Product Details
There are two types of screws. The screw type is mainly used in developed countries, especially in North America, the European Union, Australia and other places. It is widely used by users. The oil flow is smooth, the elevator runs smoothly, and the noise is low. Due to the difficulty of production technology, there are not many domestic manufacturers of screw hydraulic pumps. The screw needs to be produced in a constant temperature workshop (23-24℃) to ensure cutting accuracy.
Valves mainly include: two valves, three valves, and proportional valves. Some villa elevators in East use proportional valves. The advantage is that manual switches are not required during maintenance. Other optional valves include:
Pressure-keeping valve: When the power is suddenly cut off, the elevator can stop nearby without getting stuck;
Explosion-proof valve: To prevent the oil pipe from bursting, EN81 certification is required. The installation location is the connection between the car and the oil pipe;
Loose rope valve: When the elevator is at the base, the wire rope or wire sheet is in a loose state. The loose rope valve can effectively prevent the wire rope from getting stuck elsewhere.
The oil pipe is usually equipped with 2.5 meters.
The leading brand of this accessory abroad is the German brand BLAIN. Our products can effectively replace the products of this factory and ensure that there will be no problems such as intellectual property rights. The price is 5-6 times that of our products.
