Abstract
The utility model relates to a compressor, in particular to a reciprocating compressor comprising a starting device with pressure. The reciprocating compressor is capable of being started with pressure under the condition without pressure relief or a loop. The technical scheme includes that the reciprocating compressor is characterized by further comprising the starting device with pressure, the starting device with pressure comprises an instrument air valve, an instrument air storage tank, an electromagnetic valve and jacking air inlet valve mechanisms, air inlet valves on a front and rear cavities of each cylinder are provided with the corresponding jacking air inlet valve mechanisms, and the jacking air inlet valve mechanisms on the air inlet valves on the front and rear cavities of the cylinders can work synchronously to control the air inlet valves on the front and rear cavities of the cylinders to be opened or closed simultaneously. Owing to the scheme, shortcomings in the prior art are overcome, and piston force of the reciprocating compressor comprising the starting device with pressure is minimized.
Description
Technical field
This is practical newly to relate to a kind of compressor, is meant that especially need not can be with the reciprocal compressor of pressing starting under release and the loop-free situation.
Background technique
Existing reciprocal compressor structure and principle are basic identical; But their ubiquitous problems are can not be with to press starting; Need be the pressed gas pressure release in the cylinder, compressor start starting is all wanted after the release and has under the situation in loop to start, and can cause waste like this.
Summary of the invention
This practical new purpose is to overcome the deficiency that existing technology exists; Provide a kind of compressor suction valve to be backed down at prestart; Thereby the forward and backward cylinder of double-acting cylinder is communicated, and the pressure of the forward and backward cylinder of compressor double-acting cylinder is identical like this, makes the piston force of compressor drop to minimum; Starting compressor makes compressor accomplish to press with the novel band band of the zero load basically starting of pressure the reciprocal compressor of starting arrangement then.
In order to realize above purpose; The following technological scheme of this practical new employing: a kind of reciprocal compressor of pressing starting arrangement with band; Include motor, interstage cooler and cylinder; Be respectively arranged with suction valve on the front/back cavity of said every group of cylinder, it is characterized in that: also include band and press starting arrangement, this band presses starting arrangement to include instrument air valve, instrument wind gas holder, solenoid valve and back down suction valve mechanism; Wherein be provided with on the suction valve on every group of cylinder front/back cavity and back down suction valve mechanism, but and the suction valve mechanism synchronous working control cylinder front/back cavity upper inlet valve that backs down on the cylinder front/back cavity upper inlet valve open or close simultaneously.
Adopt such scheme, on the suction valve of each cylinder of reciprocal compressor, all be equipped with and back down suction valve mechanism, the power that backs down suction valve mechanism is instrument wind; Backing down the instrument wind of suction valve mechanism is controlled by one or more solenoid valves; Compressor backs down the work of suction valve mechanism on the suction valve of each cylinder of prestart, suction valve is backed down, thereby the forward and backward cylinder of double-acting cylinder is communicated; The pressure of the forward and backward cylinder of compressor double-acting cylinder is identical like this; Make the piston force of compressor drop to minimum, starting compressor makes compressor accomplish the zero load basically starting of band pressure then; Be that compressor can be with the pressure starting compressor under the situation of any pressure in the declared working condition scope, very efficient and energy-conservation.
Further being provided with again of the utility model is: said band presses the solenoid valve in the starting arrangement to be provided with two groups; They independently control respectively on two groups of cylinders of compressor back down suction valve mechanism or said band presses the solenoid valve in the starting arrangement to be provided with one group, they are controlled simultaneously and back down suction valve mechanism on two groups of cylinders of compressor.
Below in conjunction with accompanying drawing to this practical new work further explain.
Description of drawings
Fig. 1 is this practical new embodiment's 1 a schematic representation;
Fig. 2 is this practical new embodiment's 2 a schematic representation.
Embodiment
Shown in Fig. 1; A kind of reciprocal compressor of pressing starting arrangement with band; Include motor 1, interstage cooler 2 and cylinder 3, be respectively arranged with suction valve 4 on the front/ back cavity 31,32 of said every group of cylinder 3, these above-mentioned technical characteristicss also are common in the prior art; So we just have not been described in detail in the present embodiment; In the present embodiment, this compressor also includes band and presses starting arrangement 5, and this band presses starting arrangement 5 to include instrument air valve 51, instrument wind gas holder 52, solenoid valve 53 and back down suction valve mechanism 54; Wherein be provided with on the suction valve 4 on every group of cylinder 3 front/ back cavity 31,32 and back down suction valve mechanism 54, but and suction valve mechanism 54 synchronous working control cylinders, 3 front/back cavities, 31,32 upper inlet valves 4 that back down on cylinder 3 front/ back cavities 31,32 upper inlet valves 4 open or close simultaneously; Adopt such scheme, on the suction valve 4 of each cylinder 3 of reciprocal compressor, all be equipped with and back down suction valve mechanism 54, the power that backs down suction valve mechanism 54 is instrument wind; Backing down the instrument wind of suction valve mechanism 54 is controlled by one or more solenoid valves 53; Compressor backs down 54 work of suction valve mechanism on the suction valve 4 of each cylinder of prestart, suction valve 4 is backed down, thereby the forward and backward cylinder 31,32 of double-acting cylinder is communicated; The pressure of the forward and backward cylinder 31,32 of compressor double-acting cylinder is identical like this; Make the piston force of compressor drop to minimum, starting compressor makes compressor accomplish the zero load basically starting of band pressure then; Be that compressor can be with the pressure starting compressor under the situation of any pressure in the declared working condition scope, very efficient and energy-conservation.
In this practical new embodiment, said band presses the solenoid valve 53 in the starting arrangement 5 to be provided with two groups, and they are independently controlled respectively and back down suction valve mechanism 54 on two groups of cylinders 4 of compressor.Certainly we also can press band the solenoid valve 53 in the starting arrangement 5 be provided with one, back down suction valve mechanism 54 on two groups of cylinders 4 of these solenoid valve 53 controls, and are as shown in Figure 2.
Claims (3)
1. reciprocal compressor of pressing starting arrangement with band; Include motor, interstage cooler and cylinder; Be respectively arranged with suction valve on the front/back cavity of said every group of cylinder; It is characterized in that: also include band and press starting arrangement; This band presses starting arrangement to include instrument air valve, instrument wind gas holder, solenoid valve and back down suction valve mechanism, wherein be provided with on the suction valve on every group of cylinder front/back cavity and back down suction valve mechanism, but and the suction valve mechanism synchronous working control cylinder front/back cavity upper inlet valve that backs down on the cylinder front/back cavity upper inlet valve open or close simultaneously.
