7 Preparation of the product for operation and operation procedure

7.1 Carefully read and follow the instructions in this user manual.

7.2 Carefully open the package, check for completeness, make sure there is no damage.

7.3 Install shock absorbers and wheels on the receiver. Position the compressor so that Free access to the switch and the air supply valve to the consumer. To ensure good ventilation and effective cooling, the belt guards must be at least 1 m from the wall. The floor of the room where the compressor is to be installed must be flat, non-slip, oil-resistant and made of non-combustible, wear-resistant material.

7.4 Check the compliance of the content of the plates on the piston unit, receiver, electric motor with the data of this operation manual.

7.5 Check the oil level on the oil gauge in the crankcase of the piston unit - it should be within the red mark of the sight glass. If necessary, top up the compressor oil recommended in this manual to the medium level. Avoid oil leaks from connections and oil on the external surfaces of the compressor.

7.6 Connecting the compressor to the mainsmust be carried out by specially trained personnel.

With electrical connection, the phase sequence is of particular importance, since this determines the direction of rotation, which must correspond to the arrow on the motor housing and the piston block pulley.

It must be emphasized that even a small amount of reverse rotation time can lead to compressor failure.

7.7 Securely connect the compressor to compressed air consumers using appropriate pneumatic fittings and pipelines.

7.8 When starting for the first time, as well as after a long period of inactivity, it is recommended to put a few drops of compressor oil on the air filter.

7.9 Starting and stopping of the compressor must be carried out only by the switch on the telepressure switch (pressure switch). As the consumer consumes air, the pressure switch of the telepressostat (pressure switch) automatically turns off and on the compressor motor, maintaining the compressed air pressure in the receiver within the specified limits. Pressure control range ?Р=(0.2±0.05) MPa. At the first start-up, as well as at each reconnection, check the correspondence of the direction of rotation indicated on the motor housing and the piston block pulley.

7.10 The telepressure switch (pressure switch) is adjusted by the manufacturer and must not be adjusted by the user.

Setting the pressure of the compressed air at the outlet is carried out by the pressure regulator as follows:

With the valve open, pull up on the pressure regulator knob and turn it clockwise to increase pressure or counterclockwise to decrease pressure;

After checking the set pressure value on the pressure gauge, you should press the handle, thereby fixing the selected value.

The amount of air produced depends on the pressure in the receiver and on its flow rate - if the flow rate is excessive, the pressure gauge shows low values.

7.11 The compressor is equipped with an overload protection device. In the event of a power failure of the electrical network, as well as when working with a duty cycle of more than 60%, automatic operation of the motor protection is possible.

After the engine has cooled down to an acceptable temperature, in compressors SB4/S-50. L B30, SB4/S-100. L B30, SB4/S-100. L В30В the protection device is turned on by turning the switch located on the body of the telepressostat. In compressors SB4/S-50. L V30A, SB4/S-100. L V30A, SB4/S-100. L V30AB - by pressing a button located on the motor unit.

In order to avoid engine failure, intervention in the protection system is unacceptable.

7.12 Upon completion of work, the pressure in the receiver should be reduced to atmospheric.

8 Maintenance

8.1 To ensure the long life and reliable operation of the compressor, perform the following maintenance operations:

After the first 48 hours of operation, check and, if necessary, tighten the cylinder head bolts of the piston block to compensate for thermal shrinkage, tightening torque - 25 Nm;

Daily check the tightness of the air duct connection, clean the compressor from dust and dirt. As a cleaning material, only cotton or linen rags should be used;

Depending on the operating conditions, but at least once a month, clean the suction air filter (filter element). Replace the air filter (filter element) once a year or more often based on the results of an external examination;

After the first 100 hours of operation and every 500 hours thereafter, change the compressor oil. It is not allowed to mix different types of oils. If the color of the oil changes (whitening - the presence of water, darkening - severe overheating), it is recommended to replace it immediately;

Drain the condensate from the receiver daily using the condensate drain cock;

After the first 48 hours of operation and then every 300 hours of operation, it is necessary to check and adjust the tension of the belts and clean them from contamination, since if the tension is insufficient, the belts slip, overheat and reduce the efficiency of the piston unit. When the belts are overtightened, there is an excessive load on the bearings with increased wear, overheating of the electric motor and piston unit. With the correct tension, the deflection of the belt in its middle under the influence of a force of 35-45 N (3.5-4.5 kgf) should be in the range from 5 to 6 mm. Adjust the tension by shifting the electric motor, after releasing the bolts securing it to the platform. The pulley of the electric motor and the pulley of the piston block must be in the same plane;

Monthly check the reliability of the fastening of the piston and engine block to the platform, and the platform to the receiver;

Monthly check the integrity and reliability of fastening of controls, control devices, cables, air ducts;

Clean all exterior surfaces of the piston and motor assembly monthly to improve cooling.

