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.

A lubricating oil supply apparatus may include a rotational portion that rotates together with a rotational shaft and a fixed portion that maintains a fixed location thereof and supplies oil through a space that circles with respect to a rotational center of the rotational portion, thereby supplying oil regardless of a rotational direction of the rotational shaft.

An integrated oil system manifold is provided, which includes a combination of a reverse rotation protection element, a first pump check valve, a second pump check valve, and a pressure relief valve integrated with a housing. Furthermore, a combination of a temperature control element, a filter, a heat exchanger, an integral main pump assembly, and an integral auxiliary pump assembly may also be included in the integrated manifold. An associated method is also provided.

An oil injection apparatus includes: a storage unit extruding lubricating oil through an ejection hole formed at a lower end thereof; a discharge unit communicating with the storage through the ejection hole and discharging the lubricating oil outside according to a pumping operation; a plurality of discharge pumps arranged at regular intervals in a circumferential direction of the discharge unit and having respective first ends disposed in the discharge unit; and a driving unit rotating in a direction to sequentially press the first ends of the discharge pumps, which are disposed in the discharge unit, thereby causing the discharge pumps to perform the pumping operation in turn.

An integrated oil system manifold is provided, which includes a reverse rotation protection element, a main pump check valve, an auxiliary pump check valve, and a pressure relief valve, wherein the reverse rotation protection element, the main pump check valve, the auxiliary pump check valve, and the pressure relief valve are integrated with a housing of the integrated oil system manifold. Furthermore, a temperature control element, a filter, a heat exchanger, an integral main pump assembly, and an integral auxiliary pump assembly may also be included in the integrated manifold. An associated method is also provided.

A method for supplying compressed gas via an assembly (1) having a plurality of liquid-injected elements (6, 8) for compressing gas, wherein the method includes providing a first liquid connection between a first liquid circuit related to a first of the plurality of liquid-injected elements (6) and the second liquid circuit related to a second of the plurality of liquid-injected elements (8).

A hydraulic system, for example a seal oil system, includes a hydraulic feeding pump having a motor, a hydraulic motor having a generator, a cooler and a storage tank for receiving hydraulic fluid. The hydraulic feeding pump is configured to draw hydraulic fluid from the reservoir and to direct the fluid to one or more consumers (for example mechanical seals). The hydraulic motor installed downstream of the consumer drives an electric generator. The generator can be coupled to a VFD which controls the speed of the hydraulic motor. The electric power, generated by the generator, is fed back into the power grid.

A lubricant pump (14) and a method thereof are disclosed. The lubricant pump (14) includes a pump base (32) and a reservoir housing (30). The pump base (32) and the reservoir housing (30) define a lubricant reservoir for storing lubricant. One or more pump elements (34) extend at least partially into the lubricant reservoir. Heaters (36) are disposed on the pump base (32) proximate the pump elements (34). The heaters (36) are configured to heat the local area surrounding the pump elements (34), to thereby reduce the viscosity of the lubricant at the pump elements (34). The heaters (36) are electrically connected to a thermal switch (38) to control activation and deactivation of the heaters (36). With the lubricant pump (14) and the method thereof, the thermal switch (38) can control the heater (36) based on air temperature rather than the temperature of the lubricant, so the viscosity of lubricant is well controlled.

A lubrication system may include a lubricant pump configured to dispense lubricant, a motor mechanically coupled to the lubricant pump, and a lubricant sensor configured to sense an amount of lubricant dispensed by the lubricant pump and transmit sensor data associated with a sensed amount of the dispensed lubricant. The lubrication system may include a controller coupled to the lubricant sensor and the motor, the controller including one or more processors configured to execute a set of program instructions stored in a memory, the set of program instructions configured to cause the one or more processors to: receive an operation signal associated with the well pump, wherein the operation signal is transmitted to the controller when the well pump is activated, cause the motor to operate upon receiving the operation signal, receive the sensor data; and cause a change in a rate of the motor based on the sensor data.
