What is the molding machine used for?

Diaphragm compressor is a reciprocating compressor that relies on the reciprocating motion of the diaphragm in the cylinder to compress and transport gas. The diaphragm is clamped by two limiting plates along its periphery and forms a cylinder. The diaphragm is driven by hydraulic pressure to reciprocate in the cylinder to achieve compression and transportation of gas. Argon membrane compressor has the characteristics of large compression ratio, wide pressure range and good sealing performance. Since its air chamber does not require any lubrication, the purity of the compressed gas is guaranteed. It is especially suitable for the compression, transportation and bottling of flammable, explosive, toxic and harmful, high-purity gases. (? Such as hydrogen, oxygen, acetylene, argon, nitrogen, carbon dioxide, sulfur hexafluoride, etc.). Depending on the exhaust pressure, it is generally made into a single stage or two stages.

The working principle of the argon diaphragm compressor:

The diaphragm compressor is a combination of two systems - the hydraulic oil system and the gas compression system. The metal diaphragm completely separates the two parts

Gas compression system: The gas compression system includes three layers of metal diaphragms and gas inlet and outlet valves.

Hydraulic oil system: The hydraulic oil system includes a crankshaft, piston and connecting rod driven by a motor. The reciprocating motion of the piston generates hydraulic oil pressure and pushes the underlying diaphragm to move to the gas side, thus compressing the gas. Let the gas out. Another component of the hydraulic system is the compensation oil pump, check valve and pressure regulating valve to ensure that the hydraulic oil system is always filled with hydraulic oil during the compression cycle. During the compression process, the check valve isolates the hydraulic oil and the compensation oil pump to prevent the hydraulic oil from flowing back. At the same time, the pressure regulating valve controls the hydraulic oil pressure, thereby forming the pressure of the hydraulic oil system. When the piston is at the bottom, the hydraulic system is compensated by the oil pump. Inject hydraulic oil, the gas enters the membrane chamber through the inlet air inlet valve under the inlet pressure, and the reverse diaphragm is pushed to the bottom of the membrane chamber. The diaphragm cavity is filled with gas. When the crankshaft rotates, the piston moves from the bottom to the top, and the pressure of the hydraulic oil system increases. When the hydraulic oil pressure reaches the compressed gas pressure, the diaphragm moves to the top of the cavity, compressing the gas. When the gas pressure in the membrane chamber reaches the exhaust valve back pressure, the exhaust valve opens, the gas is discharged, the hydraulic system pressure continues to increase, and the diaphragm continues to move to the top to ensure maximum gas displacement and efficiency. When the diaphragm has Completely enters the top of the cavity, and the piston continues to move to the top. At this time, the hydraulic oil pressure control valve is opened through the hydraulic oil pressure, and the hydraulic oil returns to the crankcase. The set pressure of the hydraulic oil regulating valve is higher than the outlet pressure (usually the outlet pressure). 1.2 times the pressure), thus ensuring that the outlet pressure of the gas reaches the design value. At this time, the compression cycle is completed and the piston begins to move toward the bottom. When the piston moves toward the bottom, the clearance gas and the suction gas push the diaphragm group toward the bottom of the cavity, and the entire cycle is completed.
