The main reasons for the discharge of oil in the tanker equipment are as follows:
1. The small float of the oil and gas separator of the oil tanker equipment cracks and enters the oil or falls off. The sealing performance of the outlet valve seat is not good, which leads to the failure of the outlet valve, a large amount of oil enters the atmospheric pressure chamber, and the conical valve (oil return valve) returns to If the oil is not enough, the oil can only be discharged from the exhaust pipe;
2. The large float is cracked and caused by too many impurities at the lower end of the parallel valve;
3. The cover gasket of the oil and gas separator is damaged. When refueling, the oil enters the normal pressure chamber from the high pressure chamber, which will cause the exhaust pipe to spit oil;
4. The pump cover or its gasket of the combined pump of the fuel dispenser is damaged, because the oil and gas separation pipe is not tightly sealed, so the oil condition of the exhaust pipe during fueling occurs;
5. There is another situation that the oil dispenser equipment is turned on for many times without refueling but spitting oil, but the phenomenon of spitting oil will disappear when refueling.
The above is the introduction of the reasons why the exhaust pipe spitting oil occurs in the use of the tanker equipment. Customers and friends should check and eliminate the reasons and solve them accordingly.
