Abstract

The utility model discloses a quick-start low-temperature igniter for diesel engine. The device comprises a heating machine, a body, an electric application box, a water discharging valve, a water input pipe, a water output pipe and a base group, the utility model is characterized in that the electric application box consists of by a relay, a temperature switch and a conversion switch, an electric heating pipe is arranged in the electric heating machine. Connecting the water input pipe and the water output pipe with the outfall on the bottom of the diesel and the infall on the top of the diesel respectively, communicating the electricity of the electric application box, letting the heating work, and the water temperature in the diesel water tank can be increased and the water temperature can be kept in a set range, and the requirement to start the diesel at any time can be satisfied.

Description

Diesel engine started quickly at low temperature device

The utility model relates to a kind of heating equipment that diesel engine is started fast under low-temperature condition.

The diesel engine starting speed is subjected to the influence of ambient temperature very big, and when ambient temperature was low, diesel engine starting is difficulty relatively just, and Han Leng northern area is then particularly difficult in the winter time.For the emergent unit that requires at any time can both start at any time, this problem is more outstanding.Existing many technology are applied to the started quickly at low temperature of diesel engine, as patent CN97230925, CN91218402, but it is little that they all exist the ambient temperature effect of diesel engine, thereby make the startup stand-by period long, particularly can't make diesel engine keep the defective of the hot stand-by duty of startup at any time.

The purpose of this utility model is the defective that exists at prior art, a kind of diesel engine started quickly at low temperature device is provided, the coolant-temperature gage of diesel engine radiator is remained in user's setting range, to guarantee that diesel engine can start at any time fast under low temperature environment, thereby guaranteed the normal operation of cold area oil field in winter, train etc., also reduce simultaneously the wearing and tearing of parts and components of diesel engine, prolong the working life of diesel engine.

The utility model is realized by following scheme, diesel engine started quickly at low temperature device comprises heater, body, discharging valve, intake pipe, outlet pipe, base, also comprises by the second gear thermal switch of relay, different temperatures working value, the case for electrical apparatus that throw over switch constitutes; One electric heating tube is arranged in the heater, stretch in body, and form a circuit with relay, second gear thermal switch, throw over switch; The test point of thermal switch is on the intake pipe surface.

As improvement of the present utility model, on relay, there is a radiating fin to contact with the intake pipe surface, the heat of radiating fin can dissipate a part by intake pipe.

The utlity model has simple in structurely, easy to use, effective, can satisfy the characteristics that diesel engine starts needs at any time.

The utility model is described in further detail below in conjunction with the embodiment who optimizes and accompanying drawing.

Fig. 2: the plan view of Fig. 1 correspondence.

Fig. 3: embodiment 2 of the present utility model---diesel engine started quickly at low temperature device (vertical) plan view.

The A-A of Fig. 4: Fig. 3 is to sectional view.

Fig. 5: the utility model fundamental diagram (comprising circuit diagram).

As shown in Figure 1, 2, the utility model diesel engine started quickly at low temperature device is made up of heater 1, body 2, case for electrical apparatus 3, discharging valve 4, intake pipe 5, outlet pipe 6, base 7, body 2, intake pipe 5, the heater 1 of embodiment's 1 diesel engine started quickly at low temperature device (horizontal) are the level of state, outlet pipe 6 is communicated with body 2 upper right sides, its axis is vertical with body 2, intake pipe 5 is connected with body 2 left ends, case for electrical apparatus 3 is installed in the left side of body 2, and heater 1 is connected with body 2 right-hand members.

Shown in Fig. 3,4, the body 2 of embodiment's 2 diesel engine started quickly at low temperature devices (vertical), heater 1 are in vertical state, intake pipe 5, outlet pipe 6 are the level of state, intake pipe 5 is connected with body 2 left bottom sides, outlet pipe 6 is communicated with body 2 upper right sides, case for electrical apparatus 3 is installed in the downside of body 2, and heater 1 is connected with body 2 tops.

As shown in Figure 5, the electric heating tube Z in the heater stretches in body 2, and case for electrical apparatus comprises the second gear thermal switch KT of relay J, throw over switch K, different temperatures working value (the temperature height can be selected according to actual needs) _HAnd KT _L, relay J is in normally off, thermal switch KT _HAnd KT _LTest point be located on intake pipe 5 surfaces thermal switch KT _HAnd KT _LBe in normally open, throw over switch K is set in KT _HOr KT _LThe position.

Because relay contact switch J1 is in closed state, power supply is in case connect, electric heating tube Z just starts working, the temperature that enters the water in the body 2 is risen, because water " heat is light cold heavy ", the water after the heating can flow to outlet pipe 6, then intake pipe 5 can replenish the hot water that flows out, form siphonage, thereby the cold water in the diesel engine radiator 8 is circulated between intake pipe 5, body 2, outlet pipe 6 and diesel engine radiator 8, the coolant-temperature gage in the diesel engine radiator 8 is raise gradually.When the temperature of test point reaches the setting working value, thermal switch KT _HOr KT _LClosed immediately, the coil electricity in the relay J also produces magnetic field, and the contact switch J1 of relay J is disconnected, and electric heating tube Z dead electricity quits work.

When descending, water temperature make the temperature of test point on the intake pipe 5 drop to thermal switch KT _HOr KT _LAction down during value, thermal switch KT _HOr KT _LAgain disconnect, the contact switch J1 of relay J is closed again, electric heating tube Z switches on again, again feedwater heating, automatic reciprocating like this work remains in the scope of setting the water temperature of diesel engine radiator, thereby make diesel engine be in hot stand-by duty all the time, in case need work, just can start at once, and run on full load condition.
