The low ambient temperature affects the starting of the engine. At the same time, the low temperature will also cause the viscosity of the screw machine lubricating oil to increase, making it difficult to start the air compressor. During startup, the air compressor head may even be stuck due to insufficient oil supply caused by the high oil viscosity. Utility Model Content

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a lubricating oil preheating device before starting a diesel-driven screw air compressor, comprising a fixing seat, which is a hollow heating cavity closed on all sides;

[0006] The preheating component is arranged on a fixed seat, and the preheating component includes an oil and gas barrel, a fuel heater, a fuel heater exhaust pipe, an exhaust pipe fixing plate and a plurality of exhaust holes. The plurality of exhaust holes are all opened on the fixed seat, the oil and gas barrel is fixedly installed on the fixed seat, the fuel heater is fixedly installed on the fixed seat, and the fuel heater exhaust pipe is connected to the fixed seat.

[0007] Preferably, the oil and gas barrel is filled with air compressor lubricating oil.

[0008] Preferably, the fuel heater smoke exhaust pipe is connected to the smoke exhaust end of the fuel heater, and the fuel heater smoke exhaust pipe is fixedly connected to the fuel heater.

[0009] Preferably, one end of the exhaust pipe fixing plate fixedly supports the exhaust pipe of the fuel heater, and the other end of the exhaust pipe fixing plate is fixedly connected to the fixing seat.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] 1. The diesel-driven screw air compressor is equipped with a fuel heater to generate heat by burning diesel to heat the engine's antifreeze circulation so that the engine can reach a normal starting temperature before starting. The fuel heater will discharge high-temperature exhaust gas during operation. Generally, this exhaust gas will be directly discharged into the external environment of the air compressor housing. The heat of the exhaust gas discharged by the fuel heater is used to heat the air compressor lubricating oil, so that the air compressor lubricating oil can be raised to a certain temperature before starting, thereby improving the fluidity of the lubricating oil and enabling the air compressor to start normally.
