\t\t\t\t\t\tThe cooling system of the car<\/span> charger should pay attention to the condition of the refrigerating oil during the operation. After the compressor is started, carefully observe the changes in the oil temperature and oil pressure. If the oil changes color, the oil must be changed until the system is clean. Piston refrigerators that are normally put into production and operation must undergo a limited period of maintenance after long-term operation and replace the refrigerating oil.<\/p>\n

1. Procedimentos operacionais de substitui\u00e7\u00e3o do \u00f3leo de refrigera\u00e7\u00e3o<\/span><\/p>\n

1. Fechar as v\u00e1lvulas de fecho de alta press\u00e3o de escape e de baixa press\u00e3o de aspira\u00e7\u00e3o e utilizar a agulha da v\u00e1lvula de processo no compressor para libertar o refrigerante no interior do compressor, de modo a que o c\u00e1rter do compressor comunique com a atmosfera.<\/span>
2. Desaperte o buj\u00e3o de drenagem de \u00f3leo no fundo do c\u00e1rter, drene o \u00f3leo refrigerante no c\u00e1rter e retire o filtro para limpeza.<\/span>
3. Nitrogen can be blown in from the low-pressure inflation valve needle, and the oil drain port can be blocked by hand to increase the pressure in the body, and further remove the residual oil in the body, dry the cleaned filter into the body and tighten the oil drain plug .<\/span><\/p>\n

2. Refrigerating oil injection<\/span><\/p>\n

Op\u00e7\u00e3o 1: Desaparafusar o \u00eambolo da porta de processo no lado do c\u00e1rter do compressor, utiliz\u00e1-lo como porta de enchimento para verter o \u00f3leo refrigerado no c\u00e1rter atrav\u00e9s de uma ferramenta adequada;<\/span>
Op\u00e7\u00e3o 2: (para a m\u00e1quina de pist\u00e3o) ligar o tubo de baixa press\u00e3o do medidor de enchimento de fl\u00faor \u00e0 agulha da v\u00e1lvula de processo de baixa press\u00e3o da cavidade do frigor\u00edfico de tipo pist\u00e3o, utilizar uma bomba de v\u00e1cuo para bombear o c\u00e1rter para press\u00e3o negativa e remover o outro tubo de enchimento de fl\u00faor separadamente, uma extremidade Inseri-lo no recipiente que cont\u00e9m o \u00f3leo refrigerado e ligar a outra extremidade \u00e0 agulha da v\u00e1lvula da extremidade de suc\u00e7\u00e3o de baixa press\u00e3o da bomba de \u00f3leo e aspirar o \u00f3leo refrigerado para o c\u00e1rter utilizando a press\u00e3o negativa no c\u00e1rter.<\/span><\/p>\n

Summary of considerations:<\/span>
<\/span>
1. You can add a little less when changing the oil, and generally add it to the lower limit of the sight glass.<\/span>
2. Ap\u00f3s o enchimento do \u00f3leo de refrigera\u00e7\u00e3o, aperte o \u00eambolo do processo ou retire o tubo de enchimento de fl\u00faor e ligue o man\u00f3metro de fl\u00faor para aspirar o compressor.<\/span>
3. After the vacuum is completed, open the compressor high and low pressure stop valve to check whether there is refrigerant leakage.<\/span>
4. After turning on the cooling system, check the compressor lubrication and the oil level of the oil glass immediately. If the oil level is lower than the normal range, add refrigerating oil. If necessary, connect an oil pressure gauge to the needle valve of the oil pump to check the oil pressure.<\/span>
5. A press\u00e3o do lado de suc\u00e7\u00e3o da bomba de \u00f3leo do compressor de pist\u00e3o semi-herm\u00e9tico deve ser basicamente a mesma que a press\u00e3o de suc\u00e7\u00e3o de baixa press\u00e3o, e o valor admiss\u00edvel da diferen\u00e7a de press\u00e3o do \u00f3leo.<\/span><\/p>\n

Matters needing attention:<\/span>
The refrigerated oil in the cooling system of the car<\/span> charger is hygroscopic, and the moisture in the oil chemically reacts with the oil. It requires special care when working to minimize the air entering the system and the oil storage container; the refrigerating oil should not be added in excess. If the refrigerating oil is added in excess, There is a danger of liquid shock when the cooling system is reopened.<\/span><\/p>","protected":false},"excerpt":{"rendered":"
