Description

A kind of piston pump
Technical field
The present invention relates to a kind of piston pumps.
Background technique
Piston pump is called electric reciprocating pump, is divided into single cylinder and multi-cylinder from structure, its main feature is that lift is higher.Suitable for conveying Oil emulsion etc. of the room temperature without solid particle.For oil field, coal-bed flooding, oiling, oil recovery;The kinetic pump of gun pressure machine hydraulic press, Hydro-blasting, chemical fertilizer factory convey ammoniacal liquor etc..If flow passage components are stainless steel, corrosive liquids can transport.According further to structure The difference of material can also convey high temperature tar, sludge, high concentration mortar, high viscosity liquid etc..
Three the cylinder pistons pump is to use three piston pump associated working, three pumps using a kind of relatively more extensive piston pump Three cylinder barrels row arranged side by side, three connecting rods are mutually 120 ° with being mounted on a crankshaft.Common three the cylinder pistons pump, structure are Membrane type extracts piston mode, its piston takes into account the effect of inlet valve, and when piston is twitched, the glue wrist of end plays valve block Effect.Because of reasons in structure, it can not accomplish very big pressure and flow, range of regulation is generally between 0~5Mp, for those streams Amount requires bigger equipment often unable to do what one wants very much to do.
Summary of the invention
The purpose of the present invention is overcoming the deficiencies of existing technologies and insufficient, it is small to provide a kind of big flow, the operation is stable, weight Piston pump.
In order to achieve the above object, the technical solution of the invention is as follows: a kind of piston pump, including pump case, the pump housing and pump head, The pump head includes the cylinder barrel of three rows arranged side by side, and crankshaft is equipped on the pump housing, and crankshaft gos deep into pump body, the crankshaft On be connected with three connecting rods, the other end of the connecting rod is connected with intermediate bar, and the end of the intermediate bar is equipped with piston, Three connecting rods are mutually 120 ° of angles, it is characterised in that: the piston includes ceramic jacket and sealing ring, and the sealing snare is being made pottery The outside of insulator, inlet valve and outlet valve are additionally provided in the pump head, and the making material of ceramic jacket is 99 porcelain, the sealing ring Making material be polytetrafluoroethylene (PTFE).
Compared with prior art, the invention has the benefit that
1, the structure membrane type that the piston in the present invention takes piston and inlet valve to separate, inlet valve and outlet valve are respectively whole The improvement of the inlet and outlet of a runner, this structure can make water pump obtain the bigger pressure of more stable output and greater flow, warp After crossing improvement, the pressure of this piston pump can achieve 24MPa or more, and guarantee flow 8m3 per hour, can use including general Outside the purposes of logical piston pump, moreover it is possible to be used in large-scale cleaning machine, sweeper, on fire fighting truck etc..
2, the present invention use 99 porcelain as piston friction medium, new material of 99 porcelain as high-end porcelain, with high temperature resistant, Corrosion-resistant, the wear-resisting, characteristics such as hardness is high, and ceramic surface can finish can reach 0.05, be substantially reduced in the reciprocal fortune of high speed Friction in dynamic reduces calorific value;Sealing element is made of polytetrafluoroethylene (PTFE), it is ensured that sealing element is in high-speed and high-temperature dynamic friction The case where system be still able to maintain prolonged dynamic sealing characteristic.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention.
In figure: the pump housing 1, pump head 2, cylinder barrel 3, crankshaft 4, connecting rod 5, intermediate bar 6, piston 7, ceramic jacket 8, sealing ring 9, into Water valve 10, outlet valve 11.
Specific embodiment
Below in conjunction with Detailed description of the invention and specific embodiment, the present invention is described in further detail.
Referring to Fig. 1, a kind of piston pump, including the pump housing 1 and pump head 2, the pump head 2 include the cylinder barrel 3 of three rows arranged side by side, Crankshaft 4 is installed, crankshaft 4 gos deep into inside the pump housing 1, and three connecting rods 5, the company are connected on the crankshaft 4 on the pump housing 1 The other end of extension bar 5 is connected with intermediate bar 6, and the end of the intermediate bar 6 is equipped with piston 7, and three connecting rods 5 are mutually 120 ° of folders Angle, the piston 7 include ceramic jacket 8 and sealing ring 9, and outside of 9 sets of the sealing ring in ceramic jacket 8 is also set in the pump head 2 It is equipped with inlet valve 10 and outlet valve 11, the making material of ceramic jacket 8 is 99 porcelain, and the making material of the sealing ring 9 is polytetrafluoro Ethylene.
The operation principle of the present invention is that: when piston pump work, engine is driven the crankshaft 4 of driving piston pump by belt, Crankshaft 4 is moved back and forth in pump head 2 by the transmission effect band piston 7 of connecting rod 5 and intermediate bar 6.When piston 7 to When right movement, 2 internal pressure of pump head is less than external pressure, and outlet valve 11 blocks, and inlet valve 10 is opened, and medical fluid passes through inlet valve 10 Into in pump head 2;When piston 7 moves downward, 2 internal pressure of pump head is greater than external pressure, and inlet valve 10 blocks, outlet valve 11 It opens, medical fluid is flowed out by outlet valve 11.Three pistons 7 in pump head 2 are at 120 ° of angles, it is ensured that are moving back and forth Chinese medicine The disengaging that industry can continue, the setting of three inlet/outlet valves can guarantee that the flow of piston pump reaches maximum.
