Abstract:
An integrated unit for use in a pump station. The integrated unit comprises a connector for connection to a power supply, a motor arranged to provide mechanical drive to an output shaft for coupling to a pumping unit associated with the pump station, a motor controller arranged to supply the motor with power from the connector to thereby control the motor, and an interface for a pump station system controller arranged to interface with the motor controller to match the mechanical drive supplied to the output shaft by the motor to demand. The integrated unit station comprises a housing with an exterior wall portion that is removable, and to which comprises a cooling system for an electronic component. An automatically engaging coupling is arranged to automatically disconnect the electrical connection to the electronic component on removal of the exterior wall portion.
Abstract:
A compressor may include a shell, a compression mechanism, first and second temperature sensors, and a control module. The shell may define a lubricant sump. The compression mechanism may be disposed within the shell and may be operable to compress a working fluid. The first temperature sensor may be at least partially disposed within the shell at a first position. The second temperature sensor may be at least partially disposed within the shell at a second position that is vertically higher than the first position. The control module may be in communication with the first and second temperature sensors and the pressure sensor and may determine whether a liquid level in the lubricant sump is below a predetermined level based on data received from the first and second temperature sensors.
Abstract:
A method comprising determining a temperature of an oil inside a compressor (1); determining a temperature at a moveable part (5) of the compressor (1); and deriving whether the compressor (1) operates in a safe mode or in an unsafe mode based on an analysis of the determined oil temperature and the determined temperature at the moveable part (5).
Abstract:
The invention relates to a method and equipment for controlling an operating temperature of an air compressor. A compressor element (1) is used for compressing a mixture of air and oil and supplying it to an oil separator (3). In the oil separator (3), the air and the oil are separated from one another. The oil is led to an oil circulating pipe (7) so as to be returned to the compressor element. When necessary, at least some of the oil flowing in the oil circulating pipe (7) is supplied to cooling. The amount of oil to be supplied to cooling is used for controlling the operating temperature of the compressor such that it is as low as possible, but nevertheless so high that no condensation point is reached. The amount of the oil to be supplied to cooling is controlled by a thermostatic valve (11) based on a change in dimension of a controlling element such that the dimension of the controlling element is changed by an external command as necessary.
Abstract:
The invention relates to a method for regulating a compressor of a pressure supplying system. The compressor is switched on and off dependent on a threshold temperature of one or more components of the pressure supplying system, said threshold temperature being ascertained using a temperature calculating method. The respective threshold temperature is ascertained by correlating the reciprocal temperature dependence that exists as a result of heat transfer between adjacent components.
