Abstract
The utility model relates to a heating and pressurizing device for an oil-supply system of a diesel engine. An oil heater (4), an electric centrifugal booster pump (5), and control circuit are oddly arranged on an oil pipe (3) which is arranged on the position from an oil tank (1) of the oil supply system of the common diesel engine to a coarse strainer (2), and accordingly, the diesel engine can safely and reliably work under the condition of adopting any grade diesel oil in the low temperature environment.
Description
The utility model belongs to the common engineering parts, relates to a kind of heating, pressurization device for keeping fuel system for diesel engine normally to move in the winter time.
Now various is the motor of fuel with diesel oil, and winter, starting difficulty, abnormal main cause that turns round were that the low temperature flow and the vapo(u)rability of diesel oil itself is relatively poor.Chang Yong diesel oil is No. 0, negative No. 10 in the market, uses these the low trade mark diesel oil winter, because temperature is low, paraffin wax solidifies flow resistance and increases, and strainer easily blocks, and diesel engine can not be run well, and can't start when serious.Use high trade mark diesel oil (negative No. 35), though better mobile, cost an arm and a leg, under-supply, often influence the proper functioning of diesel engine.In order to improve the flowability of diesel oil under low temperature environment, Chinese patent 88210356 has been introduced a kind of oil pipe technological scheme that has heater element that is installed on the diesel engine, and this scheme is that resistance wire is directly placed oil pipe, although it is grounding measures is arranged, very unsafe in actual the use.In addition, the power of resistance wire is restricted, and improves the freedom of fuel flow poor effect.
The purpose of this utility model is the shortcoming that overcomes prior art, under the prerequisite that does not change ordinary diesel oil machine oil supply system structure, increase some auxiliary devices, make fuel system for diesel engine heating, pressurization, thereby can make diesel engine in any low temperature environment, adopt safe and reliable work under the situation of any trade mark diesel oil.
The utility model is achieved through the following technical solutions its goal of the invention.The heating pressurization device of fuel system for diesel engine is that the fuel tank in ordinary diesel oil machine oil supply system installs fuel heater, electronic centrifugal compression pump and control circuit additional to the oil pipe between the strainer.Its control circuit is that fuel heater and electronic centrifugal compression pump are parallel in the circuit of being made up of power supply and relay, power supply is through manual switch Access Control circuit by vehicle accumulator, also can be external 220V ac power supply, Access Control circuit behind transformer, bridge rectifier.Fuel heater is made of binding screw, tubulose heating unit, heat insulation layer, felt pad, electric heating wire, electric heating wire is distributed in the wire casing of tubulose heating unit according to power requirements, and lining insulate with felt pad, outermost has protected heat insulation layer, two of electric heating wire is connected with binding screw respectively, and the two ends of tubulose heating unit and oil pipe are with being threaded.Electronic centrifugal compression pump is made of ball bearing, shell, armature, magnetic field, brush, impeller, commutator, oil inlet pipe, oil outlet tube.
The utlity model has following advantage: owing to do not change the structure of original oil supply system, only set up a heating pressurization device, therefore reequiped simple and convenient; Diesel engine is to be powered behind depressurization and rectification by storage battery or 220V Ac at prestart, heater and electric centrifugal pump work, the fuel oil structure of molecule that is heated changes, improved flowability and vapo(u)rability, electric centrifugal pump is changed into malleation with the negative pressure fuel feeding of original oil supply system in addition, and thermal afterburning oil can be circulated in oil circuit, given heat whole oil circuit, therefore, under diesel oil function what low temperature in office, no matter adopt which kind of diesel oil all can reach the one push start success; Because the resistance wire of fuel heater does not contact with fuel oil, and is safe in utilization; Owing to adopt the diesel oil of the low trade mark, greatly reduce operation cost, economic benefit is very remarkable.In a word, the utlity model has and to make the environment of diesel engine at low temperature.The middle employing started smoothly advantage safe and reliable to operation, the good effect that having more cuts operating costs increases economic efficiency under the situation of hanging down trade mark fuel oil.
By embodiment the technical solution of the utility model further is illustrated in conjunction with the accompanying drawings.
Accompanying drawing 1 is a device schematic representation of the present utility model.
Accompanying drawing 2 is structural representations of fuel heater.
Accompanying drawing 3 is structural representations of electronic centrifugal compression pump.
Accompanying drawing 4 is heating, pressurized control circuit diagram of oil supply system.
As shown in Figure 1, a kind of heating of fuel system for diesel engine, pressurization device is to install fuel heater (4) at the fuel tank of ordinary diesel oil machine oil supply system (1) additional to the oil pipe (3) between the strainer (2), electronic centrifugal compression pump (5) and control circuit as shown in Figure 4, control circuit is with fuel heater (4) and electronic centrifugal compression pump (5), be parallel in the circuit of forming by power supply and relay (25), power supply is by manual switch (23) the Access Control circuit of vehicle accumulator (24) warp, also can be with external alternating current 220V power supply through transformer (21), bridge rectifier (22) back Access Control circuit.Fuel heater (4) is made of binding screw (10,11), tubulose heating unit (6), heat insulation layer (7), felt pad (8), electric heating wire (9) as shown in Figure 2; electric heating wire (9) is distributed in the wire casing of tubulose heating unit (6) totally four layers and lining with felt pad (8); outermost is protected with heat insulation layer (7); two of electric heating wire (9) is connected with (11) with binding screw (10) respectively, and the two ends of tubulose heating unit (6) are connected with oil pipe (3) with screw thread and seal.As shown in Figure 3, electronic centrifugal compression pump (5) is made of ball bearing (12), shell (20), armature (13), magnetic field (14), brush (15), impeller (16), commutator (19), oil inlet pipe (17), oil outlet tube (18).
