Description

Technical Field

[0001] The utility model relates to the technical field of lubrication equipment, in particular to a full-automatic centralized lubrication device for a beam pumping unit. Background Art

[0002] The lubrication system refers to a series of grease supply, grease discharge and its accessories that supply lubricants to the lubricated parts. The lubrication system can be divided into five types, namely, circulating lubrication system, centralized lubrication system, spray lubrication system, oil immersion and splash lubrication system, and total loss lubrication system of oil and grease.

[0003] There are some problems with the current lubrication device. First, it is difficult to achieve closed filling when grease is added by smearing method and grease is loaded into grease gun, which is very easy to be polluted by dust, water vapor, etc. Second, the old grease is squeezed out by smearing method or grease gun. The pumping unit needs about 5Kg of grease on average each time, but the actual lubrication is only a layer of oil film on the surface of the rotating part of the bearing, and the maintenance interval is 720 hours. It cannot be replaced in time after failure in operation, and the effective utilization rate of grease is low, which is seriously wasted. Third, the pumping unit should be maintained regularly according to the maintenance regulations. Since the equipment is scattered in the field, it is restricted by geographical and climatic conditions, and there are maintenance problems such as over-maintenance and missed maintenance. Fourth, the pumping unit needs to be operated at high altitude during maintenance, which is difficult to operate, with high safety risks and prone to falling and injuring people. Fifth, the traditional pumping unit needs to be shut down for maintenance. Each pumping unit needs about 20 hours of shutdown per year to fill grease, resulting in oil well production loss.

[0017] When using the fully automatic centralized lubrication device for the walking beam pump, first use a suitable refueling tool to add clean lubricating grease from the refueling port of the lubrication pump station 3. Loosen the oil inlet pipe joint of the distributor 5, and start the lubrication pump station 3 until clean grease is output from the pipe opening. Connect and tighten the oil inlet pipe joint of the distributor 5, and at the same time loosen the oil port joints of each lubrication point. Start the lubrication pump station 3 until grease flows out of each pipe opening. Connect and tighten each oil inlet pipe joint, and start the lubrication pump station 3. Observe the operating status of the lubrication pump station 3, check whether there is any leakage in each pipe joint, and deal with it in time. Start the lubrication pump station 3, and the lubrication system should be able to work normally according to the predetermined procedure. Turn off the power switch and the lubrication system stops working.

[0018] like Figure 1 As shown, as a preferred embodiment of the utility model, the lubrication pump station 3 includes: an electric pump 31, which is installed in the explosion-proof box 1, the electric pump 31 is connected to a microcomputer program controller 32 installed in the explosion-proof box 1, the microcomputer program controller 32 is connected to an oil tank 33 installed in the explosion-proof box 1, the oil tank 33 is used to store lubricating oil, the control panel 6 can control the start and stop of the electric pump 31, the electric pump 31 is used to control the opening and closing of the oil tank 33 through the microcomputer program controller 32; a pressure sensor 34, which is installed at the oil outlet of the oil tank 33, and is used to monitor the pressure of the lubricating oil.

[0019] The electric pump 31 can be started to control the opening and closing of the oil tank 33 through the microcomputer program controller 32. The oil tank 33 can be opened to pump out the lubricating oil from the oil pipe 4, so that it can be transported to various locations for lubrication through the distributor 5. The pressure sensor 34 can monitor the pumped-out pressure of the lubricating oil.

[0020] The grease in the oil tank 33 flows out from the pump outlet through the electric pump 31 and enters the distributor 5, and is supplied to the corresponding lubrication points of the oil pump through the pipeline by the distributor 5 (multiple outlets) according to the parameters set by the control system.

[0021] like Figure 3 As shown, as a preferred embodiment of the utility model, the control panel 6 includes: a panel body 61, which is installed in the explosion-proof box 1 and connected to the lubrication pump station 3, and the panel body 61 is provided with a working time display screen 62, an intermittent shutdown display screen 63, a low liquid level alarm 64, a password lock 65, a right key 66, an up key 67, a down key 68, and a left key 69.

[0022] When controlling the working time, press the up key 67 and the down key 68 simultaneously for more than three seconds, then the working time display screen 62 lights up and enters the working time adjustment state (Note: the maximum working time of the electric pump is 30 minutes); use the up key 67 and the down key 68 to adjust the first digit of the working time display screen (select between 0 and 3), after adjusting the first digit, press the right key 66 to adjust the second digit of the working time display screen 62, and use the up key 67 or the down key 68 to adjust the working time (select between 0 and 9). Since the maximum working time of the lubrication pump station 3 is 30 minutes, if the first digit is selected as 3, the second digit must be 0, indicating that the maximum working time is 30 minutes. The first digit of the minimum working time of this pump is 0, and the second digit is 1, indicating that the minimum working time of the lubrication pump station 3 is 1 minute.

[0023] When controlling the intermittent downtime, after adjusting the working time display screen 62, press the right key 66, then the intermittent downtime display screen 63 lights up, and enters the intermittent downtime adjustment state (Note: the maximum intermittent downtime of this pump is 24 hours), and the up key 67 or the down key 68 adjusts the first digit of the intermittent downtime display screen (select between 0 and 2), and after adjustment, press the right key 66 to adjust the second digit of the intermittent downtime display screen, and use the up key 67 or the down key 68 to adjust the intermittent downtime (select between 0 and 9).