This review will be devoted to the compressor of the Belarusian manufacturer. This is definitely nothing new. The compressor in the compressor equipment market has been known for a long time. SB4/S-100 LB30A is one of the most popular models, both among car services and among private users who have purchased this model for their needs for various work with pneumatic tools. Let's look at the reasons for such popularity.

First of all, when a compressor is selected, they proceed from the goals and objectives for which this unit will be used. Then they look at the main characteristics of the compressor: performance and pressure. And finally, they study the issue of the cost of equipment by selecting best option for your budget. And here the consumer is waiting for big surprises. Russian market literally flooded with a variety of Chinese-made options and offers. Various brands of reciprocating compressors, in pursuit of the buyer's wallet, often offer quite solid performance for moderate money.

Here are just a "big" marketing ploy is that the characteristics are very often "stretched", we are talking primarily about compressor performance, engine power, receiver volume. Therefore, the rule “the miser pays twice” is more relevant here than ever.

But all this does not apply to the Remeza SB4 / S-100 LB30A compressor. Today, this is perhaps one of the few "honest" brands that tries to maintain the quality of its products at the proper level. This applies to both build quality and technical specifications, which really correspond to passport values.

Let's consider this model in more detail. First of all, it should be noted that the compressor is produced in Belarus, at the Remeza CJSC plant (Rogachev) in compliance with all quality standards. Production is certified according to all European standards.

piston block.

The main part of the compressor - a piston block or, more correctly, a cylinder block, is made of cast iron. This allows you to carry high loads during intensive operation. It is worth noting that the piston block that is installed on the SB4 / S-100 LB30A model is of Chinese origin, but with French roots, namely, the piston blocks are produced by the Chinese under license from the French company LACME.

The piston block on the SB4 / S-100 LB30A is a two-cylinder block, which has 2 compression stages. At suction, such a unit gives 420 liters per minute. However, the actual performance, that is, the output performance, will certainly be less. This is due to the peculiarities of the operation of reciprocating compressors in general: the consumption for compression and heating of air, the presence of "dead space" in the cylinders, the process of "throttling". Here are the main reasons that "reduce" the performance of a reciprocating compressor. And SB4/S-100 LB30A is no exception. Because it is a classic belt driven piston compressor.

The engine, which is installed on the SB4 / S-100 LB30A compressor, has a power of 2.2 kW. This is quite enough to disperse such a powerful piston block. The voltage of the compressor is 220V. You can determine this by the name of the compressor itself, the Belarusian manufacturer adds a letter designation - A at the end of the name, which indicates a voltage of 220V. If there is no such letter in the name, then the compressor is definitely at 380.

Previously, the compressors of the Belarusian manufacturer had one big drawback. They were very demanding on the voltage in the Network. This is the Russian reality, when the voltage in the network can drop for one reason or another. This is especially true for operating conditions "in the fields" or a garage, when the quality of the voltage in the network leaves much to be desired. Due to the fact that a sufficiently powerful engine with real characteristics, and not drawn ones, is installed on the compressor, the reduced voltage did not even allow it to “unwind”. Hence the problem stable operation in low voltage networks. However, the Belarusian plant overcame this problem. From October 1, 2015 Remeza plant made changes to the compressor design SB4/S-100.LB30A (as well as SB4/S-50.LB30A, SB4/S-100.LB30AB) by installing a start valve. This design change made it easier to start the compressor when connected to a 220 V power supply network, on which a voltage drop of more than 5% of the nominal voltage occurs when they are turned on. The tests carried out on compressor units equipped with a start valve showed that they confidently start when the mains voltage drops.

The principle of operation of the start valve.

