Abstract
The utility model provides a large-power air-cooling screw rod air compressor. The large-power air-cooling screw rod air compressor comprises a base plate, wherein the base plate is provided with a chassis and also provided with a screw rod main engine and a driving motor which are located in the chassis; the chassis is internally provided with a fan set located above the driving motor, an air guide cover located above the fan set and a cooler located above the air guide cover; the cooler comprises an oil cooler and an air cooler; the oil cooler and the air cooler are arranged in a splitting manner; the oil cooler is composed of a plurality of branch oil coolers; the branch oil coolers are connected by an I-shaped aluminum plate; two adjacent branch oil coolers are inserted into the two sides of the I-shaped aluminum plate respectively; a web plate of the I-shaped aluminum plate is provided with through holes for communicating the adjacent branch oil coolers. According to the large-power air-cooling screw rod air compressor, a whole cooler and a cooler with an integrated structure in the prior art are changed into a splitting type; the branch oil coolers are integrated into the oil cooler by an I-shaped aluminum structure; the reliability of the cooler is improved on the basis of basically not changing the original design of a set and not increasing the cost.
Description
Technical field
The utility model relates to a kind of high-power air-cooled screw air compressor.
Background technique
Cooling air compressor and the comparison of water-cooling air compressor unit, the cooling system of unit periphery good ventilation, does not have special system requirements except requiring, and be suitable for the poor area of water quality, thereby cooling air compressor is subject to user's welcome very much yet.The cooler of cooling air compressor generally all adopts top-type, and cooler comprises and be designed to holistic oil cooler and forced air cooler, and its advantage is as follows: 1. hot blast is directly discharged by top, and windage is little; 2. cooler utilizes unit box body to support, and supports simply, and unit cost is low; 3. unit inner space is larger, is convenient to maintenance.This class cooling air compressor is for the unit of middle low power, functional; But for powerful cooling air compressor, can be because the cold and hot temperature difference causes distortion, and cooler is higher because of the effect fault of deadweight, and reliability is poor.In addition, between oil cooler, with the mutual UNICOM of pipe, also greatly reduced the reliability of cooler.
Summary of the invention
In order to overcome the above-mentioned deficiency of existing high-power air-cooled screw air compressor, the utility model provides the high-power air-cooled screw air compressor that a kind of reliability is higher.
The technical scheme in the invention for solving the technical problem is: a kind of high-power air-cooled screw air compressor, comprise chassis, described chassis is provided with cabinet, described chassis is provided with screw host and the drive motor that is positioned at described cabinet, and the output shaft of described drive motor is connected with the live axle of described screw host;
In described cabinet, be also provided be positioned at described drive motor top fan unit, be positioned at described fan unit top wind scooper, be positioned at the cooler of described wind scooper top, described cooler comprises oil cooler and forced air cooler;
Described oil cooler and forced air cooler split arrange, described oil cooler is comprised of several minutes oil coolers, between described minute oil cooler, by I shape aluminium sheet, connect, described I shape aluminium sheet comprises web and is positioned at the wing plate at web two, the both sides that two minutes adjacent oil coolers insert respectively I shape aluminium sheet, offer the through hole for adjacent minute oil cooler of UNICOM on the web of described I shape aluminium sheet.
Further, between described screw host and described chassis, be provided with buffer casting.
The beneficial effects of the utility model are: the utility model changes into split type by the cooler of the one cooler in original technology and integrated structure, and between minute oil cooler, adopt the oil cooler that is integrated into of I-shaped constructed of aluminium, substantially not changing the original design of unit and not increasing on the basis of cost, improved the reliability of cooler.The unit advantage that this has not only kept overhead type cooler construction, is also conducive to the care and maintenance of old unit.

Fig. 2 is the structural representation of oil cooler.
Fig. 3 is the structural representation of I shape aluminium sheet.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
With reference to Fig. 1, Fig. 2, Fig. 3, a kind of high-power air-cooled screw air compressor, comprise chassis 1, described chassis 1 is provided with cabinet 2, described chassis 1 is provided with screw host 3 and the drive motor 4 that is positioned at described cabinet 2, and the output shaft of described drive motor 4 is connected with the live axle of described screw host 3.In the present embodiment, between described screw host 3 and described chassis 1, be provided with buffer casting 5.
In described cabinet 2, be also provided be positioned at described drive motor 4 tops fan unit 6, be positioned at described fan unit 6 tops wind scooper 7, be positioned at the cooler 8 of described wind scooper 7 tops, described cooler 8 comprises oil cooler 9 and forced air cooler;
Described oil cooler 8 and forced air cooler split arrange, described oil cooler 8 is comprised of several minutes oil coolers 10, between described minute oil cooler 10, by I shape aluminium sheet, connect, described I shape aluminium sheet comprises web 11 and is positioned at the wing plate 12 at web two, thereby in web 11 both sides, forms slot.The both sides that two minutes adjacent oil coolers insert respectively I shape aluminium sheet, offer the through hole 13 for adjacent minute oil cooler of UNICOM on the web 11 of described I shape aluminium sheet, guarantee flowing of oil.
The utility model changes into split type by the cooler of the one cooler in original technology and integrated structure, and between minute oil cooler, adopt the oil cooler that is integrated into of I-shaped constructed of aluminium, substantially not changing the original design of unit and not increasing on the basis of cost, improved the reliability of cooler.The unit advantage that this has not only kept overhead type cooler construction, is also conducive to the care and maintenance of old unit.
