DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0023] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0024] like Figure 1-3 As shown, an electric lubrication pump system provided by an embodiment of the utility model includes:

[0025] Grease power station part, the grease power station part includes:

[0026] An oil storage tank, used to store grease and supply grease to the oil filling pump;

[0027] The motor 12 and the oil injection pump, there are two oil injection pumps (No. 1 oil injection pump 131 and No. 2 oil injection pump 132), the two oil injection pumps work independently, and transmit the grease in the corresponding oil storage tank to the main oil pipe 02 at high pressure; the motor 12 of the oil injection pump is fixed on the connecting flange with the pump element, and drives the sliding fork 1315 to perform linear reciprocating motion by driving the eccentric shaft;

[0028] Two groups of pistons are arranged in the pump body 1310 of the oil injection pump, and each group of pistons includes a working piston 1311 and a control piston 1312. The working piston 1311 and the control piston 1312 both reciprocate in the horizontal direction in the pump body 1310, and the control piston 1312 controls the suction and discharge of grease by working with the working piston 1311; a guide rod 1313 is fixedly connected to the pump body 1310; the oil injection pump includes a spring, a sliding fork 1315 and a push rod 1314, the working piston 1311 is connected to the sliding fork 1315, the sliding fork 1315 moves in the pump body 1310 along the guide rod 1313, and the push rod 1314 is used to push the control piston 1312.

[0029] Safety valve 14;

[0030] The pressure gauge 15 is used to reflect the pressure of the oil outlet of the pipeline;

[0031] A main pipeline system part, one end of which is connected to the oil injection pump;

[0032] Sub-pipeline system part;

[0033] Distributor 05, the other end of the main pipeline system is connected to one end of the distributor 05, and the other end of the distributor 05 is connected to the branch pipeline system; the distributor 05 is used to distribute the grease discharged by the oil injection pump from the main pipeline system to the branch pipeline system;

[0034] Automatic pipe retractor 06 is used to automatically control the retraction of the pipeline.

[0035] In the embodiment of the utility model, when the working piston 1311 in one group of pistons completes the oil suction process, the working piston 1311 in the other group of pistons presses the grease toward the oil outlet. Figure 2As shown, when the sliding fork 1315 moves to the left, the upper piston group completes oil suction, and the lower piston group completes oil compression, and a new working cycle begins. At this time, the working piston 1311 and the control piston 1312 of the lower piston group move to the left. The control piston 1312 reaches the limit position under the action of the spring force and closes the outlet, while the working piston 1311 continues to move to the left. At this time, a vacuum is formed between the control piston 1312 and the working piston 1311, and its vacuum degree increases continuously as the working piston 1311 moves to the left. When the sliding fork 1315 moves to the limit position, the working piston 1311 opens the oil suction port, and the grease is sucked from the oil suction port. If the spring force is insufficient and the control piston 1312 is not pushed to the limit position, the push rod 13143 will be at the sliding fork 1315. Under the push of, piston 2 is forced to the limit position. At the same time, the working piston 1311, the control piston 1312 and the push rod 13143 of the upper group of pistons move to the left. The working piston 1311 closes the oil suction port first, and the sucked grease moves to the left under the push of the working piston 1311. When the working piston 1311 and the control piston 1312 contact the sliding fork 1315 and have also moved to the limit position, half a cycle of work is completed. This cycle is repeated over and over again. The two groups of pistons alternately send the grease out of the oil outlet, and the squeezed grease is filtered by the filter on the flange with the pump element and then supplied to the system.

[0036] like Figure 1 As shown, as a preferred embodiment of the utility model, there are two oil tanks (No. 1 oil tank 111 and No. 2 oil tank 112), which store marine grease respectively, and the capacity of each is 60L. The oil tank supplies oil to the oil filling pump by mechanical twisting. The lower side of the oil tank is equipped with a refueling port, which is mainly used to add grease to the oil tank through an electric refueling pump. The cover on the top of the oil tank is mainly used to facilitate the cleaning of debris in the oil tank, and is not used to add grease. Grease in the oil tank must be injected from the refueling port with an electric refueling pump to avoid the grease from being compressed normally due to air entering the lubrication pump.

