The utility model is characterized in that the self-controlled jetting lubricating pump also comprises an automatic cycle controller which can supply air and oil at definite times. The automatic cycle controller is composed of a timing cycle timing relay SJ< 1 >, an air supplying timing relay SJ< 2 >, an oil pump working timing relay SJ< 3 >, two electromagnetic valve auxiliary relays Z< 1 >, Z< 2 >, and a main alternating current contactor QC. The utility model is provided with an indicating lamp, can visually display the working state, and has the advantages of reasonable structure, safe and convenient operation, low cost, reliable performance, long service life, etc.
Description
The utility model belongs to the lubricating utensil technical field, specifically a kind of lubricating fitting to main equipment.
As everyone knows, open type transmission positions such as the gear in heavy mining machinery, cogeneration power plant Steel Ball Coal Mill and large-scale transmission device, sprocket wheel need frequent oiling to guarantee the lubricated of this equipment.But present general lubrication oiling apparatus, the poor reliability that is in operation, and control circuit complexity, working state does not show intuitively, when misoperation, can't in time correct, strengthen the degree of wear when equipment is operated, even the serious accident of device damage can occur.In addition, existing lubricating fitting does not also guarantee the time-delay air feed of air feed system, comes the remaining lubricant oil of washer jet, and influences the carrying out of next working procedure.
The purpose of this utility model provide a kind of can be regularly, quantitatively spray lubricant oil and have the automatic control jet lubrication pump of display working condition directly perceived to lubricated position.
The purpose of this utility model is achieved in that it includes a fuel tank with oily temperature and oil level demonstration, above fuel tank, be provided with and water be housed in one from separator, pressure regulator valve, solenoid valve, motor, the transparent supporting cover of gear pump, it is characterized in that also comprising one by the time delay relay SJ1 that regularly circulates, air feed time delay relay SJ2, oil pump work time delay relay SJ3, solenoid valve auxiliary reclay Z1, timing air feed and fuel feeding automatic cycle controller that Z2 and main A.C. contactor QC constitute, the normally-closed contact of time delay relay SJ1 and auxiliary reclay Z2 of regularly circulating is in series, the normally closed Time Delay Opening contact and the auxiliary reclay Z1 that often open timing closing contact and air feed time delay relay SJ2 of time delay relay of regularly circulating is in series, air feed time delay relay SJ2 and solenoid valve and auxiliary reclay Z1 are in parallel, and main A.C. contactor QC and oil pump work time delay relay SJ3 be logical to be closed the back that is in series, Time Delay Opening contact and be in parallel with above-mentioned auxiliary reclay SJ1.
Therefore the utility model has following advantage owing to adopted above-mentioned control circuit:
(1) adopted the New J SM8 series of pulses time relay, this relay reliable operation, and itself have tutorial light, can show its working state intuitively.Also guaranteed the mutual restriction of each relay in addition in control circuit, if next relay can not execution work, other relay can not worked yet, to make the utility model under operation automatically periodically periodic duty be guaranteed.
(2) when adopting above-mentioned new type of relay, LM8363 type digital display timer and tutorial light have also been installed additional, make entire work process all have work light indication and time to show, can intuitively find out if any fault, be convenient to timely eliminating, guarantee working properly reliably, and that link also can be found out on operating table intuitively in work.
(3) the utility model also has advantages such as rational in infrastructure, easy-to-operate, cost are low, reliable performance, long service life.
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 is the utility model circuit theory diagrams
Fig. 2 is the utility model appearance structure schematic representation
With reference to the accompanying drawings 1,2, the utility model includes a fuel tank 1 with oily temperature and oil level demonstration, above fuel tank 1, also be provided with the transparent supporting cover 2 of water from separator, pressure regulator valve, solenoid valve DF, motor, gear pump is housed in one, be provided with an automatic draining air tube valve that links to each other from separator with water in the side of transparent supporting cover, and the timing air feed and the fuel feeding automatic cycle controller that constitute by regularly circulate time delay relay SJ1, air feed time delay relay SJ2, oil pump work time delay relay SJ3, solenoid valve auxiliary reclay Z1, Z2 and main A.C. contactor QC.Its working principle is: when pressing air recloser DZ, the time delay relay SJ1 that regularly circulates gets, after delaying time (this time is circulation time) in 2 hours, it often opens the timing closing make contact, auxiliary reclay Z1, air feed time delay relay SJ2, oil pump work time delay relay SJ3, auxiliary reclay Z2, solenoid valve DF and main A.C. contactor QC adhesive, after oil pump work a period of time (about 60 seconds), open the logical Time Delay Opening contact of closing of oil pump work time delay relay SJ3, the work of oil pump stop, and this moment, air feed solenoid valve YV worked on a period of time, purpose is the long-pending oil of clearing away in the nozzle, guarantees nozzles clear.After air feed time delay relay SJ2 delay time (about 65 seconds) finished, opened its normally closed Time Delay Opening contact, makes the Z1 dead electricity.So far one-period finishes, and following task is treated to open automatically after SJ1 delayed time 2 hours and made.Above-mentioned timing circulation time delay relay SJ1, solenoid valve and main A.C. contactor two be auspicious to be connected with timing indicator ZD1, air feed tutorial light ZD2 respectively and lamp ZD3 is shown in oil pump work.Timing display device SZ1, air feed operating time display device SZ2 and oil pump operating time display device SZ3 also can be set in addition, and timing display device SZ1 and air feed operating time display device SZ2 are in series with normally-closed contact and the normally opened contact of above-mentioned auxiliary reclay Z2 respectively.Above-mentioned timing circulation time delay relay, air feed time delay relay and oil pump work time delay relay all adopt the JSM8 impulse timer.And timing display device SZ1, air feed operating time display device SZ2 and oil pump operating time display device SZ3 adopt LM8363 type digital display timer.
