Problems solved by technology

The current heating device is the heating cycle of one diesel engine. If another diesel engine needs to be reconnected to the heating equipment and pipelines, or to install a heating device for each diesel engine, it is troublesome and wasteful.
[0005] 2. Preheat the cooling water, inject hot water into the cooling water tank to improve the start-up performance. It is necessary to release the original cold water first, and then inject the heated hot water, which is troublesome to operate.
However, the use of flammable fuels has certain risks, and safety measures need to be set up
[0008] 5. Use steam to heat the bottom shell of the diesel engine, and input the steam into the oil preheating pipe of the diesel engine bottom shell to make it warm up, but the heating range is only limited to the bottom of the diesel engine, and the diesel engine body cannot also be heated

Embodiment 1

[0033] Such as figure 1 As shown, the oil drilling rig diesel unit bridge type circulation preheating energy saving device includes diesel engines 1, 2, 3, controller 4, pump 5 and heater 6; the diesel engines 1, 2, 3 are respectively provided with cooling systems and located in The oil preheating pipe of the pan;

[0034] The water outlet of the pump 5 communicates with the water inlet of the heater 6 through a pipeline, and there are three branch pipelines connected in parallel between the water inlet of the pump 5 and the water outlet of the heater 6, and the three branch pipelines Electric reversing valve groups 7, 8, and 9 that can control the flow direction of branch pipelines are respectively installed on the road; the electric reversing valve groups 7, 8, and 9 are respectively connected to the sump oil preheating pipes of diesel engines 1, 2, and 3 through pipelines. The engine oil preheating pipe and the cooling system of the same diesel engine are independently ind...

Embodiment 2

[0040] Different from Example 1, such as figure 2 As shown, the electric reversing valve groups 7, 8, and 9 are L-shaped three-way electric ball valves respectively, and the L-shaped three-way electric ball valves are connected to the oil preheating pipe of the diesel engine through pipelines.

[0041] The electric reversing valve groups 7, 8, and 9 are L-shaped three-way electric ball valves, also known as switch types. Specifically, there are three states of the L-shaped three-way electric ball valves 7, 8, and 9, namely, the valve stroke There are three types: 0°, 90° and 180°, the valve can stop the flow of liquid at 0°, such as Figure 4 shown.

[0042] The present invention connects three diesel engine sump oil preheating pipes with pipelines through the above two embodiments, the oil preheating pipes and cooling system are connected with pipelines, and then the cooling systems of the three diesel engines are connected at the same water level, combined The circuit sys...

Abstract

The invention discloses an oil rig diesel engine set bridge-type circulating pre-heating energy-saving device. Cooling systems of three diesel engines are connected with bottom case engine oil pre-heating pipes respectively through pipelines, and a pump is arranged to force water circulation on the pipelines. Spare heat of one working diesel engine is used for heating the non-working diesel engines to enable the non-working diesel engines to be pre-heated so that pre-heating time of cold vehicle starting can be reduced and operation time of a heat-dissipating fan of the working engine can be reduced, and therefore the energy-saving and consumption-reducing purposes are achieved. A heater is connected to a water inlet pipeline, and then heating can be conducted when no engine is started, and heat is transmitted through the pump, therefore, starting time of the diesel engines can be effectively shortened and working efficiency can be improved particularly when outdoor temperature is low.

Description

technical field [0001] The invention relates to the technical field of diesel engines, in particular to a bridge-type circulation preheating and energy-saving device for oil drilling rig diesel units. Background technique [0002] In oil drilling, diesel engines are the main power source. Under normal circumstances, three diesel engines work in a cycle. On the one hand, when the diesel engine is working, the fuel burns and the heat generated by the friction of moving parts increases the temperature of the diesel engine and affects the normal operation of the diesel engine. It is necessary to cool the diesel engine with cooling water to keep the diesel engine in the normal operating temperature range. On the other hand, since the diesel engine relies on compression and self-ignition of the fuel, it is more difficult to start in a cold state, especially when the ambient temperature is low. In order to reduce the starting power required for starting and make the diesel engine...
