    The radial piston pump for pumping water, especially pure water, comprises a pump housing, a central drive mechanism and a surrounding pump mechanism which has a plurality of piston-and-cylinder units radially oriented and distributed about its circumference. Inlet and outlet valves for individual cylinder chambers are located in the vicinity of the piston-and-cylinder units. The drive mechanism is located in a housing chamber which has an oil sump. The housing chamber is surrounded by a cooling device comprising a plurality of gaps and ducts for conducting water to the inlet valves which are provided with a suction intake fitting for admitting water.

    专利说明:

    The invention relates to pumping equipment for radial-piston pumps of liquid injection with low-MVI lubricating properties, advantageous in water.
    The stump of the invention is the simplification of the cvciGMhi cooling design
     and with. is i shows a pump, a longitudinal section on f | 1 2 - section A-L in figure 1.
    Hydraulically piston pump for pressurized liquid with low lubricants. Preferably, you provide water for housing i with lid 2 installed to form a closed chamber 3 filled with lubricating fluid and limited by their walls to accommodate a drive eccentric mechanism including a drive shaft 4 with eccentrics 5 and a bearing 6 The piston groups 7 with inlet 8 and exhaust E valves iiacor are equipped with two oppoeltcho located at the ends of the pump with additional caps 10 and 11, established, c) an arranian gap between them and the location of the corresponding sections of the walls of the chamber 3 of the drive mechanism with the formation of two suction manifold and cooling system two bands 12 and 13, with both cavities 12 and 13 communicating among themselves through axial through channels 14 in the housing 1 and the main cover 2, while in the additional cover 10 the means for supplying the pumped medium in the form of a threaded hole 15, Axial channels 14 of the yen in the form of drilled holes
    In order to increase the efficiency of the cooling system, the walls of the housing 1 and the main cover 2 in the area of the cavities 12 m s3 of the bridge i of the suction collectors are equipped with ribs 16 and 17, respectively, protruding towards the additional covers 10 and 11 to fill the chamber 3 with lubricating fluid a hole 18 with a plug 19 is provided for fluids from the carrier. Piston groups 7 are installed in housing 1 to form workers 10.
    Ndsos works as follows.
    When the rotation of the drive shaft 4, as a result of the interaction of the piston groups
    7 with the bearing 6 of the eccentric 5, there is a periodic increase and decrease in the volume of the working chambers 20. When the volume of the working chamber 20 increases, the pumped liquid from the cavity 13 of the suction manifold through the inlet valve
    8fills the working chamber 20. When the volume of the working chamber 20 decreases, the pumped liquid is forced out of it through the discharge valve 9 into the discharge manifold and further to the consumer. Flow of pumped fluid entering into
    the cavity 12 through the hole 15, through the channels 14 enters the cavity 13, while there is an intense heat removal from the wall sections of the housing 1 and the main cover 2 located in the cavities 13 and 12, respectively, which helps to stabilize the temperature in the chamber 3 filled with lubricant
