Quais são os instrumentos completos (cinco metros) do grupo gerador a diesel?
Como todos sabemos, os grupos geradores a diesel geralmente são equipados com painéis de instrumentos , que são projetados para que os operadores observem e entendam as condições de trabalho de vários sistemas de grupos geradores a diesel. É geralmente estipulado na indústria que grupos geradores a diesel acima de 10KW devem ser equipados com instrumentos completos (comumente conhecidos como cinco medidores) e interruptores de ar.
1. Tacômetro
O tacômetro é utilizado para monitorar as rotações por minuto durante a operação do grupo gerador a diesel. Existem dois tipos de tacômetros: acionamento mecânico e acionamento elétrico. Para tacômetros acionados mecanicamente, a junta do eixo flexível é conectada diretamente ao eixo de acionamento na parte traseira do governador. O tacômetro elétrico consiste em um indicador de tacômetro e um sensor. O sensor é conectado ao tacômetro através de um fio.
2. Medidor de temperatura do óleo
O medidor de temperatura do óleo é usado para medir a temperatura do óleo no cárter do grupo gerador a diesel. Existem dois tipos de termômetro de óleo: tipo elétrico e tipo de resistência. Agora, o medidor elétrico de temperatura do óleo é amplamente utilizado, composto de sensor de temperatura, mostrador e fio do sensor.
3. Medidor de pressão de óleo
The oil pressure gauge is used to monitor the oil pressure in the main oil passage of the diesel generator. At present, the most widely installed oil pressure gauge on the instrument panel of diesel generator is the electrothermal oil pressure gauge, which is composed of sensor, information sensor wire and oil pressure gauge. The oil pressure sensor is installed on the cylinder block and connected to the main oil passage of the oil. The pressure gauge is installed on the instrument panel. The pressure gauge and sensor are connected through the information sensing wire. The oil temperature gauge is used to observe the oil temperature in the diesel generator oil pan. It has two types: thermoelectric type and resistance type. At present, thermoelectric oil thermometer is widely used, which is composed of temperature sensor, thermometer and sensing line.
4.Water temperature gauge
The water temperature gauge is used to measure the cooling water temperature of the diesel generator set cylinder head outlet pipe. Through this table, you can know the maximum and minimum temperature of the cooling water during the operation of the diesel generator set, so that the diesel generator set can operate at the optimal temperature. The water temperature gauge assembly is composed of sensor, sensing line and dial. The sensor is installed on the water outlet pipe of the cylinder head, the dial is installed on the outer plate, and the two are connected through the sensing wire.
5.Charging ammeter
The charging ammeter of the diesel generator set can display the charging and discharging current of the battery, and can also be used to judge whether the silicon rectifier generator and regulator have faults. The "+" pole terminal of the ammeter is generally connected to the "+" pole terminal of the charging generator or the armature terminal of the regulator, and the "-" pole terminal is usually connected to the battery terminal of the electromagnetic switch. The "+" pole terminal of the charging generator or the armature terminal of the regulator (diesel generator set started by the battery) is usually equipped with (- 20~+20) a ammeter on the external panel; For diesel generator set started by two batteries, an ammeter of (- 30~+30) A specification is usually installed on the external panel.
From the above contents, we know that the five necessary instruments for diesel generator set are: tachometer, oil temperature gauge, oil pressure gauge, water temperature gauge and charging ammeter. These dashboards can visually display various states of the device during operation. Therefore, the user must pay attention to its maintenance to ensure that all instrument panels can display normally when the equipment is working.
