Environmental protection concrete jet is tailored according to tunnel construction requirements, used for dry spraying, tidal spraying concrete equipment, simple and tight structure

It has advanced technology, reasonable structure, stable performance, easy operation and maintenance, long service life and other characteristics, not only

Only suitable for tunnel construction, widely used in mine, culvert, subway, hydropower projects, highway slope protection and other shotcrete construction

Homework.

Dust removal system, almost zero pollution dust emissions, more in line with the social theme of "environmental protection".

The dust removal system adopts the filter drum type dust collector, the dust removal efficiency is up to 99.9%, the resistance is small, the effect is good, the structure is simple, the maintenance is convenient,

Abandon the disadvantages of traditional bag dust collector, efficient and environmental protection.

First, environmental protection grouting machine maintenance

Concrete jet is suitable for the most severe construction conditions, the amount of maintenance is very small, but must pay attention to maintenance

(1) The sealing plate and rotor liner are the key parts of the equipment, and we must pay great attention to their maintenance to ensure that they are working

There is no fault at all times.

(2) Anti-stick chamber and discharge elbow have anti-stick function, generally in the work will not bond. However, after each shift, the rotor and elbow should be opened for inspection and cleaning.

(3) Should often pay attention to the maintenance and maintenance of the reducer:

A. The lubricating oil of the reducer is 50# industrial gear oil (SY1172-77S), or 30# mechanical oil.

b, the temperature rise of the reducer shall not be greater than 400C.

c, after each shift work should be timely clean the reducer surface adhesion mix material and other debris.

d, often observe the oil label, lubricating oil should be filled in time.

e. The lubricating oil should be replaced after 250 hours of accumulated work (about three months).

f, should often check whether the reducer oil leakage phenomenon, timely treatment of leakage.

g, the bearing of the rotor square shaft should be filled with lubricating grease every week. That is, screw off the bolt at the top of the square shaft and fill it with grease.
