Description

Technical Field

[0001] The utility model relates to the technical field of oil and gas mining equipment, in particular to a liquid filling auxiliary device and a gas compressor. Background Art

[0002] A gas compressor is a device commonly found in oil and gas production well stations, used to compress and pressurize gas, such as natural gas, for transportation. Gas compressors lose oil during use, so they need to be refilled with oil regularly. The oil tanks of gas compressors used in existing well stations are mostly located at the upper rear end of the fuselage. When refilling the oil, the oil barrel needs to be moved to the top of the oil tank by manpower, and then refilled through the breathing valve cylinder head. However, the height of the breathing valve cylinder head is often high, and the weight of the oil barrel is often large, so the oil refilling operation is very time-consuming and labor-intensive, and there is a certain safety hazard of the oil barrel and the workers falling from a height. Therefore, a new oil refilling method is urgently needed. Utility Model Content

[0003] The purpose of the utility model is to overcome the technical problems that the height of the breathing valve cylinder head of the existing gas compressor is too high, which makes the oil filling operation time-consuming and labor-intensive, and there is a safety hazard of falling from a high altitude, and to provide a liquid filling auxiliary device and a gas compressor.

[0004] In a first aspect, the present invention provides a liquid filling auxiliary device, comprising:

[0005] Storage tank, the storage tank is used to store liquid, and is provided with a filling port and a liquid outlet;

[0006] The delivery pipeline comprises a first port and a second port, the first port being connected to the liquid outlet, the second port being used to connect to the device to be filled, and the height of the second port being no lower than that of the filling port;

[0007] The pump body is arranged on the delivery pipeline and is used to drive the liquid in the storage tank to flow to the equipment to be filled.

[0008] The delivery pipeline includes but is not limited to a hard pipeline, such as a metal pipeline; or a soft pipeline, such as a metal braided pipeline, a metal bellows, and a plastic hose.

[0009] The pump body includes but is not limited to centrifugal pumps, vortex pumps, mixed flow pumps, axial flow pumps, etc.

[0010] Taking the case where the equipment to be filled is a gas compressor and needs to be filled with engine oil as an example, when using the liquid filling auxiliary device of this solution, the second port is connected to the breathing valve cylinder cover of the gas compressor, and engine oil is added to the storage tank from the filling port; then the pump body is started to make the engine oil flow along the delivery pipeline to the second port at a high position, and finally enter the gas compressor, completing the oil filling function.

[0011] As can be seen from the above, the liquid filling auxiliary device of this solution connects the storage tank with the equipment to be filled through a conveying pipe. When liquid filling is required, the staff does not need to carry the oil barrel to a high place first as in the existing solution. Instead, they only need to add liquid to the storage tank at a lower place and start the pump to complete the liquid filling operation. The filling process is convenient and fast, consumes less manpower, and there is no risk of the oil barrel and the staff falling from a high altitude, which is safer.

[0012] Preferably, at least one of the delivery pipe, the filling port, and the second port is provided with a filtering structure.

[0013] The filter structure includes but is not limited to filter cloth, filter cotton, filter screen, chemical filter element, etc.

[0014] This solution can filter the liquid to prevent foreign matter from entering the equipment to be filled and causing abnormal operation of the equipment to be filled.

[0015] Preferably, the filtering structure comprises at least one of a Y-type filter and a filter screen.

[0016] This proposal recommends the specific structural form of the filtering structure.

[0017] Preferably, the number of filtering structures is greater than or equal to three.

[0018] This solution recommends a range of filter structure quantities, which is suitable for scenarios where the liquid is engine oil and can meet the filtering requirements of the three engine oil filters.

[0019] Preferably, a valve is provided on the delivery pipeline, and the valve is used to control the opening and closing or flow rate of the delivery pipeline.

[0020] The specific forms of valves include but are not limited to ball valves, diaphragm valves, plug valves, butterfly valves, etc.

[0021] This solution can facilitate operators to control the flow of liquid in the delivery pipeline, thereby controlling the filling progress of the liquid.

[0022] Preferably, a liquid level gauge is provided on the storage tank.

[0023] Specific forms of liquid level gauges include but are not limited to glass tube liquid level gauges, differential pressure liquid level gauges, float liquid level gauges, capacitance liquid level gauges, etc.

[0024] This solution can facilitate staff to observe the liquid level in the storage tank.

[0025] Preferably, the pump body comprises an explosion-proof self-priming pump.

[0026] This proposal recommends a specific structural form of the pump body that can meet the explosion-proof requirements of the gas well station.

[0027] Preferably, the width of the top of the filling port is greater than the width of the bottom of the filling port.

[0028] This solution makes the filling port larger at the top and smaller at the bottom, making it easier for workers to add liquid to the tank.

[0029] Preferably, a bracket is provided at the bottom of the storage tank, and the bracket is used to connect to the ground.

[0030] This solution can prevent the bottom of the storage tank from directly contacting the ground, prevent corrosion and cracking of the bottom of the storage tank, and make the storage tank stand more firmly on the ground.

[0031] In a second aspect, the present invention provides a gas compressor comprising a compressor body, to which a liquid filling auxiliary device of the present invention is connected.

[0032] The gas compressor of this solution is connected to the liquid filling auxiliary device of the present invention. When filling the engine oil, the staff does not need to carry the engine oil barrel to a high place first as in the existing solution. Instead, they only need to fill the liquid into the storage tank at a lower place and start the pump to complete the liquid filling operation. The filling process is convenient and fast, consumes less manpower, and there is no risk of the engine oil barrel and the staff falling from a height, which has higher safety.

[0033] Compared with the prior art, the present invention has the following beneficial effects:

[0034] 1. The utility model provides a liquid filling auxiliary device that connects the storage tank with the equipment to be filled through a conveying pipe. When liquid filling is required, the staff does not need to carry the oil barrel to a high place first as in the existing solution. Instead, they only need to fill the liquid into the storage tank at a lower place and start the pump to complete the liquid filling operation. The filling process is convenient and fast, consumes less manpower, and there is no risk of the oil barrel and the staff falling from a high altitude, which has higher safety.

[0035] 2. The utility model provides a gas compressor. By pre-connecting the liquid filling auxiliary device of the utility model to the compressor pump body, oil filling can be performed more quickly and conveniently, and the danger of the oil filling operation can be reduced.

Figure 2 As shown, the delivery pipe 2 is bifurcated into two branches at one end away from the first port, and the two branches are each provided with a second port at one end away from the first port, so as to connect two devices to be filled 3 respectively. In this way, liquid can be added to two devices to be filled 3 at one time, which has a higher filling efficiency. It should be noted that Figure 2The middle equipment to be filled 3 is located on the upper and lower sides of the storage tank 1 for the convenience of showing two parallel branches, but in fact the height of the two equipment to be filled 3 is not lower than the height of the filling port 11 on the storage tank 1.
