AnUVM device.

ANUVM is a supercharger in which natural gas (air) under pressure acts on the piston of a pneumatic actuator, the rod of which is connected to the pump plunger and interacts with the operating material, pumping it along the high pressure sleeve into the packing units of shut-off and control valves or other equipment.

ANUVM (figure 1) consists of a plunger pump 2, a pneumatic drive 1, a refueling tank 3 and a set of connecting equipment mounted on a trolley.

The plunger pump 2 is designed for injection of operating materials under pressure into the packing units and consists of a housing, a rod, a seal assembly, a suction, discharge and relief valves, a plunger lubrication assembly.

Pressure and suction valves are similar in design and are two seat ball valves. The suction valve is attached to the pump casing on one side and inserted into the opening of the filling tank on the other side. The discharge valve is attached to the pump casing on one side, and a relief valve is built into the pressure casing on the other hand.

The relief valve is designed to relieve pressure from the high pressure sleeve, as well as to remove air from the working chamber of the pump.

Pneumatic actuator 1 is designed to convert the energy of compressed gas (air) into the translational movement of the piston of a pneumatic cylinder and the impact through it on the piston rod of the pump.

The pneumatic actuator 1 consists of a pneumatic cylinder and a gas (air) distribution unit.

The basis of the pneumatic drive 1 is a pneumatic cylinder, which in connection with a plunger pump 2 is attached to the filling tank 3.

The distribution unit ensures the operation of the pneumatic cylinder and the refueling tank 3. It consists of a pneumatic distributor, two exhaust throttles, two cylinder position sensors, a manifold, a pressure regulating filter, a shut-off valve, connecting hoses and connecting fittings. The cylinder position sensors are fixed in the supply holes of the pneumatic cylinder and are designed for non-contact generation of a pneumatic signal at the end of the piston stroke of the cylinder. To connect the ANUVM to the power source, an input quick-disconnect plug is used, which is screwed into the collector.

The refueling tank 3 is designed to store operational material and ensure its uninterrupted supply to the working chamber of the plunger pump. It is a cylinder with a floating type piston and a removable cover. On one side, a fitting for connecting a pneumatic hose is screwed into the cylinder of the filling tank. The lid closes the neck of the filling tank and is attached to the cylinder of the tank on four studs with nuts. A quick-disconnect plug is screwed into the cover to return the piston of the fuel tank to its original position and a fitting with a safety plug.

The filling tank 3 is connected through the suction valve to the plunger pump 2, and through the connecting hose to the pneumatic drive manifold 1. The cylinder piston of the filling tank is equipped with permanent magnets, and a measuring scale is built into the groove of the aluminum cylinder, the pointer of which can move after the cylinder piston.

The connecting equipment is intended for: supplying natural gas (air) with a given working pressure to the ANUVM; purification of natural gas (air) from mechanical impurities and moisture; supply of operational material from the plunger pump to the packing units; moving the piston of the refueling tank to its original position before refueling with its operational material.

The connecting equipment consists of a gearbox, a filter regulator, an oil nebulizer, a pneumatic hose with a quick-detachable plug, a quick-detachable socket, a high-pressure hose with an adapter.

The reducer provides a reduction in the pressure of natural gas (air) from the power source to the ANUVM to 0.8 MPa. To connect the gearbox to the gas (air) tap, a fitting with an M20 × 1.5 thread is used.

The filter-regulator cleans natural gas (air) from mechanical impurities and moisture, provides control of the gas (air) pressure supplied through the oil atomizer to the entrance to the ANUVM. A quick-release socket for connecting a pneumatic hose is attached to the input of the filter regulator.

The oil atomizer is connected to the filter regulator in a single unit and enriches natural gas (air) with oil to increase the durability of the sealing elements of the pneumatic actuator 1 and the filling tank 3.

A fitting for connecting a connecting hose with a quick-release socket, which, in turn, connects to the quick-disconnect plug of the manifold or to the quick-disconnect plug of the refueling tank 3, is screwed into the oil spray from the output side.

The high-pressure hose is connected at one end to the threaded fitting of the plunger pump 2, and at the other end, through the adapter, to the fitting of the lubrication unit of the stop valve.

Pneumatic drive 1, refueling tank 3 and a set of connecting equipment are assembled on components of the Austrian-German concern FESTO (see the FESTO product catalog, version 2009/2010).

Work ANUVM.

Pneumohydraulic circuit ANUVM shown in figure 2.

