Second, JT (K) YB - * * * J series hydraulic explosion-proof hoist use and product introduction
JT (K) YB - * * * XP series hydraulic explosion-proof hoist and hoist is used to contain the explosive gas such as air mixture of methane and coal dust, used for raising and lowering personnel, material lifting equipment, is the collection machine, electricity, liquid integration of new products.Currently has a monocular and binocular two series, 18 standard specifications of the products, also non-standard specifications can be made according to customer's need.The biggest diameter of 3 meters, the minimum diameter of 1.6 meters.In December 1999, passed by the national mechanical industry bureau and the state coal industry bureau organization expert testimony.And obtained national patent.
Product main drive way the explosion-proof motor directly driving high pressure variable pump, the hydraulic pressure closed loop drive more quantitative and variable hydraulic motor, hydraulic motor through planetary gear reducer drive spindle and drum rotation, under various working conditions to complete the process of ascension.
Third, JT (K) YB - * * * J series hydraulic explosion-proof hoist product technical characteristics:
1, good explosion-proof performance;
2, stable stepless speed regulating performance and low speed performance;
3, the energy conservation effect is obvious:
With hydraulic pressure closed loop drive, under decentralized conditions, remain the state of dynamic braking system, the gravitational potential energy into electricity grid, both to reduce the fever, hydraulic system and save electric energy, energy saving effect is obvious.
Compared with the hydraulic winch hydraulic motor at low speed, high speed hydraulic motor driven hydraulic winch machine high transmission efficiency, energy saving effect is good.
4, technical parameters, reasonable matching, flexible selection leeway big:
Reducer ratio parameters can be reasonably selected according to different load and velocity, hydraulic pump and hydraulic motor parameters to achieve the best match, the variable pump, variable motor speed control method (low speed hydraulic motor is not), which can realize high-speed light load and overload low-speed operation condition, give full play to the equipment capacity.Compared with the hydraulic motor at low speed scheme, under the condition of same power tension or speed can be improved;The maximum tension and maximum speed is the same case, installed power can reduce, can save power.
5, compact structure, small volume, can save cavern construction cost:
By using planetary gear reducer and spindle straight league, high-speed hydraulic motor and connection way of the planetary gear reducer straight league, host short axial dimensions, hydraulic system layout is compact, so the structure is compact, small size, can save cavern construction cost.
6, long service life of equipment, spare parts standard easy to purchase and the price is low, maintenance workload small, integrated operation cost is low.
Compared with low speed hydraulic motor, high speed hydraulic motor is a standard hydraulic components, stable performance, long life, procurement is easy, cheap, reducing the workload of maintenance.Although one-time investment is higher, but the comprehensive operation cost is low.

7, sensitive operation, simple and convenient:
Use only one handle can complete all winch operation process, sensitive, accurate, simple, and reliable operation.
8, slope overloading starting performance stable, safe and reliable.
9, high operation safety and reliability:
Compared with the low speed high torque hydraulic motor transmission scheme, high speed hydraulic motor drive high power hydraulic winch has the very high safety and reliability, "sports car" accident has never seen.
10 and complete safety protection measures, in line with the "coal mine safety regulations" (2001 edition) and coal Ann logo requirements:
Products set up a volume, speed, overload, under voltage, deceleration, brake shoe clearance, zero failure, loose rope chain, depth indicator alarm and overtemperature alarm, liquid level alarm and emergency braking safety protection device.Ann conform to the requirements of the "coal mine safety regulation" and coal logo requirements.
11, has good safety brake performance, brake good reliability:
The pressure valve control hydraulic brake circuit, overloading and devolve on overloading brake deceleration setting function, respectively.Not loose rope lift overloading can be ensured, guaranteeing to devolve overloading to meet the requirements of the safety procedures to reduce speed, and has a good secondary braking performance.
Four, JT (K) YB - * * * J series hydraulic explosion-proof hoist products to adapt to the working conditions and working environment:
Host should be in the ambient temperature of 5 ℃ to 40 ℃ environment, electronic control system should be no more than 1500 meters in elevation (more than 1500 meters can special order), the surrounding air relative humidity is not more than 95% (25 ℃), needed to prevent water and liquids into electrical, no violent vibration, no corrosive gas environment.In addition, still should comply with the instruction manual of the single equipment manufacturer under other conditions.
The ordering information:
1, indicate the hydraulic explosion-proof hoist and hoist model.
2, the biggest increase length, maximum speed, work speed, maximum static tension, static tension, shaft Angle.
3, allow the maximum size of the delegate object and equipment layout requirements.
4, if you have other special needs, can contact the manufacturer.
