Technical field
The utility model relates to engineering machinery field, is specifically related to the air compressor of a kind of helical-lobe compressor and piston compressor series operation.
Background technique
Helical-lobe compressor has that volume is little, air displacement is large, the feature of smooth running, but pressure can not be too high, is generally no more than 13kg, and piston compressor has the strong feature of high pressure ability, but shortcoming to be volume comparatively large, cost is higher.The utility model is considered the advantages of above-mentioned two kinds of compressors got up and evade respective shortcoming, the air compressor that both series connection use junction has concurrently, the reliability of advantages is high.
Model utility content
The purpose of this utility model is: for Problems existing in above-mentioned background technology, a kind of screw rod-piston series connection air compressor is proposed, the utility model be utilize that helical-lobe compressor volume is little, air displacement is large, the feature of smooth running, plays the strong point that piston compressor high pressure ability is strong.Amount of leakage large, inefficient shortcoming when avoiding helical-lobe compressor high pressure, also reduces the volume of whole air compressor simultaneously, has floor space little, the advantage of reduced cost.
For realizing above-mentioned model utility object, the utility model have employed following technological scheme:
A kind of screw rod-piston series connection air compressor, comprise base, described base is installed with a helical-lobe compressor and a piston compressor, it is characterized in that, described helical-lobe compressor is connected with described piston compressor by deaerator, air-cooler, gas-liquid separator and filter successively, also comprise a motor for double-ended drive, described motor for double-ended drive drives described helical-lobe compressor and piston compressor by speed reducer simultaneously.Same motor drives two kinds of compressors, effectively reduces transmission loss.
Further, described piston compressor comprises one-level cylinder and secondary cylinder.
Further, described base is skid base.
Further, described helical-lobe compressor does not have outer cover and ventilation fan.
Further, described helical-lobe compressor and piston compressor carry out controlling run by same electric control box.
The compressor of two types is broken up and is redesigned into a unit by the utility model, by reasonably arranging that taking full advantage of limited space makes the floor space of a unit be 40% of the floor space of two units, greatly can save the work-yard of user, the gross weight of equipment also alleviates greatly.
Design principle:
For 20/40 type integrated machine: select air displacement when 1500 revs/min to be the helical lobe compressor host of 20M3/MIN, the air displacement of unit when can ensure to drive with 4 grades of motors.The piston compressor of W type (three row cylinders) is selected to make wherein two row cylinders compose in parallel the one-level cylinder of piston compressor, another row cylinder is used to become the secondary cylinder of piston compressor, by selecting suitable cylinder diameter and rotating speed, when making the exhaust pressure of helical-lobe compressor near 1MPa, the one-level exhaust pressure of piston compressor is 1.8 ~ 2.2MPa, and exhaust pressure is brought up to 4MPa by the second level cylinder of recycling piston compressor.Force rate at different levels is that a 250KW 4 grades of Double shaft-extension motor are selected in E2=1.9 ~ 2E3=1.9 ~ 2, E1=10 ~ 11, one end is connected with piston machine by speed reducer with the screw machine direct connection the other end, controls this motor and each Valve controlling point make this unit can reliably smooth running by an electric appliance control box.
Model utility advantage:
Screw rod described in the utility model-piston series connection air compressor utilizes that helical-lobe compressor volume is little, air displacement large, the feature of smooth running, plays the strong point that piston compressor high pressure ability is strong.Amount of leakage large, inefficient shortcoming when avoiding helical-lobe compressor high pressure, also reduces the volume of whole air compressor simultaneously, has floor space little, the advantage of reduced cost.
Accompanying drawing explanation

Embodiment 1:
As shown in Figure 1: a kind of screw rod-piston series connection air compressor, comprise base, described base is installed with a helical-lobe compressor and a piston compressor, described helical-lobe compressor is connected with described piston compressor by deaerator, air-cooler, gas-liquid separator and filter successively, also comprise a motor for double-ended drive, described motor for double-ended drive drives described helical-lobe compressor and piston compressor by speed reducer simultaneously.Same motor drives two kinds of compressors, effectively reduces transmission loss.
Described deaerator is also connected with oil cooler by pipeline, flow to helical-lobe compressor again through the cooled oil of oil cooler by back of pipeline.
Described filter comprises the coarse-grain filtering device and fine filter that are cascaded.
Further, described piston compressor comprises one-level cylinder and secondary cylinder.The pipeline that described one-level cylinder is connected with secondary cylinder is also connected with air-cooler and gas-liquid separator, and described secondary cylinder pressurized air is out transported to air taking port more again after air-cooler and gas-liquid separator.
Further, described base is skid base.Skid structure is adopted to make whole equipment be convenient to install, shift.
Further, described helical-lobe compressor does not have outer cover and ventilation fan.
Further, described helical-lobe compressor and piston compressor carry out controlling run by same electric control box.
The compressor of two types is broken up and is redesigned into a unit by the utility model, by reasonably arranging that taking full advantage of limited space makes the floor space of a unit be 40% of the floor space of two units, greatly can save the work-yard of user, the gross weight of equipment also alleviates greatly.
It is to be noted; as described above is only the preferred embodiment explaining the utility model; not attempt does any restriction in form to the utility model according to this; be with; all any modification or changes having relevant the utility model of doing under identical model utility spirit, all must be included in the category of the utility model intention protection.
