Abstract
<p>El modelo de utilidad protege una bomba de inyección de combustible de presión constante de tipo mecánico, incluye el cuerpo de bomba de inyección de combustible y el émbolo, el conjunto de válvula de descarga de aceite, el mecanismo de ajuste de cremallera, Ia placa de resorte superior, el asiento del resorte inferior, resorte del émbolo y el conjunto de pistón de guía. El manguito émbolo y el asiento inferior de válvula de aceite están diseñados para ser integrados, reduciendo así el número de superficie de acoplamiento y superficie de sellado de alta presión, simplificando los pasos y ciclos de procesamiento, mejorando Ia fiabilidad del manguito de émbolo. La instalación del émbolo será de tipo escápula, asegurando Ia fuerza de Ia zona de alta presión, y evita Ia deformación de agujero por compresión de manera efectiva, en el cuerpo de bomba de inyección de combustible hay múltiples canales de lubricante, simplificando el canal de aceite lubricante de motor diesel, hace que Ia estructura del diésel sea más compacta. Esta bomba de inyección de combustible de presión constante se utiliza para el trabajo coordinado del motor diesel marino en Ia línea de arreglo de cuatro tiempos, inyección directa, turbocompresor de gases de escape, de inter-refrigerador e irreversible, y satisface los requisitos de que Ia velocidad nominal del motor diésel es de 900~1200r/min, Ia potencia nominal de mono-cilíndrico es de 170~210 kW, el diámetro de cilindro es de Fi200~Fi250mm, el impulso es de 310~360mm.</p><p> The utility model protects a mechanical-type constant pressure fuel injection pump, includes the fuel injection pump body and the plunger, the oil discharge valve assembly, the zipper adjustment mechanism, The upper spring plate, the lower spring seat, the piston spring and the guide piston assembly. The piston sleeve and the lower oil valve seat are designed to be integrated, thus reducing the number of coupling surface and high pressure sealing surface, simplifying processing steps and cycles, improving the reliability of the piston sleeve. The installation of the piston will be of the scapula type, ensuring the strength of the high pressure area, and effectively preventing the deformation of the compression hole, in the fuel injection pump body there are multiple lubricant channels, simplifying the flow channel. Diesel engine lubricating oil makes the diesel structure more compact. This constant pressure fuel injection pump is used for the coordinated work of the marine diesel engine in the four-stroke arrangement line, direct injection, exhaust gas turbocharger, intercooler and irreversible, and satisfies the requirements that The nominal speed of the diesel engine is 900 ~ 1200r / min, the nominal power of mono-cylindrical is 170 ~ 210 kW, the cylinder diameter is Fi200 ~ Fi250mm, the pulse is 310 ~ 360mm. </p>
