Description
Technical field
The utility model belongs to freezer compressor parts, more particularly to a kind of freezer compressor cylinder block.
Background technology
Compressor, it is a kind of driven fluid machinery that low-pressure gas is promoted to gases at high pressure, is the heart of refrigeration system
It is dirty.It is operated after being compressed with piston to it, to row from the refrigerant gas of air intake duct suction low-temp low-pressure by motor
Tracheae discharges the refrigerant gas of HTHP, and power is provided for kind of refrigeration cycle, so as to realize compression → condensation (heat release) → swollen
The kind of refrigeration cycle of swollen → evaporation (heat absorption).In order to ensure the refrigeration of compressor, piston is necessary when being moved back and forth in cylinder holes
There is good air-tightness, therefore, the fit clearance of piston and cylinder holes is unsuitable excessive；Meanwhile during in order to reduce reciprocating motion of the pistons
Frictional force, the generation of the dry friction phenomenon and compressor stuck phenomenon of piston and cylinder holes is avoided, between the cooperation of piston and cylinder holes
Gap is unsuitable too small.At present, the cylinder holes of cylinder block is divided into two kinds of straight cylinder holes and taper cylinder holes, straight cylinder in existing refrigeration compressor
The inner surface in hole is cylinder, and cylinder holes aperture is constant；The inner surface of taper cylinder holes is made up of cylindrical and conical two parts,
Cylindrical cylinder holes part cylinder holes diameter zero draft, aperture are constant；There is certain taper in conical cylinder holes aperture, and pore size is by cone
Degree change.For straight cylinder holes for taper cylinder holes, straight cylinder holes is easy to process.During due to reciprocating motion of the pistons, it is necessary to protect
Demonstrate,prove good air-tightness, the fit clearance of piston and cylinder holes is smaller, and the lubricating oil in the cavity volume of gap is less, then reciprocating motion of the pistons
When gap cavity volume in lubricating oil internal friction it is larger, cause the friction power loss of refrigeration compressor larger, on the other hand due to
Gap cavity volume is small, and during reciprocating motion of the pistons, the supply of lubricating oil may deficiency, it may appear that dry friction phenomenon, easily makes refrigerant compression
The parts wear of machine, more serious meeting cause refrigeration compressor stuck failure occur.
The content of the invention
In order to solve the above problems, the utility model provides a kind of freezer compressor cylinder block, can improve existing cylinder
The deficiency of seat.
Adopted the following technical scheme that for this：A kind of freezer compressor cylinder block, including cylinder body, set in the middle part of the cylinder body
There is crankshaft hole, cylinder body side is provided with cylinder face, and cylinder face center offers cylinder holes, and four installations are additionally provided with cylinder face
Hole, the mounting hole are arranged on four angles in cylinder face；It is characterized in that：A silencing cavity is additionally provided with the cylinder body, it is described
It is circular chamber in silencing cavity, the cylinder face is provided with a bloop, and described bloop one end is located at cylinder face, and passage is another
One end connects circular chamber, and the sound-absorbing material of annular is provided with the chamber；The cylinder face is that the side of crankshaft hole is also opened
Provided with vertical piston hole；The cylinder body lower end is provided with under-chassis, and under-chassis hole, the both sides up and down point in footing hole are provided with under-chassis bottom
Holding pin She You not aided in；Oil leak groove is additionally provided with cylinder body, the oil leak groove is set in a ring centered on crankshaft hole, described
Oil leak bottom land end is provided with outage, and outage is communicated in outside cylinder body.
Further, the crankshaft hole periphery is provided with reinforcement, and the reinforcement is distributed centered on crankshaft hole in X-type.
Further, the attractive material is acoustical cotton.
Further, cut-off block is provided with the outage.
By such scheme, the sound-absorbing material being provided with first in silencing cavity, when can be effectively reduced compressor operating
Noise；Secondly, in the annular oil leak groove of crankshaft hole periphery, lubrication during cylinder inside crankshaft activity can be ensured, while not
During work, machine oil therein can also be collected by dismantling the cut-off block in outage to discharge；Finally set in crankshaft hole periphery
The reinforcement put, the stabilization of crankshaft hole can be reinforced, prevent that bent axle linkage air cylinder seat occurs unexpected at work.
