Introduction

1. Dimension: 1790*720*1270mm, Weight: 455kg.

2. Piston machine, i.e. piston compressor, is widely used in:

Industrial field: Petrochemical, metallurgical industry.
Building and construction field: Pneumatic tools power for air picks, air drills, pneumatic wrenches and other pneumatic tools to provide power, so that these tools can efficiently carry out crushing, drilling, fastening and other operations.
Transportation: Automobile manufacturing, rail transport.

Details

Principle: Air compressor for rock drilling relies on the reciprocating motion of the piston in the cylinder to compress the gas. When the piston moves to the right, the pressure of the left chamber of the piston in the cylinder is lower than the atmospheric pressure, the suction valve opens, and the outside air is sucked into the cylinder; When the piston moves to the left, the pressure inside the cylinder rises, higher than the pressure of the output air pipeline, the exhaust valve opens, and the compressed air is sent to the delivery pipeline.

Motion mechanism

It includes crankshaft, connecting rod, piston, piston rod and so on. It converts the rotary motion of the prime mover into the reciprocating motion of the piston.

Working chamber

Enclosed by cylinder, cylinder head, piston, etc. It is the space for compressed gas.

Valve components

Including suction and discharge valves, which control the inhalation and discharge of gas.

Auxiliary systems

Such as the cooling system is used to take away the heat generated in the compression process, and the lubrication system provides lubrication for the moving parts.

Uses

The working principle of air compressor for rock drilling is that the crankshaft drives the piston to do reciprocating motion, so that the working volume in the cylinder changes periodically, thus realising the inhalation, compression and discharge of air. In rock drilling operation, the compressed air produced by the small piston machine is transported to the rock drill through the pipeline, which provides power for the rock drill piston to do high-frequency reciprocating motion, and continuously impacts the braze tails. It provides a stable power source for the rock drill, so that the rock drill can efficiently drill holes in rock formations for blasting operations, stone quarrying or other stone mining projects, which are widely used in mining, tunnelling, stone quarrying and other fields.

FAQ

Q: How to choose the model with suitable exhaust volume according to the working condition?

A: It needs to be determined according to the actual air consumption, taking into account the number of pneumatic equipments in use at the same time, the frequency of air consumption of the equipments and the amount of air used in a single time, etc. Generally, a margin of 10%-20% should be reserved to cope with the possible peak of air consumption.

Q: What are the requirements for the foundation when installing?

A: The foundation should have enough strength and stability to withstand the weight and vibration of the piston machine during operation, the surface of the foundation should be flat, and the deviation of the level should not be more than 0.5mm/m in general.

Q: How to judge whether the piston machine is running normally?

A: It can be judged by observing whether the pressure and temperature are stable, whether the running sound is normal, whether the vibration is within the permissible range, and the condition of lubricating oil and cooling water.

Q: What are the reasons for the pressure not going up?

A: It may be due to intake valve failure, exhaust valve leakage, piston ring wear, pipeline leakage, etc., which need to be checked and repaired one by one.
