Rod-type heating diesel oil filter

Abstract

The invention discloses a rod-type heating diesel oil filter. The rod-type heating diesel oil filter comprises a filter element assembly, a filter base, a rod-type heater and a conversion joint, wherein the filter base is provided with an oil outlet channel and an oil inlet channel, oil inlets are formed in both ends of the oil inlet channel, the oil inlets are unthreaded hole interfaces, an mounting threaded holes are formed in both sides of the oil inlets. The conversion joint comprises a flange plate and an oil channel plug, wherein mounting holes are separately formed in two sides of the flange plate, a threaded through hole is formed in the center of the oil channel plug, and an O-type ring groove is formed in the inner side of the oil channel plug. The conversion joint of the rod-type heating diesel oil filter can change the filter interface provided with the rod-type heater from a relatively fixed direction and a unique interface form to an interface direction which can be selected at will, filter manufacturers only need to set up a set of filter base mold to meet various requirements of different users on the filter interface direction, number, whether the heater is arranged or not, and the production cost can be greatly reduced.

Description

technical field [0001] The invention relates to the field of engines, in particular to a rod type heating diesel oil filter. 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. Customers can ...

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
