MOBILE VACUUM PUMP-COMPRESSOR PLANT OF CONTINUOUS ACTION Russian patent published in 2018 - IPC F04B47/02 F04B17/00 F04B23/02 

FIELD: engines and pumps.

SUBSTANCE: plant comprises of at least one main tank and three additional tanks disposed on a vehicle. It also includes a compressor, vacuum and slurry pumps driven by the vehicle's power plant, pipeline fittings for communicating pumps with tanks and a compressor. The main tank is made with two inlets, the first of which is communicated with the vacuum pump through a control unit. The second inlet is configured to communicate with the liquid medium and with one outlet - to communicate with the slurry pump. The additional tanks are made with two inlets, the first of which is communicated either with the vacuum pump or compressor through the control unit. The second inlet- with a sucked-in fluid and with one outlet - for emptying the tank from the fluid. Inlets and outlets of the main and additional tanks are equipped with check valves with the possibility of eliminating the reverse movement of the fluid. The control unit for each of the tanks has sensors of the minimum and maximum levels of the sucked-in fluid, located in these tanks. For the main tank, the control unit comprises of the first controlled valve for communicating the main tank with the vacuum pump, the second controlled valve for communicating the main tank and the vacuum pump to the atmosphere, and the third controlled valve for communicating this tank with the slurry pump for pumping out the fluid inside the main tank. These valves are connected to level sensors adapted to be controlled depending on the state of the fluid level. To control the filling and emptying modes of the additional tanks, the control unit is equipped with the fourth, fifth and sixth controlled valves for communicating the additional tanks with the vacuum pump adapted to be filled with fluid, as well as the seventh, eighth and ninth controlled valves for communicating the additional tanks with a compressor, which are adapted for the fluid displacement. The fourth, fifth and sixth controlled valves are switched to the "closed" mode.

EFFECT: performance and reliability are increased, it is possible to collect and pump mixtures of high viscosity with increased content of mechanical impurities at long distances, great depths and continuous filing over long distances using vacuum.
