Description

Pressure oiling device for grouped vehicles

Technical Field

The utility model relates to an oiling device, especially a crowd's car pressure oiling device suitable for various engineering job sites and various construction vehicles belongs to refueling equipment technical field.

Background

As far as the applicant is aware, various in-use mechanical vehicle refueling operations are generally carried out at fixed or temporarily built refueling stations, and the number of vehicles that can complete refueling at one time is limited. In large-scale construction occasion, often need dispose a plurality of these kinds of filling stations and just can ensure the normal operation of engineering vehicle, often influence work efficiency because of the supply and demand is unbalanced in the practice, has delayed the construction progress, leads to the wasting of resources. Therefore, the market needs a refueling device which can meet the refueling operation of more vehicles.

Disclosure of Invention

The utility model aims to provide a: aiming at the problems in the prior art, the group vehicle pressure refueling device can simultaneously refuel a plurality of vehicles and ensure the safety and reliability of the operation process.

In order to achieve the purpose, the utility model discloses a crowd's car pressure filling device basic technical scheme is: the oil storage tank is communicated with an inlet of the pressure tank through a one-way valve after passing through the oil transportation pump assembly, the pressure tank is provided with an overflow valve overflowing and returning to the oil storage tank, an outlet of the pressure tank is communicated with a group of parallel oiling reels through an oiling pipeline after passing through a filtering separator, and the compressed air tank is connected with the oiling pipeline through a buffer after passing through a regulating valve.

When in oiling operation, the oil in the oil storage tank is pumped out by the oil transportation pump assembly and is conveyed to the pressure tank, and then the required number of vehicles are simultaneously oiled by the oiling reels respectively connected with the vehicle oil tanks through the filtering separator. In the process, when the oiling pressure is reduced and becomes small, the regulating valve is controlled to charge the buffer, so that the pressure of the oiling pipeline is kept constant; when a plurality of vehicles are refueled at the same time and the oil demand is large, the oil transportation pump assembly is kept to continuously transport oil to the pressure tank so as to maintain stable oil supply pressure and flow; when the pressure of the pressure tank exceeds a set value, the oil transfer pump assembly is controlled to stop, and the overflow valve overflows and releases pressure, so that the safety of the oiling process is ensured. Therefore, adopt the utility model discloses afterwards, not only can realize refueling simultaneously for a great deal of vehicle, moreover job stabilization is reliable.

Detailed Description

Examples

The technical solution of the present invention will be described in detail with reference to the accompanying drawings and specific embodiments, so as to further understand the objects, solutions and effects of the present invention, but not to limit the scope of the appended claims.

In the present embodiment, taking a group vehicle pressure refueling device in a road construction site as an example, as shown in fig. 1, fig. 2 and fig. 3, two oil storage tanks 2 transported by respective oil transport vehicles 1 respectively pass through valves 3 and then are communicated with inlets of pressure tanks 9 through oil transport pump assemblies on oil transport pump trailers 5 and then through check valves 7. The oil delivery pump assembly consists of a valve 5-3, a coarse filter 5-5, an engine pump 5-2 and a flow meter 5-4 which are arranged in series in an upper compartment body 5-6 of a trailer chassis 5-1. The pump inlet of the oil transportation pump assembly is provided with a vacuum gauge 4 for detecting inlet pressure, and the pump outlet is provided with a pressure gauge 6 for detecting outlet pressure.

The pressure tank 9 is equipped with an overflow valve 8 for overflow return to the tank and a tank pressure relay 10 for controlling the operating state of the oil pump trailer 5. The outlet of the pressure tank 9 is connected with an oil filling pipeline through a filtering separator 11, the oil filling pipeline is connected with a return loop oil circuit convenient for keeping pressure balance through an oil filling

pressure gauge

15, 100 oil filling reels 17 passing through respective flow meters 16 are connected on the return loop oil circuit in parallel, and an oil filling pressure relay 18 is arranged.

Meanwhile, the group vehicle pressure refueling device of the embodiment also comprises a compressed air tank 14 which is connected with the refueling pipeline through a buffer 12 after passing through a two-position three-way valve 13 controlled by a refueling pressure relay 18.

Controlling the oiling operation process: the vehicle was refueled by a 1 "flow meter 16 and refuel reel 17. When fewer vehicles are refueled, the refuelling pressure gauge 15 displays that the refuelling pressure is reduced slightly, and the refuelling pressure relay 18 controls the two-position three-way valve 13 to pressurize the buffer 12 so as to maintain the constant pressure of the refuelling pipeline; when more refueling vehicles are used, the pressure tank 9 is supplied with oil through the oil transfer pump trailer 5 to maintain stable oil supply pressure and flow; when the pressure of the tank body detected by the pressure tank pressure relay 10 exceeds a set value, the oil transfer pump trailer 5 is controlled to stop so as to ensure the pressure safety in the oiling process.

Experiments show that the group vehicle pressure refueling device of the embodiment solves the problem of insufficient refueling capability of the existing fixed refueling facility by a method of pressurizing and storing fuel and maintaining the pressure in a refueling pipeline to be stable by utilizing a buffer. The device has strong environmental adaptability, has the capability of filling fuel for 10-100 vehicles simultaneously, and has safe and reliable operation process and high working efficiency.

In addition to the above embodiments, other embodiments are also possible. All technical solutions formed by adopting equivalent substitutions or equivalent transformations fall within the protection scope of the present patent claims.
