Described herein are processes that allow fluids that contain residual components such as oils, grease, and/or solids, and which are prone to the formation of scale, fouling, or corrosion, to be partially or fully evaporated. In some embodiments, the technology described herein relates to the development of an evaporator that contains a heat exchange surface that is plated with a corrosion and wear resistant metal. The evaporator assembly may also contain a mechanical scraper or wiper to continuously remove fouling, oil, grease, or other buildup that may otherwise inhibit heat exchange.

A method for supplying a sliding process material to or removing it from a surface of an object to be slid using a sliding part including a plurality of sliding bodies each having a flat working surface, the sliding part is regularly moved, preferably by a second driving mechanism, in parallel with the working surfaces of the sliding bodies and in a direction different from a moving direction of the sliding bodies while the sliding bodies are regularly moved, preferably by a first driving mechanism, in parallel with the working surfaces. This configuration uniformly supplies the sliding process material to the surface of the object to be slid.

An eccentric shaft assembly includes a first eccentric shaft including an interior surface forming a recess therein, an exterior surface, at least one first fluid inlet extending between the interior surface and the exterior surface, at least one first fluid outlet extending between the interior surface and the exterior surface. The eccentric shaft assembly further includes a second eccentric shaft disposed in the recess of the first eccentric shaft that includes a second bearing surface engaging the first bearing subassembly opposite the first bearing surface and at least one first fan blade for rotating about an axis of rotation to force a fluid to enter the recess through the first fluid inlet(s) and exit the recess through the first fluid outlet(s), to lubricate and/or cool a bearing subassembly disposed between the first eccentric shaft and the second eccentric shaft.

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.
