KW Variable Pump Injection Molding Machine
KWV series high efficiency energy saving variable pump injection molding machine is equipped with high efficiency and high response proportional variable pump system. The power output is automatically matched according to the machine action. There's no waste of high pressure throttle and overflow power. It has sensitive dynamic following performance. In comparison with the traditional injection molding machine, energy saving reaches 20-40%. At the same time, it saves water and oil 20-40% that greatly increase profit. This machine applies high performance precise oil filter which keeps the oil pollution grate below NAS8 while in normal continuous working.

According to the national standards of classification and specifications of Bag Filter, the bag filter is divided into five categories. The cleaning method is the main mark of the classification of bag filter.
(1) mechanical vibration class
A cloth bag duster with a mechanical device (including manual, electromagnetic or pneumatic devices) that makes the filter bag vibrate and clear ash, there are two types of cloth bag duster, which are suitable for clearance work and are suitable for continuous working.
(2) split chamber back blowing
It adopts a compartment structure, and uses the valve to switch the air flow by chamber. Under the action of the reverse air flow, the bag filter is forced to shrink or bulge and filter the dust.
(3) back blowing of nozzle
The back blowing air is provided by a high pressure fan or compressor, which is back blowing through the moving nozzle to make the filter bag deformed and jitter and penetrate the filter material.
(4) vibration, reverse blowing and use
Mechanical vibration (including electromagnetic vibration or pneumatic vibration) and back blowing two kinds of dust cleaning methods and bag filter are used.
(5) pulse injection
The compressed air is used as the dust cleaning power, and the compressed air is released in the instant of the pulse injection mechanism to induce several times of the two air high-speed filter bags, so that the filter bag is bulged rapidly, and the cloth bag duster with the impact vibration and the reverse airflow can be cleared.
