Piston Refrigeration Compressors And Accessories

  • Piston Compressor Oil Cooler

    Piston Compressor Oil Cooler

    Ammonia piston refrigeration compressor oil cooler:
    1. Oil coolers are an oil cooling device commonly used in hydraulic and lubrication systems. The device can realize heat exchange between two fluid media with a certain temperature difference, thereby achieving the purpose of reducing oil temperature and ensuring normal operation of the system.
    2. The oil cooler is referred to as oil cooling and is mainly used in piston compressors (ammonia).
    3. Because the model of the piston machine is divided into 100, 125/170.

  • Bearing Shell

    Bearing Shell

    1. The bearing shell is very different from the production year and brand of the piston compressor. It is divided into one hole, two holes and no hole.
    2. The bearing shell is the part of the sliding bearing and the shaft neck contact. The shape is a tile-shaped semi-cylindrical surface. It is very smooth. It is generally made of wear-resistant materials such as bronze and friction reducing alloy. In special cases, wood, engineering plastic or rubber can be used. production. There are two types of bearing shells: integral and split. The integral bearing shell is usually called the bushing. The integral bearing shell has two types of oil grooves and oil grooves. The bearing shell and the shaft neck adopt a clearance fit, and generally do not rotate with the shaft.

  • Valve Flake For Piston Compressor

    Valve Flake For Piston Compressor

    1. Ammonia piston refrigeration compressor suction valve flake and exhaust valve flake are used in a piston refrigeration compressor.
    2. The ammonia piston refrigeration compressor suction valve flake and exhaust valve flake have three types: DN100, DN125 and DN170.
    3. One suction valve flake and one exhaust valve flake are used as a group in the piston refrigeration compressor. The suction valve flake is larger than the exhaust valve flake.
    4. The ammonia piston refrigeration compressor suction valve flake and exhaust valve flake are standard.

  • Valve Group

    Valve Group

    1. The piston refrigeration compressor valve group is also referred to as an exhaust valve group. The piston refrigeration compressor valve group is mainly composed of a valve seat, a valve flake, a spring and a lift limiter.
    2. The piston refrigeration compressor valve group forms a variable working volume with the piston and the gas valve to complete the expansion, suction, compression and exhaust of the refrigerant vapor.
    3. Working principle of piston refrigeration compressor valve group: When the gas valve is working, when the gas pressure under the valve flake is greater than the gas pressure above the valve flake and the self-weight of the spring and the valve flake, the valve flake leaves the valve seat and the valve flake opens. Instead, the valve flake falls and the valve flake closes.

  • Connecting Rod For Refrigeration Compressor Parts

    Connecting Rod For Refrigeration Compressor Parts

    The role of the piston rod:
    1. The piston and the crankshaft are connected, and the force exerted by the piston is transmitted to the crankshaft, and the reciprocating motion of the piston is converted into the rotational motion of the crankshaft.The connecting rod body has three parts, the part connected with the piston pin is called the connecting rod small head; the part connected with the crankshaft is called the big connecting rod, and the connecting part of the big head and the small head is called the connecting rod shaft.
    2. The connecting rod is divided into high pressure and low pressure, the high voltage of the bipolar piston machine and the low pressure of the low level piston machine.

  • Cylinder Liner For Piston Compressor

    Cylinder Liner For Piston Compressor

    The main functions of the cylinder liner in the piston refrigeration compressor:
    1. Forming a variable working volume with the piston and the gas valve to complete expansion, suction, compression, and exhaust of the refrigerant vapor;
    2. Guide the reciprocating motion of the piston.
    3. The cylinder liner is embedded in the cylinder barrel and forms a combustion chamber together with the piston and the cylinder head.
    4. Cylinder liners are divided into low pressure and high pressure.

  • Shaft Seal For Piston Compressor

    Shaft Seal For Piston Compressor

    1. The screw refrigeration compressor shaft seals usually include movable ring, retaining ring and O-ring.
    2. The shaft seal for refrigeration compressor has two models, Model 1 and Model 2.
    3. In the refrigeration compressor, the refrigerant is prevented from infiltrating into the system to the outside or the air, and a shaft seal must be provided between the extended end of the crankshaft and the body. Friction ring type shaft seals are widely used in open compressor series. The structure comprises a spring, a spring seat, a sealing ring, a fixing ring and a movable ring.

    Piston For Piston Compressor Parts

    Piston For Piston Compressor Parts

    Pistons are versatile, regardless of the machine manufacturer.
    1. Piston Set: The piston set is a general term for pistons, piston pins and piston rings. The piston group is driven by the connecting rod to make a reciprocating linear motion in the cylinder, thereby forming a variable working volume together with the cylinder to realize the processes of suction, compression and exhaust.
    2. Model: 100, 125, 170.
    3. Used medium: Ammonia.
    4. Use range: Piston compressor unit.

  • Asbestos gasket

    Asbestos gasket

    1. The complete asbestos pad of the refrigeration compressor is made of high quality asbestos board and is durable.
    2. The complete asbestos pad of the refrigeration compressor can be edited according to the customer's requirements if it has special size requirements. It is also convenient for customers to adjust the size when needed.
    3. The complete asbestos pad of the refrigeration compressor is not easy to get wet, and the volume is small, which does not take up space. Therefore, it is very convenient to store.
