21350 results about "Air compressor" patented technology

An air compressor is a device that converts power (using an electric motor, diesel or gasoline engine, etc.) into potential energy stored in pressurized air (i.e., compressed air). By one of several methods, an air compressor forces more and more air into a storage tank, increasing the pressure. When tank pressure reaches its engineered upper limit, the air compressor shuts off. The compressed air, then, is held in the tank until called into use. The energy contained in the compressed air can be used for a variety of applications, utilizing the kinetic energy of the air as it is released and the tank depressurizes. When tank pressure reaches its lower limit, the air compressor turns on again and re-pressurizes the tank. An air compressor must be differentiated from a pump because it works for any gas/air, while pumps work on a liquid.

Novel well cementation truck

The invention discloses a novel well cementation truck, which comprises a loading body, an electrical system, a plunger pump, a clear water manifold, a mud manifold and a high-pressure manifold, wherein the loading body is provided with a cross beam; the cross beam is provided with a hydraulic system, a power transmission system, a metering tank, an operating platform and a mixing system in sequence; the operating platform is provided with a gas path system and an operating system in sequence; the electrical system supplies power to the well cementation truck; the plunger pump, the clear watermanifold, the mud manifold and the high-pressure manifold are all arranged below the operating platform; the clear water manifold supplies water to the plunger pump and the mixing system; the mud manifold provides mud for the plunger pump; the plunger pump injects the mud into a well through the high-pressure manifold; and the well cementation truck also integrates with a steady pressure ash can,an air compressor and an air bottle. The novel well cementation truck has the beneficial effects that a spatial layout is optimized, and the steady pressure ash can, the air compressor and the air bottle are integrated in one well cementation truck. An ash feeding manifold is optimized, so that the steady pressure ash can supplies ashes, and ash supply equipment can be externally connected for supplying ashes. The large-volume air bottle is adopted, and therefore, air can be supplied to other equipment while the requirements of the well cementation truck are met.

The invention belongs to the field of petroleum equipment, and particularly relates to full-automatic intelligent remote controlled well solidifying equipment, and to a remote automatic cement supplying control system for well solidifying equipment. The remote automatic cement supplying control system comprises a control unit, an air compressor, a cement tank and a cement valve. The remote automatic cement supplying control system is characterized in that the control unit comprises an equipment end operating screen, an equipment end PLC processor, a remote control operating screen and a remotecontrol PLC processor; the equipment end operating screen, the equipment end PLC processor, the remote control operating screen and the remote control PLC processor are connected through netting twines; the equipment end PLC processor can remotely control a remote control module for starting and stopping the air compressor, thereby controlling the air compressor through the remote control module;after the air compressor is started, high-pressure air is discharged to the cement tank; the equipment end PLC processor automatically calculates a required cement supplying amount through a preset density of the well solidifying equipment; through comparing the calculated cement supplying amount with a current acquired cement supplying amount, proportion controlling and adjustment of the cementvalve are performed; and furthermore the cement supplying amount of the equipment is controlled.
