摘要:
A method for controlling a compressor that includes a compressor element, whereby during a transition from full load or partial load to zero load, a process A is followed that involves: (1) reducing the inlet pressure; and (2) reducing the speed and/or the drive torque. During a transition from zero load to part load or full load, a process B is followed that involves: (3) increasing of the speed or drive; and (4) increasing the inlet pressure.
摘要:
Method for recovering energy when compressing a gas using a compressor system with two or more compression stages, with each stage having a compressor element. Downstream from at least two compressor elements there is a heat exchanger having a primary and a secondary part. The coolant is guided successively in series through the secondary part of at least two heat exchangers, and the guiding sequence is chosen such that the temperature at the inlet of the primary part of at least one subsequent heat exchanger is higher than or equal to the temperature at the inlet of the primary part of a preceding heat exchanger, relative to the direction of flow of the coolant. At least one heat exchanger is provided with a tertiary part for a coolant.
摘要:
Improved low-pressure screw compressor provided with a rotor housing (2) with an inlet side and an outlet side, whereby in this rotor housing (2) are provided two rotor bodies (3 and 4) which each consist of a shaft (5, 7 respectively) and a screw (6, 8 respectively) which is provided round the above-mentioned shaft (5 or 7), whereby the rotor bodies (3 and 4) are bearing-mounted in said rotor housing (2) with their shafts (5 or 7), and whereby each of the rotor bodies (3 and 4) is bearing-mounted on the inlet side of the rotor housing (2) with a single loose bearing and on the outlet side of the rotor housing by means of a single fixed cylindrical roller bearing (15).
摘要:
Method for mounting a bush round a part (2) of a shaft with a force fit, which method comprises the following steps: - providing a guide element (7,23) with an outer surface (8) which is at least partly conical; - providing the guide element (7,23) in the extension of the aforesaid part (2) of the shaft (1);- pushing the bush (5) over the guide element (7,23) on the part (2) of the shaft (1).
摘要:
Method for the removal of organic components from a mixture of organic components and water, characterised in that it comprises the steps of guiding the mixture through at least one vessel (3) in which has been provided an amount of organoclay (17) in at least one removable casing (18) which is permeable to liquids and gasses but not to organoclay particles, or on a supporting structure (28) from where the organoclay particles cannot come off, such that the amount of organoclay particles is at any time part of a removable entity; and of producing a flow through the aforesaid mixture in this vessel (3).
摘要:
Minimum pressure valve having a housing (13) with an inlet (14) and an outlet (15) and in which has been provided a valve body (21) which is pushed against a seating (30) round the inlet (14) in a closed position, and whereby the valve body (21) is situated at a distance from the above-mentioned seating (30) in an open position, such that the inlet (14) is connected to the outlet (15), whereby the valve body (21) is provided in a sliding manner in a valve casing (17) confining, together with the valve body (21) an inner space (36) that is connected to the inlet (14) via a duct (35).
摘要:
Method for cool drying gas containing water vapour, whereby this gas is led through the secondary part of a heat exchanger (2), whose primary part is the evaporator (3) of a cooling circuit (4), whereby the temperature or the dew point is measured in the environment of the place where, when cool drying, the temperature of the gas to be dried is the lowest, and whereby the above-mentioned method comprises the step of switching off the cooling circuit (4) when the decrease of the lowest measured gas temperature (LAT) or the dew point during a predetermined period of time amounts to less than a preset value (y).
