The special equipment of gas stations are mainly oil tanks, oil pipelines and tankers. The function is to store, transport and refuel oil. Submersible pump depends on how you refuel. Generally, there are two ways: First, an oil pump can be installed inside the tanker and vacuum pumping can be used. The other is to install a submersible pump in the oil tank to supply oil at positive pressure. The latter effect is better. The gas station recovery system appeared in recent years, mainly for safety and environmental protection, reducing oil and gas emissions and polluting the environment, and improving the safety level accordingly. At present, many gas stations are equipped with oil tank level meters, which are connected with gas station computers, and management software is developed in the background, which can safely manage oil storage, realize remote data transmission and facilitate the management of superior companies.
