All

Cause:1. Poor air filter layout: If the air filter cannot filter impurities, the pressure difference between filter inlet and filter outlet will increase, reduce air intake, and cause the compressor to choke and jump.2. The pressure switch or its wiring is not correctly wired: When the pressure switch finds that the pressure in the compressor has reached the set value, it will cut off power to protect the compressor, causing the compressor to jump and shut down.3. The air filter is too small or dirty: If the filter is too small or the filter core is blocked by the filter's too dirty, the pressure inside the compressor will increase and the compressor will jump and shut down.4. Poor heat dissipation: The temperature inside the factory is too high and the heat dissipation of the compressor is poor, resulting in the temperature inside the compressor increasing, and the compressor will jump and shut down.Solution:1. Reasonable layout of air filter: Use pulse filter and air filter combination, and adopt scientific and reasonable air filter layout.2. Correctly wiring the pressure switch: Check and adjust the wiring of the pressure switch to ensure that the pressure switch is operating normally.3. Replace the air filter: Replace the filter with the correct size and replace it regularly, or clean the filter according to the requirements.4. Improve heat dissipation: Install a cooling fan next to the compressor, improve the heat dissipation effect, and equip it with insulation measures.

The cause and solution of the problem of insufficient air volume of the screw air compressorThe cause of insufficient air volume of the screw air compressor is mainly caused by the improper parameter settings of the air compressor or the obstruction in the air path of the air compressor, such as clogging.Solution:1.Check for the clogging of the inlet filter and the exhaust filter, and clean them in time.2.Check the details of the air compressor, such as the air filter, air pipe, safety valve and other connections, whether they are intact and normal.3.Check whether the parameter settings of the air compressor are appropriate and adjust them according to the actual situation.4.Check whether the piston ring, cylinder liner and other parts of the cylinder block of the air compressor work normally.5.Check the working environment of the air compressor and keep the temperature, humidity and other parameters normal.                                                                                                                         ModelPressure(mpa)Displacement(m³/min)Power(kw)Dimension(mm)Weight(kg)Outlet SizeFSS-0.7/7.50.7 1.20 7.5815*700*855450G3/4"FSS-0.8/7.50.8 1.10 FSS-1.0/7.51.0 0.95 FSS-1.3/7.51.3 0.80 FSS-0.7/110.7 1.70 111000*750*1120500G1"FSS-0.8/110.8 1.60 FSS-1.0/111.0 1.40 FSS-1.3/111.3 1.20 FSS-0.7/150.7 2.40 15800*950*1100560G1"FSS-0.8/150.8 2.20 FSS-1.0/151.0 2.00 FSS-1.3/151.3 1.70 FSS-0.7/18.50.7 3.10 18.5900*1150*1260580Rp1-1/4"FSS-0.8/18.50.8 2.90 FSS-1.0/18.51.0 2.70 FSS-1.3/18.51.3 2.20 FSS-0.7/220.7 3.80 221014*800*1200620Rp1 1/4"FSS-0.8/220.8 3.50 FSS-1.0/221.0 3.20 FSS-1.3/221.3 2.90 FSS-0.7/300.7 5.20 30900*1150*1260980Rp1 1/4"FSS-0.8/300.8 5.00 FSS-1.0/301.0 4.30 FSS-1.3/301.3 3.70 FSS-0.7/370.7 6.40 371550*980*13601020Rp1 1/2"FSS-0.8/370.8 6.10 FSS-1.0/371.0 5.70 FSS-1.3/371.3 5.00 FSS-0.7/450.7 8.00 451680*1050*13951085Rp1 1/2"FSS-0.8/450.8 7.70 FSS-1.0/451.0 7.00 FSS-1.3/451.3 5.80 FSS-0.7/550.7 10.50 551800*1250*16002200Rp2"FSS-0.8/550.8 9.80 FSS-1.0/551.0 8.70 FSS-1.3/551.3 7.60 FSS-0.7/750.7 13.60 752020*1250*16502300Rp2"FSS-0.8/750.8 13.30 FSS-1.0/751.0 11.60 FSS-1.3/751.3 9.80 FSS-0.7/900.7 16.30 902020*1250*16502800Rp2"FSS-0.8/900.8 16.00 FSS-1.0/901.0 14.60 FSS-1.3/901.3 12.30 FSS-0.7/1100.7 20.30 1102500*1600*18004000DN65FSS-0.8/1100.8 19.40 FSS-1.0/1101.0 17.30 FSS-1.3/1101.3 14.60 FSS-0.7/1320.7 24.00 1322500*1600*18004500DN65FSS-0.8/1320.8 23.00 FSS-1.0/1321.0 20.00 FSS-1.3/1321.3 18.00 FSS-0.7/1600.7 28.00 1602500*1600*18004800DN65FSS-0.8/1600.8 26.50 FSS-1.0/1601.0 22.50 FSS-1.3/1601.3 20.10 FSS-0.7/1850.7 32.50 1852770*2050*22005200DN65FSS-0.8/1850.8 31.00 FSS-1.0/1851.0 28.00 FSS-1.3/1851.3 25.10 FSS-0.7/2000.7 35.00 2002850*1850*19505800DN80FSS-0.8/2000.8 34.00 FSS-1.0/2001.0 32.00 FSS-1.3/2001.3 26.50 FSS-0.7/2200.7 40.00 2202850*1850*19505900DN80FSS-0.8/2200.8 36.80 FSS-1.0/2201.0 32.20 FSS-1.3/2201.3 28.50 FSS-0.7/2500.7 43.50 2502850*1850*19506600DN100FSS-0.8/2500.8 42.00 FSS-1.0/2501.0 38.10 FSS-1.3/2501.3 34.60 FSS-0.7/3150.7 50.80 3155010*2210*21308000DN125FSS-0.8/3150.8 48.20 FSS-1.0/3151.0 42.60 FSS-1.3/3151.3 39.80 FSS-0.7/3550.7 60.00 3555200*2500*21308500DN125FSS-0.8/3550.8 57.00 FSS-1.0/3551.0 50.00 FSS-1.3/3551.3 45.00

