[0002] In the methanol production process, the coal gas produced by the coke oven needs to be compressed by a reciprocating compressor and then transported to the purification and conversion process. The compressor lubrication system and the oiler lubrication system have a very important impact on the operation effect and service life of the reciprocating compressor. However, the oiler lubrication system of the reciprocating compressor in the prior art does not equip the oiler tank with an automatic refueling system. It only has a refueling port on the upper part of the oiler tank, and a refueling port cover is matched on the refueling port. When the oiler tank needs to be refueled, workers usually go back and forth from the warehouse to get the lubricating oil, and then remove the refueling port cover to manually add the lubricating oil. On the one hand, it wastes manpower; on the other hand, it is easy to spill and leak oil during manual refueling, which not only causes waste of lubricating oil, but also pollutes the factory environment.

[0005] Furthermore, a second control valve is connected to one end of the oil filling pipe located at the oil filling port.

[0006] Furthermore, the oil filling pipe is a stainless steel pipe.

DETAILED DESCRIPTION

[0016] The following is a further description of the embodiments of the present invention in conjunction with the accompanying drawings:

[0017] Embodiment 1:

[0018] like Figure 1 As shown, the automatic refueling system of the reciprocating compressor oiler tank described in the utility model includes an oiler tank 7, a compressor oil pump 1 and a compressor lubrication pipeline 3. The oiler tank 7 is provided with a liquid level gauge 8 and a refueling port 9, and a refueling port cover 10 is connected to the corresponding refueling port 9. The refueling port cover 10 is provided with a plug hole 11. The compressor lubrication pipeline 3 is connected to the oil outlet of the compressor oil pump 1. The compressor lubrication pipeline 3 is connected to a first tee 2, and the first tee 2 is connected to an oil filling pipe 6. The other end of the oil filling pipe 6 is inserted into the oiler tank 7 through the plug hole 11 and the refueling port 9. The oil filling pipe 6 is connected to an oil filter 5, and the oil filling pipe 6 located at the front end of the oil filter 5 is connected to a first control valve 4.

[0019] During use, the liquid level of the lubricating oil in the lubricator tank 7 can be observed from the liquid level gauge 8. When lubricating oil needs to be added, the first control valve 4 is opened, and the compressor oil pump 1 pumps the lubricating oil in the compressor tank into the compressor lubrication pipeline 3, wherein a portion of the lubricating oil will enter the oil filter 5 through the first tee 2, the oil filling pipe 6 and the first control valve 4, and the lubricating oil filtered by the oil filter 5 continues to enter the lubricator tank 7 through the oil filling pipe 6, thereby adding lubricating oil to the lubricator tank 7. When it is observed from the liquid level gauge 8 that the lubricating oil level in the lubricator tank 7 rises to the required level, the first control valve 4 can be closed. Since the aperture of the jack 11 is larger than the aperture of the oil filling pipe 6, the air pressure balance inside and outside the lubricator tank 7 can be ensured.

[0020] The automatic refueling system for the oil tank of the reciprocating compressor oil injector described in the utility model can filter the lubricating oil in the compressor lubrication system and introduce it into the oil tank 7 of the oil injector, thereby realizing automatic refueling of the oil tank 7 of the oil injector, which not only saves manpower but also prevents spillage and waste when the lubricating oil is manually added.

[0021] Embodiment 2:

[0022] like Figure 2 , Figure 3 As shown, based on Example 1,

[0023] Furthermore, a second control valve 14 is connected to one end of the oil filling pipe 6 located at the oil filling port 9. When the system is running, the first control valve 4 is in a normally open state. The addition and stopping of lubricating oil in the oil filling tank 7 are controlled by controlling the opening and closing of the second control valve 14. Since the second control valve 14 is close to the liquid level gauge 8, when the worker observes that the lubricating oil in the oil filling tank 7 is insufficient, the second control valve 14 can be opened in time without running to the compressor oil pump 1 to open the first control valve 4, which is very convenient to operate.

[0024] Furthermore, the oil filling pipe 6 is a stainless steel pipe, which is strong and durable on the one hand, and easy to position on the other hand;

[0025] Furthermore, the oil filling pipe 6 is connected with a second tee 12, which is located at the rear end of the oil filter 5. The second tee 12 is connected with a pressure gauge 13, which can monitor the oil filling pressure to determine when to clean the oil filter 5;

[0026] Furthermore, the fuel filler cap plate 10 is connected with a dust cover 15 corresponding to the insertion hole 11, and a plurality of vent holes 16 are provided on the side wall of the dust cover 15. The fuel filling pipe 6 passes through the dust cover 15, and the vent holes 16 on the dust cover 15 are used to balance the air pressure inside and outside the fuel tank 7 of the fuel injector. On the one hand, the dust cover 15 can prevent dust from entering the fuel tank 7 of the fuel injector through the insertion hole 11, thereby playing a dust-proof role; on the other hand, the dust cover 15 can assist in positioning the fuel filling pipe 6, thereby making the structure of the fuel filling pipe 6 more stable.

[0027] Furthermore, the dust cover 15 is made of plastic, which is cheap and easy to assemble.
