The installation and operation of the coal powder sampler and mobile coal powder sampler of Lianyungang Lingdong Electromechanical Equipment Co., Ltd. drill holes on the flue, extend the sampling tube into the flue, and make the sampling head face the direction of the incoming smoke flow.

The purpose and function of the fly ash sampler produced by Lianyungang Lingdong Electromechanical Equipment Co., Ltd. is that the carbon content of boiler fly ash is an important indicator reflecting the combustion rate of coal-fired boilers in thermal power plants.

The oil supply and lubrication oil injectors are completely identical in structure, mainly composed of orifice nozzles, diffusion tubes, sleeves, filters, etc.

The function of the oil injector of Lianyungang Lingdong Electromechanical Equipment Co., Ltd. is to use a small amount of lubricating oil as power, suck in a large amount of oil, and supply lubricating system and main oil pump with oil at a certain pressure.

A steam injector is a device that is powered by steam and is needed in modern engineering. It does not require electricity, has no moving or rotating parts, is simple in system, and works reliably, so it is used.

The oil injector is composed of a nozzle, a filter screen, an expansion pipe, and an inlet pipe. In addition to supplying the inlet oil of the centrifugal main oil pump, it also supplies lubricating oil system and sealing oil system oil.

The structure and working principle of the fixed coal powder sampler produced by Lianyungang Lingdong Electromechanical Equipment Co., Ltd. are mainly used for regular coal powder sampling on the secondary air coal powder pipe in the positive pressure direct blowing coal powder system.

The portable constant velocity fly ash sampler produced by Lianyungang Lingdong Electromechanical Equipment Co., Ltd., also known as the fly ash constant velocity sampler or the swirling fly ash constant velocity sampler,

The working status of the oil injector and main oil pump, the analysis of the reasons for the drop in the inlet oil pressure test of the main oil pump of a 200MW steam turbine, and the composition of the oil supply system of the 200MW steam turbine generally adopt a centrifugal main oil pump oil supply system with dual injectors.

The use of carbon steel material in coal powder samplers has caused many problems, and some manufacturers still encounter these problems when using coal powder samplers. So it is recommended to use stainless steel material at least ---.
