One or more techniques and/or systems are disclosed for mitigating fluid loss or leakage from a fluid pump with a rotating shaft driving a pumping mechanism. A one-piece, combined packing gland-bushing component can have an internal seal that allows for use of lubricants at higher pressures. Further, the combined packing gland-bushing component can be configured with a removal component that allows for easier removal of the packing gland-bushing component from a pump shaft, and shaft packing box.

Disclosed herein is an integrated pump system in which a motor is directly coupled to a pump, preferably using a modular connection. The integrated pump system may operate in a uni-directional or bi-directional mode. The integrated pump system incorporates an internal cooling channel which directs the returning low pressure hydraulic fluid past the controller and the motor for cooling purposes. The low pressure hydraulic fluid is also directly fed into the coupling between the motor and the pump to provide both cooling and lubrication.

A high-power turbine fracturing system may include a lubrication system, which may include a first lubrication unit configured to lubricate a plunger pump. The first lubrication unit may further include a high-pressure lubrication unit. The high-pressure lubrication unit may include a high-pressure motor, a high-pressure pump, and a high-pressure oil line. The high-pressure motor may be configured to drive the high-pressure pump, which may be configured to pump high-pressure lubricating oil into the high-pressure oil line. The high-pressure oil line may be configured to lubricate at least one of connecting rod bearing bushes or crosshead bearing bushes in the plunger pump.

A centrifugal separation type oil separator includes an oil separator body having a cylindrical body portion, and a bent pipe provided on an outer peripheral side of the body portion to surround the body portion in a circumferential direction, to introduce a fluid containing an oil into the oil separator body. The bent pipe includes an outer wall portion extending in the circumferential direction of the body portion and expanding radially outward from the body portion, and an inner wall portion extending along the outer wall portion and blocking an open part of the outer wall portion. The outer wall portion and the inner wall portion are formed by different members. An upper side of the body portion is open. The oil separator body has an upper cover blocking an open portion of the body portion. The inner wall portion and the upper cover are formed by an integral member.

The present invention relates to a gas supply pump comprising: a camshaft which can be rotated; a plurality of cam noses provided at regular intervals in a lengthwise direction of the camshaft and having an eccentric shape from the center of the camshaft; a cam roller provided to be in close contact with each cam nose; and a drive shaft and a piston provided to neighbor with one side of the cam roller; and a liquefied gas compression device which pressurizes and exhausts a liquefied gas according to a straight reciprocation of the piston.