[0037] like Figure 1 As shown, as a preferred embodiment of the utility model, the safety valve 14 is an adjustable relief valve. When the oil pressure in the pipeline reaches or exceeds the opening pressure of the safety valve 14, the safety valve 14 will work to make the grease flow back to the oil storage tank to prevent the oil pressure in the pipeline from being too high, thereby ensuring the safety of the system. The safety valve 14 is adjusted by slowly rotating the adjusting bolt, and the pressure can be adjusted to the required pressure value by observing the pressure gauge 15.

[0038] like Figure 1 As shown, as a preferred embodiment of the utility model, the main pipeline system part includes two main oil pipes 02 and joints 04. The joints 04 at both ends of the main oil pipes 02 connect the main oil pipes 02 to the oil outlet joints 04 and the distributor 05 of the oil injection pump respectively.

[0039] like Figure 1 As shown in the figure, as a preferred embodiment of the utility model, the branch pipeline system is equipped with four oil distribution pipes 31, each of which is connected by two sections. The end of the oil distribution pipe 31 is equipped with a switch ball valve 32, and the two ends of the oil distribution pipe 31 are equipped with joints 04. The joints 04 at both ends of the oil distribution pipe 31 connect the oil distribution pipe 31 to the distributor 05 and the fuel nozzle of the submarine respectively. During operation, a single oil distribution pipe 31 can work, or two oil distribution pipes 31 can work at the same time.

[0040] like Figure 1 As shown, as a preferred embodiment of the utility model, the switch ball valve 32 includes a ball valve and a pressure relief valve. In daily use, the ball valve is normally open and the pressure relief valve is normally closed. When replacing the oil gun, there is pressure in the pipe. It is necessary to close the ball valve at the outlet. After opening the pressure relief valve, the end pressure is discharged from the pipeline before the oil gun can be replaced. After turning off the main power switch, the oil injection pump stops working. At this time, the pipe unloading operation cannot be performed, and there is high pressure in the pipe. The pipe unloading operation is performed after the oil pressure in the pipe is released by closing the ball valve and opening the pressure relief valve.

[0041] like Figure 1 As shown in the figure, as a preferred embodiment of the utility model, the distributor 05 adopts one oil inlet and two oil outlets. There are two distributors 05 in total, and the two distributors 05 respectively distribute the grease discharged from the corresponding oil injection pumps from the main oil pipe 02 to each oil branch pipe 31. The distributor 05 is provided with two valves, which are used to adjust the pressure balance of the two oil outlets of the distributor 05.

[0042] like Figure 1 and Figure 3 As shown, as a preferred embodiment of the present invention, the automatic tube collecting machine 06 includes a gear reduction motor and a frequency conversion controller.

[0043] Embodiment 1: A working method of an electric lubrication pump system provided in one embodiment of the utility model comprises the following steps:

[0044] Step 1. Preparation before work:

[0045] 11. Check the grease: Park the mobile transport vehicle on a relatively flat place, pull up the handbrake of the transport vehicle or fix the wheels of the transport vehicle to prevent the transport vehicle from sliding during use. Open the doors of all parties and check whether the oil level in the oil storage tank is sufficient. If the oil level is insufficient, add lubricating oil in an emergency to avoid air entering the oil filling pump and damaging the oil filling pump.

[0046] 12. Grease replenishment process of the oil tank: When the oil in the oil tank is insufficient, grease must be replenished. When replenishing, pay attention to the cleanliness of the grease. No large particles of debris are allowed in the grease to avoid clogging the oil filling pump. Fix the inlet of the replenishing grease pump on the oil barrel, connect the outlet to the refueling port of the oil filling pump, and connect the power cord to the 380V socket in the cabin to complete the grease replenishment process.

[0047] 13. Connection of pipelines: Connect the main oil pipe 02, distributor 05, and oil distribution pipe 31 in sequence, and check that each connection is secure. When connecting the pipelines, select the oil pipe and distributor 05 according to the type of grease to be added, and finally connect the switch ball valve 32 to the end of the oil distribution pipe 31.

