If you want any details or samples, please speak to us and you will have our quickly reply. Great focus has been paid out on environmental defense and strength saving. we are self-confident to give our consumers versatile and diversified companies. RC collection reverse circulation DTH Hammer is the newest deveXiHu (West EPT) Dis.Hu (West EPT) Dis.ed solution of our business. It is largely utilised for deep exploration drilling and ore grade handle.
It has the pursuing qualities:
one. Primarily based on previous expertise of normal hammers, combined with the functions of recerse circulation hammer, optimized inside construction and perfect power transfer, hence guaranteeing the collection of hammers deilling with quick sleek and steady sampling.
2. The internal construction is extremely easy with elements of high rigidity, as a result guaranteeing EPTT existence and effortless maintenance of the hammer.
3. The EPTion tube adopts an intergrative style and can be changed without having disassembling the hammer. With carburizing therapy, it has good abrasive resistance.
4. Equipped with bits developed with patent. Basically by changing the drill little bit, the same hammer can drill holes of distinct dimensions guaranteeing that the sample is not contaminated.
five. In difficult problem such as free soil, hard rock and a lot of drinking water eXiHu (West EPT) Dis.sts, sampling can be carried out properly.

Operating theory
1. With the piston resting on the percussion bit and the hammer closed up in the drilling position, higher pressure air is directed into the bottom chamber of the Hammer and the piston lifts. This commences the piston cycle.

2. As the piston travels upwards it forms the leading chamber by forming a seal with the inner tube and the ID the piston. Additional movement seals the port that feeds the base chamber and also EPTTltaneously releases the seal on the bottom chamber enabling the air to increase and exhaust down the splines of the percussion little bit. At the very same time the Prime chamber port is opened which feeds the higher pressure air into the earlier shaped best chamber therefore escalating the stress earlier mentioned the piston and forcing it again down.

three.In the course of the down cycle or EPTT stroke the piston reseals the base chamber on the piston bearing bush therefore stopping the exhaust air and creating a chamber of substantial strain air below the piston which forces the piston back up the hammer.

four. EPT the hammer of the base of the hole allows the percussion bit to slide down the EPT sub also enabling the piston to slide down the hammer and relaxation on the piston bearing bush. The piston strike encounter and the strike experience of the percussion little bit can now not come into make contact with hence allowing the cost-free stream of higher force air directly by way of the hammer with no the hammer cycling.
