Mounting structure for adapter of diesel oil filter

Abstract

The invention discloses a mounting structure for an adapter of a diesel oil filter. The mounting structure for the adapter of the diesel oil filter comprises a filter seat and the adapter; the filterseat is provided with an oil outlet channel and an oil inlet channel; oil inlets are formed in the two ends of the oil inlet channel correspondingly and are both plain hole connectors; and mounting threaded holes are formed in the two sides of the oil inlets. The adapter comprises a flange disc and an oil channel plug; mounting holes are formed in the two sides of the flange disc correspondingly;a threaded through hole is formed in the middle of the oil channel plug; and an O-shaped ring groove is formed in the inner side of the oil channel plug. According to the mounting structure for the adapter of the diesel oil filter, a filter connector of an assembly rod type heater can be changed from the connector mode with the relatively fixed and unique direction into the mode that the connectordirection can be selected at random, a filter manufacturer only needs to form a set of filter seat molds, the multiple requirements of users for the filter connector direction, number, whether the heater is equipped and the like can be met, and the production cost can be significantly lowered.

Description

technical field [0001] The invention relates to the field of engines, in particular to an installation structure of a diesel filter adapter. Background technique [0002] Because diesel oil contains paraffin wax, it is easy to precipitate and adhere to the filter medium in low temperature environment, which will affect the fluidity of diesel oil, and then affect the start-up and performance of the engine. Especially in some severe cold areas, most diesel locomotives will choose to be equipped with diesel heaters due to the difficulty in starting the engine and insufficient power due to low temperature. Diesel heating methods currently used in the market are various, such as pipe wrap heating, return oil heating, diesel filter tank wrap heating, disc heating integrated on the filter, and rods inserted into the oil passage of the filter type heater. The stick heater is of modular design and can be supplied assembled with a diesel filter, the so-called heatable diesel filter....

AI Technical Summary

Problems solved by technology

[0004] Currently, filters equipped with rod heaters are limited by the structure of the heater. This type of filter can only have one oil inlet with a unique direction, which cannot meet the user's requirements for the diversity of filter oil inlets. select requirements

And in order to meet the different needs of different users or different products for the direction of the oil inlet, at least two to three sets of filter seat molds must be opened at the same time for the same filter (some users need to install a heater on the left side of the filter, and a heater on the right side). The side is used as the oil inlet of the filter; some users need to install a heater on the right side of the filter, and the left side is used as the oil inlet of the filter; some users need to use this filter, but do not need a heater at all , and due to the variety of supporting products of the filter, the oil inlets on the left and right sides of the filter are required), so that the production cost is greatly increased
