Many drivers’ friends seldom follow the safe operation procedure of the fuel tanker while using the refueling vehicle. They rely on their own experience to drive or refuel the user. Here, Hubei Dali Special Purpose Vehicle Manufacturing Co., Ltd. has special tips, with fuel dispensers. When the oil tanker measures fuel outwards, the idle speed should not be too large, so as to avoid excessive pressure damage to the oil pump and the tanker.
Recently, the production of mobile refueling vehicles by Hubei Dali Special Purpose Vehicle Manufacturing Co., Ltd. has become increasingly popular. Many users are the first time to contact the fuel tanker special equipment such as the computer tax-controlled mobile fuel dispensers. Therefore, some considerations in the use of fuel dispensers are not very important. To understanding:
1. When powering the fuel dispenser, ensure that the voltage is within the range of DC10V~DC30V so as not to damage the computer components by the peak voltage.
2. Because the fuel supply pump to the refueling machine is self-provided by the automobile, in order to ensure the pressure stability, the automobile pipeline should be equipped with an overflow valve. If not, it should be noted when ordering, requiring the refueling machine with a relief valve to avoid damage. Tanker.
3. When using the oil gun (oil dispenser automatically returns the reel), avoid using the oil gun's oil filling pipe to knock on the oil receiving container, press the switch and other incorrect operation, this operation may damage the root of the oil filling pipe and cause oil leakage. To check regularly, tighten the stop screw on the fill tube to prevent loosening or damage to the root of the fill tube.
4. The tank should be cleaned regularly to keep the oil clean.
5, tanker measurement verification according to JJG443-2006 "fuel refueling machine measurement verification procedures," the relevant provisions.
6. The filter is installed in front of the oil inlet of the tanker. Since the conditions of the oils are not the same everywhere, the replacement cycle of the filter cannot be clearly defined; when the flow of the tanker suddenly decreases, replace the filter; The traffic is still abnormal. Check whether other components affect the traffic. If the traffic is affected, replace the traffic.
7. When two tax-controlled refuelling trucks share the same pipeline to supply oil, a one-way valve must be installed on each branch pipe;
8. It is forbidden to use non-oil resistant rubber pad at the flange of the oil pipe of the tax-controlled fuel dispenser.
9. When connecting with the petrol station management system, the single power line and network cable are strictly prohibited from the same pipe;
10. Before installation of the new tax-controlled fuel dispenser, clean the mud sand, welding slag, and other debris inside the clean oil tank. Pressurized test confirms that it will not leak oil. Install a tax-controlled fuel dispenser to prevent debris from entering the fuel dispenser and damage it. part.
11. It is forbidden to pull out and insert the connection between the plates.
12. Always check the resistance between the fuel dispenser nozzle and the grounding terminal. The value should be less than 10Ω. Otherwise, replace the hose to ensure the smooth discharge of the electrostatic discharge circuit, thus ensuring the safety of the fuel station.
Although the refueling machine is divided into many brands, the method of use is basically the same, and the details of some users can be solved according to the actual situation. The refueling vehicles that Hubei vigorously produces can be equipped with a variety of refueling machine brands. Users can choose the various brands of refueling machines according to their preferences and requirements, such as Zhengxing, Jialijia computer tax control refueling machines and so on.
When you need to consult or repair, please contact our factory after-sales service department, and safekeeping of the purchase certificate to confirm the car is in the warranty period. Chassis car after-sales service by the chassis manufacturer responsible for the car; the factory only for the special modification of the vehicle part of the "three guarantees" in the use of the process, whenever and where there is a fault or problem, please call, email us, we Will be given promptly to handle and give a clear reply within 24 hours after receiving the information. Tanker trucks are divided into tankers and refuellers. As the name suggests, refuellers are used to add gasoline/diesel to other vehicles. This requires the installation of a tanker on the car. The refueler has large flow and small flow rates. Can choose according to your own fueling speed. For the use of fuel dispensers, it is not very clear to the users who bought the refueling vehicles for the first time. Then Hubei Dali Special Purpose Vehicle Manufacturing Co., Ltd. provides everyone with the use of refueling vehicles and precautions:
First, use the tanker
1. The oil and gas separator (combination pump) is equipped with a filter. The steel net should be washed with gasoline frequently (broken up should be replaced) and the dirt in the low pressure chamber should be removed to protect the pump and the flowmeter. The filter is located in the combination pump. Remove the end cap and remove it.
2. The underground oil tanks should be cleaned periodically to keep the tanks clean.
3. The oil pump is a vane pump. The pressure in the pump can be adjusted through the adjustment screw of the overflow valve to control the oil discharge of the tax-controlled fuel dispenser. This screw is adjusted at the factory to ensure that the amount of oil discharged meets the design requirements. After long-term use, if the oil discharge volume has decreased, the adjustment screw can be tightened inward to increase the pressure of the pump so that the oil discharge capacity can meet the requirements.
Note: The coupling surface between the vane pump body and the pump cover is sealed by the sealing ring, and it must be installed during inspection and reassembly.
4. The measurement accuracy adjustment of the whole machine (that is, the adjustment of the flow coefficient) shall be conducted in accordance with the relevant regulations of JJG443-98.
5, maintenance must be disconnected before power, no charge repair. Do not damage the flameproof surface when opening the explosion-proof terminal box. The foreign matter in the explosion-proof cavity during reassembly should be cleaned and the cable tightness should be good. Metal pads and gaskets must not be lost. The screws must be tightened reliably and in complete quantities to ensure the explosion-proof performance of electrical components.
6. Products that have passed the inspection of explosion-proof are not allowed to replace or modify the components and structures that affect the explosion-proof performance.
