Description
Technical Field
The utility model relates to a lubricated equipment technical field specifically is a double-line type centralized lubrication system.
Background
The centralized lubricating system is a main auxiliary device of the blast furnace top, and provides timing lubrication for the main part of the blast furnace top device, thereby reducing the abrasion of the blast furnace top device and prolonging the service life. The centralized lubrication overcomes the defects of the traditional manual lubrication, and can provide lubrication at regular time, fixed point and fixed quantity when the machine operates, so that the abrasion of mechanical equipment is reduced to the minimum, and the using amount of lubricating oil can be reduced.
The centralized lubrication system mainly adopts double-wire centralized lubrication, and the double-wire centralized lubrication system enables the lubricating oil to pass through the two-position four-way reversing valve and the oil supply pipeline and then pass through the distributor, so that the required lubricating oil is accurately supplied to a plurality of lubricating points according to a certain time. However, the conventional lubricating system uses a distributor, the oil output of each outlet of the distributor is the same, and for equipment with different oil amounts, the oil amount of the equipment is too much or too little, so that the oil is wasted; and too much oil is accumulated on the equipment, and equipment accidents can be caused.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is: the technical problem that the traditional double-line centralized lubricating system cannot meet the oil quantity required by all furnace top equipment is solved.
The utility model provides a double-line centralized lubrication system, which comprises an oil tank and a controller; the oil tank is provided with an electric lubricating pump, the outlet of the electric lubricating pump is provided with a dry oil filter, an overhaul ball valve and a two-position four-way reversing valve which are sequentially connected through pipelines, the two-position four-way reversing valve is provided with two branches, and each branch is provided with a distributor and a second pressure reading and transmitting device;
a first pressure reading and transmitting device and a safety valve are arranged between the dry oil filter and the service ball valve;
the controller is electrically connected with the two-position four-way reversing valve; the controller is electrically connected with the first pressure reading and transmitting device and is provided with a first alarm; the controller is electrically connected with the second pressure reading and transmitting device and is provided with a second alarm.
The pressure reading and transmitting device can accurately measure and display the oil pressure in the pipeline and transmit the pressure value to the controller. When the electric lubricating pump works, lubricating oil is pumped out of the oil tank, is filtered by the dry oil filter to supply oil to the main oil way, and then flows into one branch, when the pressure value displayed on the second pressure reading and transmitting device on the branch reaches the set pressure value, the electric lubricating pump stops working, and after the equipment lubrication is finished, the controller controls the two-position four-way reversing valve to reverse and supply oil to the other branch; two different distributors provide different oil output, the effectual demand that has satisfied each lubricating point to the lubricated volume of rational distribution prevents that lubricating oil is too much or too little, has alleviateed the intensity of labour of operative employee's clearance waste oil. When the pressure value displayed on the first pressure reading and transmitting device exceeds a set value, the controller can control the first alarm to give out an alarm and release pressure through the safety valve; after a period of working, when the pressure value displayed on the second pressure reading and conveying device is smaller than a set value, the controller can control the second alarm to give an alarm to prompt workers that the oil way leaks oil and needs to be overhauled in time.
Further, the oil tank is provided with a low liquid level alarm, and the low liquid level alarm is electrically connected with the controller. When the lubricating oil liquid level in the oil tank is lower than a set value, the controller controls the low liquid level alarm to give an alarm to prompt that the lubricating oil in the oil tank is too little and the lubricating oil needs to be added.