There will always be a certain amount of oil carried over from a compressor. When the compressor it is running hot or is being overworked, oil carryover is made worst. The hot oil fumes then condense in the hose and in the tools. The effect can be reduced by running the compressor as cool as possible, making sure there are no leaks and that the outlet pressure regulator on the compressor is set as low as possible. Ensure there is plenty of ventilation. You can place a cooling fan near the unit in hot weather. A coalescing filter can also be used to reduce oil and condensation.In order to ensure that our screw compressor operates as efficiently as possible, Jinjing has independently developed its own special rotor profile.

There are safety features built into every compressor we sell. These include pressure safety relief valves and thermal cut-outs. Only qualified technicians should be allowed to repair and service your compressor. Common sense prevails, including do not blow compressed air into your face.In order to ensure that our screw compressor operates as efficiently as possible, Jinjing has independently developed its own special rotor profile.

If a compressor is turned on and running at a pressure of 10 bar. Whilst the compressor is being used the pump may not have to be on until the pressure drops to say 8 Bar. Then the compressor pump will turn on and increase the pressure till 10 bar is reached. The time the compressor is on compared to the time the compressor is turned off is the "duty cycle". So if the compressor is on as much as it is off then the duty cycle is 50%. Jinjing compressors are not designed to run higher than a 50% duty cycle. To prevent overheating, a thermal cut-out will turn the compressor off and then turn it back on when the compressor has cooled down enough to run again. In order to ensure that our screw compressor operates as efficiently as possible, Jinjing has independently developed its own special rotor profile.

Obviously, your business does not involve using your compressed air to spray paints, or you would know of problems a little water can cause.  But water’s rap sheet is long and varied and is not limited to crimes against paint jobs.  Water in your compressed air will flush away lubricants in your air tools and air powered machines, increasing wear and causing premature breakdowns.  Also, it can mix with soluble and corrosive solder fluxes in your compressed air piping system and corrode machines and tools downstream.  Water is also corrosive when mixed with compressor oil mist.  Fortunately, water is easy to outsmart.  Appropriately sized refrigerated or desiccant air dryers effectively remove all the moisture from your compressed air.  Add particulate and coalescing filters to remove particulate and oil contamination, and your compressed air will be clean, dry, and ready to effectively perform the work you prescribe for it.  However, as with your compressor, the appropriate size and type of dryer are critical.  You should request that a professional air compressor service company, such as Air Compressor Service, look at your operation and recommend the appropriate equipment.

