Description
Technical field
The utility model relates to mechanical field, particularly a kind of diesel generator forced water circulation water pre-heater apparatus.
Background technique
Diesel generating set is a kind of power equipment commonly used, and the diesel engine of diesel generating set is lowered the temperature to cylinder body by water circulation when work.But diesel engine starts diesel oil by High Temperature High Pressure again naturally, therefore, during diesel engine starting, the height of center housing temperature, very large on starting the diesel engine impact, especially in the low situation of ambient temperature, affect larger.At present, the diesel generator of power supply generally all is provided with and starts unsuccessfully protection for three times in support, namely can not start for three times successfully after, unit will automatic shield startup loop, and can not restart, and has so just lost the meaning of back-up power.And mostly adopt in the market the self-circulation type water pre-heater apparatus, this kind water pre-heater apparatus efficiency of heating surface is low, energy consumption is large, local temperature difference is large, often owing near the temperature water pre-heater apparatus reaches setting temperature device is quit work, and this moment is also lower than the diesel cylinder sleeve coolant-temperature gage of distant positions from device, like this, even the diesel generating set of self-circulating water Preheating unit is housed, it is also relatively low that it starts success rate.Therefore, the improvement and bring new ideas of water pre-heater apparatus is the problem of needing at present solution badly.
Summary of the invention
For above-mentioned situation, for solving the defective of prior art, the purpose of the utility model just provides a kind of diesel generator forced water circulation water pre-heater apparatus, can effectively solve the not smooth problem of present diesel generating set diesel cylinder sleeve water circulation.
The technological scheme that the utility model solves is, comprise housing, support, water pump, heater and electric control box, housing is welded on the support, and an end of housing has water intake, water outlet is arranged at housing top, the dewatering outlet is arranged at the bottom, and housing one end is equipped with the heater that places in the housing, and heater and housing joint are provided with isolation layer, there is the wiring terminal that links to each other with heater the isolation layer outside, water outlet is connected with water pump, and wire connecting hole is arranged on the water pump, and electric control box links to each other with water pump, wiring terminal.
The utility model structure is unique, and volume is little, and is easy to use, and preheating is fast, but constant temperature is easy for installation, easy care, and non-environmental-pollution is the innovation on the water pre-heater apparatus.
Description of drawings
Fig. 1 is structural front view of the present utility model.
Fig. 2 is structure master's pseudosection of the present utility model.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
Provided by Fig. 1-2, the utility model comprises housing 4, support 10, water pump 5, heater 19 and electric control box 3, housing 4 is welded on the support 10, one end of housing 4 has water intake 1, water outlet 6 is arranged at housing 4 tops, dewatering outlet 9 is arranged at the bottom, housing 4 one ends are equipped with the heater 19 that places in the housing, heater 19 is provided with isolation layer 15 with housing 4 joints, there is the wiring terminal 16 that links to each other with heater 19 isolation layer 15 outsides, water outlet 6 is connected with water pump 5, and wire connecting hole 14 is arranged on the water pump 5, and electric control box 3 links to each other with water pump 5, wiring terminal 16.
There is insulating protective cover 7 described wiring terminal 16 outsides, are provided with wire outlet 8 above the insulating protective cover 7.
One-way valve 20 is equipped with in described water intake 1 inboard.
The temperature detect switch (TDS) 13 that links to each other with heater 19 is arranged in the described electric control box 3.
Described electric control box 3 rear boards are provided with wire inlet-outlet 2, and door lock 11 and work indicator light 12 are housed on the front panel.
The thermocouple 18 of test water temperature is equipped with in described housing 4 interior bottoms, and thermocouple 18 links to each other with thermocouple junction 17 in placing insulating protective cover 7, and thermocouple junction 17 links to each other with electric control box 3 through wire.
In order to guarantee that the utility model diesel generator forced water circulation water pre-heater apparatus can normally move, need to connect ABAP Adapter, ABAP Adapter is from electric control box rear board wire inlet-outlet access electric control box, by temperature detect switch (TDS) water pump and heater; The data transmission that thermocouple detects is to temperature detect switch (TDS), and temperature detect switch (TDS) compares according to the numerical value of the temperature range of setting and thermocouple input, controls running on of whole device and stops.
Use condition of the present utility model is: the cooling water of high water level water outlet is through device water intake (power resources are water pump) in the diesel cylinder sleeve, open one-way valve by hydraulic pressure and flow into housing, flowed in the diesel engine low water level cylinder sleeve by water outlet after the heater via heating, because water velocity is than very fast, water in the cylinder sleeve is fully heated, and do not stay the dead angle.To Preheating unit access (AC220V or AC380V are optional) working power, through temperature detect switch (TDS) (25 ℃ ~ 85 ℃ can arrange voluntarily), temperature detect switch (TDS) is according to the real time temperature of the thermocouple measurement water temperature in its thermometric post and conducting or disconnection are controlled to the power supply of heater and water pump and supplied with.When the water temperature that records when thermocouple is lower than the lower limit of setting value, the closed turn-on power of temperature detect switch (TDS), heater and water pump are started working, and work indicator light is bright.When being heated to the CLV ceiling limit value of setting value, temperature detect switch (TDS) disconnects the power supply of heater and water pump, quits work, and work indicator light extinguishes.
