Common causes and troubles of vacuum pump

Common causes and troubles of vacuum pump

During operation as well as operation of operators '"Malfunction is unavoidable'" Some basic incidents such as: Do not reach vacuum level, pump overload ... With many years of experience, We have successfully repaired many vacuum pumps. The following are some of the reasons why the vacuum pump failures, and some common vulnerabilities with the hope that the operator can identify and take prevention.

Thermostats for air compressor

Thermostat for air compressor has function of regulating the flow of oil onto the compressor cooler to ensure that the oil temperature and air end are always stable in the allowable temperature.

Kiểm tra xem có bộ phận nối ống nào bị rò rỉ không. Hãy duy trì cách ổn định nhiệt độ bên trong ( dưới 38oC) và nhiệt độ cửa vào khí nén ( dưới 38oC). Đồng thời phải dọn dẹp theo chu kì để bụi, tạp chất không phủ lên tụ điện của bộ làm mát sau và máy sấy khí ( cách khoảng 1-2 tuần)

Compressors equipment repairs

Screw air compressors are in the important position in the industrial process, therefore all aggregates break and troubleshooting affect to industrial process in general and have not expected results. Screw air compressors quality and advantages are undeniable, but every mechanism is run-out eventually, some parts do not operate  stably, some are out of operation. 

compressors equipment repairs

 It is impossible to avoid this situation, but it is possible to decrease expenses for the  screw air compressors repairs. The simplest and the most effective ways is to maintain the compressors equipment in time and not just replace air and oil filters, separator and oil, but make diagnostics of the separate parts addicted to the run-out. Careful compressor equipment revision and diagnostics allow to find small problems and avoid big problems, hence have less expenses and time for the adjustment and repair of the equipment.

The possible variants of the air end break includes:

1. Air end breakage

Air end is the heart of the compressor, it is the most important and most expensive part, therefore it is very important to care about it and avoid replacement of the air end. In case of replacement, the total amount of new air end is about 70% of total price the compressor. But it is the worst variant. Please see chapter “Air end repairs” to know regarding possible variants of block the unit. Unfortunately, if air end is blocked, this problem will not be solved just replacement of the spare parts. It is necessary to make diagnostics, to understand what repairs have to be released.

2.  Drive breakage

In compressor with belt drive, the possible case is belt rupture. The belt is run-out during operation because of abrasion and dust in the air. Usually similar problems are not the case of negative consequences and it is necessary just to replace the belt.
Compressor with gear drive needs more efforts. The most common problem is gear drive block, run-out the gears. These parts and their repairs are quite expensive.
And, at last, compressors with direct drive. The direct drive failure can be connected with flexible coupling break. This coupling is providing connection between drive and air end. In this case the broken part has to be replaced and compressor has to be inspected and checked.

3.Electricalmotor breakage

There are some possible problems: the most expensive is replacing of the electrical motor and more effective is motor winding recovery. However it is possible to avoid the electrical motor break by replacing the motor bearings after vibration appears.

4. Frequency inverter is out of operation

The frequency inverter is designed for the motor speed regulation and offer to decrease power consumption significantly. During the time frequency inverter also can out of the order because of damage the cable, pollution, overheating, or other cases. Almost always they can be repaired, so it is not necessary to replace the whole device.

5. Controller is out of operation:it is necessary make settings of the all compressor parameters, replace all power section elements which are out of order (starters, rely), adjustment one or group of the compressors in adjusted mode.
