Description

The utility model relates to the field of transport engineering, in particular to the maintenance process equipment of the vehicle maintenance areas, and is intended for lubrication of the rubbing parts of the vehicle, tractors and other machines through motor nipples in motor transport enterprises and service stations.

Known lubricating supercharger with a spring energy accumulator (RF patent No. 2511794, publ. 04/10/2014), is additionally equipped with a spring energy accumulator, as well as a tip with an exhaust valve. Charging and recharging the energy accumulator is carried out by a jack. Lubrication in the grease nipple - with the force of the tip on it. Together, this allows you to create a simple and compact design of a grease blower. In addition, a spring manometer is arranged in the supercharger design, which makes it possible to control the lubricant pressure in the cylinder cavity.

The disadvantage of this device is that it is difficult and time-consuming to operate.

Known automatic discharge device of highly viscous materials (RF patent No. 2499947, publ. 11/27/2013), is a supercharger in which natural gas (air) under pressure acts on a pneumatic actuator piston, the rod of which is connected to the pump plunger and interacts with the operational material, forcing it along the high pressure sleeve into the packing units of shut-off and control valves or other equipment.

The disadvantage of this device is that the principle of its operation is based on the supply of compressed air from the compressor unit to the pneumatic drive, in the absence or failure of which the device stops working.

A device for supplying lubricant is known (RF patent No. 224202, publ. 10.01.2005), comprising a housing with a plunger and a check valve, a cylinder with a piston and a rod, characterized in that the device is equipped with a universal stand, and is made on the rod and in the cover thread for moving the piston.

The disadvantage of this device is that when working with it it is very time-consuming and inconvenient due to the fact that it is necessary to fix the oil supply nipple and pump the oil mechanically (handle). Use a small amount of lubricant.

A hydromechanical device for lubricating vehicles with grease is known (RF patent No. 2119609, September 27, 1998) containing a hopper, a lubricating supercharger in the form of a pressure multiplier with a hose, connecting pipelines, a control valve, an articulated bridge with a latch and a stop.

The disadvantage of this device is that the lubricating device is driven by the weight of the vehicle, has a complex structure based on hydromechanical force.

Known supercharger lubricant garage model C322M (technical data sheet), adopted as a prototype, the main components of the supercharger are: a lubricant tank, a screw for supplying lubricant to the pump, a pressure switch, a control unit, a gearbox, a cart, a gun with a flexible sleeve, a handle for transportation supercharger, electric motor, special bolt for air discharge.

The disadvantage of this device is the design complexity: to service the coarse filter, disassembly is required, it requires a socket in the working area for connection with an operating voltage of 380 V, the simultaneous use of only one dispensing device "a gun with a flexible hose", a tank of limited volume.

The technical result is to increase the reliability and efficiency of the device and simplify the design.

The technical result is achieved by the fact that the device is additionally equipped with a backup control valve, which is mounted to the inlet flange through a threaded connection, a lubricant accumulator and points for connecting oil dispensing guns, a rough filter is installed and connected to the outlet flange by a high pressure sleeve, the ends of which are fixed with a coupling metal clamps.

The installation is illustrated by the following figures:

The grease supply unit consists of: (Fig. 1) a container 1, consisting of a metal housing 2 with a lockable cover 3. At the base (bottom) of the container 1 there is a flange 8 for connecting a high-pressure supply sleeve, a pipe 10 (Fig. 2 ) and a screw pump 4 made of steel is installed, driven by an electric motor 5, connected to a reducer 6 (the gears of which are made of steel located in an aluminum case) through a rubber coupling 9. Capacity 1, a screw pump 4, an electric power plant the electric motor 5, the gearbox 6 are rigidly bolted to a metal support stand 7.

A rubber connecting pipe 10 is attached to the pump outlet to the flange 8 (Fig. 2), the second end of which is attached to the inlet flange of the coarse filter cassette 11, which consists of metal ones: the casing 12 with the inlet and outlet flanges, the cover 13, which is tightly bolted to the casing, cassette filter 14, made in the form of a grid. A backup control valve 16 (turning off the power plant electric motor 5) is attached to the input flange through a threaded connection. A connecting rubber pipe 15 is connected to the output pipe, which is connected to the storage battery (Fig. 3). The nozzles 10 and 15 are attached to the flanges by means of coupling metal clamps.

In the metal accumulator 17 (Fig. 3) there are: an inlet flange, to which a nozzle 15 is attached, to which a control valve 18 is attached through a threaded connection, which allows regulating the pressure in the accumulator, points with quick-disconnect nipples 19 for connecting the guns of the superchargers 20, connected by flexible hose 21.

The installation works as follows: the lubricant from the tank 1 is pumped by a screw pump 4, driven by the power plant of the electric motor 5, through the gearbox 6 to the drive 17, passing through the connecting pipes 10, 15 and the coarse cartridge filter 11. Blowers 20, in in turn, they are connected to the lubrication point of the serviced node, connecting to the drive 17 through the connection points (quick disconnect nipples) 19. The control valves 16 and 18 of the power plant of the electric motor 5 allow control the pressure in the accumulator 17 and prevent the installation from damage and its failure.

The grease supply unit, thanks to a separately located and easily serviced coarse filter cartridge, makes it possible to work with several dispensing guns at once, as well as its compact design and placement of the battery, which saves space in the working area.
