Product Introduction

PZ-7 type gunite machine is a new and efficient wet sprayed concrete construction equipment. With high efficiency, stable performance, easy operation and maintenance, the job site adaptability and other characteristics. PZ-7 type gunite machine consisted of driven electric motor, reducer, rubber elbow, the rotor body assembly, rubber wheel, seal plate, seat hopper, vibrating hopper, pressed bodies and accelerator conveyor systems, air duct system and electronic control devices and other components.

Scope of application

PZ-7 type gunite machine is widely used in construction machinery, mines, tunnels, culverts, subway, hydropower engineering, underground engineering and high marsh coal mine tunnel shotcrete construction operations: Various types of industrial furnaces, molding spraying refractory lining or repair: a variety of green slope, soil transport and injection.The machine can be used for wave spray can also be used to dry spray and spray job fibers.

Feature

（1）PZ-7-type gunite machine with caster structure, making the move more convenient.

（2）Through rotor chamber no binder , the material smooth, efficient and time-saving;

（3）Four point elastic compensation compression, good sealing effect, little dust next machine,wearing parts with long life ;

（4）Using low pressure high speed vortex air transport, overcome the bonding of material handling, plugging away from the pack and pulse problems, material flow uniform, continuous and stable.

（5）New nozzle, discharge elbow device, to improve spray deposition, less resilient, high quality shotcrete.

（6）Using high-quality wear-resistant lining and high quality rubber sheet, life greatly improved.

usage and operation method

    　　The operator must read the instruction manual and are familiar with the machine structure and operating procedures before induction operation.

  1、 The preparation before starting.A, Inspect the connecting parts are solid, each rotary sliding parts are flexible and reliable. B, observe the cursor, check the gear box oil is sufficient. C, drive motor and power connections, move the motor direction of rotation should be observed turn fonts marked with arrows in the same direction, otherwise the power supply should be synchronized. D, the main gas line, gas line on the next gas, pneumatic vibrator, sprinkler water supply shut-off valve in the closed state, the main gas source tracheal access. Access to water supply pipe, conveying pipe connected to the host. E, adjust the clamping mechanism, manually pre-pressed, and then use a wrench to tighten the bend conveying pipe, open the main gas line shut-off valve on the gas line, observe the pressure gauge at 0.3Mpa around the city, there should be no place rubber flex board gas overflow.

  2、 first open the main gas jet operating road, on the gas line, the next gas valve, open the water supply shut-off valve nozzle, pre-wet rock surface, and then start the motor, turn the vibrator pneumatic valves, mixing materials added to the hopper , began spraying operation. Nozzle operator should work properly adjusted sprinkler water supply, protect the material has a suitable water-cement ratio concrete. Host operating personnel should observe the host side I pores, such as more than material discharged under should be properly reduced the amount of gas supply. Until the machine I No material at the discharge port, the device works so far.

  3、 stop operation shut down before the first stop feeding, with no material ejected at the nozzle, turn off the water supply shut-off valve, while adding a small amount to wet gravel hopper, the hopper and rotor material times the cavity of the residual material washed away, with no material ejected at the nozzle, turn off the motor power and the gas shutoff valve.
