How it works:
The dynamic and rapid motion of the integral parts within a rock drill demands consistent lubrication for seamless performance. Our oil injector is engineered to automate oil delivery, ensuring machine lubrication needs are impeccably met. When operational, the pressure gas enters the inner cavity of the shell (2) via the windward hole (1) of the oil valve, exerting pressure on the oil surface. The oil outlet hole (3) aligns perpendicularly with the pressure gas flow, creating a pressure difference at the outlet (3) under high-speed pressure gas conditions. This ingenuity propels the lubricating oil out through the conveying pipe (4). The oil's small hole (3) then disperses it into the compressed gas pipeline, forming a lubricating mist as it accompanies the compressed gas into the rock drill and gas leg, lubricating every moving component with precision.
Our oil injector is user-friendly, allowing for effortless oil quantity adjustments. Simply manipulate the oil valve handle to control the injection volume. An optimal oil throughput is maintained at 2.5 ~ 3 ml per minute. Visual confirmation is achieved by checking the drilling machine's exhaust for an oil mist, indicating correct lubrication levels.
Caution:
Proper lubrication significantly influences the longevity and sustained performance of the machinery. Avoid grease lubrication to prevent potential blockages within the machine's holes. Obstructed gas flow can lead to poor gas leg lubrication, diminishing machine efficiency and accelerating wear of its parts.

Frequently asked questions
Price advantage
As a unique fusion of industrial prowess and trade expertise, we proudly present unmatched factory-direct pricing!
How long will it take to deliver?
As manufacturers, we promptly initiate production upon order confirmation. For stocked items, anticipate a swift delivery within 15 days. Larger orders may require up to 30 days, ensuring quality is never compromised.
What terms of payment do you accept?
We primarily accept T/T or D/P payment terms. With T/T, a 30% deposit is requisite upfront, while the remaining 70% is settled prior to shipment.
How long are your prices valid?
As a distinguished factory, we maintain stable pricing year-round. Adjustments occur solely under two circumstances: (1) Variations in the U.S. dollar exchange rate; (2) Escalations in labor or raw material expenses necessitating manufacturer price revisions.
What logistics can you use for transportation?
We offer three primary freight transportation methods (1) A robust 80% of shipments traverse the seas to key continents like Africa, South America, and the Middle East. (2) Deliveries to landlocked neighboring nations are facilitated via road or rail.(3) For time-sensitive, lightweight spare parts, we ensure rapid air transport options are available.
