Abstract
The utility model relates to an automatic fan pneumatically controlled constant temperature device installed on a diesel engine for an oil rig, comprising the combination of a pneumatic control valve and heat sensitive components, which are fixedly connected together by screws. The device is easy to mount and dismount. Because of no rotating parts and less wearing parts, the durability and the reliability are all raised. The sensitivity regulation aspect can safely satisfy the requirement of the cooling temperature of the diesel engine. The temperature can be accurately constantly fixed at a range from 75 DEG C. to 85 DEG C.
Description
The utility model be on the diesel engine used of oil-well rig mounted fan from taking offence constant temperature device.
190 diesel engines that existing rig uses do not have automatic thermostatic device, are to control fan with manual operation to regulate temperature, and it requires operator person strictly to observe the diesel engine radiator temperature, start at any time or close fan clutch and receive constant water temperature.Be to be difficult to avoid personal factor such as negligence in this case, cause material oil machine to move under the conditioned disjunction low temperature of high temperature, cause accelerating component wear, fuel consumption increases, and the thermal efficiency reduces adverse consequences.
The utility model proposes of task is: make diesel engine all keep constant operating temperature under any working condition, reduce the power loss of diesel engine, and fuel consumption, reduce operator's labor intensity, design this diesel engine fan automatic gas control constant temperature device, overcome the shortcoming of prior art.
The combination of the utility model Pneumatic valve and thermosensitive element, and be connected together with retaining screw.Pneumatic valve is made up of the exhaust port 5 on valve member 1, spring 2, valve piece 3, valve rod 4, the valve rod, the exhaust port 6 on the valve body, adjustment screw 7, retaining screw 8, suction port 11, relief opening 12.Diesel engine return pipe 9 is arranged in the thermosensitive element 10; Pneumatic valve and thermosensitive element make up, and link together with retaining screw; The length dimension of valve rod 4 is 30～40mm, and adjusting screw 7 is of a size of 20～25mm.This device is achieved in that when carrying out automatic control, the thermosensitive element 10 that is installed in the diesel engine water outlet raises along with the diesel engine water temperature and expands, it is up to promote valve rod 4, back down valve piece 3, the gas of main tracheae line enters air feeding apparatus by valve rod 4 external series gaps to relief opening 12, temperature is elevated to one regularly, the suction pressure of air feeding apparatus increases, overcome the air feeding apparatus spring force, open main line inlet hole 11 in the air feeding apparatus, gas enters the clutch fan and rotates, and reduces water temperature, when temperature is reduced to certain value, temperature-sensitive original paper 10 shrinks, and valve rod 4 is descending under the effect of spring 2, valve piece 3 sealing suction ports 11, at this moment the exhaust port on the valve rod 5 is connected exhaust with the exhaust port 6 on the valve body, and cause the rapid-release valve exhaust, and end pressure descends in the air feeding apparatus, and valve body is closed inlet hole under the effect of spring, open exhaust port simultaneously the gas in the clutch is discharged, fan stops operating, cooling suspends.
Automatic gas control constant temperature device of the present utility model is to adopt full gas control to control fan automatically, adjusts water temperature, it is compared with domestic existing like product such as power Coupler, simple in structure, easy installation, dismounting, owing to there is not the rotatable parts few easy workout part, serviceability and safety reliability all improve greatly.Can satisfy the requirement of diesel engine safely aspect the adjustment sensitivity to chilling temperature, with the accurately constant scope at 75 ℃～85 ℃ of temperature, and can adjust the temperature range of control as required, prolong the working life of diesel engine, make full use of the thermal efficiency, improve diesel engine power, prevent accident potential, compare fuel-economizing about 30% with former diesel engine.This device is easy for operation, auto-manual characteristics nimbly and freely.
Accompanying drawing 1 is a diesel engine fan automatic gas control constant temperature device.
1, the exhaust port, 6 on valve body, 2, spring, 3, valve piece, 4, valve rod, 5, the valve rod, the exhaust port, 7 on the valve body, adjustment screw, 8, retaining screw, 9, diesel engine return pipe, 10, thermosensitive element, 11, suction port, 12, air outlet.
Claims (3)
1, the utility model is a mounted fan automatic gas control constant temperature device on the diesel engine used of oil-well rig.It has Pneumatic valve, thermosensitive element, it is characterized in that: the combination of Pneumatic valve and thermosensitive element, and link together with retaining screw.
2, by the described constant temperature device of claim 1, it is characterized in that: be fixed on the diesel engine return piping, the length dimension of valve rod is 30～40mm, and adjusting screw is of a size of 20～25mm.
3, by claim 1 or 2 described constant temperature devices, it is characterized in that: temperature is 75 ℃～85 ℃.