The principle of operation of the ANUVM in terms of creating high pressure is based on the ratio of the piston areas of the pneumatic cylinder 11 and the piston rod of the pump 10. In this device, this ratio is 61.

Natural gas (air) from the power source through the selection valve 25 is supplied to the pressure reducer 24, where its pressure drops to 0.8 MPa, and then through the pneumatic hose 23 it enters the filter regulator 4. In the filter regulator 4, natural gas (air ) is cleaned of mechanical impurities and moisture, enters the oil nebulizer 5, which enriches natural gas (air) with oil.

Further, through a connecting hose using a quick disconnect connection 21, consisting of a socket and a plug, natural gas (air) enters the manifold 22, where it is divided into three streams.

The first stream enters through the air distributor 18 into the pneumatic cylinder 11, where it acts on the piston and moves it. The piston, moving in the direction of the cavity "E", carries along the stem of the plunger pump 10, which, freeing the working cavity "C", creates a vacuum in it. Under the influence of vacuum, the operating material through the suction valve 12 enters the working cavity "C" from the refueling tank 14.

The second stream enters the position sensors of the cylinder 19, 20 and controls the operation of the pneumatic valve 18.

The third stream enters through the nozzle into the cylinder of the refueling tank 14 and acts on its piston. The piston, moving, squeezes the operating material from the refueling tank 14 into the suction valve 12 and further into the working cavity of the plunger pump 10.

Changing the direction of movement of the piston of the pneumatic cylinder 11 is provided by the position sensors of the cylinder 19, 20.

When the cylinder piston moves in the direction of the "D" cavity: natural gas (air) is discharged from this cylinder cavity through the channel 4-5 of the air distributor 18 and the exhaust throttle 17 into the atmosphere; operating material, moving under pressure, closes the suction valve 12, preventing it from entering the cavity "B" of the refueling tank 14; the operating material opens the discharge valve 6 and flows under pressure into the high pressure sleeve 9 and then to the fitting of the lubrication unit of the stop valve.

Upon reaching the piston of the pneumatic cylinder 11 of the extreme left position (in accordance with figure 2) at the input 10 of the position sensor of the cylinder 20, the signal disappears due to the pressure drop in the cavity "D" of the pneumatic cylinder 11 and the passage opens from channel 1 of the sensor 20 to channel 2. Pilot air from channel 2 of the sensor 20 enters the input 14 of the air distributor 18 and switches its valve, as a result of which the channels 4-5, 2-1 of the air distributor are closed and the channels 4-1, 2-3 open. Under the influence of the vacuum in the working cavity "C" of the plunger pump 10 and the pressure of the operating material in the high pressure sleeve 9, the discharge valve 6 closes. Moreover, under the influence of the pressure of the operating material from the cavity "B" of the filling tank 14 and the vacuum in the working cavity "C" of the plunger pump 10, the suction valve 12 opens. The operational material comes from the cavity "B" of the filling tank 14 into the working cavity "C" of the plunger pump 10 and fills it.

Upon reaching the piston of the pneumatic cylinder 11 of the extreme right position at the input 10 of the position sensor of the cylinder 19, the signal disappears due to the pressure drop in the cavity "E" of the pneumatic cylinder 11 and the passage opens from the channel 1 of the sensor 19 to the channel 2. Pilot air from the channel 2 of the sensor 19 enters the input 12 of the valve 18 and switches its valve, as a result of which the channels 4-1, 2-3 of the valve are closed and the channels 4-5, 2-1 open. The operation cycle of the ANUM is repeated.

To relieve pressure from the high pressure sleeve 9 or to remove air from the working cavity of the plunger pump 10, it is necessary to turn the screw of the relief valve 0.5-1 turn. When moving the screw, the ball of the valve moves away from its seat under high pressure and the pressure is released into the atmosphere.

To move the piston of the refueling container 14 to its initial position with the purpose of refueling it with operating material, it is necessary to disconnect the quick-release socket of the connecting hose connected to the quick-disconnect plug of the manifold (quick-connect 21) and connect it to the quick-disconnect plug 13 of the refueling container 14. After moving the piston of the refueling tank 14 In the initial position, you must connect the connecting hose to the quick connector of the manifold.

The change in the speed of movement of the piston of the pneumatic cylinder 11 is carried out by a shut-off valve 16 with manual control, which has two operating modes: forward flow and throttling. The piston displacement speed is controlled by changing the flow rate of natural gas (air) discharged from the pneumatic cylinder 11 through exhaust throttles 17 equipped with integrated silencers into the atmosphere.
