Embodiment Construction

[0046] Below in conjunction with accompanying drawing and embodiment the present invention is described in further detail:

[0047] Since the existing oil replenishment method can only replenish oil at a certain fixed position in a cycle, the air volume cannot be adjusted, which will cause the problem of insufficient air intake. However, the existing air volume adjustment method has the disadvantages of high cost and high energy consumption.

[0048] see figure 1 , The diaphragm compressor of the present invention is mainly composed of a motor, a base, a crankcase, a crankshaft connecting rod movement mechanism, cylinder parts, oil and gas pipelines, an electric control system and some accessories, which are not specifically limited by the present invention.

[0049]The cylinder part includes a diaphragm 1, a piston 2, a cover plate 5 and a support plate 6. The cover plate 5 with a dome-shaped inner surface and the support plate 6 with a dome-shaped surface are connected to f...

Abstract

The invention discloses a diaphragm compressor and a gas flow adjusting method thereof. After relative positions of an eccentric block and a main shaft are adjusted, the difference of a phase at the beginning of oil replenishment and a phase at the moment when a diaphragm arrivesat a limiting position is accordingly fixed. A compression screw on an expansion sleeve compression component is tightened, so that the relative positions of the eccentric block and the main shaft and the phase difference of oil replenishment are able to be kept fixedthrough an expansion sleeve. A plunger piston is driven to do a reciprocating motion by a bearing matchedthe eccentric block when the main shaft rotates, so that a plunger pump is able to be replenished once with the oil at a certain position after themain shaft rotates by a circle. According to the diaphragm compressor and the gas flow adjusting method, stepless adjustment of gas flow of the diaphragm compressor is achieved by adjusting oil replenishment time of the plunger pump, so that a problem of insufficient gas suction during oil replenishment of an existing diaphragm compressor is able to be solved, and meanwhile, the compressor and the method are more economical, thereby reducing energy consumption.

Description

technical field [0001] The invention belongs to the technical field of diaphragm compressors, and relates to a diaphragm compressor and a gas flow regulating method thereof. Background technique [0002] In the diaphragm compressor, the function of the cylinder is performed by a membrane cavity, the cover plate and the diaphragm with a dome-shaped inner surface form the membrane cavity, and the support plate with a dome-shaped surface is used to limit the lower limit position of the diaphragm. An oil spill valve is arranged on the hydraulic cylinder arranged under the support plate, many oil guide holes are distributed on the support plate, and an intake valve and an exhaust valve are arranged on the cover plate. When the compressor is running, the motor drives the piston in the hydraulic cylinder through the crank linkage mechanism, and the piston pushes the diaphragm to compress the gas through the oil. When the pressure in the diaphragm chamber reaches the exhaust pressur...
