The basic principle of lubricating oil system injectors

Basic principle of lubricating oil system - oil injector:

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 working principle of the oil injector is to use a small amount of lubricating oil as power, suck in a large amount of oil, and supply oil to the lubrication system and main oil pump at a certain pressure. The nozzle of the oil injector is connected to the outlet of the main oil pump that provides power oil. High pressure oil leaves the nozzle at a high speed and enters the expansion pipe, forming a negative pressure at the nozzle mouth. Under the action of the negative pressure, the oil in the oil tank enters the joint chamber of the injector through the filter screen, and together with the ejected injection oil, enters the expansion pipe. The kinetic energy of the oil in the expansion pipe is converted into pressure energy.

Repair of oil injector:

1. Remove the fastening bolts, remove the nozzle, oil chamber, and expansion pipe of the oil inlet pipe. 2. Clean and inspect the above components. The nozzle and diffusion pipe should be smooth, with no punctures or severe rust, and there should be no debris in the oil chamber. 3. Disassemble and measure the distance between the nozzle and the expansion tube, the diameter of the nozzle mouth, and the diameter of the diffusion tube throat, and make a record to maintain the original dimensions above. 4. After reinstallation, the bolts should be tightened reliably.

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.

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.

The function of an oil injector is to use a small amount of lubricating oil as power

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.

oiler oil injector

The lubrication oil system's oil injector mainly consists of a containerized oil tank, main oil pump, oil supply injector 1 # (also known as oil injector), oil supply injector 2 # (also known as secondary injector), AC lubrication oil pump, etc. Also known as oiler - oiler, second oiler, installed below The liquid level in The lubrication oil tank. The oil injector consists of a nozzle, a mixing chamber, a diffusion tube, etc.

The principle of steam jet pump and steam injector

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.
