Abstract

The utility model discloses a centralized cooling water circulating device which can reduce the environmental noise and fuel consumption of a diesel engine, and improve the power and radiating performance of the diesel engine. The centralized cooling water circulating device dispenses with a radiator and a fan of an existing diesel engine, and is installed far away from a diesel engine unit. As for the centralized cooling water circulating device, a water supply pump is arranged at a water outlet of a water storage tank and connected with a water inlet pipe of the diesel engine unit; a water outlet pipe of the diesel engine unit is connected with a water inlet of a radiator; and a temperature sensor is arranged at the water inlet of the device. The fan is arranged between a front radiator and a back radiator, and is connected with a fan motor through a belt pulley of a fan support by a belt. When cooling water enters a water jacket of the diesel engine unit through a water pump of the diesel engine after being pressurized by the water supply pump, under the action of a self-thermostat of the diesel engine, the cooling water goes in tiny circulation in the water jacket of the diesel engine; and when the temperature of the cooling water reaches a certain point, the thermostat turns on, great circulation is formed, and the cooling water flows to the radiators along the water outlet pipe; and when the information of water temperature is obtained, under the action of a temperature switch and a relay, the fan motor drives the fan to dissipate heat of the radiators.

Description

A kind of diesel coolant is concentrated circulation means
Affiliated technical field
The drilling well that the utility model relates in the oil exploration and development fields is concentrated a kind of device of circuit with diesel coolant.
Background technique
The heat radiation of diesel engine water circulation system is to rely on diesel engine self power to drive the radiation fan Coupler radiator is dispelled the heat in the wellbore construction process at present, and the huge wind-dryness that produces during owing to the radiation fan high speed rotating makes the operator be in all the time in the working environment of high noisy to the influence of environment; The radiation fan of high speed rotating when consuming diesel engine power because radiation fan is outwards radiator to be dispelled the heat, the various greases that diesel engine leaks out enter in the slit of radiator cooling tube wall outside in company with air stream, with the mixing of sand and dust under stop up cooling tube wall outside, very easily cause the bad diesel engine high temperature of heat radiation to damage; Under the cold snap situation, diesel engine starting is long preheat time, and oil consumption is big.
Summary of the invention
In order to overcome the deficiency of existing drilling well with the diesel coolant circulatory system, the utility model provides a kind of diesel coolant to concentrate circulation means, this device can not only reduce the noise of diesel engine, can also improve the useful horsepower of diesel engine and reduce oil consumption, and can carry out preheating to other diesel engine and stop up the high temperature damage that causes because of the outside greasy dirt of radiator cooling tube wall with solution.
The technological scheme that its technical problem that solves the utility model adopts is: cancel the circulating water radiator and the radiation fan of former single diesel engine, the concentrated circulation means of cooling water is being installed away from the place of diesel engine unit.The water outlet of the water storage tank of this device is equipped with raw water service pump and links to each other with the intake pipe of diesel engine unit, and raw water service pump provides the cooling water of certain pressure to use for diesel engine unit all the time.The diesel engine unit outlet pipe links to each other with water inlet of radiator, and the place is equipped with temperature transducer at water inlet of radiator.Before and after radiation fan places between the radiator, be connected with fan electromotor by belt through the belt pulley of fan bearing.When after cooling water is through the raw water service pump supercharging, entering in the diesel engine unit water jacket by diesel pump, under the effect of diesel engine self thermostat, cooling water carries out short circle in the diesel engine water jacket, when cooling water temperature reaches one regularly, thermostat is opened, and forms major cycle, and cooling water then flows to radiator along outlet pipe through behind the temperature transducer, under the effect of thermal switch and relay, radiator fan motor drives radiation fan radiator is dispelled the heat after obtaining water-exit temperature information.Inlet valve is installed in diesel engine cycle water water inlet, and flowing water Valve is installed in diesel engine cycle water water outlet place, opens or closes inlet valve, flowing water Valve can conveniently keep in repair and change diesel engine.Because the Hot swapping principle, cooling water can carry out preheating to other diesel engine of stopping using.
The beneficial effects of the utility model are can reduce diesel engine ambient noise and oil consumption, raising diesel engine power and heat dispersion.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is first embodiment's a tectonic maps.1,2,3,4 is diesel engine unit in Fig. 1,5. intake pipe, 6. inlet valve, 7. thermostat, 8. flowing water Valve, 9. outlet pipe, 10. temperature transducer, 11. thermal switches, 12. relays, 13. raw water service pumps, 14. water storage boxs, 15. fan electromotors, 16. back radiators.17. the fan bearing, 18. fans, 19. preceding radiators.
Embodiment
In embodiment shown in Fig. 1, water storage tank (14), radiator (16,19), radiation fan (18) and fan bearing (17), fan electromotor (15) are installed on the same base.The water outlet of water storage tank (14) is equipped with raw water service pump (13) and links to each other with the intake pipe (5) of diesel engine unit (1,2,3,4).Diesel engine unit (1,2,3,4) outlet pipes (9) link to each other with radiator (16,19) water intake, locate to be equipped with temperature transducer (10) at radiator (16,19) water intake and outlet pipe (9).Before and after radiation fan (18) places between radiators (16,19), be connected with fan electromotor (15) by belt through the belt pulley of fan bearing (17).Raw water service pump (13) starts after connecting power supply, in intake pipe (5), set up the cooling water of certain pressure, when starting wherein one or more diesel engine (1,2,3, when 4) working, the cooling water of certain pressure enters diesel engine unit (1 through inlet valve (6), 2,3,4) in the water jacket, when cooling water temperature reaches one regularly in diesel engine work, thermostat (7) is opened, cooling water then flows to radiator (16 along outlet pipe (9) through temperature transducer (10), 19), under the effect of thermal switch (11) and relay (12), fan electromotor (15) drive fan (18) is to passing through radiator (16 after obtaining water-exit temperature information, 19) Nei cooling water dispels the heat.Enter to pass through again behind the water storage tank (14) after raw water service pump (13) supercharging to enter once more in the diesel engine water jacket through the cooling water after the heat radiation and circulate by intake pipe (5).Inlet valve (6) is for often opening, be installed in diesel engine (1,2,3,4) circulating water water inlet, flowing water Valve (8) is for often opening, be installed in diesel engine (1,2,3,4) circulating water water outlet place, open or close inlet valve (6), flowing water Valve (8) can conveniently keep in repair and change diesel engine (1,2,3,4).Because the Hot swapping principle and the heat conduction principle of cooling water, other not have effect quilt that cooling water in diesel engine water jacket of work is subjected to the cooling water after raw water service pump (13) pressurization heat temperature raising gradually, so just plays the pre-heat effect to other diesel engine.Water storage tank (14), radiator (16,19), radiation fan (18) and fan bearing (17), fan electromotor (15) can be installed in away from diesel engine (1,2,3,4) operational site behind the pipeline of lengthening intake pipe (5) and outlet pipe (9), thereby reduce ambient noise.
