 Mine winch
Related introduction
Mine winch The basic requirements of sealing are good sealing performance and long service life, and should strive for compact structure, simple system, convenient manufacturing and maintenance, and low cost. Most of the seals are vulnerable parts, which should ensure interchangeability and realize standardization and serialization.

Types and uses of sealing materials, sealing materials should meet the requirements of sealing function. Due to different sealing media and different working conditions of equipment, different adaptability of sealing materials is required. The requirements for sealing materials are generally as follows: the material has good compactness and is not easy to leak the medium; it has appropriate mechanical strength and hardness; it has good compressibility and resilience, and has small deformation; it does not soften and decompose at high temperature, and does not harden or crack at low temperature.

The performance of mine winch is very good, so it is widely used in the market. Many users will choose the mine winch when purchasing winch, but operate according to the requirements when using, otherwise it is easy to failure. In particular, the winch protection system is easy to have problems, but this problem is generally caused by the brake plate, as long as it is replaced in time, it will be OK.

Mine winch problems, are found in the protection system. For example, if there is a problem with the brake shoe protection, * if the whole circuit is lost, you have to replace the brake pads. The other similar ones are similar to those of the mine winch, but the electrical components and hydraulic station components of the mine winch may make mistakes, but none of them is a big mistake. You have to understand the system before you can repair it. The deceleration point is on the depth indicator. Just change the position of the travel switch of the up and down deceleration points. Place it where you want it to slow down.

Mine winch is now in the market utilization rate is very high, so the winch rope adjustment is now in the market demand is very big. The rope adjustment of mine winch has a good traction effect, which can ensure that there is no accident when the winch is working, and effectively ensure the working efficiency of the winch. The winch can be successfully used by adjusting the rope of the winch.

It is necessary to adopt hydraulic brake and manual brake for mechanical braking in order to avoid the possibility of derailment parking when raising or lowering the mine track. In order to avoid the control of car sliding, DC brake is added to the motor to reduce the motor speed to the brake holding action of hydraulic brake.

Turn the rope adjusting change-over switch to the rope adjusting direction. Operate the relevant solenoid valve action, block the oil inlet of the disc brake of the two rollers, open the oil inlet of the clutch, the clutch will be disengaged under the action of pressure oil, the signal will be announced after the clutch is released, and the relevant solenoid valve will be activated, and the oil inlet of the disc brake of the fixed drum will be opened to make the fixed drum in the state of brake release.

Operate the handle of master controller and service brake to adjust the rope. After the clutch is reset and the reset signal is announced, the winch can recover to normal operation. After adjusting the rope, set the clutch change-over switch to the reset position, and the relevant solenoid valve acts.

The oil inlet of the clutch is blocked, and the oil flows back to the oil tank for pressure relief from another oil return port. The clutch is reset under the action of the reset tension spring. If the gear is not aligned during the reset, the positive and negative inching can be used to improve the machine, so that the gear can be reset to the straight teeth.

In the whole operation process of winch, there are two conditions, the reaction energy is relatively large: one is the regenerative energy reaction when the motor is in the power generation state when the weight is lowered; the other is the regenerative energy reaction when the brake stops. For these two conditions, when selecting the brake unit and brake resistor, we choose the brake unit with larger braking current and the brake resistor with high power and appropriate resistance value.

Mine winch to use DC, AC cut resistance, AC variable frequency resistor, winch hydraulic station voltage regulation is the same. At present, the method of winch pressure regulation basically adopts electro-hydraulic proportional valve. That is, the electric control system sends a control voltage or current to the proportional valve, the control voltage (flow) and the system pressure are basically linear, the greater the voltage (flow), the greater the pressure of the hydraulic station.