At the initial start-up of the compressor (the pressure in the receiver is equal to zero on the pressure gauge), the start valve is open, the excess pressure in the air line from the pump assembly to the check valve increases more slowly (part of the compressed air is bled through the open start valve), which allows the electric motor to start and gain speed without additional load (similar to idle mode).

After starting the engine, the pressure in the air line increases and when it reaches a value of 1.7-2.2 bar, the start valve closes. When the compressor stops, when the compressor is operating in automatic mode or when the compressor is turned off by a switch on the pressure switch (manostat, pressure switch), air is released from the discharge air line through the exhaust valve located on the pressure switch (manostat, pressure switch), the start valve opens. When the compressor is turned on, the cycle repeats.

Receiver.

Model SB4/S-100.LB30A is equipped with a 100 liter receiver, which is already clear from the designation of the model itself. The receivers are manufactured by Remeza. Steel grade St3ps. The maximum allowable pressure is 11 bar. From the end part of the horizontally located receiver there is a metal tag, on which the main technical parameters are indicated. The production of receivers at the Remeza CJSC plant complies with German quality standards - this is indicated by the Certificate TUVThuringen. It is also necessary to say a few words about the process of painting receivers.

The painting of receivers at the Remeza factory is carried out by powder spraying at high temperatures, this creates another advantage. Powder coated receivers are more resistant to corrosion, scratches and abrasions. Because of this, such a receiver will not rot and will not receive through corrosion. In order to avoid internal corrosion, in the center, on the bottom, a condensate drain valve is installed, which is formed during compressor operation. Therefore, after each work shift, it is necessary to drain the condensate accumulated during the work in the receiver.

Mounted equipment.

Attached equipment SB4 / S-100.LB30A is represented by a pressure switch, pressure reducer and pressure gauge.

High-quality pressure switches are installed on Remeza compressors. This ensures high safety in the operation of the reciprocating compressor. The main task of the pressure switch is to open the electrical circuit that feeds the engine at the moment when the pressure level in the receiver has risen to maximum values. The motor then stops rotating and therefore does not drive the compressor pistons. When the pressure in the receiver drops to a minimum level, the automation restarts the engine and the piston group starts to pump air again.

The pressure switch thus controls the operation of the compressor, automatically protects the piston unit from overheating and ensures its safe operation. Therefore, the more reliable the pressure switch, the better the protection against overheating.

The compressor is also equipped with an overload protection device. In the event of a power failure of the electrical network, as well as when working with a duty cycle of more than 60%, automatic operation of the motor protection is possible.

Two pressure gauges are installed on the SB4/S-100.LB30A compressor. They allow you to monitor the level of pressure. One of them shows the pressure level inside the receiver, the second one shows the pressure level outside.

With the help of a regulator installed on the compressor, it is possible to equalize the required working pressure according to the pressure gauge, depending on the needs of the pneumatic tool or equipment.

At the same time, the protective fence in the form of a mesh protects both the compressor itself from getting various parts into it at the time of operation, and the user himself from accidental injuries when working with the compressor.

In addition, the compressor has large wheels, a rubber shock absorber, and a convenient handle for moving.

Features of operation.

The SB4/S-100.LB30A compressor is a classic piston compressor with a belt drive. It is reliable and easy to operate, so it does not require much attention. Remeza compressors are supplied from the factory already filled with oil - here the “plug and play” principle fully justifies itself. Change the oil after the first 100 hours of operation and every 300 hours thereafter. The manufacturer recommends:

SHELL Corena P100, Mobil Rarus 427;

TNK Kompressor VDL 100;

ESSO Kompressoroel 30 (VCL 100);

TEXACO Compressor Oil EP VD-L 100;

LUKOILCtabio 100;

After the first 8 and 50 hours of operation, the cylinder head bolts of the piston block should be checked and, if necessary, tightened to compensate for thermal shrinkage.

Depending on the operating conditions, but at least after 100 hours of operation or once a month, the air intake filter (filter element) must be checked and, if necessary, cleaned or replaced. Reducing the throughput of the air filter due to its contamination significantly reduces the life of the compressor, increases power consumption, and can lead to failure of the suction, discharge or check valves. The air intake filter (filter element) must therefore be changed every 600 hours of operation.

That's probably all. With proper operation and observance of the rules recommended by the manufacturer, the SB4 / S-100.LB30A compressor will last for many years and will please with its reliable operation.
