements of the command to enter the designated position to park the vehicle, so as to be able to flexibly attack the fire. After entering the fire, the engine must always be in operation. In order to prevent combatants from harming due to the reaction force of the water gun, the fire sprinkler must gradually increase the water pressure when it starts to supply water. Â Â Â Because fire sprinklers have the function of fire fighting, they need to be filled with liquid at any time, but the low temperature in winter is relatively low, because there is water and sometimes the temperature of the equipment will be even below zero. At this time, we must pay attention to shutting off the water tank and fire. Pump ball valve. At the same time also need to open the fire pump, power take-off, fire cannons and fire hose discharge valve, remove the residual moisture inside the pipe, so as not to freeze the device. Double-Cone Rotary Vacuum Dryer
As a professional drying equipment manufacturer, we provide more than hundred sets of equipment for our users. The heating media such as high temperature heat transfer oil, middle temperature steam and low temperature hot water are available for our products. When drying viscous materials, we can design the special [copying" mechanism or set balls in the tank for you.
Applications:
It is suitable for concentration, mixing and drying of powder, granular and fibrous materials in such industries as chemical industry, medicine, food, etc., and materials that require low temperature drying(such as biochemical products), and is more suitable for drying of materials that are easy to oxidize, volatize, heat sensitive materials, irritant and poisonous materials, and materials in which breaking of crystals is not allowed.
Principle
• After the heat source(such as hot water, low pressure steam or heat transfer oil) is connected to the closed jacket, the heat is transferred from the inner shell to the materials to be dried.
• Driven by the power, the tank makes slow rotation and the materials in the tank are continuously mixed so as to realize the purpose of drying.
• When the materials are under vacuum, the steam pressure reduces to make the moisture(solvent) on material surtaces reach the saturation status and evaporate, and discharged and recovered timely from the vacuum pump. The moisture(solvent) inside the materials is penetrated, evaporated and discharged towards the surfaces. The three processes are carried out continuously, so that the materials are dried within a very short time.
Features
• During oil heating, automatic constant temperature control is adopted to dry biochemical products and mineral raw materials.
Temperatures vary within the range of 20-160℃.
• The heat efficiency is 2 times higher than that of common ovens.
• Indirect heating will cause no pollution to the materials, conforming to GMP requirements. The equipment is simple to repair and operate and easy to clean.
