Abstract
The utility model relates to a flame-proof oil and gas recovery vacuum pump, comprising a motor which is connected with a pump bracket, a pump body and a pump bonnet through bolts. The rotation shaft of the motor is connected with a rotor on which five eccentric rotary vanes are arranged. A pressure regulator valve is connected at the inner wall of the air intake port of the pump, and a flame arrester is connected at the inner wall of the air vent of the pump. The flame-proof oil and gas recovery vacuum pump is characterized in that the air intake port and the air vent of the pump, a pipeline and an airflow passage are arranged inside the pump bonnet. The flame-proof oil and gas recovery vacuum pump has the advantages of small volume, 40%smaller than an oil and gas recovery vacuum pump of the same flow which is provided with a motor. The flame-proof oil and gas recovery vacuum pump is good in safety, and the pressure regulator valve arranged inside the air intake port of the pump and the flame arrester arranged inside the air vent of the pump effectively improve the explosion and fire prevention capabilities of the vacuum pump.
Description
Technical field
The utility model relates to a kind of flame-proof type oil gas recovery vacuum pump.
Background technique
Along with the popularity rate of large-and-medium size cities automobile improves constantly, the safety of gas station and environmental issue become even more important.In safety and environment hidden danger that the gas station exists, oil gas is a most outstanding problem, and hydrocarbon seepage and uncontrolled discharging will cause the possibility of fire, blast to the gas station.Therefore, the first-selection of these problems is taken precautions against and avoided to the assembling gas recovery system for oil also with regard to becoming the oil company.
Country does not also formulate complete standard and the standard of a cover to the oil gas recovery plant at present, and there are problems such as volume is excessive, Security has much room for improvement in the oil gas recovery vacuum pump as the vitals in the oil gas recovery plant.
The model utility content
The purpose of this utility model is to provide a kind of flame-proof type oil gas recovery vacuum pump, and is little to reach volume, improves security requirement.In order to achieve the above object, technical solution adopted in the utility model provides a kind of traditional rotary-vane vaccum pump from translator, comprise motor, pump support, the pump housing, pump cover, rotor, pressure regulator valve, flame trap, wherein motor is connected by bolt with pump support, the pump housing, pump cover, motor rotation axis connects rotor, is equipped with five eccentric blades on the rotor.When rotating under the driving of rotor at motor, change the generation Negative Pressure Difference by several cavity volume that are divided into by blade, and then reach air-breathing and circulation exhaust.
The intakeport inwall of pump connects a pressure regulator valve, and the relief opening inwall of pump connects a flame trap, it is characterized in that the intakeport of pump, relief opening, pipeline and air-flow path are built in pump cover, can dwindle the volume of pump so significantly.
Described pressure regulator valve comprises spool, seal ring, spring, valve support, valve seat, and wherein spool embeds the valve support by seal ring, and spring and valve support are built in valve seat, and spring one end connects spool, and the other end connects valve base inner wall.When running into the variation of exhaust obstruction or internal pressure, the pressure regulator valve spool pumps under the effect of spring, reaches the pressure release purpose, and then plays explosion-proof.
Described flame trap comprises the ripple tortuous stainless steel sheets of literary composition and two stainless steel sheets, and the tortuous stainless steel sheets of its medium wave literary composition places between two stainless steel sheets, and spool is built in cranse then.When breaking out of fire, the tortuous stainless steel sheets of ripple literary composition can change the route of refraction flame, the flame trap fire prevention thickness of setting can prevent that flame from breaking through flame trap, stops flame to see through vacuum pump and enters in the underground oil and gas recovery channel and oil tank of connection, and then play anti-fire action.
Advantage of the present utility model is: volume is little, and it is little by 40 percent that its volume ratio carries motor oil gas recovery vacuum pump with flow; Security is good, and the flame trap that pressure regulator valve that the intakeport of pump is built-in and relief opening are built-in has improved explosion-proof, the fire resistance property of vacuum pump effectively.

Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing and an embodiment.
As shown in Figure 1, be the pump generalized section, comprise motor, motor is connected by bolt with pump support, the pump housing, pump cover, and motor rotation axis connects rotor, is equipped with five eccentric blades on the rotor, the intakeport inwall of pump connects a pressure regulator valve, the relief opening inwall of pump connects a flame trap, it is characterized in that the intakeport of pump, relief opening, pipeline and air-flow path are built in pump cover.When rotor under driven by motor during high speed rotating, it slides along the inwall of the pump housing all the time, makes blade reciprocatingly slide and contact all the time with pump housing inwall along its radial groove, and cavity is divided into several variable volumes.Volume-variation by several cavitys forms atm difference, has just formed negative pressure (being called vacuum again) and produce gas flow when the pressure in the pump housing is less than standard atmospheric pressure, and then reached air-breathing and circulation exhaust.
As shown in Figure 2, for the pressure regulator valve generalized section, comprise spool, spool is inserted the valve support by seal ring, and spring and valve support are built in valve seat, and spring one end connects spool, and the other end connects valve base inner wall.When running into the variation of exhaust obstruction or internal pressure, when will increasing with back pressure, opens spool, and back pressure is big more, and the passway is opened big more and is reached to the pressure release purpose.If vacuum pump outlet is when unblocked, spool can be pulled down near seal ring and the closing passage mouth by the contractile force of spring, and whole process all is automatic adjusting
As shown in Figure 3, Figure 4, described flame trap comprises the tortuous stainless steel sheets of ripple literary composition, and the tortuous stainless steel sheets of ripple literary composition places between two stainless steel sheets, and spool is built in cranse then.When breaking out of fire, the tortuous stainless steel sheets of ripple literary composition can change the route of refraction flame, and the flame trap fire prevention thickness of setting can prevent that flame from breaking through flame trap, stops flame to see through vacuum pump and enters in the underground oil and gas recovery channel and oil tank of connection.
