Поршневые насосы нашли широкое применение в системах смазок горных машин. При проведении технического обслуживании (ТО), включая смазочно-заправочные работы, на месте эксплуатации горных машин из-за удаленности от ремонтных цехов и складов горюче-смазочных материалов (ГСМ) применяют передвижные ремонтные мастерские (ПРМ), агрегаты технического обслуживания (АТО) и механизированные заправочные агрегаты (МЗА). Специфика проведения ТО заключается в создании условий для подачи масел, рабочих жидкостей и смазок в соответствующие системы горных машин для их заправки. Существующие поршневые насосы и насосные агрегаты, как правило, однопоточны, а привод поршня осуществляется кривошипно-шатунным механизмом, приводимым в движение от двигателя через червячный редуктор. Появление на открытых горных работах уникальных, гидрофицированных, маломобильных горных машин потребовало значительно повысить мощность маслоподающих насосных агрегатов АТО и МЗА, в первую очередь для консистентных смазок. Однако традиционная схема конструкций привода поршневого насосного агрегата кривошипного типа при мощностях свыше 80 кВт не позволяет достигать заданной наработки, сопровождается интенсивным износом элементов привода и увеличенной динамикой при работе. Кроме того, необходимо применять различные конструкции насосных агрегатов для подачи жидких и консистентных смазок. Таким образом, необходима разработка новых схемных решений насосных агрегатов кривошипного типа, совершенствования мобильных средств заправки с модернизированной конструкцией привода насосного агрегата мобильной смазочно-заправочной установки ПРМ.

Piston pumps are widely used in the lubrication systems of mining machines. When carrying out technical maintenance (MOT), including lubrication and filling works, at the site of operation of mining machines due to the remoteness from repair shops and warehouses of fuels and lubricants (FAL), mobile repair shops (MRS), maintenance units (MU) and mechanized filling units (MFU) are used. The specificity of carrying out maintenance is to create conditions for the supply of oils, working fluids and lubricants to the corresponding systems of mining machines for their refueling. Existing piston pumps and pumping units, as a rule, are single-flow, and the piston is driven by a crank mechanism driven from the engine through a worm gear. The emergence of unique, hydraulic, low-mobility mining machines in open pit mining required a significant increase in the power of the MU and MFU oil pumping units, primarily for greases. However, the traditional design of the drive design of a crank-type piston pump unit at a power of over 80 kW does not allow achieving the specified operating time, it is accompanied by intensive wear of the drive elements and increased dynamics during operation. In addition, it is necessary to apply various designs of pumping units for the supply of liquid and grease lubricants. Thus, it is necessary to develop new circuit solutions for pumping units of the crank type, to improve mobile refueling facilities with a modernized design of the pump unit drive of the mobile lubrication and filling station MRS.
