Abstract
The invention discloses a water/explosion-proof encapsulated electromagnet for an electronic unit pump. The water/explosion-proof encapsulated electromagnet comprises a terminal lead, a casing, an iron core, a coil support, a coil, an iron core stand, and a terminal, wherein a protection cover is made of a metal material, and is divided to an upper part and a lower part, i.e. an upper protection cover and a lower protection cover; the terminal and the boss part of the terminal are completely sealed by the upper protection cover; a lead is extracted out of the protection cover through a lead hole on the top of the upper protection cover; and the remaining space in the upper protection cover is filled with sealant. According to the invention, the terminal is no longer exposed to the working environment so as to reduce the possibility of occurrence of electric leakage and electric sparks; the heat dissipation area of the terminal part is enlarged; the sealing performance between the terminal and the coil lead is enhanced to prevent penetration of rain water and fuel; and the metal protection cover can also suppress the influences of external severe environments on the electromagnet, and has water/explosion-proof function and long service life. The water/explosion-proof encapsulated electromagnet can achieve quick on-off by receiving control signals of an electronic control unit when used for an electronic unit pump system.
Description
Technical field
The present invention relates to a kind of high-speed electro-magnet that is used for electronically controlled unit pump, relate in particular to a kind of electronically controlled unit pump with waterproof anti-explosion pouring type electromagnet with waterproof anti-explosion function.
Background technology
Since electric control diesel power set some advantages in energy-saving and emission-reduction, the trend of the times of automatically controlledization of Diesel engine.The electronically controlled unit pump technology is to realize wherein a kind of means of automatically controlledization of diesel powerplant, and it makes burning be more suitable for the needs of operating mode, has reduced exhaust pollution and fuel consumption, and America and European famous engine producer all extensively adopt the electronically controlled unit pump technology.Electronically controlled unit pump needs the coupling of electromagnetically operated valve when work, the switch electromagnetic valve that possesses high speed performance just becomes one of crucial executive component.And the keying function of realization electromagnetically operated valve just needs electromagnet.Electromagnet is the control monoblock pump key of oil spout at regular time and quantity.Tradition unit pump electromagnet product comprises housing, coil, coil bracket, iron core and binding post, and coil is contained on the coil bracket after being wrapped on the iron core, and places in the housing, and the end points of coil is connected with binding post.Tradition unit pump electromagnet binding post part even be exposed to fully in the surrounding working environment, because binding post is smooth, rainwater and fuel oil are penetrated into enclosure interior along the shiny surface of binding post easily, form the electromagnet product rejection; In addition under the effect of long-time electric current; The binding post place is easy to form local high temperature; When energising, also might produce reasons such as electric spark; Make traditional monoblock pump exist the application of the specific environment of methane gas and flammable explosive gas to be restricted, and then limited the application of diesel powerplant in coal mine etc.
Summary of the invention
The objective of the invention is to: overcome the deficiency of the conventional art of mentioning in the background technology, provide a kind of electronically controlled unit pump with waterproof anti-explosion pouring type electromagnet.
The technical solution adopted for the present invention to solve the technical problems is: comprise the binding post lead-in wire, housing, iron core, coil bracket; Coil, the iron core support, binding post, coil are wrapped on the coil bracket; Be installed on the iron core, iron core is installed on the iron core support, and places in the electromagnet housing; The end points of coil is connected with binding post, sets up safety guard in the housing periphery, and safety guard is processed by metal material; Two parts are top safety guard and bottom safety guard about being divided into, and binding post and binding post projection section are sealed by the upper metal safety guard fully, and lead-in wire is passed by the fairlead at upper metal safety guard top.
The present invention's remaining space in the upper metal safety guard is filled with fluid sealant.
Binding post according to the invention by bottom safety guard parcel, only exposes the electromagnet core face with the lower part electromagnet.
Fluid sealant according to the invention adopts the H907 epoxy pouring sealant.
Connection binding post lead-in wire according to the invention adopts the colliery to move light-duty rubber sleeve flexible cable.The invention has the beneficial effects as follows; Binding post no longer is exposed in the operational environment, has reduced the possibility that electric leakage and electric spark take place, increased the area of dissipation of binding post part; Strengthened the sealing between binding post and the coil lead; Prevent the infiltration of rainwater and fuel oil, the metal safety guard also can limit outside adverse circumstances to the influence that electromagnet produces, and possesses the function of waterproof anti-explosion.When being applicable to the electronically controlled unit pump system, realize fast opening and closing through the control signal of accepting electronic control unit.
