Working principle of fire pump

以它全密封、无泄漏、耐腐蚀之特点,广泛用于环保、水处理、消防等部门用来抽送各类液体,是创建无泄漏、无污染文明车间、文明工厂的理想用泵用与消防系统的泵类型都差不多的,只是扬程和流量有不同。 As the name implies, fire pumps are imported from overseas. They are classified into different types according to different classification methods. With its characteristics of full sealing, no leakage and corrosion resistance, they are widely used in environmental protection, water treatment, fire protection and other departments. To pump all kinds of liquids, it is the ideal pump for creating a leak-free and pollution-free civilized workshop and civilized factory. The pumps are similar to the pumps in the fire protection system, but the head and flow are different.The selection basis of fire pump should be considered from five aspects according to the process flow and water supply and drainage requirements .

GB6245-2006<<消防泵>>标准来生产各种消防泵,经消防装备质量监督检测中心检测,各项性能指标均达到或超过标准 ,并且获得消防产品3CF认证证书Shanghai Xizhiquan Pump Valve Co., Ltd. produces various fire pumps in strict accordance with the newly issued GB6245-2006 << Fire Pumps >> standard according to market requirements . After testing by the Fire Equipment Quality Supervision and Testing Center, all performance indicators have reached or exceeded standards And obtained 3CF certification for fire products . ( www.cccf.com.cn )公布 And announced on China Fire Network ( www.cccf.com.cn )

: 泵体铸铁并涂喷大红漆 , 配置有不锈钢叶轮 , 进水口 , 出水口 , 水泥台座 , 直管 , 联接板 , 隔振器 , 隔振热等部件 In structure : the pump body is cast iron and painted with red paint , equipped with stainless steel impeller , water inlet , water outlet , cement pedestal , straight pipe , connecting plate , vibration isolator , heat insulation and other components

: 叶轮安装在泵壳内,并紧固在泵轴 3上,泵轴由电机直接带动。 In principle : the impeller is installed in the pump casing and fastened to the pump shaft 3. The pump shaft is directly driven by the motor. A liquid suction 4 is connected to the suction pipe 5 in the center of the pump casing. The liquid enters the pump through the bottom valve 6 and the suction pipe. The liquid discharge port 8 on the pump casing is connected to a discharge pipe 9.
Before the pump is started, the pump casing is filled with the liquid being transported. After the pump is started, the impeller is driven to rotate at high speed by the shaft, and the liquid between the blades must also rotate. Under the action of centrifugal force, the liquid is thrown from the center of the impeller to the outer edge and gains energy, leaving the outer edge of the impeller at high speed and entering the volute pump casing. In the volute, the liquid decelerates due to the gradual expansion of the flow channel, and converts part of the kinetic energy into static pressure energy, and finally flows into the discharge pipe at a higher pressure and is sent to the required place. When the liquid flows from the center of the impeller to the outer edge, a certain vacuum is formed in the center of the impeller. Because the pressure above the liquid level in the tank is greater than the pressure at the pump inlet, the liquid is continuously pressed into the impeller. It can be seen that as long as the impeller rotates continuously, the liquid will be continuously sucked in and discharged.