There are some telltale symptoms of a seriously oversized rotary air compressor:• The compressor is an oily mess,• You have to buy extra oil between services,• You are having problems with your condensate drains,• You are frequently replacing downstream filters, or• You are experiencing corrosion in your compressed air system.If you suspect your rotary air compressor is oversized, ask Air Compressor Service to inspect your compressed air system and determine if changes are indicated.In order to ensure that our screw compressor operates as efficiently as possible, Jinjing has independently developed its own special rotor profile.

The best way to size your air compressor is to measure your actual compressed air use for at least one week of typical operations and allow for reasonable estimates of expected changes.  Air Compressor Service can perform this service for a reasonable cost (free for our existing customers).  Industrial air compressors are too expensive to make a mistake by buying a machine too small for your application, or too big, which is the more common mistake.  One might logically assume that if a 15-hp compressor is good for your application, then a 30-hp would be better, but that is not the case, at least not for rotary machines.  Although a rotary machine (unless it is a variable speed unit) will run at a constant speed even with fluctuating air demand, if the demand is too low for a sufficient time, the machine will shut off.  Then when demand increases it will turn back on.  Frequent on/off cycling causes the machine to “burp” oil each time it shuts down which can cause a variety of problems.

This is an excellent question because the wrong air compressor can cost you big bucks and cause untold headaches.  Each type of compressor (reciprocating, rotary screw, and rotary vane are the primary types) has its own “pros and cons”, but it is not difficult to determine the most appropriate type for your application once you know a little about each one.Reciprocating, or piston, air compressors are the most familiar.  An industrial quality machine will last a long time with routine maintenance.  Reciprocating compressors are also very efficient because they only run when there is a demand for compressed air.  When there is no demand, they turn off, saving wear and tear on the machine and, most importantly, saving on your power bill.  In fact, most of these machines must turn off regularly to cool.  An ideal on/off ratio is 60/40.  Reciprocating air compressors are available in a wide range of sizes from fractional horsepower up to hundreds of horsepower.  A reliable rule of thumb is that each horsepower will produce four cubic feet per minute (4 cfm) of compressed air at 120-150 pounds per square inch (psi) pressure.Rotary screw air compressors run continuously, producing a steady flow of compressed air.  They are suited for applications that require a constant supply of compressed air that would never give a reciprocating machine rest.  However, if the air demand decreases, a rotary screw machine will produce compressed air that is not needed.  This inefficiency will show up in your power bill.  Sometimes a rotary screw machine is used to provide a base amount of compressed air for which there is a constant demand and a reciprocating machine is used to “trim” the system, operating only when demand exceeds the capacity of the rotary screw.  This arrangement can be very efficient.  Also, newer technology variable speed motors can reduce the power consumption of rotary screw machines when air demand diminishes.  Rotary screw compressors are available in the range of five horsepower up.  Each horsepower

All compressor rooms require ventilation. Minimum room ventilation can be calculated from the formula: Qv = 1.06 N/ T for Pack unit Qv= (1.06 + 1.3) / T for Full-Feature unit Qv = required cooling air flow (m³/s) N = shaft input of compressor (kW) T = temperature increase in compressor room (usually 7°C) If the compressor is conducted, the required ventilation is the same as the fan capacity of the compressor. This is mentioned in the instruction manual.In order to ensure that our screw compressor operates as efficiently as possible, Jinjing has independently developed its own special rotor profile.

First, an internal Water Separator Drain (inside of the compressor) is NOT necessary. But it can have some benefits in two cases: 1) Screw without an integrated dryer: Using a water separator drain, we remove some water from the compressed air before it's delivered to the final area of use with less water content. 2) Screw with an integrated dryer: Using it before the dryer, some of the water gets removed before the dryer, this gives the opportunity to choose a smaller-sized air dryer.In order to ensure that our screw compressor operates as efficiently as possible, Jinjing has independently developed its own special rotor profile.

Because an inverter/frequency-driven compressor is not producing more air than needed. A conventional compressor works within a pressure band. When reaching the higher pressure the machine goes into unload mode (the motor is running but no air is produced). When reaching the lower pressure again until it reaches its unload pressure again. An inverter/frequency driven compressor has less unload time and works towards a set pressure value, this makes the inverter compressors in general 30% more energy efficient than a conventional load/unload compressor.In order to ensure that our screw compressor operates as efficiently as possible, Jinjing has independently developed its own special rotor profile.