[0048] 14. Circuit connection: Before connection, check whether the main switch of the electric control box is in the off state, and then connect the power cord to the 380V power supply.

[0049] 15. Pressure test adjustment: After the pipeline is connected (the oil nozzle is not connected), close each switch ball valve 32, then close the main switch and the start switch button, and wait for one minute. Slowly adjust the pressure regulating valve (i.e., safety valve 14) to about 20MPa (generally, the pressure is adjusted at the factory. If the pressure is not released through the full-valve normally, there is no need to readjust the safety valve 14). Wait for about 2 minutes to see if there are any abnormalities in the entire system. If no abnormalities are found, connect the end connector 04 of the oil distribution pipe 31 to the oil nozzle of the submarine to add grease (if the pipeline is not originally full of grease, wait until the pipeline is full of grease, then close each switch ball valve 32, and then proceed according to step 15).

[0050] 16. Connection of the oil filling nozzle: First select the corresponding connection joint 04 from the tool box and connect it to the oil filling nozzle of the required grease filling equipment, then connect the joint 04 at the end of the oil distribution pipe 31 with the connection joint 04, and the grease can be filled by controlling the switch ball valve 32. It should be noted that when the connection joint 04 of the oil filling nozzle part and the end joint 04 of the pipeline are connected, the switch ball valve 32 must be in the closed state.

[0051] Step 2: Oil filling process:

[0052] 21. When the preparations before work are completed, turn on the main power switch and check whether the phase sequence indicator light is on. If the indicator light is on, turn the phase sequence conversion switch to change the phase.

[0053] 22. Press the start button of Pump 1 (or Pump 2), the oil injection pump begins to lubricate and compress the grease, and the oil pressure rises (the first time it is used, there is no oil in the pipeline, so the increase will be slow).

[0054] 23. When the pressure is stored in the pipe, just open the switch of the switch ball valve 32 at the end to add grease to the lubrication part of the equipment.

[0055] 24. When refueling, because grease is delivered in a progressive manner, pressure is generated only when back pressure is generated, and the oil pressure increases with the back pressure. Therefore, attention should be paid to the filling of grease when refueling. After filling, the switch ball valve 32 must be closed in time, otherwise the back pressure will continue to increase after the grease is pressurized, which may damage the lubrication pipeline and equipment on the equipment.

[0056] 25. During use, due to the oil pressure in the pipeline, when switching from one fueling nozzle to another for refueling, the switch ball valve 32 must be closed first and then the connection and installation of each connector 04 must be carried out.

[0057] 26. Check the oil level in the oil storage tank regularly. If the oil level is insufficient, stop the machine immediately and add lubricating grease.

[0058] 27. Before oiling, fill the required oiling equipment with grease and connect the overflow port to the oil return port of the oil filling pump for the recovery of the spilled oil (this operation can be omitted when the amount of oil filled is small).

[0059] Step 3, oil filling is completed;

[0060] 31. Press the stop button of pump 1 (or pump 2), turn off the main power switch, and the oil injection pump stops working; the pipe unloading operation cannot be performed at this time, and there is high pressure in the pipe.

[0061] 32. Release the oil pressure in the pipe through the safety valve 14 or the switch ball valve 32 at the end of the pipeline.

[0062] 33. Remove the power cord and wind it neatly on the cable reel.

[0063] 34. Disassemble the oil filling pipeline, clean the connector 04 on each hose with a rag after refueling and store it in the tool box, then wind the hose neatly on the pipe reel.

[0064] 35. Use a cloth to clean the pipe connectors 04, the oil nozzles, and the distributors 05, and store them in the tool box.

[0065] The above are only preferred implementations of the present invention. It should be pointed out that, for those skilled in the art, several modifications and improvements can be made without departing from the concept of the present invention. These should also be regarded as the protection scope of the present invention. These will not affect the effect of the implementation of the present invention and the practicality of the patent.
