A climate-control system may include first and second compressors and a suction manifold. The first compressor includes a first shell, a first compression mechanism, and a first suction inlet through which working fluid is drawn into the first compressor. The second compressor includes a second shell, a second compression mechanism, and a second suction inlet through which working fluid is drawn into the second compressor. The suction manifold includes first and second arms. The first arm provides working fluid to the first suction inlet. The second arm provides working fluid to the second suction inlet. The second arm includes a first suction pipe, a second suction pipe, and a suction valve. The suction valve is movable between a first position in which working fluid is allowed to flow through the first suction pipe and a second position in which working fluid is allowed to flow through the second suction pipe.

A method of lubricating a fluid production pump may include mixing a polarized lubricant with water to produce a diluted lubricant. The method may additionally include creating a flowpath within the fluid production pump. An initial volume of the diluted lubricant may be circulated within the flowpath to allow the diluted lubricant to react with components of the fluid production pump and form a protective barrier on the components of the fluid production pump. The method may further comprise repeatedly introducing a periodic volume of diluted lubricant into the fluid production pump according to a predefined lubrication schedule.

An orifice component for a lubrication system may include an orifice head having an outlet orifice and one or more inlet passageways in fluid communication with the outlet orifice. The orifice component may include an orifice stem extending from the orifice head. The orifice stem may have a solid structure.

A water resistance apparatus used for an oil cylinder, the oil cylinder including a press cover (10) and a piston rod (20) passing within press cover (10), and the water resistance apparatus including: a fluid inlet (14), which is arranged on the press cover (10); a fluid outlet (16), which is arranged on the press cover (10), the fluid outlet (16) and the fluid inlet (14) being in a staggered arrangement; a seal assembly (30), the seal assembly (30) being arranged between the press cover (10) and the piston rod (20); a fluid input assembly (40), the fluid input assembly (40) being connected with the fluid inlet (14); a fluid output assembly (70), the fluid output assembly (70) being connected with the fluid outlet (16). The fluid input assembly of the water resistance apparatus is able to perform cleaning on a pressure accommodating cavity as well as a hydraulic circuit and a valve connected with the pressure accommodating cavity, preventing the problem in current technology where an overflow element is unable to normally open or close due to a foreign substance within the pressure accommodating cavity clogging the overflow element of the fluid output assembly, and thus ensuring that sealed oil pressure is always established in the pressure accommodating cavity, allowing the seal assembly to normally operate, and consequently ensuring that a pumping operation can be carried out normally. Additionally, a pumping system which has the water resistance apparatus, a pumping machine, and a method of cleaning a pumping machine using the water resistance apparatus are disclosed.
