hydraulic pump

Voorbeeldzinnen

1. in the case of other hydraulic steering gear, a driving engine and connected pump.
2. .3 in the case of other hydraulic steering gear, a driving engine and connected pump.
3. .1 a centralised hydraulic system with two independent power sources each consisting of a motor and pump capable of simultaneously closing all doors.
4. .2 an independent hydraulic system for each door with each power source consisting of a motor and pump capable of opening and closing the door.
5. Additional or independent power may be produced by any mechanical, hydraulic, pneumatic or electrical system, or by any combination of these (for example by an oil pump, air pump or battery, etc.).
6. in the case of electrohydraulic steering gear, an electric motor and its associated electrical equipment and connected pump; 3. in the case of other hydraulic steering gear, a driving engine and connected pump.
7. .7.3 Power-operated sliding watertight doors shall have either: .1 a centralised hydraulic system with two independent power sources each consisting of a motor and pump capable of simultaneously closing all doors.
8. ‘circulator’ means an impeller pump which has the rated hydraulic output power of between 1 W and 2500 W and is designed for use in heating systems or in secondary circuits of cooling distribution systems;
9. In addition, there shall be for the whole installation hydraulic accumulators of sufficient capacity to operate all the doors at least three times, i. e. closed-open-closed, against an adverse list of 15 °. This operating cycle shall be capable of being carried out when the accumulator is at the pump cut-in pressure. The fluid used shall be chosen considering the temperature liable to be encountered by the installation during its service. The power-operating system shall be designed to minimise the possibility of having a single failure in the hydraulic piping adversely affect the operation of more than one door. The hydraulic system shall be provided with a low-level alarm for hydraulic fluid reservoirs serving the power-operated system and a low gas pressure alarm or other effective means of monitoring loss of stored energy in hydraulic accumulators. These alarms are to be audible and visual and shall be situated on the central operating console at the navigating bridge; or
10. ‘circulator’ means an impeller pump which has the rated hydraulic output power of between 1 W and 2500 W and is designed for use in heating systems or in secondary circuits of cooling distribution systems; 2. ‘glandless circulator’ means a circulator with the shaft of the motor directly coupled to the impeller and the motor immersed in the pumped medium;
11. .2 an independent hydraulic system for each door with each power source consisting of a motor and pump capable of opening and closing the door. In addition, there shall be a hydraulic accumulator of sufficient capacity to operate the door at least three times, i. e. closed-open-closed, against an adverse list of 15 °. This operating cycle shall be capable of being carried out when the accumulators at the pump cut-in pressure. The fluid used shall be chosen considering the temperatures liable to be encountered by the installation during its service. A low gas pressure group alarm or other effective means of monitoring loss of stored energy in hydraulic accumulators shall be provided at the central operating console on the navigating bridge. Loss of stored energy indication at each local operating position shall also be provided; or
