Abstract
The utility model provides a diesel oil way preheating system. The internal end of an oil outlet pipe (6) is fixedly provided with a closed heating pipe (8) extending to the oil outlet pipe (6). The internal end of the oil outlet pipe (6) is further fixedly provided with a long-strip-shaped positive temperature coefficient (PTC) heating body (9) which extends to the heating pipe (8). The moving direction of the PTC heating body (9) is consistent with that of the oil outlet pipe (6). A tube wall of the oil outlet pipe (6) is provided with a plurality of oil inlet holes (10). As the long-strip-shaped PTC has certain length, heat dissipation area is greatly improved, heating efficiency of the oil outlet pipe is further greatly improved, and demanded quantity of electrical energy is reduced.
Description
Technical field
The utility model relates to a kind of diesel oil oil circuit pre-heating system.
Background technique
When ambient temperature was low, the oil supply system of diesel locomotive needed preheating, flowed to guarantee that fuel oil is smooth and easy, and motor starts and proper functioning smoothly.A kind of diesel oil oil circuit pre-heating system is arranged in the existing technology, and its oil outlet tube the inner is equipped with block PTC pottery, utilizes the heating of PTC ceramic plate to the heating that circulates of the superconductive medium in the oil outlet tube, and superconductive medium is passed to the diesel oil in the oil outlet tube through heating pipe with heat.The shortcoming of this mode is: the first, complex structure, and manufacture cost is high; The second, superconductive medium has strict demand to start-up temperature, can't normal circulation when ambient temperature is low; Three, this design has certain requirement to the setting angle of oil outlet tube, and the field of employment is limited.
Also has a kind of diesel oil preheating mode in the existing technology; The placement heating unit carries out preheating to the fuel oil of oil-way system in strainer, and its shortcoming is: the first, need the dismounting strainer, install complicated; The vehicle that has; Such as " state's III " vehicle, do not allow strainer is reequiped, therefore can't adopt the method for built-in heating unit; The second, built-in heating unit takies the filter core space, influences fuel flow.
In the existing technology, also having a kind of preheating method is in the tube wall interlayer of transport pipe, heating unit to be set, or the straight line shape heating wire is set in tube wall, the low shortcoming of they ubiquity efficiencies of heating surface.
The model utility content
The utility model technical problem to be solved is, a kind of diesel oil oil circuit pre-heating system is provided, and has simple and practical structure and the heat exchange efficiency of Geng Gao, to overcome the defective of existing diesel oil oil circuit pre-heating system.
It is following that the utility model solves the problems of the technologies described above the technological scheme that is adopted:
A kind of diesel oil oil circuit pre-heating system; Comprise the oil outlet tube that is used for being inserted into fuel tank; Be used for external heating equipment to the prefilter element heating; Be used to connect said oil outlet tube with prefilter element and the transport pipe that is used to be connected prefilter element and motor, it is characterized in that: the inner of said oil outlet tube is installed with the closed heating pipe that is deep in the oil outlet tube; The inner of said oil outlet tube also is installed with and is deep in the said heating pipe and trend and the consistent strip PTC heating unit of said oil outlet tube trend; On the tube wall of said oil outlet tube, offer several oil inlet holes.
Said external heating equipment is a sleeve of the equal opening in two ends up and down, and the barrel of this sleeve is built-in with the heating film that one deck connects lead outward.
Said transport pipe is built-in with a thread spiral heating body that connects lead outward, and the inwall of said thread spiral heating body and transport pipe fits.
The length of said PTC heating unit is between 100～180mm.
The good effect of the utility model is:
The first, with block PTC ceramic phase ratio, strip PTC has certain-length, so heat diffusion area increases substantially, and then has increased substantially the efficiency of heating surface of oil outlet tube and reduced the demand to electric energy simultaneously.The oil outlet tube structure of the utility model is simpler, and manufacture cost is more reasonable.According to the design of the utility model oil outlet tube, the setting angle to oil outlet tube when installing and using does not require, and the application place is more extensive, such as being installed in easily in the fuel tank of vehicles such as excavator, forklift.
The second, owing to needn't reequip strainer when installing and using, the external heating equipment of strainer is easier for installation, and Applicable scope is wider.
Three, heating unit adopts helical design in the transport pipe, and direct and fuel oil contact heating, and heat exchange efficiency is higher.
