Concrete Pump Can Not Contaminate the Environment

<p>(3) Auxiliary motor should be equipped with brakes to prevent kiln&rsquo;s reversal caused by the emphasis of materials and bricklaying when the motor stops. The kiln reversal rate is often close to or above the normal speed, if at that time the auxiliary drive is not torn off and the reducer will become an accelerator, in that case the speed of auxiliary reducer and the motor will be over the nomal speed and reach a million revolutions per minute, so as to cause danger . Therefore, the brake and auxiliary motor must be turned on or power out at the same time. The brake can use the electromagnet type orYWZ-hydraulic push rod brake. Because of the bad bearing lubrication of chocks, wheel and drive part in the low speed, prolonged use of the auxiliary drive is not suitable and generally the continuous operation should not be more than 15 minutes.</p>Henan Daswell Machinery Co., Ltd,is a professional manufacturer and trader specializing in the research, development and production of construction machinery for nearly 30 years.

There are no special requirements on the clutch, the common types are helical gear (Jaw) and the dowel pin type, and overrun the (one-way) clutch can also be used . Overrun clutch can introduces the auxiliary motor torque into the main gear box, and at that time if main motor drives the drive shaft of main gear box by higher speed in the same direction portable water well <a href="http://www.daswell-drill.com/">drilling rig</a>s for sale, the clutch will be in the disengaged position and play the role of separating.</p>
