vacuum cleaner constructor's thermal insulation materials need to achieve thermal insulation performance, after thermal insulation (when the ambient temperature is not higher than 25 degrees, the external surface temperature of the thermal insulation structure does not exceed 50 degrees; When the ambient temperature is higher than 25 degrees, the external surface temperature of the insulation structure is 25 degrees higher than the ambient temperature). The insulation structure should be complete within the design service life, and no burning, decay, peeling and other phenomena should occur during use. The thermal insulation structure should have sufficient mechanical strength, which will not be damaged under the action of additional loads such as self-weight, vibration, wind and snow. The thickness of the insulation layer is 100MM, the additional steel is 50MM, the insulation material is selected high temperature glass wool (TYPE1000, δ=50), the thickness direction is divided into two layers, the layer should be staggered, the spacing is not less than one-third of the length or width of the board, the combination should be tight and flat, the outer layer of high temperature glass wool should be laid with galvanized hexagonal barbed wire. Then press down with the self-locking shim. At the lower part of the ash bucket, a steel plate net is laid in the small ash bucket, and then the self-locking gasket is pressed.

vacuum cleaner constructor test operation work items:

First, pay attention to the existence of condensation in the bag room, and the ash removal system is comfortable. To prevent blockage and corrosion, to avoid serious ash accumulation affecting the normal operation of the dust collector equipment.

Second, strictly adjust the cleaning cycle and time. If the cleaning time is too long, the attached dust layer will be cleared off, resulting in leakage and damage to the filter bag.

Third, it is necessary to carefully check the installation of the filter bag, and pay attention to whether the bag is dropped, wear, and loose after use. If so, timely measures should be taken to avoid danger.

4. If the cleaning time is too short, the dust accumulation on the filter bag will increase the resistance value of the dust collector and affect the cleaning effect.

5. Check whether the air volume and the pressure and temperature of each test point are consistent with the design.

6. Always pay attention to the rotation direction, speed, bearing vibration and temperature of the fan.

When determining the performance of the vacuum cleaner constructor, it is necessary to determine the type and scale of the vacuum cleaner constructor structure and dust source facilities. Take measures not to overheat the reinforcement. vacuum cleaner constructor Thermal insulation construction needs to be completed after the dust collector is checked or tested for air tightness. The insulation is used in any weather conditions, so the laying of the shell protection plate is conducive to water drainage. The joints of the inner and outer layers of insulation should be staggered from each other, there can be no holes between the layers and the joints, and the density of insulation should be the density that will not collapse during long-term operation. The distance between the upper and lower angles is about 1000MM, and the distance between the left and right angles is about 500MM. vacuum cleaner constructor after insulation noise should be less than 85 decibels. The expansion joints of each layer of layered insulation should be staggered.
