Metal Twin-Cylinder Steam Engine Model with Dynamic Balanced Crankshaft RTR

Features:


.K007 is a one-way piston vertical steam engine, equipped with a set of vertical boilers, through the copper conduit to introduce steam into the main engine, steam through the ventilation valve into the cylinder, push the piston to work, piston crankshaft and ventilation valve crankshaft gear linkage, control the intake and exhaust process.
.The engine is equipped with a CNC machined aluminum vertical boiler, featuring a conical combustion chamber for maximum heat absorption and steam generation efficiency. The whole integral CNC molding, the biggest advantage of this design is to reduce the error caused by multi-part assembly, the main body formed at one time is not only extremely solid in structure, but also the accuracy of the whole machine can be controlled to a higher level.
.The K007's innovative design includes a safety valve that automatically releases pressure when it exceeds the set threshold, ensuring safe operation. A water level observation system prevents the boiler from running dry, enhancing the engine's longevity and reliability.
.The brass crankshaft with semi-circular balance design, coupled with precision brass gears with an axial runout of less than 0.005mm, guarantees smooth and efficient power transfer. The large 78mm flywheel shared with the M20 series Stirling engines adds rotational inertia, contributing to the engine's smooth performance.
.Furthermore, the engine boasts stainless steel connecting rods with F684 precision bearings and four F696 high-precision bearings for the gears and crankshaft. These components ensure quiet, stable operation and extend the engine's lifespan.
.Whether you're demonstrating steam power generation with a motor or using it for industrial purposes, the K007 Vertical Piston Steam Engine provides a versatile and reliable solution. Perfect as a standout choice for steam engine enthusiasts and professionals alike.
.Background: .From 1765 to 1790, James Watt made a series of inventions, such as a separate condenser, an insulation layer outside the cylinder, an oil-lubricated piston, planetary gears, a parallel motion linkage mechanism, a centrifugal governor, a throttle valve, a pressure gauge, etc., which increased the efficiency of the steam engine to more than three times that of the original Newcomen machine, and finally invented the industrial steam engine.

If you love your dog…don’t buy this.
Color: Orange
We have a nonaggressive English cocker. She opened the ball every time she played with it. And yes, we are closing it as hard as we can. I do not recommend this toy for any dog! This is a dangerous toy for a dog that is not supervised.

Fun but not for rough play.
Color: Orange
The ball contented our “golden” Jaxson for about 15 minutes. He then thought it was a regular ball and it’s just a little delicate for a big dog. I just wrote it off as a loss. Great idea but should be more durable.
