Sensors be important Use for common rail system

High pressure common rail injection systemDiesel high-pressure common rail technology has gradually developed. The main core component of the high-pressure common rail injection system is the fuel injector. The high-pressure common rail injection system has the following characteristics: high inject

HEUI injector (working)HEUI injectors work with separate fuel injection cycles. The separate fuel injection cycle is divided into five stages:Before injectionPilot injectionInjection delayMain injectionRaiseBefore injection

The HEUI injector consists of three important partsUpper part, or actuator (A)Middle part, or pumping device (B)Lower part, or nozzle assembly (C)The upper part (A) includes the following parts:Solenoid valve (1)Armature spring (2)Armature (3)Seat pin (4)Spool valve spring (5)Spool valve (6)Intensif

Principle and structure of HEUI injector system for C9 engine of Caterpillar 336D excavatorHEUI has four functions. The HEUI injector pressurizes the supplied fuel from 450 kPa (65 psi) to 175 MPa (25382 psi). The HEUI injector functions as an atomizer by allowing high-pressure fuel to flow through

HEUI Injector TesterHUI-100 is a test device for grafted HEUI injectors. By installing a Bosch CP3 or CP2.2 common rail high-pressure pump as a hydraulic oil source on a common diesel high-pressure pump test bench, HUI-100 can complete a variety of HEUI injector maintenance and inspection tasks.

Step-by-step direct-acting solenoid valveThe step-by-step direct-acting solenoid valve combines the working principles of direct-acting and pilot-operated solenoid valves. When there is no pressure difference at the inlet and outlet or the pressure difference is too small to move the valve, the elec

Pilot solenoid valveWhen the pilot solenoid valve is energized, the solenoid generates electromagnetic force to open the pilot hole, which makes the pressure of the upper chamber drop sharply, forming a high pressure difference at the closing part, and then the closing part is pushed up by the press

Direct acting solenoid valveWhen the direct-acting solenoid valve is energized, the closing part is lifted from the valve seat to open the valve through the magnetic force generated by the solenoid coil to control the movement of the mechanical device; when the power is off, the electromagnetic forc

Classification of solenoid valvesSolenoid valves have a variety of classification methods, which can be divided into water solenoid valves, high pressure solenoid valves, and fire solenoid valves according to their functions. They can also be divided into direct-acting diaphragm structures and pilot

Introduction of working principle of solenoid valve Solenoid valve, whose English name is Electromagnetic value, is an automatic basic component used to control fluid. It is often used in industrial control systems to adjust the direction, flow, speed and other parameters of the medium. The s

FOTMA specializes in supplying VE pump heads, nozzles, plungers, bonnets, and delivery valvesFOTMA is a professional supplier of plunger components. The main products are VE distribution pump pump head (VE distribution pump pump head), fuel injection nozzle (fuel injection nozzle), plunger (plunger)
