What about Bejing Voyage Machinery Parts ？

Are you finding a company which is specializing in machinery parts? Such as, Fuel Injector, Turbocharger, Hydraulic Pump, Cylinder Head. I would like to introduce them as the below.

Fuel Injector

Fuel injector, as the name suggests, is a device used to inject fuel, which judges the injection of fuel according to the signal sent by ECU. The fuel injector has spray characteristics such as atomization particle size, oil mist distribution, oil beam direction, range and diffusion cone angle, and belongs to a finishing instrument.
The fuel injector is an important part of the fuel supply system of diesel engine to realize fuel injection. Its function is to atomize the fuel into fine droplets according to the characteristics of the diesel engine mixture, and inject them into specific parts of the combustion chamber.
Fuel injectors are generally divided into open type and closed type. Closed type fuel injectors are widely used in automotive diesel engines, which are composed of fuel injector body, pressure regulating device, fuel injector and other parts. The fuel injector of the closed injector is a pair of precision coupling parts, which is composed of a needle valve and a needle valve body. Generally, the needle valve is made of high-speed steel with good thermal stability, while the needle valve body is made of high-quality impact resistant alloy steel. After finishing and pairing grinding, their fitting clearance is extremely small, only 0.002 ~ 0.004mm. According to the different structural forms of fuel injector, closed injector can be divided into three forms: Hole Injector, axial needle injector and low inertia injector, which belong to the first two types and are widely used.

Turbocharger

Turbocharger is actually an air compressor, which increases air intake by compressing air. It uses the inertia impulse of the exhaust gas discharged by the engine to drive the turbine in the turbine chamber. The turbine drives the coaxial impeller, which presses the air sent by the air filter pipe to pressurize it into the cylinder. When the engine speed increases, the exhaust gas discharge speed and the turbine speed also increase synchronously, and the impeller compresses more air into the cylinder. With the increase of air pressure and density, more fuel can be burned, and the output power of the engine can be increased by correspondingly increasing the amount of fuel and adjusting the engine speed.
Turbocharger has five main advantages:

1. Increase engine power. With the engine displacement unchanged, the engine can inject more fuel by increasing the intake density, so as to improve the power of the engine. The power and torque of the engine with supercharger should be increased by 20% - 30%. On the contrary, under the same power output requirements, the cylinder diameter of the engine can be reduced, and the volume and weight of the engine can be reduced.
2. Improve engine emissions. By improving the combustion efficiency of the engine, the turbocharger engine can reduce the emission of harmful components such as particulate matter and nitrogen oxides in the engine exhaust gas. It is an indispensable configuration for diesel engines to meet the emission standards above Euro
3. Provide plateau compensation function. In some high altitude areas, the higher the altitude is, the thinner the air is. Engines with turbochargers can overcome the power reduction of engines caused by the thin air in the plateau.
4. Improve fuel economy and reduce fuel consumption. Because the engine with turbocharger has better combustion performance, it can save fuel by 3%-5%.
5. It has high reliability, good matching characteristics and high transient response characteristics.

Hydraulic Pump

The hydraulic pump is the power component of the hydraulic system, which is driven by the engine or motor, sucks oil from the hydraulic oil tank, forms pressure oil and discharges it to the actuator. Hydraulic pumps are divided into gear pumps, plunger pumps, vane pumps and screw pumps according to their structures.
A hydraulic element that provides pressurized liquid for hydraulic transmission, which is a kind of pump. Its function is to convert the mechanical energy of power machines (such as electric motors and internal combustion engines) into liquid pressure energy. There are many factors that affect the service life of the hydraulic pump. In addition to the pump's own design and manufacturing factors, there are also some factors related to the selection of pump related components (such as couplings, oil filters, etc.) and the operation during commissioning.
The working principle of hydraulic pump is that the movement brings about the change of pump cavity volume, so as to compress the fluid and make the fluid have pressure energy.
The necessary condition is that the sealing volume of the pump cavity changes.

Cylinder Head

The cylinder head is installed on the top of the cylinder block, which seals the cylinder from the top and constitutes the combustion chamber.
The function of the cylinder head is to seal the cylinder, form a combustion space with the piston, and bear the effect of high temperature and high pressure gas. The cylinder head bears the mechanical load caused by gas force and tightening cylinder bolts, and also bears a high thermal load due to contact with high-temperature gas. In order to ensure the good sealing of the cylinder, the cylinder head shall not be damaged or deformed. For this reason, the cylinder head should have sufficient strength and rigidity.
