Abstract
The utility model relates to a high-temperature long-distance isolation diaphragm metering pump, which can convey high-temperature pressure fluid, avoids damage to the diaphragm and mechanical oil due to the fact that high temperature is transferred to the diaphragm and the mechanical oil, and comprises a casing, wherein an inner cavity of the casing forms an oil pool, and a plunger and a plunger cylinder body matched with each other are arranged in the casing. A diaphragm fixing support and a diaphragm front cover are connected onto the casing. A diaphragm and a pump cylinder body connected with an inlet end and an outlet end of a pump are arranged in the casing. The metering pump is characterized in that the diaphragm front cover is connected with the pump cylinder body through a pitot tube and an isolation liquid pipe sequentially. Process liquid or working media are cooled through cooling liquid, thereby effectively preventing the high temperature from being transferred to the positions of the diaphragm and the mechanical oil and having a protecting function. Due to the fact that the isolation liquid pipe is a rigid pipe, a channel can be ensured to be smooth, and flow resistance is small so as to be favorable for the cooling liquid to pass smoothly. In order to match with the installation of the isolation liquid pipe, the pitot tube is adopted for transition connection, and arrangement and adjustment of pipelines are facilitated.
Description
Technical field
The utility model relates to diaphragm metering pump structure field, the long-range isolation diaphragm metering pump of particularly a kind of high temperature.
Background technique
Diaphragm metering pump has become the main force's pump type in the fluid metering application at present.But the barrier film fixed support of conventional membrane metering pump, feed liquor valve and liquid valve all are fixed on the plunger cylinder; The temperature of pressure fluid passes to barrier film and machinery oil very soon; Receive the restriction of diaphragm material and machinery oil dielectric behavior, require the temperature of pressure fluid should not be too high.
Summary of the invention
The purpose of the utility model has provided a kind of realization and has carried the high temperature pressure fluid, avoids high temperature to be delivered to infringement barrier film and machinery oil and causes the long-range isolation diaphragm metering pump of high temperature of its damage.
For realizing that the technological scheme that above-mentioned purpose adopts is: the long-range isolation diaphragm metering pump of a kind of high temperature; Comprise that inner chamber constitutes oil sump and holds the plunger that cooperatively interacts and the housing of plunger cylinder; Be connected with barrier film fixed support and barrier film protecgulum on the housing; Barrier film is set in it, and the pump cylinder that is connected with pump inlet end and outlet end, it is characterized in that: the barrier film protecgulum links to each other with pump cylinder via Pitot tube, insulating liquid pipe successively.
Can be known by above technological scheme: the insulating liquid pipe is a double-layer composite pipe, and one of them pipeline supplies working medium to pass through, and another pipeline supplies cooling liquid to pass through; Through cooling liquid process liquid or title working medium are implemented cooling, can effectively avoid high temperature to be passed to barrier film and position, machinery oil place like this, thereby play a protective role; Because the insulating liquid pipe is a rigid pipe; Can guarantee the unimpeded of path like this, flow resistance helps passing through smoothly of cooling liquid for a short time, in order to cooperate the installation of insulating liquid pipe; Adopt the Pitot tube transition to connect with it ordinatedly, can make things convenient for the layout and the adjustment of pipeline like this.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is an insulating liquid pipe schematic representation in the utility model.
Embodiment
As shown in Figure 1; The long-range isolation diaphragm metering pump of high temperature; Comprise that inner chamber constitutes oil sump 11 and holds the plunger 12 that cooperatively interacts and the housing 10 of plunger cylinder 13, be connected with barrier film fixed support 14 and barrier film protecgulum 15 on the housing 10, barrier film is set in it; And the pump cylinder 50 that is connected with pump inlet end 51 and outlet end 52, barrier film protecgulum 15 links to each other with pump cylinder 50 via Pitot tube 30, insulating liquid pipe 20 successively.In fact above-mentioned insulating liquid pipe 20 is exactly the device of process liquid being implemented cooling, can adopt multiple structure, below specifies preferred concrete structure scheme.
Described Pitot tube 30 1 ends link to each other with barrier film protecgulum 15 via adpting flange 16, and the other end links to each other with insulating liquid pipe 20, and insulating liquid pipe 20 links to each other with cylinder body 50 via flange 40.Discretionary wiring method orchid 16, flange 40 realizations and being connected of cylinder body 50, barrier film protecgulum 15 are ten minutes better way modes in the concrete structure.Adopt Pitot tube 30 and barrier film protecgulum 15 and insulating liquid pipe 20 ways of connecting, can guarantee insulating liquid pipe 20 installation in position like this, Pitot tube 30 has adjustment adaptability, has made things convenient for the connection of pipeline.
In conjunction with Fig. 2; It is not only simply but also effective schemes that insulating liquid pipe 20 adopts the bimetallic tube body structures; Specifically be exactly pipe 21 and outer tube 22 in described insulating liquid pipe 20 comprises; Constitute airtight cavity between interior pipe 21 and the outer tube 22, the two ends of outer tube 22 are provided with cooling water intake 221, the coolant outlet 222 that is communicated with described airtight cavity, and described interior 21 two ends of managing link to each other with Pitot tube 30, cylinder body 50 respectively.
And between the flange 40 that insulating liquid pipe 20 is connected and the faying surface of cylinder body 50 mat insulation 41 is set, adopts mat insulation 41 can avoid flange 40 directly to contact and the transmission of heat phenomenon that occurs, at first stopped the approach of a part of heat transfer with the faying surface of cylinder body 50.
As the preferred structure of insulating liquid pipe 20, between the inwall at described outer tube 22 two ends and the interior pipe 21 retaining ring 23 is set, the three is welded as a whole.This structure can guarantee the basic fixed position of inner and outer pipe 21,22.
On the described insulating liquid pipe 20 liquid supplementation pipe 24 is set, the inner end of liquid supplementation pipe 24 is communicated with interior pipe 21, and the outer end extends to outer tube 22 outsides.
Described housing 10 is fixed on the base 60, and cylinder body 50 is fixed on supporting frame 70, and supporting frame 70 links to each other with base 60.
In the utility model, cooling water gets into, discharges from coolant outlet 222 from cooling water intake 221, and process liquid gets into and discharges from tap hole 17 from liquid supplementation pipe 24; Thereby realized the effect of process for cooling liquid; High temperature is implemented cooling by cooling water in insulating liquid pipe 20, especially insulating liquid pipe 20 directly is connected with cylinder body 50 via flange 40, and heat at first completely cut off a part of under the effect of mat insulation 41; The heat that is delivered to insulating liquid pipe 20 places is again by timely cooling; Effectively avoided the transmission of heat, and then protected barrier film and machinery oil, guaranteed the work that metering pump is safe and reliable to diaphragm pump one side.
