Description

A kind of increasing enthalpy inlet duct and multicylinder compressor

Technical field

The utility model relates to air compressor field more particularly to a kind of upper and lower cylinder increasing enthalpy tonifying Qi are non-interference, upper, Lower cylinder will not gas blowby increasing enthalpy inlet duct and multi-cylinder enthalpy-increasing compressor.

Background technique

With the development of science and technology and society, compressor is widely used.Especially refrigeration industry, compressor are One of core equipment.The multicylinder compressor of the prior art, for example, as shown in Figure 1, common duplex cylinder compressor comprising: upper, Lower cylinder body, the partition 03 between two cylinder block, set on the external side of upper cylinder upper flange lid and be set to lower cylinder it is external The lower flange lid of side.Upper crankshaft can be connect with rotor, and upper crankshaft and lower crankshaft are integrated manufacture, and by upper cylinder body Enter lower cylinder body across partition.As shown in Figure 2 and Figure 3, the air entry 1,2 of the upper and lower cylinder block of existing duplex cylinder compressor is all same One angle, therefore increasing enthalpy tonifying Qi (or hydrojet) air inlet 04 is also set to the same position of partition 03, and then point upper and lower jet port 05. It is symmetrical arranged because the crankshaft (i.e. cam) in upper and lower cylinder has been staggered 180 °, " a cylinder air-breathing, a cylinder row when compressor operating Gas ", a therefore when cylinder is low-pressure state another cylinder is high pressure conditions, is influenced by seal distance and jet port size, when needing When wanting increasing enthalpy tonifying Qi, upper and lower cylinder is easy for forming gas blowby.

Therefore, how to overcome the upper and lower cylinder of existing multicylinder compressor to be easy the defect of gas blowby is industry urgent problem to be solved.

Utility model content

The utility model in order to solve the upper and lower cylinder of existing multicylinder compressor be easy gas blowby the technical issues of, propose this Kind upper and lower cylinder increasing enthalpy tonifying Qi is non-interference, upper and lower cylinder will not gas blowby increasing enthalpy inlet duct and multicylinder compressor.

The utility model proposes a kind of increasing enthalpy inlet duct comprising: partition is separated by one in the septum plane Two increasing enthalpy air inlets of angle.Wherein, the jet port of an increasing enthalpy air inlet is towards a surface of the partition, another increasing enthalpy air inlet Jet port towards another surface of the partition.

Preferably, the two increasing enthalpy air inlets can be separated by 180 ° and be arranged radially.

The utility model also proposed a kind of multicylinder compressor comprising: the upper and lower cylinder with air entry, it is described it is upper, Increasing enthalpy inlet duct provided by the utility model is equipped between lower cylinder, the injection of an increasing enthalpy air inlet in the increasing enthalpy inlet duct Mouth is connected to the upper cylinder, and the jet port of another increasing enthalpy air inlet and the lower cylinder connect in the increasing enthalpy inlet duct It is logical.

Preferably, the air entry of the upper cylinder is connected to the first dispenser, the air entry of the lower cylinder and second point The connection of liquid device.

Preferably, the angle between the air entry of the upper and lower cylinder is 180 °.

The increasing enthalpy air inlet angle of upper and lower two cylinder is staggered by the utility model, so that the jet port of two increasing enthalpy air inlets does not have Have and directly communicate, so that upper and lower cylinder increasing enthalpy tonifying Qi (or hydrojet) is non-interference, to solve asking for upper and lower cylinder blow by Topic.It is optimal to be staggered 180 ° if two cylinder air entry angles are accordingly staggered an angle, in this way in cylinder radially relative equilibrium, The vibration of compressor can be reduced, increasing enthalpy (or hydrojet) air inlet is also accordingly staggered 180 °, can be effectively prevented upper and lower cylinder The generation of gas blowby.The size selectivity of increasing enthalpy air inlet is bigger simultaneously.

Specific embodiment

The utility model is further described below with reference to embodiment and attached drawing.

As shown in Figure 4, Figure 5, the utility model proposes increasing enthalpy inlet duct preferred embodiment, the device include: every Plate 3, the two increasing enthalpy air inlets for being separated by an angle in 3 plane of partition.Wherein, 5 court of jet port of an increasing enthalpy air inlet 4 The upper surface of the partition, the jet port 7 of another increasing enthalpy air inlet 6 is towards the lower surface of the partition.In the present embodiment, two increase Enthalpy air inlet is arranged radially and can be separated by 180 °.As needed, two increasing enthalpy air inlets can choose different angles, as long as making The jet port for obtaining two increasing enthalpy air inlets is not communicated with, and upper and lower cylinder increasing enthalpy tonifying Qi is non-interference, so that it may overcome cylinder gas blowby up and down Defect.

Such as Fig. 6, Fig. 7, the utility model also proposed a kind of preferred embodiment of multicylinder compressor, in the present embodiment, be Duplex cylinder compressor comprising: the upper cylinder with air entry 1 and the lower cylinder with air entry 2 are equipped between upper and lower cylinder The increasing enthalpy inlet duct 3, the jet port 5 of the increasing enthalpy air inlet 4 on right side is connected to upper cylinder in the increasing enthalpy inlet duct, this The jet port 7 of the increasing enthalpy air inlet 6 in left side is connected to lower cylinder and (please refers to Fig. 4, Fig. 5) in increasing enthalpy inlet duct.Upper cylinder Air entry 1 is connected to the first dispenser 8, and the air entry 2 of lower cylinder is connected to the second dispenser 9.Since this duplex cylinder compressor has There are two air entry and two increasing enthalpy air inlets, therefore need to increase the dispenser each one of the dispenser of air entry, increasing enthalpy air inlet It is a.The pressure of inspiration(Pi) pulsation inside dispenser on the one hand can be reduced in this way, reduce compressor noise；On the other hand it also corresponds to add Big dispenser volume, increases air inflow, improves compressor efficiency.Folder between the optimal air entry for setting upper and lower cylinder Angle is 180 °, and so diametrically opposed balance of compressor can reduce vibration of compressor.4 phase of increasing enthalpy air inlet of upper cylinder It is 90 ° ~ 100 ° to the angle that the air entry 1 of the upper cylinder of its tonifying Qi is unfolded counterclockwise, the increasing enthalpy air inlet 7 of lower cylinder is opposite The angle that the air entry 2 of the lower cylinder of its tonifying Qi is unfolded counterclockwise is also 90 ° ~ 100 °, i.e. between two increasing enthalpy air inlets 4,6 Angle is also 180 °.Since two air entries have been staggered 180 °, and to have been separated from tonifying Qi non-interference for two cylinders, then will not gas blowby.

As needed, as long as two increasing enthalpy air inlets are staggered, certain angle is arranged, as long as and the air entry of two cylinders can expire Foot installation and structural strength, some angles that is staggered can prevent cylinder gas blowby up and down.As shown in figure 8, the air entry of two cylinders is staggered A little it is arranged, then two increasing enthalpy air inlets 4,6 can be staggered certain angle, so that it may prevent gas blowby up and down.

Embodiment described above is primarily to illustrate the creating conception of the utility model, it is noted that for this For the those of ordinary skill in field, without departing from the concept of the premise utility, several deformations can also be made and changed Into these are all within the protection scope of the present invention.
