The oil injectors produced by Lianyungang Lingdong Electromechanical Equipment Co., Ltd. generally consist of nozzle filters, expansion pipes, inlet pipes, etc., and are installed on the main oil pump. When the pressure oil is sprayed out at high speed through the nozzle, a vacuum is formed at the nozzle. By utilizing the suction effect of the free jet, the oil in the tank is brought into the diffusion tube for deceleration and pressure increase, and then discharged at a certain pressure. Enable the main oil pump to have a certain pressure and improve the reliability of its operation.

The functions of lubrication oil tank injector 1 # and injector 2 # for steam turbines:

-The general unit is equipped with two oil injectors, which are divided into an oil injector and a second oil injector, also known as an oil injector. The second oil injector is installed below the liquid level in the lubricating oil tank, and when the unit is put into operation at or near the rated speed. The oil injector consists of a nozzle, a mixing chamber, a diffusion tube, etc. After the pressure oil from the main oil pump passes through the nozzle, the oil velocity increases and forms a low-pressure zone in the chamber. The oil in the tank is pumped into the injector chamber, and then it is carried by a high-speed oil belt into the diffuser throat. The velocity decreases in the diffuser and is converted into pressure energy. Then, through an oil cooler, it is sent through a pipe to the bearing manifold and the main oil pump suction port. Diffusion - equipped with a rocker check valve at the back to prevent oil from flowing back from the system. A check plate is installed on the surface of the oil tank in the chamber to prevent backflow into the oil tank during the operation of the bearing oil pump. To prevent foreign objects from entering the oil injector, a detachable perforated steel plate filter screen is installed on the oil suction side of the injector. The oil injector is one of the essential equipment in the lubricating oil system of the steam turbine generator set. In the lubricating oil system of the steam turbine generator set, the oil injector equipment can be divided into oil supply injectors and lubricating oil supply injectors according to its working purpose. Its working medium is L-TSA 32 turbine oil, with a working oil temperature of 45 ℃~65 ℃. When the unit reaches or approaches the rated speed, it is put into operation.

1. Fuel injector:

During normal operation of the unit, sufficient oil is provided to the main oil pump, with a portion of the pressure oil at the outlet of the main oil pump as its power oil.

2. Lubricating oil injector:

During the normal operation of the unit, lubricating oil is provided to the bearings of the steam turbine generator set, and its power oil is still part of the outlet of the main oil pump.

The installation of oil injectors requires attention to the following two aspects:

3. Assembly and installation:

The installation of the oil injector and its impact on energy are different. When installing the nozzle of the oil injector and lubricating oil injector, the nozzle bracket and inlet pipe flange must be tightened to ensure high-pressure oil leakage. The flatness and smoothness of all adhesive surfaces should be -.

4. Maintenance and upkeep:

When the oil injector is transported to the site after leaving the factory, if it is not immediately put into use, it needs to be repainted and sealed for protection. If it cannot be installed or filled with oil within two months of arriving at the site, it should be installed. The oil injector must be disassembled and inspected to remove rust and dirt. During the overhaul of the unit, the oil injector needs to be disassembled and inspected, and the nozzle should not be inspected. The surface roughness of the spray hole should reach the surface roughness (arithmetic mean of the contour deviation within the sampling length) R α The upper limit value is 3.2 microns. If there are any scratches or indentations, they need to be replaced.

The purpose of fly ash sampler

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.

Installation and working engineering of coal powder sampler

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.

Tube replacement of tubular oil cooler

When purchasing a column type oil cooler for tube and core replacement, The cooling area should be informed. The cooling forms are divided into LY type light tube (for use) and LYC type fin type. Stainless steel tubes are generally selected for heat exchange and cooling, and purple copper, brass, and titanium tubes can also be selected as heat exchange components according to user needs.

Replacing The tube of The shaft seal heater

Manufacturer of shaft seal heaters, also undertaking pipe replacement and renovation of shaft seal heaters, replacing copper pipes, stainless steel pipes, boiler pipes, etc. According to customer needs, The replacement, repair, installation, and restoration of The relevant shaft seal heater pipes must be carried out. The original equipment must be sent to our company for pipe bundle replacement.

oil cooler tube replacement and maintenance

We are a manufacturer of oil cooler tube replacement and maintenance. We undertake various types of tube coolers, condensers, oil coolers, chillers, air coolers, condensers, and oTher heat exchange and cooling tube replacement and renovation projects. Change The material of The pipes, such as copper pipes, stainless steel pipes, titanium pipes, etc.

Surge tank

The function of The pressure equalization box: Its main function is to collect, distribute, and balance steam pressure, which is set up for steam seals. 1. Balance The expansion and pressure reduction of The steam entering and exiting The casing, and adjust The pressure and temperature of The steam required for The start-up shaft seal.

Replacing pipes for marine oil coolers

Welded steel pipes (also known as slotted pipes and welded pipes) are mainly used for auxiliary machinery in industries such as Thermal power generation, chemical industry, and steel, such as condenser and heater pipe replacement, tubular marine oil cooler pipe replacement, oil-water cooler pipe replacement, tubular marine oil cooler pipe replacement, and Le tube cooler pipe replacement.

Assembly and installation of oil injectors

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

drain flash tank

A drainage expansion vessel is a type of vessel that expands and depressurizes The drainage of The pressure drainage pipeline, separates steam and drainage, and introduces steam into a heat exchanger or deaerator. The drainage expansion vessel consists of two 16m rectangular containers, with The oTher mainly accepting high-pressure heater emergency drainage and deaerator overflow drainage.

Steam seal heater tube replacement and renovation

The steam seal heater adopts a horizontal U-shaped surface heat exchanger for pipe replacement and transformation. The pipe material is stainless steel pipe, and in addition to expansion joint, The pipe also needs to be sealed and welded with The pipe plate; HSn-70-1 tin brass is also used and fixed on The tube plate by expanding The tube.
