摘要： A compressor assembly having a high velocity muffler system which produces a particle-free compressor pump feed while reducing noise output from the compressor assembly during compressing operations. The high velocity muffler system is maintenance-free and comprises an inertia filter. The compressor assembly uses a method for producing a compressor pump feed and reducing noise during compressing operations by processing a gas through the high velocity muffler system which has an inertia filter and a muffler chamber to produce a compressor pump feed which can be compressed by a pump assembly.

摘要： Cooling medium circulation systems for supplying a cooling medium through a single header to multiplexed heat exchangers are described. In an aspect, a system includes, but is not limited to, a storage tank configured to hold a cooling medium in a fluid state; first and second circulation pumps fluidically coupled to the storage tank; a single cooling medium header fluidically coupled with each of the circulation pumps; a first dryer module configured to direct a first portion of cooling medium from the single cooling medium header past a first stream of compressed air and to direct the first portion of cooling medium back to the storage tank; and a second dryer module fluidically configured to direct a second portion of cooling medium from the single cooling medium header past a second stream of compressed air.

摘要： A high pressure gas lift compressor system and method of using the system for supplying compressed gas to multiple wells are provided. The system includes a compressor having multiple compressor cylinders. Each cylinder has its own gas inlet line and dedicated gas outlet line that supplies compressed gas from that cylinder directly to a wellbore to provide artificial gas lift. Each cylinder also has its own control valve upstream of the cylinder to control the suction pressure to the cylinder. A desired gas flow rate to each well may be input, and the control valve is adjusted accordingly to achieve the flow rate. By inputting a flow rate for each separate cylinder, the flow rate to each well may be independently controlled.

摘要： A linear compressor includes a compressor body configured to compress a refrigerant. The compressor body includes a cylinder, a discharge valve, a groove, a gas hole, and a flow restrictor. The cylinder receives a piston. The discharge valve is configured to open and close one side of the cylinder and define a compression space for the refrigerant together with the piston. The groove is defined in an outer circumferential surface of the cylinder and into which at least a portion of the refrigerant discharged through the discharge valve is introduced. The gas hole is defined in the groove to pass through the cylinder. The flow restrictor includes twisting wires made of different materials and is disposed to be wound around the groove.

摘要： The present invention relates to a condensate drain valve, which is connected to a condensate discharge pipe of an air compression equipment, for discharging the condensate generated inside the air compression equipment together with compressed air to the outside, which comprises: a main body; an opening and closing member, and a communication path formed therein for communicating the inlet hole and the discharge hole. According to the present invention, the automatic drain valve for condensed water capable of continuously and automatically discharging the condensed water generated in the air compression device even during the operation of the air compression device can be formed in a compact structure, thereby facilitating the manufacture of the device and remarkably reducing the manufacturing costs.

摘要： An air compressor improves the dustproof performance of an intake path to a crankcase. The air compressor includes a compression assembly that reciprocates a piston in a cylinder to produce compressed air, a crankcase accommodating the compression assembly and having an inner inlet to allow outside air to be drawn, a filter located in the crankcase and covering the inner inlet from outside, a filter cover having an outer inlet and covering the filter from outside, and a dust cover covering the filter cover from outside, covering the outer inlet, and including an outer circumferential portion. The outer circumference portion and the filter cover have a space to draw outside air between the outer circumference portion and the filter cover.

摘要： A dryer is provided with a pressure vessel with a drying zone and regeneration zone. The regeneration zone comprises a first subzone and a second subzone. The dryer comprises a rotatable drum in the pressure vessel with a drying agent, and the outlet of the regeneration zone is connected to the drying zone via a connecting pipe with a cooler and condensate separator. A tap-off pipe is connected to the outlet of the drying zone and is also connected to the inlet of the second subzone. A blower is provided to realize a regeneration flow from the drying zone to the second subzone.
